This report presents the findings of a study of the farm-raised catfish, crab, shrimp, and tuna processing segments of the canned and preserved seafood processing industry for the purpose of developing effluent limitations guidelines and Federal standards of performance for new sources in order to implement Sections 304, 306, and 307 of the Federal Water Pollution Control Act Amendments of 1972 (the Act). The seafood processing plants included in Phase I of this study were those processing farm-raised catfish, crab, shrimp and tuna. Other aquatic and marine species are involved in a subsequent study, which is now underway. Effluent limitations guidelines are set forth for the degree of effluent reduction attainable through the application of the "Best Practicable Control 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 proposed regulations require the best biological 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 represented by aerated lagoons, activated sludge, or dissolved air flotation. The recommendations for July 1, 1983 are for the best physical-chemical and biological treatment and in-plant control as represented by reduced water use and enhanced treatment efficiencies in pre-existing systems as well as new systems. Supportative data and rationale for development of the proposed effluent limitations guidelines and standards of performance are contained in this report. |
