Twin Cities Metropolitan Area Chloride Total Maximum Daily Load Study

The Minnesota Pollution Control Agency (MPCA) and stakeholders worked together to develop a plan to
achieve the TCMA chloride TMDLs. The CMP incorporates water quality assessment, source
identification, implementation strategies, monitoring recommendations, and measurement and
tracking of results into a performance-based adaptive approach for the TCMA. The goal of the plan is to
develop the framework to assist local partners in minimizing salt (chloride) use and provide safe and
desirable conditions for the public. The CMP also includes performance-based strategies to reduce salt
(chloride) from other sources such as water softening, wastewater discharges, and agricultural sources.
