The project involves the approval of the Removal Action Work Plan (RAW) for soil, soil vapor, and groundwater containing trichloroethylene (TCE) at 16539 South Main Street, Carson, CA 90248 (Site). The RAW summarizes historic soil, soil vapor, and groundwater investigations and details the excavation of the former subgrade concrete vault soil located inside the building.

Notice of Exemption

Exempt Status
Type, Section or Code
Common Sense, 15061(b)(3)
Reasons for Exemption
DTSC has determined with certainty that there is no possibility that the activities in question may have a significant effect on the environment because the project would not result in "a substantial, or potentially substantial, adverse change in any of the physical conditions within the area affected by the project, including land, air, water, minerals, flora, fauna, ambient noise, and objects of historic or aesthetic significance.” The project is consistent with applicable state and local environmental permitting requirements including, but not limited to, air quality rules such as those governing volatile organic compounds and water quality standards, and approved by the regulatory body with jurisdiction over the site (City of Carson). The majority of remediation activities (e.g., excavation) would occur indoors and would not have the potential to negatively impact adjacent or nearby receptors, which exclusively include industrial land uses. The limited number of trucks (20 total trips) and limited timeframe for activities (maximum of 4 weeks) would also not have the potential to substantially impact existing truck traffic in the project area.
