Subsurface sewage treatment systems disclosure requirements modified, and rulemaking required.

HF 1888 modifies disclosure requirements for subsurface sewage treatment systems (septic systems) in Minnesota and mandates new rulemaking by the Pollution Control Agency. The bill directly affects homeowners selling properties with septic systems, local governments enforcing regulations, and septic system professionals (installers, inspectors, maintainers). Key provisions require the agency to develop new rules about what information must be disclosed to buyers regarding a system's condition and compliance, repealing outdated disclosure language in current law. The bill does not set specific disclosure rules but requires the agency to create them through formal rulemaking.
