6.Other Statutory Considerations — Mitigation Measure Measure 6.7: Implement Mitigation Measures 4.8.1 a,4.8.1 b,4.8.2, and 4.8.3 to mitigate the project's incremental contribution to groundwater supply and quality impacts. Impact Significance After Mitigation: With implementation of Mitigation Measures 4.8.1 a,4.8.lb, and 4.8.1c,the project's impacts would be mitigated to a less-than- significant level and therefore,the incremental contribution to cumulative impacts is not cumulatively considerable and the cumulative impact is less than significant. Surface Water Impact 6.8: The project under Mining Option 2(mining out Hospital Creek and constructing a berm to form a large detention basin)could contribute to the cumulative reduction of flows to the San Joaquin River. Cumulative impacts would be significant. — Hospital Creek,Lone Tree Creek, and Ingram Creek combine downstream of the project site and enter the San Joaquin River near Vernalis. The flow contribution provided by Hospital Creek — represents approximately 50 percent of the total flows provided to the San Joaquin River by these three creeks. Therefore, if the project is approved under Mining Option 2, it would be a significant cumulative impact. — Mitigation Measure Measure 6.8: Implement Mitigation Measure 4.8.6. Impact Significance After Mitigation: With implementation of Mitigation Measure 4.8.6,the project's incremental contribution to surface water impacts would not be cumulatively considerable,and the cumulative impact would be less than significant. However, if Mitigation Measure 4.8.6 is not implemented and Mining Plan Option 2 is identified as the preferred approach to mining adjacent to Hospital Creek,then the impacts to hydrology,as described above, would remain significant and the project's incremental contribution to cumulative conditions would be significant. Biological Resources Impact 6.9: Cumulative impacts would be associated with increased disturbance to potential special-status species due to increased noise,loss of agricultural land and potential _ habitat,increased traffic along roadways which could potentially increase mortality of wildlife.The project's contribution to cumulative impacts to biological resources is potentially significant. The potential for wetlands exists on the project site, and potential habitat for several special status species has been identified for the project area. The special,status species include the San Joaquin kit fox,burrowing owl,and raptors. Mitigation measures have been provided for the project that would reduce potential impacts to wetlands and special status species.
