Auto Repair Shops <br />e <br />P. Sweep parking lots and areas around your facility instead of washing them down with <br />water. <br />► Send dirty rags to an industrial laundry. <br />- AUTOMOBILE SERVICING <br />► Conduct maintenance or repair work only in designated areas with spill containment. <br />Construct berms or intercept trenches at doorways to prevent the run-off of <br />uncontaminated storm water from adjacent areas as well as stormwater runoff. <br />■ Avoid working over asphalt and dirt floors — surfaces that absorb vehicle fluids. <br />► When removing or changing vehicle fluids, do so inside or under cover, if possible, to <br />prevent the run-on of storm water and the runoff of spills. <br />► Always use a drip pan under vehicles while unclipping hoses, unscrewing filters, or <br />removing other parts. <br />► Use a tarp, ground cloth, or drip pans beneath the vehicle or equipment to capture all spills <br />and drips if temporary work is being conducted outside. Collected drips and spills must be <br />disposed, reused, or recycled properly. <br />► Keep equipment clean - do not allow excessive build-up of oil and grease. <br />to. Monitor parked vehicles for leaks. Pans should be placed under any leaks to collect the <br />fluids for proper disposal or recycling. Drain oil and other fluids first if the vehicle or <br />equipment is to be stored outdoors. Do not allow leaking vehicles on-site. <br />► Avoid soldering over drip tanks. Sweep up drippings and recycle or dispose of as <br />hazardous waste. <br />► Sweep or use a vacuum to clean up dust and debris from scraping or bead blasting <br />radiators. <br />PARTS CLEANING <br />P. Clean vehicle parts without using liquid cleaners wherever possible to reduce waste. <br />► Steam cleaning and pressure'' washing may be used instead of solvent parts cleaning. The <br />wastewater generated from steam cleaning must be discharged to an on-site oil/water <br />separator that is connected to a sanitary sewer or blind sump. Never discharge <br />wastewater from steam cleaning, or engine/parts cleaning to streets, gutters, or storm <br />drains. <br />► Non -caustic detergents should be used instead of caustic cleaning agents, detergent - <br />based or water-based cleaning systems in place of organic solvent degreasers, and non - <br />chlorinated solvent in place of chlorinated organic solvents for parts cleaning. <br />► Designate specific areas or service bays for engine, parts, or radiator cleaning. Do not <br />wash or rinse parts outdoors. Keep water from flowing to storm drains, gutters, and <br />streets. <br />P. Use self-contained sinks and tanks when working with solvents. Keep sinks and tanks <br />covered when not in use. <br />► Rinse and drain parts over the solvent sink or tank. Use drip boards or pans to catch <br />excess solutions and divert them back to a sink or tank. <br />► Inspect degreasing solvent" sinks regularly for _leaks and make necessary repairs <br />immediately. <br />o. Allow parts to dry over the hot tank. If rinsing is required, rinse over the <br />`tank as well. <br />► Collect and reuse parts cleaning solvents and water used in flushing and testing radiators. <br />When reuse is no longer possible, these solutions may be hazardous wastes, and must be <br />disposed properly. <br />Discharging solvent rinse water into the sanitary sewer system is prohibited. <br />
