North County Recycling Center and Sanitary Landfill Permit Revision Project Final Initial Study/Mitigated Negative Declaration · San Joaquin County | May 2025 33 ENVIRONMENTAL SETTING The project site is located in an unincorporated area of San Joaquin County, east of Lodi. Like other areas located in seismically active California, the project area is susceptible to strong ground shaking during an earthquake. However, the project site is not located within an earthquake fault zone (California Department of Conservation 2024). Also, slopes within the landfill are maintained at a 3:1 horizontal to vertical ratio to lower the probability of landslides induced by seismic events. When the landfill was originally constructed, the native soil was extensively disturbed or replaced with imported material. However, solid waste facilities are subject to Title 27 of the California Code of Regulations, which sets the parameters for the siting, design, and construction of landfills. These standards are meant to ensure that the facilities can withstand seismic events without damage to the structures which control surface drainage and erosion. DISCUSSION OF IMPACTS a-i) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving: Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? No Impact No active faults have been identified in the immediate vicinity of the project site. The project site is not within any Earthquake Fault Zone designated by the state under the Alquist-Priolo Earthquake Fault Zoning Act (California Department of Conservation 2024). Operation of the proposed project would be similar to existing conditions and would not cause substantial effects associated with rupture of a known earthquake fault. Therefore, the project would not cause substantial effects including the risk of loss, injury, or death associated with rupture of a known earthquake fault. There would be no impact related to adverse effects from the rupture of a known earthquake fault. a-ii) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving: Strong seismic ground shaking? No Impact Project operation would not result in any substantial effects related to strong seismic ground shaking because project activities are limited to an increase in waste accepted by the landfill; no site modifications are proposed. Therefore, the proposed project would not result in substantial effects associated with strong seismic ground shaking and no impact would occur. a-iii, a-iv) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving: Seismic-related ground failure, including liquefaction? Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving: Landslides? No Impact The project site is not located within a known earthquake fault zone or designated landslide zone. Project activities are operational and do not involve site expansion. Furthermore, as mentioned in the environmental setting, existing slopes within the landfill are maintained at a 3:1 ratio, lowering the potential of landslide damage. Also, the project site is not located in a
