El Paso Natural Gas Co. (EPNG) is seeking US Federal Energy Regulatory Commission approval for its Maricopa Lateral Expansion Project in Yavapai County, Arizona. As proposed, project involves the construction of one new compressor station, identified as the Haystack Compressor Station (Haystack CS), located at Milepost 31 along EPNG’s Maricopa Lateral line (Line No. 1203) an existing pipeline originating from EPNG’s San Juan Mainline in Yavapai County, Arizona, and connecting to the greater Phoenix area in Maricopa County, Arizona. The project is designed to create an incremental annual average of 50,517 dekatherms per day of firm natural gas capacity on EPNG Line No. 1203.
The Haystack CS will consist of a Caterpillar 3616/Ariel KBC/6 compressor package, along with auxiliary facilities including cooling equipment and filter separators. Additionally, EPNG will install one 20-inch (508-mm) tie-in facility connecting the Haystack CS to EPNG’s existing Line No. 1203 with suction and discharge lines and appurtenances immediately west of the new compressor station within EPNG’s existing easement.
