5 – Effects Found Not To Be Significant Draft Environmental Impact Report February 2021 14800 W. Schulte Road Logistics Center 5-10 Fire Hazard The Project site is not located within a Very High Fire Hazard Severity Zone (FHSZ) according to the Local Responsibility and State Responsibility Area (SRA) maps by the California Department of Forestry and Fire Protection (CAL FIRE). CAL FIRE has designated areas south and southwest of the Project site as being within a Moderate FHSZ within a Local Responsibility Area (CAL FIRE 2020). In addition, some undeveloped hillside areas in the Diablo Mountains south of I -580, approximately 3.7 miles southwest of the Project site, are designated as being within a High FHSZ within an SRA (CAL FIRE 2020). These ratings do not extend to the Project site, and the Delta Mendota Canal separates the Project site from these areas to the south, which could function as a firebreak in the event of a wildfire, further lessening the potential for wildfire to affect the Project site. Therefore, impacts associated with wildland fires would be less than significant. 5.5 Hydrology and Water Quality Degradation to Surface or Groundwater Quality Construction of the Project would include earthwork activities that could potentially result in erosion and sedimentation, which could subsequently degrade downstream receiving waters and violate water quality standards. Stormwater runoff during the construction phase may contain silt and debris, resulting in a short-term increase in the sediment load of the municipal storm drain system. Substances such as oils, fuels, paints, and solvents may be inadvertently spilled on the Project site and subsequently conveyed via stormwater to nearby drainages, watersheds, and groundwater. For stormwater discharges associated with construction activity in California, the State Water Resources Control Board (SWRCB) has adopted the General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities (Construction General Permit) to avoid and minimize water quality impacts attributable to such activities. The Construction General Permit applies to all projects in which construction activity disturbs 1 acre or more of soil. Construction activity subject to this permit includes clearing, grading, and disturbances to the ground, such as stockpiling and excavation. The Construction General Permit requires the development a nd implementation of a SWPPP, which would include and specify water quality BMPs designed to prevent pollutants from contacting stormwater and keep all products of erosion from moving off site into receiving waters. Routine inspection of all BMPs is required under the provisions of the Construction General Permit, and the SWPPP must be prepared and implemented by qualified individuals as defined by the SWRCB. Because land disturbance for Project construction activities would exceed 1 acre, the Project applicant would be required to obtain coverage under the Construction General Permit issued by the SWRCB prior to the start of construction within the Project site. Specifically, the Construction General Permit requires that the following be kept on site at all times: a copy of the Notice of Intent to Comply with Terms of the General Permit to Discharge Water Associated with Construction Activity; a waste discharge identification number issued by the SWRCB; a SWPPP and Monitoring Program Plan for the constructi on activity requiring the construction permit; and records of all inspections, compliance and non -compliance reports, evidence of self -inspection, and good housekeeping practices. The SWPPP requires the construction contractor to implement water quality BMPs to ensure that water quality standards are met and that stormwater runoff from the construction work areas do not cause degradation of water quality in receiving water bodies. The SWPPP must describe the type, location, and function of stormwater BMPs to
