The bill amends Minnesota Statutes 2024, section 115.55, by adding a new subdivision that establishes guidelines for determining compliance of subsurface sewage treatment systems. It mandates that agencies, local governments, and inspectors utilize the "best evidence" available regarding the presence of sewage contaminants in groundwater. This "best evidence" includes results from various testing methods that are less than two years old, prioritizing laboratory measurements, continuous depth measurements, and historical groundwater data, among others.

Additionally, the bill requires that when property owners or lessees provide results from these testing methods, they must be accepted as valid evidence of compliance. Furthermore, it stipulates that individuals must be informed of their rights under this new subdivision at least 90 days prior to any notice of noncompliance being issued. This legislation aims to enhance the accuracy and reliability of compliance assessments for subsurface sewage treatment systems, ensuring that the most current data is utilized in decision-making processes.
