Tesoro Los Angeles Refinery Integration and Compliance Project

In June 2013, Tesoro purchased BP West Coast Products (Tesoro Carson Operations) with the intention of integrating this refinery with the adjacent, but not contiguous, Tesoro Wilmington Operations to form the Tesoro Los Angeles Refinery. The Los Angeles Refinery Integration and Compliance project (LARIC project) is the continued integration of Carson and Wilmington Operations into the Tesoro Los Angeles Refinery. Under the Clean Air Act (CAA), the South Coast Air Quality Management District (SCAQMD) is the permitting authority for the Tesoro refineries, with EPA having a responsibility to oversee SCAQMD’s actions.

EPA's Region 9 office in San Francisco made two announcements that pertained to the LARIC project:
  • They concluded that federal Prevention of Significant Deterioration (PSD) permitting provisions, pursuant to 40 CFR 52.21, did not apply to this project, and notified Tesoro and SCAQMD of their determination in a letter dated June 20, 2017.
  • In a separate letter dated June 20, 2017, they notified the SCAQMD that they concluded their review of the Title V permit revisions related to the LARIC project.

In the Documents section below, you can find links to the above-mentioned letters  as well as a link to a file titled “Memo-to-File” which details the Region 9 review of Tesoro’s PSD Applicability Analysis regarding its LARIC Project.
