2. Staging areas for vehicle maintenance activities during construction must be specified. These areas must be well away from all drainage courses. (SEPA Water, Plant and Animal and Land and Shoreline Use Policies) 3. Application of fungicides, herbicides, insecticides, and fertilizers is prohibited on all sites from January through April when soils are frequently saturated and storm events generate substantial runoff. (SEPA Water, Plant and Animal and Land and Shoreline Use Policies) 4. All storm drains must be stenciled with language similar to the following: "Dump No Waste, Drains to (Stream/Wetland/Groundwater)." This reminder is typically spray-painted on to the ground adjacent to the catch basin with the use of a stencil. The treatment needs to be repeated, approximately annually, when the paint wears off. The developer/owner may either perform the stenciling, or give permission for volunteer groups to enter onto the property and perform the stenciling. (SEPA Water, Plant and Animal, and Land and Shoreline Use Policies) 5. During construction activities, all spills must be contained and removed in such manner as to prevent their entering the waters and soils of the state. Cleanup of spills shall take precedence over other work on-site. (SEPA Water, Plant and Animal, and Land and Shoreline Use Policies) 6. Any new airplane fueling stations shall: • Minimize the potential for aviation fuel spills to enter the stormwater drainage system, by implementing source control options such as the following. The detailed design shall be reviewed and approved by the Responsible Official and Engineering and Public Services Director. • install new coalescing plate separator to serve surface runoff from new fueling stalls; • install a stormwater cut-off trench by the airplane wing fueling ports for new fueling stalls; and • install piping valving and an automated control system to divert dry weather runoff to a holding tank for periodic pump-out. Alternatively undertake a technical analysis and develop a plan that provides equal or better protection of the surfacewaters. (SEPA Water, Plant and Animal, and Land and Shoreline Use Policies) 7. For any new airplane fueling stations, the following measures shall be implemented after review by the Responsible Official and Engineering and Public Services Director. • Provide an ongoing employee training program to minimize the number of accidental fuel spill incidences. • Provide a spill control plan to control spills when they occur. (SEPA Water, Plant and Animal, and Land and Shoreline Use Policies) 8. Airplane Washing Areas: Any new airplane washing or de-icing areas shall be hydrologically isolated from the rest of the site and wash water from the area must drain to the sanitary sewer after being routed through a baffle-type oil/water separator designed to City standards. When not being used for washing or de-icing, the stormwater from these areas is discharged into the storm water system. An industrial pretreatment permit from the City's Public Works Department will be required for connection to the sanitary sewer. (SEPA Water, Plant and Animal, and Land and Shoreline Use Policies) 30
