Stormwater Pollution Prevention for PRESSURE WASHING Keep our communities, creeks, lakes, and Puget Sound healthy. Special Considerations for Buildings: PCBs • Buildings built or renovated from about 1950 to 1979 had widespread use of PCBs (polychlorinated biphenyls). • PCBs may be present in caulking, grout, joint materials, paints, sealants, lubricants, roofing, metal coatings, and light ballasts. • PCBs are toxic and cancercausing chemicals. Wash Water Disposal • Wash water that contains solid waste and petroleum products must be filtered prior to disposal. LOCAL CONTACT INFORMATION AND LOGO HERE Hazardous Waste Disposal • Pressure washing can create hazardous waste that needs special disposal, including: » Dirty absorbent materials that may contain PCBs. » Rags or absorbent pads with gasoline, oils, grease, thinner, solvent, or organic chemicals. • Dispose of hazardous waste properly. » Option 1: Use a licensed waste hauler. » Option 2: Bring small quantities of accepted waste to a hazardous waste drop-off location. • Keep records of your hazardous waste disposal: who hauled it, how much was hauled, and when it was hauled.

Treat the Wastewater • Use filter fabric to filter the water. • Solid pieces of waste go into the garbage. BMPs for Washing to Best Management Practices (BMPs) • Sweep work areas to cleanup. • Cover or block nearby storm drains. • Do NOT direct or pour wash water into a storm drain. • DO manage wash water by one of these options: 1. Direct into a landscaped area to soak into the ground. 2. Discharge to the sanitary sewer (toilet or indoor sink) is okay if the water has only small amounts of grit or oil. The Problem • Wastewater from washing practices can contain toxic pollutants. • Pressure washing can release pollutants from surfaces due to the force of the water. • When not cleaned up properly, waste from washing can pollute stormwater runoff. • Storm drains flow to the nearest creek, lake, wetland, or Puget Sound. Only Rain Down the Drain • Regulations and laws about pressure washing can vary by location, and some jurisdictions strictly regulate pressure washing. • But they all have one thing in common: ONLY RAIN DOWN THE DRAIN. • Do NOT use soap or chemicals. • Wash water that contains soap (including biodegradable), chemicals, soil, or is untreated should NOT be dumped – these are pollutants and can kill fish. Sweep and use dry cleanup methods. Do NOT hose off the ground. » Storm drain grate covers » Ground cover tarps » Portable pump and hoses » Portable ground berm » Sand bags » Absorbent pads and socks/boom Stormwater Pollution Education Guide https://apps.ecology. wa.gov/publications/ documents/0710058.pdf DIY Wash Water Reclaim System youtube.com/watch ?v=cmdxslBDtFE BMPs for Washing and Steam Cleaning Vehicles / Equipment / Building Structures tinyurl.com/59ms2ck7 berm around shop catch basin covered missing containment berm missing ground cover
