This document presents the findings of an extensive study of the fish meal, salmon, bottom fish, clam, oyster, sardine, scallop, herring, and abalone segment of the canned and preserved fish and seafood processing industry of the United States to develop effluent limitations for point source and new source standards of performance in order to implement Sections 304(b) and 306 of the Federal Water Pollution Control Act Amendments of 1972 (the Act). Effluent limitations are set forth for the degree of effluent reduction attainable through the application of the 'Best Practicable Contrl Technology Currently Available' and the 'Best Available Technology Economically Achievable' which must be achieved by existing point sources by July 1, 1977 and July 1, 1983 respectively. The 'Standards of Performance for New Sources' set forth a degree of effluent reduction which is achievable through the application of the best available demonstrated control technology, processes, operating methods or other alternatives. The regulations are based on the best identified primary or physical-chemical treatment technology currently available for discharge into navigable water bodies by July 1, 1977 and for new source performance standards. This technology is generally represented by fine screens and air flotation. The regulations for July 1, 1983 are based on the best identified physical-chemical and secondary treatment and inplant control as represented by significantly reduced water use and enhanced treatment efficiencies in existing systems, as well as new systems. This technology is generally represented by air flotation, aerated lagoons, or activated sludge. Supportive data and rationale for development of the effluent limitations and standards of performance are contained in this report.
