Crestwood Midstream Partners LP

announced today the signing of a memorandum of understanding with Mountaineer Keystone LLC, headquartered in Pittsburgh, Pennsylvania, to construct a 42 mile 16" natural gas gathering system to serve MK's Marcellus Shale development program in Northeast West Virginia. The Tygart Valley Pipeline is expected to be completed by the fourth quarter 2012 and will interconnect with Columbia Gas Transmission's WB Pipeline in Randolph County, West Virginia. The TVP will provide MK and other area producers with access to the growing natural gas markets in the Washington DC and Baltimore areas. Crestwood estimates the TVP project, as currently planned, will cost approximately $70 million. Additionally, Crestwood has announced that it has hired Brian S. Blount as Vice President of Crestwood's newly formed Marcellus Commercial Region, effective December 1, 2011.
