The Joslyn Manufacturing & Supply Company (Joslyn) Site is located within the city limits of Brooklyn Center in Hennepin County, Minnesota. The site is now divided into two discrete areas: the 25-acre portion of the site that has been deleted from the National Priorities List (NPL) and redeveloped for commercial use and the 11-acre West Area. The redevelopment of the eastern portion of the Site has occurred since 2000. The westernmost portion of the site, the West Area, remains undeveloped. Middle Twin Lake borders the western perimeter of the West Area of the site. The Joslyn Site was used for wood treating from the 1920s until its closure in 1980. The wood treating process began with a creosote thermal process and, in 1965, it changed to a pressure treating process with pentachlorophenol (PCP) and a water-soluble process using chromated copper arsenic (CCA). Wastes from these processes were placed in waste disposal ponds on the site. Process sludge was also buried on the site. In addition, during the 1950s and 1960s, wood-treating solution spills occurred at the site. Site Responsibility This site is being addressed through state and potentially responsible party (PRP) actions. The site is part of an enforcement deferral agreement between EPA and the Minnesota Pollution Control Agency (MPCA) and all work at the site is overseen by MPCA.
