PROJECT #2: FORMER ARCO GAS STATION <br />Page 35 <br />August 1, 2022 <br />It is our assumption that the City of Santa Ana is planning to purchase the subject property (Site) and <br />utilize it for residential redevelopment. We researched the State Water Resources Control Board's <br />Database of Environmental Records — GeoTracker, with the Site address to evaluate the Site and its <br />surrounding conditions. A -Tech identified that the Site is a former Arco Gas Station #5147 with a closed <br />cleanup case (GeoTracker Global ID of T0605900621). The Site obtained closure as of March 23, <br />2022, from the Santa Ana Regional Water Quality Control Board (Water Board). Since 2005 until <br />closure in March 2022, numerous environmental investigations, remediations, and litigations were <br />conducted related to release of petroleum products from historical gas station operations. A -Tech has <br />reviewed these reports and provided a summary of the reports and regulatory activities in Table 5. <br />For the purpose of this fee proposal and as it is described in the RFP, A -Tech assumes that the City of <br />Santa Ana has retained services of A -Tech for 1) conducting a Phase I ESA of the property, 2) the Phase <br />I ESA will lead to a Phase II ESA in connection with UST removal activities, and 3) a comprehensive <br />hazardous material survey of gas station structures and the shops building. <br />A Phase I ESA will be prepared in accordance <br />with the updated ASTM 1527-21 and as <br />described in Section Ld. The Phase I ESA for Deliverables: <br />this project will be in accordance with the ✓ Phase I ESA Report <br />Schedule of Halladay Property project as it is <br />presented in Table 3. Because of the historical <br />operations at the Site and the potential leakage from the USTs and gas station activities, it is more than <br />likely that the Phase I ESA conclusion will warrant conducting a Phase II ESA for this property. <br />The detailed cost estimate for the Phase I ESA of Former Arco Gas Station is provided <br />in Table D of the sealed fee proposal envelope. <br />ow A -Tech Consulting, Inc. <br />
