1. Overview of Tesoro (Marathon) Refineries
Tesoro's refineries were known for processing a variety of crude oils, including light sweet crude and heavy sour crude, to produce gasoline, diesel, jet fuel, and other petroleum products. These facilities are strategically located near major markets and transportation hubs.
2. Major Tesoro (Marathon) Refineries
Here’s a look at the key refineries formerly operated by Tesoro before its merger with Marathon Petroleum:

3. Products and Environmental Concerns
- Products: Tesoro refineries produce various products, including gasoline, diesel, jet fuel, asphalt, and petrochemical feedstocks. These products are crucial for transportation, heating, and industrial applications.
- Environmental Concerns: Like other oil refineries, Tesoro's facilities have been subject to scrutiny regarding air and water pollution. Emissions of pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate matter (PM2.5) are of particular concern. The refineries have implemented measures to reduce emissions, comply with regulations, and address community concerns.
4. Transition to Marathon Petroleum
Since Tesoro was acquired by Marathon Petroleum Corporation, these refineries now operate under the Marathon brand. The integration has expanded Marathon's refining capacity and market reach, making it one of the largest refiners in the United States.
