MN SF3969

Creates certification program for biodigester and water reclamation systems that separately treat greywater and blackwater for residential wastewater management in Minnesota.

Requires manufacturers to submit third-party testing documentation to the Pollution Control Agency commissioner certifying systems meet state standards for discharge or potable water, with manufacturers reimbursing up to $4,000 in review costs.

Mandates only trained and certified persons may install, operate, maintain, and monitor systems, with annual monitoring reports submitted to the commissioner, health commissioner, and local regulatory authorities.

Exempts biodigester and water reclamation systems from Minnesota Rules chapter 4714 requirements until January 1, 2029, with all provisions in the bill expiring on that date.

Establishes system treatment standards including separate handling of blackwater (not for reuse), greywater meeting health risk limits for indoor reuse or water quality standards for outdoor discharge, and blackwater residuals meeting federal biosolids regulations.
