The department is accepting written comments on the proposed Missouri 2022 303(d) Impaired Waters List until Jan. 18, 2023. The department will hold two public meetings about the proposed list on Nov. 16, 2022 and Dec. 13, 2022.

The department included prioritizing waters for Total Maximum Daily Load (TMDL) development as part of Missouri's proposed 2022 Section 303(d) Impaired Waters List. Written comments on the proposed 2022 Section 303(d) Impaired Waters List and TMDL prioritization may be submitted by mail to the Missouri Department of Natural Resources, Water Protection Program, Attn: Robert Voss, PO Box 176, Jefferson City, MO 65102-0176, or by email to firstname.lastname@example.org.
Section 303(d) of the federal Clean Water Act requires that each state identify waters not meeting water quality standards and for which adequate water pollution controls have not been required. The 303(d) list helps state and federal agencies keep track of impaired waters not addressed by normal water pollution control programs. The department is required to submit Missouri's proposed 303(d) list of impaired waterbodies to the U.S. Environmental Protection Agency every even numbered year.
