EnCana has sold the Collbran Valley Pipeline to Enterprise. The construction of this line will start sometime in the fall, and will be a 22 mile, 24-inch pipeline that will start near Molina and end approximately 5 miles West of Parachute.

The first phase East Dry Hollow Loop Pipeline in the Mamm Creek Field was completed in August. Phase two is scheduled to start in September, and should be complete by the end of October. The two phases combined, will be approximately 7 miles of 20-inch pipeline which will allow 3rd party companies to take advantage of EnCana’s existing infrastructure and deliver gas into our system.

The Middle Fork compressor station currently is operating five 7500 HP electric driven compressors. Two more units are scheduled to be online by the end of the year. This will put the total horsepower at 52,500.

The Orchard compressor station currently has one 7500 HP electric compressor operating, with a second scheduled to be installed and operating in October.
