1 <br />1 <br />PENSKE TRUCK LEASING EVERETT ONSITE IMPROVEMENTS <br />CONSTRUCTION STORMWATER POLLUTION PREVENTION PLAN <br />Element 9- Control Pollutants <br />Sitts & Hill Engineers, Inc. <br />Job Number 17,710 <br />All material to be removed/demolished will be disposed of at an approved off -site location. Fueling and lubrication <br />of construction vehicles and other motorized equipment will be performed using spill prevention and control <br />measures. Construction equipment will be inspected daily as part of regular maintenance activities. Any leaks or <br />other sources of contamination will be repaired immediately. Spillage or other discharges of pollutants will be <br />reported within 24 hours. Also, the contractor will maintain any materials necessary for rapid cleanup of spills. <br />BMP'S TO CONSIDER FOR ALL ACTIVITIES <br />Suggested BMPs include: <br />1) Avoid the activity or reduce its occurrence. <br />2) Sweep an indoor or outdoor work area instead of hosing it into the storm drain or other drainage <br />conveyance. <br />3) Store items inside if possible. <br />4) Use less material. Don't buy or use more material than you really need. <br />5) Use the less toxic materials available. Investigate the use of materials that are less toxic than what you <br />use now. Perhaps a caustic type detergent or a solvent could be replaced with a more environmentally <br />friendly product. <br />6) Maintain vegetated areas near activity locations. <br />7) Locate activities as far as possible from surface drainage paths. Activities located as far as possible from <br />known drainage paths, ditches and drains will be less likely to pollute, since it will take longer for <br />material to reach drainage features. <br />8) Keep storm drainage systems clean. <br />9) Be an advocate for stormwater pollution prevention. Help friends, partners and business associates find <br />ways to reduce stormwater pollution in their activities. <br />Applicable BMPs: BMP C151: Concrete Handling <br />g <br />BMP C152: Sawcutting and Surfacing Pollution Prevention <br />' BMP C153: Material Delivery, Storage and Containment <br />BMP C154: Concrete Washout Area <br />' Element 10- Control De -Watering <br />De -watering water must be treated prior to discharge. Treatment method and discharge location must be approved <br />by the City. <br />Applicable BMPs: N/A <br />Element 11- Maintain BMPs <br />All erosion and sediment control BMPs will be maintained and repaired as needed during construction. Installed <br />BMPs will be inspected weekly (unless otherwise specified) or after any large storm event for stability and <br />functionality. Deficiencies will be corrected in such a way as to prevent sediment from entering the stormwater <br />drainage system. <br />Applicable BMPs: BMP C150: Materials on Hand <br />BMP C160: Certified Erosion and Sediment Control Lead <br />SITTS & HILL ENGINEERS, INC. 10 <br />TACOMA, WASHINGTON <br />
