North County Recycling Center and Sanitary Landfill Permit Revision Project Final Initial Study/Mitigated Negative Declaration · San Joaquin County | May 2025 27 boundary of the project area, which receives stormwater runoff from the landfill modules. Generally, water in the storm basin is retained for use on site, but the County may elect to discharge water to the mitigation area in the northern portion of the property. The storm basin enables pollutants to settle before the water is discharged to the mitigation area. The mitigation area is north of the project area and associated with South Paddy Creek. South Paddy Creek is a stream located to the north of the recycling center and discharges to Bear Creek. Bear Creek discharges into Disappointment Slough, a tributary to both the San Joaquin River and the California Delta. A narrow band of riparian habitat is present along the northern and western perimeter of the sedimentation basin. REGULATORY SETTING San Joaquin Multi-Species Habitat Conservation Plan The San Joaquin County Multi-Species Habitat Conservation and Open Space Plan provides a framework to manage open space preservation with the need to convert open space uses while protecting special status species and habitats. It covers the entirety of San Joaquin County and guides the management of plant, fish, and wildlife species, specifically those that are currently listed or may be listed in the future under the Federal Endangered Species Act (ESA) or the California Endangered Species Act (CESA). DISCUSSION OF IMPACTS a, b) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife (CDFW) or United States Fish and Wildlife Service (USFWS)? Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the CDFW or USFWS? No Impact The project is limited to operational changes and is located within an existing developed area. No special status plants or animals are present on the project site, nor does the site contain suitable habitat for special-status plants. While there may be areas outside of the project area that could support special status species, project activities are operational and will not expand the landfill’s footprint into these areas. Consequently, the project would not conflict with the County’s Multi-Species Habitat Conservation and Open Space Plan or the mitigation area north of the landfill. There would be no impact to any special status species, protected habitats, or conflicts with the County’s Habitat Conservation Plan. c, d) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? No Impact The project does not include any site modifications. Project activities are limited to an increase in solid waste acceptance within the landfill’s existing footprint. No wetlands or migratory
