Glass Manufacturing Effluent Guidelines
EPA initially promulgated the Glass Manufacturing Effluent Guidelines and Standards (40 CFR Part 426) in 1974 and 1975, and amended the regulation in 1979 and 1986. The regulation covers direct
direct dischargerA point source that discharges pollutants to waters of the United States, such as streams, lakes, or oceans. and indirectindirect dischargerA facility that discharges pollutants to a publicly owned treatment works (municipal sewage treatment plant). dischargers. The Effluent Guidelines and Standards are incorporated into NPDES permits for direct dischargers and permits or other control mechanisms for indirect dischargers (see Pretreatment Program).
