Acceptance of best evidence requirement to determine subsurface sewage treatment system compliance

This bill requires Minnesota agencies and inspectors to accept specific, recent evidence when checking if subsurface sewage treatment systems are working properly. It mandates that officials use the most reliable data available from the last two years, such as lab-tested groundwater results or measurements of the water table depth, to make compliance decisions. The law also ensures that property owners receive at least 90 days' notice of their rights before being told their system is non-compliant. Directly affecting local governments and system owners, the measure aims to standardize how sewage system inspections are conducted across the state.
