The Tesoro Refining and Marketing Company LLC proposed the original project, the Los Angeles Refinery Integration and Compliance Project (LARIC Project), which was previously analyzed in an Environmental Impact Report that was certified on May 12, 2017 (“May 2017 EIR”). The LARIC Project evaluated in the May 2017 EIR was comprised of modifications necessary to more fully integrate the Tesoro Los Angeles Refinery -Carson and Wilmington Operations to form the Tesoro Los Angeles Refinery (Refinery). The Los Angeles Refinery includes: 1) the Wilmington Operations located at 2101 East Pacific Coast Highway in the Wilmington District of the City of Los Angeles; and 2) the Carson Operations, which is the former BP Carson Refinery located at 2350 East 223rd Street in the City of Carson. In addition, the LARIC Project included modifications at the Carson Crude Terminal located at 24696 South Wilmington Avenue in the City of Carson.
In 2019, revisions to the LARIC Project (“October 2019 Project Revisions”) were proposed and the corresponding October 2019 Addendum to the May 2017 EIR (“October 2019 Addendum”) was certified on November 5, 2019. The October 2019 Project Revisions would: 1) relocate the propane recovery project component from the Carson Operations Naphtha Isomerization Unit to the Carson Operations C3 Splitter Unit; 2) increase the throughput of the Carson Operations Tank 35; and 3) update the construction schedule. The October 2019 Addendum also analyzed updated toxic air contaminant (TAC) crude oil speciation data for six crude oil storage tanks at the Carson Crude Terminal that were approved as a part of the LARIC Project.
To address requirements of the Clean Air Act, Tesoro’s Title V Permits were subsequently circulated for public comment. To address one comment letter received relative to the proposed Title V Permits and the October 2019 Addendum, the South Coast AQMD prepared a Revised Addendum to the May 2017 EIR (“June 2021 Revised Addendum”), which was certified on September 15, 2021. The June 2021 Revised Addendum contains additional analysis but does not include any further project modifications.
