MPCA solicits comments on report for Eagan lakes

St. Paul, Minn. — The Minnesota Pollution Control Agency (MPCA) is seeking feedback on a draft water quality improvement report for 12 lakes within the city of Eagan in Dakota County. Public comments will be accepted through May 19, 2015.

Of the 12 lakes discussed in this study, four are considered impaired because they contain excess phosphorus. Bodies of water with excess phosphorus are prone to frequent algae blooms, which interferes with swimming, fishing and recreation. According to the report, phosphorus levels in these lakes must be reduced by up to 54 percent, depending on the lake, to meet state standards.

The remaining lakes, which include two wetlands, are not considered impaired, but actions are proposed to protect these waterbodies to maintain or improve water quality.

The report was undertaken by the city of Eagan using funding under the state Clean Water Partnership program. The report, known as a Total Maximum Daily Load (TMDL), includes federal requirements that quantify pollutant levels in an impaired water body, identify the sources of the pollution and propose ways to bring water quality back to an acceptable level. A detailed management plan, outlining various implementation projects to restore or protect the waterbodies, is included in the report.

After reviewing comments from the public the MPCA will submit a final draft to the U.S. Environmental Protection Agency for approval.

The draft report may be viewed on the agency's Public Notice webpage. For more information or to submit comments, contact Chris Zadak at 651-757-2837, or by mail at MPCA, 520 Lafayette Rd., St. Paul, MN 55155.

Comments must be received in writing at the MPCA office by 4:30pm on May 19, 2015. They must include an explanation of the commenter’s interest in the TMDL report, a clear statement of any recommended changes (including references to specific sections of the report) and specific reasons for any proposed changes.
