Substantial Local Emissions Reductions

As a petroleum refiner, Tesoro’s operations include converting crude oil into useful products, such as gasoline, diesel and jet fuel. Air emissions – such as greenhouse gases (CO2e), nitrogen oxides (NOx), sulfur oxides (SOx), carbon monoxide (CO), volatile organic compounds (VOCs) and particulate matter (PM) – are by-products of the conversion process. We carefully manage air emissions through the use of environmental management systems at our refineries and logistics facilities. Following strict federal, state and local laws and regulations, we track, monitor and report our emissions data to government agencies on a regular basis to ensure compliance. Our comprehensive environmental and incident systems also help us to monitor and track our air emissions and take specific actions to reduce them.

The LARIC project is expected to have the following impacts on the Los Angeles Refinery’s local emissions. These emissions reductions will help Tesoro continue to meet stringent state and regional air quality requirements, which are among the strictest in the country.

  • Reduce local greenhouse gas emissions (GHG/CO2e) by more than 70,000 metric tonnes annually – the equivalent of removing more than 13,500 passenger vehicles from local roads each year
  • Reduce local NOx emissions by 56 tons per year
  • Reduce local SOx emissions by 3 tons per year
  • Increase local VOC emissions by 75 tons year*
  • Reduce local CO emissions by 85 tons per year
  • Reduce local PM emissions by 3 tons per year

* After offsets, the estimated VOC emission increase is 9 tons per year. VOC emissions require compliance/offsetting in accordance with Regulation XIII. Tesoro will use its internally generated VOC Emission Reduction Credits for offsets.

At Tesoro, we’ve focused our emissions reductions efforts primarily on energy conservation and efficiency. As we pursue strategies to reduce our environmental impact, we consider ways to better track and reduce air emissions from our operations. When evaluating new projects and opportunities, we carefully review potential impacts associated with the project, including energy usage and GHG intensity. We remain committed to implementing programs that will improve air quality and mitigate our impact on the environment and local communities.
