83. Prior to the commencement of any clearing, grading, or excavation, the applicant shall submit a copy of the State Water Resources Control Board Notice of Intent (NOI) for coverage under the State Construction Storm Water General Permit. 84. A Storm Water Pollution Prevention Plan (SWPPP) shall be developed and implemented for each site covered by the general permit. A SWPPP shall include Best Management Practices (BMPs) designed to reduce potential impacts to surface water quality through the construction and life of the project. A SWPPP shall be prepared such that, when properly implemented, will reduce or eliminate impacts to surface water quality from all phases of the project. Required elements of the SWPPP include the following: a) Construction storm water management controls shall be implemented which include practices to minimize the contact of construction material, equipment, and maintenance supplies (e.g., fuels, lubricants, paints, solvents, adhesives) with storm water. The SWPPP shall specify properly-designed centralized storage areas that keep these materials out of the rain. It shall also include a monitoring program by the construction site supervisor. b) Best Management Practices (BMPs) shall be implemented to reduce erosion of exposed soil and may include, but not be limited to, soil stabilization controls, watering for dust control, perimeter silt fencing, placement of hay bales, and sediment basins. The potential for erosion is generally increased if grading is performed during the rainy season as disturbed soil can be exposed to rainfall and storm runoff. If grading must be conducted during the rainy season, the primary BMPs selected shall focus on erosion control to keep sediment on the slopes. End-of-pipe sediment control measures (e.g., basins and traps) shall be used only as secondary measures. If hydroseeding is selected as the primary soil stabilization method, then slopes shall be seeded by September 1 to October 1. Entry and egress from the construction site shall be carefully controlled to minimize off-site tracking of sediment. Vehicle and equipment wash-down facilities shall be designed to be accessible and functional both during dry and wet conditions. Geotechnical and Soil-Gas Report 85. The applicant shall comply with the recommendations of the geotechnical report prepared by Terrasearch, Inc. dated July 7, 1999. The applicant's geotechnical consultant shall review and approve all foundation, retaining wall, and drainage geotechnical aspects of the final development plans to ensure that the recommendations have been properly incorporated into the development. The consultant shall certify by writing on the plans or as otherwise acceptable to the Director of Building Inspection that the final development plan is in conformance with the geotechnical report approved with the project.
