In 1986, Atlantic Richfield ceased operations at The Carr Fork Mill. They then retained Anderson Engineering to decommission the mill which formerly processed copper ore, and reclaim the former smelter.

Anderson Engineering oversaw the demolition of the mill and the construction of the mills 00-acre tailings impoundment. With our construction management team, we placed approximately 2 million cubic yards of structural fill, clean cover, and thousands of feet of hydraulic channel for a complete reclamation on time and within budget.

History of the Site

The former International Smelter, located in Tooele County, Utah was one of the Anaconda Company’s primary lead smelters from 1910 through the middle of the 1970’s. In addition to lead processing, the plant also processed copper, zinc and arsenic. At the time of the site reclamation, the 1200-acre site contained remaining smelter buildings, equipment, underground tanks, tailings facilities and tailings impoundments. In addition to remaining physical facilities, soils on site were high in metals, chemicals present in process emissions, and scattered by-products residuals.

Reclamation of the site entailed removing and properly disposing of listed wastes, consolidating plant by-product waste into a waste isolation cell and placing a stabilization cover over approximately 400-acres of impacted areas. Hydraulic structures were designed and installed to protect reclaimed areas. The entire site vegetated with native grasses, forbs and shrubs.

Open to the Public

Today, the area is know as the Pine Canyon Conservation Area. Per the Salt Lake Tribune:

Pine Canyon Conservation Area offers some flat trails through grasses and a view of the west slope of the Oquirrh Mountains. From the trailhead, follow a dirt path to the old road. Turn north and follow to road to make a clockwise loop. On the northeast end of the loop, the trail will turn to the west and the old road turns into dirt tracks. The tracks soon succumb to just a narrow dirt trail. Follow it ontop of the short ridge and follow the trail back toward the trail head to make a loop.
