Addendum to the Final Environmental Impact Report for the Martinez Renewable Fuels Facility (as Revised)

A Final Environmental Impact Report (EIR) for the Renewable Fuels Project (State Clearinghouse No. 2021020289) was prepared and certified by Contra Costa County on May 3, 2022, and a Final Revised EIR was certified by Contra Costa County on June 24, 2025. The Project approved by the May 3, 2022 Final EIR and 2025 Final Revised EIR is referred to as the Approved Project and “Final EIR” in this Addendum. Changes to the Approved Project are evaluated in this addendum and referred to as the Modified Project. The Modified Project proposed four modifications to the Approved Project: (1) Permit 18 additional storage tanks to handle renewable feedstocks and products; (2) adjust the heating value for a foul water stripper thermal oxidizer’s heating value to reflect the unit as-built; (3) add shipments by truck as an alternative to marine vessel and rail to account for locally sourced feedstocks; and (4) add an unloading spot for vacuum trucks operating within the facility at a location within Tract 4.
