This section covers Work necessary for minimizing erosion and preventing <br />the discharge of sediment during and after construction and land disturbing <br />activities. The Work shall include the furnishing of all labor, materials, tools, <br />and equipment to perform the Work and services necessary as herein specified <br />and as indicated on Drawings. This shall include installation, maintenance, <br />and final removal of all temporary soil erosion and sediment control measures. <br />B. The minimum areas requiring soil erosion and sediment control best <br />management practices (BMPs) are areas of land disturbance (from grading, <br />excavation, filling, and other land disturbing activities) and those shown in the <br />Stormwater Pollution Prevention Plan (SWPPP). The right is reserved to <br />modify use, location and quantities of soil erosion and sediment control BMPs <br />based on activities of the contractor. <br />C. Contractor shall provide an erosion and sedimentation control specialist <br />(ESCS) responsible for the implementation, maintenance and oversight of all <br />erosion and sedimentation control activities, including submittals, SWPPP <br />(and subsequent TESC Plan) development and implementation, dust control <br />measures, emergency activities, repairs and removal of temporary controls in <br />accordance with Washington’s Construction Stormwater Program, including <br />the 2019 Stormwater Manual for Eastern Washington. <br />D. Contractor shall be responsible for phasing Work in areas allocated for their <br />exclusive use during Project, including proposed stockpile areas, to restrict <br />sediment transport. This will include installation of temporary erosion control <br />devices, ditches, or other BMPs. <br />E. Sediment transport and erosion from working/temporary stockpiles shall be <br />controlled and restricted from moving beyond immediate stockpile area by <br />implementing the BMPs identified in the approved SWPPP. Additionally, <br />contractor shall implement the dust control BMP measures. Contractor shall <br />keep these erosion and sediment control BMPs in operational condition by <br />regular cleaning, regrading, and maintenance. Stockpiles remaining in place <br />longer than 14 calendar days shall be considered permanent stockpiles for <br />purposes of erosion and sediment control.
