1 . Recycle materials,such as oils,solvents,and wood waste,to the maximum extent prac- ticable. INote: Evidence of stormwater contamination by oils and grease can include the presence of visible sheen,color,or turbidity in the runoff,or present or historical operational problems at the facility. I Operators can use simple pH tests,for example with litmus or pH paper.These tests can screen for high or low pH levels(anything outside a 6.5-8.5 range)due to contamination in stormwater. I S455 BMPs for Spill Prevention and Cleanup Description of Pollutant Sources: Spills and leaks can damage public infrastructure, interfere I with sewage treatment,and cause a threat to human health or the environment. Spills are often pre- ventable if appropriate chemical and waste handling techniques are practiced effectively and the spill response plan is immediately implemented.Additional spill control requirements may be required Ibased on the specific activity occurring on site. Applicable BMPs: ISpill Prevention I . Clearly label or mark all containers that contain potential pollutants. . Store and transport liquid materials in appropriate containers with tight-fitting lids. . Place drip pans underneath all containers,fittings,valves, and where materials are likely to spill or leak. I . Use tarpaulins,ground cloths,or drip pans in areas where materials are mixed,carried,and applied to capture any spilled materials. . Train employees on the safe techniques for handling materials used on the site and to check Ifor leaks and spills. Spill Plan I . Develop and implement a spill plan and update it annually or whenever there is a change in activities or staff responsible for spill cleanup. Post a written summary of the plan at areas with I a high potential for spills, such as loading docks, product storage areas,waste storage areas, and near a phone.The spill plan may need to be posted at multiple locations. Describe the facility, including the owner's name, address, and telephone number;the nature of the facility Iactivity;and the general types of chemicals used at the facility. . Designate spill response employees to be on-site during business activities. Provide a current I list of the names and telephone numbers(home and office)of designated spill response employees who are responsible for implementing the spill plan. . Provide a site plan showing the locations of storage areas for chemicals, inlets/catch basins, Ispill kits and other relevant infrastructure or materials information. . Describe the emergency cleanup and disposal procedures. Note the location of all spill kits in I I 2019 Stormwater Management Manual for Western Washington Volume IV-Chapter 1 -Page 501
