Phillips 66 (NYSE:PSX) and Kinder Morgan, Inc. (NYSE:KMI) today announced an extension of the second open season for the Western Gateway Pipeline (Western Gateway), a newly proposed refined products pipeline system. The second open season provided additional receipt points and deliveries into the Los Angeles market via Kinder Morgan's SFPP Watson to Colton, California line.

Based on continued interest, the extended open season, which will now close on April 15 at noon CT, will provide prospective shippers with additional time to complete commercial evaluations of the recently updated Transportation Services Agreement, including certain rates, and secure internal approvals for remaining capacity on the Western Gateway system.

As previously announced, the initial open season concluded in December with significant shipper interest, including shipper commitments.
