SECTION 02270 <br />EROSION CONTROL <br />PART 1 - GENERAL <br />1.01 WORK INCLUDED <br />A. The work of this section consists of furnishing all necessary labor, equipment, material and <br />transportation necessary to provide temporary and permanent erosion and sediment control <br />as required by appropriate government agency permits, the plans and as noted in this <br />specification. The Contractor shall execute and provide all necessary BMP's, monitoring <br />and maintenance as outlined in the Stormwater Pollution Prevention Plan (SWPPP) <br />developed for this project. <br />PART 2 - PRODUCTS <br />N/A <br />PART 3 - EXECUTION <br />3.01 INSTALLATION <br />A. Install temporary erosion and sediment control items prior to clearing and commencing <br />earthwork or as soon as practical as site work progresses. <br />3.02 BEST MANAGEMENT PRACTICES (BMP's) <br />A. Stabilization of Denuded Areas: No disturbed area may be denuded for more than thm <br />calendar days (or 72 hours for sloped banks of 3:1 or greater), excluding travel ways, <br />unless otherwise authorized by the Owner's Engineer. During construction, denuded areas <br />shall be covered by mulches such as straw, hay, filter, seed and mulch, sod or some other <br />permanent vegetation. Within sixty (60) calendar days after final grade is established on <br />any portion of a project site, that portion of the site shall be provided with established <br />permanent soil stabilization measures per the construction drawings, whether by <br />impervious surface or landscaping. <br />B. Protection and Stabilization of Stockpiles: Fill material stockpiles shall be protected at all <br />times by on-site drainage controls which prevent erosion of the stockpiled material. <br />Control of dust from such stockpiles may be required, depending upon their location and <br />the expected length of time the stockpiles will be present. In no case shall an unstabilized <br />stockpile remain after thirty 00) calendar days. <br />C. Protection of Existing Storm Sewer Systems: During construction, all storm sewer inlets <br />shall be protected by approved sediment traps such as secured hay bales, sod, stone, etc., <br />which shall be maintained and modified as required by construction progress, and which <br />must be approved by the Owner's Engineer, <br />D. Sediment Trapping Measures: Sediment basins and traps, perimeter berms, filter fences, <br />berms, sediment barriers (hay bales), vegetative buffers and other measures intended to <br />trap sediment and/or prevent the transportation of sediment onto adjacent properties, or <br />02270 - Erosion Control <br />02270 -1 <br />
