The Western Gateway project will facilitate the transportation of refined products from origin points in Texas to key downstream markets in Arizona and California, with connectivity to Las Vegas, Nevada via Kinder Morgan’s CALNEV Pipeline.
The open season commenced at 12:00 pm Central Time on 20 October 2025, and will close at 12:00 pm Central Time on 19 December 2025.
The Western Gateway Pipeline will be a partnership between Phillips 66 and Kinder Morgan to create incremental capacity for refined products from Borger, Texas to Arizona and California.
The Western Gateway Pipeline will consist of a new-build pipeline from Borger, Texas to Phoenix, Arizona, combined with Kinder Morgan’s existing SFPP, L.P. pipeline from Colton, California to Phoenix, Arizona, which will be reversed to enable east to west product flows into California. The Western Gateway Pipeline will be fed from supplies connected to Borger, Texas as well as supplies already connected to SFPP’s system in El Paso, Texas. The Gold Pipeline, operated by Phillips 66, which currently flows from Borger to St. Louis, will be reversed to enable refined products from midcontinent refineries to flow toward Borger and supply the Western Gateway Pipeline. The Western Gateway Pipeline will connect Midwest refinery supply to Phoenix and California, with connectivity to Las Vegas, Nevada via Kinder Morgan’s CALNEV Pipeline.
