Document Description
The project involves the installation of a vapor intrusion mitigation system (VIMS) comprised of a chemically rated vapor barrier liner and perforated sub-slab soil vapor collection piping within the 2550 Irving Street Affordable Housing project (Site). The Response Plan summarizes the evaluation of remedial alternatives and proposed response actions to protect human health and the environment. This alternative would additionally provide institutional controls to ensure long-term protection from residual soil gas impacts through a Land Use Covenant (LUC) and includes a VIMS Operations and Maintenance Plan (O&M Plan), California Land Reuse and Revitalization Act (CLRRA)-type Site O&M Agreement, Financial Assurance, and voluntary/prudential 5-Year Reviews.

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 is a response 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. No County or Bay Area Air Quality permits are anticipated to be required for the operation of the VIMS.
4. The project will be consistent with applicable state and local environmental permitting requirements. A grading permit from the City of San Francisco will be obtained if one is needed apart from the site development permit. No County or Bay Area Air Quality permits are anticipated for the mitigation.
5. The exceptions pursuant to Cal. Code Rags., title 14, § 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 view of 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 is not expected to cause a substantial adverse change in the significance of a historical resource because none are anticipated.
