Document Description
The project involves approval of the 200 East Washington Boulevard Removal Action Workplan Removal Action Workplan (RAW) for the Washington Boulevard / Los Angeles Street Mixed-use Project (Site). Site assessments conducted between 2016 and 2019 identified the presence of lead in soil at the Site at concentrations above screening levels for commercial and industrial soils. In addition, volatile organic compounds (VOCs) have been identified in soil vapor underlying the Site in concentrations above California Department of Toxic Substances Control (DTSC) human health screening levels. The presence of these contaminants may impact future onsite occupants, existing offsite residents, and commercial workers. Therefore, the RAW was prepared to identify measures to mitigate potential human exposure to lead and VOCs present in the subsurface.
A Revised Supplemental Site Investigation prepared in 2020 indicated that lead impacts are likely isolated to a small area within the footprint of the former automotive repair shop. Based on the results of previous soil vapor investigations, the highest concentrations of VOCs (principally tetrachloroethene [PCE]) were detected within the northern corner of the former automotive repair shop along East Washington Boulevard.
As described and discussed in the RAW, excavation and offsite disposal of lead-impacted soils and engineering controls including installation of a subterranean parking garage with a ventilation system were selected as the most appropriate removal action for the project site to mitigate potential human exposure to PCE from vapor intrusion.
DTSC utilized information and analysis in the Washington Boulevard / Los Angeles Street Mixed-use Project Initial Study / Mitigated Negative Declaration (MND) and Addendum to support a final determination about the type of environmental document required to be prepared for the 200 East Washington Boulevard Removal Action Workplan as provided by Sections 15162, 15163, and 15164 of the California Environmental Quality Act (CEQA) Guidelines. The MND was adopted by the City of Los Angeles on November 9, 2018. The Addendum evaluated the potential environmental effects of the RAW. The revisions incorporate changes in the previously approved project to include the cleanup and haul away associated with the proposed remediation action of the Site.
