Superfund Site Profile
The 100-acre Sinclair Oil Refinery site is situated between the Genesee River and South Brooklyn Avenue, one-half mile south of downtown Wellsville, in Allegany County, New York. The northerly flowing Genesee River forms the eastern and southern boundaries of the site, South Brooklyn Avenue forms the western boundary, and an old refinery access road forms the northern boundary. The site consists of two areas: a 90-acre refinery area and a 10-acre landfill area.
After immediate actions to protect human health and the environment, EPA put the site’s long-term remedy in place. A site inspection by EPA, the New York Department of Environmental Conservation (NYSDEC) and Atlantic Richfield (ARCO), the site’s potentially responsible party (PRP), in June 2012 confirmed that all systems were operating as designed and are protective of human health and the environment. Environmental easements/restrictive covenants are in place on all the site properties.
