Residents were advised to stay indoors and avoid vigorous outdoor activity if they could see or smell smoke.
Market Impact Assessment
Energy analysts warned of potential impacts on California fuel markets, particularly for jet fuel supplies to LAX. The state's relatively isolated fuel distribution system makes it vulnerable to supply disruptions from major refineries. Previous incidents at California refineries have led to temporary price spikes of 10-20 cents per gallon until supply chains adjusted.
Supply Chain Resilience
Industry experts noted that California maintains strategic fuel reserves and that other refineries could potentially increase production to compensate for temporary disruptions. However, the specialized nature of jet fuel production and California's unique fuel specifications create challenges for rapid supply replacement from outside the state.
Regional Supply Chain: Critical Dependencies and Contingencies
The fire's location in a jet fuel production unit raises particular concerns for aviation operations at Los Angeles International Airport, one of the world's busiest air travel hubs.
Supply Chain Vulnerabilities
- LAX Dependency: The airport consumes approximately 6 million gallons of jet fuel daily, with 40% typically supplied by the Chevron facility
- Pipeline Network: The refinery connects to regional pipeline systems that distribute fuel to airport storage facilities
- Alternative Sources: Other regional refineries and imported supplies could partially offset disruption
- Inventory Levels: Current regional jet fuel inventories estimated at 5-7 days of normal consumption
- Specification Challenges: California's unique jet fuel specifications limit ability to import from other regions
