The Boeing Everett Environmental Health and Safety Process Instruction (EHSPI)-130, which <br /> defines the procedures and responsibility, accountability, and authority (RAA's) for complying <br /> with the Construction Stormwater General Permit, is included in Appendix B. <br /> 2.1 The 12 Elements <br /> 2.1.1 Element 1 : Preserve Vegetation / Mark Clearing Limits <br /> Describe the methods (signs, fences, etc,) you will use to protect those areas that should not be <br /> disturbed. <br /> Describe natural features identified and how each will be protected during construction. Trees <br /> that are to be preserved, as well as all sensitive areas and their buffers, shall be clearly <br /> delineated, both in the field and on the plans. <br /> Describe how natural vegetation and native topsoil will be preserved. <br /> List and describe BMPs: <br /> To protect adjacent roads and the parking lot, enhance public safety and to reduce the area of <br /> soil exposed to construction, the limits of the site will be fenced in. Marking serves to limit <br /> construction traffic and to control track out. The jurisdictional ditch that cannot be touched at <br /> this time will be fenced around with a silt fence and a 5' wide berm will be placed along the <br /> south and west sides of the ditch to keep water and silt from entering the pond. The pond at the <br /> south west corner off the site will get a silt fence to keep silt from discharging the site into the <br /> storm line. The BMPs relevant to marking the clearing limits that will be applied for this project <br /> include <br /> • High Visibility Plastic or Metal Fence (BMP C103) <br /> • Silt Fence (BMP C233) <br /> Installation Schedules: <br /> The site perimeter fence and silt fence will be the first activity to take place approximately from <br /> May 22nd 2015 — May 291h 2015. <br /> Inspection and Maintenance plan: <br /> The construction fence will be maintained around the perimeter of the site. Water filled barriers <br /> will be used because they can be moved at any time as the project progresses. This fence <br /> prevents pedestrian access to the site from the south, east, and west faces. The silt fence will <br /> be inspected, maintained, and repaired as needed to make sure it is working properly and has <br /> not been damaged. BMP's will also be checked within 24 hours of a rain event. <br /> Responsible Staff: <br /> Steve Roetemeyer with MiclMountain Contractors will be the onsite CESCL to maintain. <br /> Page 18 <br />
