Atlas Pipeline Partners, L.P., (NYSE:APL) is active in the gas gathering and processing segment of the mid- stream natural gas industry. In the Mid-Continent region of Oklahoma and northern Texas, APL owns and operates approximately 2,200 miles of gas gathering pipeline. APL transports approximately 320 million cubic feet of gas per day from more than 880 receipt points or wells to its gas processing and treating facilities in Velma, Elk City and Prentiss, Oklahoma where natural gas liquids (NGL) and impurities are removed. APL then sells the resulting residue gas and NGL and remits a portion of those proceeds to the producer. In Appalachia, it owns and operates more than 1,440 miles of natural gas gathering pipelines in western Pennsylvania, western New York and eastern Ohio to which more than 4,850 wells are currently connected.
