Cleaner, More Efficient Operations

Tesoro plans to invest $460 million to physically connect, further integrate and upgrade our adjacent Carson and Wilmington facilities, so that our combined Los Angeles Refinery operates more cleanly and efficiently. Pending permitting and approvals, the Los Angeles Refinery Integration and Compliance (LARIC) project will improve air quality, substantially reduce local emissions, upgrade refinery equipment and provide significant benefits to the local economy. Tesoro is committed to being a good neighbor in the communities where we operate, and the LARIC project helps us deliver on that commitment.

Project Benefits:

Emissions Reductions: The proposed LARIC project will improve local air quality by substantially reducing the refinery’s greenhouse gas emissions – the equivalent of removing 13,500 passenger vehicles from local roads each year. NOx, SOx, PM and CO emissions also will be reduced. These emissions reductions will help Tesoro continue to meet stringent state and regional air quality regulations.

Modernization: Upgrading existing equipment and adding new equipment enables our two facilities to more efficiently work together as one integrated refinery. This more modern configuration will allow us to retire the Wilmington FCC unit, which generates a significant amount of greenhouse gas emissions.

Good, Local Jobs and Tax Revenues: Our substantial investment in the LARIC project will support the local economy by providing good-paying local jobs, increasing local business revenues and generating millions in tax revenues that can be used for local priorities.

According to the Los Angeles County Economic Development Corporation (LAEDC), Tesoro’s investment in the the project is expected to generate economic activity in Southern California that will create more than 4,000 jobs with nearly $265 million in local labor income and add more than $86 million in total tax revenues.

Safety & Oversight

Our top priority is the safety of our employees, contractors, local communities and the environment. Our refining culture and work environment emphasize personal and process safety, and rigorous maintenance and inspection programs based on industry-recognized practices and standards are part of our everyday operations at the Los Angeles Refinery. All equipment additions and updates resulting from the LARIC project will use “Best Available Control Technology,” meaning the equipment is designed to emit the least amount of emissions possible.

  • In May 2015, The American Fuel and Petrochemical Manufacturers (AFPM) awarded the Meritorious Safety Performance Award to Tesoro’s Los Angeles Refinery for outstanding achievements in safe operations in 2014.
  • In July 2015, Tesoro received an Environmental Excellence award from the Port of Long Beach for performing the best in the Port’s Green Ship Program, which encourages shippers to send their cleanest ships to Long Beach.
  • The City of Carson’s first Gold LEED (Leadership in Energy & Environmental Design) certified building was built at the Los Angeles Refinery.

The Los Angeles Refinery operates under the oversight of numerous federal, state and local regulatory agencies, including the California Division of Occupational Safety & Health, California Air Resources Board, the South Coast Air Quality Management District (SCAQMD) and the U.S. Environmental Protection Agency.

Construction for the LARIC project can only begin after the proposed project has been independently and thoroughly reviewed for environmental impacts and certified, in accordance with the California Environmental Quality Act (CEQA), by SCAQMD, which enforces stringent air quality requirements. This review includes opportunity for public input.
