Notice of Exemption

Exempt Status
Type, Section or Code
Section 15061(b)(3)
Reasons for Exemption
1. Groundwater monitoring and cleanup activities are ongoing. No new construction was approved. No new treatment activities were required. 2. Sources of contamination in the soil at the site have been remediated to protect human health and the environment. 3. A negative declaration was prepared and certified in 1998 in support of the remediation of site soil and the groundwater extraction and treatment system. 4. DTSC has updated the groundwater monitoring requirements. It revised the Corrective Action Groundwater Monitoring Sampling plan to more adequately monitor the site hydrogeology. Major features of the groundwater monitoring program include: a list of Constituents of Concern, Concentration Limits, Monitoring Points, and a Reporting Program. The changes are minor and reflect additional experience at the site, not a significant new groundwater problem. 5. The postclosure permit includes provisions to restrict future land uses. Any future new use of the site will also require an amendment of the postclosure permit, pursuit to the specific conditions stated therein. A Land Use Covenant and deed restrictions are also in place that limit future use of the property and groundwater and provide notice of its former hazardous waste uses. 6. Recent inspections have revealed no failures or malfunctions in the monitoring or treatment systems.
