3.0 BEST MANAGEMENT PRACTICES <br />The BMPs are measures used to reduce or mitigate storm water pollution from industrial <br />activities. BMPs are a broad class of measures and may include processes, procedures, <br />schedules of activities, and prohibition of practices. Specific measures followed at this <br />facility are discussed below. <br />3.1 Housekeeping <br />General good housekeeping measures are employed to minimize the potential for a release <br />to the storm water drainage system. Garbage containers are emptied on a weekly basis by <br />Allied Waste Management Inc. Garbage cans with cleanup wastes are disposed of <br />separately. <br />The site employs a vacuum sweeping company to remove dust and accumulated sediment <br />on a monthly basis. The oil water separators are inspected quarterly and a vacuum disposal <br />company is contracted to dispose of accumulated oil on a quarterly basis. <br />3.2 Preventative Maintenance <br />All catch basins are cleaned when the depth of debris accumulates and the debris surface <br />will be maintained at least 6 inches below the outlet pipe. The secondary containment vault <br />is inspected daily, to insure that the rubber cover is being effective at restricting water <br />accumulation, and to insure that at least 2,500-gallon secondary containment volume is <br />available for an emergency release. The operation and maintenance manual for the oil stop <br />valve is closed and all stormwater from the site is being collected in the secondary <br />containment vault. Water is being disposed off -site by Marine Vacuum Service who's <br />number is (206) 762-0240. <br />3.3 Spill Prevention and Emergency Cleanup <br />Employees are trained in hazardous materials management and storage requirements. Spill <br />response equipment and materials are readily accessible. A notification system has been <br />established and a copy of the SWPPP is current and available at Nelson's main facility as <br />identified in Table 4. <br />Table 4 - Emergency Response Contacts <br />Incident Agency/Response Subcontractor Telephone Number <br />Fire City of Everett Fire Dept. 911 <br />Release to Sewer City of Everett Public Utilities (425) 257-8882 <br />US Ecology (800) 883-4672 <br />Release to Soil Washington Department of Ecology (425) 649-7000 <br />Groundwater State Emergency Response Commission 911 <br />Uncontrolled Release Slotta Design and Consulting (206) 459-5775 <br />
