Summit Midstream Partners LLC announced that it has closed the $207 million acquisition of ETC Canyon Pipeline LLC from La Grange Acquisition LP, a wholly-owned subsidiary of Energy Transfer Partners LP. Canyon gathers and processes natural gas in the Piceance and Uinta basins in Colorado and Utah, primarily under long-term, fee-based agreements with more than 50 customers including WPX Energy, Noble, Black Hills, Laramie, Encana, ExxonMobil, and Antero. The gas gathering and processing system consists of more than 1,600 miles of pipe, 44,000 horsepower of compression, processing assets with a total capacity of 97 MMcf/d, and two NGL injection stations.

The Canyon assets will be held in Red Rock Gathering Company LLC, a wholly-owned subsidiary of Summit Investments, which also owns a gathering system in the Sand Wash Basin in northern Colorado that was acquired in the second quarter of 2012.

Summit Investments also announced that Red Rock has two new fee-based commercial agreements with WPX Energy Rocky Mountain LLC and Black Hills Exploration and Production Inc. Each of these new agreements include long-term acreage dedications and collectively provide more than 350 Bcf of minimum volume commitments. Red Rock will expand its existing gathering and compression services for WPX by constructing gas gathering infrastructure to connect new WPX production in the Rifle, Colo. area. Red Rock will also construct a processing plant and related gas gathering infrastructure in the DeBeque, Colo. area, which will support Black Hills' future development of their liquids-rich Mancos and Niobrara acreage. The WPX project will be developed and commissioned over the next several years and the Black Hills project is expected to be completed by the end of 2013.
