The IS also found that the proposed project would not interfere with an emergency response plan or emergency evacuation plan.An Emergency Operations Plan was developed for whole MHMP area which addresses all forms of emergency response,the responsible parties,and communication protocols.The proposed project would be required to be consistent with this plan. Lastly,the IS found that the proposed — project would not expose people or structures to significant risks involving wildland fires because the project site is not located on or near lands associated with wildlands. Therefore, in accordance with Section 15063(b)(1)(C)of the CEQA Guidelines,the potential for the proposed project to conflict with _ the SJMSCP,interference with an emergency response plan, exposure to wildland fires are not evaluated further in this EIR. See the IS(Appendix D of this Draft EIR) for further discussion. IMPACT Public Health and Safety—Possible Exposure to Pre-Existing Hazardous Materials During 4.9.1 Construction. The proposed project could unearth or otherwise disturb pre-existing hazardous materials at the project site during construction,potentially exposing construction workers or others to hazardous _ materials.A significant impact would occur. Exposure to Potential Hazardous Materials Sites Development of the proposed project would involve grading, excavation,dewatering, demolition, and other construction activities at the College Park site and off-site infrastructure locations.The project site has a history of agriculture use, including the use of pesticides,herbicides, fuels,and other hazardous materials. While the Phase I ESAs did not identify listed hazardous material sites specifically related to agricultural activity,the ESAs did indicate that at least one of the pesticides used at the project site (paraquat)has a half-life of more than 1,000 days and is typically highly persistent in surface soils.The — ESAs also documented violations of the Clean Water Act associated with the discharge of animal waste to surface waters by the Lucky J Dairy which required legal action by the state to correct,and the presence of ASTs,USTs,septic systems,refuse piles,waste ponds,rusted 55-gallon drums, electrical transformers possibly containing PCBs,and other potential sources of contamination at the project site. Finally,the ESAs documented a December 4, 2003 incident directly southeast of the project site where a tractor accidentally struck the 18-inch Chevron crude oil pipeline that bisects the project site,releasing _ approximately 21,000 gallons of crude oil.Yet undiscovered soil or groundwater contamination associated with these or other undocumented potential contaminant sources may occur at the project site. The unearthing or disturbance of the above could result in potential exposure of construction workers and _ others to hazardous materials.This would represent a significant impact. The field reconnaissance conducted for the Phase I ESAs did not include Grant Line Village because project-level approvals are not being sought at this time as part of the specific plan,and did not include the Machado property(Figure 34),including the Lucky J Dairy because permission to access the site for reconnaissance was not granted by the property owner. Therefore,these areas may contain yet undocumented potential hazardous materials-related contamination sources(Phase I field reconnaissance — of these locations will be required before development).The unearthing or disturbance of any such potential sources at these sites could result in potential exposure of construction workers and others to hazardous materials.This would represent a significant impact. _ The field reconnaissance conducted for the Grant Line Road expansion area identified household garbage and roadside litter along Grant Line Road.The Phase I ESA conducted for the Grant Line Road expansion area recommends that debris and litter be collected for appropriate disposal. During collection of the debris and litter there is the possibility of encountering hazardous materials or stained soil.Therefore, activities associated with removing the debris and litter could result in potential exposure of workers and others to hazardous materials. This would represent a significant impact. EDAW College Park at Mountain House Specific Plan III Draft EIR Public Health and Safety 4.9-28 San Joaquin County
