Task 27 — Indoor Air and Ambient Air Quality Assessment Evaluate whether indoor air quality of existing buildings adjacent to the former Tiger Oil facility, including the Xochimilco Mexican Restaurant, Barber HQ, and 1 UP Games, has been adversely impacted by the HVOC-impacted groundwater at the Site. Task 28 — 2021 to 2022 Semiannual Groundwater Monitoring Continue conducting semiannual groundwater monitoring events at the Site to evaluate both the petroleum hydrocarbon- and HVOC-impacted groundwater and to support decision making regarding additional actions that may be needed to explore long-term monitored natural attenuation and achieve a satisfaction of consent decree. Task 29—Update Site Management Plan Update the draft Site Management Plan (SK8P)due bnthe confirmed finding cfthe HVDCaimpacted groundwater atthe Site. The purpose cf the SyNPiohoprovide guidance for future earthwork, construction, and operations on the Site to manage risks associated with residual contaminated soil and groundwater. The updated SMP will address future construction and operations on the Site that could encounter contaminated soil and groundwater such as excavation, utility trenching, and stormwater management.
