Abstract : The U.S. Military Academy at West Point, NY operates the Target Hill Wastewater Treatment Plant (WWTP), which currently disposes of its residual sludge by landfill. The WWTP uses a belt press, which can dewater sludge up to 14 percent solids content, a level below the 20 percent solids content required by New York State for landfilling. The sludge is consequently mixed with sand to meet the State requirements, a practice that places an unnecessary labor and materials burden on the WWTP. This study developed a strategy to manage Target Hill WWTP sludge more effectively. Factors governing strategy development were: compliance with the USEPA's new Part 503 regulations, economy, and simplicity of operation. Sludge should be stabilized, and stabilized biosolids should be beneficially used as a soil supplement to avoid landfill disposal. The study recommended composting Target Hill WWTP sludge at the Rockland County Solid Waste Management Authority central composting facility currently under construction, and reusing the biosolids as a soil amendment at West Point Military Academy. By implementing this recommendation, Target Hill WWTP will be able to save Operations and Maintenance (O&M) money and to serve as a model installation for Federal and local government cooperation in biosolids management.
