Water Quality Technology Availability Act

HR 3900, the Water Quality Technology Availability Act, amends a key provision of the Federal Water Pollution Control Act to require that pollution limits for industrial discharges be based only on technologies already commercially available in the U.S. This change directly affects industries subject to water quality regulations (like manufacturing and utilities) and the Environmental Protection Agency (EPA) when developing effluent guidelines. The bill modifies Section 304(b)(1)(B) to replace "technology in relation to" with "technology that is commercially available in the United States in relation to," ensuring standards reflect existing, practical solutions. It does not create new requirements but clarifies that regulatory standards must consider only currently available technologies, not hypothetical or undeveloped ones.
