Properly Design Fueling Area
  • The fueling area must be covered with an overhanging roof structure or canopy. The canopy’s minimum dimensions must be equal or greater than the area within the grade break. The canopy must not drain onto the fuel dispensing area and the canopy downspouts must be routed to prevent drainage across the fueling area.

Properly Design Repair/ Maintenance Bays
  • Repair/maintenance bays must be indoors and designed to avoid stormwater run-on or contact with stormwater runoff.
  • Bay drainage system must capture all washwater, leaks and spills. Connect drains to a sump for collection and disposal. Direct connection of the repair/maintenance bays sump to the storm drain system is prohibited. Obtain an Industrial Waste Discharge Permit for connection to the sanitary sewer system.
Properly Design Vehicle/Equipment Wash Areas
