Rosecrans Place Response Plan
Document Type
NOE - Notice of Exemption
Document Description
The Project involves the excavation of approximately 2,500 cubic yards of soil contaminated with polychlorinated biphenyls, metals and total petroleum hydrocarbons in shallow soil, primarily shallower than 5 feet below ground surface. In addition, a Vapor Intrusion Mitigation System (VIMS) consisting of passive sub-slab depressurization system coupled with a vapor barrier system will be installed under all the proposed residential development on the Project Site to reduce the potential for vapor intrusion into indoor air from the subsurface. The Department of Toxic Substances Control (DTSC) determined remediation of the Project Site was required to address the contaminates in soil, soil vapor and groundwater at the Project Site. This determination was based upon the findings of the Response Plan which included previous Site Investigations and the selection of the appropriate remedial measures to address the onsite contamination. DTSC approved the Response Plan, prepared by Ramboll, US Corporation.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Section 15330, Class 30
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 will be consistent with applicable State and local environmental permitting requirements. 4. The project does not involve the onsite use of a hazardous waste incinerator or thermal treatment unit. 5. The project does not involve the relocation of residences or businesses. 6. The project does not involve the potential release into the air of volatile organic compounds as defined in Health and Safety Code Section 25123. (Exception: Small-scale in situ soil vapor extraction and treatment systems which have been permitted by the local Air Pollution Control District or Air Quality Management District.) 7. 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.
