    that remove
    particulate
    matter
    larger than one
    micrometer
    using an engineered
    porous
    filtration
    media.
    They
    are typically
    constructed
    of
    a
    non-rigid, fabric
    filtration
    media
    housed in
    a
    pressure
    vessel in which the
    direction
    of flow is
    from the inside
    of the
    bag
    to
    outside.
    “Bank
    filtration” means
    a water treatment
    process
    that uses

    infiltrated
    into
    groundwater
    through
    a
    river
    bed
    or banks.
    Infiltration
    is typically enhanced

    4)
    that is
    assigned
    to a filtered
    system supplier
    pursuant
    to Section
    611.1010
    based on the
    results
    of the source
    water Cryptosporidium
    monitoring described
    in
    the
    previous section.
    This bin classification
    determines
    the degree of
    additional
    Cryptosporidium
    treatment, if
    any,
    the filtered PWS
    must provide.

    media. They are
    typically
    constructed
    as
    rigid
    or semi-rigid,
    self-
    supporting
    filter
    elements housed
    in
    pressure
    vessels in which
    flow is from
    the
    outside of
    the cartridge
    to the inside.
    “CAS No.”

    first
    customer,
    and
    the
    corresponding
    “disinfectant
    contact
    time”
    CT)
    in minutes.
    If a
    supplier
    applies
    disinfectants
    at more than
    one point prior
    to the first
    customer,
    it
    must
    determine
    the CT of
    each
    disinfectant
    sequence before
    or
    at
    the first customer
    to determine the
    total
    percent
    inactivation or “total
    inactivation
    ratio.”
    In
    determining the
    total
    inactivation
    ratio, the supplier
    must determine
    the RDC
    of
    each
    disinfection
    sequence
    and corresponding
    contact time
    before
    any subsequent
    disinfection
    application
    points.
    (See
    “CT99.9.”)
    “CT99.9”
    is
    the
    CT
    value
    required
    for
    99.9
    percent
    (3-log) inactivation
    of
    Giardia lamblia cysts.
    CT99.9 for
    a variety
    of
    disinfectants
    and conditions
    appear
    in Tables 1.1-1.6,
    2.1 and 3.1 of
    Appendix
    B
    of this
    Part.
    (See
    “Inactivation
    Ratio.”)
    BOARD NOTE:
    Derived
    from
    the
    definition of
    “CT’ in
    40 CFR 141.2
    (2006)
    (2007)
    “Coagulation” means
    a process using
    coagulant chemicals
    and mixing
    by which
    colloidal
    and suspended
    materials are
    destabilized
    and agglomerated
    into
    flocs.
    “Combined
    distribution
    system”
    means the interconnected
    distribution
    system
    consisting
    of
    the distribution systems
    of wholesale
    systems and of
    the
    consecutive
    systems
    that receive finished
    water.
    “Community
    water
    system”
    or “CWS” means a
    public water system
    (PWS)
    that
    serves
    at
    least 15
    service
    connections
    used by year-round
    residents or
    regularly serves
    at least 25
    year-round
    residents.
    BOARD
    NOTE:
    This definition
    differs slightly
    from
    that of
    Section
    3.05
    of the
    Act.
    “Compliance
    cycle”
    means the nine-year
    calendar
    year
    cycle during which
    public
    water systems
    (PWSs)
    must monitor. Each
    compliance
    cycle
    consists of
    three
    three-year
    compliance periods.
    The first
    calendar
    cycle
    began January
    1, 1993,
    and
    ended
    December
    31, 2001;
    the
    second
    began January
    1, 2002,
    and
    ends December
    31, 2010;
    the third
    begins January
    1, 2011,
    and ends
    December 31,
    2019.
    “Compliance
    period” means
    a three-year
    calendar year
    period
    within
    a compliance
    cycle.
    Each
    compliance cycle
    has three
    three-year
    compliance
    periods. Within
    the
    first compliance
    cycle,
    the first compliance
    period ran from
    January
    1, 1993
    to
    December 31,
    1995; the second
    from January
    1, 1996
    to December 31,
    1998;
    the
    third
    from January
    1, 1999
    to
    December
    31,
    2001.
    “Comprehensive
    performance
    evaluation” or
    “CPE” is
    a
    thorough
    review and
    analysis of
    a treatment
    plant’s
    performance-based
    capabilities
    and associated
    administrative,
    operation,
    and maintenance
    practices.
    It
    is
    conducted
    to
    identify
    factors that may
    be adversely
    impacting a
    plant’s
    capability
    to achieve
    compliance
    and
    emphasizes
    approaches
    that
    can
    be
    implemented without
    significant
    capital
    improvements.
    BOARD
    NOTE: The
    final sentence
    of the
    definition of “comprehensive
    performance
    evaluation”
    in

    (2),
    USEPA
    approved the
    method
    as
    described
    in the above
    literature review.
    The method itself
    is embodied in
    the
    printed
    instructions to the
    proprietary kit
    available from IDEXX
    Laboratories,
    Inc.

    SUBPART G:
    LEAD AND COPPER
    Section
    611.350
    General Requirements
    a)
    Applicability and
    Scope
    1)
    Applicability.
    The requirements
    of this
    Subpart G constitute
    national
    primary drinking
    water regulations
    for lead and copper.
    This Subpart
    G
    applies
    to all
    community water
    systems
    (CWS5)
    and non-transient,
    non-community
    water
    systems
    (NTNCWS5)
    2)
    Scope.
    This Subpart G
    establishes
    a
    treatment
    technique
    that includes
    requirements
    for corrosion
    control
    treatment, source
    water treatment,
    lead
    service
    line
    replacement,
    and public
    education. These
    requirements are
    triggered,
    in
    some
    cases,
    by lead and copper
    action levels
    measured in samples
    collected
    at
    consumers’
    taps.
    b)
    Definitions. For
    the purposes
    of only this
    Subpart
    G, the following
    terms
    have
    the following
    meanings:
    “Action level”
    means that
    concentration
    of lead
    or copper in
    water
    computed
    pursuant
    to subsection
    (c)
    of this
    Section
    that
    determines, in
    some
    cases, the
    treatment
    requirements of this
    Subpart
    G
    that
    a supplier must
    complete.
    The action level
    for lead is 0.015
    mg/l. The action
    level for
    copper
    is 1.3
    mg/l.
    “Corrosion inhibitor”
    means a
    substance
    capable
    of reducing the
    corrosivity
    of water
    toward metal plumbing
    materials, especially
    lead and
    copper,
    by
    forming
    a protective
    film on the
    interior surface
    of those materials.
    “Effective
    corrosion
    inhibitor
    residual” means
    a
    concentration
    of
    inhibitor
    in
    the drinking
    water
    sufficient
    to form
    a
    passivating
    film
    on the
    interior
    walls
    of
    a
    pipe.
    “Exceed,”
    as
    this term is
    applied to either
    the
    lead or
    the
    copper action
    level, means
    that the
    90th percentile
    level of the
    supplier’s
    samples
    collected
    during
    a
    six-month monitoring
    period is
    greater than
    the action
    level
    for that
    contaminant.
    “First
    draw
    sample” means a one-liter
    sample
    of
    tap water, collected
    in
    accordance
    with Section
    611.356(b)
    (2),
    that
    has been
    standing
    in plumbing
    pipes
    for
    at
    least
    six hours and
    which is collected
    without flushing
    the tap.
    “Large
    system’
    means
    a
    water
    system that
    regularly serves
    water
    to more
    than 50,000
    persons.
    “Lead
    service line” means
    a
    service
    line made of lead
    that connects
    the
    water
    main
    to
    the building inlet,
    including
    any lead pigtail,
    gooseneck, or
    other fitting
    that
    is connected
    to such lead
    line.
    “Maximum
    permissible
    concentration”
    or
    TTMPCT
    means
    that concentration
    of
    lead
    or copper
    for finished
    water
    entering
    the supplier’s
    distribution
    system,
    designated
    by
    the Agency
    by a
    SEP
    pursuant
    to Sections 611.110
    and 611.353(b)
    that reflects
    the
    contaminant removal
    capability
    of
    the treatment
    properly
    operated and
    maintained.

    fewer persons.
    “Meet,”
    as this term is
    applied
    to
    either the lead
    or the copper
    action
    level, means
    that
    the 90th percentile
    level
    of the supplier’s
    samples collected
    during a
    six-month
    monitoring period
    is less than
    or equal to the
    action level
    for that
    contaminant.
    “Method
    detection limit”
    or “MDL”
    is as defined at
    Section
    611.646(a).
    The MDL
    for
    lead

    c)
    Lead and Copper
    Action
    Levels.
    1)
    The
    lead action
    level is exceeded
    if
    the 90th percentile
    lead
    level
    is
    greater
    than

    is exceeded if
    the
    90th
    percentile
    copper level
    is
    greater than
    1.3 mg/l.
    3)
    Suppliers
    must
    compute the 90th
    percentile lead
    and copper
    levels as
    follows:
    A)
    List
    the results of all
    lead or copper samples
    taken
    during a
    six-month
    monitoring period
    in ascending order,
    ranging from
    the
    sample
    with
    the lowest
    concentration
    first
    to
    the sample with
    the highest concentration
    last.
    Assign
    each
    sampling result
    a
    number, ascending
    by
    single integers
    beginning
    with
    the
    number 1
    for the sample with
    the lowest contaminant
    level.
    The
    number assigned
    to
    the sample
    with the highest
    contaminant level
    must
    be
    equal to the
    total
    number of samples
    taken.
    B)
    Determine the number
    for
    the 90th
    percentile sample
    by
    multiplying the
    total number
    of samples taken
    during
    the six-month
    monitoring
    period by
    0.9.
    C)
    The contaminant
    concentration
    in
    the sample
    with the number yielded
    by the
    calculation
    in subsection
    Cc)
    (3) (B)
    of
    this Section is
    the 90th percentile
    contaminant
    level.
    D)
    For suppliers
    that
    collect five
    samples per
    six-month monitoring
    period,
    the 90th
    percentile
    is
    computed by taking
    the average
    of the highest
    and
    second
    highest
    concentrations.
    E)
    For
    a
    supplier
    that
    has been
    allowed by the
    Agency
    to
    collect
    fewer than
    five
    samples in accordance
    with Section
    611.356(c),
    the
    sample
    result
    with the
    highest
    concentration
    is considered the
    90th percentile
    value.
    d)
    Corrosion
    Control Treatment
    Requirements.
    1)
    All suppliers
    must install and
    operate optimal
    corrosion control
    treatment.

    tap sampling
    (Sections
    611.356
    Cd) (1)
    and 611.357(b))
    until the supplier either
    exceeds the lead action
    level or the copper action
    level or it becomes eligible
    for reduced monitoring
    under Section
    611.356(d)
    (4). A
    supplier exceeding the lead
    action
    level
    or the
    copper action level must recommend optimal
    corrosion control
    treatment
    (Section
    611.352(a))
    within

    perform
    such
    studies, the
    Agency
    must,
    by a SEP issued pursuant
    to Section 611.110,
    specify
    optimal
    corrosion control treatment
    (Section
    611.352(d))
    within
    the appropriate
    of the
    following timeframes:
    A)

    For medium-sized systems, within
    18 months after the end
    of the
    monitoring
    period during which such
    supplier exceeds the lead
    action level or
    the copper
    action level--; or
    B)
    for
    For small systems, within 24
    months after the end of the
    monitoring
    period
    during which such supplier exceeds
    the lead action level
    or the copper
    action level.
    3)
    Step 3:
    If the Agency
    requires a supplier
    to perform corrosion control
    studies under
    step
    2
    (subsection
    (e) (2)
    of this
    Section),
    the supplier must
    complete the studies
    (Section 611.352(c))
    within
    18 months after the Agency
    requires that such
    studies be conducted.
    4)
    Step
    4: If the
    supplier has performed corrosion
    control studies under
    step 2
    (subsection (e) (2)
    of
    this
    Section),
    the Agency
    must, by a SEP issued
    pursuant to Section 611.110, approve
    optimal corrosion
    control treatment
    (Section 611.352(d))
    within six months
    after completion
    of step 3
    (subsection
    (e) (3)
    of this
    Section)
    5)
    Step 5: The supplier must
    install optimal corrosion
    control treatment
    (Section 611.352(e))
    within 24 months
    after the Agency
    approves such treatment.

    Step 6: The supplier must
    complete follow-up sampling
    (Sections
    611.356(d) (2)
    and 611.357(c)) within
    36 months after the Agency
    approves optimal
    corrosion control treatment.
    7)
    Step 7: The Agency must review
    the supplier’s installation
    of treatment
    and, by a SEP issued pursuant
    to Section 611.110, approve optimal
    water quality
    control parameters
    (Section
    611.352(f))
    within six months after
    completion of
    step 6
    (subsection (e) (6)
    of this
    Section)

    Agency
    must, by
    a
    SEP issued
    pursuant
    to
    Section 611.110,
    review
    the supplier’s
    installation
    and
    operation of source
    water treatment
    and

    Section)
    and continue source
    water monitoring
    (Section
    611.358(d)).
    b)
    Description
    of Source
    Water Treatment
    Requirements.
    1)
    System
    treatment recommendation.
    Any
    supplier that
    exceeds the
    lead
    action level or
    the copper action
    level must recommend
    in writing
    to
    the Agency
    the
    installation and
    operation
    of
    one
    of the source water
    treatments listed
    in
    subsection
    (b) (2)
    of this
    Section. A supplier
    may recommend
    that
    no
    treatment
    be installed
    based on a
    demonstration
    that
    source water treatment
    is
    not
    necessary to
    minimize lead
    and copper
    levels
    at
    users’ taps.
    2)
    Agency determination
    regarding
    source water treatment.
    A)
    The
    Agency must
    complete an
    evaluation
    of the results
    of all source water
    samples submitted
    by the
    supplier
    to
    determine
    whether source water
    treatment is
    necessary to minimize
    lead
    or copper levels
    in water
    delivered
    to
    users’
    taps.
    B)
    If the Agency
    determines
    that treatment
    is needed,
    the Agency must,
    by a
    SEP issued
    pursuant
    to
    Section 611.110,
    either
    require installation
    and
    operation of
    the source
    water treatment
    recommended
    by the supplier
    (if
    any) or
    require the installation
    and
    operation
    of another
    source water treatment
    from
    among
    the
    following:
    i)
    ion exchange;
    ii)
    reverse osmosis;
    iii)
    lime softening;
    or
    iv)
    coagulation/filtration.
    C)
    The Agency may request
    and
    the supplier
    must
    submit such additional
    information,
    on or before
    a
    certain
    date,
    as the
    Agency
    determines is
    necessary
    to aid in its
    review.
    D)
    The Agency must
    notify the supplier
    in writing
    of its determination
    and
    set
    forth the basis for
    its decision.
    3)
    Installation
    of source
    water
    treatment.
    Each
    supplier
    must properly
    install and operate
    the source
    water
    treatment approved
    by the
    Agency
    under
    subsection
    (b) (2)
    of this Section.
    4)
    Agency
    review of source
    water
    treatment
    and
    specification
    of maximum
    permissible
    source water
    levels (MPCs)
    A)
    The Agency must
    review
    the
    source
    water samples
    taken by
    the supplier both
    before
    and after the
    supplier
    installs
    source water
    treatment, and
    determine
    whether
    the supplier has
    properly
    installed
    and
    operated
    the approved
    source
    water treatment.
    B)
    Based on its
    review, the
    Agency
    must,
    by
    a
    SEP
    issued pursuant
    to Section
    611.110,
    approve the
    lead and copper MPCs
    for finished water
    entering
    the
    supplier’s
    distribution
    system.
    Such levels
    must reflect
    the
    contaminant
    removal
    capability
    of the
    treatment
    properly
    operated
    and
    maintained.
    C)
    The
    Agency must explain
    the basis for
    its decision
    under subsection
    (b) (4) (B)
    of
    this Section.
    5)
    Continued operation
    and maintenance.
    Each
    supplier must maintain
    lead and
    copper
    levels below the
    MPC5 approved
    by
    the Agency
    at each sampling
    point
    monitored
    in accordance with
    Section 611.358.
    The
    supplier
    is
    out
    of
    compliance
    with this subsection
    if
    the
    level of lead or
    copper at any
    sampling point
    is
    greater than the
    MPC approved by
    the Agency
    pursuant to subsection
    (b)
    (4) (B)
    of
    this
    Section.
    6)
    Modification
    of Agency
    treatment decisions.
    A)
    On its own
    initiative, or
    in response
    to a
    request
    by
    a
    supplier, the
    Agency
    may,
    by a
    SEP
    issued pursuant
    to
    Section
    611.110, modify
    its
    determination
    of the
    source
    water treatment
    under
    subsection
    (b) (2)
    of this
    Section,
    or the lead and
    copper MPCs under
    subsection
    (b)
    (4)
    of this Section.
    B)
    A request
    for modification
    by a supplier must
    be in writing,
    explain
    why
    the
    modification is
    appropriate, and
    provide supporting
    documentation.
    C)
    The Agency
    may, by
    a SEP
    issued
    pursuant
    to Section
    611.110,
    modify its
    determination
    where
    it concludes that
    such
    change
    is necessary
    to
    ensure that
    the
    supplier continues
    to
    minimize lead
    and
    copper
    concentrations
    in
    source
    water.
    D)
    A
    revised
    determination
    made
    pursuant to
    subsection
    (b) (6)
    (C)
    of
    this
    Section
    must set forth
    the
    new
    treatment
    requirements,
    explain
    the basis
    for
    the
    Agency’s
    decision, and
    provide an implementation
    schedule
    for completing
    the
    treatment
    modifications.
    E)
    Any interested person may submit information
    to the Agency, in
    writing,
    that bears on whether the Agency should, within
    its discretion, issue
    a SEP to
    modify its determination pursuant
    to subsection
    (h) (1)
    of this
    Section. An
    Agency determination not to
    act
    on a submission
    of such information
    by an
    interested
    person is not an Agency determination
    for the purposes of
    Sections
    39
    and 40 of the Act
    [415
    ILCS 5/39 and
    401
    7)
    Treatment decisions by IJSEPA. Pursuant
    to the procedures in
    40 CFR
    142.19,
    the USEPA Regional Administrator reserves
    the prerogative
    to review
    treatment determinations made
    by
    the Agency
    under subsections
    (b)
    (2), (b) (4),
    or
    (b) (6)
    of this Section and issue federal
    treatment determinations
    consistent
    with
    the requirements of 40 CFR 141.83
    (b) (2), (b) (4)
    , and
    (b)
    (6),
    where the
    Administrator finds that the following is
    true:
    A)
    the Agency has failed to issue
    a
    treatment
    determination
    by
    the
    applicable
    deadline
    contained in subsection
    (a)
    of this
    Section;
    B)
    the Agency has
    abused its discretion in
    a substantial number of cases
    or
    in
    cases
    affecting
    a substantial population; or
    C)
    the technical
    aspects of the Agency’s
    determination would be indefensible
    in an expected federal enforcement
    action taken
    against a supplier.
    BOARD NOTE:
    Derived
    from 40 CFR 141.83
    (2002)
    (2007),
    as amended at

    , effective
    Section 611.354
    Lead
    Service Line Replacement
    a)
    Suppliers required
    to replace lead service
    lines.
    1)
    If the results from
    tap samples taken pursuant
    to Section
    611.356(d)
    (2)
    exceed the lead action level
    after the supplier has installed
    corrosion control
    or source water treatment
    (whichever
    sampling occurs later),
    the supplier must
    recommence replacing lead service lines
    in accordance with the
    requirements of
    subsection
    (b)
    of this Section.
    2)
    If a
    supplier
    is in violation of Section
    611.351 or Section 611.353
    for
    failure
    to
    install
    source water or corrosion control
    treatment, the Agency
    may,
    by a
    SEP issued pursuant
    to Section 611.110, require the
    supplier to commence
    lead
    service line replacement under
    this Section after the
    date by which the
    supplier was required
    to
    conduct
    monitoring under Section
    611.356
    Cd) (2)
    has
    passed.
    b)
    Annual replacement of lead
    service lines.
    1)
    Initiation of a lead service
    line replacement program.
    A)
    A supplier that is required
    to commence lead service
    line replacement
    pursuant to subsection
    (a)
    of
    this Section must annually
    replace at least seven
    percent of the initial number of lead
    service lines in its distribution
    system.
    2-B)
    The initial number of lead service
    lines is the number of lead lines
    in
    place at the
    time
    the replacement program
    begins.
    C)
    The
    supplier
    must
    identify
    the
    initial
    number
    of lead
    service
    lines
    in its
    distribution
    system,
    including
    an
    identification
    of
    the portions
    of the
    system
    owned
    by
    the
    supplier,
    based
    on a
    materials
    evaluation,
    including
    the evaluation
    required
    under
    Section
    611.356(a)
    and
    relevant
    legal authorities
    (e.g.,
    contracts,
    local
    ordinances)
    regarding
    the
    portion
    owned
    by
    the system.
    4D)
    The
    first year
    of lead
    service
    line
    replacement
    must begin
    on the
    datc
    first
    day
    following
    the
    end
    of the
    monitoring
    period in
    which
    the
    supplier
    exceeded
    the
    action
    level
    in
    tap
    sampling
    rcfcrcnccd
    in
    pursuant
    to subsection
    (a)
    of
    this
    Section.
    E)
    If
    monitoring
    is
    required
    annually
    or less
    frequently,
    the
    end
    of
    the
    monitoring
    period
    is September
    30 of
    the
    calendar
    year
    in
    which the
    sampling
    occurs.
    F)
    If
    the Agency
    has established
    an
    alternate
    monitoring
    period
    by
    a SEP
    issued pursuant
    to
    Section
    611.110,
    then
    the end
    of
    the
    monitoring
    period
    will
    be
    the last
    day
    of
    that
    period.
    2)
    Resumption
    of a
    lead
    service
    line
    replacement
    program
    after
    cessation.
    A)
    A supplier
    that
    is resuming
    a
    program
    after
    cessation
    of its
    lead
    service
    line
    replacement
    program,
    as
    allowed
    pursuant
    to subsection
    (f)
    of
    this
    Section
    must
    update
    its
    inventory
    of
    lead service
    lines
    to include
    those sites
    that
    it
    had previously
    determined
    did
    not
    require
    replacement
    pursuant
    to
    the
    sampling
    provision
    of subsection
    (c)
    of
    this
    Section.
    B)
    The supplier
    will
    then divide
    the
    updated number
    of
    remaining
    lead
    service
    lines
    by the
    number
    of remaining
    years in
    the program
    to
    determine
    the
    number
    of
    lines
    that must
    be
    replaced
    per year
    (seven
    percent
    lead service
    line
    replacement
    is
    based
    on a 15-year
    replacement
    program,
    so
    that,
    for example,
    a
    supplier
    resuming
    lead
    service
    line replacement
    after previously
    conducting
    two
    years
    of replacement
    would
    divide
    the updated
    inventory
    by
    13).
    C)
    For
    a
    supplier
    that
    has completed
    a
    15-year
    lead
    service
    line
    replacement
    program,
    the
    Agency
    must,
    by
    a SEP issued
    pursuant
    to
    Section
    611.110,
    determine
    a
    schedule
    for
    replacing
    or retesting
    lines
    that
    were
    previously
    tested out
    under
    the completed
    replacement
    program,
    whenever
    the
    supplier
    has
    re-exceeded
    the action
    level.
    c)
    Service
    lines
    not
    needing
    replacement.
    A
    supplier
    is
    not required
    to
    replace
    any
    individual
    lead service
    line
    for
    which
    the
    lead concentrations
    in
    all
    service
    line
    samples
    taken
    from that
    line
    pursuant
    to
    Section
    611.356(b)
    (3)
    are
    less
    than or
    equal to
    0.015 mg/l.
    d)
    A water
    supplier
    must replace
    that
    portion
    of the
    lead
    service
    line
    that
    it owns.
    In
    cases
    where
    the
    supplier
    does
    not own
    the
    entire
    lead service
    line,
    the supplier
    must
    notify the
    owner
    of
    the line,
    or
    the
    owner’s
    authorized
    agent,
    that the
    supplier
    will
    replace
    the portion
    of
    the service
    line
    that it
    owns
    and
    must offer
    to
    replace
    the owner’s
    portion
    of the
    line.
    A supplier
    is not
    required
    to
    bear
    the cost
    of replacing
    the
    privately-owned
    portion
    of the line,
    nor
    is it
    required
    to replace
    the
    privately-owned
    portion
    where
    the
    owner
    chooses
    not
    to
    pay
    the
    cost
    of replacing
    the
    privately-owned
    portion
    of the
    line,
    or where
    replacing
    the privately-owned
    portion
    would
    be
    prec]uded
    by
    State,
    local,
    or
    common
    law.
    A water
    supplier
    that
    does
    not
    replace
    the
    entire
    length
    of
    the
    service
    line
    also
    must
    complete
    the following
    tasks:
    1)
    Notice Prior
    to
    Commencement
    of Work.
    A)
    At
    least 45 days prior
    to
    commencing
    the partial replacement
    of
    a lead
    service
    line,
    the
    water supplier must
    provide
    notice to the residents
    of all
    buildings
    served
    by
    the
    line explaining
    that
    they
    may experience
    a
    temporary
    increase
    of
    lead
    levels in
    their drinking
    water,
    along
    with guidance
    on measures
    consumers
    can take to
    minimize
    their exposure
    to lead.
    B)
    The
    Agency,
    by
    issuing an appropriate
    SEP,
    may allow the
    water supplier to
    provide
    notice
    under
    the previous sentence
    less
    than
    45 days prior
    to
    commencing
    partial
    lead service
    line
    replacement where
    it determines
    that such
    replacement
    is
    in
    conjunction
    with emergency
    repairs.
    C)
    In addition,
    the water
    supplier
    must
    inform
    the residents
    served by the
    line that the
    supplier
    will,
    at
    the
    supplier’s expense,
    collect
    a
    sample
    from
    each
    partially-replaced
    lead
    service line
    that is representative
    of the
    water in
    the
    service line for analysis
    of lead
    content, as prescribed
    by
    Section
    611.356(b) (3),
    within
    72 hours after
    the
    completion
    of the partial
    replacement
    of the
    service
    line. The
    supplier
    must collect
    the sample and
    report
    the
    results
    of the analysis
    to
    the owner and
    the residents
    served by the
    line
    within
    three business
    days
    of receiving
    the results.
    D)
    Mailed notices
    post-marked
    within
    three business
    days
    of receiving
    the
    results
    must be considered
    “on time.”
    2)
    The
    water supplier
    must
    provide
    the information
    required
    by
    subsection
    (d) (1)
    of this
    Section
    to
    the
    residents
    of individual
    dwellings
    by
    mail or by
    other methods approved
    by
    the Agency
    by a SEP issued
    pursuant
    to
    Section
    611.110.
    In instances
    where
    multi-family
    dwellings are
    served
    by the
    service
    line,
    the water supplier
    must
    have
    the
    option to post the
    information at a
    conspicuous
    location.
    e)
    Agency determination
    of shorter
    replacement
    schedule.
    1)
    The Agency must,
    by a
    SEP
    issued
    pursuant to Section
    611.110, require
    a
    supplier
    to replace lead
    service
    lines
    on
    a shorter schedule
    than that otherwise
    required by
    this Section if
    it determines,
    taking
    into account
    the number of
    lead service lines
    in the system,
    that
    such a shorter
    replacement schedule
    is
    feasible.
    2)
    The
    Agency must notify
    the
    supplier of its finding
    pursuant
    to
    subsection
    (e) (1)
    of this
    Section
    within six months
    after the
    supplier is
    triggered
    into
    lead
    service line replacement
    based on
    monitoring,
    as referenced in
    subsection
    (a)
    of
    this
    Section.
    f)
    Cessation
    of service line
    replacement.
    1)
    Any supplier may
    cease
    replacing
    lead service lines
    whenever it fulfills
    both of
    the following conditions:
    A)
    First draw
    tap samples
    collected
    pursuant to
    Section
    611.356(b) (2)
    meet
    the
    lead action level
    during each of
    two consecutive
    six-month monitoring
    periods;
    and
    B)
    The supplier
    has submitted those
    results
    to the Agency.

    A)
    IMPORTANT INFORMATION ABOUT LEAD IN YOUR
    DRINKING WATER.
    [INSERT
    NABE OF
    SUPPLIER]
    found elevated levels of lead in drinking water in
    some
    homes/buildings. Lead can cause serious health problems, especially
    for
    pregnant women and young children. Please read this information
    closely to see
    what
    you
    can
    do to
    reduce lead in your drinking water.
    BOARD NOTE: The supplier must use the verbatim
    text set
    forth
    in this
    subsection
    (a) (1) (A),
    with the exception that
    the
    supplier must
    insert its name
    in place of the bracketed text.
    B)
    Health effects of lead. Lead can
    cause serious health problems if too
    much enters your
    body
    from drinking water or
    other sources. It can cause damage
    to the brain and
    kidneys, and can interfere
    with the production of red blood
    cells that carry
    oxygen
    to
    all parts
    of your body. The greatest risk of lead
    exposure is to
    infants, young children,
    and pregnant women. Scientists have
    linked
    the effects
    of lead on the brain with
    lowered IQ in children. Adults
    with kidney problems and high blood pressure
    can be
    affected
    by low levels of
    lead more than healthy adults. Lead is stored in the bones, and it
    can be
    released later in life. During pregnancy, the child receives lead from
    the
    mothers bones, which may affect brain development.
    BOARD NOTE: The supplier must use the verbatim text
    set
    forth in this
    subsection
    (a) (1) (B)

    ii)
    Explain possible sources of lead in drinking water and how lead enters
    drinking water. Include
    information
    on home and building plumbing materials and
    service lines that may contain
    lead.
    iii)
    Discuss other
    important
    sources of lead exposure in addition to drinking
    water (e.g.,
    paint).
    BOARD NOTE: The supplier must use text that provides the information
    described
    in
    this subsection
    (a) (1) (C)
    D)
    Discuss the steps the consumer can take
    to
    reduce his or her exposure
    to
    lead
    in drinking water.
    i)
    Encourage running the water to flush out the lead.
    ii)
    Explain concerns with using hot water from the tap and specifically
    caution against the use of hot water for preparing baby formula.
    iii)
    Explain that boiling
    water
    does not reduce lead levels.
    iv)
    Discuss other options consumers
    can take to reduce exposure to lead in
    drinking water, such
    as
    alternative sources or treatment of water.
    v)
    Suggest that parents have their child’s blood
    tested
    for lead.

    of this Section or must includc the text
    set
    forth
    in Appcndix F of this
    Part in all of thc printcd matcrials it distributes through
    its lead public
    education program. A water supplier may delete information
    pertaining to lead
    service lines
    upon approval
    by the Agency by
    a
    SEP issued
    pursuant to Section
    611.110 if no lead service lincs exist
    anlhcre
    in the water system
    service
    area. ry additional information presented
    by a supplier must
    be
    consistent
    with the information below and be in plain English that
    can be understood
    by lay
    persons.
    a CWS supplier must do both of the following:
    A)
    It must
    tell consumers
    how to get their water tested; and
    B)
    It must discuss lead in plumbing
    components and the difference between
    low-lead and lead-free components.
    3)
    Agency review and approval of written public
    education materials.
    A)
    The supplier must submit all written public
    education materials to the
    Agency for review at least 60 days prior
    to
    its planned
    date for delivery of the
    materials to the public.
    B)
    If the
    Agency
    determines that the form and content of the
    supplier’s
    written public education materials is adequate, it may
    4s-siaedis,siie
    a SEP
    pursuant to Section 611.110 that expressly approves of the materials.
    C)
    A supplier may immediately
    distribute its written public education
    materials after receipt of
    a
    SEP
    or a revised SEP that expressly approves
    those
    materials.
    D)
    If the Agency determines that
    the
    form or
    content of the written public
    education materials submitted by the supplier
    does not comply with the
    requirements of this Section, it must issue
    a
    SEP pursuant
    to Section 611.110.
    The
    Agency
    may issue a revised SEP that expressly supercedes
    a SEP previously
    issued
    under this
    subsection
    (a) (1).
    Any SEP or revised
    SEP issued by the
    Agency must
    identify any deficiencies in the written public
    education
    materials
    with specificity
    sufficient to guide the supplier
    to thed-r—-eer-r-ee-t4encnrractSha
    deficiencies
    in
    a
    way that would address the Agency’s concerns.
    E)
    The Agency must issue any SEP or revised SEP under subsection
    (a) (3) (D)
    of
    this Section no later
    than
    30 days after the date on which it received a copy of
    the supplier’s
    prospective written
    public education materials, unless the Agency
    and the supplier
    have agreed
    to a
    later
    date
    pursuant
    to subsection
    (a) (3) (F)
    of
    this Section. The
    Agency and the supplier may agree
    to a longer time within
    which
    the
    Agency may issue a SEP or
    a
    revised SEP, in which
    case the Agency must
    issue
    the
    SEP or revised SEP before expiration of the agreed longer time.
    BOARD NOTE: The
    Board has provided that the Agency and
    the supplier may agree
    to a longer time
    before the Agency issues
    a
    SEP and
    for the Agency to issue a
    revised SEP that
    supercedes an
    already-issued SEP, in order to allow for
    negotiation of any
    issues and
    the quickest possible distribution of the
    materials.
    F)
    If the
    supplier has not received
    a SEP
    from
    the Agency within 45 days
    after the date on
    which the Agency received
    its written public education
    materials
    to thc Agcncy, those materials are
    deemed approved, and the supplier
    may immediately
    proceed
    to
    distribute them.
    G)
    Once the
    supplier has revised its written public
    education
    materials
    exactly as
    described
    by
    the Agency in
    a
    SEP issued
    under subsection
    (a) (3) (U)
    of
    this Section,
    those materials are deemed approved, and the supplier may
    immediately proceed to distribute them.
    BOARD
    NOTE: At corresponding 40 CFR
    141.85(a) (1) (2007),
    USEPA allowed the
    State to
    require prior approval of written public information materials. Rather
    than require
    prior Agency approval, the Board has chosen
    to
    require submission
    to the
    Agency for review sufficiently in advance of distribution
    to
    allow
    the
    Agency to
    raise any deficiencies that it may perceive. The Board has
    used the
    mechanism of the SEP for the Agency
    to
    communicate its concerns,
    as
    this would
    allow the supplier to petition the Board for review of the Agency’s
    determination pursuant to Section
    611.110(c).

    water
    monitoring results.
    1)
    Consumer notice requirement. A supplier must
    provide a notice of the
    individual tap results from lead
    tap
    water monitoring
    carried out under the
    requirements of Section 611.356
    to
    the persons served
    by the water system at
    the
    specific sampling site from which the sample was taken
    (e.g., the occupants of
    the
    residence where the tap was
    tested)
    2)
    Timing of consumer notice.
    The supplier must provide the consumer
    notice
    as
    soon
    as
    practical,
    but
    no later
    than 30 days after it learns of the
    tap
    monitoring results.
    3)
    Content
    of consumer
    notice. The consumer notice must
    include the results
    of lead tap
    water monitoring
    for the tap that was tested,
    an
    explanation
    of the
    health
    effects of lead, list
    steps consumers can take
    to
    reduce exposure
    to lead

    to Section 611.110, a
    ‘c) (2) (B)
    in drinking
    water, and
    contact information
    for
    the
    water
    utility. The notice
    must also
    provide the maximum
    contaminant
    level
    goal
    and the
    action level
    for
    lead
    and
    the
    definitions for
    these two terms
    from
    Section
    611.883(c).
    4)
    Delivery
    of consumer
    notice.
    The consumer notice
    must be provided
    to
    persons
    served at
    the
    tap that was tested,
    either
    by
    mail
    or by another method
    approved
    by
    the
    Agency,
    by
    a SEP issued pursuant
    to
    Section
    611.110. For
    example, upon
    approval
    by the
    Agency, a NTNCWS
    supplier could post
    the results
    on a bulletin
    board in

    a)
    Sample
    Sampling site
    location.
    1)
    Selecting
    a
    pool of targeted
    sampling
    sites.
    A)
    By the
    applicable
    date for
    commencement of
    monitoring under subsection
    (d) (1)
    of
    this Section, each
    supplier
    must complete
    a
    materials
    evaluation
    of
    its
    distribution
    system in order
    to identify
    a pool of
    targeted
    sampling
    sites
    that meets
    the
    requirements of this
    Section.
    B)
    The
    pooi of targeted
    sampling sites
    must be
    sufficiently
    large
    to ensure
    that
    the
    supplier can collect
    the number
    of lead and
    copper
    tap
    samples
    required
    by
    subsection
    (c)
    of this Section.
    C)
    The supplier
    must select the
    sites for collection
    of first draw
    samples
    from
    this
    pool of targeted
    sampling sites.
    D)
    The supplier
    must not select
    as sampling
    sites
    any faucets
    that have
    point-of-use or
    point-of-entry treatment
    devices

    on lead,
    copper, and galvanized
    steel
    collected
    pursuant
    to
    40
    CFR
    141.42(d)
    (special monitoring
    for corrosivity
    characteristics)
    when conducting
    a materials
    evaluation.
    B)
    When an
    evaluation
    of the information
    collected
    pursuant
    to

    141.42(d)
    is
    insufficient
    to locate the
    requisite number
    of lead and
    copper
    sampling
    sites
    that meet
    the targeting criteria
    in subsection
    (a)
    of this
    Section, the
    supplier
    must review
    the following
    sources of information
    in
    order
    to
    identify a
    sufficient
    number
    of sampling sites:
    i)
    All
    plumbing
    codes,
    permits, and
    records in
    the
    files
    of the building
    departments
    that
    indicate
    the plumbing materials
    that
    are installed
    within
    publicly-
    and privately-owned
    structures connected
    to
    the distribution
    system;
    ii)
    All inspections and records of the
    distribution system that
    indicate the
    material composition of the service connections
    which connect
    a structure to the
    distribution system;
    iii) All existing water
    quality
    information,
    which includes the results
    of all
    prior analyses of the
    system or
    individual
    structures connected
    to the system,
    indicating locations that may
    be
    particularly
    susceptible
    to
    high lead
    or copper
    concentrations; and
    iv)
    The supplier
    must
    seek to collect such information
    where possible in the
    course of its
    normal operations
    (e.g., checking service
    line materials when
    reading
    water meters or
    performing maintenance activities)
    3)
    Tiers of sampling sites. Suppliers
    must categorize the sampling sites
    within their pool according
    to
    the following
    tiers:
    A)
    CWS Tier 1 sampling sites.
    “CWS Tier
    1 sampling sites’ must include the
    following single-family structures:

    of
    first-draw
    samples may
    be done up
    to
    14
    days
    after the
    sample is
    collected.
    ii)
    After
    acidification
    to resolubilize
    the
    metals,
    the
    sample must
    stand in
    the original
    container
    for
    the time specified
    in the
    approved
    USEPA
    method
    before the
    sample
    can
    be analyzed.
    F)
    If
    a
    supplier
    allows
    residents
    to
    perform sampling
    under
    subsection
    (b)
    (2)
    (D)
    of
    this
    Section,
    the supplier
    may
    not
    challenge

    after flushing
    that volume
    of water calculated
    as being
    between
    the tap and
    the lead
    service line
    based on the
    interior diameter
    and length
    of
    the pipe
    between the
    tap
    and
    the
    lead service line;
    ii)
    Tapping
    directly into
    the lead
    service
    line; or
    iii)
    If the
    sampling
    site is a single-family
    structure,
    allowing
    the
    water
    to
    run until
    there is a
    significant change
    in temperature that
    would
    be
    indicative
    of
    water
    that has been standing
    in the lead
    service
    line.
    4)
    Follow-up
    first-draw
    tap samples.
    A)
    A supplier
    must
    collect each follow-up
    first-draw
    tap sample from
    the same
    sampling
    site from which
    it collected the
    previous samples.
    B)
    If, for
    any
    reason, the supplier
    cannot
    gain
    entry
    to
    a
    sampling
    site in
    order
    to
    collect a
    follow-up tap sample,
    the
    supplier
    may collect the
    follow-up
    tap
    sample
    from another
    sampling site in
    its
    sampling
    pool,
    as
    long
    as the new
    site
    meets
    the
    same
    targeting
    criteria and
    is
    within
    reasonable
    proximity
    of the
    original site.
    5)
    Substitute
    non-first-draw
    samples.
    A)
    A
    NTNCWS
    supplier or a CWS
    supplier
    that meets
    the
    criteria
    of Sections
    61l.355(eb)
    (7) (A)
    and
    (eb) (7) (B),
    that
    does not
    have
    enough
    taps
    that can
    supply
    first-draw
    samples, as
    defined in
    Section 611.102,
    may
    apply
    to the
    Agency in
    writing
    to
    substitute non-first-draw
    samples
    by a SEP
    granted
    under
    Section
    611
    .110.
    B)
    A
    supplier approved to substitute non-first-draw
    samples must collect
    as
    many first-draw samples
    from appropriate
    taps
    as
    possible
    and identify sampling
    times and locations that
    would likely
    result in the longest
    standing time for
    the remaining sites.
    C)
    The Agency may grant a
    SEP
    that waives the requirement for
    prior Agency
    approval
    of non-first-draw zamplc sampling sites selected
    by
    the
    system.
    c)
    Number of samples.
    1)
    Suppliers must collect at least one sample from the number
    of sites listed
    in the first column of Table 3D of this Part (labelled
    “standard monitoring”)
    during each six-month monitoring period
    specified in subsection
    (d)
    of this
    Section.
    2)
    A supplier conducting reduced monitoring
    pursuant to subsection
    (d) (4)
    of
    this Section must collect one sample from the
    number of sites specified in the
    second column of Table 3D of this Part
    (labelled
    “reduced
    monitoring”)
    during
    each reduced monitoring period specified in subsection
    (d)
    (4) of
    this Section.
    Such reduced monitoring sites must be representative of the sites
    required for
    standard monitoring. A supplier whose system has fewer than five
    drinking water
    taps that can be used for human consumption and which can meet the
    sampling site
    criteria of subsection
    (a)
    of this Section
    to
    reach the required number
    of
    sampling
    sites
    listed in this
    subsection
    7
    (c)-
    must collect multiple samples
    from
    individual taps.
    To accomplish this,
    the supplier must collect at least
    one
    sample
    from each
    tap,
    then it must collect
    additional samples from those same
    taps on
    different
    days
    during the monitoring
    period, in order to collect
    a total
    number of
    samples that meets the required
    number of sampling sites.
    Alternatively, the Agency must,
    by a
    SEP
    issued pursuant to Section 611.110,
    allow
    a
    supplier whose system has fewer
    than five drinking water taps to collect
    a
    number
    of
    samples that is fewer than
    the number of sites specified in this
    subsection
    (c)
    of thic Section if it
    determines that 100 percent of all taps
    that can be used
    for human consumption
    are sampled and that the reduced number
    of samples
    will produce the
    same
    results
    as would the collection of multiple
    samples from
    some
    taps. Any Agency approval of a reduction of the minimum
    number of
    samples must
    be based on a request from the supplier or on on-site
    verification
    by
    the Agency. The
    Agency may, by a SEP issued pursuant to
    Section
    611.110, specify sampling locations when
    a system is conducting reduced
    monitoring.
    d)
    Timing of monitoring.
    1)
    Initial tap sampling.
    The first
    six-month
    monitoring period for small, medium-sized and large
    system
    suppliers must
    begin on the dates specified in Table E of this Part.
    A)
    All large system suppliers
    must monitor during each of two consecutive
    six-month periods.
    B)
    All small- and medium-sized
    system
    suppliers
    must monitor during each
    consecutive six-month monitoring
    period
    until
    the
    following
    is true:
    i)
    The supplier exceeds the lead action level or
    the copper action level and
    is therefore required to implement the corrosion control treatment requirements
    under Section
    611.351,
    in which case the supplier must continue monitoring
    in
    accordance
    with
    subsection
    (d) (2)
    of this Section; or
    ii)
    The supplier
    meets
    the lead
    action level and
    the copper action
    level
    during each
    of two consecutive
    six-month
    monitoring periods,
    in which
    case the
    supplier
    may
    reduce monitoring
    in
    accordance
    with subsection
    (d) (4)
    of this
    Section.
    2)
    Monitoring after
    installation

    monitoring
    periods before
    January 1, 1998.
    B)
    Any
    small-
    or medium-sized
    system
    supplier that
    installs
    optimal corrosion
    control
    treatment
    pursuant
    to
    Section
    611.351(e)
    (5)
    must monitor
    during each
    of
    two
    consecutive six-month
    monitoring
    periods before
    36
    months
    after
    the Agency
    approves
    optimal corrosion
    control
    treatment, as
    specified in Section
    611.351
    Ce)
    (6).
    C)
    Any
    supplier
    that installs
    source water treatment
    pursuant
    to Section
    611.353
    (a) (3)
    must monitor
    during each
    of two consecutive
    six-month monitoring
    periods
    before 36
    months after
    completion
    of
    step
    2,
    as
    specified in
    Section
    611.353
    (a)
    (4).
    3)
    Monitoring
    after
    the
    Agency
    specification
    of
    water quality parameter
    values
    for
    optimal corrosion
    control.
    After
    the Agency
    specifies the
    values for
    water quality
    control parameters
    pursuant
    to
    Section
    611.352(f),
    the supplier
    must monitor during
    each
    subsequent
    six-month
    monitoring
    period, with
    the first six-month
    monitoring
    period
    to
    begin
    on the
    date
    the Agency
    specifies
    the optimal values.
    4)
    Reduced
    monitoring.
    A)
    Reduction to
    annual for small-
    and medium-sized
    system suppliers
    meeting
    the lead and
    copper action
    levels.
    A small- or medium-sized
    system
    supplier
    that
    meets
    the lead and copper
    action levels
    during each
    of
    two consecutive
    six-
    month
    monitoring
    periods may
    reduce
    the
    number of
    samples
    in accordance with
    subsection
    Cc)
    of this Section,
    and
    reduce
    the frequency
    of
    sampling to once
    per
    year. A
    small- or
    medium-sized system
    supplier
    that
    collects fewer
    than five
    samples as
    specified
    in subsection
    Cc)
    of this Section and
    which meets
    the lead
    and
    copper
    action
    levels
    during each of two
    consecutive six-month
    monitoring
    periods
    may
    reduce
    its
    frequency
    of sampling
    to once
    per year.
    In
    no case
    can
    the
    supplier
    reduce the
    number of
    samples required
    below the minimum
    of one
    sample
    per
    available
    tap.
    This
    reduced
    sampling may
    only begin during
    the
    calendar
    year
    immediately following
    the
    end of the second
    consecutive six-month
    monitoring
    period.
    B)
    SEP

    action
    level and
    which
    maintains the
    range
    of values
    for
    the water quality
    control parameters
    reflecting
    optimal
    corrosion
    control
    treatment
    specified
    by
    the Agency under
    Section 611.352(f)
    during each
    of
    two consecutive
    six-month monitoring
    periods
    may reduce the
    frequency of
    monitoring
    to
    once
    per year and the
    number of lead
    and copper
    samples to
    that specified
    by subsection
    Cc)
    of this
    Section if it receives
    written
    approval from the
    Agency
    in
    the form of
    a
    SEP
    granted pursuant
    to
    Section 611.110.
    This reduced
    sampling may only
    begin
    during the
    calendar
    year
    immediately
    following
    the
    end of
    the second consecutive
    six-month
    monitoring
    period.
    ii)
    The
    Agency must
    review
    monitoring, treatment,
    and
    other
    relevant
    information
    submitted
    by the
    water system in accordance
    with Section
    611.360,
    and must notify
    the system
    in writing
    by
    a
    SEP granted
    pursuant
    to Sections
    611.110 when
    it determines
    the system
    is eligible
    to
    reduce its monitoring
    frequency
    to
    once every three
    years pursuant
    to this
    subsection
    (d) (4)
    iii)
    The
    Agency must
    review,
    and where appropriate,
    revise its
    determination
    under
    subsection
    (d) (4) (B)
    (i)
    of this
    Section when
    the supplier submits
    new
    monitoring
    or treatment data,
    or when
    other data relevant
    to the number
    and
    frequency
    of
    tap sampling becomes
    available
    to the
    Agency.
    C)

    triennial for small-
    and medium-sized
    system
    suppliers.
    i)
    Small-
    and medium-sized
    system
    suppliers meeting
    lead
    and copper
    action
    levels.
    A
    small- or medium-sized
    system
    supplier that
    meets
    the lead action
    level
    and
    which
    meets the lead and
    copper
    action levels
    during
    three consecutive
    years of
    monitoring
    may reduce the
    frequency
    of
    monitoring
    for
    lead and copper
    from
    annually
    to once
    every three years.
    ii)
    SEP
    for
    suppliers meeting
    optimal
    corrosion
    control
    treatment. Any
    supplier
    that maintains
    the range
    of values
    for the
    water
    quality
    control
    parameters
    reflecting
    optimal corrosion
    control
    treatment
    specified
    by the
    Agency
    under
    Section
    611.352(f)
    during
    three consecutive
    years of
    monitoring
    may
    reduce
    its
    monitoring frequency
    from annual
    to once
    every three
    years
    if it
    receives written
    approval from
    the Agency in
    the form
    of
    a
    SEP
    granted
    pursuant
    to
    Section
    611.110.
    Samples collected
    once every
    three years must
    be collected
    no
    later than
    every
    third calendar
    year.
    iii)
    The
    Agency
    must
    review,
    and where appropriate,
    revise
    its determination
    under subsection
    (d) (4) (C) (ii)
    of this Section
    when
    the supplier
    submits
    new
    monitoring or
    treatment
    data, or
    when other
    data
    relevant to the number
    and
    frequency
    of tap
    sampling
    becomes
    available
    to the Agency.
    D)
    Sampling
    at a reduced frequency.
    A
    supplier that
    reduces
    the number and
    frequency of
    sampling
    must collect
    these samples
    from
    representative
    sites
    included in
    the pool
    of targeted
    sampling sites identified
    in subsection
    (a)
    of
    this
    Section,
    preferentially
    selecting
    those sampling
    sites
    from the highest
    tier
    first.
    Suppliers sampling
    annually
    or less frequently
    must conduct
    the
    lead and
    copper
    tap sampling during
    the months
    of June,
    July,
    August, or
    September,
    unless
    the Agency has approved
    a different
    sampling
    period in
    accordance
    with subsection
    (d) (4) (D) (i)
    of
    this
    Section.
    i)
    The
    Agency
    may grant
    a
    SEP pursuant
    to Section
    611.110 that
    approves
    a
    different
    period
    for conducting
    the lead
    and
    copper tap
    sampling
    for systems
    collecting
    a
    reduced
    number of samples.
    Such
    a period
    must
    be
    no
    longer than
    four
    consecutive months
    and must represent
    a time
    of
    normal
    operation
    where the
    highest
    levels of lead are
    most likely
    to occur. For
    a NTNCWS
    supplier
    that
    does
    not
    operate
    during
    the
    months of June through
    September and
    for which
    the
    period of normal
    operation
    where
    the highest levels
    of lead are most
    likely
    to
    occur
    is not
    known, the Agency
    must
    designate
    a
    period
    that represents
    a time of
    normal
    operation
    for the system.
    This
    reduced sampling
    may only begin during
    the
    period
    approved
    or designated
    by the Agency
    in the calendar
    year immediately
    following
    the end
    of the second consecutive
    six-month
    monitoring period
    for
    systems
    initiating
    annual monitoring
    and
    during
    the
    three-year
    period following
    the end of
    the third
    consecutive calendar
    year
    of
    annual
    monitoring
    for a
    supplier
    initiating
    triennial
    monitoring.
    ii)

    monitoring
    annually
    that has
    been collecting samples
    during
    the
    months of June
    through
    September and which
    receives
    Agency approval
    to alter its
    sample collection
    period
    under subsection
    Cd) (4) (D) (i)
    of this Section
    must
    collect
    its
    next round
    of samples during
    a time period that
    ends no later
    than
    21 months
    after
    the previous
    round of sampling.
    A supplier
    monitoring once
    every
    three
    years
    that
    has been
    collecting samples
    during the months
    of June
    through September
    and
    which receives
    Agency approval
    to alter the
    sampling
    collection
    period
    as
    provided
    in subsection
    (d) (4)
    (D)
    (i)
    of this Section
    must
    collect
    its
    next round
    of samples during
    a time period that
    ends no later
    than
    45
    months
    after
    the previous
    round of sampling.
    Subsequent
    rounds of sampling
    must
    be
    collected
    annually
    or
    once every three
    years,
    as required
    by this
    Section. A
    small
    system supplier
    with a waiver granted
    pursuant to
    subsection
    (g) of
    this
    Section that
    has been collecting
    samples
    during the months
    of
    June
    through
    September
    and which
    receives Agency
    approval to
    alter its sample
    collection
    period
    under
    subsection
    Cd) (4) CD) (i)
    of
    this Section
    must collect
    its
    next round
    of samples
    before the
    end of the nine-year
    compliance
    cycle
    (as
    that
    term is defined
    in Section
    611.101)
    E)
    Any water
    system that demonstrates
    for two consecutive
    six-month
    monitoring
    periods
    that the
    tap
    water
    lead

    quality parameters
    within the
    distribution
    system
    under
    the
    following conditions:
    i)
    The supplier
    may resume
    annual
    monitoring for lead
    and copper at
    the
    tap
    at
    the
    reduced
    number of
    sites specified
    in subsection
    (c)
    of this Section
    after
    it has completed
    two subsequent
    six-month
    rounds of
    monitoring
    that meet the
    criteria of
    subsection
    (d) (4) (B)
    of this Section
    and
    the supplier has
    received
    written
    approval from
    the Agency
    by a
    SEP
    pursuant
    to
    Section
    611.110
    that it is
    appropriate
    to resume reduced
    monitoring
    on an annual
    frequency.
    This
    sampling
    must
    begin
    during the calendar
    year immediately
    following the end
    of the
    second
    consecutive
    six-month
    monitoring
    period.
    ii)
    The
    supplier may
    resume monitoring
    for lead
    and
    copper
    once
    every
    three
    years
    at the
    tap at the reduced
    number
    of sites after
    it demonstrates
    through
    subsequent
    rounds of monitoring
    that
    it
    meets the
    criteria of either
    subsection
    (d) (4) (C)
    or
    (d) (4)
    (E)
    of this
    Section and
    the system
    has received
    a
    SEP
    under
    Section
    611.110 from
    the Agency that
    it is
    appropriate
    to resume monitoring
    once
    every three
    years.
    iii)
    The supplier
    may reduce
    the number of water
    quality parameter
    tap water
    samples
    required in accordance
    with
    Section

    e)
    Additional
    monitoring.
    The results
    of
    any
    monitoring
    conducted in
    addition
    to
    the
    minimum
    requirements
    of this
    Section
    must be
    considered
    by the
    supplier and
    the
    Agency
    in making
    any determinations
    (i.e.,
    calculating
    the
    90th
    percentile lead
    action
    level or
    the copper level)
    under this Subpart
    G.
    f)
    Invalidation
    of lead
    or copper tap
    water
    samples.
    A sample invalidated
    under this
    subsection
    does
    not count toward
    determining lead
    or copper 90th
    percentile
    levels
    under
    Section
    611.350(c) (3)
    or toward meeting
    the minimum
    monitoring
    requirements
    of subsection
    (c)
    of this
    Section.
    1)
    The Agency
    must invalidate
    a lead
    or copper
    tap
    water
    sample if it
    determines
    that
    one of the following
    conditions
    exists:
    A)
    The laboratory
    establishes
    that improper sample
    analysis caused
    erroneous
    results;
    B)
    The
    sample
    was taken from
    a site that
    did not meet the
    site selection
    criteria of
    this Section;
    C)
    The
    sample container
    was damaged
    in transit; or
    D)
    There
    is
    substantial reason
    to
    believe
    that the
    sample was
    subject to
    tampering.
    2)
    The
    supplier must report
    the results
    of all
    samples to
    the Agency
    and all
    supporting
    documentation for
    samples the
    supplier
    believes should
    be
    invalidated.
    3)
    To
    invalidate a
    sample under subsection
    (f) (1)
    of
    this Section, the
    decision
    and the
    rationale
    for the decision
    must
    be
    documented
    in writing.
    The
    Agency
    may
    not
    invalidate
    a
    sample solely on the
    grounds that a
    follow-up
    sample
    result is
    higher or lower
    than that
    of the original
    sample.
    4)
    The water
    supplier must
    collect replacement
    samples
    for any samples
    invalidated
    under
    this Section if,
    after the
    invalidation
    of one or
    more
    samples, the
    supplier
    has too few samples
    to meet
    the
    minimum requirements
    of
    subsection
    (c)
    of this
    Section. Any such
    replacement samples
    must
    be
    taken
    as
    soon
    as
    possible, but no
    later than 20
    days after the
    date the
    Agency
    invalidates
    the sample or by
    the end of the applicable
    monitoring
    period,
    whichever
    occurs
    later. Replacement
    samples
    taken
    after the end of
    the
    applicable
    monitoring
    period must not
    also
    be
    used to
    meet the monitoring
    requirements
    of
    a subsequent
    monitoring
    period. The replacement
    samples must
    be
    taken
    at
    the
    same
    locations
    as the invalidated
    samples or, if
    that is not
    possible,
    at
    locations
    other
    than those already
    used
    for sampling
    during the
    monitoring
    period.
    g)
    Monitoring
    waivers for
    small
    system
    suppliers.
    Any
    small system supplier
    that
    meets
    the
    criteria of this
    subsection
    (g) may apply to
    the Agency to reduce
    the
    frequency
    of monitoring
    for
    lead and copper
    under this Section
    to once every
    nine
    years
    (i.e.,
    a “full
    waiver”)
    if it meets all
    of
    the
    materials
    criteria
    specified
    in
    subsection (g)
    (1)
    of
    this
    Section and all
    of
    the monitoring
    criteria specified in subsection (g)
    (2)
    of this Section.
    Any small system
    supplier that meets the criteria in subsections
    (g)
    (1)
    and (g)
    (2)
    of this
    Section only for lead, or only for copper, may
    apply to the State for a waiver
    to reduce the frequency of tap water monitoring
    to
    once
    every nine years for
    that contaminant only
    (i.e.,
    a ‘partial
    waiver”).
    1)
    Materials
    criteria.
    The supplier must demonstrate that its distribution
    system and service
    lines and
    all drinking water supply plumbing, including
    plumbing conveying
    drinking water
    within all residences and buildings connected
    to the system, are
    free
    of lead-containing materials or copper-containing
    materials, as those
    terms
    are defined in this subsection
    (g)
    (1),
    as
    follows:
    A)
    Lead. To
    qualify
    for a full waiver, or a waiver of the
    tap
    water
    monitoring requirements for lead
    (i.e.,
    a “lead
    waiver”),
    the water supplier
    must provide
    certification
    and supporting documentation
    to
    the Agency that
    the
    system is free of all
    lead-containing
    materials, as follows:
    i)
    It contains no
    plastic
    pipes that contain lead plasticizers, or plastic
    service lines that
    contain
    lead plasticizers; and
    ii)
    It is free
    of lead service
    lines, lead pipes, lead soldered pipe joints,
    and leaded brass
    or bronze alloy
    fittings and fixtures, unless such fittings
    and
    fixtures meet
    the specifications
    of NSF Standard 61, section
    9,
    incorporated
    by
    reference in
    Section 611.102.
    BOARD
    NOTE:
    Corresponding
    40 CFR 141.86(g)
    (1) (i) (B)
    specifies “any
    standard
    established pursuant
    to 42 USC 300g-6(e)
    (SDWA
    section
    1417(e))
    USEPA has stated
    that the NSF
    standard is that standard.
    See
    62 Fed. Reg.
    44684
    (Aug. 22,
    1997)
    B)
    Copper.
    To qualify for
    a
    full
    waiver, or a waiver of the tap water
    monitoring requirements for copper
    (i.e.,
    a “copper
    waiver”),
    the water supplier
    must provide certification and supporting documentation
    to the Agency that the
    system contains no copper pipes or copper service lines.
    2)
    Monitoring criteria for waiver issuance. The supplier must have completed
    at least one six-month round of standard tap water monitoring for lead and
    copper at sites
    approved
    by
    the
    Agency and from the number of sites required
    by
    subsection
    (c)
    of this Section and
    demonstrate that the 90th percentile levels
    for any and all rounds of monitoring
    conducted since the system became free
    of
    all
    lead-containing or copper-containing
    materials, as appropriate, meet the
    following
    criteria:
    A)
    Lead levels.
    To qualify
    for a full waiver, or a lead waiver, the
    supplier
    must demonstrate that the 90th percentile lead level does not exceed
    0.005 mg/l.
    B)
    Copper
    levels.
    To qualify for a full waiver, or
    a
    copper waiver, the
    supplier must
    demonstrate that
    the 90th percentile copper level
    does
    not exceed
    0.65 mg/l.
    3)
    State
    approval of waiver application.
    The Agency must notify the supplier
    of its waiver determination by
    a
    SEP
    issued pursuant to Section 611.110, in
    writing, setting forth the basis of its decision and
    any condition of the
    waiver. As a
    condition
    of the waiver, the Agency may require the supplier
    to
    perform specific activities
    (e.g., limited monitoring, periodic outreach
    to
    customers
    to
    remind them
    to
    avoid installation
    of materials that might void
    the
    waiver)
    to avoid the risk of lead
    or
    copper
    concentration of concern in tap
    water.
    The
    small system supplier must
    continue monitoring
    for lead and copper
    at
    the
    tap as
    required
    by
    subsections
    Cd) (1)
    through

    of this Section,
    as
    appropriate,
    until it
    receives written
    notification
    from the Agency that the
    waiver
    has been
    approved.
    4)
    Monitoring frequency for suppliers
    with waivers.
    A)
    A supplier with
    a
    full waiver must
    conduct
    tap
    water monitoring
    for lead
    and copper in accordance with subsection
    (d) (4) CD)
    of this
    Section at the
    reduced number of sampling sites identified
    in subsection
    (c)
    of this Section
    at
    least once every nine years and provide
    the materials certification
    specified in
    subsection (g)
    (1)
    of this Section for
    both lead and copper
    to
    the
    Agency along
    with the monitoring results. Samples
    collected every nine
    years must be
    collected no later than every ninth
    calendar year.
    B)
    A supplier with
    a
    partial waiver
    must conduct
    tap
    water
    monitoring for the
    waived contaminant in accordance with
    subsection
    Cd) (4) (D)
    of this
    Section at

    provide the materials certification
    specified
    in subsection (g)
    (1)
    of this
    Section pertaining
    to
    the waived
    contaminant along
    with the monitoring results.
    Such a supplier also must continue
    to monitor for
    the non-waived contaminant in accordance
    with requirements of
    subsections
    Cd) Cl)
    through
    (d) (4)
    of this Section,
    as
    appropriate.
    C)
    If a Any supplier with a full or partial
    waiver adds a now oourcc
    of watcr
    or changcz any watcr trcatmcnt, thc cupplicr
    must notify the Agency in writing
    in accordance with Section
    611.360(a) (3)
    of
    any upcoming long-term change
    in
    treatment
    or addition of a new source,
    as described in that zcctionSection.
    The
    Agency must
    review
    and approve the addition of
    a
    new
    source or long-term change
    in water treatment before it is implemented
    by the supplier. The Agency has
    the
    authority to require the supplier to add or modify waiver
    conditions (e.g.,
    require recertification that the supplier’s system is free
    of lead-containing
    or
    copper-containing materials, require additional rounds
    of monitoring), if it
    deems such
    modifications
    are necessary to address treatment
    or source water
    changes at
    the
    system.
    D)
    If
    a
    supplier with
    a
    full
    or partial waiver becomes aware
    that it is no
    longer free of lead-containing
    or copper-containing materials,
    as appropriate
    (e.g., as a
    result of new construction
    or repairs), the supplier must
    notify the
    Agency in writing no later
    than 60 days after becoming aware of
    such a change.
    5)
    Continued eligibility. If
    the supplier continues
    to
    satisfy the
    requirements of subsection
    (g)
    (4)
    of this Section, the waiver will
    be renewed
    automatically, unless any of the
    conditions listed in subsection
    (g)
    (5)
    (A)
    through (g)
    (5) (C)
    of this Section
    occur.
    A
    supplier whose waiver has
    been
    revoked may re-apply for a waiver
    at
    such time
    as
    it
    again meets the appropriate
    materials and monitoring
    criteria of subsections (g)
    (1)
    and
    (g)
    (2)
    of this
    Section.
    A)
    A supplier with
    a
    full waiver
    or a lead waiver no longer
    satisfies the
    materials criteria of subsection

    the waiver has been
    revoked, setting
    forth
    the basis of its decision.
    6)
    Requirements
    following
    waiver revocation. A
    supplier whose full or
    partial waiver has
    been revoked
    by the Agency is

    effective
    Section 611.357
    Monitoring for Water Quality Parameters
    All large system suppliers, and all small- and medium-sized
    system suppliers
    that exceed the lead action level or the copper
    action level, must monitor water
    quality
    parameters in
    addition to lead and copper in
    accordance with this
    Section.
    The requirements
    of this Section are summarized
    in Table G of this
    Part.
    a)
    General Requirements.
    1)
    Sample
    collection
    methods.
    A)
    Use of tap
    samples.
    The totality of all
    tap
    samples
    collected by a
    supplier must be
    representative
    of water quality throughout the distribution
    system
    taking
    into account
    the number of persons served, the different
    sources
    of water,
    the
    different treatment methods
    employed by the supplier, and
    seasonal
    variability. Although a supplier may conveniently
    conduct tap sampling for
    water quality parameters at sites
    used
    for coliform
    sampling performed pursuant
    to Subpart L of this Part, it is not required
    to do so, and a supplier is not
    required
    to
    perform tap sampling pursuant
    to this Section at taps targeted for
    lead and copper sampling under Section
    611.356(a)
    B)
    Use
    of entry point samples. Each
    supplier must collect samples at entry
    points
    to
    the distribution system from
    locations representative of each source
    after treatment. If a supplier draws
    water from more than one source and the
    sources are combined before distribution,
    the supplier must sample
    at
    an
    entry
    point
    to
    the distribution system during
    periods of normal operating conditions
    (i.e.,
    when water is representative
    of all sources being
    used).
    2)
    Number of samples.
    A)
    Tap samples. Each supplier must collect two
    tap samples for applicable
    water quality parameters during each six-month
    monitoring period specified under
    subsections
    (b)
    through
    (e)
    of this Section from
    the number of sites indicated
    in the first column of Table E of this Part.
    B)
    Entry point samples.
    i)
    Initial
    monitoring.
    Except as provided in subsection
    (c) (3)
    of this
    Section,
    each supplier must
    collect two samples for each applicable water
    quality parameter
    at
    each entry
    point to the distribution system during
    each
    six-month monitoring period
    specified in subsection
    (b)
    of this Section.
    ii)
    Subsequent monitoring. Each
    supplier must collect one sample for
    each
    applicable water quality parameter
    at each entry point to the distribution
    system during each six-month monitoring period
    specified in subsections
    (c)
    through
    (e)
    of this Section.
    b)
    Initial Sampling.
    1)
    Large systems. Each large
    system supplier must measure the applicable
    water quality parameters specified in
    subsection
    (b) (3)
    of this Section
    at taps
    and at
    each entry point
    to
    the distribution
    system during each six-month
    monitoring period specified in Section
    611.356(d) (1).
    2)
    Small- and medium-sized systems. Each small-
    and medium-sized system
    supplier must measure the applicable water quality
    parameters specified in
    subsection
    (b) (3)
    of this Section at the locations specified
    in this subsection
    during each six-month monitoring period specified in Section
    611.356(d) (1)
    during
    which the
    supplier exceeds the lead action level or
    the copper action
    level.
    3)
    Water quality parameters.
    A)
    pH;
    B)
    Alkalinity;
    C)
    Orthophosphate, when an inhibitor
    containing a phosphate compound
    is used;
    D)
    Silica, when an inhibitor containing
    a silicate compound is

    Large systems. Each large system
    supplier that installs optimal corrosion
    control treatment pursuant to Section
    611.351(d) (4)
    must measure the
    water
    quality parameters at the locations and
    frequencies specified in
    subsections
    (c) (4)
    and
    (c) (5)
    of this Section during
    each six-month monitoring period
    specified in Section
    611.356(d) (2) (A).
    2)
    Small- and medium-sized systems. Each small-
    or medium-sized system that
    installs
    optimal corrosion control
    treatment pursuant
    to
    Section
    611.351(e) (5)
    must
    measure the water quality
    parameters at the locations and
    frequencies
    specified in subsections

    of this Section during
    each six-month
    monitoring period specified in
    Section
    611.356(d) (2) (B)
    in which
    the supplier
    exceeds the
    lead action level
    or the copper action level.
    3)
    Any groundwater system can limit
    entry point sampling described in
    subsection
    (c) (2)
    of this Section
    to those entry points that are
    representative
    of water quality and treatment conditions
    throughout the system. If water
    from
    untreated groundwater sources mixes
    with water from treated groundwater
    sources,
    the system must monitor for water
    quality parameters both
    at
    representative
    entry points receiving treatment
    and representative entry points
    receiving no
    treatment. Prior
    to
    the
    start of any monitoring under this
    subsection, the
    system must
    provide
    to the Agency written information identifying
    the selected
    entry
    points and
    documentation,
    including information on
    seasonal variability,
    sufficient
    to
    demonstrate that
    the sites are representative of water
    quality and
    treatment conditions throughout
    the system.
    4)
    Tap water samples, two samples
    at each tap for each of the following
    water
    quality parameters:
    A)

    D)
    Silica, when an inhibitor
    containing a silicate compound is
    used; and
    E)
    Calcium, when calcium
    carbonate stabilization is used
    as
    part of
    corrosion
    control.
    5)
    Entry point samples, except
    as provided in subsection
    (c) (3)
    of this
    Section, one sample at each
    entry point to the distribution system every
    two
    weeks (bi-weekly) for each of the
    following
    water
    quality parameters:
    A)
    pH;
    B)
    When alkalinity is adjusted
    as part of optimal corrosion control,
    a
    reading of the
    dosage
    rate of the
    chemical used to adjust alkalinity, and the
    alkalinity concentration; and
    C)
    When
    a
    corrosion inhibitor is
    used as part of optimal corrosion control,

    requirements
    regarding
    sample
    location, number
    of samples,
    and
    collection
    methods:
    A)
    A groundwater
    supplier
    must take
    a
    minimum
    of one sample
    at
    every entry
    point
    to
    the distribution
    system that is
    representative
    of each well
    after
    treatment
    (hereafter
    called

    BOARD
    NOTE: For
    the
    purposes
    of this
    subsection
    (a) (1)
    (B),
    surface
    water
    systems include
    systems
    with a combination
    of surface and ground
    sources.
    C)
    If
    a
    supplier draws
    water from more
    than one
    source and the sources
    are
    combined
    before distribution,
    the
    supplier
    must sample
    at an entry
    point
    to the
    distribution
    system during
    periods
    of normal operating
    conditions
    (i.e., when
    water is representative
    of
    all sources
    being
    used)
    D)
    The Agency
    may,
    by a
    SEP
    issued pursuant
    to Section
    611.110, reduce
    the
    total number of
    samples that
    must
    be analyzed
    by allowing the
    use
    of
    compositing.
    Compositing
    of
    samples
    must
    be done
    by certified
    laboratory
    personnel.
    Composite
    samples from a maximum
    of five
    samples are allowed,
    provided
    that if the
    lead
    concentration in
    the
    composite
    sample is greater
    than
    or
    equal
    to 0.001
    mg/l
    or
    the
    copper concentration
    is greater
    than or equal
    to
    0.160
    mg/l, then
    the supplier must
    do either of
    the following:
    i)
    The supplier must
    take and analyze
    a follow-up
    sample within
    14 days at
    each sampling
    point included
    in
    the composite;
    or
    ii)
    If duplicates
    of or sufficient
    quantities from
    the original
    samples
    from
    each
    sampling point
    used in
    the
    composite
    are available,
    the supplier
    may
    use
    these
    instead
    of resampling.
    2)
    SEP requiring
    an
    additional
    sample.
    e
    A)
    When
    the Agency
    determines
    that the results
    of sampling
    indicate an
    exceedence
    of the lead or
    copper MPC
    established
    under Section
    611.353(b)
    (4),
    it
    must, by
    a
    SEP
    issued
    pursuant to Section
    611.110,
    require the supplier
    to
    collect
    one additional
    sample
    as soon
    as possible after
    the initial sample
    at
    the
    same sampling point,
    but
    no later than
    two weeks after
    the supplier took
    the
    initial
    sample.
    B)
    If a
    supplier takes
    an Agency-required
    confirmation
    sample for
    lead
    or
    copper,
    the
    supplier must
    average
    the
    results
    obtained from
    the
    initial sample
    with
    the results
    obtained
    from the
    confirmation
    sample in
    determining
    compliance
    with the
    Agency-specified
    lead
    and
    copper MPCs.
    ±)
    Any
    analytical result
    below
    the
    MDL
    must
    be
    considered
    as zero
    for the
    purposes
    of averaging.
    ii)
    Any value
    above the
    MDL
    but
    below the PQL must
    either
    be
    considered
    as
    the
    measured value
    or
    be
    considered one-half
    the PQL.
    b)
    Monitoring
    frequency
    after system exceeds
    tap
    water
    action level.
    A
    supplier
    that exceeds
    the
    lead
    action level or
    the copper
    action
    level in
    tap
    sampling
    must collect one
    source
    water sample
    from each entry
    point to
    the
    distribution
    system
    within no later
    than six
    months
    after the
    excccdcncc.
    end of
    the monitoring
    period during
    which the
    lead
    or copper
    action level
    was
    exceeded.
    For
    monitoring periods
    that
    are annual or
    less
    frequent,
    the end of
    the
    monitoring
    period is
    September
    30 of the calendar
    year in
    which the
    sampling
    occurs,
    or if the Agency
    has established

    The
    calibration
    curve must
    encompass
    the regulatory MRL
    concentration.
    Data may be
    reported
    for concentrations
    lower
    than the regulatory
    MRL
    as
    long

    analyzing
    an MRL check
    standard
    at
    the
    lowest
    reporting limit
    chosen
    by the laboratory.
    The laboratory
    must
    verify
    the
    accuracy of the calibration
    curve at the
    MRL
    concentration by
    analyzing
    an
    MRL
    check standard
    with
    a concentration
    less
    than
    or equal to 110%
    of
    the MRL
    with
    each
    batch of samples.
    The
    measured
    concentration
    for the MRL
    check
    standard
    must
    be
    ±50%
    of the expected
    value,
    if
    any
    field
    sample
    in the
    batch has
    a
    concentration
    less than five
    times the
    regulatory
    MRL.
    Method
    requirements
    to analyze higher
    concentration
    check
    standards and
    meet tighter
    acceptance
    criteria
    for them must
    be
    met in
    addition
    to the MRL
    check standard
    requirement.
    xiii)
    When

    of this
    Section, to
    calculate the TTHM
    or HAA5 concentrations,
    respectively,
    a zero is
    used for any
    analytical result
    that is less than
    the MRL
    concentration
    for that DBP, unless
    otherwise
    specified by
    the Agency.
    3)
    A party
    approved
    by
    USEPA
    or the Agency
    must measure daily
    chlorite
    samples
    at
    the entrance
    to
    the
    distribution
    system.

    This
    subsection
    corresponds
    with 40 CFR
    141.21(f)
    (4),
    which
    USEPA has

    reserved.
    This
    statement
    maintains structural
    consistency
    with the
    federal
    regulations.
    e)
    Suppliers
    must 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
    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,

    4)
    Suppliers need only
    determine
    the presence
    or absence of fecal
    coliforms;
    a
    determination
    of fecal
    coliform
    density
    is not required.
    f)
    Suppliers must
    conduct analysis
    of E.
    coli in accordance
    with one of
    the
    following
    analytical
    methods, incorporated
    by
    reference
    in
    Section
    611.102:
    1)
    EC
    medium supplemented
    with
    50
    ag/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 pg/l MUG is
    commercially
    available.
    At least
    10 ml
    of
    BC 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
    pg/l MUG
    (final
    concentration),
    as
    described in
    Standard
    Methods,
    19th ed. and 20th
    ed.:
    Method 9222
    G.
    This
    test
    is used to
    determine
    if
    a total
    coliform-positive
    sample, as determined
    by the
    MF
    technique,
    contains E.
    coli.
    Alternatively,
    Standard
    Methods, 18th
    ed.:
    Method
    9221
    B may be used if
    the membrane
    filter containing
    a total coliform
    positive
    colony
    or colonies
    is transferred
    to
    nutrient agar,
    as described
    in
    Method 9221
    B (paragraph
    3),
    supplemented with
    100 pg/l MUG .
    If Method
    9221 B
    is used, incubate
    the
    agar
    plate
    at 35° Celsius
    for
    four hours, then
    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
    GNPG-MUG
    (MMO-MUG)
    Test,
    as set
    forth in Appendix
    U
    of
    this
    Part.
    (The
    Autoanalysis
    Colilert
    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 six-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.

    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.

    Arsenic.
    BOARD NOTE: If ultrasonic nebulization is
    used
    in
    the determination of arsenic
    by
    Methods 200.7, 200.8, or Standard Methods, 18th,
    l9th,—e*
    20th, or 21st ed.,
    3120 B, the arsenic must be in the pentavalent
    state to provide uniform signal
    response. For methods 200.7 and 3120 B, both samples
    and standards must be
    diluted in the same mixed acid matrix concentration of nitric
    and hydrochloric
    acid with the
    addition
    of 100 p1 of 30 hydrogen peroxide per 100 ml
    of
    solution.
    For direct
    analysis of arsenic with method 200.8 using ultrasonic
    nebulization, samples
    and standards must contain one mg/l of sodium
    hypochlorite.
    A)
    Inductively-coupled plasma.
    BOARD NOTE: Effective January 23, 2006,
    a supplier may no longer employ
    analytical methods using the ICP-AES
    technology because the detection limits for
    these methods are 0.008 mg/l or higher. This
    restriction means that the two
    ICP-AES methods
    (USEPA
    Environmental Metals Method
    200.7 and Standard Methods,
    Method
    3120
    B)
    approved
    for
    use

    0.05
    mg/i may not be
    used for
    compliance
    determinations
    for
    the revised
    MCL of 0.010
    mg/i. However,
    prior
    to
    the
    2005 through
    2007 compliance
    period,
    a supplier may
    have compliance samples
    analyzed
    with
    these less sensitive
    methods.

    Amended at 33 Iii. 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.
    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),
    which
    requires monitoring for the repealed old MCL for nitrate
    at a frequency
    specified by the state. The Board has followed the USEPA lead and repealed
    that
    old MCL. This statement maintains structural consistency with USEPA rules.
    4)
    This subsection
    (a) (4)
    corresponds with 40 CFR
    141.23(1) (4)
    , which
    authorizes the state to determine compliance and initiate enforcement action.
    This statement
    maintains
    structural consistency with USEPA rules.
    b)
    If the
    result
    of an analysis made under subsection
    (a)
    of this Section
    indicates that
    the level
    of any contaminant listed in Section 611.300 exceeds
    the old
    MCL, the
    supplier must report to the Agency within seven 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,
    rounded
    to
    the same
    number of
    significant
    figures as the old MCL for
    the
    substance in question, exceeds
    the
    old MCL,
    the supplier must notify the
    Agency
    and give notice
    to
    the
    public
    pursuant
    to Subpart V 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
    Cd)
    corresponds with 40 CFR
    141.23(o),
    which pertains
    to
    monitoring for the repealed old MCD for nitrate.
    This statement maintains
    structural consistency with USEPA rules.
    e)
    This subsection
    Ce)
    corresponds with 40 CFR 141.23(p), which pertains
    to
    the use
    of existing data up until a date long since expired.
    This statement
    maintains structural consistency with USEPA 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,

    Sanitary Surveys for GWS
    Suppliers
    a)
    A
    GWS supplier must
    provide the Agency,
    at the Agency’s request, any
    existing information
    that will enable the Agency
    to conduct a sanitary
    survey.
    b)
    For the
    purposes
    of this Subpart
    5, a “sanitary survey,”
    as
    conducted
    by
    the Agency, includes but is not limited
    to, an onsite review of the
    delineated
    WHPA5 (identifying sources of contamination
    within the WHPA5 and
    evaluations or—
    of the hydrogeologic sensitivity of the
    delineated WHPA5 conducted
    under source
    water assessments or utilizing other relevant
    information where
    available)
    facilities, equipment, operation, maintenance,
    and monitoring
    compliance of
    a
    public water system to evaluate the
    adequacy of the system,
    its sources and
    operations and the distribution of
    safe drinking water.
    c)
    The sanitary survey must include
    an evaluation of the applicable
    components listed in subsections
    (c)
    (1)
    through
    (c) (8)
    of this
    Section:

    Agency requirements.
    d)
    The Agency must repeat the
    sanitary survey
    as
    follows:
    1)
    The Agency must conduct
    a sanitary survey that addresses
    the eight
    sanitary survey components listed in
    subsection
    (c)
    of this Section
    no less
    frequently than
    every
    three years for
    a
    CWS
    supplier, except
    as
    provided
    in
    subsection
    (d)
    (3)
    of
    this Section, and every
    five years for a non-CWS
    supplier.
    The Agency may conduct
    more frequent sanitary
    surveys for any supplier.
    The
    initial sanitary survey for
    each community water
    system must be conducted
    before
    December 31, 2012, unless the
    supplier meets the requirements
    of subsection
    (d) (3)
    of this Section. The initial
    sanitary survey for each CWS
    supplier that
    meets
    the requirements
    of subsection
    (d)
    (3)
    of this Section and for
    each non-CWS
    supplier must
    be
    conducted
    before December
    31, 2014. The sanitary
    survey must
    include
    an
    evaluation of each
    of
    the
    elements
    set
    forth
    in subsection
    Cc)
    of
    this Section,
    as
    applicable.
    2)
    The Agency
    may use
    a
    phased
    review process
    to
    meet the requirements
    of
    subsection
    (d)
    (1) of this
    Section
    if
    all the applicable

    3)
    The
    Agency may
    conduct
    sanitary surveys
    once every five years
    for
    community water
    systems
    under any
    of the following
    circumstances:
    A)
    If the
    system either provides
    at
    least 4-log treatment
    of viruses (using
    inactivation,
    removal, or an
    Agency-approved
    combination of
    4-log inactivation
    and
    removal)
    before
    or
    at the
    first customer for
    all its groundwater
    sources;
    or
    B)
    If the
    supplier
    has
    an outstanding
    performance
    record, as determined
    by
    the Agency
    and documented
    in previous sanitary
    surveys,
    and the supplier
    has
    no
    history
    of
    total coliform
    MCL or monitoring
    violations under
    Sections 611.521
    through
    611.527
    since the last
    sanitary survey.

    Groundwater
    Source Microbial
    Monitoring
    and Analytical
    Methods
    a)
    Triggered
    source water monitoring.
    1)
    General requirements.
    A GWS supplier
    must conduct
    triggered source
    water
    monitoring
    if the
    following
    conditions exist:
    A)
    The
    supplier
    does
    not
    provide
    at least 4-log
    treatment of viruses
    (using
    inactivation,
    removal, or
    an Agency-approved
    combination
    of
    4-log virus
    inactivation
    and removal)
    before or at
    the first customer
    for each groundwater
    source;
    and
    B)
    The
    supplier is
    notified
    that
    a sample collected
    pursuant to
    Section
    611.521
    is
    total coliform-positive,
    and the sample is
    not invalidated
    by the
    Agency
    pursuant
    to Section 611.523.
    2)
    Sampling
    requirements.
    A GWS
    supplier must
    collect,
    within 24 hours
    after
    notification
    of the total
    coliform-positive
    sample,
    at least
    one groundwater
    source sample from each groundwater
    source in use at the time
    the total
    coliform-positive sample was
    collected pursuant to Section
    611.521, except as
    provided in subsection
    (a)
    (2)
    (B)
    of this Section.
    A)
    The Agency may, by
    a SEP issued pursuant
    to Section 611.110, extend the
    24-hour time limit on a
    case-by-case basis if it determines
    that the supplier
    cannot collect the groundwater
    source water sample within
    24 hours due to
    circumstances beyond the
    supplier’s control. In the
    case of an extension, the
    Agency must specify how much
    time the supplier has
    to collect the sample.
    B)
    If approved by the Agency,
    a supplier with more than
    one groundwater
    source may meet the requirements of
    this subsection
    (a) (2)
    by sampling a
    representative groundwater source or sources.
    If directed
    by
    the Agency
    by a
    SEP issued pursuant to Section 611.110, the
    supplier must submit for Agency
    approval
    a triggered source water monitoring
    plan that identifies one or
    more
    groundwater sources that are representative
    of each monitoring site in
    the
    system’s sample siting plan pursuant
    to Section 611.521 and that the
    system
    intends to use for representative sampling
    pursuant to this
    subsection
    (a)
    C)
    A GWS supplier that serves 1,000 or
    fewer people may
    use a
    repeat
    sample
    collected from a groundwater source
    to
    meet
    both the requirements of
    Section
    611.522 and to satisfy the monitoring requirements
    of subsection
    (a)
    (2)
    of this
    Section for that groundwater source only if
    the Agency approves the
    use of E.
    ccli as a fecal indicator for source water
    monitoring pursuant
    to
    this
    subsection
    (a)
    by a SEP issued pursuant
    to Section 611.110. If the repeat
    sample collected from the groundwater
    source is E.coli positive, the
    system must
    comply with subsection
    (a) (3)
    of this
    Section.
    3)
    Additional requirements. If
    the Agency does not require
    corrective action
    pursuant to Section 611.803
    (a) (2)
    for
    a fecal indicator-positive
    source water
    sample collected pursuant to subsection
    (a) (2)
    of this Section that is
    not
    invalidated pursuant to subsection
    (d)
    of this
    Section, the system must
    collect
    five
    additional source water samples from the
    same source within 24 hours
    after
    being notified of the
    fecal indicator-positive sample.
    4)
    Consecutive and wholesale
    systems.
    A)
    In addition to the other requirements
    of this subsection
    (a),
    a
    consecutive GWS supplier that has
    a total coliform-positive sample
    collected
    pursuant to Section 611.521 must notify
    the wholesale systems within
    24 hours
    after being notified of the total
    coliform-positive sample.
    B)
    In addition to the other requirements
    of this
    subsection
    (a),
    a wholesale
    GWS supplier must comply with the
    following requirements:
    i)
    A wholesale GWS supplier
    that receives notice from
    a consecutive system it
    serves that a sample collected pursuant
    to Scction Section 611.521
    is total
    coliform-positive must, within 24 hours
    after being notified,
    collect a sample
    from its groundwater sources pursuant
    to subsection
    (a)
    (2) of
    this Section and
    analyze it for a fecal indicator pursuant
    to subsection
    (c)
    of
    this Section.
    ii)
    If the sample
    collected pursuant
    to subsection
    (a) (4) (B) (i)
    of this
    section is fecal indicator-positive,
    the wholesale
    GWS supplier must notify
    all
    consecutive systems served
    by that groundwater source
    of the fecal indicator
    source water positive within
    24 hours of being notified
    of the groundwater
    source sample monitoring result
    and must meet the requirements
    of subsection
    (a) (3)
    of this Section.
    5)
    Exceptions to the triggered source
    water monitoring requirements.
    A GWS
    supplier is not required
    to
    comply with
    the source water
    monitoring requirements
    of subsection
    (a)
    of this Section if either
    of the following conditions
    exists:
    A)
    The Agency determines, and documents in writing,
    by a SEP issued pursuant
    to Section 611.110,
    that
    the total coliform-positive
    sample collected pursuant
    to Section 611.521 is caused by a distribution
    system deficiency; or
    B)
    The total coliform-positive sample collected
    pursuant to Section 611.521
    is
    collected at a location that meets Agency
    criteria for distribution
    system
    conditions that will cause total coliform-positive
    samples.
    b)
    Assessment source water monitoring.
    If directed
    by
    the Agency
    by a SEP
    issued pursuant to Section 611.110,
    a
    GWS
    supplier must conduct assessment
    source water monitoring that meets Agency-determined
    requirements for
    such
    monitoring. A GWS supplier conducting
    assessment source water monitoring
    may
    use a triggered source water sample
    collected pursuant
    to
    subsection
    (a) (2)
    of
    this Section
    to
    meet the requirements
    of subsection
    (b)
    of
    this Section.
    Agency-determined assessment
    source water monitoring requirements
    may include
    the following:
    1)
    Collection of a total of 12 groundwater
    source samples that represent
    each
    month the system provides groundwater
    to the public;
    2)
    Collection of samples from each well,
    unless the system obtains written
    Agency approval to conduct monitoring
    at one or more wells within the GWS
    that
    are
    representative
    of multiple wells used
    by
    that
    system and which draw water
    from
    the same
    hydrogeologic
    setting;
    3)
    Collection of
    a standard sample volume of
    at least 100 ml for fecal
    indicator analysis, regardless of the fecal indicator
    or analytical method
    used;
    4)
    Analysis of all groundwater source samples
    using one of the analytical
    methods listed in subsection
    (C) (2)
    of this
    Section for the presence of E.
    coli,
    enterococci, or coliphage;
    5)
    Collection of groundwater
    source samples
    at a
    location
    prior to any
    treatment of the groundwater
    source unless the Agency
    approves a sampling
    location after treatment;
    and
    6)
    Collection of groundwater
    source samples at the well itself,
    unless the
    system’s configuration
    does
    not
    allow for sampling
    at
    the well
    itself and the
    Agency approves an alternate sampling
    location by
    a
    SEP issued
    pursuant to
    Section 611.110 that is representative
    of the water quality
    of that well.
    c)
    Analytical methods.
    1)
    A GWS supplier subject
    to
    the
    source water monitoring requirements
    of
    subsection
    (a)
    of this Section must collect
    a standard sample volume
    of at least
    100 ml for fecal indicator analysis, regardless
    of the fecal indicator or
    analytical method used.
    2)
    A GWS supplier must
    analyze all groundwater
    source samples collected
    pursuant to
    subsection
    (a)
    of this Section using
    one of the analytical methods
    listed
    in subsections

    Limitation on methods
    use. The time from sample
    collection to initiation
    of analysis may
    not exceed
    30 hours. The GWS
    supplier is encouraged
    but
    is not
    required
    to hold
    samples
    below 10°C during transit.
    d)
    Invalidation of a fecal indicator-positive
    groundwater source sample.
    1)
    A GWS supplier may obtain Agency invalidation
    of a fecal indicator-
    positive groundwater source sample collected
    pursuant to subsection
    (a)
    of
    this
    Section only under either of the following
    conditions:
    A)
    The supplier provides the Agency with written
    notice from the laboratory
    that improper sample analysis occurred; or
    B)
    The Agency determines and documents in writing
    by a SEP issued pursuant
    to
    Section 611.110 that there is substantial evidence
    that a fecal indicator-
    positive
    groundwater source sample is not related
    to source water quality.
    2)
    If the Agency invalidates
    a fecal indicator-positive
    groundwater source
    sample, the GWS supplier must
    collect another source water
    sample pursuant to
    subsection
    (a)
    of this Section within
    24 hours after being notified
    by the
    Agency of its invalidation decision,
    and the supplier must have it
    analyzed for
    the same fecal indicator using the analytical
    methods in subsection
    (c)
    of this
    Section. The Agency may extend the 24-hour
    time limit on a case-by-case
    basis
    if the supplier cannot collect the source water
    sample within 24 hours
    due to
    circumstances beyond its control. In the
    case of an extension, the Agency
    must
    specify how much time the system has
    to collect the sample.
    e)
    Sampling location.
    1)
    Any groundwater source sample required
    pursuant to subsection
    (a)
    of this
    Section must be collected
    at a
    location prior
    to any treatment of the
    groundwater source unless the Agency approves
    a sampling location after
    treatment.
    2)
    If the
    supplierTs
    system configuration
    does not allow for sampling
    at the
    well itself,
    it may collect a sample
    at

    Section
    611.920
    General Requirements
    a)
    USEPA has designated
    that the requirements
    of this Subpart W
    constitute
    National
    Primary Drinking
    Water Regulations.
    The
    regulations
    in this
    Subpart W
    establish monitoring
    and other
    requirements
    for identifying
    Subpart Y
    compliance
    monitoring locations
    for determining
    compliance
    with maximum
    contaminant levels
    for
    TTHM5
    and
    HAA5.
    The supplier must
    use an
    initial distribution
    system
    evaluation
    (IDSE)
    to
    determine
    the locations
    in its
    distribution system
    that are
    representative
    of
    high TTHM
    and HAAS
    concentrations throughout
    the supplier’s
    distribution
    system.
    An
    IDSE
    is
    used in
    conjunction with,
    but
    separate from,
    Subpart
    I compliance
    monitoring,
    to identify
    and select Subpart
    Y compliance
    monitoring
    locations.

    it
    fulfills
    any
    of
    the
    following conditions:
    1)
    The supplier
    owns
    or
    operates
    a
    community
    water system that
    uses a primary
    or
    residual
    disinfectant
    other than ultraviolet
    light;
    2)
    The
    supplier delivers
    water
    that has
    been treated with
    a primary
    or
    residual disinfectant
    other
    than
    ultraviolet
    light; or
    3)
    The supplier owns
    or
    operates
    a
    non-transient
    non-community water
    system
    that serves
    at
    least
    10,000
    people, and it
    either
    uses
    a primary or
    residual
    disinfectant
    other than ultraviolet
    light, or
    it delivers
    water that has been
    treated with
    a
    primary
    or
    residual
    disinfectant
    other than
    ultraviolet
    light.

    611.923 before the date indicated in
    the applicable of subsections
    (a)
    (1)
    through
    (a) (4)
    of this Section.
    Gfl)
    If, within three months after the
    due date for submission of the lOSE
    report identified in this subsection
    (c) (1)
    (nine
    months after this
    date
    if
    the
    supplier must comply on the schedule in subsection
    (c) (1) (C)
    of this
    Section),
    the
    Agency
    does
    not
    approve the supplier’s IDSE report
    or notify the supplier
    that it has not
    yet completed its review, the supplier may consider
    the report
    that it submitted
    to
    the Agency,
    and the supplier must implement the
    recommended
    Subpart Y monitoring
    as
    required.
    2)
    For the purpose of determining the applicable
    compliance schedule in
    subsection
    (c) (1)
    of this Section, the Agency
    may, by a SEP issued pursuant
    to
    Section 611.110, determine that
    a
    combined distribution
    system
    does
    not include
    certain
    consecutive
    systems based on such factors
    as the receipt of water from
    a
    wholesale system only
    on an emergency basis or
    the receipt of only a small
    percentage and small volume
    of water from a wholesale
    system. The Agency may
    also determine, by a SEP issued pursuant to Section
    611.110, that a combined
    distribution system does not include certain wholesale
    systems based on such
    factors
    as
    the delivery of water to a consecutive
    system only on an emergency
    basis or the delivery of only
    a
    small percentage
    and small volume of water
    to a
    consecutive system.
    d)
    A supplier must do one of the following:
    it must conduct standard
    monitoring that meets the requirements in Section 611.921;
    it must conduct a
    system-specific study that meets the requirements in Section
    611.922; it must
    certify to the Agency that it meets the 40/30 certification
    criteria under
    Section 611.923; or it must qualify for
    a
    very small
    system waiver under Section
    611.924.
    1)
    The supplier must have taken the full complement
    of routine TTHM and HAAS
    compliance samples required of a system that serves
    the appropriate population
    and which uses the
    appropriate
    source water under Subpart
    I
    of this
    Part
    (or
    the
    supplier must have taken the full complement of reduced TTHM and T-{AAS
    compliance
    samples required of a system with the supplier’s population
    and source water
    under Subpart I of this Part if the supplier meets reduced monitoring
    criteria
    under Subpart I of this
    Part)
    during the period specified in
    Section 611.923
    (a)
    to meet the 40/ 30 certification criteria in Section 611.923. The
    supplier must
    have taken TTHM and
    HAAS
    samples under Sections 611.381 and 611.382
    to be
    eligible for the
    very
    small system waiver in Section 611.924.
    2)
    If the supplier has not taken the required samples, the supplier
    must
    conduct standard monitoring that meets the requirements in Section

    each
    incorporated
    by
    reference
    in Section 611.102.
    1)
    The supplier must analyze
    at least a 10 1 sample or
    a
    packed
    pellet volume
    of at
    least 2 ml
    as
    generated
    by the methods listed in subsection
    (a)
    of this
    Section. A supplier unable
    to process a 10 1 sample must analyze
    as
    much
    sample
    volume

    of this Section.
    d)
    Sampling location. The sampling location must
    meet the conditions in
    Section 611.1003.
    e)
    Sampling frequency.
    Cryptosporidium samples were collected no less
    frequently than each
    calendar month on a regular schedule, beginning
    no earlier
    than January 1999.
    Sample collection intervals may vary for the conditions
    specified in Section 611.1002(b)
    (1)
    and
    (b) (2)
    if the supplier provides
    documentation of the
    condition when reporting monitoring results.
    1)
    The Agency may,
    by a
    SEP issued
    pursuant to Section 611.110, approve
    grandfathering of previously collected
    data where there are time
    gaps
    in the
    sampling frequency
    if the
    supplier conducts additional monitoring that
    the
    Agency has
    specified
    by a SEP issued pursuant
    to
    Section 611.110
    to
    ensure that
    the data used to
    comply
    with the initial source water monitoring requirements
    of
    Section
    611.1001(a)
    are
    seasonally representative and unbiased.
    2)
    A supplier may grandfather previously collected
    data
    where the sampling
    frequency within each month varied. If the Cryptosporidium sampling frequency
    varied, the supplier must follow the monthly averaging procedure in
    Section
    611.1010(b) (5)
    or Section
    611.1012(a) (3),
    as
    applicable, when calculating
    the
    bin classification for a filtered system supplier or the mean Cryptosporidium
    concentration for
    an
    unfiltered system supplier.
    f)
    Reporting
    monitoring
    results for grandfathering. A supplier that requests
    to grandfather
    previously
    collected monitoring results must report the following
    information by the applicable dates listed in this subsection. A supplier must
    report this
    information
    to the Agency.
    1)
    A supplier
    must
    report that it intends to submit previously collected
    monitoring
    results for grandfathering.
    This report must specify the number of
    previously
    collected results the
    supplier will submit, the dates of the first
    and last
    sample, and whether
    a supplier will conduct additional source water
    monitoring to meet
    the requirements
    of Section 611.1001
    (a)
    . The supplier must
    report this
    information
    no later than the applicable date set forth in Section
    611.1002.
    2)
    A supplier
    must
    report previously collected monitoring results for
    grandfathering, along with the associated documentation listed in subsections
    (f) (2) (A)
    through
    (f) (2) (D)
    of this Section, no later than two months after
    the
    applicable date listed in Section
    611.1001(c)
    A)
    For each sample result, a supplier must report the applicable
    data
    elements in Section 611.1006.
    B)
    A supplier must certify that the reported
    monitoring results include all
    results that it generated during the time period beginning
    with the first
    reported result and ending with the final reported result. This applies
    to
    samples that were collected from the sampling location specified for source
    water monitoring pursuant to this Subpart Z, which were not spiked, and which
    were analyzed using the
    laboratoryTs
    routine process for the analytical methods
    listed in this Section.
    C)
    The supplier must certify that the samples were representative of
    a
    plants source waters and the source waters have not changed. It must report
    a
    description of the sampling locations, which must address the position of
    the
    sampling location in relation to its water sources and treatment processes,
    including points of chemical addition and filter backwash recycle.
    ID)
    For Cryptosporidium samples, the laboratory or laboratories that analyzed
    the samples must provide a letter certifying that the quality control criteria
    specified in the methods listed in subsection
    (c) (1)
    of this Section
    were met
    for each sample batch associated with the reported results. Alternatively,
    the
    laboratory
    may
    provide
    bench sheets and sample examination report forms for
    each
    field, matrix spike, initial precision
    and recovery, ongoing precision and
    recovery, and method blank sample
    associated with the reported results.
    g)
    If the Agency determines that
    a
    previously
    collected data set submitted
    for grandfathering
    was
    generated during source water
    conditions that were not
    normal
    for the
    supplier,
    such as
    a
    drought,
    the
    Agency
    may, by a
    SEP issued
    pursuant
    to Section
    611.110,
    disapprove
    the
    data.
    Alternatively,
    the Agency
    may, by
    a SEP issued
    pursuant
    to Section
    611.110,
    approve
    the
    previously
    collected
    data if
    the
    supplier
    reports
    additional
    source
    water monitoring
    data,
    as
    determined
    by
    the
    Agency,
    to
    ensure that
    the
    data
    set used
    pursuant
    to
    Section
    611.1010
    or
    Section
    611.1012
    represents
    average
    source
    water
    conditions
    for the
    supplier.
    h)
    If
    a supplier
    submits
    previously
    collected
    data
    that fully
    meet
    the number
    of
    samples
    required
    for
    initial
    source water
    monitoring
    pursuant
    to Section
    611.1001(a),
    and some
    of
    the data
    are
    rejected
    due to not
    meeting
    the
    requirements
    of
    this
    Section,
    the
    supplier
    must
    conduct
    additional
    monitoring
    to
    replace
    rejected
    data
    on a
    schedule
    that
    the
    Agency
    has
    approved
    by
    a SEP issued
    pursuant
    to Section
    611.110.
    A
    supplier
    is
    not
    required
    to
    begin
    this
    additional
    monitoring
    until two
    months after
    notification
    that
    data have
    been
    rejected
    and
    additional
    monitoring
    is
    necessary.
