    OPINION
    AND
    ORDER OF THE
    BOARD
    (by R.C.
    Flemal)’:
    SUMMARY
    OF TODAY’S ACTION
    Pursuant to Section 17.5 of the Environmental Protection Act
    (Act), the Board today updates the Illinois regulations that are
    identical in substance to U.S. Environmental Protection Agency
    (U.S.
    EPA) regulations implementing the Safe Drinking Water Act
    (SDWA).
    The Board rules are contained in 35 Ill.
    Adni.
    Code 611.
    The text of the adopted amendments appears in the order segment
    of this document, following the discussions.
    The Board’s responsibility in this matter arises from the
    Environmental Protection Act
    (Act)
    (415 ILCS
    5
    (1992)).
    The
    Board is charged therein to “determine, define and implement the
    environmental control standards applicable in the State of
    Illinois”
    (415 ILCS 5/5(b)).
    More generally,
    the Board’s
    rulemaking charge is based on the system of checks and balances
    integral to Illinois environmental governance:
    the Board bears
    responsibility for the rulemaking and principal adjudicatory
    functions,
    whereas the Illinois Environmental Protection Agency
    (Agency)
    is responsible for carrying out the principal
    administrative duties.
    The latter’s duties include administering
    the regulations that are today adopted.
    Section 17.5 of the Act provides for quick adoption of
    regulations that are “identical in substance” to federal
    The Board wishes to acknowledge the efforts of staff
    attorney Michael J. NcCambridge as principal drafter of its
    opinions and orders in this matter,
    under the direction of
    Senior
    Attorney Kathleen N.
    Crowley.

    regulations.
    Section 17.5 provides that Title VII of the Act and
    Section
    5 of the Illinois Administrative Procedure Act
    (APA)
    shall not apply.
    Because this rulemaking is not subject to
    Section
    5 of the APA
    (5 ILCS 100/5-3 5 and 5-45),
    it is not
    subject to First Notice requirements or Second Notice review by
    the Joint Committee on Administrative Rules
    (JCAR).
    As discussed more fully below,
    this rulemaking involves
    revisions of the Illinois public water supply regulations.
    It
    includes the federal amendments to the SDWA regulations that
    occurred from January
    1 through December 31,
    1994.
    During this
    time, U.S. EPA issued corrections to the lead and copper rules on
    June 30,
    1994, corrections to the monitoring requirements for
    unregulated contaminants on July
    1,
    1994,
    and consolidated
    monitoring regulations on December 5,
    1994.
    The Board also uses
    this opportunity to note a recent judicial decision that affects
    the implementation of certain aspects of the lead and copper
    rules.
    PUBLIC COMMENTS
    In its March 16,
    1994 proposed opinion and order, the Board
    requested public comments on the proposal.
    Notices of Proposed
    Amendments appeared in the Illinois Register on March 31,
    1995,
    at 19
    Ill. Reg.
    4785.
    The Board accepted comments for 45 days
    after the Notices appeared, until May 15,
    1995.
    The Board has
    now acted promptly to adopt amendments based on the federal
    amendments involved in this docket.
    The Board received three comments on the proposed
    amendments:
    PC
    1 Secretary of State
    (April 17,
    1995, by Connie Bradway,
    Index Department, Administrative Code Division)
    PC
    2 Agency
    (May 17,
    1995,
    by Connie
    L.
    Tonsor, Assistant
    Counsel, Division of Legal Counsel)
    PC
    3 Agency
    (June
    5,
    1995,
    by Connie L.
    Tonsor, Assistant
    Counsel, Division of Legal Counsel)
    Pc 1 suggests corrections to the Code format of segments of the
    text of the amendments.
    PC
    2 comments generally on the rules and
    offers several suggestions for correction and clarification of
    the amendments.
    PC
    3
    is
    a supplement to PC
    2 in which the Agency
    notes conversations it has had with U.S. EPA relating to
    discrepancies in the analytical methods amendments.
    In addition,
    the Board received a document entitled “Identical First Notice
    Line Numbered Version” on March
    28,
    1995 from JCAR,
    which also
    suggests corrections to the text.
    All revisions made in response
    to the comments are summarized below on page 25, under the
    heading “Public Comment—Based Revisions”.
    Substantive comments
    3
    are addressed in the course of the topical discussions below,
    where appropriate.
    ROUTINE DISCUSSIONS
    At the end of the opinion segment of this document are two
    routine discussions generally made a part of identical—in—
    substance opinions.
    The first is a summary of the history of the
    Illinois SDWA identical-in-substance proceedings.
    The second is
    a summary of some of the conventions the Board uses in deriving
    identical—in—substance rules.
    We present those discussions for
    general informational purposes.
    FEDERAL ACTIONS COVERED BY THIS RULEMAKING
    AND GENERAL DISCUSSION OF THE PRESENT ISSUES
    The SDWA program was drawn from 40 CFR 141
    (national primary
    drinking water regulations or NPDWRs),
    40 CFR 142
    (NPDWR5
    implementation), and 40 CFR 143
    (national secondary drinking
    water regulations or NSDWR5).
    The nominal update period of the
    R94-23 docket is from January
    1,
    1994 through June 30,
    1994.
    The
    nominal update period of the R95-3 docket is from July
    1,
    1994
    through December
    31,
    1994.
    U.S. EPA amended its SDWA regulations
    three times during the two update periods.
    The federal actions
    during the time-frame of this docket were as follows:
    59
    Fed.
    Reg. 33860
    (June 30,
    1994)
    (Lead and Copper
    corrections)
    59
    Fed. Reg.
    34320
    (July
    1,
    1994)
    (Monitoring for
    Unregulated Contaminants)
    59
    Fed. Reg.
    62470
    (Dec.
    5,
    1994)
    (Analytical Methods)
    The amendments to the lead and copper rules, adopted by U.S.
    EPA on June 30,
    1994, corrected typographical errors, clarified
    language, and restored special primacy provisions inadvertently
    omitted by U.S. EPA in earlier rulemaking.
    U.S. EPA stated that
    it intended to clarify the regulations in order to simplify
    implementation.
    The amendments of July
    1,
    1994 similarly
    corrected typographical errors, clarified language, and corrected
    errors in regulatory text from U.S. EPA’S stated intent in the
    Phase
    I, Phase II, and Phase V rules.
    The amendments of December
    5,
    1994 approved new and updated existing analytical methods.
    Essentially, these
    last updates are intended to eliminate
    multiple uses of procedures, which have resulted in the use of
    multiple versions of methods for different purposes.
    Another related aspect of this update concerns a judicial
    challenge to the federal lead and copper regulations.
    In
    4
    American Water Works Association v.
    EPA,
    40 F.3d 1266
    (D.C.
    Cir.
    1994), the federal appellate court vacated an aspect of a
    definition instrumental to implementation of certain of the lead
    and copper regulations.
    Although the Board did not base
    substantive amendments on the federal judicial decision, we added
    a Board Note to the affected segment of the rules to indicate the
    action and state its probable impact on the enforceability of the
    affected rule.
    CONSOLIDATION OF DOCKETS
    Although the Board generally deals with each update batch
    separately, we deal with them together in this instance because
    it is expeditious for the Board and it will avoid misleading the
    public.
    The present SDWA amendments of December 5,
    1994 affect
    some of the same provisions as the amendments of June 30,
    1994.
    Generally, where such an overlap of substance occurs, the
    Board is inclined to pull the later amendments forward and deal
    with them in the earlier docket.
    This avoids duplication of
    effort and confusion in the regulated community.
    This often
    allows dismissal of the later docket.
    The Board is dealing with
    the later amendments together with the earlier amendments and did
    not delay
    in this instance for the following reasons:
    1)
    The July 1 and December 5,
    1994 amendments were directly
    affected by the June 30,
    1994 amendments; and
    2)
    Prompt action on the July
    1 and December
    5,
    1994 amendments
    will facilitate implementation of the regulations.
    Although we are dealing with all amendments together, the Board
    does not believe that outright dismissal of the later R95-3
    docket is appropriate; the amendments are major in importance.
    For these reasons, the Board has consolidated the two
    proceedings,
    in order to avoid any possible confusion and to
    particularly draw the attention of the interested public to both
    sets of amendments.
    The Board also notes that the December 5,
    1994 amendments
    are the earliest amendments involved in this consolidated
    rulemaking.
    They occurred within six months of the June 30,
    1994
    amendments, the latest amendments included.
    DETAILED SECTION-BY-SECTION-ANALYSIS
    The Board amends the Illinois drinking water regulations in
    response to these federal actions.
    The following detailed
    section—by—section discussion focuses on the details of the
    actions taken.
    5
    Routine, General Amendments——All Sections
    The Board has performed a number of standard revisions to
    the text of the federal rules.
    The rationale behind many of
    these is discussed in the August
    9,
    1990 opinion and order
    in
    docket R88—26
    (Phase
    I rules), and we will not repeat those
    discussions here.
    Others are so minor as to warrant no
    explanation.
    The standard changes are as follows:
    1.
    Where the federal rules require an action “by” a certain
    date, the Board renders that as “on or before” that date.
    2.
    We have changed various subsections to the active voice,
    rather than following the federal use of the passive voice.
    3.
    We have updated all Board Notes to reflect the 1993 version
    of the Code of Federal Regulations and to reference the June
    30,
    1994 Federal Register action, where appropriate.
    4.
    We have made a number of changes based on the unique
    attributes of the Illinois regulatory scheme and on certain
    stylistic preferences,
    as described in the Addendum re
    Standardized Modifications of Federal Text at the end of
    this opinion.
    General Housekeeping Amendments
    Completing a practice begun
    in an earlier update docket, the
    Board changes all remaining references to the United States
    Environmental Protection Agency to “U.S.
    EPA” throughout the text
    of the regulations.
    This includes the redesignation of
    “Inorganic Methods” as “U.S. EPA Inorganic Methods”.
    This
    occurred in Sections 611.100,
    611.102,
    611.110,
    611.111, 611.112,
    611.113,
    611.130,
    611.201,
    611.212,
    611.300, 611.301, 611.310,
    611.311,
    611.351,
    611.359,
    611.480,
    611.490, 611.500, 611.510,
    611.522,
    611.523,
    611.560, 611.600,
    611.601,
    611.605, 611.611,
    611.612,
    611.630,
    611.646,
    611.647,
    611.648, 611.860, 611.Table
    E, and 611.Table Z.
    In many of these provisions, this is the
    only amendment.
    While the Board has traditionally waited until
    Sections open for other amendments to make stylistic revisions
    and minor corrections, we will make these changes now in order to
    complete the change and make the regulations internally
    consistent.
    Further,
    since the volume of substantive amendments
    is light in this update,
    it is convenient to make these changes
    now.
    A similar set of amendments relates to correction of
    citations to the Illinois Compiled Statutes and the format of
    those citations.
    These corrections occurred at Sections 611.100,
    611.101,
    611.125,
    and 611.220.
    All citations to the older
    Illinois Revised Statutes have been deleted where they appeared.
    6
    The statutory titles have been corrected at Sections 611.100,
    611.125, and 611.220.
    Other general amendments were ancillary to the substantive
    amendments in this docket.
    The following discussions
    specifically highlight these amendments.
    Definitions——Section 611.101
    U.S. EPA corrected 40 CFR 141.2 at 59 Fed.
    Reg. 34322
    (July
    1,
    1994)
    by amending one definition and adding another.
    The
    amendments to the definition of “initial compliance period”
    related to citation format and correction of a cross—reference to
    the list of inorganic chemical contaminants
    (IOC5)
    for which the
    initial compliance period did not begin on January
    1,
    1993.
    The
    added definition was of “transient non-community water system”,
    which U.S. EPA abbreviated as “TWS” and the Board abbreviated as
    “transient non—CWS”.
    Section 611.101 corresponds with 40 CFR 141.2.
    There was no
    amendment necessary to the definition of “initial compliance
    period” in the Illinois regulations.
    The citation format and
    citation corrections are meaningless because the Board inserted
    the IOC names in place of the cross-references when initially
    adopting the definition.
    The Board foresaw the need and added the definition of
    “transient non—community water system” when initially adopting
    the regulations,
    so the addition of the definition was
    unnecessary.
    However,
    U.S. EPA defined the term directly, and
    the Board’s former definition appeared in terms of what a
    transient non—CWS was not.
    (It was not a community water system
    and not a non—transient non—CWS.)
    The definition is now amended
    to use U.S. EPA’s language.
    We note, however, that we retained
    our abbreviation for the term,
    “transient non—CWS”, rather than
    use the federal “TWS”, because throughout the course of these
    SDWA updates, one consistent informal complaint expressed to
    Board staff has related to the confusing over-use of
    abbreviations.
    For this same reason, we have deleted the former
    abbreviation “TNCWS”, which appeared nowhere in the text of the
    regulations but in this definition.
    The Board invited comment on our definitions of “initial
    compliance period” and “transient non—community water system”.
    The Agency commented by PC
    2 that the Illinois definition of
    “transient non—community water system” accurately reflects the
    language of the Act and is consistent with the federal
    definition.
    The Agency did, however, suggest that the Board
    correct the word “water” in the parenthetical in the above
    paragraph of the opinion, which the Board has done.
    As to the
    definition of “initial compliance period”, the Agency commented
    that it strongly agreed with the original substitution of
    7
    contaminant names for cross—references because it makes the
    regulations “more meaningful and useful to the regulated
    community”.
    The Agency further commented that it verified the
    accuracy of the Board’s listing of contaminants.
    Effective Dates——Section 611.120
    U.S. EPA amended 40 CFR 141.6(a) at 59
    Fed. Reg.
    34322
    (July
    1,
    1994)
    to correct the reference to the exceptions from the
    general effective date and to correct a reference in one of the
    exceptions.
    It amended 40 CFR 141.60(a) (3)
    at 59 Fed. Reg.
    34324
    (July
    1,
    1994) to change the effective date for the MCL for
    endrin from January 17,
    1994 to August 17,
    1992.
    The Board has
    an effective date reference at Section 611.120 that is
    fundamentally different from the federal provision.
    Without
    regard to when the federal regulations become effective, the
    Illinois regulations are effective at a later date:
    when they
    are filed with the Secretary of State.
    That is the general rule
    on effective dates recited in Section 611.120.
    Therefore,
    amendments based on the federal corrections are unnecessary.
    Special Primacy Requirements-—Section 611. 130
    U.S. EPA added 40 CFR 142.16(d) at 59 Fed. Reg. 33864
    (June
    30,
    1994).
    This sets forth the special primacy requirements for
    state lead and copper programs.
    U.S. EPA explained that the
    Phase II amendments of July 30,
    1992 at 56 Fed. Reg. 3526
    (Jan.
    30,
    1991)
    erroneously deleted these provisions.
    The recent
    amendment restored them.
    The Illinois regulations do not include a counterpart to 40
    CFR 142.16 because such
    a provision is unnecessary.
    This rule
    applies only to the state,
    and not to the regulated community.
    Therefore,
    no amendment is necessary based on this federal
    action.
    The Agency agreed in PC
    2 that the lead and copper
    special primacy requirements apply to the state and that no
    amendment of the regulations is necessary on this basis.
    U.S.
    EPA corrected a reference to another agency’s
    regulations
    in 40 CFR 142.62(g) (2), at 59 Fed. Reg. 33864
    (June
    30,
    1994).
    The reference was to Food and Drug Administration
    rules relating to the quality of bottled water.
    The Board corrected the federal error
    in the original
    adoption of corresponding Section 611.130(e)(4)(C).
    Therefore,
    the only amendment we make at this time is to update the citation
    in the Board Note at the end of subsection
    (e) to include the
    Federal Register citation to the federal amendments to 40 CFR
    142.62(g).
    The Agency agreed in PC 2 that the prior amendments
    to Section 611.130(e)
    dealt with this federal amendment.
    8
    Finally, U.S. EPA corrected the listings of BAT in 40 CFR
    142.62(a)
    at 59 Fed. Reg. 34325
    (July
    1,
    1994).
    40 CFR 142.62(a)
    lists BAT for all contaminants for use in obtaining relief from
    an MCL.
    In the amendments, U.S. EPA corrected the headings for
    “PTA” and “GAC”, removed PTA as BAT for alachlor, corrected the
    spelling of dalapon,
    and changed BAT for hexachlorobenzene from
    OX to GAC.
    These corrections prompted no substantive amendments
    to the Illinois regulations,
    since the Board never adopted the
    table.
    Rather,
    as is explained in the Board Note to Section
    611.130(c),
    we relied on the listings of BAT at Sections 611.301
    and 611.311 for the sake of consistency.
    The only amendment
    prompted by these corrections
    is the deletion of the discussion
    in the Board Note of the probable U.S. EPA error,
    since U.S. EPA
    has now corrected that error.
    The Agency commented in PC 2 that
    the federal grant of primacy approval on June 27,
    1994 to the
    Illinois Phase II, Phase IIB, Phase V, and lead and copper rules
    indicates federal approval of the inclusion of BAT in Section
    611.130(c).
    Water Supply Operator Certification--Section 611.220
    The Board initially opened Section 611.220 only for routine
    amendments.
    However,
    in PC
    2, the Agency recommended that the
    Board amend subsection
    (c), which requires certification of SWS
    and mixed—system operators under the Water Supply Operator
    Certification Act (415 ILCS 45
    (1994)).
    The Agency pointed out
    that that statute applies only to community water systems;
    it
    does not apply to non-CWSs.
    The Department of Public Health
    regulates non-CWS5.
    40 CFR 141.70(c) requires plant operation by
    “qualified personnel who meet the requirements specified by the
    State”.
    The Agency noted that non-CWS5 do not need a certified
    operator,
    but only one who receives annual training.
    The Agency
    did not state exactly how it wished the Board to amend this
    provision.
    In response, the Board notes that 35 Ill. Adm. Code 611
    applies only to CWS5,
    and not non-CWSs.
    In adapting the federal
    regulations, however, we have retained all references to non—
    transient, non-CWS5 and transient non-CWS5 wherever the federal
    regulations provided for them.
    It has been our understanding
    through the Agency that Public Health intended to incorporate the
    Part 611 rules for application to non-CWSs by reference.
    Therefore, while it may seem superfluous to add language that
    applies in an area outside the scope of the Board’s and Agency’s
    statutory authority,
    there is some appeal in amending this
    requirement to expedite its application to non-CWS5 if Public
    Health chooses to do so.
    The problem is that the Board is not
    fully informed on either Public Health’s authority and
    requirements for approval of operators or on its position on the
    Board tailoring that authority and requirements into our
    regulations.
    9
    The Board agrees that since we have thus far accommodated
    Public Health incorporation of our rules, we will add language
    that makes it clear that requirements other than the Water Supply
    Operator Certification Act apply to non-CWS5 through Public
    Health.
    We have cited 77
    Ill.
    Adin. Code 900.40(e), which is the
    only requirement of which we are presently aware.
    The Board made
    this addition to a Board Note,
    rather than directly to the
    regulatory requirements, because we are unsure of Public Health’s
    position on our effort to aid its SDWA implementation and
    enforcement efforts.
    Inorganic MCLs and BAT-—Sections 611.300
    & 611.301
    U.S. EPA corrected the spelling of “ultraviolet” irradiation
    best available treatment technologies
    (BAT)
    in the key to the BAT
    codes in 40 CFR 141.62(c)
    at 59 Fed. Reg.
    34325
    (July 1,
    1994).
    Since the Board corrected this misspelling in the original
    adoption in R93-1, no change was necessary based on this federal
    action.
    By PC 2, the Agency stated that it concurs in the prior
    correction of the federal error in Section 611.301.
    PC 2 expressed the Agency’s confusion as to the proposed
    amendment to Section 611.300(a),
    since the Board failed to
    discuss that amendment in the proposed opinion.
    The Agency
    stated that the amendment appeared correct, but it could not
    understand the purpose for the amendment.
    When U.S.
    EPA
    consolidated the ICC analytical methods on December 5,
    1994
    (59
    Fed. Reg.
    62467),
    it added methods for analyzing arsenic, even
    though there is, as yet, no federal MCL for this contaminant.
    The Board used this opportunity to rely on the more updated
    federally-derived methods,
    in Section 611.611, and delete the
    older methods in Section 611.612.
    The added statement at Section
    611.300(a)
    asserts that the supplier is to rely on the methods of
    Section 611.611, rather than the methods of Section 611.612,
    which apply to the other state-only MCL5.
    The Agency commented
    in PC 2 that the rules should state that analyses for arsenic are
    made by the methods of Section 611.611, but compliance must be
    calculated under Section 611.612.
    Since this is correct, the
    proposed amendment to Section 611.300(a) was revised to reference
    Section 611.611 for analytical methods.
    A similar reference was
    added to Section 611.612(f), which sets forth the analytical
    procedures for the state—only old MCLs.
    Other amendments not discussed in the proposed opinion
    relate to a shift to reliance on the federal cyanide MCL in
    Section 611.301.
    The federal MCL became effective, and the state
    MCL in Section 611.300(b)
    expired,
    on January 17,
    1994.
    This
    meant deletion of the identical state-only MCL in Section
    611.300(b).
    It also meant deletion of the Board Note discussion
    of the expiration of the state-only MCL upon the effective date
    of the federally-derived MCL.
    10
    Organic MCL5 and BAT--Section 611.311
    U.S. EPA corrected 40 CFR 141.61 at 59
    Fed.
    Reg. 34324—25
    (July
    1,
    1994).
    Subsection
    (b)
    lists all the BAT for each
    contaminant.
    U.S. EPA corrected the heading to the table by
    removing “synthetic” because the table sets forth BAT for the
    VOCS as well.
    U.S. EPA further corrected the table by
    integrating the amendments of
    57 Fed. Reg.
    31846
    (July 17,
    1992)
    into the pre—existing text.
    The format of those amendments had
    the effect of replacing the prior table,
    rather than adding to
    it.
    Finally, U.S. EPA corrected the MCL for aldicarb in
    subsection
    (c)
    from 0.003 mg/i to 0.002 mg/i.
    The only amendment necessary for the Board was the
    correction of the aldicarb NCL at Section 611.311(c).
    We
    properly integrated the table when making the R93-1 amendments,
    and we never included a heading for the table, so those
    amendments were not necessary.
    We note, however, that U.S.
    EPA
    indicated GAC as BAT for toxaphene.
    Therefore, we remove the
    Board Note at the end of subsection
    (b) that discussed that based
    on the preamble discussion of the rule,
    U.S. EPA apparently
    intended GAC as BAT but used PTA in the text of the rule.
    Since
    U.S. EPA has now indicated its intent by removing PTA as BAT for
    this contaminant, that discussion is no longer necessary.
    PC 2
    indicated that the Agency verified the aldicarb sulfone MCL
    listing, and it agrees with the deletion of the Board Note.
    Ap~licabi1ityof Corrosion Control—-Section 611.351
    U.S. EPA amended 40 CFR 141.81(c) at 59 Fed. Reg.
    33862
    (June
    30,
    1994)
    by adding a sentence at the end of the
    subsection.
    This statement clarifies that a small—sized or
    medium—sized system supplier must implement corrosion control
    treatment when it exceeds the lead or copper action level, even
    if the supplier is deemed to have optimized corrosion control.
    U.S. EPA stated at 59 Fed.
    Reg. 33861 that some persons were
    confused by federal
    language in the second sentence of that
    provision
    (i.e., whether “any such water system” excluded the
    small—sized or medium—sized system supplier).
    The added sentence
    makes it clear that this was not U.S. EPA’S
    intent.
    35 Ill. Adm. Code 611.351(c)
    derives from 40 CFR 141.81(c).
    In originally codifying subsection
    (C),
    the Board divided
    it into
    several subsections.
    We further revised the language where it
    was patently unclear.
    As a consequence, we do not see that
    subsection
    (c) (2)
    is subject to the interpretation that U.S. EPA
    now deems wrong.
    Nevertheless,
    the Board has added subsection
    (C)
    (4) to embody the added federal clarifying language.
    We note
    that we have deviated from the federal language slightly,
    in that
    we have continued our use of “supplier”
    in place of the federal
    “system”.
    PC 2 indicated that the Agency continues to support
    the Board’s substitution of “supplier” for “system”
    in Section
    11
    611.351(c)
    and throughout the regulations.
    It also stated the
    Agency’s opinion that the added sentence will serve to add
    clarity to the rules.
    Lead Service Line Replacement—-Section 611.354
    U.S. EPA did not amend 40 CFR 141.84 in the present update
    periods.
    Rather, this provision was the subject of litigation in
    federal court that resulted in a decision during the time—frame.
    The court in American Water Works Association v.
    EPA,
    40 F.3d
    1266
    (D.C.
    Cir.
    1994),
    vacated U.S. EPA’s definition of “control”
    over a lead service connection to the extent it would require the
    supplier to exert “control” over
    a privately—owned service
    connection.
    Under this decision, U.S. EPA cannot require a
    supplier to replace a lead service line if it lies on private
    property.
    This is different from U.S. EPA’s approach under 40
    CFR 141.84(d),
    which requires replacement ofa
    lead service line
    up to the building inlet unless
    it can demonstrate that it does
    not control the line,
    and 141.84(e), which presumes supplier
    control over the service line in the absence of certain proofs by
    the supplier to the contrary.
    In past actions
    (e.g.,
    the federal stay of the aldicarb
    MCL5), the Board has indicated actions that render federal
    requirements less than fully enforceable.
    Our statutory mandate,
    under Section 17.5 of the Act, does not allow the Board to base
    regulatory amendments on judicial or administrative decisions.
    Rather, the Board explains the fault at the federal level and
    states our intent that no one interpret the Illinois regulation
    more stringently than the corresponding federal regulation.
    In
    the present instance, the Board followed this practice by stating
    in the Board Note at Section 611.354(e) (2) (B)
    that the Illinois
    definition of “control” over a service line should give the state
    regulations the same effect as the federal definition gives the
    U.S. EPA regulations.
    The Agency responded to our request for
    comments by stating that the Board Note clarifies the Board’s
    intent for the regulated community and that it anticipates that
    U.S. EPA will move to amend 40 CFR 141.84(d) and
    (e).
    Water Quality Parameters--Section 611.357
    U.S. EPA amended 40 CFR 141.87 at 59 Fed. Reg.
    33862
    (June
    30,
    1994)
    by revising the introductory text.
    U.S. EPA explained
    that as originally drafted, the possible interpretation was that
    only large system suppliers that exceed the lead or copper action
    level would need to sample for water quality parameters.
    To
    clarify that this was not its intent, U.S. EPA added a comma
    after “all large systems” in the opening language.
    As for Section 611.357, the Board clarified the
    corresponding Illinois regulation in its original adoption.
    In
    this instance, the Board added the comma for the sake of clarity,
    12
    so no substantive amendment is necessary.
    Therefore,
    the only
    amendment is updating the end Board Note to include the Federal
    Register citation to the federal amendment.
    In response to our
    solicitation for comment,
    in PC
    2 the Agency stated that it
    agrees with the original clarifying correction previously made by
    the Board.
    Reporting Requirements--Section 611.360
    U.S. EPA clarified 40 CFR 141.90(g) to expressly allow
    10
    days for reporting data on additional monitoring.
    U.S. EPA
    stated that it originally expressly stated the 10-day limit with
    regard to reporting other monitoring data elsewhere in this
    section, and that the lack of a 10-day limit for additional
    monitoring was potentially confusing.
    The Board amended Section 611.360(g)
    to reflect the federal
    10-day limit.
    The only amendment that deviates from the federal
    amendments is the addition of the word “of” at the beginning of
    this subsection to correspond with its appearance in the federal
    base text.
    PC 2 indicated that the Agency continues in its
    agreement with the prior correction made by the Board.
    Updated Analytical Methods and Corrected Inorganic and
    Microbiological Monitoring Requirements——Sections 611.102,
    611.359,
    611.526,
    611.531,
    611.560,
    611.611
    & 611.612
    U.S.
    EPA amended the chart and introductory text of 40 CFR
    141.89(a)
    at 59 Fed.
    Reg.
    33862
    (June 30,
    1994).
    The amendments
    were intended to correct typographical errors in the methods for
    orthophosphate.
    U.S. EPA also used the opportunity to revise the
    methods references to the latest versions of its own methods
    manuals,
    Standard Methods,
    and ASTM references.
    Finally, U.S.
    EPA sought to clarify the practical quantitation levels
    (PQLs)
    for lead and copper in 40 CFR 141.89 (a) (1)
    (ii).
    This also
    consolidated and changed the language describing reporting lead
    and copper levels in that paragraph.
    The Board amended the appropriate incorporations by
    references in Section 611.102 and the methods listed in Section
    611.359 to correspond with the federal amendments.
    This required
    the addition and deletion of methods incorporated in Section
    611.102,
    and revisions to the stated availability of some
    documents.
    As is explained more fully below, U.S. EPA
    consolidated the analytical methods for the lead and copper
    program into the inorganic methods in 40 CFR 141.23(k),
    at 59
    Fed. Reg.
    62466 and 62470
    (Dec.
    5,
    1994).
    The Board followed the
    federal lead and consolidated the methods in corresponding
    Section 611.611(a).
    This leaves a cross—reference at Section
    611.359(a)
    to Section 611.611(a)
    for the methods.
    13
    As to the changes to define PQLs and reporting lead and
    copper levels, the Board has effected the federal amendments with
    minor deviation.
    We overlooked the effect of the December 5,
    1994 amendments when we assembled the proposal for public comment
    by misreading them as replacing all of Section 611.359(a).
    Now
    realizing this error, we incorporated the June 30,
    1994
    amendments into subsection
    (a).
    The Board added the PQL
    definitions as parenthetical language in subsections
    (a) (1) (B) (i)
    and
    (a) (1) (B) (ii) to make these both a single sentence that fits
    more neatly into the broader structure of subsection
    (a) (1) (B).
    We also added the PQL5 as parenthetical language in subsection
    (a) (3)
    and added the words “lead and copper” for the sake of
    clarity at that subsection.
    Since the Board previously added a
    definition of PQL to Section 611.350(b)
    based on the Federal
    Register preamble discussion of this concept, we revised the
    Board Note reference to cite the regulatory amendment as the
    source of this definition.
    The Board invited comment on the amendments to Section
    611.359.
    The Agency had several comments relating to the
    analytical methods.
    It stated that it agrees with the insertion
    of a cross—reference
    in Section 611.359 for the lead and copper
    methods.
    U.S. EPA amended 40 CFR 141.21(f) at 59 Fed. Reg. 62466
    (Dec.
    5,
    1994).
    This provision sets forth the microbiological
    analytical procedures for coliforni bacteria.
    The amendments
    updated the existing methods, each of which is referenced in the
    new 18th edition of Standard Methods, including the colilert
    test,
    formerly available from Environetics,
    Inc.
    U.S. EPA also
    approved a new test for the simultaneous detection of total
    coliforms and E.
    Coli,
    the “Colisure Test”, available from
    Millipore Corp.
    U.S. EPA amended 141.74(a)
    at 59 Fed. Reg. 62470
    (Dec.
    5,
    1994), which sets forth the analytical and monitoring
    requirements for demonstrating compliance with the filtration and
    disinfection requirements.
    U.S. EPA updated the methods to the
    18th edition of Standard Methods for total coliforms, fecal
    coliforms, heterotrophic bacteria,
    free chlorine, total chlorine,
    chlorine dioxide, and ozone,
    including the addition of 4500—Cl
    E,
    for total chlorine.
    A method from “Methods for the Determination
    of Inorganic Substances in Environmental Samples”
    (abbreviated in
    the rules as “U.S.
    EPA Environmental Inorganics Methods”)
    and one
    from Great Lakes Instruments,
    Inc.
    (GLI) were approved for
    turbidity measurement.
    Section 611.526 of the Illinois regulations derives from 40
    CFR 141.21(f),
    and Section 611.531 derives from 40 CFR 141.74(a).
    The Board followed the federal microbiological, turbidity, and
    residual disinfectant methods amendments in Sections 611.526 and
    611.531.
    We added the appropriate methods referenced by U.S. EPA
    14
    to the incorporations by reference in Section 611.102.
    For this
    reason, we added definitions in Section 611.102(a)
    for “Colisure
    Test” and “ONGP-MtJG test”
    (by amending the former definition of
    “14740-MUG test”).
    In subsection
    (b), the Board has added the
    appropriate methods, but we have also deleted the following,
    having not found their surviving use elsewhere in the
    regulations:
    Standard Methods
    (14th ed.):
    Method 214A; Standard
    Methods
    (16th ed.):
    Methods 212,
    214A, 408C through 408F, 410 B
    and C,
    907A,
    908 through 908E,
    and 909 through 909B; Standard
    Methods
    (17th ed.):
    2320,
    2510,
    2550,
    and 4500—03;
    “Microbiological Methods for Monitoring the Environment, Water
    and Wastes”, and the reference to Environetics,
    Inc. for the
    colilert test.
    The Board invited comment on our update to the analytical
    methods of Sections 611.526 and 611.531.
    The Agency commented in
    PC 2 on both Sections.
    In PC
    2, the Agency stated that it
    verified the desirability of the methods deletions with U.S.
    EPA.
    U.S. EPA Region V agreed that deletion is appropriate.
    As to
    Section 611.526, the Board has made one correction to spelling
    and repunctuated three subsections in response to the Agency’s
    comments.
    As to Section 611.531, the Agency noted that the Board
    had inadvertently omitted methods for heterotrophic bacteria and
    turbidity that appeared in the table in 40 CFR 141.74(a) (1) and
    for total chlorine by amperometric titration that appeared in the
    table in 141.74(a)(2).
    We have corrected those errors by
    restoring the omitted methods, reorganizing the appearance of the
    information in subsections
    (a) (2) and
    (b) (2) to more closely
    parallel the federal table, and by appropriately renumbering all
    subsections.
    The Agency commented further in PC 3 on discrepancies in the
    text of the 40 CFR 141.21(f) (3) and 141.74 (a) (1)
    amendments
    (corresponding, respectively, with 35 Ill. Adm. Code
    611.526(c)and 611.531(a)).
    The first discrepancy relates to the
    inclusion of footnote 4
    in the table
    in section 141.21(f) (3)
    for
    both total coliform fermentation technique and the presence—
    absence coliform test.
    U.S. EPA stated to the Agency that this
    was appropriate.
    The second discrepancy is that U.S. EPA
    included the Colisure Test and presence-absence coliform test in
    section 141.21(f) (3) but not in section l41.74(a)(1).
    U.S. EPA
    responded that this was deliberate because the surface water
    treatment rule (section 141.74) requires quantification of total
    coliforms, whereas the total coliform rule (section 141.21)
    requires testing only for the presence or absence of coliform
    bacteria.
    U.S. EPA further informed the Agency that the Colisure
    Test was approved for testing treated water only, not for testing
    raw water.
    Thus, U.S. EPA also deliberately included Standard
    Methods Method 9221 A and B in section 141.21 but 9221 A, B and C
    in section 141.74 because quantification of coliforms is not
    necessary under the total coliform rule.
    The Agency requested
    15
    that the Board include a Board Note to help avoid confusion,
    which we have done at Sections 611.526(c)
    and 611.531(a) (2) (A).
    The Agency stated in PC
    3 that U.S. EPA indicated its intent
    to alter footnotes
    1 to the tables at
    40 CFR 141.21(f)(3) and
    141.74 (a) (1) to encourage but not require keeping samples below
    5°C during transit.
    U.S. EPA will also revise footnote 2 to
    section 141.21(f) (3)
    and footnote
    3 to section 141.74(a) (1)
    to
    indicate that both false positive and false negative results must
    be below 10 percent when performing the total coliform
    fermentation technique using lactose broth.
    The Board takes note
    of these assertions, but will wait until U.S. EPA takes action
    before amending the corresponding Illinois rules.
    Finally, the Agency suggested,
    in its marked-up copy of the
    proposed amendments attached to PC 2, that the Board add the
    method number to the reference to the Standard Methods recipe for
    nutrient agar.
    U.S. EPA gave just the Standard Methods pages
    reference.
    In response to the Agency’s comment, the Board has
    added a reference to Method 9221 B at Section 611.526(f)(2).
    As already mentioned, the amendments at 59 Fed. Reg.
    62466
    (Dec.
    5,
    1994)
    consolidated the inorganic chemical contaminant,
    lead and copper, and sodium analytical methods into 40 CFR
    141.23(k) (1),
    in a single table.
    U.S. EPA simultaneously amended
    40 CFR 141.41(d)
    (special monitoring for sodium) and 141.89(a) to
    replace the methods formerly listed at those locations with
    cross—references to the table of methods.
    Many of the methods
    appear as updated versions of the same methods, with updates
    references, and some are approvals of newer methods.
    U.S. EPA amended 40 CFR 141.23 at 59 Fed. Reg. 34323
    (July
    1,
    1994)
    to make corrections to the text.
    One correction was the
    consolidation of the two listings of inorganic methods,
    in former
    paragraphs
    (k) (1)
    and
    (k) (4), into a single table by the deletion
    of former paragraph
    (k) (1) and the renumbering of former
    paragraph
    (k) (4) to paragraph
    (k) (1).
    The corrections to
    paragraphs
    (a) (1) and
    (a) (2)
    replaced references to “the
    compliance period beginning January
    1,
    1993” to “the initial
    compliance period”.
    The corrections to paragraphs
    (a) (5),
    (f) (1), and
    (i) (2)
    added antimony,
    beryllium,
    cyanide,
    nickel,
    and thallium to the list of inorganic contaminants for which a
    supplier must monitor.
    The corrections to the table of methods
    at paragraph
    (a) (4) (i)
    corrected the listings for the atomic
    absorption platform furnace method and removed a redundant
    footnote to the concentration method for Method 200.7A because
    the concentration method was already a part of the method.
    At
    paragraph
    (c) (1), U.S. EPA corrected “once every three years” to
    “during each compliance period”.
    Finally,
    at a handful of
    locations, paragraphs
    (c) (5) (iii)
    ,
    (i) (1),
    (i) (2)
    ,
    (k) (1), and
    (q) (3), U.S. EPA corrected grammar and spelling errors.
    16
    The Board made the federal corrections to 40 CFR 141.23
    in
    the corresponding provisions where necessary.
    Since the Board
    made some of the corrections in the original adoption of the
    regulations, those corrections are unnecessary now.
    We amended
    the table of detection limits in Section 611.600(d)
    to delete the
    concentration method of 200.7A; all others of the corrections to
    the table were made in initial adoption.
    The Board followed the
    federal corrections and substituted “during each compliance
    period” for “every three years” at Section 611.603 (a) (1).
    We
    corrected Section 611.606(a)
    to add antimony, beryllium,
    cyanide,
    nickel, and thallium.
    Although not prompted directly by a
    parallel federal amendment,
    the Board added these five
    contaminants to the listing in Section 611.603(g).
    We also
    changed “and”
    to “or” at Section 611.609(a)
    and
    (b), having
    already made the other corrections to these provisions.
    The
    extensive renumbering of Section 611.611 was unnecessary, partly
    because the initial deviation in structure from 40 CFR 141.23(k),
    and partly because the amendments of December 5,
    1994 further
    caused renumbering by deletion of provisions.
    The Agency
    commented in PC 2 that it generally agrees with the corrections
    proposed.
    The Board amended Sections 611.359(a),
    611.611(a),
    and
    611.630(d)
    to correspond with the federal amendments.
    Where the
    use of an updated reference or method supplants the use of
    earlier editions, the Board made the appropriate additions and
    deletions at Section 611.102.
    In the course of making these
    amendments, we relied on federal amendments to the methods for
    the secondary MCLs at 40 CFR 143.4(b), at 59 Fed. Reg. 62470
    (Dec.
    5,
    1994),
    to update the analytical methods for the state-
    only MCLs for iron, manganese,
    and zinc at Section 611.612(f).
    Again, we then deleted the references in Section 611.102 to the
    older methods.
    The Board invited comment on our approach to the inorganic
    analytical methods of Sections 611.611 and 611.612 and the
    incorporations by reference in Section 611.102.
    The Agency
    commented by PC
    2 that the Board should reorganize the appearance
    of U.S. EPA documents incorporated by reference in Section
    611.102 to ease locating them without regard to their source
    (U.S. EPA EMSL,
    NTIS,
    etc.).
    The Agency further noted omissions
    in our listing of inorganic analytical methods in Section
    611.611(a).
    The Agency in PC 3 requested correction of the
    format of certain Standard Methods methods titles in Section
    611.510(b)(12).
    Finally, the Agency prompted Board discussion,
    above,
    of amendments to Section 611.300(a)
    omitted from the
    proposed opinion.
    Those amendments also involved changes in
    Sections 611.611 and 611.612.
    In adopting the amendments to the Section 611.102
    incorporations by reference,
    the Board has endeavored to
    implement the Agency’s suggestion one step further:
    we
    17
    centralized the listing of all references in subsection
    (a) and
    cross—referenced the availability of each.
    Thus,
    Section
    611.102(a)
    is now a combined listing of abbreviations and a
    short—name listing of references.
    It includes the short name for
    each federal or non—federal document incorporated by reference as
    used in the text of the rules and the definition of each
    abbreviation used.
    This subsection
    (a)
    listing refers the reader
    to the source of each document,
    as set forth
    in subsection
    (b),
    and the listings of documents by source
    in subsection
    (b) now
    cite the short name for each document.
    In addition to the
    changes directly prompted by the Agency’s comment, the Board
    further reviewed each appearance of references throughout the
    text of the regulations and in subsections
    (a) and
    (b) and
    attempted to conform the respective usages for each reference.
    Although these changes are more extensive in some regards than
    those requested by the Agency, the Board believes that these
    changes will aid in locating documents incorporated by reference.
    However,
    to the extent the Agency may have suggested a
    fully—integrated listing of all federal incorporations by
    reference, the Board has declined to do that in this docket.
    Section 611.102
    is already a very large and tedious provision.
    Originally it was organized by document source, with the aid of a
    list of defined abbreviations.
    Section 611.102 is now a list of
    defined short names for references that includes an indication of
    source, with a complete listing of the incorporations under each
    source.
    If the present “half—way” organization of the
    incorporations is inadequate to address the Agency’s concerns
    over ease of use, the Board might further amend this provision in
    the future.
    One possible alternative might be a listing of
    complete references alphabetically arranged by short name.
    In light of the Agency’s comments, the Board rechecked all
    the inorganic analytical methods in Section 611.611(a)
    against
    the federal amendments of December
    5,
    1994.
    This did reveal a
    small number of omissions that we have now corrected in adopting
    the amendments.
    Thus, the Standard Methods method for ICP
    arsenic
    is now Method 3120 and that for ion chromatography
    nitrate
    is Method 4110, and the ASTM method for nitrate by
    automated cadmium reduction is Method D3867-90 A.
    The Board
    further changed the format and content of several methods titles
    in response to this re—examination prompted by the Agency.
    Rather than use the former or U.S. EPA methods designations, the
    Board opted in favor of the format and exact titles given by the
    sources themselves.
    Thus,
    for analyses for ionic species, we
    added the Standard Methods charge designations for 4500-CN,
    4500—F,
    4500—N03, and 4500-N02 we further retained our way of
    setting forth methods subdesignations by a space,
    rather than by
    a dash like U.S. EPA
    (e.g., Standard Methods Method 4500-Si F or
    ASTM D3559-90 D).
    Other changes include standardization of the
    references to “Inductively—coupled plasma—mass spectrometry”
    18
    (lower case “mass”), “Standard Methods,
    18th ed.”,
    “Atomic
    absorption”
    (spelling of “absorption”),
    “ASTM Method”
    (addition
    of “Method”),
    and “Waters Test Method B-lOll”
    (addition of
    “Waters
    Test
    Method”).
    The
    Board
    has
    at
    least
    temporarily
    employed
    a
    version
    of
    the
    names
    for
    inorganic
    analytical
    method
    types,
    e.g.,
    “ion
    chromatography”,
    “inductively—coupled plasma—mass spectrometry”,
    “atomic absorption, platform furnace technique”,
    etc.,
    that is
    based on our prior names, modified slightly by some of the
    corresponding federal names.
    Alternatives suggested by the
    Agency’s marked—up copy attached to PC
    2 are to revise the names
    to more closely parallel the original source name for the method
    or to change them to the federal name for the method.
    We did not
    modify the names in response to the comment at this time, but may
    revisit this matter in the future.
    The Agency suggested a number of other changes.
    First,
    the
    Agency requested a cross—reference at Section 611.611(a)
    to
    Section 611.480, which authorizes the approval of alternative
    analytical methods.
    We included language to this effect in
    subsection
    (a) and in Section 611.645, which sets forth the
    organics methods.
    The Board further corrected this subsection by
    adding the words “or directly without digestion” in response to
    PC 2.
    We also added “Manual”
    and method subdesignation “C” at
    subsection
    (a) (8) (A),
    (a) (8) (B), and
    (a) (8) (C)
    in response to the
    Agency’s comments.
    Others of the Agency’s recommendations
    highlighted errors in the methods that the Board’s review
    disclosed,
    as discussed above.
    These and other of the changes
    are indicated in the table under “Public Comment—Based Revisions”
    below on page 25.
    Finally,
    as discussed above, beginning on page nine,
    the
    Board proposed amendments to Sections 611.300 and 611.301
    relating to the January
    17,
    1994 expiration of the old MCL for
    cyanide when the federal MCL for cyanide became effective.
    That
    discussion relates how we revised those proposed amendments in
    adopting them.
    The revisions also involved adding language at
    611.612(f) directing attention to Section 611.611(a)
    for the
    methods for analyzing arsenic.
    U.S. EPA amended the special monitoring provision of Section
    141.40 at 59 Fed. Reg. 62469
    (Dec.
    5,
    1994).
    The only
    unregulated inorganic contaminant is sulfate.
    U.S. EPA used a
    cross reference to the methods for secondary contaminants at 40
    CFR 143.4(b), as amended at 59
    Fed. Reg.
    62471,
    for the methods
    for sulfate.
    The methods used were from the reference called
    “U.S.
    EPA Environmental Inorganic Methods” by the Board,
    from
    ASTM,
    and from Standard Methods
    (18th ed.).
    The Board codified
    these at Section 611.510(b) (12).
    19
    The Board invited comment on our codification of the methods
    for the inorganic unregulated contaminant at Section 611.510.
    The Agency commented in PC
    3, which has prompted revisions.
    The
    Agency noted that U.S. EPA is inconsistent in its use of the
    ionic charge in methods designations in 40 CFR 143.4.
    The Board
    borrowed the sulfate methods from those federal secondary MCL
    provisions.2
    As discussed above,
    the Board reviewed the naming
    format for all the methods, and this resulted in a number of
    changes in Section 611.510.
    Another correction,
    prompted by a
    marked—up copy of the Board’s proposed amendments attached to PC
    2,
    is the changing U.S. EPA Organic Methods method 507 to method
    508 for propachlor in subsection
    (b) (11).
    Finally, the Board review of the proposed amendments, made
    in the course of following up on the various comments, revealed
    an additional omission from the text.
    U.S.
    EPA amended 40 CFR
    141.22(a) at 59 Fed.
    Reg.
    62466
    (Dec.
    5,
    1994).
    The amendment
    replaced the methods previously listed for turbidity measurement
    with a cross—reference to the updated consolidated methods at 40
    CFR 141.74(a) (1).
    The Board neglected to include this amendment
    in the proposed text.
    We now correct that oversight and amend
    Section 611.560(a) (2)
    to reference Section 611.531(a)
    for
    turbidity measurement methods.
    Undated Analytical Methods and Corrected Organic Monitoring
    Requirements——Sections 611.641,
    611.642. 611.645.
    611.646,
    611.648
    & 611.685
    U.S.
    EPA corrected 40 CFR 141.24 at 59 Fed. Reg.
    34323
    (July
    1,
    1994)
    and updated the analytical methods at 59 Fed. Reg. 62468
    (Dec.
    5,
    1994).
    The corrections included the removal and
    reservation of subsections
    (a) through
    (e), which pertained to
    monitoring for the old MCL for endrin, which U.S. EPA removed in
    the Phase V rules when it promulgated
    a new MCL for that
    contaminant.
    Thus,
    since the Phase V regulations became
    effective,
    40 CFR 141.24(a) through
    (e) were without substantive
    effect.
    However,
    in updating the bC,
    SOC, and TTHM analytical
    methods, at 59 Fed. Reg.
    62468
    (Dec.
    5,
    1994), discussed below,
    U.S. EPA codified the updated methods as subsection
    (e).
    Section 611.641 formerly corresponded with 40 CFR 141.24(a)
    through
    (d), and Section 611.642 corresponded with subsection
    (e).
    Rather than repeal these two Sections, the Board has
    consolidated former Section 611.642 into Section 611.641 as
    subsection
    (d).
    We revised the Board Notes to Section 611.641 to
    2
    Since most of the federal secondary MCL provisions are not
    mandatory for state programs, the Board has never adopted them.
    The exception, which U.S. EPA does require as an element of a state
    program,
    is the secondary MCL for fluoride at Section 611.858.
    20
    indicate the broader former source of derivation of this
    provision and to relate that this Section now applies only to
    state-only MCL5
    (for aldrin, DDT, dieldrin, heptachlor,
    heptachlor epoxide,
    2,4-D,
    and TTHM).
    The Board has retained
    these provisions,
    rather than repeal them, because they provide
    for monitoring and analyses for these state-only MCLs.
    Until
    some interested person should justify the repeal of the state—
    only MCLs in the context of a general rulemaking under Section
    27
    of the Act, we believe that we must retain these Section 611.641
    requirements.3
    The Board invited comment on our retention of and
    amendments to Section 611.641 and received none.
    At 59 Fed.
    Reg.
    34323
    (July
    1,
    1994),
    U.S. EPA amended 40
    CFR 141.24(f) (4),
    (f) (7),
    (f) (10),
    (f) (14),
    (f) (16),
    (h) (4) (i)
    (h) (10),
    and
    (h) (12) to correct the text.
    There is no need to
    make corresponding amendments to the Illinois regulations for a
    variety of reasons.
    The correction to paragraph
    (f) (4) was
    limited to correcting a cross—reference citation format; the
    Board originally substituted the language in Section 611.646(d).
    The corrections to paragraphs
    (f) (7)
    and
    (f) (10) were corrections
    to references to “non—transient,
    non-community water systems”,
    which the Board originally referred to properly as “NTNCWSs”
    in
    Section 611.646(g).
    Paragraphs
    (f)(14) and
    (h)(10) pertain to
    composite sampling, for which there are no corresponding Illinois
    provisions.
    The correction to paragraph
    (f) (16) was limited to
    an incorporation by reference, which the Board properly codified
    at Section 611.102; further,
    as discussed below,
    U.S. EPA
    subsequently removed and reserved paragraph
    (f) (16).
    The
    correction to paragraph
    (h) (4) (i)
    changed “the compliance period
    starting January
    1,
    1993” to “the initial compliance period”, the
    wording used initially by the Board in initially adopting
    corresponding Section 611.648(d).
    The correction to paragraph
    (h) (12) related to consolidation of endrin into this provision.
    As is discussed below,
    the December
    5,
    1994 amendments removed
    this paragraph.
    Parallel corrections to 40 CFR 141.24(f) (14) and 141.28
    pertained to laboratory certification.
    40 CFR 141.24(f) (14)
    provision corresponds with Section 611.646(t).
    U.S. EPA
    substituted “certified laboratory” for “approved laboratory”.
    Examination of the Illinois text revealed that not only was a
    parallel amendment necessary to subsection
    (t), but also to
    subsections
    (q),
    (q)(1), and
    (q)(2).
    40 CFR 141.28 corresponds
    with Section 611.490 of the Illinois regulations.
    Since the
    Board already used “certified laboratory” in both the Section
    ~
    Alternatively, proof that these provisions render the
    Illinois drinking water program less stringent than or inconsistent
    with the federal requirements would justify their removal using
    identical—in—substance procedures.
    21
    heading and text of that provision, no amendment was necessary.
    The Agency commented that it concurred with these corrections to
    Sections 611.646 and 611.648.
    At 59 Fed.
    Reg.
    34323, U.S. EPA removed and reserved 40 CFR
    141.24(g), which pertained to monitoring for the Phase I VOC5.
    As previously observed by the Board in docket R93-1, the
    expansion of federal subsection
    (h) rendered subsection
    (g)
    without substantive effect.
    The Board has repealed corresponding
    Section 611.647 as a result.
    The Agency commented in PC 2 that
    it agreed with the repeal of Section 611.647.
    At 59 Fed. Reg. 62468-69
    (Dec.
    5,
    1994), U.S.
    EPA updated
    and consolidated nearly all the organic chemical
    (VOC,
    SOC, and
    TTHN)
    methods.
    U.S. EPA removed and reserved 40 CFR
    141.24(f) (16) and
    (h)(l2).
    It codified a table of all the
    methods at 40 CFR 141.24(e).
    Most of the updated and new methods
    are from the reference that the Board has termed
    “U.S.
    EPA
    Organic Methods”.
    However, U.S. EPA has continued to use the
    method the Board terms “Dioxin and Furan Method 1613” and added
    two Standard Methods
    (18th ed.) methods:
    Method 6610
    (for
    carbofuran and oxaniyl) and Method 6651
    (for glyphosate).
    U.S.
    EPA further amended 40 CFR 141.24(h) (13) and 141.30(e)
    to refer
    to 40 CFR 141.24(e)
    for methods for the analysis of PCBs and
    TTHN5,
    respectively.
    The Board codified this table of methods at Section 611.645
    and updated the incorporations by reference at Section 611.102
    appropriately.
    We replaced Sections 611.646(p)
    and 611.648(1)
    with statements explaining the U.S. EPA removal of these
    subsections.
    The Board also amended Sections 611.648(m)
    and
    611.685 to refer to Section 611.645 for the methods for PCBs and
    TTHNs.
    By listing the methods for each contaminant in numerical
    order, we deviated from the federal text,
    since we had no
    indication that the federal order indicated a preference among
    the various methods for that species.
    One potential problem may exist with the federal method
    updates at 40 CFR 141.23 and 141.24,
    as well as 141.40.
    U.S. EPA
    appears to be using its reference “Technical Notes on Drinking
    Water Methods” to modify or extend its chosen express regulatory
    language.
    It refers to this document as presenting methods
    available until a certain date
    in the future,
    and it appears to
    refer to this document for either additional methods or for
    further instruction on the use of the methods.
    If U.S. EPA is
    using this as
    a guideline in place of or to supersede its express
    regulatory provisions, this could present codification problems
    for the Board.
    We incorporated certain of the chemical contaminants for
    which there is a state-only requirement
    (an old MCL) into the
    newly-centralized table of methods.
    The added state-only
    22
    contaminants are those for which U.S. EPA did not already set
    forth a method
    (because there is not already a less—stringent
    federal MCL and analytical requirement).
    Those contaminants are
    aldrin,
    DDT, and dieldrin.
    The methods used,
    Methods 505,
    508,
    508.1,
    and 525.2 for aldrin and dieldrin, and 505 and 508 for
    DDT, are those indicated for those contaminants as unregulated
    contaminants
    (aldrin and dieldrin)
    in 40 CFR 141.40(n) (11) or
    those we used in the past based on representations
    in the methods
    that they are capable of determining these contaminants
    (DDT).
    The Board did not make one particular amendment made by U.S.
    EPA.
    U.S.
    EPA removed Appendix C to 40 CFR 141,
    Subpart C at 59
    Fed. Reg.
    62469
    (Dec.
    5,
    1994).
    Inquiry with one of the U.S. EPA
    technical contacts listed in the Federal Register notice
    indicated that this was an error.
    We therefore retained our
    reference to this federal appendix.
    The Board invited comment on our table of updated organic
    analytical methods at Section 611.645.
    The marked-up copy of the
    proposed amendments attached to PC
    2 indicated two corrections.
    The Board has responded by adding method 551 for TTHMs and
    correcting the spelling of “arachlor” in the note.
    U.S. EPA amended the special monitoring provision of Section
    141.40 at 59
    Fed.
    Reg. 34323
    (July 1,
    1994)
    and 59 Fed. Reg.
    62469
    (Dec.
    5,
    1994).
    It updated the methods for the unregulated
    organic contaminants and added aldicarb,
    aldicarb sulfone, and
    aldicarb sulfoxide to the list of unregulated contaminants for
    which it prescribes methods.4
    U.S. EPA updated the existing
    methods and added new methods for the contaminants.
    The methods
    used were from the reference called “U.S.
    EPA Organic Methods” by
    the Board and from Standard Methods
    (18th ed.).
    An additional
    correction in the July 1,
    1994 action replaced the listing for
    the unregulated contaminant chlorobenzene, already regulated as a
    Phase II VOC, with dibromomethane, which U.S. EPA erroneously
    omitted from the table.
    The Board codified the updated organic unregulated
    contaminant analytical methods at Section 611.510(b)(11).
    We
    made the substitution of dibromomethane for chlorobenzene at
    subsection
    (a) (5).
    Based on the July
    1,
    1994 corrections, we
    further substituted “laboratory certified” for “laboratory
    approved” at subsection
    (c).
    Others of the July
    1,
    1994
    corrections resulted in no amendments.
    These federal corrections
    that did not result in amendments included changing “chemicals”
    ~
    U.S. EPA prescribed MCLs for these contaminants as part of
    the Phase IIB rules,
    but subsequently administratively stayed the
    MCL5, without affecting the requirement for monitoring these
    contaminants.
    23
    in the section heading to “contaminants”, which the Board had
    already done; corrections to 40 CFR 141.40(g)
    and (n)(11), which
    were superseded by December
    5,
    1994 amendments; and corrections
    to 40 CFR 141.40(j),
    which pertains to optional monitoring
    requirements that the Board never adopted.
    The Board invited comment on our codification of the methods
    for the organic unregulated contaminant at Section 611.510 and
    received none,
    although we did receive comments from the Agency
    pertaining~to inorganic contaminants, as discussed above.
    Nevertheless, the Board did amend the format for many of the
    methods references for both organic and inorganic contaminants.
    We did this to make the analytical requirements provisions
    consistent throughout the text of the rules.
    Waiver of Cyanide Monitoring Requirements——Sections 611.110
    611.130. and 611.603
    At 59 Fed. Reg.
    34322
    (July
    1,
    1994),
    U.S. EPA added a
    provision to 141.23(c) (2) that allows waivers of the cyanide
    monitoring requirements where there
    is proven no source of
    industrial cyanide to which the supplier’s water is vulnerable.
    This is known as a “use waiver”.5
    The Board added this provision
    for waivers from the cyanide monitoring requirements, choosing
    the now familiar mechanism of the special exception permit
    (SEP)
    to allow the Agency to obviate the requirements.
    However, we did
    not follow the federal structure in placing the waiver provision
    at corresponding Section 611.603(b).
    At Section 611.603(b),
    the Board deviated from the federal
    structure and divided subsection
    (b)
    into two subsections.
    As
    subsection
    (b) (2) the Board stated that the supplier may apply to
    the Agency for a SEP pursuant to subsections
    (d)
    through
    (f)
    and
    Sections 611.110
    (the general SEP provision), stating that the
    supplier must demonstrate that there are no industrial sources on
    cyanide.
    New subsection
    (g) sets forth the language parallel to
    the federal language.
    The Board has reconfigured the Section 611.603(b) (2) and
    611.110(e)
    and
    (g) provisions from their proposed versions in
    response to the Agency’s comments.
    As stated in our proposed
    opinion of March 2,
    1995,
    the federal language of the
    vulnerability waiver lacks definiteness that we believe is
    ~
    A “vulnerability waiver” is available based on consideration
    of such factors as prior monitoring results, how protected the
    source water is from contamination, and treatment plant operations,
    which would tend to show that the water is not vulnerable to
    contamination.
    A “use waiver” is available only where it is shown
    the contaminant was not used in the area.
    24
    necessary to aid suppliers and the Agency in using this relief.
    On the one hand,
    the added sentence at 40 CFR 141.23(c) (2)
    is
    clear that a “use waiver” is intended, but subsections
    (c) (3)
    through
    (c) (8) would also appear to apply to this sentence as
    well as the first sentence, which applies to all other IOCs.
    Subsections
    (c) (3) through
    (c) (8) consider factors other than use
    of the contaminant which are more appropriate considerations for
    “vulnerability waivers”.
    Nevertheless, those subsections also
    contain limitations and mandatory conditions for waivers that
    U.S. EPA may want to apply to the use waivers for cyanide.
    If
    so, the Board would jeopardize state primacy to adopt the cyanide
    waiver provision without also adopting the limitations and
    conditions.
    After reviewing Sections 611.110 and 611.603 in
    light of the Agency’s comments, the Board realized that the
    proposed amendments would have compelled the Agency to consider
    “vulnerability waiver” factors in the context of a request for a
    relief from the cyanide monitoring requirements.
    Based on this,
    the Board adopted amendments that now limit the consideration to
    the lack of any industrial source of cyanide,
    in Section 611.110,
    by limiting consideration to only subsection
    (g).
    We believed
    that limiting consideration to subsection
    (g) was more direct
    than using the Agency—recommended structure of using subsection
    (g)
    to limit consideration to the subsection
    (e) (1)
    “use waiver”
    factor.
    We further left the grant of a cyanide “use waiver”
    subject to all the limitations of subsections
    (c)
    through
    (h).
    One deviation from the federal language warrants further
    discussion,
    in order to avoid any misunderstanding that could
    jeopardize state primacy in the drinking water program.
    The
    Board uses “the Agency shall” where the federal language reads
    “the state may”.
    The Board is compelled to use the imperative
    sense under Illinois administrative law because once the Agency
    has made the necessary determination
    (in this instance, that the
    suppliers water is not vulnerable), the Agency has no discretion
    but to grant the SEP.
    However, this does not mean that the
    Agency is compelled to grant a SEP upon request.
    The Agency
    retains full discretion in making its necessary prerequisite
    determination
    (on vulnerability).
    If the supplier fails to fully
    satisfy the Agency,
    so that it cannot make its determination, the
    Agency is not bound to make the determination.
    The Agency commented on our approach to the cyanide
    monitoring waiver provisions.
    First,
    it noted that the citation
    in Section 611.110(e)
    to the SOC monitoring provisions should
    appear as “611.648(d)”.
    The Board further restructured the
    cyanide monitoring SEP provisions based on our review of the
    proposed text and the Agency’s comments.
    Notice for Exceeding Fluoride Secondary Standard——Section 611.858
    In reviewing the text of the proposed amendments, the Board
    observed one problem created in R93—1,
    July 14,
    1993, when the
    25
    Board deleted Section 611.300(c).
    Section 611.858, which derives
    from 40 CFR 143.3 and 143.5, requires public notification upon
    exceedance of the secondary MCL for fluoride.
    This is the only
    secondary MCL incorporated into the Illinois SDWA regulations
    because it is the only mandatory federal secondary MCL
    requirement.
    That deletion inadvertently left Section 611.858
    incapable of enforcement.
    By substituting the actual secondary
    MCL for fluoride, the Board has corrected that previous error.
    We use the opportunity to update the CFR citation to include
    reference to 40 CFR 143.3, which is the federal source of the
    fluoride secondary NCL.
    Mandatory Health Effects Notices--Section 611.Appendix A
    U.S. EPA made minor corrections of typographic errors to the
    mandatory health effects notices of 40 CFR 141.32(e)
    at 59 Fed.
    Reg. 34323
    (July
    1,
    1994).
    Corrected were the notices for
    chlordane
    (paragraph
    (e) (30)), cis-l, 2—dichloroethylene
    (paragraph
    (e) (33)),
    1, 2-dichloropropane (paragraph
    (e) (35)),
    heptachlor epoxide
    (paragraph
    (e) (41)),
    and di(2-ethylhexyl)
    -
    phthalate (paragraph
    (e) (62)).
    The Board corrected all but one
    of these errors in originally adopting the notices.
    Therefore,
    the Board amends Section 611.Appendix A(62)
    to change “0.004
    parts per million” to “0.006 parts per million”.
    The Board
    invited comment on our correction to the mandatory health effects
    notice for di(2-ethylhexyl)phthalate at Section 611.Appendix
    A(62)
    and received none.
    Public Comment-Based Revisions
    As mentioned above, the Board received several suggestions
    from
    JCAR
    staff,
    the Secretary of State,
    and the Agency for
    corrections to the text of the amendments as proposed.
    The Board
    tabulates the corrections made based on these suggestions as
    follows

    AGENCY OR BOARD ACTION?
    Section 7.2(a)
    (5)
    of
    the
    Act requires the Board to specify
    which decisions U.S. EPA
    will retain.
    In
    addition,
    the
    Board
    is
    to specify
    which State agency
    is to make decisions
    based
    on
    the
    general division of functions within the Act and
    other
    Illinois
    statutes.
    In situations where the Board has determined that U.S. EPA
    will retain decision-making authority, the Board has replaced
    “Regional Administrator” with U.S. EPA,
    so as to avoid specifying
    which
    office
    within
    U.S.
    EPA
    is
    to
    make
    a
    decision.
    In
    a
    few
    instances,
    decisions
    are
    not appropriate for Agency
    action
    pursuant
    to
    a
    permit
    application.
    Among
    the
    considerations
    in
    determining
    the
    general
    division
    of
    authority
    between
    the
    Agency
    and
    the
    Board
    are:
    1.
    Is the person making the decision applying a Board
    regulation, or taking action contrary to
    (“waiving”) a Board
    regulation?
    It
    generally
    takes
    some
    form
    of
    Board
    action
    to
    “waive”
    a Board regulation.
    2.
    Is there a clear standard for action such that the
    Board
    can
    give
    meaningful
    review
    to
    an Agency decision?
    37
    3.
    Does the action result
    in exemption from the permit
    requirement
    itself?
    If
    so,
    Board
    action
    is
    generally
    required.
    4.
    Does
    the
    decision
    amount
    to
    “determining,
    defining
    or
    implementing environmental control standards” within the
    meaning of Section 5(b)
    of the Act?
    If so,
    it must be made
    by the Board.
    There are four common classes of Board decision:
    variance,
    adjusted standard, site specific rulemaking,
    and enforcement.
    The first three are methods by which a regulation can be
    temporarily postponed (variance)
    or adjusted to meet specific
    situations (adjusted standard or site specific rulemaking).
    Note
    that there often are differences in the nomenclature for these
    decisions between the U.S. EPA and Board regulations.
    EDITORIAL CONVENTIONS
    As a final note,
    the federal rules have been edited to
    establish a uniform usage throughout the Board’s regulations.
    For example, with respect to “shall”,
    “will”, and “may”,
    “shall”
    is used when the subject of a sentence has to do something;
    “must” is used when someone has to do something,
    but that someone
    is not the subject of the sentence;
    “will” is used when the Board
    obliges itself to do something,
    and “may”
    is used when choice of
    a provision is optional.
    As to the conjunctions,
    “or”
    is used
    rather than “and/or”, and denotes “one or both”; “either
    or” denotes “one
    but
    not
    both”;
    and
    “and”
    denotes
    “both”.
    ORDER
    The
    Board
    will
    promptly
    submit
    these
    adopted amendments to
    the
    Secretary
    of
    State
    for

    ILCS 51 that the Board adopt
    regulations which are identical
    in substance with federal
    regulations promulgated by the United States Environmental
    Protection Agency (U~S~EPA)pursuant to Sections 1412(b),
    1414(c),
    1417(a)
    and 1445(a)
    of the Safe Drinking Water Act
    (SDWA)
    (42 U.S.C.
    300f
    et seq.)
    b)
    This Part establishes primary drinking water regulations (NPDWRs)
    pursuant to the SDWA,
    and also includes additional, related State
    requirements which are consistent with and more stringent than the
    U~S~EPAregulations
    (Section 7.2(a)(6)
    of the Act).
    The latter
    provisions are specifically marked as “additional State
    requirements”.
    They apply only community water systems
    (CWSB).
    c)
    This Part applies to
    “suppliers”, owners and operators of “public
    water systems” (PWSS”).
    PWSs include CWSs,
    “non—community water
    systems
    (“non—CWSs’) and
    “non—transient non—community water
    systems (“NTNCWSs”),
    as these terms are defined in Section
    611.101.
    1)
    CWS suppliers are required to obtain permits from the
    Illinois Environmental Protection Agency (Agency)
    pursuant
    to 35
    Ill. Adm. Code
    602.
    2)
    Non—CWS suppliers are subject to additional regulations
    promulgated by the Illinois Department of Public Health
    (Public Health)
    pursuant to
    Ill.

    including 77
    Ill. Adm.
    Code
    900.
    3)
    NOn—CWS suppliers are not required to obtain permits or
    other approvals from the Agency,
    or to file reports or other
    documents with the Agency.
    Any provision
    in
    this Part
    so
    providing
    is to be understood as requiring the non—CWS
    supplier to obtain the comparable form of approval from,
    or
    to file the comparable report or other document with Public
    Health.
    BOARD NOTE:
    Derived from 40 CFR 141.1
    (19e94).
    d)
    This Part applies to each PWS, unless the PWS meets all of the
    following conditions:
    1)
    Consists only of distribution and storage facilities
    (and
    does not have any collection and treatment facilities);
    2)
    Obtains all of
    its water from,
    but is
    not owned or operated
    by,
    a supplier to which such regulations apply;
    3)
    Does not sell water to any person;
    and
    42
    4)
    Is not a carrier which conveys passengers in interstate
    commerce.
    BOARD NOTE:
    Derived from 40 CFR 141.3

    Special Exception Permits
    a)
    Unless otherwise specified,
    each Agency determination
    in this Part
    is to be made by way of a written permit pursuant to Section 39(a)
    of the Act.
    Such permit
    is titled a “special exception” permit
    (“SEP”).
    b)
    No person shall cause or allow the violation of any condition of
    a
    SEP.
    c)
    The supplier may appeal the denial of or the conditions of a SEP
    to the Board pursuant to Section 40 of the Act.
    d)
    A SEP may be initiated either:
    1)
    By an application filed by the supplier; or
    2)
    By the Agency,
    when authorized by Board regulations.
    BOARD NOTE:
    The Board does not intend to mandate by any
    provision
    of this Part that the Agency exercise
    its
    discretion and initiate a SEP pursuant to subsection (d)(2)
    above.
    Rather,
    the Board intends to clarify by this
    subsection
    that
    the
    Agency
    may
    opt
    to
    initiate
    a
    SEP
    without
    receiving
    a

    BOARD
    NOTE:
    The Agency shall grant a SEP from the Section 611.603

    subsection
    (g)
    below,
    not on the basis of this subsection.
    1)
    If the Agency determines that there was no prior use of the
    contaminant,
    it shall grant the SEP,
    or
    68
    2)
    If the contaminant was previously used or the previous use
    was unknown, the Agency shall consider the
    following
    factors:
    A)
    Previous analytical results;
    B)
    The
    proximity
    of
    the
    system
    to
    any
    possible
    point
    source
    of

    or
    non—point
    source
    of
    contamination (including the use of pesticides and

    D)
    How well the water source
    is protected against
    contamination, including whether
    it
    is
    a SWS or
    a GWS:
    i)
    A GWS must consider well depth,
    soil type, well
    casing integrity, and wellhead protection;
    and
    ii)
    A SWS must consider watershed protection;
    and
    E)
    For Phase
    II,
    Phase IIB,
    and Phase V SOC5 and
    unregulated organic contaminants
    (pursuant to Section
    611.631 or 611.648):
    i)
    Elevated nitrate levels at the water source; and
    ii)
    The use of PCB5 in equipment used in the
    production,
    storage,
    or distribution
    of water
    (including pumps,
    transformers, etc.);
    and
    F)
    For Phase
    I,
    Phase II,
    and Phase V VOC5
    (pursuant to
    Section 611.646):
    the number of persons served by the
    PWS and the proximity of
    a smaller system to
    a larger
    one.
    f)
    If
    a supplier refuses to provide any necessary additional
    information requested by the Agency, or
    if
    a supplier delivers any
    necessary information
    late
    in the Agency’s deliberations on
    a
    request,
    the Agency may deny the requested SEP or grant the SEP
    with conditions within the time allowed by
    law.
    gJ.
    The Agency shall grant
    a supplier
    a SEP that
    allows
    it to
    discontinue monitoring for cyanide if
    it determines that the
    supplier’s water
    is not vulnerable due to
    a lack of any industrial
    source
    of
    cyanide.

    Section
    1415
    Variances
    This Section
    is
    intended as a State equivalent of Section 14l5(a)(l)(A)
    of the
    SDWA.
    a)
    The Board may grant
    a supplier a variance from
    a
    NPDWR
    in
    this
    Part.
    1)
    The supplier shall file
    a variance petition pursuant to 35
    Ill. Adm.
    Code
    104,
    except as modified or supplemented by
    this
    Section.
    2)
    The Board may grant
    a variance from the additional State
    requirements
    in this Part without following this Section.
    b)
    As part of the showing of arbitrary or unreasonable hardship,
    the
    supplier shall demonstrate that:
    1)
    Because of characteristics of the raw water sources that are
    reasonably available to the system,
    the supplier cannot meet
    the MCL or other requirement; and
    2)
    The system has applied BAT as identified in Subpart G of
    this Part.
    BAT may vary depending on:
    A)
    The number of persons served by the system;
    B)
    Physical conditions related to engineering
    feasibility;
    and
    C)
    Costs of compliance; and
    3)
    The variance will not result in an unreasonable risk to
    health,
    as defined in subsection
    (g) below.
    c)
    The Board will prescribe a schedule
    for:
    1)
    Compliance,
    including increments of progress,
    by the
    supplier,
    with each
    MCI. or other requirement with respect to
    which the variance was granted,
    and
    2)
    Implementation by the supplier of each additional control
    measure for each MCI. or other requirement, during the period
    ending
    on
    the
    date
    compliance
    with
    such
    requirement
    is
    required.
    d)
    A
    schedule
    of
    compliance
    will
    require
    compliance
    with
    each
    MCL
    or
    other
    requirement
    with
    respect
    to
    which
    the
    variance
    was
    granted
    as expeditiously as practicable.
    e)
    The Board will provide notice and opportunity for
    a public hearing
    as provided
    in
    35
    Ill.
    Adm. Code 104.
    f)
    The Board will not grant
    a variance:
    1)
    From the MCL for total
    coliforms; provided, however, that
    the Board may grant a variance from the total coliform MCL
    70
    of Section 611.325 for PWSS that demonstrate that the
    violation of the total coliform MCL is due to persistent
    growth of total coliforms
    in the distribution system,
    rather
    than from fecal or pathogenic contamination, from a
    treatment lapse or deficiency, or from
    a problem in the
    operation or maintenance of the distribution system.
    2)
    Or,
    from any of the treatment technique requirements of
    Subpart
    B
    of
    this
    Part.
    g)
    As used in this
    Section and Section 611.112,
    “unreasonable risk to
    health level”
    (“URTH level”) means the concentration of
    a
    contaminant that will cause a serious health effect within the
    period of time specified
    in the variance or exemption requested by
    a supplier seeking to come into compliance by installing the
    treatment required to reduce the contaminant to the MCL.
    URTH
    level determinations are made on the basis of the individual
    contaminant,
    taking into account:
    the degree by which the
    level
    exceeds the
    MCI.; duration of exposure; historical data;
    and
    population
    exposed.
    A
    risk
    to
    health
    is
    assumed
    to
    be
    unreasonable unless the supplier demonstrates that there are costs
    involved that clearly exceed the health benefits to be derived.
    h)
    The
    provisions of Section 611.130 apply to determinations made
    pursuant to this Section.

    a variance
    from any requirement
    respecting
    an
    MCI.
    or
    treatment
    technique
    requirement
    of
    an
    NPDWR
    in
    this
    Part.
    1)
    The supplier shall file
    a variance petition pursuant to 35
    Ill.
    Adm.
    Code
    104,
    except
    as modified or supplemented by
    this Section.
    2)
    The Board may grant a variance from the additional State
    requirements
    in this Part without
    following this Section.
    b)
    As part of the showing of
    arbitrary or unreasonable hardship,
    the
    supplier shall demonstrate that:
    1)
    Due to compelling factors
    (which may
    include economic
    factors),
    the supplier
    is unable to comply with the MCL or
    treatment technique requirement;
    2)
    The supplier was:
    A)
    In operation on the effective date of the
    MCI. or
    treatment technique
    requirement;
    or
    71
    B)
    Not
    in operation on the effective date of the MCL or

    supplier;
    and
    3)
    The variance will not result
    in an unreasonable risk to
    health,
    c)
    The
    Board
    will
    prescribe
    a
    schedule
    for:
    1)
    Compliance,
    including increments of progress,
    by the
    supplier, with each MCL and treatment technique requirement
    with respect to which the variance was granted; and
    2)
    Implementation by the supplier,
    during the period ending on
    the date when compliance
    is required,
    of each additional
    control measure for each contaminant subject to the MCL or
    treatment technique requirement.
    d)
    A schedule of
    compliance will require compliance with each
    MCI. or
    other
    requirement
    with
    respect
    to
    which
    the
    variance
    was
    granted
    as expeditiously as practicable;
    but no schedule shall extend more
    than
    12 months after the date of the variance,
    except as
    follows:
    1)
    The Board may extend the date for
    a period not to exceed
    three years beyond the date of the variance
    if the supplier
    establishes:
    that
    it
    is
    taking all practicable steps to
    meet the standard;
    and:
    A)
    The supplier cannot meet the standard without capital
    improvements that cannot be completed within
    12
    months;
    B)
    In the case of
    a supplier that needs financial
    assistance for the necessary improvements,
    the
    supplier has entered into an agreement to obtain such
    financial assistance;
    or
    C)
    The supplier has entered into an enforceable agreement
    to become a part of
    a regional PWS; and
    2)
    In the case of
    a PWS with
    500 or fewer service connections
    that needs financial assistance for the necessary
    improvements,
    a variance under subsections
    (d)(1)(A)
    or
    (d)(1)(B)
    above may be renewed for one or more additional
    two year periods if the supplier establishes that it
    is
    taking all practicable steps to meet the final date for
    compliance.
    e)
    The Board will provide notice and opportunity for
    a public hearing
    as
    provided
    in
    35
    Ill.

    72
    1)
    From the MCL for total coliforms; provided,
    however,
    that
    the Board may grant a variance
    from the total coliform MCL
    of Section
    611.325
    for PWSs that demonstrate that the
    violation of the total coliform MCL is due to persistent
    growth of total coliforms in the distribution system,
    rather
    than from fecal or pathogenic contamination,
    from a
    treatment lapse or deficiency,
    or
    from a problem in the

    BOARD
    NOTE:
    This
    is an additional State requirement.
    Section 611.130
    Special Requirements for Certain Variances and Adjusted
    Standards
    a)
    Relief
    from the TTHM MCL.
    1)
    In granting any variance or adjusted standard to a supplier
    that
    is
    a CWS that adds
    a disinfectant at any part of
    treatment and which provides water to 10,000 or more persons
    on a regular basis from the maximum contaminant level
    for
    TTHM listed
    in Section 611.310(c), the Board will require
    application of
    the best available technology
    (BAT)
    identified at Bubsection
    (a)(4) below for that constituent
    as
    a condition to the relief,
    unless the supplier has
    demonstrated through comprehensive engineering assessments
    that
    application
    of
    BAT
    is
    not
    technically
    appropriate
    and
    technically feasible for that system,
    or
    it would only
    result
    in
    a
    marginal
    reduction
    in
    TTHM
    for
    that
    supplier.
    2)
    The Board will require the following as
    a condition for
    relief from the TTHM
    MCI. where
    it does not require the
    application of BAT:
    A)
    That the supplier continue to investigate the
    following methods as an alternative means of
    significantly reducing the level of TTHM,
    according to
    a definite schedule:
    i)
    introduction of off—line water storage for
    THM
    precursor reduction;
    ii)
    aeration for TTHM reduction,
    where geography and
    climate allow;
    iii)
    introduction of clarification, where not
    presently practiced;
    iv)
    use of alternative sources of raw water;
    and
    v)
    use of ozone as an alternative or supplemental
    disinfectant
    or oxidant,
    and
    B)
    That the supplier report results of that investigation
    to the Agency.
    3)
    The Agency shall petition the Board to reconsider or modify
    a variance or adjusted standard,
    pursuant to 35 Ill.
    Adm.
    Code 101.Subpart
    K,
    if
    it determines that an alternative
    method
    identified
    by
    the
    supplier
    pursuant
    to
    subsection
    (a)(2)
    above
    is technically feasible and would result
    in
    a
    significant reduction
    in TTHM.
    74
    4)
    Best available technology for TTHM reduction:
    A)
    use of chloramines
    as an alternative or supplemental
    disinfectant,
    B)
    use of chlorine dioxide
    as an alternative or
    supplemental disinfectant,
    or
    C)
    improved existing clarification for THM precursor
    reduction.
    BOARD NOTE:
    Derived from 40 CFR 142.60
    (1992.4).
    The
    restrictions of this subsection do not apply to
    suppliers regulated for TTHM as
    an additional state
    requirement.
    See the Board Note to Section
    611.301(c).
    b)
    Relief from the fluoride MCL.
    1)
    In granting any variance or adjusted standard to
    a Bupplier
    that
    is
    a CWS
    from the maximum contaminant level for
    fluoride
    listed in Section 611.301(b),
    the Board will
    require application of the best available technology
    (BAT)
    identified at
    subsection
    (b) (4) below for that constituent
    as
    a
    condition
    to
    the
    relief,
    unless
    the
    supplier
    has
    demonstrated through comprehensive engineering assessments
    that application of BAT
    is not technically appropriate and
    technically feasible for that supplier.
    2)
    The Board will require the following as
    a condition for
    relief
    from the fluoride
    MCI. where it does not require the
    application of
    BAT:
    A)
    That the supplier continue to investigate the
    following methods as an alternative means of
    significantly reducing the level
    of TTHM,
    according to
    a definite schedule:
    i)
    modification of lime softening;
    ii)
    alum coagulation;
    iii)
    electrodialysis;
    iv)
    anion exchange resins;
    v)
    well field management;
    vi)
    use
    of
    alternative
    sources
    of
    raw
    water;
    and
    vii)
    regionalization,
    and
    B)
    That the supplier report results of that investigation
    to the Agency.
    3)
    The Agency shall petition the Board to reconsider or modify
    a variance or
    adjusted standard, pursuant to 35
    Ill.
    Adm.
    Code 101.Subpart K,
    if
    it determines that an alternative
    method identified by the supplier pursuant to subsection
    (b)(2)
    above
    is technically feasible and would result
    in
    a
    significant reduction in fluoride.
    75
    4)
    Best available technology for fluoride reduction:
    A)
    activated alumina absorption centrally applied,
    and
    B)
    reverse osmosis centrally applied.
    BOARD NOTE:
    Derived from 40 CFR 142.61
    (1992.4).
    C)
    Relief from an inorganic chemical contaminant, VOC,
    or SOC MCL.
    1)
    In granting to
    a supplier that
    is
    a CWS or NTNCWS any
    variance or adjusted standard from the maximum contaminant
    levels for any VOC or
    SOC,
    listed in Section 611.311(a)
    or
    (C),
    or
    for any inorganic chemical contaminant,
    listed in
    Section 611.301,
    the supplier must have first applied the
    best available technology
    (BAT)
    identified at Section
    611.311(b)
    (VOCs and SOC5) or Section 611.301(c)
    (inorganic
    chemical contaminants)
    for that constituent, unless the
    supplier has demonstrated through comprehensive engineering
    assessments that application of BAT would achieve only a
    minimal and insignificant reduction in the level of
    contaminant.
    BOARD NOTE:
    U.S. EPA lists BAT for each SOC and VOC at
    40
    CFR 142.62(a)
    (19924),
    as amended at
    57 Fed.
    Rcg.
    31848
    (July
    17,
    1092)-,
    for the purposes of variances and
    exemptions
    (adjusted
    standards).
    That
    list
    is
    identical
    to
    the list
    at 40 CFR 141.61(b), with three exceptions:
    the
    section 142.62 listing adds PTA
    (“PAT”)
    for alachlor;
    lists
    OX
    for hexachlorobenzene,
    instead of GAC; and omits PTA for
    toxaphene.
    The Board has chosen to use the section
    141.61(a)
    (Section 611.311) BAT listing because we believe
    UCEPA intcndcdthat this
    leads to greater consistency and
    because the preamble at
    57 Fed.
    flag.
    31778
    79
    indicates
    that
    this
    listing is correct as to alachlor and hoxachlorobenzcnc
    (although the preamble at
    56 Fed.
    Reg.
    3529
    (Jan.
    30,
    1991)
    indicates that
    it
    iD wrong as to toxaphcne).
    2)
    The Board may require any of the following as a condition
    for relief
    from a MCL listed in Section 611.301 or 611.311:
    A)
    That the supplier continue to investigate alternative
    means of compliance according to a definite schedule,
    and
    B)
    That the supplier report results of that investigation
    to the Agency.
    3)
    The Agency shall petition the Board to reconsider or modify
    a variance or adjusted standard, pursuant to 35
    Ill.
    Adm.
    Code 101.Subpart K,
    if it determines that an alternative
    method identified by the supplier pursuant to subsection
    (c)(2)
    above is technically feasible.
    BOARD
    NOTE:
    Derived from 40 CFR 142.62(a)
    through
    (e)
    (1992~4).
    d)
    Conditions requiring use of bottled water or point—of—use or
    point—of—entry devices.
    In granting any variance or adjusted
    standard from the maximum contaminant levels
    for organic and
    inorganic chemicals or an adjusted standard from the treatment
    technique for lead and copper,
    the Board may impose certain
    76
    conditions requiring the use of bottled water,
    point—of—entry
    devices,
    or point—of—use devices to avoid an unreasonable risk to
    health,
    limited as provided in subsections
    (e) and
    (f) below.
    1)
    Relief from an MCI..
    The Board may, when granting any
    variance or adjusted standard from the MCL requirements of
    Sections 611.301 and 611.311,
    impose
    a condition that
    requires
    a supplier to use bottled water, point—of—use
    devices, point—of—entry devices or other means to avoid an
    unreasonable risk to health.
    2)
    Relief from corrosion control treatment.
    The Board may,
    when granting an adjusted standard from the corrosion
    control treatment
    requirements for lead and copper of
    Sections
    611.351 and 611.352,
    impose a condition that
    requires
    a supplier to use bottled water and point—of—use
    devices or other means,
    but not point—of—entry devices, to
    avoid an unreasonable risk to health.
    3)
    Relief from source water treatment or service line
    replacement.
    The Board may, when granting an exemption from
    the source water treatment and lead service line replacement
    requirements
    for
    lead
    and
    copper
    under
    Sections
    611.353
    or
    611.354,
    impose
    a condition that requires
    a supplier to use
    point—of-entry devices to avoid an unreasonable risk to
    health.
    BOARD NOTE:
    Derived
    from 40 CFR 142.62(f)
    (1992.4).
    e)
    Use of bottled water.
    Suppliers that propose to use or use
    bottled water as
    a condition for receiving
    a variance or an
    adjusted standard from the requirements of Section 611.301 or
    Section 611.311, or an adjusted standard from the requirements of
    Sections 611.351 through 611.354 must meet the requirements of
    either subsections
    (e)(1),
    (e)(2),
    (e)(3),
    and
    (e)(6)
    or
    (e)(4),

    and (e)(6)
    below:
    1)
    The supplier must develop
    a monitoring program for Board
    approval that provides reasonable assurances that the
    bottled water meets all
    MCLs of Sections 611.301 and 611,311
    and submit
    a description of this program as part of its
    petition.
    The proposed program must describe how the
    supplier will
    comply with each requirement of this
    subsection.
    2)
    The supplier must monitor representative samples of the
    bottled water
    for all contaminants regulated under Sections
    611.301 and 611.311 during the first three—month period that
    it supplies the bottled water to the public, and annually
    thereafter.
    3)
    The supplier
    shall annually provide the results of the
    monitoring program to the Agency.
    4)
    The supplier must receive
    a certification from the bottled
    water company as to each of the following:
    A)
    that the bottled water supplied has been taken from an
    approved source of bottled water,
    as such
    is defined
    in Section 611.101;
    77
    B)
    that the approved source of bottled water has

    6)
    The 8upplier shall assure the provision
    of sufficient
    quantities of bottled water to every affected person
    supplied by the supplier via door—to—door bottled water
    delivery.
    Derived from 40 CFR 142.62(g)
    (19924).
    f)
    Use of point—of—entry devices.
    Before the Board grants any PWS a
    variance or adjusted standard from any NPDWR that includes a
    condition requiring the use of
    a point—of—entry device,
    the
    supplier must demonstrate
    to the Board each of the following:
    1)
    that the supplier will operate and maintain the device;
    2)
    that the device provides health protection equivalent to
    that provided by central treatment;
    3)
    that the supplier will maintain the microbiological safety
    of the water at
    all times;
    4)
    that the supplier has established standards for performance,
    conducted
    a rigorous engineering design review, and field
    tested the device;
    5)
    that the operation and maintenance
    of the device will
    account for any potential for increased concentrations of
    heterotrophic bacteria resulting through the use of
    activated carbon, by backwashing, post—contactor
    disinfection,
    and heterotrophic plate count monitoring;
    6)
    that buildings connected to the supplier’s distribution
    system have sufficient devices properly
    installed,
    maintained,
    and monitored to assure that all consumers are
    protected;
    and
    7)
    that the use of the device will not cause increased
    corrosion of lead and copper bearing materials located
    between the device and the tap that could increase
    contaminant levels at the tap.

    Section 611.212
    Groundwater under Direct
    Influence of Surface Water
    The Agency shall, pursuant to Section 611.201, require all CWS8 to demonstrate
    whether
    they are using “groundwater under the direct influence of surface
    water”
    by
    June
    29,
    1994.
    The
    Agency
    shall
    determine with information provided
    by the supplier whether a PWS uses “groundwater under the direct influence of
    surface water” on an individual basis.
    The Agency shall determine that a
    groundwater source
    is under the direct
    influence of surface water based upon:
    a)
    Physical characteristics of the source:
    whether the source is
    obviously
    a surface water source,
    such as
    a lake or
    stream.
    Other
    sources which may be subject to influence from surface waters
    include:
    springs,
    infiltration galleries, wells or other
    collectors
    in
    subsurface
    aquifers.
    b)
    Well
    construction characteristics and geology with field
    evaluation.
    1)
    The Agency may use the wellhead protection program’s
    requirements, which include delineation of wellhead
    protection areas,
    assessment of sources of contamination and
    implementation of management control systems,
    to determine
    if the welihead is under the influence of
    surface water.
    2)
    Wells less than or equal to 50 feet
    in depth are likely to
    be under the influence of surface water.
    3)
    Wells greater than 50 feet
    in depth are likely to be under
    the influence of surface water, unless they include:
    A)
    A surface sanitary seal using bentonite clay,
    concrete
    similar material,
    B)
    A well casing that penetrates consolidated
    (slowly
    permeable)
    material,
    and
    C)
    A well casing that
    is only perforated or screened
    beLow consolidated (slowly permeable) material.
    4)
    A source which is less than 200 feet from any surface water
    is
    likely to be under the influence of surface water.
    c)
    Any structural modifications to prevent the direct influence of
    surface water and eliminate the potential
    for Giardia lamblia cyst
    contamination.
    d)
    Source water quality records.
    The following are indicative that a
    source
    is under the influence of
    surface water:
    1)
    A
    record
    of
    total
    coliform
    or
    fecal
    coliform
    contamination
    in untreated samples collected over the past three years,
    2)
    A history of turbidity problems associated with the source,
    or
    79
    3)
    A history of known or suspected outbreaks of Giardia lamblia
    or other pathogenic organism associated with surface water
    (e.g.
    cryptosporidium), which has been attributed to that
    source.
    0)
    Significant and relatively rapid shifts in water characteristics
    such as turbidity, temperature,
    conductivity or pH.
    1)
    A variation in turbity of 0.5 NTU or more over one year is
    indicative of surface influence.
    2)
    A variation in temperature of
    9 Fahrenheit degrees or more
    over one year
    is indicative of surface influence.
    f)
    Significant and relatively rapid shifts
    in water characteristics
    such as turbidity,
    temperature,
    conductivity or pH which closely
    correlate
    to
    clirnatological
    or
    surface
    water
    conditions
    are
    indicative of
    surface water influence.
    1)
    Evidence of particulate matter associated with the surface
    water.
    or,
    2)
    Turbidity or temperature data which correlates to that of
    a
    nearby water source.
    g)
    Particulate analysis:
    Significant occurance of insects or other
    macroorganisms,
    algae or large diameter pathogens such as Giardia
    lamblia is indicative of surface influence.
    1)
    “Large
    diameter”
    particulates
    are
    those
    over
    7
    micrometers.
    2)
    Particulates must be measured as
    specified in the “Guidance
    Manual for Compliance with the Filtration and Disinfection
    Requirements
    for Public Water Systems using Surface Water
    Sources”,
    incorporated by reference
    in Section 611.102.
    h)
    The potential for contamination by small—diameter pathogens,
    such
    as bacteria or viruses, does not alone render the source “under
    the direct influence of surface water”.

    General Requirements
    a)
    The requirements of this Subpart constitute NPDWRs.
    This Subpart
    establishes criteria under which filtration
    is required as a
    treatment technique for PWS5 supplied by a surface water source
    and PWS5 supplied by
    a groundwater source under the direct
    influence
    of
    surface
    water.
    In
    addition,
    these
    regulations
    establish treatment technique requirements
    in lieu of MCLs for the
    following contaminants:
    Giardia lamblia,
    viruses, HPC bacteria,
    Legionella and turbidity.
    Each supplier with a surface water
    source or a groundwater source under the direct influence of
    surface water shall provide treatment
    of that source water that
    complies with these treatment technique requirements.
    The
    80
    treatment technique requirements consist of installing and
    properly operating water treatment processes which reliably
    achieve:
    1)
    At least 99.9 percent
    (3—log)
    removal or inactivation of
    Giardia lamblia cysts between
    a point where the raw water is
    not subject to recontamination by surface water runoff and a
    point downstream before or
    at the first customer;
    and
    2)
    At
    least 99.99 percent
    (4—log)
    removal or inactivation of
    viruses between a point where the raw water is not subject
    to recontamination by surface water runoff and a point
    downstream before or at the first customer.
    b)
    A
    supplier using a surface water
    source or a groundwater source
    under the direct influence of surface water
    is considered to be in
    compliance with the requirements
    of subsection
    (a)
    if:
    1)
    It
    meets the requirements
    for avoiding filtration in
    Sections
    611.230
    through
    611.232
    and
    the
    disinfection
    requirements in Section 611.241; or
    2)
    It meets the filtration requirements
    in Section 611.250 and
    the disinfection requirements
    in Section 611.242.
    C)
    Each supplier using a
    surface water source or
    a groundwater source
    under the direct influence of surface water shall have a certified

    Compliance with old MCLs
    for inorganic chemicals
    is calculated pursuant to Section 611.612,.

    BOARD NOTE:
    Derived from 40 CFR 141.11(b)
    &
    (c)
    (1992.4).
    This provision, which corresponds with 40 CFR 141.11, was
    formerly the only
    listing of MCL5 for inorganic parameters.
    However, U.S~.EPAadded another listing of inorganic MCLs at
    40 CFR 141.62 at
    56 Fed.
    Reg. 3594
    (Jan.
    30,
    1991).
    Following the changing U~.S. EPA codification scheme creates
    two listings
    of MCLs:
    one at this Section and one at
    Section 611.301.
    This causes fluoride to appear in both the
    40 CFR 141.11(b)
    and 141.62(b)
    listings with the same
    MCI..
    The Board has deleted the corresponding fluoride MCL from
    this Section in favor of that which appears at Section
    611.301(b).
    UCEPA adopted a
    tICL for cyanide at 40
    CFII
    141.62(b)(13), effective January 17,
    1994,
    at
    57 Fed. Reg.
    31847
    (July
    17,
    1992).
    That ~tCLis the same as that at this
    Section.
    The Board has rendered the state MCL at this
    Section ineffective
    on the date the new federal HCL becomes
    effective.
    c)
    This subsection corresponds with
    40 CFR 141.11(c),
    the substance
    of which the Board has codified in subsection
    (b)
    above.
    This
    statement maintains structural parity with the
    federal rules.
    d)
    Nitrate.
    1)
    The Board incorporates by reference 40 CFR 141.11(d)
    (1992.4).
    This incorporation includes no later editions or
    amendments.
    2)
    Non-CWS5 may exceed the
    MCI. for nitrate under the following
    circumstances:
    A)
    The nitrate
    level must not exceed 20 mg/L,
    B)
    The water must not be available to children under six
    months of age,
    C)
    There will be continuous posting of the fact that the
    nitrate level exceeds
    10 mg/L together with the public
    health effects information set forth in paragraph
    (2)
    of Section Gll.Appendix
    A,
    D)
    The supplier will annually notify local public health
    authorities and Public Health of the nitrate
    levels
    that exceed
    10
    mg/I.,
    and
    E)
    No adverse public health effects
    result.
    BOARD NOTE:
    Derived from 40 CFR 141.11(d)
    (1992.4).
    Public Health regulations may impose a nitrate
    limitation requirement.
    Those regulations are at 77
    Ill.
    Adm. Code 900.50.
    e)
    The following supplementary condition applies to the MCL5 listed
    in subsection
    (b) above
    for iron and manganese:
    82
    1)
    CWS suppliers that serve
    a population of 1000 or less,
    or
    300 service connections
    or less,
    are exempt
    from the
    standards
    for iron and manganese.
    2)
    The
    Agency may, by special exception permit, allow iron and
    manganese
    in excess of the MCI. if
    sequestration tried on an
    experimental basis proves to be effective.
    If sequestration
    is not effective, positive
    iron or manganese reduction
    treatment
    as applicable must be provided.
    Experimental use
    of
    a sequestering agent may be tried only if approved by

    Section 611.325
    Microbiological Contaminants
    a)
    The
    MCI. is based on the presence or absence of total coliforms in
    a sample,
    rather than coliform density.
    1)
    For
    a supplier which collects at
    least 40 samples per month,
    if no more than 5.0 percent
    of the samples collected during
    a month are total coliform—positive,
    the supplier
    is
    in
    compliance with the MCL for total coliforms.
    2)
    For
    a supplier which collects fewer than 40 samples per
    month,
    if no more than one sample collected during
    a month
    is total coliform-positive,
    the supplier
    is in compliance
    with the MCL for total coliforms,
    b)
    Any fecal coliform-positive repeat sample or E. coli—positive
    repeat
    sample, or any total coliform-positive repeat sample
    following a fecal coliform—positive or
    E. coli—positive routine
    88
    sample,
    constitutes a violation of the MCI. for total coliforms.
    For
    purposes of the public notification requirements
    in Section
    611.851 et seq., this
    is
    a violation that may pose an acute risk
    to health.
    C)
    A supplier shall determine compliance with the
    MCI. for total
    coliforrns in subsections
    (a)
    and
    (b)
    for each month in which
    it
    is
    required to monitor for total coliforms.

    Protection of wells from contamination by coliforms by
    appropriate placement and construction;
    2)
    Maintenance of RDC throughout the distribution system;
    3)
    Proper maintenance of the distribution system including
    appropriate pipe replacement and repair procedures,
    main
    flushing programs,
    proper operation and maintenance of
    storage tanks and reservoirs and continual maintenance of
    positive water pressure in all parts of the distribution

    SUBPART G:
    LEAD AND COPPER
    Section 611.350
    General Requirements
    a)
    Applicability and Scope
    1)
    Applicability.
    The requirements of this Subpart constitute
    national primary drinking water regulations
    for lead and
    copper.
    This Subpart applies to all community water systems
    (CWS5)
    and non—transient, non—community water systems
    (NTNCWS5).
    2)
    Scope.
    This Subpart establishes a treatment technique that
    includes requirements for corrosion control treatment,
    source water treatment,
    lead service line replacement,
    and
    public education.
    These requirements are triggered,
    in some
    cases, by lead and copper action levels measured in samples
    collected at consumers’
    taps.
    b)
    Definitions.
    For the purposes of only this Subpart,
    the following
    terms shall have the
    following meanings:
    “Action
    level” means that concentration of
    lead or copper
    in
    water computed pursuant to subsection
    (c) below that
    determines,
    in some cases, the treatment requirements
    of
    90
    confusion with “compliance period”,
    as used elsewhere in
    this Part and defined
    at Section 611.101.
    “Multiple—family residence” means
    a building that is
    currently used as
    a multiple—family residence,
    but not one
    that
    is also
    a “single—family structure”.
    “90th percentile level” means that concentration of lead or
    copper contaminant exceeded by 10 percent or
    fewer of all
    samples collected during a six—month monitoring period
    pursuant to Section 611.356
    (i.e., that concentration of
    contaminant greater than or equal
    to the results obtained
    from 90 percent of the samples).
    The 90th percentile levels
    for copper and lead shall be determined pursuant to
    subsection
    (c)(3)
    below.
    BOARD NOTE:
    Derived from
    40 CFR 141.80(e)
    (1992.4).
    “Optimal corrosion control treatment” means the corrosion
    control treatment that minimizes the lead and copper
    concentrations at users’ taps while ensuring that the
    treatment does not cause the water system to violate any
    national primary drinking water regulations.
    “Practical quantitation limit” or “PQL” means the lowest
    concentration of a contaminant that
    a well—operated
    laboratory can reliably achieve within specified limits of
    precision
    and
    accuracy
    during
    routine
    laboratory
    operating
    conditions.
    The PQL
    for lead
    is 0.005 mg/I..
    The PQL for
    copper
    is 0.050 mg/I..
    BOARD NOTE:
    Derived from 40 CFR 141.89(a)(1)(ii)
    and
    (a)(1)(iv)

    Beg.
    26511—12
    (June
    7,
    1991)
    (orcamble).

    Lead and Copper Action Levels:
    1)
    The lead action level
    is exceeded
    if the 90th percentile
    lead level is greater than 0.015 mg/I..
    2)
    The copper action level
    is exceeded if the 90th percentile
    copper level
    is greater than 1.3 mg/L.
    3)
    Suppliers shall compute the 90th percentile lead and copper
    levels
    as follows:
    A)
    List the results of
    all lead or copper samples taken
    during a six—month monitoring period in ascending
    order,
    ranging from the sample with the lowest
    concentration first to the sample with the highest
    91
    concentration last.
    Assign each sampling result
    a
    number, ascending by single integers beginning with
    the number
    1 for the sample with the lowest
    contaminant
    level.
    The number assigned to the sample
    with the highest contaminant level shall be equal to
    the total number of samples taken.
    B)
    Determine the number for the 90th percentile sample by
    multiplying the total number of samples taken during
    the six—month monitoring period by 0.9.
    C)
    The contaminant concentration
    in the
    sample with the
    number yielded by the calculation in subsection
    (c)(3)(B)
    above
    is the 90th percentile contaminant
    level.
    D)
    For suppliers that collect
    5 samples per six—month
    monitoring period,
    the 90th percentile
    is computed by
    taking the average of the highest and second highest
    concentrations.

    (b)(2), or (b)(3)
    below,
    b)
    Suppliers deemed to have optimized corrosion control.
    A supplier
    is deemed
    to have optimized corrosion control, and
    is not required
    to complete the applicable corrosion control treatment steps
    identified in this Section,
    if the supplier satisfies one of the
    following criteria:
    1)
    Small or medium—sized system meeting action levels.
    A small
    system or medium—sized system supplier
    is deemed to have
    optimized corrosion control
    if the system meets the lead and
    copper action levels during each of two consecutive six—
    month monitoring periods with monitoring conducted in
    accordance with Section 611.356.
    2)
    SEP
    for equivalent activities to corrosion control.
    The
    Agency shall, by
    a SEP granted pursuant to Section
    611.110,
    deem any supplier to have optimized corrosion control
    treatment
    if
    it determines that the supplier has conducted
    activities equivalent to the corrosion control steps
    applicable
    under
    this
    Section.
    In
    making
    this
    determination,
    the Agency shall specify the water quality
    control parameters
    representing optimal corrosion control in
    accordance with Section 611.352(f).
    A supplier shall
    provide the Agency with the following information
    in order
    to support an Agency SEP determination under this
    subsection:
    A)
    the results of all test
    samples collected for each of
    the water quality parameters
    in Section 611.352(c) (3);
    B)
    a report explaining the test methods the supplier used
    to evaluate the corrosion control treatments Listed in
    Section 611.352(c)(),
    the results of all tests
    93
    conducted,
    and the basis
    for the supplier’s selection
    of optimal corrosion control treatment;
    C)
    a report explaining how the supplier has installed
    corrosion control and how the supplier maintains
    it to
    insure minimal lead and copper concentrations at
    consumers’
    taps;
    and
    D)
    the results
    of tap water samples collected in
    accordance with Section 611.356 at
    least once every
    six months
    for one year after corrosion control has
    been installed.
    3)
    Results less than practical quantitation level
    for lead.
    Any supplier is
    deemed to have optimized corrosion control
    if
    it submits results of tap water monitoring conducted in
    accordance with Section 611.356 and source water monitoring
    conducted in accordance with Section 611.358 that
    demonstrate that for two consecutive six—month monitoring
    periods the difference between the 90th percentile tap water
    lead level, computed pursuant to Section 611.350(c) (3),
    and
    the highest source water lead concentration
    is
    less than the
    practical quantitation level
    for lead specified
    in Section
    611.359(a) (1) (B) (i)
    c)
    Suppliers not required to complete corrosion control steps for
    having met both action levels.
    1)
    Any small system or medium—sized system supplier,
    otherwise
    required to complete the corrosion control steps due to its
    exceedance of the lead or copper action
    level, may cease
    completing the treatment steps after the supplier has
    fulfilled both of the following conditions:
    A)
    It has met both the copper action level and the lead
    action
    leveL during each of two consecutive six—month
    monitoring periods conducted pursuant to Section
    611.356,
    and
    B)
    the supplier has submitted the results
    for those two
    consecutive six—month monitoring periods to the
    Agency.
    2)
    A supplier that has ceased completing the corrosion control
    steps pursuant to subsection (c)(1) above (or the Agency,
    if
    appropriate)
    shall
    resume
    completion
    of
    the
    applicable
    treatment steps,
    beginning with the first treatment step
    that the supplier previously did not complete in its
    entirety,
    if
    the
    supplier
    thereafter
    exceeds
    the
    lead
    or
    copper action level during any monitoring period.
    3)
    The Agency may, by
    SEP, require a supplier to repeat
    treatment steps previously completed by the supplier where
    it determines that this
    is necessary to properly implement
    the treatment requirements of this Section.
    Any such SEP
    shall explain the basis for this decision.
    4.).
    The requirement
    for any small or medium—sized system
    supplier to implement corrosion control treatment steps
    in
    accordance with subsection

    Lead Service Line Replacement
    a)
    Suppliers required to replace lead service lines.
    1)
    If the results from tap samples taken pursuant to Section
    611.356(d) (2) exceed the
    lead action level after the
    supplier has installed corrosion control or source water
    treatment (whichever sampling occurs later),
    the supplier
    shall recommence replacing lead service
    lines in accordance
    with the requirements of subsection
    (b) below.
    96
    2)
    If
    a supplier is
    in violation of Section 611.351 or Section
    611.353 for
    failure to install source water or corrosion
    control treatment, the Agency may,
    by a SEP issued pursuant
    to Section 611.110,
    require the supplier to commence lead
    service line replacement under this Section after the date
    by which the supplier was required to conduct monitoring
    under Section 6l1.356(d)(2)
    has passed.
    b)
    Annual replacement of lead service lines.
    1)
    A supplier required to commence lead service line
    replacement pursuant to subsection
    (a)
    above shall annually
    replace at
    least
    7 percent of the initial number of lead
    service lines
    in its distribution system.
    2)
    The initial number of lead service lines is the number of
    lead lines in place at the time the replacement program
    begins.
    3)
    The supplier shall identify the initial number of lead
    service lines
    in
    its distribution system based on a
    materials evaluation,
    including the evaluation required
    under Section 611.356(a).
    4)
    The first year of lead service line replacement shall begin
    on the date the supplier exceeded the action
    level
    in tap
    sampling referenced in subsection
    (a)
    above.
    c)
    Service lines not needing replacement.
    A supplier
    is not required
    to replace any individual lead service line for which the lead
    concentrations in all service line samples taken from that line
    pursuant to Section 611.356(b)(3)
    are less than or equal to 0.015
    mg/I..
    d)
    Replacement
    of service line.
    1)
    A
    supplier required to replace
    a lead service line pursuant
    to subsection
    (a)
    above shall replace the entire service
    line (up to the building
    inlet) unless the Agency determines
    pursuant to subsection
    (e) below that the supplier controls
    less than the entire service line.
    2)
    Replacement of
    less than the entire
    service line.
    A)
    Where the Agency has determined that the supplier
    controls less than the entire
    service line, the
    supplier shall replace that portion of the line that
    the Agency determines
    is under the supplier’s control.
    B)
    The supplier that will replace less than the entire
    service line shall notify the user served by the line
    that the supplier will replace that portion of the
    service line under its control,
    and the supplier shall
    offer to replace the remaining portion of the service
    line that
    is under the building owner’s control.
    C)
    The supplier required to replace less than the entire
    service line is not required to bear the cost of
    replacing any portion of the service line that
    is
    under the building owner’s control.
    D)
    Offer to collect samples.
    97
    i)
    For buildings where only a portion of the lead
    service line
    is replaced, the supplier shall
    inform the resident(s) that the supplier will
    collect
    a first draw tap water sample after
    partial
    replacement
    of
    the
    service
    line
    is
    completed
    if the resident(s)
    so desire.
    ii)
    In eases where the resident(s)
    accept the offer,
    the supplier shall collect the sample and report
    the results to the resident(s)
    within 14 days
    following partial
    lead service line replacement.
    e)
    Control of entire service line.
    1)
    A supplier is presumed to control the entire lead service
    line (up to the building inlet) unless the supplier
    demonstrates to the satisfaction of the Agency, in
    a letter
    submitted under Section 611.360(e) (4),
    that it does not have
    any of the following forms of control over the entire line
    (as defined by state statutes, municipal ordinances,
    public

    BOARD
    NOTE:
    See
    Section
    611.360(e)(4)
    and
    the
    Board
    Note that follows.
    The court
    in American Water Works
    Association v.
    EPA, 40 F.3d 1266
    (D.C.
    Cir.
    1994),
    vacated U.S.
    EPA’s definition of
    “control” to the
    extent
    it would require the supplier to exert
    “control” over
    a privately—owned service connection.
    The Board does
    not intend that the Illinois definition
    give the State regulations more effect than the
    federal definition gives the U.S. EPA regulations.
    f)
    Agency determination of shorter replacement schedule.
    1)
    The
    Agency shall, by
    a SEP issued pursuant to Section
    611.110, require
    a supplier to replace
    lead service lines on
    a shorter schedule than that otherwise required by this
    98
    Section
    if
    it determines,
    taking into account the number of
    lead service lines
    in the system, that such a shorter
    replacement
    schedule is feasible.
    2)
    The Agency shall notify the supplier of
    its
    finding pursuant
    to subsection
    (f)(1)
    above within
    6 months after the
    supplier
    is triggered into lead service line replacement
    based on monitoring,
    as referenced in subsection
    (a)
    above.
    g)
    Cessation of service Line replacement.
    1)
    Any supplier may cease replacing lead service
    lines whenever
    it fulfills both of the following conditions:
    A)
    first draw tap samples collected pursuant to Section
    611.356(b) (2)
    meet the
    lead action level during each
    of two consecutive six—month monitoring periods and
    B)
    the supplier has submitted those results to the
    Agency.
    2)
    If any of the supplier’s first draw tap samples thereafter
    exceed the lead action level, the supplier shall recommence
    replacing lead service Lines pursuant to subsection
    (b)
    above.
    h)
    To demonstrate compliance with subsections
    (a) through
    (d)
    above,
    a supplier shall report to the Agency the information specified in
    Section
    611.360(e).

    Section 611.357
    Monitoring for Water Quality Parameters
    All large
    system suppliers, and
    all
    small and medium—sized system suppliers
    that exceed the lead action
    level or the copper action level,
    shall monitor
    water
    quality
    parameters in addition to lead and copper
    in accordance with
    this Section.
    The requirements
    of this Section are summarized
    in Section
    611.Table
    G.
    a)
    General Requirements
    1)
    Sample collection methods
    A)
    Use of tap samples.
    The totality of all tap samples
    collected by a supplier shall be representative of
    water quality throughout the distribution system
    taking into account the number of persons served,
    the
    different sources of water,
    the different treatment
    methods employed by the supplier,
    and
    seasonal
    variability.
    Although
    a supplier may conveniently
    conduct tap sampling for water quality parameters at
    sites
    used
    for
    coliform
    sampling
    performed
    pursuant
    to
    Subpart
    I. of this Part,
    it
    is not required to do
    so,
    and a supplier
    is not required to perform tap sampling
    pursuant to this Section at taps targeted
    for lead and
    copper sampling under Section 611.356(a).
    B)

    Each supplier shall
    collect samples
    at entry point(s) to the distribution
    99
    system from locations representative of each source
    after treatment.
    If
    a supplier draws water from more
    than one source and the sources are combined before
    distribution, the supplier must sample at an entry
    point to the distribution system during periods of
    normal operating conditions
    (i.e., when water is
    representative
    of
    all
    sources
    being
    used).
    2)
    Number of samples
    A)
    Tap samples.

    3)
    Confirmation sampling.
    A)
    A supplier may take a confirmation sample for any
    water quality parameter value no later than 3 days
    after
    it
    took
    the
    original
    sample
    it
    seeks
    to
    confirm.
    B)
    If a supplier takes
    a confirmation sample,
    it must
    average the result obtained from the confirmation
    sample with the result obtained from the original
    sample it seeks to confirm,
    and the supplier shall use
    the average of these two results for any compliance
    determinations under Section 611.352(g).
    C)
    The Agency shall delete the results that
    it determines
    are due to obvious sampling errors
    from this
    calculation.
    e)
    Reduced monitoring.
    1)
    Reduction in tap monitoring.
    A supplier that has maintained
    the range of values for the water quality parameters

    rebut the presumption that
    it has control over the entire
    lead service line pursuant to Section 611.354(d)
    shall
    submit
    a letter to the Agency describing the following:
    A)
    the legal authority
    (e.g.,
    state statutes,
    municipal
    ordinances,
    public service contracts or other
    applicable legal
    authority) that limits the supplier’s
    control over the service lines;
    and
    B)
    the extent of the supplier’s control over the service
    lines.
    BOARD NOTE:
    This communication
    is vital to a supplier
    seeking to replace less than entire service lines.
    Under Section 6l1.354(e)(1),
    a supplier
    is presumed to
    control the entire service line unless
    it makes an
    affirmative showing.
    Under Section 611.354(d)(2)(A),
    a supplier
    is affirmatively required to replace all of
    each service line except
    as to any particular service
    line for which the Agency has made an affirmative
    determination that the supplier does not control in
    110
    its entirety.
    Under Sections
    611.354(b)(1)
    and
    (b)(4),
    the supplier must have completed replacing
    seven percent of the lead service Lines within
    a year
    of the day of the event that triggered the
    requirement.
    Section 39(a)
    of the Act allows the
    Agency 90 days to render its decision on any permit
    request.
    Therefore,
    any supplier that desires an
    Agency determination pursuant to Section 611.354(e) (2)
    must submit the required infomation within the three
    month time—frame of this subsection.
    f)
    Reporting for public education program.
    1)
    By December 31st of each calendar year,
    any supplier that
    is
    subject to the public education requirements of Section
    611.355 shall
    submit
    a letter to the Agency demonstrating
    that the supplier has delivered the public education
    materials which meet the following requirements:
    A)
    the content requirements of Section 611.355(a)
    and
    (b),
    and
    B)
    the delivery requirements of Section 611.355(c).
    2)
    The information submitted pursuant to this subsection shall
    include
    a list of all the newspapers,
    radio stations,
    television
    stations,
    facilities and organizations to which
    the supplier delivered public education materials during the
    previous year.
    3)
    The supplier shall submit the letter required by this
    subsection annually for as
    long as
    it continues to exceed
    the lead action level.
    g)
    Reporting 9jadditional monitoring data.
    Any supplier that
    collects sampling data in addition to that required by this
    Subpart shall report the results of that sampling to the Agency e~
    or bcforcwithin the first ten days following the end of the
    applicable sampling period(s)
    specified by Sections 611.356
    through 611.358 during which the samples are collected.

    Monitoring for
    Phase V unregulated contaminants.
    Monitoring of
    the unregulated organic contaminants listed
    in subsection
    (b)(11)
    below and the unregulated inorganic contaminants listed in
    subsection
    (b)(12)
    below shall be conducted
    as follows:
    1)
    Each CWS and NTNCWS supplier shall take four consecutive
    quarterly samples
    at each sampling point
    for each
    contaminant
    listed in subsection
    (b)(11)
    below and report
    the results to the Agency.
    Monitoring must be completed by
    December
    31,
    1995.
    2)
    Each CWS and NTNCWS supplier shall take one sample at each
    sampling point for each contaminant listed in subsection
    (b)(12) below and report the results to the Agency.
    Monitoring must be completed by December
    31,
    1995.
    3)
    Each CWS and NTNCWS supplier may apply to the Agency for a
    SEP pursuant to Section 611.110 that releases
    it from any of
    the requirements of
    subsections
    (b)(1)
    and
    (b)(2)
    above.
    4)
    The Agency shall grant
    a SEP pursuant to Section 611.110 as
    follows:
    A)
    From any requirement of subsection
    (b)(1)
    above based
    on consideration of the factors set
    forth at Section
    611.110(e),
    and
    B)
    From any requirement of subsection
    (b)(2) above
    if
    previous analytical results indicate contamination
    would not occur,
    provided this data was collected
    after January
    1,
    1990.
    5)
    A GWS supplier shall take a minimum
    of one sample at every
    entry point to the distribution system that is
    representative of each well after treatment (“sampling
    point”).
    6)
    A SWS or mixed system supplier shall take a minimum of one
    sample at points
    in the distribution system that are
    representative of each source or at each entry point to the
    system after treatment
    (“sampling point”).
    7)
    If the system draws water from more than one source and
    sources are combined before distribution, the supplier shall
    sample at an entry point during periods of normal operating
    conditions
    (when water representative of all sources
    is
    being
    used).
    8)
    The Agency may issue a SEP pursuant to Section
    610.110 to
    require a supplier to use a confirmation sample for results
    that
    it finds dubious for whatever reason.
    The Agency must
    state its reasons
    for
    issuing the SEP if the SEP
    is Agency-
    initiated.
    114
    9)
    Suppliers shall take samples at the same sampling point
    unless the Agency has granted a SEP allowing another
    sampling point because conditions make another sampling
    point more representative of the water from each source or
    treatment plant.
    BOARD NOTE:
    Subsection
    (b)(9)
    above corresponds with
    duplicate segments of 40 CFR l41.40(n)(5)
    and
    (n)(6)
    (1992-4),
    which correspond with subsections
    (b)(5)
    and
    (b)(6)
    above.
    The Board has adopted no counterpart to 40 CFR
    141.40(n) (9),
    an optional provision that pertains to
    composite sampling.
    Otherwise,
    the structure of this
    Section directly corresponds with 40 CFR 141.40(n)
    (1992-i).
    10)
    Instead of performing the monitoring required by this
    subsection,
    a CWS and NTNCWS
    supplier serving fewer than 150
    service connections may send a letter to the Agency stating
    that the PWS
    is available
    for sampling.
    This
    letter must be
    sent to the Agency by January
    1,
    1994.
    The supplier shall
    not send such samples to the Agency,
    unless requested to do
    so by the Agency.

    I.:
    MICROBIOLOGICAL MONITORING
    AND ANALYTICAL REQUIREMENTS
    Section 611.522
    Repeat Coliform Monitoring
    a)
    If
    a routine
    sample is total coliform—positive,
    the supplier shall
    collect
    a set of repeat samples within 24 hours of being notified
    of the positive result.
    A supplier that collects more than one
    routine sample per month shall collect no
    fewer than three
    repeat
    samples
    for each total coliform—positive sample found.
    A supplier
    that collects one routine sample per month or fewer shall collect
    no fewer than four repeat samples
    for each total coliform-positive
    sample found.
    The Agency shall extend the 24—hour limit on a
    case-by—case basis
    if it determines that the supplier has a
    logistical problem
    in collecting the repeat
    samples within 24
    hours that is beyond
    its control.
    In the ease of an extension,
    the Agency shall specify how much time the supplier has to collect
    the repeat samples.
    b)
    The supplier shall collect at least one repeat
    sample from the
    sampling tap where the original total coliforrn-positive sample was
    taken,
    and at
    least one repeat sample
    at
    a tap within five service
    connections upstream and
    at
    least one repeat sample at a tap
    within five service connections downstream of the original
    sampling site.
    If
    a total coliform—positive sample
    is at the end
    of the distribution system,
    or one away from the end of the
    distribution system,
    the Agency may waive the requirement to
    collect
    at least one repeat
    sample upstream or downstream of the
    original sampling site.
    c)
    The supplier shall collect all repeat samples on the same day,
    except that the Agency shall allow
    a supplier with
    a single
    service connection to collect the required set of repeat
    samples
    over a four—day period or to collect
    a larger volume repeat
    sample(s)
    in one or more sample containers of any size,
    as long as
    the total volume collected
    is at least 400 ml
    (300 ml for PWSs
    that collect more than one routine sample per month).
    d)
    If one or more repeat samples
    in the
    set is total coliform—
    positive,
    the supplier shall collect an additional set of repeat
    samples
    in the manner specified
    in subsections
    (a) through
    (c).
    The additional
    samples must be collected within 24 hours of being
    116
    notified of the positive result, unless the Agency extends the
    limit as provided in subsection
    (a).
    The supplier shall repeat
    this process until either total coliforms are not
    detected in one
    complete set of repeat samples
    or the supplier determines that the
    MCI. for total coliforms in Section 611.325 has been exceeded and
    notifies the Agency.
    e)
    If
    a supplier collecting fewer than five routine samples/month has
    one or more total coliform—positive samples and the Agency does
    not invalidate the sample(s) under Section 611.523, the supplier
    shall collect at least
    five routine samples during the next month
    the supplier provides water to the public,
    unless the Agency
    determines that the conditions of subsection (e)(1)
    or
    (2)
    are
    met.
    This does not apply to the requirement to collect repeat
    samples
    in subsections
    (a)
    through
    (d).
    The supplier does not
    have to collect the samples
    if:
    1)
    The Agency performs a site visit before the end of the next
    month the supplier provides water to the public.
    Although
    a
    sanitary survey need not be performed,
    the site visit must
    be sufficiently detailed to allow the Agency to determine
    whether additional monitoring or any corrective action is
    needed.
    2)
    The Agency has determined why the sample was total coliform-
    positive and establishes that the supplier has corrected the
    problem or will correct the problem before the end of the
    next month the supplier serves water to the public.
    A)
    The Agency shall document this decision
    in writing,
    and make the document available to U.S. EPA and the
    public.
    The written documentation must describe the
    specific cause of the total coliform—positive sample
    and what action the supplier has taken or will take to
    correct the problem.
    B)
    The Agency cannot waive the requirement to collect
    five routine samples the next month the supplier
    provides water to the public solely on the grounds
    that all repeat
    samples are total coliform—negative.
    C)
    Under this subsection,
    a supplier shall still take at
    least one routine sample before the end of the next
    month it
    serves water to the public and use it
    to
    determine compliance with the MCI. for total coliforms
    in Section 611.325, unless the Agency has determined
    that the supplier has corrected the contamination
    problem before the supplier took the set of repeat
    samples required in subsections
    (a) through
    (d),
    and
    all repeat samples were total
    coliforrn—negative.
    f)
    After a supplier collects a routine sample and before
    it
    learns
    the results of
    the analysis of that
    sample,
    if
    it collects another
    routine sample(s)
    from within five adjacent service connections of
    the initial sample,
    and the initial sample,
    after analysis,
    is
    found to contain total coliforms,
    then the supplier may count the
    subsequent sample(s)
    as a repeat sample instead of as a routine
    sample.
    g)
    Results of all routine and repeat samples not invalidated pursuant
    to Section 611.523 must be included
    in determining compliance with
    the
    MCI. for total coliforms
    in Section 6l1.32S~

    Section 611.523
    Invalidation of Total CoLiform Samples
    A total coliform—positive sample invalidated under this Section does not count
    towards meeting the minimum monitoring requirements.
    a)
    The Agency shall
    invalidate a total coliform—positive sample only
    if the conditions
    of subsection
    (a)(1),
    (a)(2),
    or
    (a)(3) are met.
    1)
    The laboratory establishes that improper sample analysis
    caused the total coliform—positive result.
    2)
    The Agency,
    on the basis of the results of repeat samples
    collected as required by Section 611.522(a) through
    (d)
    determines that the total coliform—positive sample resulted
    from a domestic or other non-distribution system plumbing
    problem.
    The Agency cannot invalidate a sample on the basis
    of repeat
    sample results unless all repeat sample(s)
    collected at the same tap as the original total coliform—
    positive sample are also total coliform—positive, and all
    repeat samples collected within five service connections of
    the original tap are total coliform—negative
    (e.g., Agency
    cannot invalidate
    a total coliform—positive sample on the
    basis
    of repeat samples
    if
    all the repeat samples are total
    coliform—negative,
    or
    if the supplier has only one service
    connection).
    3)
    The Agency determines that there are substantial grounds to
    believe that
    a total coliform—positive result is due to a
    circumstance or condition which does not reflect water
    quality in the distribution system.
    In this case,
    the
    supplier shall still collect all repeat samples required
    under Section 611.522(a) through
    (d) and use them to
    determine compliance with the MCL for total coliforms in
    Section 611.325.
    To invalidate a total coliform-positive
    sample under this subsection, the decision with the
    rationale for the decision must be documented
    in writing.
    The Agency shall make thia document available to U.S. EPA
    and the public.
    The written documentation must state the
    specific cause of the total coliform—positive sample,
    and
    what action the supplier has taken, or will take,
    to correct
    this problem.
    The Agency shall not invalidate a total
    coliforni-positive sample solely on the grounds that all
    repeat samples are total coliform—negative.
    b)
    A laboratory shall invalidate
    a total coliform sample
    (unless
    total coliforms are detected)
    if the sample produces
    a turbid
    culture
    in the absence of gas production using an analytical
    method where gas formation
    is examined
    (e.g., the Multiple—Tube
    Fermentation Technique), produces
    a tqrbid culture
    in the absence
    of an acid reaction
    in the P—A Coliform Test,
    or exhibits
    confluent growth or produces colonies too numerous to count with
    an analytical method using
    a membrane filter
    (e.g., Membrane
    Filter Technique).
    If
    a laboratory invalidates a sample because
    of such
    interference,
    the supplier shall collect another sample
    from the same
    location as the original sample within 24
    hours of
    being notified of the interference problem,
    and have it analyzed
    for the presence of total coliforms.
    The supplier shall continue
    to re—sample within 24 hours and have the samples analyzed until
    118
    it obtains
    a valid result.
    The
    Agency shall waive the 24—hour
    time limit on a case—by—case basis,
    if
    it
    is not possible to
    collect the sample within that time.

    in accordance with
    the following procedure:
    1)
    When the MTF Technique or P-A Coliform Test
    is used to test
    for total
    coliforms,
    shake the lactose—positive presumptive
    tube or P—A vigorously and transfer the growth with a
    sterile
    3—mm
    loop or sterile applicator stick into brilliant
    green lactose bile broth and EC medium, defined below, to
    determine the presence of total and
    fecal coliforms,
    respectively.
    2)
    For Microbiological Mapproved methods,
    referenced above,
    that use a membrane filter, transfer the total coliform—
    positive culture by one of the following methods:
    remove
    the membrane containing the total eoLiform colonies
    from the
    substrate with a sterile forceps and carefully curl and
    insert the membrane into a tube of EC medium.
    (The
    laboratory may first remove a small portion of selected
    colonies
    for verification);
    swab the entire membrane filter
    surface with
    a sterile cotton swab and transfer the inoculum
    to EC medium (do not
    leave the cotton swab
    in the EC
    medium);
    or inoculate
    individual total coliform—positive
    colonies
    into EC medium.
    Gently shake the inoculated tubes
    of EC medium to
    insure adequate mixing and incubate in a
    waterbath at 44.5±0.2°C

    Suppliers need only determine the presence or absence of
    fecal coliforms,
    a determination of feeal coliform density
    is not required.
    f)
    Suppliers
    shall conduct analysis of E. coli
    in accordance with one
    of the following analytical methods:
    1)
    EC medium supplemented with 50
    pg/I. of MUG
    (final
    concentration).
    EC medium is
    as described in subsection
    (e).
    MUG may be added to EC medium before autoclaving.
    EC
    medium supplemented with 50
    pg/I. MUG
    is commercially
    available.
    At least
    10 niL of EC medium supplemented with
    MUG must be used.
    The inner inverted fermentation tube may
    be omitted.
    The procedure for transferring a total
    coliform-positive culture to EC medium supplemented with MUG
    is
    as
    in subsection
    (e)
    for transferring
    a total coliform—
    positive culture to EC medium.
    Observe fluorescence with an
    ultraviolet
    light (366 nm)
    in the dark after incubating tube
    at 44.5±2°
    C
    for 24±2hours;
    or
    2)
    Nutrient agar supplemented with 100 pg/I. MUG
    (final
    concentration).
    Nutrient Agar
    is described in Standard
    Methods,

    Method 908C9221
    B,
    at pages 9—47
    to
    9-

    This test is used to determine
    if
    a total coliform—
    positive sample,
    as determined by the MF technique or any
    other method in which
    a membrane filter
    is used,
    contains E.
    coli.
    Transfer the membrane
    filter containing
    a total
    coliform colony or colonies to nutrient agar supplemented
    with 100
    pg/I. MUG
    (final concentration).
    After incubating
    the agar plate at 35°Celsius for
    4 hours,
    observe the
    colony or colonies under ultraviolet
    light
    (366 nm)
    in the
    dark for fluorescence.
    If
    fluorescence is visible,
    E.
    coli
    are present.

    as
    set forth in
    Section 61l.Appendix

    (The Autoanalysis Coliert System is
    a MMO-MUG test.)
    If the MMO—MUG test
    is total coliform
    positive after
    a 24-hour
    incubation, test the medium for
    fluorescence with a 366—nm ultraviolet light (preferably
    with a 6—watt lamp)
    in the dark.
    If fluorescence
    is
    observed,
    the sample
    is E.
    coli—positive.
    If fluorescence
    is questionable
    (cannot be definitiveLy read)
    after 24 hours
    incubation,
    incubate the culture
    for an additional
    four
    hours
    (but not to exceed 28 hours total),
    and again test the
    medium for fluorescence.
    The MMO-MUG test with hepes buffer
    is the only approved formulation for the detection of
    E.
    coli.

    Section 611.601
    Monitoring
    Frequency
    Monitoring shall be conducted as follows:
    a)
    Required sampling.
    1)
    Each supplier shall take a minimum of one sample at each
    sampling point at the times required by Section 611.610
    beginning in the initial compliance period.
    2)
    Each sampling point must produce samples that are
    representative of the water from each source after treatment
    or from each treatment
    plant,
    as required by subsection
    (b)
    below.
    The
    total
    number
    of
    sampling
    points
    must
    be
    representative of the water deLivered to users throughout
    the PWS.
    3)
    The supplier shall take each sample at the same sampling
    point unless conditions make another sampling point more
    representative of each source or treatment plant and the
    Agency
    has
    granted
    a
    SEP
    pursuant
    to
    subsection
    (b)(5)
    below.
    b)
    Sampling
    points.
    1)
    Sampling points
    for GWSs.
    Unless otherwise provided by SEP,
    a GWS supplier shall take at
    least one sample from each of
    the
    following
    points:
    each
    entry
    point
    that
    is
    representative of each well after treatment.
    2)
    Sampling points
    for SWS5 and mixed systems.
    Unless
    otherwise provided by SEP,
    a SWS
    or mixed system supplier
    shall take at least one sample from each of the
    following
    points:
    A)
    Each entry point after the application of treatment;
    or
    B)
    A point
    in
    the
    distribution
    system
    that
    is
    representative of each source after treatment.
    3)
    If a system draws water from more than one source,
    and the
    sources are combined before distribution, the supplier shall
    sample at an entry point during periods of normal operating
    conditions when water
    is representative of all
    sources being
    used.
    4)
    Additional
    sampling points.
    The
    Agency shall,
    by SEP,
    designate additional sampling points
    in the distribution
    system or at the consumer’s tap if
    it determines that such
    samples are necessary to more accurately determine consumer
    exposure.
    5)
    Alternative sampling points.
    The Agency shall,
    by SEP,
    approve alternate sampling points
    if the supplier
    demonstrates that the points are more representative than
    the
    generally
    required
    point.
    C)
    This subsection corresponds with 40 CFR 141.23(a)(4),
    an optional
    U~.S~.EPAprovision relating to compositing of samples that
    U~,S.,
    EPA does not require for state programs.
    This statement maintains
    structural consistency with U~S~EPArules.
    129
    d)
    The frequency of monitoring for the following contaminants must be
    in accordance with the following Sections:
    1)
    Asbestos:

    compliance with the MCL5 for antimony,
    asbestos, barium,
    beryllium,
    cadmium,
    chromium,
    cyanide,
    fluoride, mercury,
    nickel,
    selenium, ac~4orthallium is determined by
    a running annual average
    at each sampling point.
    133
    1)
    If the
    average at any sampling point
    is greater than the
    MCL,
    then
    the
    supplier
    is
    out
    of
    compliance.
    2)
    If
    any one sample would cause the annual
    average to be
    exceeded,
    then the supplier
    is out of compliance
    immediately.
    3)
    Any sample below the method detection limit must be
    calculated at
    zero for the purpose of determining the annual
    average.
    BOARD
    NOTE:
    The “method detection limit”
    is different from
    the “detection limit”,
    as set forth
    in
    Section
    611.600.
    The
    “method detection limit”
    is the level of contaminant that
    can be determined by
    a particular method with
    a 95 percent
    degree
    of
    confidence,
    as
    determined
    by
    the
    method
    outlined
    in 40 CFR 136, appendix
    B,
    incorporated by reference at
    Section 611.102.
    b)
    For
    suppliers that monitor annually or
    less
    frequently,
    compliance
    with the McLs for antimony,
    asbestos,
    barium, beryllium,
    cadmium,
    chromium,
    cyanide,
    fluoride,
    mercury,
    nickel,
    selenium, ef~d~
    thallium is determined by the level
    of the contaminant
    at any
    sampling point.
    If
    a confirmation sample is
    taken, the
    determination of
    compliance will be based on the average of the
    two samples.
    C)
    Compliance with the MCLs for nitrate and nitrite
    is determined
    based on one sample if the
    levels of these contaminants are below
    the MCI.s.
    If the levels
    of nitrate or nitrite exceed the MCL5
    in
    the initial sample,
    Section 611.606 requires confirmation
    sampling, and compliance
    is determined based on
    the average of the
    initial
    and confirmation samples.
    d)
    When the portion of the distribution
    system that
    is out of
    compliance
    is
    separable
    from
    other
    parts
    of
    the
    distribution
    system
    and
    has
    no
    interconnections,
    the
    supplier
    may
    give
    the
    public notice required by Subpart T only to persons served by that
    portion of the
    distribution system not in compliance.

    ________
    effective
    a)
    Analyses for the purpose of determining compliance with the old
    inorganic MCLs of Section 611.300 are required as follows:
    1)
    Analyses for
    all CWSs utilizing surface water sources must
    be repeated at yearly intervals.
    2)
    Analyses for all
    CWSs utilizing only groundwater sources
    must be repeated at three—year intervals.
    3)
    This
    subsection corresponds with 40 CFR l41.23(l)(3)
    (19934), which
    requires monitoring for the
    repealed old MCL
    for nitrate at a frequency specified by the state.
    The
    Board has followed the U.S. EPA lead and repealed that old
    MCL.
    This
    statement maintains structural consistency with
    U.S. EPA rules.
    4)
    This
    subsection corresponds with 40 CFR l41.23(l)(4)
    (19934), which authorizes the state to determine compliance
    and
    initiate enforcement action.
    This authority exists
    through the authorization of the Act,
    not through federal
    rules.
    This statement maintains structural consistency with
    U.S. EPA rules.
    b)
    If the result of
    an analysis made under subsection
    (a)
    above
    indicates that
    the
    level
    of
    any
    contaminant
    listed
    in
    Section
    611.300 exceeds the old MCL, the supplier shall report to the
    Agency
    within
    7 days and initiate three additional analyses at the
    same sampling point
    within one month.
    c)
    When the
    average
    of
    four
    analyses
    made

    a
    frequency
    designated
    by
    the
    Agency
    by
    a
    SEP granted pursuant to Section 611.110 and must continue until
    the old MCL has not been exceeded in two
    successive
    samples
    or
    until a different monitoring schedule becomes effective as
    a
    condition to a
    variance,
    an adjusted standard,
    a site specific
    rule,
    an enforcement action,
    or another SEP granted pursuant to
    Section
    611.110.
    d)
    This subsection corresponds with 40
    CFR
    141.23(o)
    (199~4),
    which
    pertains to monitoring
    for the repealed old MCL for nitrate.
    The
    Board has followed the U.S. EPA action and repealed that old
    MCL.
    This statement maintains structural consistency with U.S. EPA
    rules.
    e)
    This subsection corresponds with
    40 CFR l41.23(p)
    (19934), which
    pertains to the use of existing data up until
    a date long since
    expired.

    Special Monitoring for Sodium
    a)
    CWS suppliers shall collect
    and analyze one sample per plant at
    the entry point of the distribution system for the determination
    of sodium concentration levels;
    samples must be collected and
    analyzed annually for CWSs utilizing surface water sources in
    whole or
    in part, and
    at
    least every three years for CWSs
    utilizing solely groundwater sources.
    The minimum number of
    samples required to be taken by the supplier
    is based on the
    number of treatment plants used by the supplier,
    except that
    multiple wells drawing raw water from a single aquifer may, with
    the Agency
    approval, be considered one treatment plant for
    determining the minimum number of samples. The Agency shall
    require the supplier to collect
    and analyze water samples for
    sodium more frequently in locations where the sodium content
    is
    variable.
    b)
    The CWS supplier shall report to the Agency the results of the
    analyses for sodium within the first
    10 days of the month
    following the month
    in which the sample results were received or
    within the first
    10 days following the end of the required
    monitoring period as
    specified by
    SEP, whichever of these
    is
    first.
    If more than annual sampling
    is required the supplier shall
    report the average sodium concentration within
    10 days of the
    month following the month
    in which the analytical results of the
    last sample used for the annual average was received.
    c)
    The CWS supplier shall notify the Agency and appropriate local
    public health officials of the sodium levels by written notice by
    direct mail within three months.
    A copy of each notice required to
    be provided by this subsection must be sent to the Agency within
    10 days of its
    issuance.

    “Detect” and “detection” means that the contaminant of
    interest is present at
    a level greater than or equal to the
    “detection limit”.
    “Detection limit” means 0.0005 mg/L.
    BOARD
    NOTE:
    Derived from 40 CFR l41.24(f)(7),
    (f)(11),
    (f)(14)(i), and (f)(2O)
    (19934).
    This
    is
    a “trigger
    level”
    for Phase
    I,
    Phase
    II,
    and Phase V VOC5 inasmuch as
    it
    prompts further action.
    The use of the term “detect” in
    this section
    is not intended to include any analytical
    capability of quantifying lower levels of any contaminant,
    or the “method detection limit”.
    Note, however that certain
    language at the end of federal paragraph
    (f)(2O)
    is capable
    of meaning that the “method detection limit”
    is used to
    derive the “detection limit”.
    The Board has chosen to
    disregard that language at the end of paragraph (f)(2O)
    in
    favor of the more direct language of paragraphs
    (f)(7)
    and
    (f) (11).
    “Method detection limit”,
    as used in subsections
    (q)
    and
    (t)
    below means the minimum concentration of
    a substance that
    can
    be
    measured
    and
    reported
    with
    99
    percent
    confidence
    that
    the analyte concentration is greater than zero and
    is
    determined from analysis of
    a sample in a given matrix
    containing the analyte.
    BOARD NOTE:
    Derived from 40 CFR 136, Appendix
    B (19934).
    The
    method
    detection
    limit
    is
    determined
    by
    the
    procedure
    set
    forth in 40 CFR
    136, Appendix
    B.
    See subsection
    (t)
    below.
    b)
    Required sampling.
    Each supplier shall take a
    minimum
    of
    one
    sample at each sampling point at the times required in subsection
    (u)
    below.
    C)
    Sampling points.
    1)
    Sampling points for
    GWSs.
    Unless otherwise provided by SEP,
    a GWS supplier shall take at least one sample from each of
    the following points:
    each entry point that
    is
    representative of each well after treatment.
    2)
    Sampling points for SWSs and mixed systems.
    Unless
    otherwise provided by SEP,
    a SWS or mixed system supplier
    shall
    sample from each of the following points:
    A)
    Each entry point after treatment;
    or
    B)
    Points
    in the distribution system that are
    representative of each source.
    3)
    The supplier shall take each sample
    at the same sampling
    point unless the Agency has granted a SEP that designates
    another location as more representative of each source,
    treatment plant,
    or within the distribution system.
    4)
    If
    a system draws water from more than one source,
    and the
    sources are combined before distribution, the supplier shall
    sample
    at an entry point during periods of normal operating
    conditions when water
    is representative of all sources being
    used.

    above derived from 40
    CFRI41.24(f)(l)
    through
    (f)(3)
    (19934).
    d)
    Each CWS and NTNCWS supplier shall take four consecutive quarterly
    samples for each of the Phase
    I VOCs,
    excluding vinyl chloride,
    and Phase
    II VOC5 during each compliance period, beginning
    in the
    compliance period starting
    in the
    initial compliance period.
    e)
    Reduction to annual monitoring frequency.
    If the initial
    monitoring for the Phase
    I,
    Phase
    II,
    and Phase V VOCs as allowed
    in subsection (r)(1)
    below has been completed by December
    31,
    1992,
    and the supplier did not detect any of the Phase
    I VOCa,
    including vinyl chloride,
    Phase
    II,
    or Phase V VOCs, then the
    supplier shall take one sample annually beginning in the initial
    compliance period.
    f)
    GWS reduction to triennial monitoring frequency.
    After
    a minimum
    of three years of annual
    sampling, GWS suppliers that have not
    previously detected any of the Phase
    I VOCs,
    including vinyl
    chloride,
    Phase
    II,
    or Phase V VOCs shall take one sample during
    each three—year compliance period.
    g)
    A
    CWS or NTNCWS supplier that has
    completed the initial round of
    monitoring required by subsection
    (d)
    above and which did not
    detect any of the Phase
    I VOCs,
    including vinyl chloride,
    Phase
    II,
    and Phase V VOCs may apply to the Agency for
    a SEP pursuant to
    Section 611.110 that releases
    it
    from the requirements of
    subsection
    (e)
    or
    (f)
    above.
    A supplier that serves
    fewer than
    3300 service connections may apply to the Agency for a
    SEP
    pursuant to
    Section 611.110
    that releases
    it from the requirements
    of subsection
    (d)
    above as to 1,2,4—trichlorobenzene.
    BOARD
    NOTE:
    Derived
    from 40 CFR 141.24(f)(7)
    and
    (f)(10)
    (19934),
    and the discussion at
    57 Fed. Reg.
    31825
    (July
    17,
    1992).
    Provisions concerning the term of the waiver appear below
    in
    subsections
    (i) and
    (j)
    below.
    The definition of
    “detect”,
    parenthetically added to the federal counterpart paragraph is
    in
    subsection
    (a)
    above.
    h)
    Vulnerability Assessment.
    The Agency shall consider the factors
    of Section 611.110(e)
    in granting a
    SEP from the requirements of
    subsections
    (d),
    (e),
    or
    (f)
    above sought pursuant to subsection
    (g) above.
    i)
    A SEP issued to a GWS pursuant to subsection
    (g) above is for a
    maximum of six years, except that a SEP as to the subsection
    (d)
    above monitoring for l,2,4—trichlorobenzene shall apply only to
    the initial round of monitoring.
    As
    a condition of
    a SEP, except
    as to a SEP from the initial round of subsection
    (d) above
    monitoring for 1,2,4-trichlorobenzene, the supplier shall, within
    30 months after the beginning of the period for which the waiver
    was issued,
    reconfirm its vulnerability assessment required by
    subsection
    (h) above and submitted pursuant to subsection
    (g)
    above, by taking
    one
    sample
    at
    each
    sampling
    point
    and
    reapplying
    for a SEP pursuant to subsection
    (g) above.
    Based on this
    application, the Agency shall either:
    1)
    If
    it determines that the PWS meets the standard of Section
    611.610(e),
    issue
    a SEP that reconfirms the prior SEP
    for
    the
    remaining
    three—year
    compliance
    period
    of
    the
    six—year
    maximum term;
    or,
    160
    2)
    Issue a new SEP requiring the supplier to sample annually.
    BOARD NOTE:
    This provision does not apply to SWS5 and mixed
    systems.
    j)
    Special considerations for SEPs for SWS and mixed systems.
    1)
    The Agency must determine that a SWS is not vulnerable
    before issuing a SEP pursuant to
    a SWS supplier.
    A SEP
    issued
    to
    a
    SWS
    or
    mixed
    system
    supplier
    pursuant
    to
    subsection
    (g)
    above
    is for a maximum of one compliance
    period; and
    2)
    The Agency may require,
    as
    a condition to a SEP issued to a
    SWS or mixed supplier,
    that the supplier take such samples
    for
    Phase
    I,
    Phase
    II,
    and Phase V VOC5 at
    such a frequency
    as the Agency determines are necessary,
    based on the
    vulnerability assessment.
    BOARD NOTE:
    There
    is a great
    degree
    of similarity between
    40 CFR 141.24(f)(7),
    the provision applicable to GWS5,
    and
    40 CFR l41.24(f)(lO), the provision for
    SWS5.
    The Board has
    consolidated the
    common
    requirements of both paragraphs into
    subsection
    (g)
    above.
    Subsection
    (j)
    above represents the
    elements unique to SWSs and mixed systems,
    and subsection
    (i)
    above relates to GWSs.
    Although
    40 CFR 141.24(f)(7)
    and
    (f)(1O)
    are silent as to mixed
    systems, the Board has
    included mixed systems with SWSs because this best follows
    the federal scheme for all other contaminants.
    k)
    If
    one of the Phase
    I VOCs, excluding vinyl chloride, Phase
    II,
    or
    Phase V VOCs
    is detected in any sample,
    then:
    1)
    The supplier shall monitor quarterly
    for that contaminant at
    each sampling point that resulted in a detection.
    2)
    Annual monitoring.
    A)
    The
    Agency shall grant
    a SEP pursuant to Section
    611.110 that allows a supplier to reduce the
    monitoring frequency to annual at
    a sampling point
    if
    it determines that the sampling point
    is reliably and
    consistently below the MCL.
    B)
    A request
    for a SEP must include the following minimal
    information:
    i)
    For
    a GWS,
    two quarterly samples.
    ii)
    For a SWS or mixed system,
    four quarterly
    samples.
    C)
    In issuing a SEP, the Agency shall
    specify the level
    of the contaminant upon which the “reliably and
    consistently” determination was based.
    All SEP5 that
    allow less frequent monitoring based on an Agency
    “reliably and consistently” determination shall
    include
    a
    condition
    requiring
    the
    supplier
    to
    resume
    quarterly monitoring pursuant to subsection
    (k)(l)
    above if
    it violates the MCL specified by Section
    611.311.
    161
    3)
    Suppliers that monitor annually shall monitor during the
    quarter(s) that previously yielded the highest analytical
    result.
    4)
    Suppliers that do not detect
    a contaminant at
    a sampling
    point
    in three consecutive annual samples may apply to the
    Agency for a SEP pursuant to Section 611.110 that allows it
    to discontinue monitoring for that contaminant at that
    point,
    as specified
    in subsection
    (g)
    above.
    5)
    A GWS
    supplier that has detected one or more of the two-
    carbon contaminants
    listed in subsection (k)(5)(A)
    below
    shall monitor quarterly for vinyl chloride as described in
    subsection
    (k)(5)(B)
    below,
    subject to the limitation of
    subsection
    (k)(5)(C)
    below.
    A)
    Two—carbon contaminants (Phase
    I
    or
    II VOC):
    1,2—Dichloroethane
    (Phase
    I)
    l,1—Dichloroethylene (Phase
    I)
    cis—1,2—Dichloroethylene (Phase
    II)
    trans—l, 2—Dichloroethylene
    (Phase II)
    Tetrachloroethylene
    (Phase
    II)
    l,l,1-Trichloroethylene
    (Phase
    I)
    Trichloroethylene
    (Phase
    I)
    B)
    The supplier shall sample quarterly
    for vinyl chloride
    at each sampling point
    at which
    it detected one or
    more
    of
    the
    two—carbon
    contaminants
    listed
    in
    subsection
    (k)(5)(A)
    above.
    C)
    The Agency shall grant a SEP pursuant to Section
    611.110 that allows the supplier to reduce the
    monitoring frequency for vinyl chloride
    at any
    sampling point to once
    in each three—year compliance
    period
    if
    it determines that the supplier has not
    detected vinyl
    chloride
    in first sample required by
    subsection
    (k)5)(B)
    above.
    1)
    Quarterly monitoring following MCL violations.
    1)
    Suppliers that violate an MCL for one of the Phase
    I VOC5,
    including vinyl chloride,
    Phase II,
    or Phase V VOCs,
    as
    determined by subsection
    (0)
    below,
    shall monitor quarterly
    for that contaminant,
    at the sampling point where the
    violation occurred,
    beginning the next quarter after the
    violation.
    2)
    Annual monitoring.
    A)
    The Agency shall grant a SEP pursuant to Section
    611.110 that allows a supplier to reduce the
    monitoring frequency to annually
    if
    it determines that
    the sampling point
    is reliably
    and consistently below
    the MCL.
    B)
    A request
    for
    a SEP must include the following minimal
    information:
    four quarterly samples.
    C)
    In issuing
    a SEP, the Agency
    shall specify the level
    of the contaminant upon which the
    “reliably and
    consistently” determination was based.
    All SEP5 that
    162
    allow less frequent monitoring based on an Agency
    “reliably and consistently” determination shall
    include
    a condition requiring the supplier to resume
    quarterly monitoring pursuant to subsection (l)(1)
    above
    if it violates the MCL specified by Section
    611.311.
    D)
    The supplier shall monitor during the quarter(s) that
    previously yielded the highest analytical result.
    m)
    Confirmation samples.
    The Agency may
    issue
    a SEP pursuant to
    Section 610.110 to require a supplier to use a confirmation sample
    for results that
    it
    finds dubious for whatever reason.
    The Agency
    must state its reasons
    for issuing the SEP
    if the SEP
    is Agency-
    initiated.
    1)
    If
    a supplier detects any of the Phase
    I, Phase
    II, or Phase
    V VOC5 in
    a sample, the supplier shall take
    a confirmation
    sample as
    soon as possible,
    but no later than
    14 days after
    the
    supplier receives notice of the detection.
    2)
    Averaging
    is
    as
    specified
    in subsection
    (0)
    below.
    3)
    The Agency shall delete the original or confirmation sample
    if
    it determines that
    a sampling error occurred,
    in which
    case the confirmation sample will replace the original or
    confirmation sample.
    n)
    This subsection corresponds with 40
    CFR 14l.24(f)(14),
    an optional
    U.S.~..EFAprovision relating to compositing of
    samples that ~
    EPA does not require for state programs.
    This statement maintains
    structural consistency with U~S~EPArules.
    0)
    Compliance with the MCL5 for the Phase
    I,
    Phase
    II,
    and Phase V
    VOC5 must be determined based on the analytical results obtained
    at each sampling point.
    1)
    For suppliers that conduct monitoring at
    a frequency greater
    than annual,
    compliance
    is determined by a running annual
    average of all samples taken at each sampling point.
    A)
    If the annual average of any sampling point
    is greater
    than
    the
    MCL,
    then
    the
    supplier
    is
    out
    of
    compliance.
    B)
    If the initial sample or a
    subsequent sample would
    cause the annual average to exceed the McL, then the
    supplier
    is out of compliance immediately.
    C)
    Any samples below the detection limit shall be deemed
    as zero for purposes of determining the annual
    average.
    2)
    If monitoring
    is conducted annually,
    or
    less frequently, the
    supplier is out of compliance
    if
    the level of
    a contaminant
    at any sampling point
    is greater than the MCL.
    If
    a
    confirmation sample
    is taken,
    the determination of
    compliance
    is based on the average of two samples.
    3)
    When the portion of the distribution system that
    is out of
    compliance
    is separable from other parts of the distribution
    system and has
    rio interconnections,
    the supplier may issue
    the public notice required by Subpart
    T of this Part only to
    163
    persons served by that portion of the distribution system
    that
    is
    not
    in
    compliance.

    first sampling result and used
    for compliance determination in
    accordance with subsection
    (i) below.
    The-
    Agency shall delete
    results of obvious sampling errors from this calculation.
    1)
    Analysis for vinyl chloride
    is required only
    for GW6o that have
    detected one or more of the following
    two
    carbon organic
    compounds, Trichloroethyleno, tetrachloroethylene,
    1,2—
    diohlorocthane,
    1,1,1—trichloroethanc,
    cis—1,2—dichloroethyleno,
    trana—1,2 dichloroethylcne or 1,1 dichlorocthylonc.
    The analysis
    for vinyl chloride is required at each distribution or entry point
    at which one or more of the two—carbon organic compounds were
    found.
    If the first
    analysis does
    not detect vinyl chloride,
    the
    Agency shall reduce the frequency of
    vinyl chloride monitoring to
    once every three years
    for that sample location or other sample
    1-ocationc that arc more representative of the same source.

    Section 611.648
    Phase
    II,
    Phase IIB,
    and
    Phase V Synthetic Organic
    Contaminants
    Analysis of the Phase
    II,
    Phase IIB,
    and Phase V SOC5 for the purposes of
    determining compliance with the MCL must be conducted as follows:
    a)
    Definitions.
    As used
    in this Section:
    “Detect or detection”
    means that the contaminant
    of interest
    is present
    at
    a level greater than or equal to the
    “detection limit.
    “Detection limit”
    means the
    level of the contaminant of
    interest that
    is
    specified in subsection
    r)
    below.
    BOARD NOTE:
    This
    is
    a “trigger level”
    for Phase
    II,
    Phase
    IIB,
    and Phase V SOC5
    inasmuch as it
    prompts further action.
    The use of the term “detect” or “detection”
    irt
    this section
    is not intended to include any analytical capability of
    quantifying lower levels of any contaminant,
    or the “method
    detection limit”.
    b)
    Required sampling.
    Each supplier shall take a minimum of one
    sample at each sampling point at the times required
    in subsection
    (q)
    below.
    BOARD NOTE:
    U~S~EPAstayed the effective date of the MCLs
    for
    aldicarb,
    aldicarb sulfone,
    and aldicarb sulf oxide at
    57 Fed.
    Reg.
    22178
    (May 27,
    1991).
    Section 611.311(c)
    includes this stay.
    However, despite the stay of the effectiveness of the MCLs for
    these three SOCs,
    suppliers must monitor for them.
    c)
    Sampling points.
    1)
    sampling points
    for G~SS.
    Unless otherwise provided by
    SE?,
    a GWS supplier shall take at
    least one sample from each of
    the following points:
    each entry point that
    is
    representative of each well
    after treatment.
    2)
    Sampling
    points
    for
    SWSs
    and
    mixed
    systems.
    Unless
    otherwise provided by SEP,
    a SWS or mixed system supplier
    shall
    sample from each of the following points:
    169
    A)
    Each entry point after treatment;
    or
    B)
    Points in the distribution system that are
    representative of each source.
    3)
    The
    supplier shall take each sample at the
    same
    sampling
    point unless the Agency has granted a SEP that designates
    another location
    as more representative of each source,
    treatment plant,
    or within the distribution system.
    4)
    If
    a system draws water from more than one source, and the
    sources are combined before distribution,
    the
    supplier shall
    sample
    at an entry point during periods of normal operating
    conditions when water
    is representative of all sources being
    used.
    BOARD NOTE:

    (h)(3)
    (l99~3-~).
    d)
    Monitoring
    frequency:
    1)
    Each CWS and NTNCWS supplier shall take four consecutive
    quarterly samples for each of the Phase
    II,
    Phase IIB,
    and
    Phase
    V SOCs during each compliance period, beginning in the
    three-year compliance period starting
    in the initial
    compliance period.
    2)
    Suppliers serving more than 3,300 persons that do not detect
    a contaminant
    in the initial compliance period,
    shall take a
    minimum of two quarterly samples
    in one year of each
    subsequent three—year compliance period.
    3)
    Suppliers serving less than or equal to 3,300 persons that
    do not detect
    a contaminant
    in the initial compliance
    period,
    shall take a minimum of
    one sample during each
    subsequent
    three—year compliance period.
    e)
    Reduction to annual monitoring
    frequency.
    A CWS or NTNCWS
    supplier may apply to the Agency for a SEP that releases
    it
    from
    the requirements of subsection
    (d)
    above.
    A SEP
    from the
    requirement of subsection
    (d)
    above shall last for only
    a single
    three—year compliance period.
    f)
    Vulnerability Assessment.
    The Agency shall grant
    a SEP from the
    requirements of subsection
    (d) above based on consideration of the
    factors set forth at Section 611.110(e).
    g)
    If one of the Phase
    II,
    Phase
    IIB,
    or Phase V SOC5
    is detected in
    any sample,
    then:
    1)
    The supplier shall monitor quarterly for the contaminant at
    each sampling point that resulted
    in
    a detection.
    2)
    Annual monitoring.
    A)
    A supplier may request that the Agency grant a SEP
    pursuant to Section 610.110 that reduces the
    monitoring frequency to annual.
    B)
    A request
    for
    a SEP must include the following minimal
    information:
    170
    i)
    For a GWS, two quarterly samples.
    ii)
    For a SWS or mixed system,
    four quarterly
    samples.
    C)
    The Agency shall grant
    a SEP that allows annual
    monitoring
    at
    a sampling point
    if
    it determines that
    the sampling point
    is reliably and consistently below
    the MCL.
    D)
    In issuing the SEP, the Agency shall specify the level
    of the contaminant upon which the “reliably and
    consistently” determination was based
    All SEP5 that
    allow less
    frequent monitoring based on an Agency
    “reliably
    and consistently” determination
    shall
    include a condition requiring the supplier to resume
    quarterly monitoring pursuant to subsection (g)(1)
    above
    if
    it detects any Phase
    II
    SOC.
    3)
    Suppliers that monitor annually shall monitor during the
    quarter(s)
    that previously yielded the highest analytical
    result.
    4)
    Suppliers that have three consecutive annual samples with no
    detection of
    a contaminant at a sampling point may apply to
    the Agency
    for
    a SEP with respect to that point,
    as
    specified in subsections
    (e)
    and
    (f)
    above.
    5)
    Monitoring for related contaminants.
    A)
    If monitoring results
    in detection of one or more of
    the related contaminants listed
    in subsection
    (g)(5)(B)
    below,
    subsequent monitoring shall analyze
    for all the related compounds
    in the respective group.
    B)
    Related contaminants:
    i)
    first group:
    aldicarb
    aldicarb
    sulfone
    aldicarb sulfoxide
    ii)
    second group:
    heptachlor
    heptachlor epoxide-r~.
    h)
    Quarterly monitoring following MCL violations.
    1)
    suppliers that violate an MCL for
    one of the Phase
    II,
    Phase
    IIB,
    or Phase V SOC5,
    as determined by subsection
    (k)
    below,
    shall monitor quarterly for that contaminant at the sampling
    point where the violation occurred, beginning the next
    quarter after the violation.
    2)
    Annual monitoring.
    A)
    A supplier may request that the Agency grant a SEP
    pursuant to Section 611.110 that reduces the
    monitoring frequency to annual.
    171
    B)
    A request for
    a SEP must
    include,
    at
    a minimum,
    the
    results from four quarterly samples.
    C)
    The Agency shall grant
    a SEP that allows annual
    monitoring at
    a sampling point
    if
    it determines that
    the sampling point
    is reliably and consistently below
    the MCL.
    D)
    In issuing the SE?,
    the Agency shall specify the level
    of the contaminant upon which the “reliably and
    consistently”
    determination was based
    All SEPa that
    allow
    less frequent monitoring based on an Agency
    ~‘reliablyand consistently” determination shall
    include a condition requiring the supplier to resume
    quarterly monitoring pursuant to subsection (h)(1)
    above
    if
    it detects any Phase
    II SOC.
    E)
    The supplier shall monitor during the quarter(s)
    that
    previously yielded the highest analytical
    result.
    i)
    Confirmation samples.
    1)
    If any of the Phase
    II,
    Phase
    IIB,
    or Phase V SOCs are
    detected in
    a sample,
    the supplier shall take a confirmation
    sample
    as soon
    as possible,
    but no later than 14 days after
    the supplier receives notice of the detection.
    2)
    Averaging
    is as specified
    in subsection
    (k) below.
    3)
    The Agency
    shall delete the original or confirmation
    sample
    if
    it determines that
    a sampling error occurred,
    in which
    case the confirmation sample will replace the original or
    confirmation sample.
    j)
    This subsection corresponds with 40 CFR l41.24(h)(1O),
    art
    optional
    U.!.S.~.EPA provision relating to compositing of samples that ~
    EPA does not require
    for state programs.
    This statement maintains
    structural consistency with Q~.S~EPArules.
    k)
    Compliance with the MCL5
    for the Phase
    II, Phase IIB, and Phase V
    SOCS
    shall be determined based on the analytical results obtained
    at each sampling point.
    1)
    For suppliers that are conducting monitoring at
    a frequency
    greater than annual,
    compliance
    is determined by a running
    annual average of all
    samples taken at each sampling point.
    A)
    If the annual average of any sampling point
    is greater
    than the MCL, then the supplier
    is out of
    compliance.
    B)
    If the initial sample or
    a subsequent sample would
    cause the annual average to be exceeded,
    then the
    supplier
    is out of compliance
    immediately.
    C)
    Any samples below the detection limit must be
    calculated as zero for purposes of determining the
    annual average.
    2)
    If monitoring is conducted annually or
    less frequently,
    the
    supplier
    is out of compliance
    if the level of
    a contaminant
    at any sampling point
    is greater than the MCL.
    If
    a
    172
    confirmation sample
    is taken, the determination of
    compliance
    is based on the average of two samples.
    3)
    When the portion
    of the distribution system that
    is out of
    compliance is separable from other parts of the distribution
    system and has no interconnections,
    the supplier may issue
    the public notice required by Subpart T of this Part only to
    persons served by that portion of the distribution system
    that
    is not
    in compliance.

    Analysis
    for PCBs must be conducted as
    follows using the methods
    in Section 611.645:
    1)
    Each supplier that monitors
    for PCBs
    shall analyze each
    sample using
    either U~S~EPAOrganic Methods, Method 505 or
    Method 508.
    2)
    If PCB5 are detected in any sample analyzed using U~S~..EPA
    Organic Methods, Methods
    505
    or 508,
    the supplier shall
    reanalyze the sample using Method 5O8A to quantitate the
    individual Aroclors
    (as decachlorobiphenyl).
    3)
    Compliance with the PCB MCL must be determined based upon
    the quantitative results of analyses using
    U~S~.EPA
    Organic
    Methods,
    Method 508A.
    it)
    Use of existing data.
    1)
    The Agency shall allow the use of data collected after
    January
    1,
    1990 but prior to the effective date of this
    174
    Section,
    pursuant to Agency sample request
    letters,
    if
    it
    determines that the data are generally consistent with the
    requirements of this Section.
    2)
    The Agency shall grant
    a SEP pursuant to Section 611.110
    that allows
    a supplier to monitor annually beginning
    in the
    initial compliance period
    if
    it determines that the supplier
    did not detect any Phase
    I VOC or Phase
    II VOC using
    existing data allowed pursuant to subsection
    (n)(1) above.
    0)
    The Agency shall issue a SEP that
    increases the number of sampling
    points or the frequency of monitoring
    if
    it determines that this
    is necessary to detect variations within the PWS due to such
    factors as fluctuations
    in contaminant concentration due to
    seasonal use or changes
    in the water source.

    Mandatory Health Effects Information
    1)
    Trichloroethylene.
    The United States Environmental Protection
    Agency
    (U.S. EPA)
    sets drinking water standards and has determined
    that
    trichloroethylene
    is
    a
    health
    concern
    at
    certain
    levels
    of
    exposure.
    This chemical
    is
    a common metal cleaning and dry
    cleaning fluid.
    It generally gets
    into drinking water by
    improper
    waste disposal.
    This chemical has been shown to cause cancer
    in
    laboratory animals such as rats and mice when the animals
    are
    exposed at high levels over their
    lifetimes.
    Chemicals that cause
    cancer in laboratory animals also may increase the risk of cancer
    in humans who are exposed at
    lower levels over long periods of
    time.
    U.S.
    EPA has set forth the enforceable drinking water
    standard for trichboroethylene at 0.005 parts per million
    (ppm) to
    reduce the risk of cancer or other adverse health effects which
    have been observed in laboratory animals.
    Drinking water which
    meets this standard
    is associated with little to none of this risk
    and should be considered safe.
    2)
    Carbon tetrachloride.
    The United States Environmental Protection
    Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined
    that
    carbon
    tetrachboride
    is
    a
    health
    concern
    at
    certain
    levels
    of
    exposure.
    This chemical was once
    a popular household cleaning
    fluid.
    It generally gets into drinking water by improper waste
    disposal.
    This chemical has been shown to cause cancer in
    laboratory animals such
    as rats and mice when the animals are
    exposed
    at high levels over their lifetimes.
    Chemicals that cause
    cancer in laboratory animals
    also may increase the risk of cancer
    in humans who are exposed at
    lower levels over long periods of
    time.
    U.S. EPA has set
    the enforceable drinking water standard
    for carbon tetrachloride
    at
    0.005 parts per million
    (ppm) to
    reduce the risk of cancer or other adverse health effects which
    have been observed in laboratory animals.
    Drinking water which
    meets this standard
    is associated with little to none of this risk
    and should be considered safe.
    3)
    1,2—Dichboroethane.
    The United States Environmental Protection
    Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined
    that 1,2—dichboroethane is
    a health concern at certain levels
    of
    exposure.
    This chemical
    is used as
    a cleaning fluid
    for
    fats,
    oils,
    waxes and resins.
    It generally gets into drinking water by
    improper waste disposal.
    This chemical has been shown to cause
    cancer
    in laboratory
    animals such as rats and mice when the
    animals are exposed at high levels over their
    lifetimes.
    Chemicals that cause cancer
    in laboratory animals also may
    increase the risk of cancer
    in humans who are exposed at lower
    levels over long periods of time.
    U.S. EPA has
    set the
    enforceable drinking water standard for l,2—dichloroethane
    at
    0.OOS parts per million
    (ppm)
    to reduce the risk of cancer or
    other adverse health effects which have been observed
    in
    179
    laboratory animals.
    Drinking water which meets this standard
    is
    associated with little to none of this risk and should be
    considered safe.
    4)
    Vinyl chloride.
    The United States Environmental Protection Agency
    (U.S. EPA)
    sets drinking water standards and has determined that
    vinyl chloride
    La a health concern at certain levels of exposure.
    This chemical
    is used in industry and
    is
    found in drinking water
    as a result of the breakdown of related solvents.
    The solvents
    are used
    as cleaners and degreasers of metals and generally get
    into drinking water by
    improper waste disposal.
    This chemical has
    been associated with significantly increased risks of cancer among
    certain industrial workers who were exposed to relatively large
    amounts of this chemical during their working careers.
    This
    chemical
    has
    also
    been
    shown
    to
    cause
    cancer
    in
    laboratory
    animals
    when the animals are exposed at high levels over their lifetimes.
    Chemicals that cause increased risk of cancer among exposed
    industrial workers and
    in
    laboratory animals also may increase the
    risk of cancer in humans who are exposed at
    lower levels over long
    periods
    of time.
    U.S. EPA has
    set the enforceable drinking water
    standard
    for
    vinyl
    chloride
    at
    0.002
    parts
    per
    million
    (ppm)
    to
    reduce the risk of cancer or other adverse health effects which
    have been observed in
    laboratory animals.
    Drinking water which
    meets this standard is
    associated with little to none of this risk
    and should be considered
    safe.
    5)
    Benzene.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water
    standards and has determined that benzene
    is
    a health concern at certain levels of exposure.
    This chemical
    is used
    as
    a solvent and degreaser of metals.
    It
    is
    also a major
    component of gasoline.
    Drinking water contamination generally
    results from leaking underground gasoline and petroleum tanks or
    improper waste disposal.
    This chemical has been associated with
    significantly increased risks
    of
    leukemia among certain industrial
    workers who were exposed to relatively
    large amounts of this
    chemical during their working careers.
    This chemical has been
    shown to cause cancer
    in
    laboratory animals when the animals are
    exposed at high levels over their
    lifetimes.
    Chemicals that cause
    increased risk of cancer among exposed industrial workers and
    in
    laboratory animals also may increase the risk of cancer
    in humans
    who are exposed at lower levels over long periods of time.
    U.S.
    EPA has
    set the enforceable drinking water standard for benzene at
    0.005 parts per million
    (ppm)
    to reduce the risk of cancer or
    other adverse health effects which
    have been observed in humans
    and laboratory animals.
    Drinking water which meets this standard
    is associated with little to
    none of this risk and should be
    considered safe.
    6)
    1,1-Dichioroethylene.
    The United States Environmental Protection
    Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined
    that 1,1—dichloroethylene
    is
    a health concern at certain
    levels of
    exposure.
    This chemical
    is used in industry and is found in
    drinking
    water as a result of the breakdown of related solvents.
    The solvents are used as cleaners and degreasers of metals and
    generally get into drinking water by improper waste disposal.
    This chemical has been shown to cause
    liver and kidney damage in
    laboratory animals such as rats and mice when the animals are
    exposed at high
    levels over their lifetimes.
    Chemicals that cause
    adverse effects
    in laboratory animals also may cause adverse
    health effects
    in humans who are exposed at lower
    levels over long
    periods of time.
    U.S. EPA has
    set the enforceable drinking water
    standard for 1,1-dichloroethylene
    at 0.007
    parts per million
    (ppm)
    180
    to reduce the risk of these adverse health effects which have been
    observed
    in
    laboratory animals.
    Drinking water which meets this
    standard
    is associated with little to none of this risk and should
    be considered safe.
    7)
    Para—dichlorobenzene.
    The United States Environmental Protection
    Agency
    (U.S.
    EPA)
    sets drinking water
    standards and has determined
    that para—dichlorobenzene is
    a health concern at certain levels of
    exposure.
    This chemical
    is
    a component of deodorizers, moth balls
    and pesticides.
    It generally gets into drinking water by improper
    waste disposal.
    This chemical has been shown to cause liver and
    kidney
    damage
    in laboratory animals such
    as rats and mice when the
    animals
    are
    exposed
    at
    high
    levels
    over
    their
    lifetimes.
    Chemicals which cause adverse effects
    in laboratory animals also
    may cause adverse health effects in humans who are exposed at
    lower levels over long periods of time.
    U.S. EPA has set the
    enforceable drinking water standard for para—dichlorobenzene at
    0.075 parts per million
    (ppm) to reduce the risk of these adverse
    health effects which have been observed in
    laboratory animals.
    Drinking
    water
    which
    meets
    this
    standard
    is
    associated
    with
    little
    to
    none of this risk and should be considered safe.
    8)
    1,1,1—Trichloroethane.
    The United States Environmental Protection
    Agency
    (U.S. EPA)
    sets drinking water standards and has determined
    that l,1,1—trichloroethane
    is
    a health concern
    at certain
    levels
    of exposure.
    This chemical
    is used as
    a cleaner and degreaser of
    metals.
    It generally gets
    into drinking water by improper waste
    disposal.
    This chemical has been shown to damage the liver,
    nervous system and circulatory system of
    laboratory animals such
    as rats and mice when the animals are exposed at high levels over
    their lifetimes.
    Some industrial workers who were exposed to
    relatively large amounts of this chemical during their working
    careers also suffered damage to the liver,
    nervous system and
    circulatory system.
    Chemicals which cause adverse effects among
    exposed industrial workers
    and
    in laboratory animals also may
    cause adverse health effects
    in humans who are exposed at lower
    levels over long periods of time.
    U.S.
    EPA has set the
    enforceable drinking water standard for l,1,1—trichloroethane at
    0.2
    parts per million
    (ppm) to protect against the risk of these
    adverse health effects which have been observed in laboratory
    animals.
    Drinking water which meets this standard is associated
    with little to none of this risk and should be considered safe.
    9)
    Fluoride.
    The U.S. Environmental Protection Agency requires that
    we
    send
    you
    this
    notice
    on
    the
    level
    of
    fluoride
    in
    your
    drinking
    water.
    The drinking water
    in your community has
    a fluoride
    concentration of
    Iconcentration
    to
    be provided by supplierl
    milligrams per liter
    (mg/L).
    Federal regulations require that
    fluoride, which occurs naturally
    in your water supply,
    not exceed a concentration of 4.0 mg/L
    in
    drinking water.
    This
    is
    an enforceable standard called a Maximum
    Contaminant Level
    (MCL),
    and
    it has been established to
    protect
    the public health.
    Exposure to drinking water levels above 4.0
    mg/L for many years may result
    in some cases of crippling skeletal
    fluorosis, which
    is
    a serious bone disorder.
    Federal law also requires that we notify you when monitoring
    indicates that the fluoride in your drinking water exceeds 2.0
    mg/L.
    This
    is intended to alert families about dental problems
    that might affect children under nine years of age.
    The fluoride
    concentration of your water exceeds this federal guideline.
    181
    Fluoride in children’s drinking water at levels of approximately
    1
    mg/L reduces the number of dental
    cavities.
    However,
    some
    children exposed to levels of
    fluoride greater than about 2.0 mg/L
    may develop dental fluorosis.
    Dental fluorosis,
    in its moderate
    and severe forms,
    is
    a brown staining and/or pitting of the
    permanent teeth.
    Because dental flusrosis occurs only when developing teeth
    (before
    they erupt from the gums)
    are exposed to elevated fluoride levels,
    households without children are not expected to be affected by
    this level of fluoride.
    Families with children under the age of
    nine are encouraged to seek other
    sources of
    drinking water for
    their children to avoid the possibility of staining and pitting.
    Your water supplier can lower the concentration of
    fluoride
    in
    your water so that you will still
    receive the benefits of cavity
    prevention while the possibility of stained and pitted teeth is
    minimized.
    Removal of
    fluoride may
    increase your water costs.
    Treatment systems are also commercially available for home use.
    Information
    on such systems
    is available at the address given
    below.
    Low fluoride bottled drinking water that would meet all
    standards
    is also commercially available.
    For further information, contact mama of contact person to be
    provided by supplierl
    at your water system.
    BOARD NOTE:
    Derived from 40 CFR 141.32(e) (9)
    and 143.5
    (1992-4).
    10)
    Microbiological contaminants
    (for use when there is a violation of
    the treatment technique requirements for filtration and
    disinfection
    in Subpart
    B of this Part).
    The United States
    Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water
    standards and has determined that the presence of microbiological
    contaminants are a health concern
    at certain levels of exposure.
    If water
    is
    inadequately treated, microbiological contaminants in
    that water may cause
    disease.
    Disease symptoms may include
    diarrhea,
    cramps,
    nausea and possibly
    jaundice and any associated
    headaches and fatigue.
    These
    symptoms,
    however,
    are not just
    associated with disease—causing organisms
    in drinking water, but
    also may be caused by a number of
    factors other than your drinking
    water.
    U.S. EPA has set enforceable requirements for treating
    drinking water to reduce the risk of these adverse health effects.
    Treatment such
    as filtering and disinfecting the water removes or
    destroys microbiological contaminants.
    Drinking water which
    is
    treated
    to
    meet
    U.S.
    EPA
    requirements
    is
    associated
    with
    little
    to
    none of this risk and should be considered safe.
    11)
    Total coliforms.
    (To be used when there
    is
    a violation of Section
    611.325(a)
    and not
    a violation of
    Section 611.325(b)).
    The United
    States Environmental Protection Agency
    (U.S. EPA)
    sets drinking
    water standards
    and has determined that the presence of total
    coliforms
    is
    a possible health concern.
    Total coliforms are
    common in the environment and are generally not harmful
    themselves.
    The presence of these bacteria
    in drinking water,
    however, generally is a result of
    a problem with water treatment
    or the pipes which distribute
    the water and indicates that the
    water may be contaminated with organisms that can cause disease.
    Disease symptoms may
    include diarrhea,
    cramps, nausea and possibly
    jaundice,
    and any associated headaches and fatigue.
    These
    symptoms,
    however, are not
    just associated with disease—causing
    organisms in drinking water, but also may be caused by a number of
    factors other than your drinking water.
    U.S.
    EPA has set an
    182
    enforceable drinking water standard
    for total coliforms to reduce
    the risk of these adverse health effects.
    Under this standard,
    no
    more
    than 5.0 percent of the samples collected during a month can
    contain these bacteria,
    except that systems collecting fewer than
    40 samples/month that have one total coliform-positive sample per
    month are not violating the standard.
    Drinking water which meets
    this standard is usually not associated with a health risk from
    disease—causing bacteria and should be considered safe.
    12)
    Fecal Coliforms/E.
    coli.
    (To be used when there
    is
    a violation of
    Section 611.325(b) or both Section 611.325(a) and (b)+.j
    The
    United States Environmental Protection Agency
    (U.S.
    EPA)
    sets
    drinking water standards and has determined that
    the presence of
    fecal coliforms or E.
    coli
    is
    a serious health concern.
    Fecal
    coliforms and E. coli are generally not harmful
    themselves, but
    their presence
    in drinking water
    is serious because they usually
    are associated with sewage or animal wastes.
    The presence of
    these bacteria
    in drinking water
    is generally
    a result of
    a
    problem with water treatment or the pipes which distribute the
    water and indicates that the water may be contaminated with
    organisms
    that
    can
    cause
    disease.
    Disease
    symptoms
    may
    include
    diarrhea,
    cramps,
    nausea and possibly jaundice,
    and associated
    headaches and fatigue.
    These symptoms, however,
    are not just
    associated with disease—causing organisms
    in drinking water,
    but
    also may be caused by a number of
    factors other than your drinking
    water.
    U.S. EPA has
    set
    an enforceable drinking water standard
    for fecal coliforms and E.
    coli to reduce the risk of these
    adverse health effects.
    Under this standard all drinking water
    samples
    must be free of these bacteria.
    Drinking water which
    meets this standard
    is associated with little or none of this risk
    and should be considered safe.
    State and local
    health authorities
    recommend that consumers take the following precautions:
    (To be
    inserted by the public water system,
    according to instruction from
    State or local
    authorities).
    13)
    Lead.
    The United States Environmental Protection Agency
    (U.S.
    EPA) sets drinking water standards and has determined that lead
    is
    a health
    concern
    at
    certain
    exposure
    levels.
    Materials
    that
    contain lead have frequently been used
    in the construction of
    water supply distribution systems,
    and plumbing systems
    in private
    homes and other buildings.
    The most commonly found materials
    include service lines,
    pipes,
    brass and bronze fixtures,
    and
    solders and fluxes.
    Lead
    in these materials can contaminate
    drinking water as a result of the corrosion that takes place when
    water comes into contact with those materials.
    Lead can cause
    a
    variety of adverse health effects
    in humans.
    At relatively low
    levels of exposure,
    these effects may include interference with
    red blood cell chemistry,
    delays
    in normal physical and mental
    development in babies and young children,
    slight deficits in the
    attention span,
    hearing, and learning abilities of children,
    and
    slight increases in the blood pressure of some adults.
    U.S.
    EPA’s
    national primary drinking water regulation requires all public
    water systems to optimize corrosion control to minimize lead
    contamination resulting from the corrosion of plumbing materials.
    Public water systems serving 50,000 people or fewer that have lead
    concentrations below 15 parts per billion
    (ppb)
    in more than 90
    of tap water samples
    (the U.S. EPA “action level”)
    have optimized
    their corrosion control treatment.
    Any water system that exceeds
    the action level must also monitor their source water to determine
    whether treatment to remove lead in source water is
    needed.
    Any
    water system that continues to exceed the action level after
    installation
    of
    corrosion
    control
    and/or
    source
    water
    treatment
    183
    must
    eventually
    replace
    all
    lead
    service
    lines
    contributing
    in
    excess of 15 ppb of lead to drinking water.
    Any water system that
    exceeds the action level must also undertake a public education
    program to inform consumers of ways they can reduce their exposure
    to potentially high levels of lead
    in
    drinking water.
    14)
    Copper.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined that copper
    is
    a health concern at certain exposure levels.
    Copper,
    a
    reddish-brown metal,
    is often used to plumb residential and
    commercial structures that are connected to water distribution
    systems.
    Copper contaminating drinking water
    as a corrosion by-
    product occurs
    as the result of the corrosion of copper pipes that
    remain
    in contact with water
    for
    a prolonged period of time.
    Copper
    is an essential nutrient,
    but
    at high doses
    it has been
    shown to cause stomach and intestinal distress,
    liver and kidney
    damage,
    and anemia.
    Persons with Wilson’s disease may be at a
    higher risk of health effects due to copper than the general
    public.
    U.S. EPA’s national primary drinking water regulation
    requires all public water systems to install optimal
    corrosion
    control to minimize copper contamination resulting from the
    corrosion of plumbing materials.
    Public water systems serving
    50,000 people or fewer that have copper concentrations below 1.3
    parts per million (ppm)
    in more than 90
    of tap water samples
    (the
    U.S.
    EPA “action level”)
    are not required to install or improve
    their treatment.
    Any water system that exceeds the action level
    must also monitor their source water to determine whether
    treatment to remove copper
    in source water
    is needed.
    15)
    Asbestos.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined that
    asbestos
    fibers greater than 10 micrometers in length are a health
    concern at certain levels of exposure.
    Asbestos
    is
    a naturally
    occurring mineral.
    Most asbestos fibers
    in drinking
    water
    are
    less
    than
    10
    micrometers
    in
    length
    and
    occur
    in
    drinking
    water
    from natural sources and from corroded asbestos—cement pipes in
    the distribution system.
    The major uses of asbestos were in the
    production of cements,
    floor tiles,
    paper products,
    paint,
    and
    caulking;
    in transportation-related applications;
    and in the
    production of textiles and plastics.
    Asbestos was once
    a popular
    insulating and fire retardant material.
    Inhalation studies have
    shown that various forms of asbestos have produced lung tumors
    in
    laboratory animals.
    The available information on the risk of
    developing gastrointestinal tract cancer associated with the
    ingestion of asbestos from drinking water
    is limited.
    Ingestion
    of intermediate—range chrysolite asbestos
    fibers greater than 10
    micrometers
    in
    length
    is
    associated
    with
    causing
    benign
    tumors
    in
    male rats.
    Chemicals that cause cancer in laboratory animals also
    may increase the risk of
    cancer
    in humans who are exposed over
    long periods of time.
    U.S. EPA has
    set
    the drinking water
    standard
    for
    asbestos
    at
    7
    million
    long
    fibers
    per
    liter
    to
    reduce
    the potential risk of cancer or other adverse health effects which
    have been observed
    in laboratory animals.
    Drinking water which
    meets the U.S. EPA standard
    is associated with little to none of
    this risk and should be considered safe with respect to asbestos.
    16)
    Barium.
    The United States Environmental Protection Agency
    (U.S.
    EPA) sets drinking water standards and has determined that barium
    is
    a health concern at certain levels of exposure.
    This inorganic
    chemical occurs naturally in some aquifers that serve as sources
    of groundwater.
    It
    is also used in oil and gas drilling muds,
    automotive paints,
    bricks, tiles,
    and jet fuels.
    It generally
    184
    gets into drinking water after dissolving from naturally occurring
    minerals in the ground.
    This chemical may damage the heart and
    vascular system,
    and
    is associated with
    high blood pressure
    in
    laboratory animals such as rats exposed to high levels during
    their lifetimes.
    In humans, U.S.
    EPA believes that effects from
    barium on blood pressure should
    riot occur below
    2 parts per
    million
    (ppm)
    in drinking water.
    U.S. EPA has set the drinking
    water standard for barium
    at
    2 parts per million
    (ppm)
    to protect
    against the risk of these
    adverse health effects.
    Drinking water
    that
    meets
    the
    U.S.
    EPA
    standard
    is
    associated
    with
    little
    to
    none
    of this risk and
    is considered safe with respect to barium.
    17)
    Cadmium.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water
    standards and has determined that cadmium
    is
    a health concern at certain levels of exposure.
    Food and the
    smoking of tobacco are common sources of general exposure.
    This
    inorganic metal
    is a contaminant
    in the metals used to galvanize
    pipe.
    It
    generally
    gets
    into
    water
    by
    corrosion
    of
    galvanized
    pipes or by improper waste disposal.
    This chemical has been shown
    to damage the kidney in animals such as rats and mice when the
    animals are exposed at high levels over their lifetimes.
    Some
    industrial workers who were exposed to relatively large amounts of
    this chemical during working careers also suffered damage to the
    kidney.
    U.S. EPA has
    set the drinking water standard for cadmium
    at 0.005 parts per million
    (ppm)
    to protect against the risk of
    these adverse health effects.
    Drinking water that meets the U.S.
    EPA standard
    is associated with little to none of this risk and is
    considered safe with respect to cadmium.
    18)
    Chromium.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined that
    chromium
    is
    a health concern at certain levels of exposure.
    This
    inorganic metal occurs naturally
    in the ground and
    is often used
    in the
    electroplating of metals.
    It generally gets into water
    from
    runoff
    from
    old
    mining
    operations
    and
    improper
    waste
    disposal
    from plating operations.
    This chemical has been shown to damage
    the kidney,
    nervous system,
    and the circulatory system of
    laboratory animals such as rats and mice when the animals are
    exposed at high
    levels. Some humans who were exposed to high
    levels of this chemical suffered liver and kidney damage,
    dermatitis and respiratory problems.
    U.S. EPA has
    set the
    drinking water standard
    for chromium at 0.1 parts per million
    (ppm)
    to protect against the risk of these adverse health effects.
    Drinking water that meets the U.S. EPA standard
    is associated with
    little to none of this risk and is
    considered safe with respect to
    chromium.
    19)
    Mercury.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined that mercury
    is
    a health concern at certain levels of exposure.
    This inorganic
    metal
    is used
    in electrical equipment and some water pumps.
    It
    usually gets into water as a result of
    improper waste disposal.
    This
    chemical
    has
    been
    shown
    to
    damage
    the
    kidney
    of
    laboratory
    animals such as rats when the animals are exposed at high levels
    over their lifetimes.
    U.S. EPA has set the drinking water
    standard for mercury at 0.002 parts per million
    (ppm) to protect
    against the risk of these adverse health effects.
    Drinking water
    that meets the U.S. EPA standard is associated with little to none
    of this risk and is
    considered safe with respect to mercury.
    20)
    Nitrate.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined that nitrate
    185
    poses an acute health concern at certain levels of exposure.
    Nitrate is used
    in fertilizer and
    is
    found in sewage and wastes
    from
    human
    and/or
    farm
    animals
    and
    generally
    gets
    into
    drinking
    water from those activities.
    Excessive levels
    of nitrate
    in
    drinking water have caused serious illness and sometimes death in
    infants under six months of
    age.
    The serious illness in infants
    is caused because nitrate
    is converted to nitrite in the body.
    Nitrite interferes with the oxygen carrying capacity of the
    child’s blood.
    This is an acute disease
    in that symptoms can
    develop rapidly in
    infants.
    In most cases, health deteriorates
    over a period of days.
    Symptoms include shortness of breath and
    blueness of the skin.
    Clearly, expert medical advice should be
    sought
    immediately
    if these symptoms occur.
    The purpose of this
    notice
    is to encourage parents and other responsible
    parties to
    provide infants with an alternate source of drinking water.
    Local
    and State health authorities are the
    best
    source for information
    concerning alternate sources of drinking water
    for
    infants.
    U.S.
    EPA has
    set the drinking water
    standard at
    10 parts per million
    (ppm)
    for nitrate to protect
    against the risk of these adverse
    effects.
    U.S. EPA has also set
    a drinking water standard for
    nitrite at
    1 ppm.
    To allow for the
    fact that the toxicity of
    nitrate and nitrite are additive.
    U.S. EPA has also established a
    standard
    for
    the
    sum
    of
    nitrate
    and
    nitrite
    at
    10
    ppm.
    Drinking
    water
    that
    meets
    the
    U.S.
    EPA
    standard
    is
    associated
    with
    little
    to none of this risk and
    is considered safe with respect to
    nitrate.
    21)
    Nitrite.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined that nitrite
    poses an acute health concern
    at certain levels of exposure.
    This
    inorganic chemical
    is used
    in fertilizers and
    is found in sewage
    and wastes from humans and/or farm animals and generally gets into
    drinking water as
    a result of those activities.
    While excessive
    levels of nitrite in drinking water have not been observed,
    other
    sources of nitrite have caused
    serious illness and sometimes death
    in
    infants under six months of
    age.
    The serious
    illness in
    infants
    is caused because nitrite interferes with the oxygen
    carrying capacity of the child’s blood.
    This
    is an acute disease
    in that symptoms can develop rapidly.
    However,
    in most cases,
    health deteriorates over a period of days.
    Symptoms
    include
    shortness of breath and blueness of the skin.
    Clearly, expert
    medical advice should be sought immediately
    if these symptoms
    occur.
    The purpose of this notice
    is to encourage parents and
    other responsible parties to provide infants with an alternate
    source of
    drinking water.
    Local and State health authorities are
    the best source
    for information concerning alternate sources of
    drinking water for
    infants.
    U.S. EPA
    has
    set the drinking water
    standard
    at
    1 part per million
    (ppm)
    for nitrite to protect
    against the risk of these adverse effects.
    U.S. EPA has also set
    a drinking water standard for nitrate
    (converted to nitrite in
    humans)
    at
    10 ppm and for the sum of nitrate and nitrite at
    10
    ppm.
    Drinking water that meets the U.S. EPA standard
    is
    associated with little to none of this risk and
    is considered safe
    with
    respect
    to
    nitrite.
    22)
    Selenium.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined that
    selenium is
    a health concern at
    certain high levels of exposure.
    Selenium is also an essential nutrient at low levels of exposure.
    This
    inorganic chemical
    is found naturally in food and soils and
    is used
    in electronics,
    photocopy operations,
    the manufacture
    of
    glass,
    chemicals,
    drugs,
    and
    as
    a fungicide and
    a feed additive.
    186
    In humans,
    exposure to high levels of selenium over a long period
    of time has resulted in a number of
    adverse health effects,
    including a loss of feeling and control in the arms and legs.
    U.S. EPA has set the drinking water standard for selenium at 0.05
    parts per million
    (ppm)
    to protect against the risk of
    these
    adverse health effects.
    Drinking water that meets the U.S. EPA
    standard
    is associated with little to none of this risk and
    is
    considered safe with respect to selenium.
    23)
    Acrylamide.
    The United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined that
    acrylamide
    is a health concern at certain levels of exposure.
    Polymers made from acrylamide are sometimes used to treat water
    supplies to remove particulate contaminants.
    Acrylarnide has been
    shown to cause cancer
    in laboratory animals such as rats and mice
    when the animals are exposed at high levels over their lifetimes.
    Chemicals that cause cancer
    in laboratory animals also may
    increase the risk of cancer
    in humans who are exposed over long
    periods of time.
    Sufficiently large doses of acrylamide are known
    to cause neurological injury.
    U.S. EPA has set the drinking water
    standard for acrylamide using
    a treatment technique to reduce the
    risk of cancer or other adverse health effects which have been
    observed in laboratory animals.
    This treatment technique limits
    the amount of acrylamide
    in the polymer and the amount of the
    polymer which may be added to drinking water to remove
    particulates.
    Drinking water systems which comply with thia
    treatment technique have little to no risk and are considered safe
    with respect to acrylamide.
    24)
    Alachlor.
    The
    United States Environmental Protection Agency
    (U.S.
    EPA)
    sets drinking water standards and has determined that
    alachlor
    is
    a health concern at certain
    levels of exposure.
    This
    organic chemical is
    a widely used pesticide.
    When soil and
    climatic conditions are favorable,
    alachlor may get into drinking
    water by runoff into surface water or by leaching into
    groundwater.
    This chemical has been shown to cause cancer in
    laboratory animals such
    as rats
    and mice when the animals are
    exposed at high levels over their lifetimes. Chemicals that cause
    cancer in laboratory animals also may increase the risk of
    cancer
    in humans who are exposed over
    long periods of time.
    U.S. EPA has
    set the drinking water standard for alachlor at 0.002 parts per
    million
    (ppm)
    to reduce
    the risk of cancer or other adverse health
    effects which have been observed
    in
    laboratory animals.
    Drinking
    water that meets this
    standard
    is associated with little to none
    of this risk and
    is considered safe with respect to alachlor.

    Aldicarb
    is
    a widely used pesticide.
    Under certain soil and
    climatic conditions
    (e.g.,
    sandy soil and high rainfall),
    aldicarb
    may leach into groundwater after normal agricultural applications
    to crops such as potatoes or peanuts or may enter drinking water
    supplies as a result of surface runoff.
    This chemical has been
    shown to damage the nervous system in laboratory animals such as
    rats
    and
    dogs
    exposed
    to
    high
    levels.
    U.S.
    EPA
    has
    set
    the
    drinking water standard for aldicarb
    at 0.003 parts per million
    (ppm)
    to reduce the risk of adverse health effects.
    Drinking
    water that meets this standard
    is associated with little to none
    of this risk and
    is considered safe with respect to aldicarb.
    187
    26)
    Aldicarb sulfoxide.

    concern
    at
    certain
    levels
    of
    exposure.
    Aldicarb
    is
    a widely used pesticide.
    Aldicarb
    sulfoxide in groundwater
    is primarily
    a breakdown product of
    aldicarb.
    Under certain soil and climatic conditions
    (e.g.,
    sandy
    soil
    and
    high
    rainfall),
    aldicarb
    sulfoxide
    may
    leach
    into
    groundwater after normal agricultural applications to crops such
    as potatoes or peanuts or may enter drinking water supplies as
    a
    result of surface runoff.
    This chemical has been shown to damage
    the nervous system in laboratory animals
    such as rats and dogs
    exposed to high levels.
    U.S. EPA has
    set the drinking water
    standard for aldicarb sulfoxide
    at 0.004 parts per million
    (ppm)

    by improper use of these polymers.
    This chemical
    has been shown
    to cause cancer in laboratory animals such as rats and mice when
    the animals are exposed at high levels over their lifetimes.
    Chemicals that cause cancer in laboratory animals also may
    increase the risk of cancer
    in humans who are exposed over long
    periods of time.
    U.S.
    EPA
    has set the drinking water standard for
    epichlorohydrin using a treatment technique to reduce the risk of
    cancer or other adverse health effects which have been observed in
    laboratory animals.
    This treatment technique
    limits the amount of
    epichlorohydrin
    in the polymer and the amount of the polymer which
    may be added to drinking water as
    a flocculent to remove
    particulates.
    Drinking water systems which comply with this
    treatment technique have little to no risk and are considered safe

    gets
    into
    drinking
    water
    by
    discharges
    from
    industrial
    activities.
    This
    chemical
    has
    been
    shown
    to
    cause
    damage
    to
    several organs,
    including the adrenal
    glands.
    U.S. EPA has
    set
    the drinking water standard for l,2,4—trichlorobenzene at 0.07
    parts per million
    (ppm)
    to protect against the risk of these
    adverse health effects.
    Drinking water that meets the U.S. EPA
    standard
    is associated with little to none of this risk and
    is
    considered safe with respect to l,,2,4—trichlorobenzene.

    74)
    1,1,2—Trichloroethane.
    The
    United States Environmental Protection
    Agency
    (U.S. EPA)
    sets drinking water standards and has determined
    that 1,1,2—trichloroethane is
    a health concern at certain levels
    of exposure.
    This organic chemical
    is an intermediate in the
    production
    of 1,1—dichloroethylene.
    It generally gets into water
    by
    industrial discharge of wastes.
    This chemical has been shown
    to damage the kidney and liver of laboratory animals such as rats
    exposed to high levels during their lifetimes.
    U.S. EPA has set
    the drinking water standard for l,l,2—trichloroethane at 0.005
    parts
    per
    million
    (ppm)
    to
    protect
    against
    the
    risk
    of
    these
    adverse
    health
    effects.
    Drinking
    water
    that
    meets
    the
    U.S.
    EPA
    standard
    is associated with little to none of this risk and
    is
    considered safe with respect to 1,1,2—trichloroethane.

    2,3,7,8—TCDD
    (dioxin).
    The United States Environmental Protection
    Agency
    (U.S. EPA)
    sets drinking water standards and has determined
    that dioxin is
    a health concern at certain Levels of exposure.
    This organic chemical
    is an impurity in the production of some
    pesticides.
    It may get into
    drinking
    water
    by
    industrial
    discharge of wastes.
    This chemical
    has been shown to cause cancer
    in laboratory animals such
    as rats and mice when the animals are
    exposed to high levels during their lifetimes.
    Chemicals that
    cause cancer in laboratory animals also may increase the risk of
    cancer
    in humans who are exposed over
    long periods of time.
    U.S.
    EPA has
    set the drinking water standard for dioxin at 0.00000003
    parts per million
    (ppm)
    to protect against the risk of cancer or
    other
    adverse health effects.
    Drinking water that meets the U.S.
    EPA standard
    is associated with little to none of this risk and is
    considered safe with respect to dioxin.
