NOE - Notice of Exemption
Document Description
The project involves approval of a Statement of Basis (SB) for the Former TP Industrial Facility (Site). The SB summarizes the activities to treat contaminants in groundwater through the use of enhanced in-situ bioremediation (EISB), groundwater monitored natural attenuation (MNA), and recording of a land use covenant (LUC) to restrict uses of the property. Current cleanup activities consist of the following: - Injection of organic substrate into dedicated groundwater injection wells and existing groundwater extraction wells to facilitate microorganism growth and degradation of VOCs in groundwater; - Groundwater MNA; and -Recordation of a LUC to restrict uses of the property to industrial/commercial uses. The anticipated start date for this project has not been specifically determined but implementation of EISB is expected to begin during the third quarter of 2021.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Reasons for Exemption
1. The project is a minor action designed to prevent, minimize, stabilize, mitigate or eliminate the release or threat of release of hazardous waste or hazardous substances. 2. The project is a removal action that will not exceed $1 million in cost. 3. The project does not involve the onsite use of a hazardous waste incinerator or thermal treatment unit or the relocation of residences or businesses and does not involve the potential release into the air of volatile organic compounds as defined in Health and Safety Code Section 25123. 4. The project will be consistent with applicable state and local environmental permitting requirements. 5. The exceptions pursuant to Cal. Code Rags., tit. 14, § 15300.2 have been addressed as follows: - Cumulative Impact. The project will not result in cumulative impacts because it is designed to be a short-term, final remedy that would not lead to a succession of projects of the same type in the same place over time. - Significant Effect. The environmental safeguards and monitoring procedures that are enforceable and made a condition of project approval will prevent unusual circumstances from occurring so that there is no possibility that the project will have a significant effect on the environment. - Scenic Highways. The project will not damage scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, because it is not located within view of a highway officially designated as a state scenic highway. - Hazardous Waste Sites. The project is not located on a site which is included on any list compiled pursuant to Section 65962.5 of the Government Code. - Historical Resources. The project will not cause a substantial adverse change in the significance of a historical resource because none are anticipated.
