U.S. Pollution Control Inc. is prepared to pay Utah $100,000 to settle state allegations that its hazardous waste landfill operation in western Tooele County violated environmental regulations.

USPCI's Grassy Mountain landfill was cited by state officials in October on claims that liquid wastes were placed in the landfill, which is allowed to accept solid material only. The landfill is not designed to contain liquids, according to the citation.Also, state officials claimed that some material was taken directly to the landfill for disposal without being treated and inspected first, as required by USPCI's permit.

The proposed arrangement was outlined during the meeting of the Utah Solid and Hazardous Waste Committee Friday. USPCI, based in Georgia, has agreed to the settlement.

Under it, the company would make certain it is in compliance with the permit and pay the state $140,000. Kenneth Alkema, director of the Utah Division of Environmental health, said $100,000 of this would be paid as soon as the settlement is approved.
