DENVER—June 29, 2009—MarkWest Pioneer, L.L.C., a joint venture between affiliates of MarkWest Energy Partners, L.P. (NYSE: MWE) and ArcLight Capital Partners, LLC, announced today a non-binding open season / reverse open season through 5:00 p.m. MDT on July 20, 2009, for incremental firm transportation service on the Arkoma Connector pipeline.
The Arkoma Connector pipeline, which is currently under construction and near completion, is a 50-mile interstate pipeline that will provide new Woodford Shale takeaway capacity and interconnects with Midcontinent Express Pipeline and Gulf Crossing Pipeline.
MarkWest Pioneer has received inquiries regarding additional firm transportation service on the Arkoma Connector and is conducting this non-binding open season to gauge market interest in a possible expansion of the pipeline. In conjunction with the non-binding open season, MarkWest Pioneer is conducting a non-binding reverse open season for existing shippers to express interest in turning back all or a portion of their current firm transportation entitlements.
Following the non-binding open season / reverse open season, MarkWest Pioneer will determine whether to proceed with an expansion of the pipeline and the size, scope, and timing thereof.
Additional information, including the Non-Binding Service Request Form and Turnback Proposal Form, can be obtained on the Arkoma Connector Pipeline website at www.arkomaconnector.com. Questions regarding the non-binding open season / reverse open season should be directed to Bert Dillman, Vice President of Business Development at MarkWest, at (713) 965-0742 or email@example.com.
