"Retail Gasoline Outlet" means any facility engaged in selling gasoline and lubricating oils.


Prevent storm water pollutants of concern such as oil and grease, solvents, car battery acid, coolant and gasoline from entering into the storm water conveyance system.
Provide storm drain system Stenciling and Signage (only applicable if a catch basin is built on-site).
Properly Design Outdoor Material Storage Areas (if included).
  • Must be placed in an enclosure or bermed area (secondary containment) with minimum berm height of a half inch.
  • Must be paved to contain leaks and spills.
Properly Design Trash Storage Areas (if included).
  • Must be screened or walled to prevent off-site transport of trash.
  • Used lined bins or dumpsters to reduce leaking of liquid waste.
  • Pave trash storage areas with an impervious surface to mitigate spills.
Provide proof on ongoing BMP Maintenance (only applicable if a structural BMP is installed).
Design Standards for Structural or Treatment Control BMPs:
Post-construction Treatment Control BMPs are required to incorporate, at minimum, either a volumetric or flow based treatment control design standard or both, to mitigate (infiltrate, filter or treat) storm water runoff on site.


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.
  • The fueling area must be paved with smooth impervious surface (i.e. Portland cement concrete) that extends 6.5 feet (2.0 meters) minimum from the corner of each fuel dispenser. The use of asphalt concrete shall be prohibited.
  • The fuel dispensing area must have a 2% to 4% slope to prevent ponding, and must be separated from the rest of the site by a grade break that prevents run-on of stormwater.
Site and Roof Drainage
  • Site shall be graded to drain to single grating catch basins with filter inserts. The catch basin shall be in accordance with the City of Los Angeles Standard Plan S-355-0 with depth modified to accommodate drainage elevations. Minimum depth of catch basin insert shall be 24 inches.
  • Proof of ongoing catch basin inset maintenance shall be kept on site indicating the insert type, operator name, activity date and activity type.
