This document presents the findings of a study of the Ink Manufacturing Industry for the purpose of developing effluent limitations and standards, and pretreatment standards for existing and new sources to implement Sections 301, 304, 306, 307 and 501 of the Clean Water Act. The study covers approximately 460 ink manufacturing facilities in SIC Group 2893. Effluent limitations guidelines are set forth for the degree of effluent pollutant reduction attainable through application of best available technology economically achievable which must be attained. The standards of performance for new sources (NSPS) set forth the degree of effluent pollutant reduction that is achievable through the application of the best available demonstrated control technology. Pretreatment standards for exisiting and new sources (PSES and PSNS) set forth the degree of effluent pollutant reduction that must be achieved in order to prevent the discharge of pollutants that pass through, interfere with, or are otherwise incompatible with the operaton POTW. The proposed regulations for BAT, NSPS, PSES and PSNS are based on application of contract hauling to completly eliminate the discharge of pollutants from ink plants.
