Phillips 66 and Kinder Morgan have a bold new plan on the table. They want to build the Western Gateway Pipeline—a 1,300-mile system that would move gasoline and refined products from St. Louis out to California.
If things go smoothly, the pipeline could start running by mid-2029. This would be the first project to deliver motor fuels directly into California using a mix of existing pipes and new construction.

The system aims to carry about 200,000 barrels each day. It includes a new route from Borger in the Texas Panhandle to Phoenix, plus a reversed Colton line to keep more fuel in-state, and connections to Las Vegas along the way.
What the Western Gateway Pipeline Could Mean for California and Marin County
This announcement comes at a tense moment for California. The state faces refinery closures that have everyone worrying about supply and price spikes across the Bay Area.
With Phillips 66’s Los Angeles–area twin refinery and Valero’s Benicia plant shutting down, California could lose nearly a fifth of its refining capacity. Supporters argue the pipeline could help stabilize supply for West Coast markets, maybe even ease prices at the pump and reduce the state’s so-called fuel-island vulnerability.
Still, officials keep reminding everyone: nothing’s final yet. The project depends on rock-solid agreements, joint-venture signoffs, and a mountain of environmental and permit reviews.
In Marin County, folks in San Rafael, Novato, Mill Valley, Sausalito, Tiburon, and Corte Madera are paying close attention. The idea of shoring up California’s fuel infrastructure hits home, especially in local debates about energy resiliency, climate goals, and the push to diversify away from oil.
The pipeline might bring more supply options, but Marin communities expect tough environmental protections. They want careful oversight if the state ever approves routes through their scenic, densely packed neighborhoods.
Regional Implications for Marin County and the North Bay
If you commute from Larkspur or San Anselmo to San Francisco or Oakland, the thought of steadier fuel supply could mean more predictable prices at local gas stations. Marin City and Fairfax might especially feel the benefits during wildfire season or big storms, when supply disruptions seem to hit hardest.
On the flip side, critics point out that new pipelines bring risks. The region would need strong hazard reviews, earthquake planning, and emergency strategies before anyone buries a pipeline near Sausalito’s waterfront or Tiburon’s hills.
- Key capacity and route elements: 200,000 barrels per day; a Borger-to-Phoenix segment; California-bound flow by reversing the Colton-to-Arizona line; possible links to Las Vegas markets.
- Timeline and approvals: aiming for service by mid-2029; still needs firm agreements, joint-venture approval, and a thorough slate of regulatory and environmental reviews.
- Regional impact concerns: energy price signals for Marin and the North Bay, plus a sharper focus on environmental protections, air quality, and earthquake resilience.
Public Policy Context and Environmental Considerations
California officials keep stressing the state’s commitment to cutting oil dependence, even as they admit imports and interstate pipelines still matter for supply. In Marin, the debate usually lands on how to balance climate goals with real-world energy needs.
Local leaders in places like Corte Madera, Ross, and San Anselmo want transparent permitting. They insist any new infrastructure must meet strict environmental standards, protect watersheds, and keep scenic byways and coastal views as untouched as possible.
What Marin Residents Should Watch For
As the project moves through regulatory reviews, Marin residents should keep an eye on a few things:
- Environmental impact assessments and public hearings that focus on Marin County air quality and coastal protections.
- Economic implications for fuel prices, local businesses, and commuters in San Rafael, Mill Valley, and Novato.
- Public safety and emergency response planning if construction or operational issues pop up along any route near Marin communities.
As folks in San Anselmo and Sausalito tune in, local coverage will keep digging into what this corridor project could mean for our roads, wallets, and environment. Sometimes it feels like these projects just sneak up on us, doesn’t it?
