Advanced Technology

Modern energy pipelines, including the Western Gateway Pipeline, are built and operated as high-tech, data-driven systems engineered to maximize efficiency while upholding the highest standards of safety, public protection, and environmental stewardship. By integrating continuous real-time monitoring, advanced internal diagnostic tools, and automated valve technology, modern operators ensure proactive maintenance and rapid response capabilities across every mile of infrastructure. The Western Gateway Pipeline will utilize Supervisory Control and Data Acquisition (SCADA), systems which stream high-frequency data—including operating pressure, flow rates, fluid temperature, and valve status—from hundreds of sensors stationed along the pipeline route directly to certified controllers. The pipeline can be shut down remotely at the first sign of an irregularity in operations.

Renewable Energy Efforts

Phillips 66 is one of the world's largest producers of sustainable aviation fuel (SAF). Its Rodeo Renewable Energy Complex in California — a former conventional refinery converted to renewable production — can produce up to 150 million gallons of neat SAF annually, and its Humber Refinery in the U.K. was the first in the country to produce SAF at commercial scale. In 2025, Phillips 66 achieved a 3 to 10 percentage point reduction in carbon intensity for SAF and renewable diesel at the Rodeo complex compared to initial lifecycle calculations, and renewed international sustainability certifications (ISCC EU, PLUS, and CORSIA) across its renewable fuel operations. The company has also secured SAF supply agreements with major airlines and cargo operators and nearly quadrupled its purchases of renewable feedstocks — used cooking oil, tallow, and similar waste-based materials — from 2.6 million barrels in 2021 to 20.9 million barrels in 2025.

Kinder Morgan's Energy Transition Ventures team evaluates commercial opportunities associated with lower-carbon energy. The company has established a renewable natural gas (RNG) platform and is evaluating opportunities across the carbon capture and sequestration value chain. Kinder Morgan also handles other lower-carbon fuels, including ethanol, renewable diesel and biodiesel.

HF Sinclair produces renewable diesel by converting waste fats and oils into fuel that integrates seamlessly into existing petroleum infrastructure and can be transported by pipeline, rail or truck. Its renewable diesel is up to 80% less emissions intensive than traditional fossil fuels. In 2025, HF Sinclair produced more than 208 million gallons of renewable diesel, providing customers with a reliable and sustainable alternative to traditional diesel. The company believes that its ability to supply low-carbon fuels can play an important role in helping achieve GHG emissions reductions in a dependable and scalable way.

Frequently Asked Questions

Are pipelines safe?

Safety is our highest priority, and we are committed to operating the pipeline in a way that helps prevent incidents and minimizes risk. We acknowledge that, as with any mode of transportation, including cargo ships, commercial trucks, or railcars, that incidents can and do occur when transporting liquid energy products. However, public data and federal regulatory reviews consistently establish that pipelines are the safest, most efficient method for moving these critical resources over long distances.

Will the Western Gateway Pipeline prolong the use of fossil fuels and delay the use of alternative energy?

We respect and support the region's long-term transition toward alternative energy grids. A responsible energy transition requires maintaining an absolute baseline of energy security for communities and families today. Right now, Southwest and Western communities face a severe near-term energy crisis. California’s traditional refining capacity is dropping by 17%-20%, which has already triggered supply shortages. For the foreseeable future, local emergency vehicle fleets, regional agricultural networks, grocery logistics trucks, school buses, and our communities require stable liquid fuels to operate. The Western Gateway Pipeline would provide the economic and structural insulation the Southwest and West needs to move safely toward tomorrow's lower-carbon solutions without risking devastating energy poverty.

Will this pipeline route pass through or endanger sensitive environmental areas, like the San Pedro River Valley or the Sonoran Desert Conservation Plan lands?

Currently, route planning for the Western Gateway Pipeline is ongoing, and the final route remains fluid as we work through landowner, environmental, permitting, and other important considerations. Amongst the current options, we are evaluating routes that could traverse parts of the San Pedro River Valley. Phillips 66 is working with the Bureau of Land Management, Arizona Game and Fish and other appropriate agencies to evaluate the best route and ensure sensitive ecological systems are handled in accordance with agency guidance. Environmental impact assessments, cultural resource surveys and regulatory reviews will continue as the route selection is finalized. Where practical, the project will continue to evaluate and prioritize co-location with existing infrastructure and rights-of-way.

How will the pipeline protect local groundwater and agricultural water rights from potential leak or contamination risks?

We know that in the American West and Southwest, water is the lifeblood of our communities, agriculture, and daily survival. The Western Gateway Pipeline utilizes a multi-layered safety program designed to detect anomalies instantly. The system will be continuously monitored 24/7/365 from a centralized dispatch center using real-time telemetry and computational pipeline monitoring software known as a SCADA (Supervisory Control and Data Acquisition) system. If even a minor drop in pressure is detected, automated, remote-controlled isolation valves can be closed within minutes to completely isolate line segments and stop product flow immediately. Furthermore, we conduct continuous, routine inline inspections using advanced tools called smart pigs that scan the pipeline from the inside out to map anomalies or minor signs of stress before they can evolve into an operational issue. Inspections will also occur above ground and via aerial surveys. Utilizing these methods of safety and inspection we are able to protect groundwater and agricultural water.

How are you ensuring that Indigenous Sovereignty and Tribal Nations are respected, given past national conflicts surrounding pipeline approvals?

Our relationship with Sovereign Tribal Nations is guided by a strict philosophy of early, open, and continuous dialogue. Western Gateway Pipeline is actively sitting down with Tribal leaders, Elders, and historic preservation offices while our project is still in preliminary planning stages. We are fully committed to active listening to ensure that sacred lands, cultural resources, and localized environmental priorities are integrated directly into our decision-making parameters.

Will the Western Gateway Pipeline still go through permitting even with the environmental changes under the current administration?

The Western Gateway Pipeline remains fully committed to complying with all applicable environmental and safety standards. Our development process is built on long-term sustainability, operational integrity, and strict adherence to rigorous engineering and environmental guidelines. Should the project proceed into its next phases, any proposed route will be subject to appropriate environmental surveys, cultural resource assessments, and formal regulatory consultations. Federal frameworks represent only a single layer of a highly complex, multi-jurisdictional process. A significant portion of permitting takes place at the state, county, and municipal levels.

Is this a data center project?

No, Western Gateway is not a data center project. Western Gateway is a refined petroleum products pipeline built to move fuels like gasoline, diesel, and jet fuel to communities across the Southwest and West.
