This bill proposes the addition of permeable synthetic turf as a recognized best management practice for controlling stormwater runoff in Minnesota. It mandates that the commissioner of the Pollution Control Agency include guidelines for the installation of permeable synthetic turf in the Minnesota Stormwater Manual. The bill outlines specific requirements for the synthetic turf, including a minimum permeability rate of 25 inches of liquid per hour, compliance with flammability standards, and the absence of harmful substances such as PFAS. Additionally, it specifies that this turf should not be used in residential projects with rubber infill and must be manufactured to replicate natural turf for outdoor use.

Furthermore, the bill clarifies that indoor/outdoor carpeting designed for concrete surfaces, like patios, does not qualify as permeable synthetic turf and should not be utilized for stormwater management. This legislation aims to enhance stormwater management practices by incorporating innovative materials that can effectively mitigate runoff while adhering to environmental safety standards.
