STORMWATER POLLUTION PREVENTION PLAN <br />South Parcel Fill Project <br />E of SR 529 8v S of 28th Place SE <br />Everett, WA 98201-4044 <br />PERMIT WAR 125060 <br />CalPortland Northwest, Inc. dba CalPortland owns property on Smith Island just north <br />of the town of Everett in Snohomish County, Washington. A portion of the property is <br />currently being developed by CalPortland to accommodate future planned uses of the <br />site. Development activities will include clearing existing brush, grading, landscaping, <br />and placement of 220,000 cubic yards of clean imported fill to raise the site elevation to <br />two-feet above the base flood elevation. <br />The General NPDES/stormwater discharge permit issued by the Department of Ecology <br />(General Permit) requires CalPortland to prepare a Stormwater Pollution Prevention <br />Plan (SWPPP) to minimize the possibility that stormwater that falls on the property <br />could be contaminated by operations at the site. The General Permit authorizes <br />discharges of stormwater associated with construction activity to waters of the state. <br />CalPortland's SWPPP outlines the measures taken to reduce, eliminate, and prevent <br />the pollution of stormwater through the application of best management practices <br />(BMPs) at the site. <br />A complete copy of the General Permit, this SWPPP, an Erosion and Sediment Control <br />Plan, and an Emergency Spill Response Plan are available at CalPortlands Everett <br />Ready M� facility as well as with Matt Hinck, Washington Division Environmental <br />Manager. <br />A. Site Layout <br />The attached site diagram identiiies the areas of operation at the site and those <br />activities that have the potential to contaminate stormwater (e.g. clearing/grading, <br />bulk materials storage, haul roads). There are no material processing operations, <br />vehicle maintenance, or waste treatment, storage, or disposal activities at the site. <br />Imported clean fill material is the only material stored in bulk at the project site. The <br />iill is delivered to the site by truck and stored temporarily in stockpiles around the site <br />until it is placed as part of site iill activities. Precipitation that falls on the stockpiled <br />iill material is rapidly absorbed or accumulates and drains from the site to Smith <br />Slough on the eastern project boundary. Silt fences and vegetated buffers help control <br />runoff and prevent stormwater pollution. <br />Fugitive dust is controlled by spraying the project site (haul roads especially) with <br />water as necessary. This water either evaporates or is rapidly absorbed into the <br />ground. <br />B. Best Management Practices <br />Yc� <br />
