Based on review of the State Environmental Policy Act(SEPA) <br /> checklist associated with this Project,the Department of Ecology(Ecology) has the following <br /> comments: <br /> All waste streams generated as a result of this project must be properly designated(see WAC <br /> 173-303-070), a process of determining whether a waste must be managed as dangerous waste <br /> and what the major hazards are. Inadequate designation creates risks and results in improper <br /> disposal of dangerous wastes. Gas station decommissioning activities may generate materials <br /> that designate as hazardous or dangerous waste, including but not limited to: gasoline <br /> contaminated fuel filters, hoses,nozzles, spill clean-up debris, or tank sludges. <br /> In Washington,we use the term"dangerous waste"while the federal rules use the term <br /> "hazardous waste." Washington's Dangerous Waste Regulations are based on the federal <br /> Resource Conservation and Recovery Act(RCRA); however, dangerous waste includes more <br /> wastes than the federal definition. <br /> Please visit Ecology's website to find information on waste designation, generator status <br /> requirements, dangerous waste annual reporting, and additional information about the Dangerous <br /> Waste Regulations and how they might pertain to activities conducted on your site. <br /> See Ecology's "Dangerous Waste Guidance for Gas Stations" for more information: <br /> https://fortress.wa.gov/ecy/publicationsidocuments/1404011.pdf. <br /> Ecology's "Shop Guide for Dangerous Waste Management"may also be useful: <br /> https://fortress.wa.gov/ecy/publications/documents/0904015.pdf. _- <br /> 4 <br />
