Prepared Pursuant to Clean Water Act Sections 305(b) and 303(d)
The FINAL 2022 Connecticut Integrated Water Quality Report is now available. The public comment period has closed. Responses to submitted comments are now available.
New!!! Web mapping application to view and download IWQR information! As a result of previous public input, this cycle we have developed an online web mapping application that will allow the public to view and download assessment and TMDL information for the 2020 and 2022 cycles. We will continue to use this web application for future cycles.
Every two years (sometimes referred to as a cycle) Connecticut submits the Integrated Water Quality Report to Congress (IWQR). The report covers two sections of the Clean Water Act (CWA), 305 (b) and 303 (d).
Section 305(b) of the Federal Clean Water Act (CWA) requires each State to monitor, assess and report on the quality of its waters relative to designated uses established in accordance with the Connecticut Water Quality Standards.
Section 303(d) of the CWA requires each State to list waters not meeting water quality standards and prioritize those waters for Total Maximum Daily Load (TMDL) development or other management plans for restoration or protection.
Before each IWQR cycle is finalized and submitted to EPA, CTDEEP conducts an informational meeting and offers an opportunity for the public to review and comment on the report for at least 30 days after the report is public noticed.
