At industrial sites, we need to be concerned about chemical spills that contain toxic substances, smoke stacks that spew emissions and uncovered or unprotected outdoor storage or waste areas that can contribute pollutants to storm water runoff. Best management practices include:
Wash vehicles or equipment in wash bays hooked up to the sanitary sewer. Don't wash off detergents, oils and greases into streets or storm rains.
Divert rainfall runoff from fueling islands by building a canopy or cover over them.
Waste and processed water of any type must be discharged to the sanitary sewer.
Hosing off pavements wash pollutants into storm drains that lead straight to the river.
