Integrated Water Quality Report to Congress

Prepared Pursuant to Clean Water Act Sections 305(b) and 303(d)

The public comment period for the 2020 Draft of the Integrated Water Quality Report has closed. Responses to submitted comments are now available.

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. Connecticut's Consolidated Assessment and Listing Methodology (CALM) is included in this section of the report in chapter 1.

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.

The 2020 IWQR document was Public Noticed for public comment on May 19, 2020, the comment period was open from May 19,2020 to June 19, 2020. In lieu of a public meeting at 79 Elm Street, Hartford, (due to COVID 19) a public informational meeting took place  via ZOOM on June 5, 2020 from 10:30 AM- 12:00 pm. All comments were received by rebecca.jascot@ct.gov and summarized by CTDEEP staff.
