    OPINION AND ORDER OF THE BOARD (by R.C. Flemal):
    BACKGROUND
    Under Section 17.5 of the Environmental Protection Act (Act) (415 ILCS 5/17.5 (1998)),
    the Board today adopts amendments to the Illinois regulations that are “identical in substance”
    (IIS) to the National Primary Drinking Water regulations (NPDWRs) adopted by the United States
    Environmental Protection Agency (USEPA). These regulations implement sections 1412(b),
    1414(c), 1417(a), and 1445(a) of the Safe Drinking Water Act (SDWA), 42 U.S.C. §§ 300g-1(b),
    300g-3(c), 300g-6(a), and 300j-4(a)(1996). The nominal timeframe of this docket includes
    SDWA amendments that the USEPA adopted in the period from July 1, 1999, through December
    31, 1999. The federal SDWA regulations are found at 40 C.F.R. §§ 141 and 142. The USEPA
    took two actions during the nominal timeframe period that could necessitate Board action, but, as
    explained below, in response to public comment the Board is incorporating only one federal action
    into the Board’s rules. The final rule adopted today includes the addition of analytical methods
    approved for determining compliance with the drinking water regulations.
    Section 17.5 of the Act (415 ILCS 5/17.5 (1998)) provides for quick adoption of
    regulations that are “identical in substance” to federal regulations that the USEPA adopts to
    implement sections 1412(b), 1414(c), 1417(a), and 1445(a) of the SDWA. Section 17.5 of the Act
    also provides that Title VII of the Act (415 ILCS 5/1
    et seq
    . (1998)) and Section 5 of the
    Administrative Procedure Act (APA) (5 ILCS 100/5-35 & 5-40 (1998)) do not apply to the
    Board’s adoption of IIS regulations. Accordingly, this rulemaking is not subject to first or second-
    notice review by the Joint Committee on Administrative Rules (JCAR). However, to facilitate
    receipt of public comments, the Board’s June 8, 2000 proposal for public comment was published
    in the
    Illinois Register
    . 24 Ill. Reg. 8728 (June 30, 2000).
    Section 7.2(b) of the Act (415 ILCS 5/7.2 (1998)) requires the Board to complete its IIS rulemaking actions
    within one year of the date of the earliest federal amendments involved in a docket. In this docket, the earliest
    federal action requiring Board action occurred on September 17, 1999. Thus, the Board must complete its
    rulemaking activity in this docket prior to September 17, 2000.
    FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING
    2
    This rulemaking incorporates certain federal amendments that occurred during the period of July 1, 1999,
    through December 31, 1999. The SDWA regulations are found at 40 C.F.R. §§ 141-142. The USEPA amended the
    federal SDWA regulations two times during that period: September 17, 1999, and December 1, 1999. This
    rulemaking considers both of these actions. As explained below, only the December 1, 1999 action requires
    corresponding Board action.
    The federal amendments incorporated into this rulemaking are summarized as follows:
    Federal Action
    64 Fed. Reg. 50556
    (September 17, 1999)
    64 Fed. Reg. 67450
    (December 1, 1999)
    Summary
    Revisions to the Unregulated Contaminant Monitoring
    Regulation for Public Water.
    The USEPA adopted
    amendments requiring public water supplies to
    monitor for unregulated drinking water
    contaminants. The USEPA adopted the
    amendments under section 1445(a) of SDWA.
    National Primary and Secondary Drinking Water
    Regulations: Analytical Methods for Chemical and
    Microbiological Contaminants and Revisions to Laboratory
    Certification Requirements.
    The USEPA amended the
    rules setting forth the analytical methods
    approved for use in demonstrating compliance
    with the SDWA requirements.
    Public Comments Received
    The Board adopted a proposal for public comment in this matter by order dated June 8,
    2000. The “Notices of Proposed Amendments” appeared in the June 30, 2000 issue of the
    Illinois
    Register
    at 24 Ill. Reg. 8728. The Board accepted public comments on the proposal for a 45-day
    period following publication in the
    Illinois Register.
    The comment period expired on August 15,
    2000.
    The Board received four comments during the public comment (PC) period. Those
    comments are as follows:
    PC 1
    Identical First Notice Line Numbered Version of proposed amendments from JCAR
    (received June 29, 2000).
    PC 2
    July 24, 2000 memo from Deborah Connelly, JCAR (received July 25, 2000).
    PC 3
    August 9, 2000 letter from David S. Horak, Safe Drinking Water Branch, USEPA,
    Region 5 (received August 15, 2000).
    PC 4
    August 14, 2000 letter from Lou Allyn Byus, Assistant Manager - Field Operations,
    Division of Water Supplies, Illinois EPA (received August 18, 2000).
    3
    These public comments are discussed in more detail later in this opinion.
    Response to JCAR Additional Questions
    In addition to PC 1, the Board received public comment from JCAR in PC 2, which
    included two inquiries from JCAR. It is more efficient to address these questions here, rather than
    later. The first question addressed incorporating by reference certain sections of the unregulated
    contaminant monitoring regulations, as proposed by the Board. As the Board is not adopting the
    proposed program in response to Illinois Environmental Protection Agency (Agency) and USEPA
    comments that the proposed rules were not federally required to be adopted as IIS rules, the issue
    is no longer relevant.
    The second question in PC 2 addressed a section of the Board’s June 8, 2000 proposal for
    public comment, appearing at page 4. The section reads as follows:
    Board Amendments not Directly Federally Driven
    The Board is updating all C.F.R. citations in the affected sections of this rulemaking to the
    1999 version. The Board is also amending Section 611.310(a) and the Section 611.310(c)
    Board Note to correct any ambiguity in the regulations for the purpose of avoiding
    confusion to the regulated community. Section 611.310 is applicable to all public water
    systems. The Board is also making numerous technical changes suggested by JCAR, the
    USEPA, and the Agency.
    JCAR questioned the Board’s authority to make such changes. JCAR’s inquiry points out
    that the Board’s caption of this portion of the opinion is not precisely accurate, and is in need of
    revision.
    In every IIS rulemaking, the Board makes various necessary changes to any Section of the
    Administrative Code that may be open as a result of USEPA actions taken during the update
    period. The Board updates references to the most recent version of the C.F.R. and various statutes
    and ensures that the regulations are consistent with the requirements of the C.F.R. The Board also
    corrects any spelling or punctuation errors that may be present. The Board performs these
    functions to provide the regulated community with cost effective and accurate regulations. JCAR
    also suggests changes to the regulations that are not a result of the most recent federal amendments.
    Section 17.5 of the Act mandates that the Board adopt regulations that are “identical in
    substance” to the Primary Drinking Water regulations. 415 ILCS 5/17.5 (1998). If the Board
    could not make corrections to the regulations of the type described above to correct any observed
    error, omission, or lack of conformity with rules of the Secretary of State, the Illinois regulations
    would not become or remain “identical in substance” to the federal regulations.
    Section 7.2(a) of the Act contemplates the necessity of such changes in the third sentence,
    in which it directs that “the only changes that may be made by the Board to the federal regulations
    are those changes that in no way change the scope or meaning of any portion of the regulations.”
    4
    415 ILCS 5/7.2(a) (1998). The Board finds that the changes described in the quoted passage of the
    opinion above are well within its statutory authority, and the Board will continue to make them in
    its IIS rulemakings. However, acknowledging the misnomer,
    i.e.
    , “Board Amendments not
    Federally Driven” identified by JCAR, the Board will discontinue use of the inaccurate descriptor.
    Beginning with this opinion, and in those hereafter, the Board will label the portion of the opinion
    describing such changes as “Additional Technical Changes Authorized by Section 7.2(a).”
    DISCUSSION
    September 17, 1999: Revisions to the Unregulated Contaminant Monitoring Regulation for Public
    Water
    Federal Action
    The Safe Drinking Water Act (SDWA)(42 USC §§ 300f
    et seq
    . (1998)), as amended in
    1996, requires the USEPA to establish criteria for a program to monitor for unregulated
    contaminants and, by August, 1999 to publish a list of contaminants to be monitored. The USEPA
    promulgated the Unregulated Contaminant Monitoring Regulation (UMCR) for Public Water
    Systems (PWSs), which significantly revises the existing regulations for unregulated contaminant
    monitoring. The amendments include a list of contaminants to monitor for, procedures for
    selecting a nationwide representative sample of small systems that will be required to monitor,
    and the frequency and schedule for monitoring, the sampling points, and the approved analytical
    methods for testing. The USEPA adopted the amendments under Section 1445(a) of SDWA (42
    USC §§ 300j-4 (1998)).
    Amendments to Board Rules
    The Board proposed incorporating the bulk of these amendments into its rules by adding Sections 611.511,
    611.512, and 611.Appendix I. However, as a result of the public comments of the USEPA and the Agency, the Board
    is not including these amendments into this final rulemaking. The adoption of the unregulated contaminant
    monitoring program is not necessary for State primacy. For a more detailed discussion on the reasoning behind the
    omission of the unregulated contaminant monitoring program, see the “Public Comments” section below.
    December 1, 1999: Revisions to National Primary and Secondary Drinking Water Regulations:
    Analytical Methods for Chemical and Microbiological Contaminants and Revisions to Laboratory
    Certification Requirements.
    Federal Action
    The USEPA approved the use of updated versions of 25 American Society for Testing and
    Materials (ASTM), 54 Standard Methods for Examination of Water and Wastewater Methods
    (Standard Methods), and 13 USEPA analytical methods (USEPA Methods) for compliance
    determinations of chemical contaminants in drinking water. At the same time, the USEPA
    withdrew approval of 13 previous versions of the USEPA Methods. The USEPA also approved
    the use of a new medium and 2 new methods for simultaneous determination of total coliforms and
    E. coli
    . The USEPA also approved new methods of determination for lead, magnesium, and acid
    herbicides. The USEPA made several technical corrections to existing regulations.
    5
    Amendments to Board Rules
    The Board is amending its regulations for coliform sampling in Section 611.526, and
    methods incorporated by reference in Section 611.102. In Section 611.526 microbiological
    monitoring analytical methods, the Board adds tests set forth under the Standard Methods 19th
    edition. The Board also adds the E*Colite® Test (Charm Sciences, Inc.) and the m-ColiBlue24®
    Test (Hatch Company).
    The Board is amending regulations incorporated by reference for inorganic chemical
    sampling and analytical requirements in Section 611.102. The Board is amending its regulations
    for analytical methods or organic chemical contaminants in Section 611.645 and regulations
    incorporated by reference in Section 611.102. In Section 611.645 the Board is adding analytical
    methods that the USEPA added. The Board is also amending its regulations for volatile organic
    chemicals in Section 611.646 and regulations incorporated by reference in Section 611.102. The
    Board amends Section 611.531 to include the Standard Methods 19th edition.
    The Board amends Section 611.490 to require measurements for alkalinity, calcium,
    conductivity, disinfectant residual, orthophosphate, and silica to be performed by a certified
    operator under 35 Ill. Adm. Code 603.103.
    Additional Technical Changes Authorized by Section 7.2(a)
    The Board is updating all C.F.R. citations in the affected sections of this rulemaking to the
    1999 version. The Board is also amending Section 611.310(a) and the Section 611.310(c) Board
    Note to correct any ambiguity in the regulations for the purpose of avoiding confusion to the
    regulated community. Section 611.310 is applicable to all public water systems. The Board is
    also making numerous technical changes suggested by JCAR, the USEPA, and the Agency.
    In PC 1, JCAR submitted a line numbered version of the proposed rule, as it appeared in
    the Illinois Register. Changes in the proposed rule that were made by JCAR prior to publication
    in the Illinois Register were indicated in an accompanying green cover sheet. JCAR highlighted
    various minor technicalities, formatting discrepancies, and misspellings that were corrected by
    JCAR prior to publication. Also, JCAR indicated that it had struck “μg” and had added “mg” four
    times in Section 611.526(f). These changes to the regulations were made in error. The Board
    does not strike the four instances of “μg” currently on file in this final rule.
    In PC 2, JCAR submitted additional suggested changes in a line numbered version of the
    proposed rule. The Board made numerous minor technical changes suggested by JCAR in this
    final rule. The changes include adding and removing punctuation, spacing, capitalization, and
    spelling. The more substantive changes are indicated in the following table of revisions.
    In PC 3, the USEPA submitted comments concerning monitoring and analytical
    requirements. The Board has incorporated these suggestions. The USEPA also stated that since
    revisions to the unregulated contaminant monitoring regulations are not required for primacy, it did
    not review the related proposed amendments.
    6
    In PC 4, the Agency requested that the proposed amendments implementing the unregulated
    contaminant monitoring program be omitted from the final rule. The Agency stated that Illinois is
    not required to adopt these rules in order to maintain primary enforcement authority for the SDWA.
    The Board proposed implementing the unregulated contaminant monitoring program by adding
    Sections 611.511, 611.512, and 611.Appendix I. The Board has omitted these sections in this final
    rule at the request of the Agency. The Agency also noted inconsistencies with respect to certain
    analytical methods. The Board has corrected any inconsistencies.

    BOARD NOTE: USEPA included the P-A Coliform and Colisure Tests for
    testing finished water under the coliform rule, but did not include them for
    the purposes of the surface water treatment rule, under Section 611.531, for
    which quantitation of total coliforms is necessary. For these reasons,
    USEPA included Standard Methods: Method 9221 C for the surface water
    treatment rule, but did not include it for the purposes of the total coliform
    rule, under this Section.

    This subsection corresponds with 40 CFR 141.21(f)(4), which USEPA has marked
    "reserved". This statement maintains structural consistency with the federal
    regulations.
    e)
    Suppliers shall conduct fecal coliform analysis 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 approved methods that use a membrane filter, transfer the total
    coliform-positive culture by one of the following methods: remove the
    membrane containing the total coliform colonies from the substrate with a
    sterile forceps and carefully curl and insert the membrane into a tube of EC
    medium.; (Tthe 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 for 24±2 hours. Gas production of any amount in the inner fermentation
    tube of the EC medium indicates a positive fecal coliform test.
    3)
    EC medium is described in Standard Methods, 18th ed. and 19th ed.:
    Method 9221 E.
    4)
    Suppliers need only determine the presence or absence of fecal coliforms,;
    a determination of fecal coliform density is not required.
    f)
    Suppliers shall conduct analysis of E. coli in accordance with one of the following
    analytical methods, incorporated by reference in Section 611.102:
    35
    1)
    EC medium supplemented with 50 μg/L of MUG (final concentration). EC
    medium is as described in subsection (e) of this Section. MUG may be
    added to EC medium before autoclaving. EC medium supplemented with
    50 μg/L MUG is commercially available. At least 10 mL 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) of this Section 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±2 hours; or
    2)
    Nutrient agar supplemented with 100 μg/L MUG (final concentration).
    Nutrient agar is described in Standard Methods, 18th ed. or 19th ed.:
    Method 9221 B, at pages 9-47 to 9-48. 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 μg/L 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.
    3)
    Minimal Medium ONPG-MUG (MMO-MUG) Test, as set forth in Section
    611.Appendix D. (The Autoanalysis ColiertColilert 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.
    4)
    The Colisure Test (Autoanalysis Colilert System), from Millipore
    Corporation, incorporated by reference in Section 611.102.
    5) The membrane filter method with MI agar.
    6) The E*Colite
    ®
    Test.
    7) The m-ColiBlue24
    ®
    Test.
    g)
    As an option to the method set forth in subsection (f)(3) of this Section, a supplier
    with a total coliform-positive, MUG-negative, MMO-MUG test may further analyze
    the culture for the presence of E. coli by transferring a 0.1 mL, 28-hour MMO-
    36
    MUG culture to EC medium + MUG with a pipet. The formulation and incubation
    conditions of the EC medium + MUG, and observation of the results, are described
    in subsection (f)(1) of this Section.

    BOARD NOTE: Subsection (e) is derived from the table to 40 CFR 141.23(k)(2) (1995) and the
    discussion at 57 Fed. Reg. 31809 (July 17, 1992). Section 611.609 is derived from 40 CFR
    141.23(k) (1995).
    (Source: Amended at 24 Ill. Reg. _______, effective ________)
    Section 611.612
    Monitoring Requirements for Old Inorganic MCLs
    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.
    54
    2)
    Analyses for all CWSs utilizing only groundwater sources must be repeated
    at three-year intervals.
    3)
    This subsection (a)(3) corresponds with 40 CFR 141.23(1)(3) (19941999),
    which requires monitoring for the repealed old MCL for nitrate at a
    frequency specified by the state. The Board has followed the U.S.
    EPAUSEPA lead and repealed that old MCL. This statement maintains
    structural consistency with U.S. EPAUSEPA rules.
    4)
    This subsection (a)(4) corresponds with 40 CFR 141.23(1)(4) (19941999),
    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.
    EPAUSEPA rules.
    b)
    If the result of an analysis made under subsection (a) of this Section 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 pursuant to subsection (b) of this Section
    above, rounded to the same number of significant figures as the old MCL for the
    substance in question, exceeds the old MCL, the supplier shall notify the Agency
    and give notice to the public pursuant to Subpart T of this Part. Monitoring after
    public notification must be at 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) (19941999), which pertains
    to monitoring for the repealed old MCL for nitrate. The Board has followed the
    U.S. EPAUSEPA action and repealed that old MCL. This statement maintains
    structural consistency with U.S. EPAUSEPA rules.
    e)
    This subsection corresponds with 40 CFR 141.23(p) (19941999), which pertains
    to the use of existing data up until a date long since expired. The Board did not
    adopt the original provision in R88-26. This statement maintains structural
    consistency with U.S. EPAUSEPA rules.
    f)
    Except for arsenic, for which analyses must be made in accordance with Section
    611.611, analyses conducted to determine compliance with the old MCLs of
    Section 611.300 must be made in accordance with the following methods,
    incorporated by reference in Section 611.102.

    BOARD NOTE: The provisions of subsections (a) through (f) of this Section above
    derive from 40 CFR 141.23(l) through (p) (19941999), as amended at 59 Fed.
    Reg. 62466 (Dec. 5, 1994). USEPAU.S. EPA removed and reserved 40 CFR
    141.23(q) (formerly 40 CFR 141.23(f)) at 59 Fed. Reg. 62466 (Dec. 5, 1994).
    Subsection (f)(2) of this Section above relates to a contaminant for which
    USEPAU.S. EPA specifies an MCL, but for which it repealed the analytical
    method. Subsections (f)(2) through (f)(4) of this Sectionabove relate exclusively to
    additional state requirements. The Board retained subsections (f)(1), (f)(3), and
    (f)(4) of this Section to set forth methods for the inorganic contaminants for which
    there is a state-only MCL. The methods specified are those set forth in 40 CFR
    143.4(b) (1999), as amended at 59 Fed. Reg. 62471 (Dec. 5, 1994), for
    secondary MCLs. The predecessor to subsections (a) through (e) of this
    Sectionabove were formerly codified as Section 611.601. The predecessor to
    subsection (f) of this Sectionabove was formerly codified as Section 611.606.

    (Source: Amended at 24 Ill. Reg. ______, effective _______)
    Section 611.646 Phase I, Phase II, and Phase V Volatile Organic Contaminants
    Monitoring of the Phase I, Phase II, and Phase V VOCs for the purpose of determining compliance
    with the MCL must be conducted as follows:
    a)
    Definitions. As used in this Section:
    "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 141.24(f)(7), (f)(11), (f)(14)(i), and
    (f)(20) (19941999). This is a "trigger level" for Phase I, Phase II, and Phase V
    VOCs inasmuch as it prompts further action. The use of the term "detect" in this
    sectionSection 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)(20) 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)(20) in favor of the
    more direct language of paragraphs (f)(7) and (f)(11).
    "Method detection limit", as used in subsections (q) and (t) of this Sectionbelow
    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.
    61
    BOARD NOTE: Derived from 40 CFR 136, Appendix B (19941999). The
    method detection limit is determined by the procedure set forth in 40 CFR 136,
    Appendix B. See subsection (t) of this Sectionbelow.
    b)
    Required sampling. Each supplier shall take a minimum of one sample at each
    sampling point at the times required in subsection (u) of this Sectionbelow.
    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, or 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: Subsections (b) and (c) of this Sectionabove derived from
    40 CFR 141.24(f)(1) through (f)(3) (19941999).
    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 VOCs 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) of this Sectionbelow
    has been completed by December 31, 1992, and the supplier did not detect any of
    the Phase I VOCs, including vinyl chloride, Phase II, or Phase V VOCs, then the
    supplier shall take one sample annually beginning in the initial compliance period.
    62
    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) of this Sectionabove 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) of this Sectionabove. 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) of this
    Sectionabove as to 1,2,4-trichlorobenzene.
    BOARD NOTE: Derived from 40 CFR 141.24(f)(7) and (f)(10) (19941999), 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) of this Sectionbelow.
    The definition of "detect", parenthetically added to the federal counterpart
    paragraph, is in subsection (a) of this Sectionabove.
    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) of
    this Sectionabove sought pursuant to subsection (g) of this Sectionabove.
    i)
    A SEP issued to a GWS pursuant to subsection (g) of this Sectionabove is for a
    maximum of six years, except that a SEP as to the subsection (d) of this
    Sectionabove monitoring for 1,2,4-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) of this Sectionabove 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) of this Sectionabove and submitted pursuant to subsection (g) of this
    Sectionabove, by taking one sample at each sampling point and reapplying for a
    SEP pursuant to subsection (g) of this Sectionabove. 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,
    2)
    Issue a new SEP requiring the supplier to sample annually.
    BOARD NOTE: This provision does not apply to SWSs and mixed
    systems.
    63
    j)
    Special considerations for SEPs for SWSs 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) of this Sectionabove 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 VOCs 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 GWSs, and 40 CFR
    141.24(f)(10), the provision for SWSs. The Board has consolidated the
    common requirements of both paragraphs into subsection (g) of this
    Sectionabove. Subsection (j) of this Sectionabove represents the elements
    unique to SWSs and mixed systems, and subsection (i) of this Sectionabove
    relates to GWSs. Although 40 CFR 141.24(f)(7) and (f)(10) 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 shall be required.
    A)
    The Agency shall grant a SEP pursuant to Section 611.110 that
    allows a supplier to reduce the monitoring frequency to annually 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 SEPs that allow less frequent
    monitoring based on an Agency "reliably and consistently"
    64
    determination shall include a condition requiring the supplier to
    resume quarterly monitoring pursuant to subsection (k)(1) of this
    Sectionabove if it violates the MCL specified by Section 611.311.
    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) of this
    Sectionabove.
    5)
    A GWS supplier that has detected one or more of the two-carbon
    contaminants listed in subsection (k)(5)(A) of this Sectionbelow shall
    monitor quarterly for vinyl chloride as described in subsection (k)(5)(B) of
    this Sectionbelow, subject to the limitation of subsection (k)(5)(C) of this
    Sectionbelow.
    A)
    Two-carbon contaminants (Phase I or II VOC):
    1,2-Dichloroethane (Phase I)
    1,1-Dichloroethylene (Phase I)
    cis-1,2-Dichloroethylene (Phase II)
    trans-1,2-Dichloroethylene (Phase II)
    Tetrachloroethylene (Phase II)
    1,1,1-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) of this Sectionabove.
    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 the first sample required by subsection (k)(5)(B)
    of this Sectionabove.
    l)
    Quarterly monitoring following MCL violations.
    1)
    Suppliers that violate an MCL for one of the Phase I VOCs, including vinyl
    chloride, Phase II, or Phase V VOCs, as determined by subsection (o) of
    this Sectionbelow, shall monitor quarterly for that contaminant, at the
    65
    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 SEPs 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 (l)(1) of this
    Sectionabove 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 VOCs 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 (o) of this Sectionbelow.
    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 141.24(f)(14), an optional USEPA
    provision relating to compositing of samples that USEPA does not require for state
    programs. This statement maintains structural consistency with USEPA rules.
    o)
    Compliance with the MCLs for the Phase I, Phase II, and Phase V VOCs must be
    determined based on the analytical results obtained at each sampling point.
    66
    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 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.
    p)
    This provision corresponds with 40 CFR 141.24(f)(16) (19941999), which
    USEPA removed and reserved at 59 Fed. Reg. 62468 (Dec. 5, 1994). This
    statement maintains structural consistency with the federal regulations.
    q)
    Analysis under this Section must only be conducted by laboratories that have
    received certification by USEPA or the Agency according to the following
    conditions:
    1)
    To receive certification to conduct analyses for the Phase I VOCs,
    excluding vinyl chloride, Phase II VOCs, and Phase V VOCs, the laboratory
    must:
    A)
    Analyze performance evaluation samples that include these
    substances provided by the Agency pursuant to 35 Ill. Adm. Code
    183.125(c)35 Ill. Adm. Code Part 186;
    B)
    Achieve the quantitative acceptance limits under subsections
    (q)(1)(C) and (q)(1)(D) of this Sectionbelow for at least 80 percent
    of the Phase I VOCs, excluding vinyl chloride, Phase II VOCs,
    except vinyl chloride, or Phase V VOCs;
    67
    C)
    Achieve quantitative results on the analyses performed under
    subsection (q)(1)(A) of this Sectionabove that are within ± 20
    percent of the actual amount of the substances in the performance
    evaluation sample when the actual amount is greater than or equal to
    0.010 mg/L;
    D)
    Achieve quantitative results on the analyses performed under
    subsection (q)(1)(A) of this Sectionabove that are within ± 40
    percent of the actual amount of the substances in the performance
    evaluation sample when the actual amount is less than 0.010 mg/L;
    and
    E)
    Achieve a method detection limit of 0.0005 mg/L, according to the
    procedures in 40 CFR 136, appendix B, incorporated by reference
    in Section 611.102.
    2)
    To receive certification to conduct analyses for vinyl chloride the
    laboratory must:
    A)
    Analyze performance evaluation samples provided by the Agency
    pursuant to 35 Ill. Adm. Code 183.125(c)35 Ill. Adm. Code Part
    186;
    B)
    Achieve quantitative results on the analyses performed under
    subsection (q)(2)(A) of this Sectionabove that are within ± 40
    percent of the actual amount of vinyl chloride in the performance
    evaluation sample;
    C)
    Achieve a method detection limit of 0.0005 mg/L, according to the
    procedures in 40 CFR 136, appendix B, incorporated by reference
    in Section 611.102; and
    D)
    Obtain certification pursuant to subsection (q)(1) of this
    Sectionabove for Phase I VOCs, excluding vinyl chloride, Phase II
    VOCs, and Phase V VOCs.
    r)
    Use of existing data.
    1)
    The Agency shall allow the use of data collected after January 1, 1988 but
    prior to the effective date of this 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, Phase II, or Phase V
    68
    VOCs using existing data allowed pursuant to subsection (r)(1) of this
    Sectionabove.
    s)
    The Agency shall, by SEP, increase the number of sampling points or the frequency
    of monitoring if it determines that it is necessary to detect variations within the
    PWS.
    t)
    Each laboratory certified for the analysis of Phase I, Phase II, or Phase V VOCs
    pursuant to subsection (q)(1) or (q)(2) of this Sectionabove shall:
    1)
    Determine the method detection limit (MDL), as defined in 40 CFR 136,
    Appendix B, incorporated by reference in Section 611.102, at which it is
    capable of detecting the Phase I, Phase II, and Phase V VOCs; and,
    2)
    Achieve an MDL for each Phase I, Phase II, and Phase V VOC that is less
    than or equal to 0.0005 mg/L.
    u)
    Each supplier shall monitor, within each compliance period, at the time designated
    by the Agency by SEP pursuant to Section 611.110.
    BOARD NOTE: Derived from 40 CFR 141.24(f) (19941999).
