Auto wreckers that <br />dismantle automobiles for scrap are Sector N: Scrap recycling and waste recycling facilities. <br />Activities at automotive salvage yards that can impact stormwater include vehicle dismantling; vehicle, <br />equipment, and parts washing; vehicle and parts storage; fueling stations; equipment maintenance and storage; <br />above ground storage tanks; and illicit connections to the storm sewer. Common pollutants are solvents, heavy <br />metals, fuels, oil and grease. <br />Pollution prevention ideas <br />Minnesota’s industrial stormwater permit requires a written Stormwater Pollution Prevention Plan (SWPPP). <br />Use the SWPPP to assess potential sources of pollutants at your facility and then identify practices that will <br />minimize these pollutants in runoff from the site. This fact sheet lists pollution prevention (P2) practices that can <br />be incorporated into your facility’s SWPPP. <br />Keep in mind that pollution prevention is best achieved by qualifying for the No Exposure exclusion. No <br />Exposure means that rain, snow, and runoff do not contact pollutant-containing materials or activities. Your <br />facility can apply for the No Exposure certification as soon as you qualify, even if you already have the full <br />permit. For more information visit the MPCA’s No Exposure web page at <br />http://www.pca.state.mn.us/noexposure. <br />General strategies <br />• Keep materials and activities indoors as much as possible. Confine outdoor materials and activities to <br />designated areas that are covered, have an impervious concrete surface, or have a system (such as berms <br />or dikes) to prevent run-on of stormwater and runoff of pollutants. <br />• Regularly clean up areas used for dismantling, washing, storage, fueling and maintenance using dry <br />methods such as sweeping, squeegee and dust pan, reusable socks, vacuums, and as a last resort, use <br />loose granular absorbents. <br />• Plug drains or use diversion devices to prevent spilled materials and liquids (including wash water) from <br />entering floor drains, sewer connections or storm drains. <br />Dismantling and vehicle maintenance <br />• Inspect vehicles for leaks as soon as possible after they arrive. Immediately take care of vehicles that <br />arrive with leaks. <br />• Drain all fluids from vehicles when they arrive, including oil filters. Drain indoors when possible or on a <br />dedicated pad. Empty drip pans and containers daily rather than leaving them full and open around the <br />shop. <br />• Segregate the fluids and properly store or dispose of them. Mark all vehicles that have been fully drained. <br />Minnesota Pollution Control Agency <br />651-296-6300 | 800-657-3864 | TTY 651-282-5332 or 800-657-3864 <br />April 2015 | p-p2s8-03 <br />Available in alternative formats <br />
