The bill establishes a voluntary certification program for commercial salt applicators in Minnesota, aimed at promoting best management practices for snow and ice removal while protecting water quality. The program, overseen by the commissioner of the Pollution Control Agency, includes training and certification for individuals who apply deicer, with a focus on environmentally friendly practices. Certified commercial applicators will be recognized as "water-friendly applicators" upon successful completion of the training and examination. The bill also mandates that these applicators maintain detailed records of their practices and report the types and amounts of deicers used annually.

Additionally, the bill limits the liability of certified commercial applicators and property owners for damages resulting from snow and ice accumulation, provided that best management practices were followed. However, liability remains if gross negligence or intentional harm occurs. The bill includes provisions for record-keeping, penalties for non-compliance, and clarifies that municipal liability is unaffected. The certification program is set to expire on August 1, 2030, and will take effect on August 1, 2023.
