Announcement Date: August 10, 2010

2010: The International Refinery and Smelter (IS&R) project, which began in 1987, area is removed from the EPA NPL Superfund listing. The former smelter site is converted to over 1,200 acres of conservation space; known today as the Pine Canyon Conservation Area.

About the IS&R Project: Environmental reclamation and cleanup work was conducted by the PRP at the former IS&R smelter property in the 1980s. Initially, reclamation work consisted of demolition and on site disposal of structures, and waste consolidation of 330 acres of tailings, 28 acres of metal-contaminated slag, 13 acres of settling ponds, 50 acres of landfills and 125 acres of smelting waste. In addition, drainage improvements to prevent erosion, soil capping and re-vegetation were completed to remedy the scars from the former smelter operations. The only remaining feature is the slag pile. The slag pile is inert and stands as a historic marker to the local community. Analysis of samples collected downstream of the slag pile in Pine Creek during the RI indicated that the slag pile was not impacting the water quality within the stream. All analytical results for Pine Canyon Community were found to be within drinking water and ambient water quality standards. Source: EPA 5 Year Review Plan
