r Iiai Study—LID Annexation hazard for people residing or working in the project area? f) For a project within the vicinity of a private airstrip, would the ❑ ❑ ❑ 0 project result in a safety hazard for people residing or working in the project area? g) Impair implementation of or physically interfere with an adopted ❑ ❑ ❑ 0 emergency response plan or emergency evacuation plan? h) Expose people or structures to a significant risk of loss, injury or ❑ ❑ ❑ E death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? During all phases of development associated with River Islands,the storage, use,and transport of hazardous materials would likely occur during construction activities on the project site;the same would be true of LID's facility construction.The River Islands EIR and MMRP required the handling of hazardous materials at the site be in compliance with local, state,and federal regulations. Therefore, impacts related to creation of significant hazards to the public through routine transport, storage, use, disposal, and risk of upset would not occur. Additionally, impacts associated with past agricultural and farming operations in the project area could have resulted in contamination of soil and/or groundwater in some locations. Demolition, excavation,and construction activities could result in the exposure of construction workers to hazardous materials, including asbestos,petroleum hydrocarbons, pesticides, herbicides,and fertilizers.As a result,the City has required that before demolition of any structures associated with past and current farming operations(e.g.,buildings,ASTs,USTs),the project applicant shall investigate the extent to which soil and groundwater has been contaminated from these operations. This investigation would include, as necessary,analysis of soil and/or groundwater samples taken at or near the potential contamination sites.If the results indicate that contamination exists at levels above regulatory action standards,then the San Joaquin County Environmental Health Division(SJCEHD)shall be notified and the site shall be remediated in accordance with recommendations made SJCEHD, Regional Water Quality Control Board, Department of Toxic Substance Control, or other appropriate federal, state, or local regulatory agencies. The above mitigation measure lowers the impact to a level of insignificance.The Project shall incorporate this measure in its construction activities,(e.g.pole line construction, underground trenching,etc.). The Project would not involve any additional significant effects in this issue area and would not require any additional mitigation measures. For the provision of sewer and water services, hazards and hazardous materials impacts were analyzed in the Lathrop Water, Wastewater and Recycled Water Master Plan EIR (Master Plan EIR), River Islands EIR and for sewer and recycled water, the Phase I Expansion of Water Recycling Plant No. 1 EIR and LAFCO's LID Formation Initial Study/MND. All of these documents are incorporated by reference. Any impacts associated with these services would be mitigated by the mitigation measures identified in these previous documents and no additional analysis is necessary. Copies of the documents are available in the San Joaquin County Community Development Department Office. The proposed project does not involve substantial changes to the Project which will require major revisions of the prior environmental documents due to the involvement of new or substantially more severe environmental impacts because the LID formation and the LID's provision of services previously were evaluated in the prior environmental documents. Further, there are no substantial changes with 40
