Pollution Prevention Opportunities Try to minimize spills that could be picked up when yopu hose down or when it rains. Change oil, coolant or other vehicle fluids indoors on impervious surfaces, using drip pans to catch small spills and drips. Have a spill response policy in place and make sure everyone knows what to do to keep the spill from moving off your property. If you have a septic system, be sure that the bathroom wastes are not mixed with shop wastewater.

This will catch spills during connection and disconnection. Require the fuel transporter and used oil hauler to immediately clean up any spills from tank refilling operations.
