    DISSENTING OPINION (by J. Theodore Meyer):
    I dissent from the majority opinion because Mobil Oil Corporation (Mobil Oil) has
    been seeking relief for 10 years for its ammonia nitrogen discharge limits. While I appreciate
    that the discharges have decreased over the years, this variance still allows Mobil Oil to
    discharge at three times the standard limit. Mobil Oil has not convinced me that it has
    diligently researched alternative reasonably available control technology that could effectively
    treat its highly concentrated effluent, other than dilution in the Des Plaines River.
    For these reasons, I respectfully dissent.
    J. Theodore Meyer
    I, Dorothy M. Gunn, Clerk of the Illinois Pollution Control Board, hereby certify that
    the above dissenting opinion was submitted on the 19th day of September 1997.
    Dorothy M. Gunn, Clerk
