MPCA Spring 2020 Bulletin

The Minnesota Pollution Control Agency (MPCA) put out a Bulletin for Subsurface Sewage Treatment System professionals and inspectors regarding COVID-19. The information is also useful for rural property owners to know and may be found online.

Subsurface Sewage Treatment System Program

Most homes and businesses in municipalities discharge their sewage to publicly owned sewage treatment plants. In rural areas, sewage is treated "onsite" utilizing septic tanks and soil treatment areas. These systems are called Subsurface Sewage Treatment Systems (SSTS). In either case, it is extremely important that sewage be treated properly to ensure safe drinking water and safe water recreation, and so that the public is not exposed to health risks from sewage.

Winona County Planning Department through the Zoning Ordinance and authority from the Minnesota Pollution Control Agency regulates the design, permitting, installations, and inspections of Subsurface Sewage Treatment Systems (SSTS).

Loans from AgBMP Program

Agricultural Best Management Practices (AgBMP) Loan Program provides loans to upgrade ISTS systems on rural properties. These loans are available from certain banks within the county.
