    (Identical-in-Substance Rulemaking -
    Public Water Supplies)
    Proposed Rule. Proposal for Public Comment.
    OPINION AND ORDER OF THE BOARD (by R.C. Flemal):
    BACKGROUND
    The Board today is proposing for public comment amendments to 35 Ill. Adm. Code Part 611,
    Primary Drinking Water Standards, in response the United States Environmental Protection Agency’s
    (USEPA) amendments of corresponding federal regulations found at 40 C.F.R. §§ 141 and 142. The
    Board is proposing to add the requirement that certain public water systems monitor for unregulated
    drinking water contaminants and is also adding analytical methods approved for determining compliance
    with the drinking water regulations.
    Under Section 17.5 of the Environmental Protection Act (Act) (415 ILCS 5/17.5 (1998)), the
    Board proposes amendments to the Illinois regulations that are “identical in substance” to the National
    Primary Drinking Water regulations (NPDWRs) adopted by 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). The nominal timeframe of this docket includes
    SDWA amendments that the USEPA adopted in the period July 1, 1999, through December 31, 1999.
    The USEPA took two actions during the nominal timeframe period that necessitate Board action. The
    federal SDWA regulations are found at 40 C.F.R. §§ 141 and 142.
    Section 17.5 provides for quick adoption of regulations that are “identical in substance” (IIS) 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 also provides that Title VII of the Act 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.
    Section 7.2(b) of the Act (415 ILCS 5/7.2 (1998)) requires the Board to complete its
    identical-in-substance 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.

    2
    FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING
    This proposed 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 incorporates both
    of these actions.
    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.
    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 adopted
    amendments includes a list of contaminants to be monitored, procedures for selecting a nationwide
    representative sample of small systems that will be required to monitor, the frequency and schedule for

    3
    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 incorporates the bulk of these amendments into its rules by adding Sections
    611.511, 611.512, and 611.Appendix I. The rest of the amendments require only minimal
    changes to existing Illinois regulations.
    New Section 611.511 regulates the reporting of the unregulated contaminant monitoring
    results, and applies to any PWS that is required to monitor under existing Section 611.510.
    The regulations contain a detailed list of the information that PWSs must include in a report
    made to the USEPA and the Agency. The public must also be notified pursuant to Subpart U
    (Consumer Confidence Reports) and Subpart T (Public Notification) of Part 611.
    New Section 611.512 regulates the monitoring requirements for unregulated
    contaminants. The regulations differentiate between the various types of PWSs: large systems
    (serving more than 10,000 persons), small systems (serving 10,000 or fewer persons), and
    whether the PWS purchases its water supply from another PWS. The Board is proposing to
    incorporate by reference certain unregulated contaminant monitoring tables relied upon by the
    USEPA and PWS’s in this proposal and invites public comment. Small systems selected for
    monitoring under the federal monitoring plan, including the State Monitoring Plan, Screening
    Survey, or Pre-Screen Testing, must conduct unregulated contaminant monitoring.
    New Section 611.Appendix I sets forth the quality control requirements for testing
    samples collected. The appendix regulates the quality control requirements for samples
    collected pursuant to new Section 611.512.
    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) 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.
    Amendments to Board Rules

    4
    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.
    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.
    PUBLIC COMMENTS
    The Board will accept public comments in this matter for a period of 45 days after publication
    of the proposed amendments in the
    Illinois Register
    . After the expiration of the 45-day public
    comment period, the Board will proceed to adoption of the regulations based on this proposal on or
    before the September 17, 2000 completion date specified by Section 7.2(b) of the Act.

    a copy must be provided to the Agency. The public shall be notified of the monitoring
    results as provided in Subpart U (Consumer Confidence Reports) and Subpart T
    (Public Notification) of this Part.
    c) The results of unregulated contaminant monitoring shall be reported within 30 days
    following the month in which the results from the laboratory are received.
    d) The report shall contain the following information specified for each sample, and for
    each spiked sample and spike duplicate sample analyzed for quality control purposes
    and associated with each sample and its sample batch:
    1) PWS Identification Number. The code used to identify each PWS. The code
    begins with the standard two-character postal State abbreviation; the remaining
    seven characters are unique to each PWS.
    2) PWS Facility Identification Number for the Source, Treatment Plant, and
    Sampling Point. An identification number established by the Agency, or, at the
    Agency's discretion, the PWS, that is unique to the system for an intake for

    32
    each source of water, a treatment plant and a sampling point. Within each
    PWS, each intake, treatment plant and sampling point must receive a unique
    identification number, including, for intake; surface water intake, ground water
    well or wellfield centroid; and including, for sampling point; entry points to the
    distribution system, wellhead, intake, locations within the distribution system, or
    other representative sampling point specified by the Agency. The same
    identification number must be used consistently throughout the history of
    unregulated contaminant monitoring to represent the facility.
    3) Sample Collection Date. The date the sample is collected reported as 4-digit
    year, 2-digit month, and 2-digit day.
    4) Sample Identification Number. A numeric value assigned by the PWS or
    laboratory to uniquely identify a specific sampling occurrence.
    5) Contaminant/Parameter. The unregulated contaminant or water quality
    parameter for which the sample is being analyzed.
    6) Analytical Results Sign. An alphanumeric value indicating whether the sample
    analysis result was:
    A) (<) “less than”, which means the contaminant was not detected or was
    detected at a level “less than” the minimum reporting level (MRL); or
    B) (=) “equal to”, which means the contaminant was detected at a level
    “equal to” the value reported in “Analytical Result Value.”
    7) Analytical Result Value. The actual numeric value of the analysis for chemical
    and microbiological results, or the MRL if the analytical result is less than the
    specified contaminant's MRL.
    8) Analytical Result Unit of Measure. The unit of measurement for the analytical
    results reported (e.g., micrograms per liter, (
    μ
    g/L); colony-forming units per
    milliliter, (CFU/mL), etc.).
    9) Analytical Method Number. The identification number of the analytical method
    used.
    10) Sample Analysis Type. The type of sample collected. Permitted values include:
    A) Field Sample. The sample collected and submitted for analysis under
    this rule.

    33
    B) Batch Spike/Spike Duplicate. Samples associated with a batch used
    for calculating analytical precision and accuracy. A batch is defined as
    the set of field samples plus one spiked sample and one spiked
    duplicate sample analyzed for contaminant concentrations
    11) Sample Batch Identification Number. The number assigned by the laboratory
    to the batch of samples analyzed with the spiked sample (at the spiking
    concentration reported), to be reported as 9-digit laboratory number (assigned
    by the Agency or the USEPA), 4-digit year, 2- digit month, 2-digit day and 2-
    digit batch number.
    12) Detection Level. Detection level refers to the detection limit applied to both the
    method and equipment. Detection limit is the lowest concentration of a target
    contaminant that a given method or piece of equipment can reliably ascertain
    and report as greater than zero ( e.g., Instrument Detection Limit, Method
    Detection Limit, or Estimated Detection Limit).
    13) Detection Level Unit of Measure. The unit of measure to express the
    concentration, count, or other value of a contaminant level for the detection level
    reported (e.g.,
    μ
    g/L, CFU/mL, etc.).
    14) Analytical Precision. Analytical Precision is the degree of agreement among a
    set of repeated measurements and is monitored through the use of replicate
    samples or measurements. Analytical Precision is defined as the relative percent
    difference (RPD) between spiked matrix duplicates. The RPD for the spiked
    matrix duplicates analyzed in the same batch of samples as the analytical result
    being reported is to be entered in this field. Analytical Precision is calculated as
    RPD between spiked matrix duplicates, using RPD = [(X
    1
    - X
    2
    ) / (X
    1
    + X
    2
    )/2]
    x 100.
    15) Analytical Accuracy. Analytical Accuracy describes how close a result is to the
    true value measured through the use of spikes, standards, surrogates or
    performance evaluation samples. For purposes of unregulated contaminant
    monitoring, accuracy is defined as the percent recovery of the contaminant in
    the spiked matrix sample analyzed in the same analytical batch as the sample
    result being reported and calculated, using % recovery = [(amt. found in spiked
    sample - amt. found in sample) / amt. spiked] x 100.
    16) Spiking Concentration. The concentration of method analytes added to a
    sample to be analyzed for calculating analytical precision and accuracy where
    the value reported use the same unit of measure reported for Analytical Results.
    17) Presence/Absence.

    34
    A) Chemicals. Presence: a response was produced by the analysis (i.e.,
    greater than or equal to the MDL but less than the MRL); Absence: no
    response was produced by the analysis (i.e., less than the MDL).
    B) Microbiologicals. Presence: indicates a response was produced by the
    analysis; Absence: indicates no response was produced by the analysis.
    e) This information shall be reported in the electronic or other format specified by the
    USEPA or the Agency.
    f) The laboratory to which samples are sent may report the results, as long as the
    laboratory sends the PWS a copy for review and recordkeeping. The PWS is
    responsible for the reporting of this information and ensuring that the laboratory reports
    the results to the USEPA, with a copy to the Agency.
    g) Previously collected data to meet the testing and reporting requirements for the
    contaminants listed in Section 611.510 may be reported as long as the data meets the
    specific requirements of Section 611.510 and the data includes the information specified
    in subsection (d) of this Section.

    c)
    Suppliers shall conduct total coliform analyses in accordance with one of the following
    analytical methods, incorporated by reference in Section 611.102 (the time from sample

    42
    collection to initiation of analysis may not exceed 30 hours, and the supplier is
    encouraged but not required to hold samples below 10° C during transit):
    1)
    Multiple-TubeTotal Coliform Fermentation (MTF) Technique, as set forth in
    Standard Methods, 18th or 19th ed.: Methods 9221 A and B:
    A)
    Lactose broth, as commercially available, may be used in lieu of lauryl
    tryptose broth if the supplier conducts at least 25 parallel tests between
    this medium and lauryl tryptose broth using the water normally tested
    and this comparison demonstrates that the false-positive rate and false
    negative rate for total coliforms, using lactose broth, is less than 10
    percent;
    B)
    If inverted tubes are used to detect gas production, the media should
    cover these tubes at least one-half to two-thirds after the sample is
    added; and

    ONPG-MUG test is also known as the autoanalysis colilert system.)
    5)
    Colisure Test (Autoanalysis Colilert System)from Millipore Corporation,
    incorporated by reference in Section 611.102. (The Colisure Test must be
    incubated for 28 hours before examining results. If an examination of the results
    at 28 hours is not convenient, then results may be examined at any time between
    28 hours and 48 hoursmay be read after an incubation time of 24 hours.)
    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

    43
    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

    ®
    Test (Hatch Company)
    d)
    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. (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 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:

    44
    1)
    EC medium supplemented with 50 mg/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 mg/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 mg/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 mg/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 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.
    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.

    45
    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-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.
    h)
    This subsection corresponds with 40 CFR 141.21(f)(8), a central listing of all
    documents incorporated by reference into the federal microbiological analytical
    methods. The corresponding Illinois incorporations by reference are located at Section
    611.102. This statement maintains structural parity with USEPA regulations.

    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.
    2)
    Analyses for all CWSs utilizing only groundwater sources must be repeated at
    three-year intervals.
    3)
    This subsection corresponds with 40 CFR 141.23(1)(3) (1994), 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 corresponds with 40 CFR 141.23(1)(4) (1994), 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 analyses 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) (1994), 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.

    65
    e)
    This subsection corresponds with 40 CFR 141.23(p) (1994), 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. EPA
    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.
    1)
    Fluoride: The methods specified in Section 611.611(c) shall apply for the
    purposes of this Section.

    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). U.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 U.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.

    BOARD NOTE: Derived from 40 CFR 141.24(e) (19951999).
    (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:

    71
    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.
    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.

    72
    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: 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.
    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.

    73
    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.
    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) 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

    74
    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
    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 (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):

    75
    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 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.

    76
    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.
    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.

    77
    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) (1994), 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);
    B)

    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

    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);

    78
    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;

    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
    VOC 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.

    611.Appendix I Quality Control Requirements for Testing All Samples Collected
    Public Water Systems shall ensure that the quality control requirements for testing of samples collected
    and submitted under Section 611.512 are followed:
    a) Sample Collection/Preservation. Systems shall follow the sample collection and preservation
    requirements for the specified method for each of the contaminants in Table 1, Unregulated
    Contaminant Monitoring Regulation (1999) List. These requirements specify sample containers,
    collection, dechlorination, preservation, storage, sample holding time, and extract storage and/or
    holding time that the laboratory must follow.
    b) Method Detection Limit. Systems shall calculate the laboratory method detection limit (MDL)
    for each contaminant in Table 1, Unregulated Contaminant Monitoring Regulation (1999) List,
    using the appropriate specified method according to procedures in 40 CFR Part 136, Appendix
    B, with the exception that the contaminant concentration used to fortify reagent water must be
    less than or equal to the minimum reporting level (MRL) for the contaminants as specified in
    Table 1, Unregulated Contaminant Monitoring Regulation (1999) List, Column 4. The
    calculated MDL is equal to the standard deviation times the Student's T value for 99%
    confidence level with n-1 degrees of freedom. (The MDL must be less than or equal to one-half
    of the MRL.)
    c) Calibration. Systems shall follow the initial calibration requirements as specified in the method
    utilized. Calibration must be verified initially with a low-level standard at a concentration at or
    below the MRL for each contaminant. Systems shall perform a continuing calibration
    verification following every 10th sample. The calibration verification must be performed by
    alternating low-level and mid-level calibration standards. The low-level standard is defined as a
    concentration at or below the MRL with an acceptance range of
    ±
    40%. The mid-level
    standard is in the middle of the calibration range with an acceptance range of
    ±
    20%.
    d) Reagent Blank Analysis. Systems shall analyze one laboratory reagent (method) blank per
    sample set/batch that is treated exactly as a sample. The maximum allowable background
    concentration is one-half of the MRL for all contaminants. A field reagent blank is required only
    for EPA Method 524.2 (or equivalent listed methods, D5790.95, SM6210D, and SM6200B).
    e) Quality Control Sample. Systems shall obtain a quality control sample from an external source
    to check laboratory performance at least once each quarter.
    f) Matrix Spike and Duplicate. Systems shall prepare and analyze the sample matrix spike (SMS)
    for accuracy and matrix spike duplicate (MSD) samples for precision to determine method
    accuracy and precision for all contaminants in Table 1, Unregulated Contaminant Monitoring

    80
    Regulation (1999) List. SMS/MSD samples must be prepared and analyzed at a frequency of
    5% (or one SMS/MSD set per every 20 samples) or with each sample batch, whichever is
    more frequent. In addition, the SMS/MSD spike concentrations must be alternated between a
    low-level spike and mid-level spike approximately 50% of the time. (For example: a set of 40
    samples will require preparation and analysis of two SMS/MSD sets. The first set must be
    spiked at either the low-level or mid level, and the second set must be spiked with the other
    standard, either the low-level or mid-level, whichever was not used for the initial SMS/MSD
    set). The low-level SMS/MSD spike concentration must be within
    ±
    20% of the MRL for each
    contaminant. The mid-level SMS/MSD spike concentration must be within
    ±
    20% of the mid-
    level calibration standard for each contaminant, and should represent, where possible, an
    approximate average concentration observed in previous analyses of that analyte. The spiking
    concentrations must be reported in the same units of measure as the analytical results.
    g) Internal Standard Calibration. Systems shall, as appropriate to a method's requirements to be
    used, test and obtain an internal standard for the methods for each chemical contaminant in
    Table 1, Unregulated Contaminant Monitoring Regulation (1999) List, a pure contaminant of
    known concentration, for calibration and quantitation purposes. The methods specify the
    percent recovery or response that must be obtained for acceptance.
    h) Method Performance Test. Systems shall, as appropriate to a method's requirements, test for
    surrogate compounds, a pure contaminant unlikely to be found in any sample, to be used to
    monitor method performance. The methods specify the percent recovery that must be obtained
    for acceptance.
    i) Detection Confirmation. Systems shall confirm any chemical contaminant detected above the
    MRL by gas chromatographic/mass spectrometric (GC/MS) methods. If testing resulted in first
    analyzing the sample extracts via specified gas chromatographic methods, an initial confirmation
    by a second column dissimilar to the primary column may be performed. If the contaminant
    detection is confirmed by the secondary column, then the contaminant must be reconfirmed by
    GC/MS using three specified ion peaks for contaminant identification. One of the following
    confirming techniques must be used: perform single point calibration of the GC/MS system for
    confirmation purposes only as long as the calibration standard is at a concentration within
    ±
    50% of the concentration determined by the initial analysis; or perform a three point calibration
    with single point daily calibration verification of the GC/MS system regardless of whether that
    verification standard concentration is within
    ±
    50% of sample response. If GC/MS analysis
    confirms the initial contaminant detection, report results determined from the initial analysis.
    j) Reporting. Systems shall report the analytical results and other data with the required data listed
    in Section 611.511. Systems shall report this data electronically to the USEPA, unless the
    USEPA specifies otherwise, and must provide a copy to the Agency. Systems must coordinate
    with their laboratories for electronic reporting to the USEPA to ensure proper formatting and
    timely data submission.
