Work on USPCI's $90 million hazardous waste incinerator in western Tooele County has been stopped temporarily by the U.S. Department of Interior's Board of Land Appeals.

The board granted a request by three groups to stop the land trade and issuance of federal rights of way needed for the U.S. Pollution Control Inc. incinerator until arguments can be heard on the project's environmental impact statement.Wendover City, the Utah Chapter of the Sierra Club and Utah Wildlife Federation contended the environmental study used to justify the Bureau of Land Management's decision to approve the incinerator did not fully address the risks of such things as transporting waste to the facility, toxic air pollutants, and alternative ways of dealing with the waste.

The board of land appeals is an administrative court within the Department of Interior that considers challenges to decisions made by Interior agencies such as the BLM.

Deane Zeller, Salt Lake BLM district manager, said USPCI has already completed construction of a temporary access road across federal land and can continue to use it.

However, work will be stopped on a partially built power line that crosses BLM land.

USPCI also needs to build a railroad spur, water line, telephone line and well on BLM property. Work on those cannot begin until the board lifts its stay.

USPCI, a subsidiary of Union Pacific Corp., was just beginning to prepare the site for its incinerator near the Clive railroad siding 68 miles west of Salt Lake City.

Work on the incinerator can't begin until the Utah Department of Health issues its waste handling permit, which is expected next spring.

"This is going to temporarily set back some construction activity on the non-regulated portions of the facility," said Joseph A. LaSala, spokesman for USPCI. "It will delay us six or eight weeks, perhaps."

He said the environmental impact statement on the incinerator is "very professionally done and more than adequate to address the issues raised by this project."
