SWMU 27 – Capehart WWTP Sludge Drying Beds

The four concrete sludge drying beds are located along the south-eastern side of the domestic sewage treatment plant serving the Capehart housing area. Areas to the northwest and southwest sides of the drying beds are concrete, while the areas to the southeast and northeast are grass and secondary growth vegetation. The area is utilized on a limited basis due to the minimal amount of flow moving through the plant since the operational closure of Naval Station Roosevelt Roads on March 31, 2004 and the transition of the facility into caretaker status. This unit does not manage or generate RCRA hazardous wastes or constituents. NAPR has no knowledge or evidence of systematic and routine releases of hazardous wastes or constituents from this SWMU.
