The Maryland Department of Natural Resources, Power Plant Research Program (PPRP) coordinates State agency review of new electricity generating units in Maryland. In October 1996, a new natural gas-fired power plant began operating in Prince George`s County, Maryland -- the Panda-Brandywine facility. When Panda Energy Corporation first submitted its application for a license to build and operate the plant, they proposed using 400 million gallons of ground water per year as makeup water for the facility`s cooling towers. PPRP recommended that the company consider instead using treated effluent from one of the two tertiary sewage treatment plants relatively nearby. This paper will describe the chlorination system in place at the sewage treatment plant identified, discuss the issues that had to be resolved between PPRP and Panda to reach agreement on design and operation, and summarize operating experience with respect to the facility`s required reporting to the State. The paper will also report PPRP`s findings regarding the general feasibility of wastewater reuse at power plants in Maryland, under what circumstances it is most beneficial, and what are the most significant concerns from an environmental standpoint.
