Document Description
The purpose of the project is to mitigate the low levels of total petroleum hydrocarbon (TPH) and volatile organic compound (VOCs)-impacted groundwater through monitored natural attenuation. Under this alternative, a groundwater monitoring and reporting program would be implemented to demonstrate that contaminant concentrations continue to decrease and to verify that the plume is stable, declining, and not migrating off-Site. The recommended alternative also includes provisions to remove light non-aqueous phase liquid (LNAPL) from the groundwater if it is observed in the future. The project also includes engineering and administrative controls, such as perimeter fencing and a Land Use Covenant (LUC). The project will reduce the risk posed to human health and the environment by subsurface contaminants in groundwater.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
CCR Title 14, Sec. 15330
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 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 exceptions pursuant to California Code of Regulations, Title 14, Section 15300.2 have been addressed as follows: a. 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. b. 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. c. 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 a highway officially designated as a state scenic highway. d. 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. e. Historical Resources. The project will not cause a substantial adverse change in the significance of a historical resource at the Site because there are none at the Site.
