natural gas we gather, including several intrastate and interstate pipelines, major industrial end-users and major
power plants. The system is strategically located to facilitate the transportation of natural gas from Texas and
northern Louisiana to pipeline connections linking to markets in the eastern areas of the United States.
Our Minden processing plant is a cryogenic natural gas processing and treating plant located in Webster
Parish, Louisiana. This processing plant has amine treating and ethane recovery and rejection capabilities such
that we can recover approximately 80% of the ethane contained in the natural gas stream. In addition, the
processing plant is able to reject the majority of the ethane when justified by market economics. This
processing flexibility enables us to maximize the value of ethane for our customers. NGLs produced at the
Minden processing plant are delivered to our Black Lake pipeline.
Our Ada gathering system is located in Bienville and Webster Parish in Louisiana and the Ada processing
plant is a refrigeration natural gas processing plant located in Bienville Parish, Louisiana. This low pressure
gathering system compresses and processes natural gas for our producing customers and delivers residue gas
into our Pelico intrastate system. The NGLs produced at the Ada processing plant are transported by truck from
the plant tailgate.
Our Pelico system is an intrastate natural gas gathering and transportation pipeline that gathers and
transports natural gas that does not require processing from producers in the area. Additionally, the Pelico
system transports processed gas from the Minden and Ada processing plants and natural gas supplied from third
party interstate and intrastate natural gas pipelines. The Pelico system also receives natural gas produced in
Texas through its interconnect with other pipelines that transport natural gas from Texas into western
Louisiana. The Pelico system leases 850 MMcf of storage capacity from a third party.
Our Southern Oklahoma system is located in the Golden Trend area of McClain, Garvin and Grady
counties in southern Oklahoma. The system is adjacent to assets owned by DCP Midstream, LLC. Natural gas
gathered by the system is delivered to DCP Midstream, LLC processing plants.
Our Colorado system is comprised of a 75% operating interest in Collbran Valley Gas Gathering, LLC, or
Collbran, and consists of assets in the southern Piceance Basin that gather natural gas at high pressure from
over 20,000 dedicated and producing acres in western Colorado. The remaining 25% interest in the joint
venture is held by Occidental Petroleum Corporation who, along with Delta Petroleum Corporation, are the
producers on the system. The Collbran system underwent expansion, completed in the third quarter of 2009,
which consisted of an additional 24-inch pipeline loop and installation of compression at the Anderson Gulch
site. The expansion increased the pipeline capacity to over 200 MMcf/d and enables gas deliveries to the third-
party Meeker Plant through a downstream connection with Enterprise Products Partners LP. As a result of our
arrangement with Enterprise Products Partners LP, we have decommissioned the processing services at our
natural gas processing plant at the Anderson Gulch site. However, this plant will continue to provide treating
and compression services as needed.
Our Wyoming system consists of over 1,300 miles of natural gas gathering pipelines that cover more than
4,000 square miles in the Powder River Basin in Wyoming. The system gathers primarily rich casing-head gas
from oil wells at low pressure and delivers the gas to a third party for processing under a fee agreement.
Our Michigan system consists of four natural gas treating plants and an approximately 330-mile gas
gathering pipeline system with throughput capacity of 455 MMcf/d; an approximately 55-mile residue gas
pipeline, or Bay Area pipeline; and a 75% interest in Jackson Pipeline Company, a partnership owning an
approximately 25-mile residue pipeline; and a 44% interest in the 30-mile Litchfield pipeline.
Effective January 3, 2012, we own a 100% interest in DCP East Texas Holdings, LLC, or East Texas. In
July 2007, April 2009 and January 2012, we acquired 25.0%, 25.1% and 49.9%, respectively, of the limited
liability company interests in East Texas from DCP Midstream, LLC. Our East Texas system gathers,
transports, compresses, treats and processes natural gas and NGLs. Our East Texas facility may also fractionate
NGL production, which can be marketed at nearby petrochemical facilities. Our East Texas system, located
near Carthage, Texas, includes a natural gas processing complex that is connected to its gathering system, as
well as third party gathering systems. The complex includes the Carthage Hub, which delivers residue gas to
interstate and intrastate pipelines and acts as a key exchange point for the purchase and sale of residue gas in
the eastern Texas region. Our East Texas system consists of approximately 900 miles of pipe, processing
capacity of 780 MMcf/d and fractionation capacity of 11MBbls/d.
