ILLINOIS POLLUTION CONTROL BOARD
    April

    1988
    IN THE MATTER OF:
    REVISION OF THE FLUORIDE
    )
    R88—13
    DRINKING WATER STANDARD:
    AMENDMENTS TO
    35 ILL.
    ADM.
    CODE
    604.202 AND 604.203
    ORDER OF THE BOARD
    (by
    3.
    Anderson):
    Sections 604.202 and 604.203 of
    the Board’s public water
    supply rules establish maximum allowable concentrations
    (MAC)
    of
    fluoride
    in drinking water
    based on
    a public water supply’s
    geographical location.
    The counties north of and including
    the
    counties of Henderson,
    McDonough,
    Fulton,
    Tazerweil,
    McLean,
    Ford
    and Iroquois
    is 2.0 mg/i, while
    that for counties south of these
    is
    1.8 mg/l.
    The standards contained
    in these
    rules were
    no more
    stringent
    than the standards promulgated by USEPA
    in
    1975.
    On April
    2,
    1986,
    the USEPA amended
    its fluoride regulations
    to establish
    a maximum contaminant
    level of
    4.0 mg/i and a
    secondary maximum contaminant
    level of 2.0 mg/i.
    51 Fed.
    Reg.
    11396—11412.
    The Board
    is opening
    this docket
    to consider relaxation of
    the fluoride standard
    so as
    to be consistent with USEPA
    requirements.
    A technical record was developed
    in the R85—14
    proceeding concerning
    the cosmetic and/or health effects
    from
    consumption
    of water containing fluoride at various levels.
    The
    Board will
    incorporate relevant testimony and materials
    from the
    R85—l4 docket into this one,
    and directs
    the Hearing Officer
    to
    specifically identify such materials
    for introduction as exhibits
    in this proceeding.
    The Board will develop a proposal
    for first notice
    publication
    in the Illinois Register.
    It appears that
    a complete
    proposal would require more than change
    of the number “2.0”
    to
    “4.0”
    in Section 604.202 and deletion of Section 604.203(a).
    As
    briefly discussed
    in the R85—14 proceeding
    (R.330—332),
    it would
    appear that any proposal would
    need
    to incorporate other
    amendments to maintain consistency between
    the state’s regulatory
    program and the federal one.
    While it would appear that
    a
    proposal should include the public notification requirements
    of
    40 CFR Sections 141.32 and 143.5,
    there may
    be other program
    elements which should be added.
    The Board
    is accordingly requesting
    the assistance of the
    Agency
    in analyzing
    the state and federal
    rules
    for the purpose
    8.9—519
    —2—
    of developing
    a comprehensive proposal for first notice
    publication
    to avoid delay which could
    be caused by
    failure
    to
    notice necessary amendments.
    The Board intends
    to expedite this
    proceeding,
    and wishes
    to receive Agency comments
    as early
    as is
    practicable.
    The Board
    is, however,
    aware that the Agency may
    wish
    to take time
    to consult with IJSEPA
    in order
    to fully respond
    to the Board’s request.
    The Board accordingly requests the
    Agency
    to file comments responsive
    to this Order
    on or before May
    23,
    1988;
    if complete comments cannot be
    filed by that date,
    the
    Board would appreciate
    a status report and estimate
    of additional
    time needed.
    IT
    IS SO ORDERED.
    I,
    Dorothy M.
    Gunn,
    Clerk
    of the Illinois Pollution Control
    Board, hereby certify that the above Order was adopted on
    the
    ~/“4day
    of
    _______________,
    1988,
    by
    a vote
    of
    7—o
    41~24F7~.
