Big Pine Gathering System™ Project

Project Overview

The Big Pine System is 55 miles of 20- and 24-inch gathering pipeline, extending through the heart of the Pennsylvania Marcellus shale play in Butler, Armstrong, Indiana and Westmoreland counties. Gas gathered by the Big Pine System is delivered to three interstate transmission lines located in Butler, Indiana and Westmoreland counties.

A 10.5 mile extension and expansion that will connect the system to a residue line at MarkWest’s Bluestone Plant in Butler County is currently underway. This ongoing project also includes construction of a compressor station in Armstrong County. Extension and expansion of the line will increase the total capacity by 125,000 dekatherms per day.

Construction Overview

The initial construction of the Big Pine System involved newly built pipeline and several major river crossings. Columbia Midstream met an extremely aggressive schedule to ensure that gas would flow to market the moment producers were ready. This project of exceptional size and scope was delivered in 14 months—an unprecedented accomplishment in the industry.
