heavy equipment and vehicles involving oil changes, hydraulic system drain <br /> down, solvent and de-greasing cleaning operations, fuel tank drain down and <br /> removal, and other activities which may result in discharge or spillage of <br /> pollutants to the ground or into stormwater runoff must be conducted using spill <br /> prevention measures, such as drip pans. Contaminated surfaces shall be cleaned <br /> immediately following any discharge or spill incident. Emergency repairs may be <br /> performed on-site using temporary plastic placed beneath and, if raining, over the <br /> vehicle. <br /> 10. Control De-Watering: <br /> Not applicable <br /> 11. Maintain BMPs: <br /> All temporary and permanent erosion and sediment control BMPs shall be <br /> maintained and repaired as needed to assure continued performance of their <br /> intended function. Maintenance and repair shall be conducted in accordance with <br /> BMP specifications. All temporary erosion and sediment control BMPs shall be <br /> removed within 30 days after final site stabilization is achieved or after the <br /> temporary BMPs are no longer needed. Trapped sediment shall be removed or <br /> stabilized on site. Disturbed soil resulting from removal of BMPs or vegetation <br /> shall be permanently stabilized. <br /> 12. Manage the Project: <br /> The site will be managed by the owner. <br /> Protect On-site Stormwater Management BMPs for Runoff from Roofs and <br /> Other Hard Surfaces. On-site stormwater management BMPs used for runoff from <br /> roofs and other hard surfaces include: roof downspout full infiltration or <br /> dispersion systems. The areas on the site to be used for these BMPs shall be <br /> protected from siltation and compaction during construction by sequencing the <br /> construction in a fashion to install these BMPs at the latter part of the construction <br /> grading operations, by excluding equipment from the BMPS and the associated <br /> areas by using the erosion and sedimentation control BMPs listed above. <br /> Additional requirements for protecting these BMPs during the construction <br /> process, testing functionality, and restoring functionality are needed at the final <br /> stage of the construction process and are included in the specific BMP sections in <br /> Volume V of this manual. Relevant BMP (Per the January 2016 Snohomish <br /> County Drainage Manual Volume II - Construction Stormwater Pollution <br /> Prevention—page 19.) <br /> MR3 WATER POLLUTION SOURCE CONTROL FOR NEW <br /> DEVELOPMENT <br /> The site is an established site and no water pollution source control is required. <br /> rye, <br />
