Pompton Lakes Work Site
The Pompton Lakes Works (PLW) Site, once an explosive manufacturing facility, covers approximately 570 acres within the Borough of Pompton Lakes, New Jersey. The PLW Site incorporates two drainages, the Wanaque River to the west and the Acid Brook to the east. Acid Brook flows into Pompton Lake, which was formed by damming the Ramapo River. The Wanaque River flows into the Pequannock River, which joins with the Ramapo River downstream of Pompton Lake to form 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 the Wanaque River and have migrated downstream, although the overall nature and extent of contamination has not yet been determined. In October 2013, the Federal trustee for natural resources affected by releases from the PLW Site (The U.S. Department of the Interior or DOI) completed a Preassessment Screen Determination, which concluded that an assessment of natural resource damages is justified.
E.I. duPont de Nemours and Company (DuPont) was the only identified Responsible Party for the PLW Site. The Federal Trustees notified DuPont of their intent to proceed with a Natural Resource Damage Assessment (NRDA) in September 2014.
In April 2014, DuPont and DOI, acting through the U.S. Fish and Wildlife Service and the National Park Service, signed a cooperative agreement to facilitate the collection and sharing of data, and to identify the necessary and appropriate restoration required to resolve natural resource damage claims arising from, or relating to, the PLW Site. In 2015, DuPont created a spin-off corporation, the Chemours Company, which inherited environmental liability associated with the PLW Site. The cooperative agreement remains in effect between DOI and the Chemours Company.
The DOI's Case Team held a public information session in May 2016 to discuss the NRDA process and the status of the PLW Site NRDA.
