Document Description
The Department of Toxic Substances Control (DTSC) approved the Corrective Measure Study (CMS) Addendum (CMS Addendum) for the former Printronix/Schlage Lock Company (Site) located at 1700 Barranca Parkway, Irvine, CA 92606. The DTSC determined additional remedial actions were required to address elevated concentrations of volatile organic compounds (VOCs) in soil gas near the southeast property boundary. The remedial action described in the CMS Addendum includes additional Enhanced In-Situ Bioremediation (EISB) injections via direct push in the vicinity of monitoring wells MW-3 and MW-5 and soil vapor extraction near southeast property boundary. The objective of the CMS Addendum is to address potential risk to human health and the environment by remediating groundwater and soil gas using EISB and soil vapor extraction (SVE) system.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Class 30, Categorical Exemption Cal. Code Regs., Title 14, §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 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.
