Old Esco site added to EPA cleanup priorities list
EPA and the Texas Commission on Environmental Quality announced the Old Esco site, a former electrical transformer facility in Greenville, Texas, as one among six sites across the nation to be placed in the national Superfund cleanup program. The site was added to the National Priorities List because of elevated concentrations of polychlorinated biphenyls in the soil at the old manufacturing facility and on adjacent properties.
The facility produced electrical transformers from 1945 to 1970 with a process that used oils containing polychlorinated biphenyls. Polychlorinated biphenyls are now known to cause health problems in humans and wildlife, and is a possible carcinogen. The Esco site was proposed to the Superfund list in March 2008.
EPA Superfund works closely with state agencies to clean and restore uncontrolled contaminated properties. To date there have been 1,587 sites listed to the National Priorities List. Of these sites, 329 have been removed from the list leaving 1,258 sites to be completed.
