    IN THE MATTER OF:
    R74—5
    PROPOSED AMBIENT AIR QUALITY
    )
    STANDARD FOR TOTAL MERCURY
    )
    ORDER OF THE BOARD
    (by
    Mr. Henss):
    On June
    7,
    1974 a proposal was filed with the Pollution
    Control Board requesting the adoption of an ambient air
    quality standard
    for total mercury.
    Subsequently, the
    Proponent Illinois Environmental Protection Agency, requested
    that hearing dates not be scheduled until after the Agency
    had made further preparation for establishing
    a standard
    for total mercury
    in air.
    The Environmental Protec~tionAgency
    now requests that its proposal be withdrawn without prejudice.
    Research
    in this area is not sufficiently advanced
    to enable
    the Agency
    to proceed with its proposal and the Agency now
    states that its 1974 proposal was premature.
    The Agency would
    like to~leave open the possibility of proceeding with such a
    proposal for an ambient air quality standard for total mercury
    when more data has been accumulated and evaluated.
    The motion
    will be allowed.
    It is Ordered
    that the proposal for adoption of an ambient
    air quality standard for total mercury be dismissed without
    prejudice.
