2. Dumpsters shall be stored under cover,where feasible,with any necessary drains routed to the sanitary sewer. As an alternative,dumpsters shall be non-leaking and water-tight, with lids that prevent the entry of stormwater. Lids shall be kept closed when dumpsters are not being filled or emptied. 3. Dumpsters shall be kept in good condition without corrosion or leaky seams. Damaged or leaking containers shall be replaced. 4. If waste container drums are stored above ground,they shall be kept in an area such as a service bay. If drums are kept outside,they must be stored under cover to keep rainfall from reaching the drums. Storage of reactive, ignitable,or flammable liquids must comply with the Uniform Fire Code(R.2 in Section 4- 3). The following practices shall complement,not conflict,with current Uniform Fire Code requirements. 1. Containers shall be located in a designated area. 2. The designated area shall be paved, free of cracks and gaps, and completely impervious in order to contain leaks and spills. 3. For liquid wastes, tanks shall be surrounded by dikes,berms,or curbs. The dike, berm,or curb shall be of sufficient height to provide a volume that is the greater of either 10%of the total enclosed tank volume or 110%of the volume contained in the largest tank. 4. The designated area shall be covered. 5. The area inside the dike, berm or curb shall slope to a drain. If the material being stored is controlled by the Uniform Fire Code, or is used oil or Dangerous Waste,the drain shall outlet to a dead-end sump. For all other liquids the drain shall be tied to the sanitary sewer, if available. A discharge permit from the City's Industrial Pretreatment Program will be required. Otherwise,process treatment or a dead-end sump shall be used subject to other permit requirements. The drain must have positive control(for example,a locked drainage valve or plug)to prevent release of contaminated liquids. 6. If the business is using rolling containers(for example, dumpsters)that are picked up directly by a collection truck,the dike, berm or curb can be modified to facilitate moving the dumpster. 7. Where material is temporarily stored in containers,a temporary,portable containment system can be used, in lieu of the above system. 8. If a container is to be located in an area where firearms may be discharged,the container should be encapsulated with concrete(or equivalent). 9. Containers mounted for direct removal of a liquid chemical for use by employees shall be placed inside a containment area as described above. In addition,a drip pan shall be used at all times below the container outlet. 10. Drums stored in an area where unauthorized persons may gain access must be secured in a manner that prevents any unauthorized use. 11. If the material is a Dangerous Waste,the business owner shall comply with any additional Department of Ecology requirements(see R.3 in Section 4-3)not presented above. 12. An employee trained in emergency spill cleanup procedures shall be present when Dangerous Wastes, liquid chemicals,or other wastes are loaded or unloaded(see BMP S1.80). ✓j 4-2-11
