Due to their permit and ordinance authorities, local units of government are often the first line of action for licensing enforcement activities. The MPCA provides enforcement when local actions are ineffective or local governments or SSTS professionals need assistance. The MPCA investigates written complaints and retains the authority to suspend, restrict or revoke a license. Minnesota rules outline the MPCA authorities for enforcing certification and licensing requirements.

Local units of government that encounter straight-pipe systems in their jurisdiction and need assistance bringing those properties into compliance can contact the MPCA. Minnesota Statute 115.55 subjects homeowners who do not correct straight-pipe discharges within ten months of notification to penalties of $500 per month for each month of subsequent noncompliance.

Citizens with contactor disputes should contact the Attorney General's Consumer Division.
