This video discusses the Best Management Practices (BMPs) in preventing storm water pollution for municipal employees who keep streets, parking lots and storm drain systems clean. Two of BMPs that are discussed are Material Management and Parking Lot and Street Cleaning. Large amounts of storm water runoff from rain and snow are common to streets and parking lots. Small leaks from vehicles can cause water pollution over time. That’s why MS4 employees have to know the correct protocol when street cleaning and replacing lines in the streets. Debris can get caught in the storm system, but with the proper cleaning, handling, and disposing storm water pollution can be minimized.
