Open Season Extended for Phillips 66 Pipeline Cross-Channel Connector Project

Integrated energy manufacturing and logistics company Phillips 66 (NYSE: PSX) through its wholly owned subsidiary, Phillips 66 Pipeline LLC, is extending its open season for the Cross-Channel Connector project to Dec. 12, 2013. The extension comes at the request of shippers who want additional time to evaluate the project.

The company is soliciting binding commitments to transport refined petroleum products from the south side of the Houston Ship Channel to the Magellan Midstream Partners and Kinder Morgan Energy Partners systems on the north side of the channel at Galena Park and East Houston.

As part of this Cross-Channel Connector project, Phillips 66 Pipeline LLC is proposing to reactivate an idle section of 20-inch diameter pipeline under the Houston Ship Channel and expand an existing 20-inch diameter active line in Pasadena, Texas. The Cross-Channel Connector could be fully operational in 2014, subject to timely market commitments and receipt of the necessary permits and regulatory approval.

Phillips 66 Pipeline LLC leadership is encouraged by the project’s prospects, and potential shippers looking to participate in the open season are requested to execute and submit completed Transportation Service Agreements (TSAs) to Phillips 66 Pipeline LLC by the new deadline.

The binding open season, which commenced at 8:00 a.m. Central time on Thursday Oct. 17, 2013, will end at 5:00 p.m. Central time on Thursday, Dec. 12, 2013, unless further extended by notice provided to all parties who receive the confidential open season documents.
