Retail Gasoline _.,utiets <br /> This Fact Sheet provides Best Management <br /> Practices (BMPs) that are recommended for facilities <br /> that provide vehicle fueling services. <br /> Potential Pollutant Sources <br /> The following activities are potential sources of <br /> pollutants: <br /> • Fueling <br /> Air/water supplying areas <br /> . Dumpster and trash can areas <br /> Pollutants may include: <br /> • Heavy metals (copper, lead, nickel, and zinc) <br /> . Hydrocarbons (oil and grease, PAHs) <br /> Toxic chemicals (benzene, toluene, xylene) <br /> Trash <br /> Pollution Prevention <br /> Using pollution prevention measures may reduce or eliminate the need for other more costly or <br /> complicated procedures. <br /> The following pollution prevention principles apply to most facilities: <br /> • Use alternative, safer, non-toxic, and/or recycled products. <br /> Reduce storm water flow across the site and redirect flows away from storm drains, <br /> gutters, and streets. <br /> Reduce the use of water and/or use dry methods (i.e., sweeping). <br /> Provide on-going employee training. <br /> Best Management Practices and Procedures <br /> GENERAL <br /> ► If water is being used for cleaning outdoor areas, contain the wash water. A permit is <br /> required to dispose of wash water in the sanitary sewer (call the City of Stockton, <br /> Environmental Control Office at 937-8740 for disposal approval). Never discharge wash <br /> water into storm drains, gutters or streets. <br /> ► Maintain facility and move/cover activities/materials to prevent contact with storm water. <br /> P. Inspect and clean leaks and drips routinely. <br /> ► Label drains within the facility boundary to indicate whether they flow to an oil/water <br /> separator, directly to the sewer, or to a storm drain. <br /> ► Inspect/clean, storm drain inlets within the facility boundary before October 1 each year. <br /> FUELING <br /> ► Maintain fuel dispensing areas using dry cleanup methods such as sweeping for removal of <br /> litter and debris, or use of rags and absorbents for leaks and spills. <br /> ► Fueling areas should never be washed down unless the wash water is collected and <br /> contained. A permit is required to discharge waste water in the sanitary sewer. Do not <br /> discharge waste to the sanitary sewer until contacting the local sewer authority (call the City <br /> of Stockton, Environmental Control Office at 937-8740 for disposal approval) to determine if <br /> pretreatment is required. <br /> Retail Gasoline Outlets t <br />
