North County Recycling Center and Sanitary Landfill Permit Revision Project Final Initial Study/Mitigated Negative Declaration · San Joaquin County | May 2025 50 resources in Eastern San Joaquin County (Eastern San Joaquin Groundwater Management Plan 2014). DISCUSSION OF IMPACTS a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? No Impact The project is limited to landfill operations and will remain subject to the SWPP discussed above, CCR 27 Section 20260, and CCR 27 Section 20220. Class III landfills, such as the North County Landfill, are not allowed to accept hazardous waste materials. Furthermore, per CCR 27 Section 20260, “new Class III and existing Class II-2 landfills shall be sited where soil characteristics, distance from waste to ground water, and other factors will ensure no impairment of beneficial uses of surface water or of ground water beneath or adjacent to the landfill.” The landfill will remain subject to the SWPPP and the BMPs contained during project operation. Due to continued compliance with the current SWPPPP and state regulations, there would be no impact related to water quality. b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? Less-than-Significant Impact Project activities are limited to operational modifications and will not require any construction activity; thus, no new impervious surfaces will be introduced to the project site. Operation of the project would require use of water for irrigation and landfill activities utilizing existing water lines within the project area, however this would not be a substantial increase over what is currently being used. Therefore, the project would result in a less-than-significant impact on groundwater supplies. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: (i) result in substantial erosion or siltation on- or off-site; (ii) substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site; (iii) create or contribute runoff water that would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted runoff; or (iv) impede or redirect flood flows? Less-than-Significant Impact The project would not involve any construction work or site modifications and therefore would not cause substantial erosion or siltation. In addition, as described in Impact a), the project has an existing SWPPP to prevent excessive runoff and erosion and siltation during project operation. Project operation would not result in a substantial increase in impervious surface area which would cause an increase in surface runoff. The impact would be less than significant. d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation?
