12 implemented, the BMPs are to be installed and used per the CASQA BMP Fact Sheets, which are referenced in parenthesis and included in Appendix G: 1) Scheduling (EC-1) – A written plan shall be developed to sequence construction events with implementation of the erosion and sediment control BMPs while considering such factors as the local climate. 2) Hydraulic Mulch (EC-3) – Hydraulic mulch shall be used in rough graded areas and soil stockpiles that will remain exposed longer than 14 days. The hydraulic mulch shall include hydroseed as specified by the project landscape architect. The QSP shall coordinate with the grading contractor on scheduling of their work and applicability of the hydraulic mulch on exposed soil. It is critical that adequate time is given to allow the vegetation to establish prior to the rainy season. If hydraulic mulch cannot be established, geotextiles and mats may be used as a substitute. 3) Hydroseeding (EC-4) – Hydroseeding shall be used in combination with the hydrualic mulch (EC-3) discussed above. The following are primary sediment control measures that apply to this project and are to be implemented if needed as determined by the Erosion Control Plan, QSD, QSP or contractor. If implemented, the BMPs are to be installed and used per the CASQA BMP Fact Sheets, which are referenced in parenthesis and included in Appendix G: 4) Silt Fence (SE-1) – A silt fence shall be used around the perimeter of the project where water could leave the site per the erosion control plan (see Appendix N). It shall also be in place at all stockpiles located on site prior to any storms. 5) Fiber Rolls (SE-5) – Fiber rolls shall be used around the perimeter of the site and 15’ o/c on freshly graded slopes. The rolls shall be firmly trenched and staked into the soil to maintain their position. Fiber rolls shall also be in place prior to any rain events around stockpiles. 6) Street Sweeping and Vacuuming (SE-7) – In order to minimize sediments, metal pollutants, oil and grease going into the storm drain system; the contractor shall provide a pick up type street sweeper to be available at all times during construction. Visible sediment tracked into the public right away or existing pavements shall be cleaned prior to any rain events and within a maximum of 24 hours. The QSP shall inspect potential sediment tracking locations daily 7) Wind Erosion Control (WE-1) – Heavily traveled dirt roads on the construction site shall be sprinkled daily by a water truck for dust and sediment suppression. Additional areas of exposed soil shall be sprinkled during windy periods. Care should be taken to use a minimal quantity of water such that mud and runoff do not develop. 8) Stabilized Construction Entrance/Exit (TC-1) – The stabilized construction entrance consists of preparing pads of crushed stone to settle and separate sediment from equipment and vehicle tires. The construction entrance shall be constructed with CASQA Fact Sheet TC-1 and as shown in the Erosion Control Plan in Appendix N.
