Problem Solution
Vehicle and equipment maintenance – oils, fluids, detergents, and greases can wash into streets or storm drains.                                                  Wash vehicles or equipment in wash bays hooked up to the sanitary sewer.
Fueling Islands – over filling and splashes can spill onto pavement. Divert rainfall runoff from fueling islands by building a canopy or cover over them.
Barrels containing potentially hazardous liquids can leak or spill onto the ground. In compliance with Fire Code, any barrels containing potentially hazardous liquids should be in a sealed container, stored inside a building or under cover, and propped up on pallets with secondary containment in case of a spill. Call your Fire Department for code specifics.
Discharge of wastewater to the ground or storm drains is prohibited. Waste and processed water of any type must be discharged to the sanitary sewer.
Hosing off pavements washes pollutants into storm drains leading straight to streams and rivers SWEEP!
Chemical spills that contain toxic substances can contribute pollutants to stormwater runoff. Be sure to know spill cleanup procedures. Have cleanup materials nearby with a spill prevention plan prepared and procedures known by all employees. Three quarters of all spills of hazardous chemicals can be attributed to human error. Best Management Practices (BMPs) are aimed at preventing spills and environmental incidents by making employees and management aware of the issues.
