DALLAS, Nov. 1, 2013 /PRNewswire/ --Summit Midstream Partners, LLC ("Summit
Investments"), the privately held company that owns and controls the general
partner of Summit Midstream Partners, LP (NYSE: SMLP) and also owns a 71.6%
limited partner interest in SMLP, today provided a commercial and an
operational update for its Meadowlark Midstream Company, LLC ("Meadowlark")
and Red Rock Gathering Company, LLC ("Red Rock") assets.

Meadowlark is comprised of two crude oil and water gathering systems, the
Divide Crude Oil & Water Gathering System (the "Divide System") and the Polar
Crude Oil & Water Gathering System (the "Polar System"), both of which are
located in the Bakken Shale Play in North Dakota, and an associated natural
gas gathering and processing system, the Niobrara Gathering & Processing
System (the "Niobrara System"), located in the Denver-Julesburg Basin in Weld
County, Colorado. Red Rock is a natural gas gathering and processing system
located in the Piceance and Uinta basins with over 1,475 miles of gathering
pipeline, processing assets and two NGL injection stations.

Divide System Update - In October 2013, Summit Investments commenced the
start-up of the Divide System located in Williams and Divide counties in North
Dakota. The Divide System is designed to gather 70,000 barrels of crude oil
and 120,000 barrels of water per day. There are several large independent
producers that have contracted capacity on the Divide System under long-term,
fee-based gathering arrangements. The build-out and completion of the Divide
System will continue into the first half of 2014.

Polar System Update - Summit Investments announced today a significant
expansion of the Polar System located in Williams County, North Dakota. In
addition to the existing 50 miles of crude oil and 35 miles of water gathering
pipeline, Summit Investments will construct 45 miles of new crude oil
gathering pipeline to service an independent producer that is actively
drilling and producing in the area. Pro forma for this expansion, the Polar
System will be capable of handling 100,000 barrels of crude oil and 30,000
barrels of water per day. The expansion is supported by a new 10-year,
fee-based crude oil gathering agreement covering over 30,000 dedicated acres.
The expansion is expected to be in service in the third quarter of 2014.

Niobrara System Update - In September 2013, Summit Investments commenced the
start-up of the Niobrara System located in Weld County, Colorado. The Niobrara
System comprises 89 miles of low-pressure gathering pipeline and a 20 MMcf/d
cryogenic processing plant and interconnects with Colorado Interstate Gas for
its residue gas. Processed NGLs are ultimately delivered to Conway, Kansas
through an interconnect with the Overland Pass Pipeline. Natural gas received
on the Niobrara System is gathered and processed under long-term, fee-based
gathering agreements with several producers, including a large independent
producer serving as the anchor customer under a 10 year, fee-based contract.

Red Rock Update - Summit Investments announced today a new, long-term
agreement with a large independent producer whereby the producer will process
a portion of Red Rock's gathered natural gas at its 60 MMcf/d cryogenic
processing plant located in western Colorado. This agreement will increase
the NGL recoveries from Red Rock's volume throughput. With the execution of
this agreement, Red Rock will decommission its North Douglas processing plant
which will significantly reduce operational expenses.

Red Rock is continuing to develop the 20 MMcf/d cryogenic DeBeque processing
plant which will process liquids-rich Mancos shale production under a
long-term, fee-based agreement with Black Hills Exploration & Production,
Inc. The DeBeque plant is on schedule to commence operations by the end of
2013.

Steve Newby, President and CEO of Summit Investments commented, "We are
excited to bring these important development projects online at Summit
Investments. I want to commend our team for their continued focus on
executing our large project backlog and bringing these development projects in
service on time and on budget. Because of their strategic location in some of
the most active basins in North America, we anticipate significant additional
growth opportunities around these assets in the future."

"The agreement to consolidate our processing operations into a larger, more
efficient facility, and decommissioning of our North Douglas facility at Red
Rock will lead to reduced operating costs for Summit Investments and higher
NGL recoveries for our Red Rock customers. 

The continued organic growth and optimization of these assets at Summit
Investments provides additional scale to our already large inventory of future
drop down opportunities at SMLP."
