This legislation, titled the Water Quality Technology Availability Act, proposes an amendment to the Federal Water Pollution Control Act. Its primary goal is to modify how the Environmental Protection Agency (EPA) develops effluent limitation guidelines , which are standards for wastewater discharge. Specifically, the bill requires the EPA to consider the total cost of applying technology that is commercially available in the United States when setting these guidelines. This clarifies and potentially narrows the scope of technology considered, emphasizing domestic commercial availability and its associated costs in pollution control efforts.
