Pompton Lakes Works Site
The Pompton Lakes Works Site (PLW) covers approximately 570 acres within the Borough of Pompton Lakes, Passaic County, New Jersey. The facility is situated along an intermittent stream, Acid Brook, which enters Pompton Lake along the western bank at a shallow delta called the Acid Brook Delta (ABD). Pompton Lake was formed by the damming of the Ramapo River; about 1.5 miles downstream of the Pompton Lake Dam, the Ramapo River empties into the Pompton River. The Pompton River flows into the Passaic River, which empties into Newark Bay.
Explosives were manufactured at the PLW facility between 1902 and 1994. Hazardous substances including lead and mercury were discharged to Acid Brook and have migrated downstream, although the overall nature and extent of contamination has not yet been determined. The Federal trustee for natural resources affected by releases from the PLW (DOI) recently completed a PAS, which evaluated criteria that must be met for pursuing a NRDAR and concluded that an assessment of natural resource damages is justified.
The DuPont Corporation is the only identified Responsible Party for the PLW. DuPont and DOI, acting through the Service and the National Park Service, have signed a cooperative agreement to facilitate resolution of any natural resource damage and Park System Resource Protection Act claims arising from or relating to the PLW, to minimize the transaction costs associated with such claim(s), and to work toward the goal of cooperatively developing and implementing a final restoration plan.
