Notice of Exemption

Exempt Status
Type, Section or Code
Common Sense Exemption [CCR, Sec. 15061 (b)(3)]
Reasons for Exemption
1. The closure activities and post-closure monitoring activities have been implemented. The Landfarms have been closed and DTSC has issued the closure certification. Monitoring data indicates that maintenance of the vegetative cap, the monitoring wells, and the GPS are adequate to contain the release of contaminated groundwater at the Landfarms. No new impact is expected to result from the post closure monitoring and maintenance activities. 2. The continuous implementation of the post-closure maintenance activities, groundwater monitoring program and reporting will document, monitor and maintain the effectiveness of the vegetative cap and the GPS system. The issuance of the Post-Closure Permit serves to enforce the conditions placed on Chevron in order to maintain compliance with the Orders listed in the Project Description above 3. Based on these conclusions, DTSC has determined that the project approval 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 air, water, minerals, flora, fauna, ambient noise, and objects of historic or aesthetic significance." As a result, DTSC finds that the project is exempt from further environmental review under CEQA.
