The Project proposes infrastructure upgrades and maintenance activities along the Box Canyon access road which serves as a critical component of the City of Thousand Oaks Public Works Department wastewater conveyance system. The purpose of the project is to improve the long-term access for maintenance vehicles, improve side canyon drainage transport access road, and ensure the continued reliability of the City’s wastewater infrastructure. The mission of Caltrans is to provide a safe and reliable transportation network that serves all people and respects the environment. Regional access to the site is provided by US Route 101 and State Route 23 (SR 23). Caltrans is a commenting agency on this project and has the following comments: According to the XVII Transportation Section of the Mitigated Negative Declaration Document, construction would be temporary and short in duration occurring over the course of approximately six months beginning in mid-2026 with an approximately eight person crew. The crew would conduct work during weekday hours and would not result in permanent increase in vehicle trips or associated VMT. All construction haul vehicles accessing the State Highway System must use routes approved by Caltrans.

The project location is along the Box Canyon access road. The Lead Agency is the City of Thousand Oaks (City).VCMND. 1) The proposed asbestos concrete replacement may require an asbestos survey of all materials being disturbed, which includes asbestos concrete. If more than 100 sq. ft. of pipeline is to be removed, an asbestos survey is required. If there is more than 100 sq. ft. of pipe material containing more than 1% asbestos, a professional abatement by a licensed asbestos abatement contractor will be required. Alternatively, without a survey, andassuming the pipe is asbestos-containing, it can professionally abated. Note- abatement contractors may be subject to additional notification requirements.More information on asbestos abatement and the different notification forms can be found here. It is important you contact our Compliance Division at 805-303-3708 or [email protected] you have specific questions about air district notification and abatement requirements prior to these activities occurring to ensure compliance with applicable rules and regulations, such as VCAPCD Rule 62.7, to avoid notices of violations being issued. 2) Toxic Air Contaminants (TAC), Page 28. Please include in the air quality impact section of the MND referenced a discussion of how the asbestos concrete replacement activities will reduce the potential of asbestos exposure to construction workers and other sensitive
receptors in the adjacent area, such as the neighborhood community along Calle Yucca. Asbestos is a TAC designated by the state of California known for its effects to cause cancer. Thank you for the opportunity to comment on the . If you have any questions, you may contact me at [email protected].
