Seethe Erosion <br />Control Plan exhibit at the end of this section for a plan view of the proposed TESC BMPs. <br />Below is a discussion of each of the thirteen Construction Stormwater Pollution Prevention Elements and a summary <br />of applicable BMPs. Design, installation, and maintenance of any specific BMP should be carried out in accordance <br />with the DOE Manual and any further instructions detailed in the construction plans. Included in Appendix 1 of this <br />report are the DOE Manual specifications, tables, and figures for each BMP identified in this report. <br />Element 1- Preserve Vegetation/Mark Clearing Limits <br />Work limits will be identified in the field from the construction plans. Paint lines, silt fence, high -visibility fence <br />and/or stakes will be used to delineate the limits of construction. Existing vegetation should be preserved where <br />possible to limit the area of exposed soils. <br />Applicable BMPs: BMP C101: Preserving Natural Vegetation <br />BMP C233: Silt Fence <br />Element 2- Establish Construction Access <br />Construction vehicles will access the site from two construction entrances off of Railway Avenue on the east side of <br />the site. Construction entrances shall be built per plan. A wheel wash shall be used if the construction entrances <br />are not effective in preventing tracking of sediment offsite. Any debris generated as a result of construction activity <br />on paved surfaces will be swept clean to prevent tracking onto public roads. <br />Applicable BMPs: <br />BMP C105: Stabilized Construction Entrance / Exit <br />BMP C106: Wheel Wash <br />BMP C107: Construction Road/Parking Area Stabilization <br />Element 3- Control Flow Rates <br />The proposed project is flow control exempt. See the Permanent Stormwater Control Plan for the determination of <br />this exemption. <br />Applicable BMPs: N/A <br />Element 4- Install Sediment Controls <br />Catch Basin Inserts (CBI) will be used by the contractor to minimize sediment entering the existing catch basins. If <br />any catch basins or inserts become filled with sediment or debris, it must be cleaned in such a manner as to prevent <br />material from entering the stormwater drainage system. Sweeping of paved surfaces will also help to prevent <br />sediment from entering the existing system. Silt fencing will reduce the sediment load of runoff. <br />Applicable BMPs: BMP C220: Storm Drain Inlet Protection <br />BMP C233: Silt Fence <br />SITTS & HILL ENGINEERS, INC. 8 <br />TACOMA, WASHINGTON <br />
