The following piece takes a closer look at the Western Gateway Pipeline project from Phillips 66 and Kinder Morgan. This plan aims to boost California’s fuel supply as several in-state refineries shut down or pause operations.
The project targets completion around 2029. It would stretch from St. Louis to California, delivering up to 200,000 barrels per day into Phoenix and changing how gasoline and other refined products move across the West.

In Marin County, folks from San Rafael to Mill Valley, Sausalito to Novato will be watching. This big investment could shape supply reliability, pump prices, and local energy debates for years to come—maybe even longer.
Overview: What the Western Gateway Pipeline Means for California and Marin
Western Gateway is pitched as a lifeline for a state dealing with tighter supplies after refinery closures. By routing more product through a network that reaches California from Gulf Coast refineries and the Southwest, the project hopes to keep more in-state fuel in California instead of sending it elsewhere.
The plan would help California offset a potential loss of up to 20% of refining capacity by mid‑2026. That’s a number that weighs on energy strategies and local economies from Marin to Santa Clara County.
For Bay Area drivers—especially in Marin’s towns like San Anselmo, Fairfax, and Tiburon—the hope is a steadier flow of gasoline and diesel, even as global markets and climate policies push and pull on prices. California’s “premium” at the pump has long frustrated drivers, with critics blaming strict fuel blends and local rules.
Project backers claim greater access to interstate pipelines and more diverse sources could soften price swings and reduce shortages if a single refinery goes offline.
Route, Capacity and Partners: How the Pipeline Would Work
The Western Gateway would run alongside an existing El Paso-to-region pipeline. It would also carry products from Gulf Coast refineries, including those in Houston and Port Arthur.
In simple terms, more product would move toward California without relying only on West Coast or international shipments. Part of the plan involves reversing a segment of Kinder Morgan’s Colton‑to‑Arizona line to send fuel east‑to‑west into California, tapping into a broad network across several states.
Officials say the project could add up to 200,000 barrels per day (bpd) into Phoenix. That would replace the roughly 125,000 bpd Arizona now gets from California.
This reallocation is expected to improve logistical resilience for the region, including the North Bay. Marin shopping corridors and ferry commuters depend on steady fuel for everything from early-morning drives to weekend trips out to Pointe Reyes.
California Refining Capacity, Prices, and Policy Context
California doesn’t have direct access to a big interstate pipeline network. The state has leaned hard on imported fuel by ship and on in-state refining.
With several plants closing or shutting down, refining capacity keeps shifting—and so do pump prices. As of the latest snapshot from project supporters, California’s average price hovered around $5.92 per gallon.
Critics say that’s due to a mix of state policy factors and the cost structures of California refineries and fuels. The Western Gateway is pitched as a long-term way to steady supply and help keep price spikes in check for residents from Corte Madera to Novato.
Governor Newsom’s office described the project as a promising opportunity to strengthen gasoline supply while still pushing to reduce oil dependence and advance climate goals. The administration stressed that public interest and market signals would guide any final agreements.
In Marin’s towns, that means close scrutiny of how pipelines match up with local environmental standards and community concerns. There’s also some recognition of potential benefits for regional fuel reliability, but plenty of questions remain.
What This Could Mean for Marin County Communities
In Marin—from the waterfront neighborhoods of Sausalito to the hills of Larkspur and the busy roads of San Rafael—the Western Gateway could affect both price stability and fuel availability. This is especially true during peak travel seasons or wildfire disruptions.
Local small businesses, school districts, and ferry operators count on predictable fuel costs to budget and plan across the North Bay.
- Potential benefits: Better supply reliability, less risk of shortages during refinery outages, and more moderate price swings that help Marin households manage budgets.
- Possible concerns: Environmental impact, routing through sensitive habitats near San Francisco Bay, and making sure new infrastructure fits Marin’s climate and land-use policies.
- Community opportunities: Collaboration between Bay Area agencies and the project developers to monitor construction impacts and secure local benefits, including jobs and infrastructure improvements in Marin cities like San Anselmo and Fairfax.
Looking Ahead: Timelines, Approvals, and Local Watchfulness
Project organizers say customer interest during the open season highlights Western Gateway’s potential long-term role in refined products logistics across the West.
Final agreements, regulatory approvals, and environmental reviews will shape the pace toward a possible 2029 completion date.
For Marin County residents, it’s a tough balance between fuel resilience and protecting the region’s environmental priorities.
San Rafael council members, Novato planners, and Tiburon residents keep an eye on the process. The North Bay will watch not just the price tag, but also how the pipeline’s economic and ecological footprint fits into Marin’s changing energy future.
