i Draft Supplemental Environmental Impact Report Page IV.F-38 • Forward Inc. Landfill 2018 Expansion Project Mitigation Measure F.B. The project shall comply with the SJMSCP mitigation requirements i for the conversion of row and field crop lands (SJCOG 2000). Under the SJMSCP(2000), each • acre of Swainson's hawk habitat (i.e., Agricultural Habitat Lands) converted to non-open space uses would be mitigated by the establishment of 1 acre of Row and Field Crop/Riparian i Preserve (a 1:1 mitigation ratio). This measure would apply to the 8.6 acres of land to be developed in the southern portion of the property. This would reduce this impact to a less than • significant level. Impact F.9. Increase in Existing levels of Night Lighting. Night lighting is not expected to , increase, as all project components would be within the boundaries of the existing active landfill • facility area. This is a less than significant impact and no mitigation is required. • Impact F.10. Use of Rodenticides in the Capped Areas of Landfill Could Result in Adverse Impacts to Wildlife. As part of permits issued to landfills, rodent control is important to • maintaining the integrity of the landfill cap and liner to prevent leaching or seepage. Rodent • control is conducted through the application of rodenticides that is regulated through the , Department of Agriculture. Application of rodenticides could adversely affect predator species, such as raptors and carnivores that feed on rodents on the site. When poisoned rodents are depredated, they can deliver significant doses to the predator. Raptors that eat small mammals • in urban and agricultural areas are at risk of secondary poisoning from anticoagulant • rodenticides, which can cause internal hemorrhaging and mortality. Some anticoagulants take several days to work(e.g., brodifacoum) even with lethal doses, allowing rodents to forage and be exposed to raptor predation before dying. As a participant in the SJMSCP, Forward . proposes to incorporate SJMSCP guidelines developed to minimize potential effects of • rodenticides to giant garter snake,burrowing owl, and Swainsori s hawk(USEPA 2000, Appendix A of the SJMSCP). However, this is still considered a potentially significant impact. i Mitigation Measure H.10. Rodenticides and methods of application used at the landfill shall be reviewed by a qualified biologist approved by the SJMSP TAC, to determine if they reflect the • most effective and safe methods for controlling rodents. That biologist shall make recommendations for improvement if needed. This mitigation measure would reduce these potential impacts to less than significant levels because rodenticide use would be strictly monitored and limited to TAC-approved methods. i Impact F.11. Project Effects on Wildlife Corridors. All proposed project components would be within the boundaries of the existing landfill. Therefore, the proposed project would not • create a new barrier to terrestrial wildlife movement. Additionally, the relocation of the South Branch of South Littlejohn Creek to the south of the landfill would maintain a potential movement corridor for terrestrial and aquatic wildlife. Therefore, this impact would be less than significant and no mitigation is required. • Impact F.12. Project Effects on San Joaquin Kit Fox. Based on the lack of suitable habitat and any records of the species within the study area and surrounding region, kit foxes are not expected to occur on the site. Additionally, the SJMSCP does not require precontruction surveys for kit fox in the project area (i.e., Central Zone). Therefore, the project would have no • i
