Document Description
The Project is comprised of two sites, including the former Mouren-Laurens Oil Company, Inc. site (MLOC Site) and Leach Oil Company, Inc. site (LOC Site; collectively Site or Sites), which are situated next to each other in an unincorporated portion of Los Angeles County near the City of Compton, California. Due to historic hazardous uses on-site dating back to the 1940’s, the Project proposes to implement the Project-specific Remedial Action Plan (RAP), approved by the Regional Water Quality Control Board (RWQCB) in 2021, to address the contamination of the Project site through a series of remedial actions including a Phase I Environmental Site Assessment (ESA); pre-remediation demolition; used oil removal; volatile organic compound (VOC) removal methods including soil vapor extraction and air sparging; and provision of cover systems to meet the cleanup goals of protecting human health and the environment, maintaining protection over time, and minimizing untreated waste on-site. Implementation of the RAP would occur in phases between February 2024 and March 2025. Remediation will be monitored over time and implementation is anticipated to take anywhere from 7 to 15 years.
