Document Description
The project involves the selection of remedy to address the risk resulting from the release of hazardous waste or hazardous waste constituents at the San Diego gas & Electric (SDG&E), Kearny - Maintenance and Operations Facility. Based on a risk assessment that is documented in the RCRA Facility Investigation (RFI) report dated October 26, 2009, a remedy is required for a 1.3 acre in the center of the site. The remaining 9.2 acres of the 10.5 acre site are suitable for unrestricted use because a risk assessment determined that the cancer risk to the hypothetical residential receptor is less than the point of departure of one in one million and the hazard index is less than one. This CEQA Notice of Exemption deals only with the remedy for the 1.3 acre impacted area.

Reasons for Exemption
The following factors were considered important when determining that the project was exempt:
1. The proposed remedy is administrative only; no physical changes or active remediation is planned.
2. The remedy covers a small portion (1.3 acres) of the 10.5 acre site.
3. The site is presently zoned for industrial use and the restrictions imposed by the LUC will not change or impede existing site use.
4. Groundwater impacts at the site, for which no remedy is planned, are minimal with total contaminant mass estimated at less than 0.2 kilograms. The remedy options considered in the CMS report to cleanup groundwater were ruled to be not reliable or effective for technical reasons based on site conditions.
5. Modeling indicated the groundwater contaminants will not migrate beyond the LUC boundary at concentration exceeding Maximum Contaminant Levels.
