This application is for Renewal of an NPDES permit to discharge treated process water and untreated cooling water and stormwater from Cheswick Power Station in Springdale Borough, Allegheny County.
The following effluent limitations are proposed for discharge to the receiving waters, known as Tawney Run, Little Deer Creek and the Allegheny River, classified as warm water fisheries with existing and/or potential uses for aquatic life, water supply and recreation. For the purpose of evaluating effluent requirements for TDS, NO2-NO3, fluoride and phenolics, the existing/proposed downstream potable water supply (PWS) considered during the evaluation is Oakmont Borough Municipal Authority, located at 2.4 miles below the discharge point.
