Tool Overview
Municipalities in Minnesota can use the Street Sweeping Phosphorus Credit Calculator to determine credits for phosphorus removal! Nearly 70% of Minnesota cities surveyed are already conducting some street sweeping activities. Why not optimize your efforts, claim reductions for your MS4, and quantify water quality benefits? The Calculator requires minimal data inputs to calculate load reductions.
