News Release

DENVER, Oct. 15 /PRNewswire-FirstCall/ -- DCP Midstream Partners, LP (NYSE: DPM) (the Partnership) today announced an update assessment of the impact of hurricanes Gustav and Ike on its Discovery system as well as an update on the previously announced pipeline integrity project ongoing at its Douglas pipeline in Wyoming.

As previously announced, Discovery's offshore gathering system sustained storm damage and is not accepting gas from offshore producers while repairs are being made. The Partnership owns a 40% interest in the Discovery system, operated by Williams (NYSE: WMB), which includes an offshore natural gas gathering system, as well as the Larose natural gas processing plant and Paradis fractionation facility. Inspections of the system revealed that an 18-inch lateral was severed from its connection to the 30-inch mainline in 250 feet of water. Williams expects the 30-inch line to be repaired and returned to service by the end of November and the 18-inch lateral to be repaired and returned to service by the end of December 2008.

Neither of the on-shore facilities, located south of New Orleans, sustained significant damage; they are fully operational and processing volumes from onshore sources.

The Partnership's estimate of the net income impact of hurricane-related damages and lost margins on its 40% interest in the Discovery system due to curtailed operations for the third quarter of 2008 has not changed from its initial estimate of approximately $4 million to $7 million, and the impact for the fourth quarter of 2008 is estimated to be approximately $7 million to $12 million. Such amounts include the Partnership's portion of the property insurance deductible. Any repair costs in excess of the insurance deductible are expected to be reimbursed by Discovery's insurance carriers.

As previously announced, the Partnership completed pipeline integrity testing on its Douglas Pipeline in Wyoming and commenced work on the pipeline to bring it back to normal operations. As part of this work, the Partnership has decided to further upgrade the asset to assure future integrity, improve system reliability and reduce operating costs. The Partnership anticipates that this work will be completed in the first quarter of 2009 at a total cost of approximately $13 million, the majority of which is maintenance capital. The Partnership intends to recover the costs of this work over time. The work on the pipeline will be completed in phases so that volumes will return to the system throughout the fourth quarter of 2008 and into the first quarter of 2009.

The Partnership does not expect any impact to the Partnership's regular cash distribution to unitholders for the third and fourth quarters of 2008 due to the hurricanes or pipeline integrity work.

The Partnership has maintained sufficient capacity under its financing facilities to fund the anticipated cash requirements for the Discovery repairs and the pipeline integrity work on the Douglas pipeline.
