GeoTracker database, and to describe the site remediation. The GeoTracker database is the State Water Resources Control Board's management system for sites that impact, or have the potential to impact, water quality in California, with emphasis on groundwater. The database contains both current and historic records of spill and cleanup sites and is not the Cortese List compiled pursuant to Government Code Section 65962.5 (the link to which is provided in Response 12). The Geotracker database identifies that the site had leakage from underground piping in 1986 and went through remediation until cleanup was determined by the RWQCB to be "Completed" and the RWQCB case was "Closed" in 2010. In addition, the site would not be put on the Cortese List for remedial contamination. As described in Section 5.7, Hazards and Hazardous Materials, of the Draft EIR, the Project site has undergone extensive testing related to hazardous substances through preparation of a Phase I Environmental Site Assessment in 2018, a Phase II Environmental Site Assessment in 2018, and a Limited Phase II Subsurface Investigation Report in 2019, which are provided as Appendix F of the Draft EIR. These investigations determined that the Project site contains approximately 900 cubic yards of contaminated soil that would require excavation and disposal as part of excavation and grading activities. This includes approximately, 850 cubic yards of TPH contaminated soils (above residential screening levels) and 80 cubic yards of TPH-(diesel) contaminated soils. These contaminated soils are part of the existing condition and would be remediated during Project excavation and grading activities as required by DTSC, California Integrated Waste Management Board, RWQCB, OCFA, and the Orange County Health Care Agency (OCHCA) for residential uses. Thus, with compliance with existing regulations as implemented through the City's permitting process and Mitigation Measure HAZ-1, the Project would safely remove the existing hazardous materials and improve the environment of the Project site. These cleanup activities that would occur as part of the Project would not result in the site being included on the Cortese List. Comment 14: This comment states that the EIR fails to disclose material information about the Project site, and that the public and decision makers are required to dig the appendices of the EIR in order to find out basic information about the Project, and asserts that this is a violation of CEQA. The comment further asserts that the Draft EIR: • Does not disclose that the Project site is contaminated with hazardous materials at levels that exceed residential human health screening levels. • Does not disclose the impact the existing contamination could have on human health of construction workers or future residents of the Property. • Does not mention or describe previous hazardous materials remediation efforts at the Project site. • Does not disclose that the Project will need to re -open its formerly closed case in order to further remediate existing contamination such that the site would meet residential contamination standards. Response 14: This comment is inaccurate. The Draft and Final EIRs describe the various subsurface investigations that were conducted on the site to identify potential areas of contamination. As described in Section 5.7, Hazards and Hazardous Materials, of the Draft EIR, the Project site has undergone extensive testing related to hazardous substances through preparation of a Phase I Environmental Site Assessment, Phase II Environmental Site Assessment, and a Limited Phase II Subsurface Investigation that are summarized on page 5.7-9 of the Draft EIR. The Draft EIR describes the location of the former underground storage tanks (USTs) and the estimated volume of existing soil that is contaminated with petroleum hydrocarbons (TPH) above residential screening levels. In addition, the Draft EIR describes that 75C-112
