The MPCA provides financial and technical assistance to local government and other water resource managers to address nonpoint-source water pollution through the state Clean Water Partnership (CWP) and federal Clean Water Act Section 319 programs. Eligible applicants include tribes, townships, cities, counties, watershed district, watershed management organizations, or joint powers board whose members are townships, cities, or counties.

Nonpoint sources of pollution are unregulated sources that include failing septic systems and runoff from agricultural fields, construction sites, animal feedlots, paved surfaces, and lawns. When taken together, these sources contribute huge quantities of phosphorus, bacteria, sediments, nitrates and other pollutants to the environment. They also represent the largest combined share (an estimated 86%) of the state's water pollution.

The Minnesota Nonpoint Source Management Program Plan is required for Minnesota to remain eligible to receive grant funds under Section 319 of the federal Clean Water Act. But Minnesota's plan goes beyond what is required and outlines a multi-year approach for addressing water quality problems from nonpoint-source pollution.
