EPA proposes metal products and machinery effluent discharge guidelines

On Jan. 3, EPA proposed effluent limitation guidelines for wastewater discharges into waterways from the metal products and machinery industry.

Jan. 5, 2001—On Jan. 3, EPA proposed effluent limitation guidelines for wastewater discharges into waterways from the metal products and machinery industry.

When implemented, the proposals are expected to reduce the discharge of 20 pollutants by 170 million pounds per year, improving water quality in more than 1,100 streams.

EPA's proposal for the metal products and machinery industry would establish technology-based effluent limitations and pretreatment standards for wastewater discharges in a number of industries, including aerospace, electronic equipment, hardware, railroad, ship, and stationary industrial equipment. The guidelines would apply to both new and existing facilities that manufacture, rebuild, or maintain finished metal products, parts or machines.

Under the Clean Water Act, EPA develops effluent guidelines specific to individual industries in order to control discharge of pollutants into surface waters and publicly-owned treatment facilities.

The effluent guidelines program has reduced the public health and environmental impacts of pollutant discharges from over 50 industrial categories since the program's inception in 1974.
