United States August 1980 Environmental Protection Agency Water and Waste Management Industrial Effluent Standards A Major Step in Improving Water Quality ------- ( The Effluent Guidelines Division has the lead in developinq industrial effluent limitations and pre treatment standards that will contrilM.Jte to the restoration and maintenance of the chemical, physical, and biological integrity of the Nation’s waterways. These include those activities man dated by the 1977 Clean Water Act, the specific requirements of the NRDC “Settlement Agreement,” ______ and an expanding involvement in the Agency’s inteqrated waste management and toxics control strategy.

Washitigtuii, D.C. 20460 ------- Although a decade of concerted effort has notably improved many U.S. waterways, the fact remains that over half of our river basins are still affected by pollution. This pollution includes hundreds of elements, ranging from relatively simple algae scums to highly toxic stews of industrial and chemical wastes. The sources of these pollutants are just as diverse—industrial plants, animal feedlots, mining operations, waste treatment facilities, landfills, and agricultural runoff. Among industrial facilities alone, almost 35,000 plants discharge process wastewaters directly into U.S. waterways; another 40,000 plants discharge wastewater to some form of pub- licly owned treatment works. As the kepone disaster in Virginia has taught us, these industrial wastes constitute an environmental time bomb. Improperly or ineffectively treated, they are an invisible threat to public health and safety. Because of their potentially hazardous and pervasive environmental effects, industrial wastes have become the principal focus of pollution control efforts by the Environmental Protection Agency (EPA). This booklet high- lights those aspects of Federal law that deal with industrial pollution. It explains how EPA's Effluent Guidelines Division (EGD) develops limitations for pollutants and applies them to various industries, and also how the public can participate in the devel- opment process.
