See the attached A-48 Required Operation BMPs attached. Hazardous materials are not anticipated to be stored on the site. Hazardous materials expected to be dispensed on the site would include diesel fuel and gasoline utilized to refuel heavy equipment. Project construction will conform to the requirements of RMC 4-4-030C7 Construction Standards - 7. Construction Debris: Construction debris, such as concrete, lumber, etc., must be removed and not buried on site. Stormwater Pollution Prevention Manual • King County82 A-48 Mobile Fueling of Vehicles and Heavy Equipment Mobile fueling, also known as eet fueling, wet fueling, or wet hosing, is the practice of lling fuel tanks of vehicles or equipment by fuel tank trucks, tank trailers, and trucks with accessory fueling tanks that are driven to the yards or sites where the vehicles to be fueled are located. Required Operational BMPs: • Obtain approval from the local re department. Comply with local and Washington State re codes. • The driver/operator must be present and constantly observe the fuel transfer to ensure the implementation of the following procedures at all fuel transfer locations: » To the extent practical, locate the point of fueling at least 25 feet from the nearest stormdrain or drainage ditch, or inside an impervious containment with a volumetric holding capacity equal to or greater than 110 percent of the fueling tank volume, or covering the stormdrain to prevent discharge of spilled or leaked fuel. Covers are not required for storm drains that convey the inow to a spill control separator approved by the local jurisdiction and the re department; » Place a leak–proof drip pan or an absorbent pad under each fueling location prior to and during all dispensing operations. The pan or the absorbent pad must have a capacity of at least 5 gallons. There is no need to report spills retained in the drip pan or the pad; » Manage the handling and operation of fuel transfer hoses and nozzle, drip pan(s), and absorbent pads as needed to prevent spills/leaks of fuel from reaching the ground, stormdrain, or surface waters; » Do not extend fueling hoses across a trac lane without uorescent trac cones, or equivalent devices, conspicuously placed to block all trac from crossing the fuel hose; » Remove the ll nozzle and cease lling the tank when the automatic shut–o valve engages. Do not lock automatic shuto fueling nozzles in the open position; » Do not “top o” the fuel tanks; and » Do not use dispersants or soap to clean up spills or sheens. • Develop and follow a mobile fueling plan that includes the required operational BMPs and spill response procedures. • The responsible manager shall: » Sign and date the mobile fueling plan; » Distribute procedures to the operators; and » Update and retain them in the organization les • Immediately notify the local re department (911) and Ecology in the event of any spill entering surface or ground waters. Establish a “call down list” to ensure the rapid and proper notication of management and government ocials should any signicant amount of product be lost o–site. Keep the list in a protected but readily accessible location in the mobile fueling truck. The “call down list” should also pre–identify spill response contractors available in the area to ensure the rapid removal of signicant product spillage into the environment. Stormwater Pollution Prevention Manual • King County 83 • Train the driver/operator upon hiring, and annually thereafter, on proper fueling procedures, spill prevention, cleanup measures, and emergency procedures. Make all employees aware of the signicant liability associated with fuel spills. • The driver/operator of the fueling vehicle must have: » A current copy of the mobile fueling plan; » Adequate ashlights or other mobile lighting to view fuel ll openings with poor accessibility; and » Two–way communication with the operator’s home base. • Maintain a minimum of the following spill clean–up materials in all fueling vehicles, that are readily available for use: » Non–water absorbents capable of absorbing at least 15 gallons of diesel fuel; » A storm drain plug or cover kit » Two, ve–gallon buckets with lids or sealable disposal bags; » A non–spark generating shovel; and » For fuel tankers and trailers with fueling tanks greater than 100 gallons, a non–water absorbent containment boom, minimum 10 feet in length with a 12–gallon minimum absorbent capacity. • Use automatic shuto nozzles for dispensing the fuel. Replace automatic shut–o nozzles as recommended by the manufacturer. • Maintain fueling equipment, particularly hoses and nozzles. • Use an adequate lighting system at the lling point.
