EPA scores potential sites using the Hazard Ranking System; those that score high enough are placed on the National Priorities List.
Current status: Listed on NPL. This site is on EPA's National Priorities List, which identifies the most serious uncontrolled or abandoned hazardous waste sites in the country. Listing triggers federal cleanup authority and funding under CERCLA (the Superfund law).
