Come see this presentation to see examples of BMPs that are designed to prevent spilled fuel from entering infiltration and other BMPs. This presentation will also include design guidelines based on reported spill data from California retail fueling sites.

The essence of Scott's presentation:
New and redeveloped service stations are often required to install infiltration BMPs. Usually these infiltration BMPs are not designed to prevent the infiltration of fuel in the event of a spill. In this paper we examine self-reported spill data, collected by the California Office of Emergency Management, between the years 2006 and 2014, to determine the frequency and magnitude of fuel spills at service stations. From this information we show that reported fuel spills greater than 1 gallon occur at a frequency of 1 every 3.7 facility-years and fuel spills greater than 5 gallons occur at a frequency of 1 every 8.5 facility-years. Spills larger than 100 gallons occur at a rate of 1 every 136 facility-years. These results suggest that spills occur at a sufficient frequency to require the inclusion of additional BMP design elements at service stations to prevent spilled fuel from contaminating infiltration BMPs.
