Phillips 66 Co. and Kinder Morgan Inc. have closed the initial open season for transportation service on the planned 200,000-b/d Western Gateway refined products pipeline system. Based on shipper interest, the company will launch a new open season for remaining capacity on the Western Gateway system in January 2026.

The new open season will include an offering of new destination(s) west of Colton, Calif., via a joint tariff with an existing SFPP line that will be reversed between Watson and Colton, Calif. Through this joint tariff arrangement, Western Gateway shippers will be able to access Los Angeles markets.

Western Gateway pipeline will consist of a new-build pipeline from Borger, Tex. to Phoenix, Ariz., combined with Kinder Morgan’s existing SFPP LP pipeline from Colton, Calif. to Phoenix, Ariz., which will be reversed to enable east-to-west product flows into California. It will be fed from supplies connected to Borger as well as supplies already connected to SFPP’s system in El Paso, Tex.

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. Western Gateway will also have connectivity to Las Vegas, Nev. via Kinder Morgan’s 566-mile CALNEV Pipeline.
