About us
Martinez Refining Company (MRC) manufactures the cleanest motor fuels in the world, providing an affordable and reliable supply of gasoline, diesel, and jet fuel to the Bay Area.
Our refinery is located on 860 acres and contains 35 process units, each of which plays an important role in how we turn crude oil into fuels that help provide the highest standards of mobility in history.
Our daily workforce consists of 585 full-time employees and 300 embedded contractors. Additionally, 1,000+ Building Trades craftworkers are added during the refinery’s major maintenance activities, which we call “turnarounds.”
In 2024, MRC provided (approximately):
- 25% of the Bay Area’s gasoline supply
- 55% of Oakland and Sacramento Airports’ jet fuel supply
- 40% of San Jose and San Francisco Airports’ jet fuel supply
Martinez Refinery was built in 1915 with significant expansions made in the 1960s, 1980s, and 1990s. Today, it is a modern refinery with advanced automation, controls, and technology. MRC purchased the refinery from Shell in 2020 for $1 Billion and continues to make annual reinvestments in the site between $100 to $300 Million.

The refinery runs internal tests Mondays between 11:00 am and 12:00 pm to ensure our sirens are operational. During the tests on Monday, sirens will typically be heard by our fence line neighbors and potentially beyond. Testing our sirens ensures that we run the refinery to the highest safety standards possible to protect the community, employees, and contract partners.
We have a team of dedicated employees who respond to inquiries 24 hours a day, seven days a week. We invite our neighbors to call our Weekday Phone number at 925-313-3777 or our After-Hours Phone number at 925-313-3601.
Additionally, the Contra Costa County Office of the Sheriff operates the Community Warning System (CWS) and runs additional sire tests. The CWS website states, “Sirens are tested on the first Wednesday of every month at 11:00am. For the remaining Wednesdays, a more quiet and low “growl” test is performed at 11:00am.
