Risk management measures currently in place by PG&E and Chevron, and adherence to MHMP MMP j and Delta College EIR mitigation measures requiring preparation of a Pipeline Safety Plan,coordination of project construction activities with PG&E and Chevron within 500 feet of their pipelines,remediation of any existing contamination, and mapping of the pipelines, would together minimize the potential for 1 leaks,ruptures,and other incidents involving on-site natural gas and crude oil pipelines.However, because an incident along the pipelines may still occur and habitable residential structures,parks,and open space are proposed in the proximity of the pipelines,a significant impact could occur. For an evaluation of potential project impacts on the PG&E/Chevron pipelines,see Section 4.5,"Public Utilities." S 1 Mitigation Measure 4.9-5: Public Health and Safety—Exposure to Pipeline Hazards.The following measures shall be implemented by the College Park developers: • No habitable residential structures(i.e., homes, apartments, granny flats, garages converted to living quarters,patio rooms, sun rooms)shall be permitted within 68 feet of the PG&E-Chevron pipeline that bisects the College Park site and contains Pipelines L401,L002,and CSDF 0499.Alternatively, no habitable residential structures as defined above shall be permitted within 68 feet of the nearest pipeline in the PG&E easement.Outdoor structures such as pools, fences,patios,and decks could be allowed within the no build zone, since occupancy would be less than 100%. Garages would be permitted as long as documentation accompanies the sale or rental documents for the residence prohibiting conversion of the garage to a habitable use(spare bedroom, game room,etc.). • Public disclosure of the hazard posed by the Pipelines Loo 1,L002,and CSDF 0499 shall be provided in the purchase and rental agreements for all habitable residential structures to be located within 249 feet of the PG&E/Chevron easement,and shall appear in all subsequent purchase and rental agreements associated with these structures. Implementation of the above mitigation measure would reduce exposure to pipeline hazards to a less- than-significant level. IMPACT Public Health and Safety—Exposure to Electromagnetic Fields. The proposed project would comply 4.9.6 with CDE school setback requirements from electrical transmission lines. While the project would result in _ development of residential uses in close proximity to electrical transmission lines,project compliance with the requirements of the MHMP and MHMP MMP would avoid significant adverse EMF-related health effects. A less•than•signfficant impact would occur _ The College Park project site is bisected by the Rio Oso-Tesla 230-kVA electrical transmission lines which are in the 75-foot wide PG&E easement.The proposed project would include the development of sensitive land uses(schools,residences)in relatively close proximity to the easement(Figure 3-613). 1 School buildings at the two proposed K-8 locations would each be set back from the easement by approximately 250 feet which is greater than the 150-foot setback required by CDE. The balance of the -� school sites, including the 2.5-acre play fields associated with each school would be set back 150 feet from the easement, so these fields would also comply with the CDE 150-foot setback requirement. Therefore, school children associated at the two proposed K-8 schools would not be exposed to adverse health effects from the EMFs emitted by the transmission lines,and a less-than-significant impact would occur. Under the proposed project,residential uses would be developed on either side of the Rio Oso-Tesla Transmission Line easement for much of the easement length.However,in accordance with the Specific EDAW College Park at Mountain House Specific Plan III Draft EIR Public Health and Safety 4.9-38 San Joaquin County
