The document describes the technical development of the U.S. Environmental Protection Agency's promulgated effluent limitations guidelines and standards that control the discharge of pollutants into navigable waters and publicly owned treatment works (POTWs) by existing and new sources in the organic chemicals, plastics, and synthetic fibers point source category. The regulation establishes effluent limitations guidelines attainable by the application of the 'best practicable control technology currently available' (BPT) and the 'best available technology economically achievable' (BAT), Pretreatment standards applicable to existing and new discharges to POTWs (PSES and PSNS, respectively), and new source performance standards (NSPS) attainable by the application of the 'best available demonstrated control technology'. The regulation was promulgated under the authority of Section 301, 304, 306, 307, 308, and 501 of the Clean Water Act (the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. 1251 et seq., as amended). It was also promulgated in response to the Settlement Agreement in Natural Resources Defense Council, Inc. v. Train, 8 ERC 2120 (D.D.C. 1976), modified, 12 ERC 1833 (D.D.C.).
