Sensitive Receptors The WQCF is situated on approximately 22 acres in the northeastern section of a 210-acre site that is dominated by agricultural fields where WQCF-treated effluent is land applied for irrigation; no sensitive receptors are located immediately adjacent to the treatment plant. Commercial development is located directly north of the WQCF along Yosemite Avenue, and the"Stadium Center" shopping center is approximately 2,000 feet to the south on State Route(SR) 120.A"Big League Dreams"recreational facility is located approximately 600 feet to the south. Residential housing is located beyond the agricultural lands surrounding the WQCF site along Yosemite Avenue, McKinley Avenue,Airport Way, and SR 120. The nearest residences are approximately 600 feet northeast of the central plant facilities. The next closest point of similar residential development is roughly 1,300 feet to the northwest. There are seven schools located within 2 miles of the WQCF. The nearest school is approximately 0.75 mile west of the WQCF. Two hospitals are situated approximately 3,500 feet to the northeast, and a children's clinic is approximately 1.5 miles northeast of the site. SR 120,which forms the southern site boundary, is located approximately 3,200 feet from central plant facilities,while the Union Pacific Railroad line,which forms the western site boundary, is located approximately 1,200 feet from central plant facilities. As discussed above,no sensitive receptors would be adversely affected by the proposed wastewater collection system and recycled water distribution system because wastewater collection system and recycled water distribution system pipelines would be buried underground and would not convey hazardous materials. 4.6.2 ENVIRONMENTAL IMPACTS ANALYSIS METHODOLOGY The following reports documenting potential hazardous conditions at the project site were reviewed for this analysis: ► plans for the project; ► available literature, including documents published by federal, state, county, and city agencies; and ► applicable elements from the City general plan. In addition to reviewing the above reports,EDAW searched EPA's Envirofacts website to identify any new hazardous materials sites in the project area. Project activities were evaluated against the hazardous materials information gathered from the above sources to determine whether any risks to public health and safety or other conflicts would occur. EDAW also searched DTSC's online EnviroStor Database, and found that the WQCF site is not listed in regulatory agency databases as a known hazardous materials contamination site, and is not included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5. Therefore,this issue is not evaluated further in this DEIR. THRESHOLDS OF SIGNIFICANCE For purposes of this analysis,the following applicable thresholds of significance have been used to determine whether implementing the proposed project would result in a significant impact. These thresholds of significance are based on the State CEQA Guidelines. The proposed project would result in significant hazardous materials impacts if it would: ► create a significant hazard to the public or the environment through the routine transport,use,or disposal of hazardous materials; ► create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment; EDAW Manteca WQCF and Collection System Master Plans EIR Hazards and Hazardous Materials 4.6-10 City of Manteca
