Draft Supplemental Environmental Impact Report Page IV.F-39 Forward Inc. Landfill 2018 Expansion Project 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. Mitigation Measure F.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. 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 Littlejohns 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 preconstruction surveys for kit fox in the project area (i.e., Central Zone). Therefore,the project would have no ' impact to this species and no mitigation is required. S
