The document presents the findings of an extensive study of the renderer segment of the meat products industry by the Environmental Protection Agency (EPA) for the purpose of developing effluent limitations guidelines, standards of performance for new sources, and pretreatment standards for the industry, to implement Sections 301, 304(b), 306 and 307(b) and (c) of the Federal Water Pollution Control Act Amendments of 1972 (the 'Act'). The rendering plants included in the study were those plants specifically processing animal by-products at an independent plant (i.e., a plant located, operated and managed separately from meat or poultry slaughtering and packing plants). 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.
