Minnesota counties are required to adopt SSTS ordinances and administer SSTS programs that comply with state rules. Cities and townships may choose to regulate septic systems; if they do, their ordinance must be at least as stringent as the county's. In 2019, approximately 135 city, township, and other local government units in Minnesota (i.e., water management districts, joint powers) had SSTS programs.
Counties and other local governments with SSTS programs enforce rules, review plans, approve permits and inspect new/replacement systems, and ensure compliance when a system owner has been issued a notice of noncompliance. Though they must follow state rules at a minimum, local SSTS ordinances vary across the state. Some require SSTS compliance inspections prior to property transfer, permits for SSTS repair and maintenance, and other obligations over and above state regulations.
The MPCA's role is to:
- Develop technical and compliance criteria for septic systems
- Establish requirements for local SSTS programs
- Certify individuals and license businesses to do SSTS work
- Register treatment products
New! SSTS local program requirements questionnaire
The MPCA initially created this survey to facilitate its local-government assessments. But the questionnaire also asks local governments to self-assess whether local ordinances and procedures are in place and operating in accordance with Minnesota Rules Chapter 7082. Contact your region's SSTS field staff with any question or to schedule local government assessments.
Developing local government ordinances
The MPCA must be notified of proposed ordinances or ordinance amendments 30 days prior to adoption. The following documents can be used to assist LGUs through the ordinance development process.
