The Atlantic County Utilities Authority (ACUA) will install a permanent cap over 16 acres of its landfill in Egg Harbor Township. Excavation for the project began on Wednesday, April 2, 2025.
The cap will increase landfill gas collection efficiency, reduce leachate generation, improve stormwater quality, and minimize the potential for odors to migrate off-site.
“This project serves as a literal capstone to the significant investments we’ve made in our landfill gas collection and control system over the last two years,” said ACUA President Matthew DeNafo.
Since 2023, ACUA has invested nearly $2 million in its landfill gas collection and control system, which included the installation of 51 landfill gas collection wells, more than 14,000 linear ft. of gas collection header pipe, 12,000 linear ft. of compressed air line, and two dewatering sumps.
A permanent cap can be applied over areas of the landfill that are no longer accepting waste. The cap is made with geosynthetic plastic liner and covered with soil and grass once completed.
The permanent cap is being installed five years ahead of schedule due to the support of the Atlantic County Executive and Commissioners who approved $7 million in federal American Rescue Plan Act (ARPA) fund appropriations in November 2024.
In addition to this work, the Authority is also reapplying eight acres of temporary cap that was removed in 2024 to place additional waste. The temporary cap will also enhance landfill gas collection efficiency.
Construction details will be shared on ACUA’s website at www.acua.com/landfillgas.
