6 Best Management Practices to Prevent Storm Water Runoff Pollution.

Storm water discharges are generated by runoff from land and impervious areas such as paved streets, parking lots, and building rooftops during rainfall and snow events that often contain pollutants in quantities that could adversely affect water quality. Most stormwater discharges are considered point sources and require coverage by an NPDES permit. The primary method to control storm water discharges is through the use of best management practices (BMPs).

Here are six Best Management Practices (BMP) for commercial locations to prevent Storm water runoff pollution.

1) Do not wash oils, soaps and greases into streets or storm drains. Wash vehicles or equipment in wash bays hooked up to the sanitary sewer.

2) Fueling islands should have a canopy or cover over them. This will prevent any fuel or oil on the island area from being washed in to the storm drain when it rains. Use dry absorbents to clean up any spills or leaks. Do not wash your fuel island areas down unless all water is recovered.

3) Barrels containing hazardous liquids should be in a sealed container, stored inside a building or under cover, and stored on secondary containment pallets in case of a leak.

4) Waste and processed water of any type must be discharged to the sanitary sewer.

5) Sweep, do not hose. Hosing off pavement washes pollutants into storm drains leading straight to local bodies of water.

6) Be sure to know spill cleanup procedures. Have spill kits nearby with a spill prevention plan prepared and procedures known by all employees.
