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.
