The Integrated Report
The Clean Water Act (CWA) requires states, territories, and authorized tribes to submit reports to the U.S. Environmental Protection Agency (EPA) regarding the health of the nation’s waters. CWA Section 303(d) requires states to develop a list of waterbodies that do not meet water quality standards. CWA Section 305(b) requires states to develop an inventory of waterbodies in the state, assess the water quality of these waters, and submit a report to EPA. The CWA requires both reports to be submitted to EPA every two years. Prior to 2002, each report was submitted separately to EPA. Beginning in 2002, EPA provided the states the opportunity to combine the two reports into a single “Integrated Report”. The EPA guidance helped the states reduce the reporting burden of submitting two separate reports.
