Trihydro is coordinating the Class VI permitting and the California Air Resources Board Low Carbon Fuel Standard (CARB LCFS) permanence certification for a proposed regional center focused on annually sequestering millions of tons of CO2. Additionally, Trihydro is actively engaged in developing the baseline environmental testing and monitoring program for surface and near-surface project areas.

Situated northeast of San Francisco, the Montezuma Carbon project holds the potential to capture and store (sequester) millions of tons of carbon dioxide (CO2) annually from neighboring power plants and industrial facilities. Trihydro is supporting Montezuma Carbon in preparing and submitting essential permits and technical documents to the U.S. Environmental Protection Agency (EPA) Region 9. The Class VI Carbon Sequestration UIC well permit application was submitted by Trihydro in 2023. To complete the application, Trihydro worked with other members of the Montezuma project team, including UC Berkeley, Lawrence Berkeley National Laboratory (LBNL), Svante, and Kiewitt Engineering.

Trihydro is also in charge of designing the surface and near-surface baseline monitoring programs encompassing the atmosphere, vegetation, soil gas, and groundwater at the project site. In addition to these core responsibilities, Trihydro actively assists Montezuma Carbon in pursuing U.S. Department of Energy (USDOE) grant funding, and is preparing the California Air Resources Board (CARB) Site/Project certification application.

Our company needed expert assistance in developing and submitting a US EPA Class VI well application for a large, proposed carbon sequestration project in California. Trihydro led the effort, educated us on how to interface with the new EPA GSDT system, and did it all on budget and schedule. I can’t say enough about the Trihydro team’s capabilities and dedication. Many years ago, we owned one of the West Coast’s leading environmental consulting and contracting companies and have hired tens of technical consultants for complicated and challenging assignments since then. Trihydro is at the top of our list, and I would hire them for any assignment in their wheelhouse with no hesitation.
