Final Effluent Guidelines Plan for 2004/2005 New
EPA is publishing a plan and schedule to consider developing and revising effluent guidelines.

Effluent Guidelines

Effluent limitations guidelines and standards are established by EPA for different non-municipal industries. These guidelines are based on the degree of pollutant reduction that can be attained by an industry when they apply recommended pollutant control technologies.

The Clean Water Act requires EPA to specifically develop effluent guidelines that represent the following:

Cooling Water Intake Structures CWA §316(b)

EPA is developing regulations under section §316(b) of the Clean Water Act. Section §316(b) requires that the location, design, construction and capacity of cooling water intake structures reflect the best technology available for minimizing adverse environmental impact. More than 1,500 industrial facilities use large volumes of cooling water from lakes, rivers, estuaries or oceans to cool their plants, including steam electric power plants, pulp and paper makers, chemical manufacturers, petroleum refiners, and manufacturers of primary metals like iron and steel and aluminum.

Cooling water intake structures cause adverse environmental impact by pulling large numbers of fish and shellfish or their eggs into a power plant's or factory's cooling system. There, the organisms may be killed or injured by heat, physical stress, or by chemicals used to clean the cooling system. Larger organisms may be killed or injured when they are trapped against screens at the front of an intake structure.

Uniform National Discharge Standards (UNDS) for Armed Forces Vessels

Uniform national discharge standards (UNDS) are required by Section 312 of the Clean Water Act to regulate discharges incidental to the normal operation of Armed Forces Vessels.
