Water Improvement Plans

When the DNR completes a draft version of a Water Quality Improvement Plan, the public will have an opportunity to review the draft document and make comments. The DNR will respond to all comments received during the public comment period and include the comments and responses in the Water Quality Improvement Plan. The public can also attend a public meeting, held near the middle of the public comment period, to discuss the Water Quality Improvement Plan with the DNR and partner groups involved in its development.  After the public comment period ends, the DNR will package up the document to submit to the Environmental Protection Agency (EPA) for their approval.  Only after the EPA approves the plan is it considered a Final Water Quality Improvement Plan.

Public Meetings:

ATTENTION: All public meetings involving TMDLs will be replaced by video presentations accompanied by public comment periods until further notice.

September 2, 2021: The public comment period for the Beach Bacteria TMDL - Addendum 1 will be open until October 4, 2021. The public presentation video has been made available on the DNR YouTube Channel
