Clean Water Partnership loan funds at 0% interest are available on an ongoing basis from the MPCA for city installation of, or reloaning to others for, green infrastructure and other types of projects that are called for in TMDLs, WRAPS, and/or local water plans.
TMDL (total maximum daily load) allocations for pollutants are being established for specific water bodies in the state. Cities that hold an MS4 (Municipal Separate Storm Sewer System) permit will have TMDL attainment written into their permit when it is up for review and renewal.
Convene on a regular basis all entities that have been assigned waste load allocations (for point and non-point pollution sources) to coordinate action on reducing waste loads.
Work with all entities to jointly raise money, fund work and measure progress.
Schedule work aimed at completing the TMDL plan within 10 years.

Brooklyn Center - 2 star

Year action initially completed:
The City of Brooklyn Center has worked with the Shingle Creek & West Mississippi Watershed Management Commision TAC and neighboring communities on the Shingle Creek Chloride TMDL. Improved practices for applying road salt have been made and the TAC just completed a 5-five year review of practices. The City has also worked with the watershed and Twin Lake and Ryan Lake TMDL and a 5-year review has been conducted as well.
Miller creek has a TMDL for temperature. As developments are done in the watershed the stormwater engineer works to insure there are BMPs in place to help reduce temperature.
There are 11 draft TMDLs the MPCA is working on and should be finalized in the near future, 7 for Bacteria Impairments and 4 for Total Suspended Solids (TSS). Also, the city is part of a team that has been working with the MPAC to insure there is a workable solution to the impairments and finalize the TMDLs.
The Bassett Creek Watershed Management Commission (BCWMC), of which Golden Valley is a member, has a Total Maximum Daily Load (TMDL) plan for Sweeney Lake. The Main Stem of Bassett Creek was included in the Minnesota Pollution Control Agency (MPCA)’s Upper Mississippi River Bacteria TMDL and Protection Plan which was approved by the United States Environmental Protection Agency in 2014 and addresses the impairment due to fecal coliform. TMDL plans are carried out through the BCWMC’s and individual member cities’ Capital Improvement Programs and Surface Water Management Plans.
All members of the BCWMC meet on a monthly basis to make sure TMDL implementation plans are being carried out. Golden Valley residents provide funding for BCWMC projects, including TMDL plans, through taxes collected by Hennepin County.
Outcome measures/metrics/money saved:
In 2014, as a result of the coordinated efforts of the BCWMC, the City of Golden Valley, the City of Minneapolis, Minneapolis Parks and Recreation Board, and the MPCA to implement a TMDL plan, Wirth Lake was delisted from the Impaired Waters List.
The City of Maplewood in partnership with the Ramsey Washington Watershed District and other stakeholders have been working to decrease the Nitrogen and phosphorus loads in the Phalen-Casey chain of lakes. The city and their partners have been working on projects to meet these nutrient load reduction goals.
There has also been projects done that help determine the amounts of runoff entering Wakefield Lake and what can be done to prevent this.

Minnehaha and Richfield-Bloomington watershed districts have general chloride and phosphorus reductions plans and TMDLs. No bodies of water in Richfield are on the state's impaired waters list.
A small part of Richfield is part of the Nine Mile Creek Watershed District. The watershed district published a TMDL report in 2010 stating that cities must reduce salt application rates by 62%. The first step was staff training that was provided by the watershed district. From there the City made the following changes to reduce the amount of salt applied to streets:
• Calibration of salters
• Apply salt according to pavement temp
• Using alternative types of salt
Outcome measures/metrics/money saved:
After implementing a salt reduction program in 2010, city staff have been able to reduce salt application rates by more than 1/3, going from 1,500-1,600 tons used per season to around 1,000 tons.
The City of Victoria has implemented a TMDL plan for four of its lakes. Lake Wasserman, Lake Virginia, Tamarack Lake, and Stieger Lake all have TMLD plans and the City works with the Watershed District to make sure it the TMDLs implementation plans are being applied.
