This 640 acre site for hazardous and toxic materials opened in 1982 and employs about 100 people. Laidlaw operated this facility until recently, and it served as a dump site for the toxic ash from Laidlaw’s incinerator, 15 miles away at Clive. One of three waste sites Laidlaw acquired when it bought U.S. Pollution Control Inc. (USPCI), a Union Pacific corporation, in 1994. Grassy Mountain is now owned by Clean Harbors, which acquired Safety Kleen’s numerous hazardous waste sites, landfills and chemical waste incinerators throughout the United States and Canada.

Location: 44 miles E of Wendover, UT
