Williams Partners Says Certain Operations Shut-In Due to Hurricane

Williams Partners L.P. advises that certain of its interests in the Gulf Coast remain shut-in as a result of Hurricane Katrina.

These interests include the Discovery natural gas gathering, transportation, processing and natural gas liquids fractionation system that runs from the deepwater Gulf of Mexico to a location near Paradis, La., and the Carbonate Trend sour-gas gathering pipeline off the coast of Alabama.

Williams Partners has a 40 percent ownership interest in Discovery, which is operated by a unit of Williams. The Carbonate Trend pipeline is wholly-owned by Williams Partners and operated by a unit of Chevron.

The operators of Williams Partners' interests have begun initial inspections at certain onshore and offshore locations.

Onshore, personnel have re-entered Discovery's Larose, La., processing plant and Paradis, La., fractionator. No significant damage has been detected. Both facilities are experiencing power outages. A generator has been secured and is being delivered to the Larose plant. This alternative source of power is designed to enable limited operations.

Offshore, Williams Partners L.P. is awaiting definitive reports on the Carbonate Trend pipeline and the Discovery natural gas pipeline system that serves gas producers from both onshore and offshore natural gas fields including the deepwater Gulf of Mexico.

The operators have begun initial integrity tests on both the Carbonate Trend and Discovery systems. Both offshore pipeline systems are shut-in pending further inspection.

Williams Partners will continue to monitor its interests to assess the operational and financial impact related to Hurricane Katrina. Williams Partners expects to provide more information on its interests next week.
