Piney Point Update – Jan. 7, 2022
The department continues to monitor the three low-volume seepage areas that were observed upslope of the stormwater drainage ditch along the south wall of the NGS-South compartment late on Wednesday, Jan. 5. There continues to be no indication of any concern with the integrity or stability of the stack system, and there are no offsite discharges occurring at this time. There have been no observed increases in the flow rate and it remains contained within the on-site stormwater collection system.
The court-appointed receiver and its contractors continue to coordinate with department engineers and regulatory staff on their response and investigation into the source of the low-volume seepage. As part of these efforts, today, contractors performed hydrophone surveys to aid in identifying the location of the leak. DEP staff are on-site and will continue to monitor site conditions to minimize environmental impacts and to protect human health and safety.
The court-appointed receiver is continuing his work to both manage and undertake final closure of the site. Closure of this facility remains the top priority, which will ensure that the potential threat to environment and surrounding community is eliminated permanently.
Key status updates and response activities (bolded and underlined language reflects changes):
- The site received 0.02 inches of rainfall overnight. Piney Point has received approximately 36.27 inches of rain since the beginning of June 2021. The current storage capacity for additional rainfall at the site is approximately 18.4 inches. This capacity is expected to change with rainfall amounts, as well as adjusted water management activities at the site. At this time, expected rainfall through the end of May 2022 is approximately 15 inches.
- As part of the site's water management efforts, piping of water to the North Regional Water Reclamation Facility resumed Thursday, Sept. 2, 2021, and to date, 11,328,765 gallons have been transferred. Spray evaporation also continues.
- Approximately 269 million gallons are currently held within the NGS-South compartment. Pond level readings are expected to fluctuate due to a host of factors, including rainfall, water management activities and wind/associated waves in the pond.
- Innovative technology has been used for onsite water treatment since April 2021, and is ongoing under the Receiver’s work at the site. As a result of these innovative water treatment practices, nutrients, including Total Phosphorus (TP) and Total Nitrogen (TN), continue to be reduced significantly onsite. To date, approximately 265 tons of TN and 240 tons of TP have been removed from wastewater onsite.

The department finalized its agreement with the court-appointed receiver, supporting his transition into his role to both manage and undertake final closure of the site. This agreement was finalized after a judge issued an order on Aug. 25, 2021, appointing a receivership to serve as an independent third party to oversee management and closure of the Piney Point site. Day-to-day management and operations now come from this receiver. As part of this transition, water treatment will continue and all available options to manage water onsite will continue to be pursued in an attempt to minimize the potential need for any future treated discharges.
