The Regional Water Quality Control Board amended U.S. Marine Corps Base Camp Pendleton’s waste discharge requirements for the Las Pulgas Landfill. The 7-0 RWQCB vote Wednesday, Feb. 10, established procedures and technical specifications to remove the existing Phase I unit side slope liner system and to construct the engineered alternative Phase I unit side slope liner system. The revised waste discharge order recognized Marine Corps efforts to implement corrective actions at the landfill and resume waste disposal operations within the Phase I unit.
