EA-1854: Final Environmental Assessment

Waste Water Treatment Modifications For Improved Effluent Compliance Project, Brookhaven National Laboratory Upton, New York  

BNL is served by a Sewage Treatment Plant (STP) located in the North Central part of the 5,265 acre facility (Fig. 3). The STP is approved for operation under a State Pollutant Discharge Elimination System (SPDES) Permit issued by New York State (Permit Number NY 0005835). This permit establishes regulatory limits for various chemical constituents contained in the effluents currently being discharged to the Peconic River, a Class C Freshwater, located just to the north of the STP. In July 2009, the New York State Department of Environmental Conservation (NYSDEC) modified BNL’s SPDES permit.
