The Federal Energy Regulatory Commission set a Dec. 18 deadline to issue an environmental assessment for the Cheyenne Connector Pipeline and Cheyenne Hub Enhancement projects in Colorado, according to the agency’s Oct. 11 notice. The pipeline, proposed by Cheyenne Connector LLC, comprises a 70-mile interstate line to move about 600 million cubic feet per day of natural gas from supply connections in the Denver-Julesberg Basin in Weld County to Rockies Express Pipeline LLC’s Cheyenne Hub. The Cheyenne Hub Enhancement would improve the firm interconnectivity capability of pipelines and distribution systems in and around the hub. A final decision is due by March 18, 2019. Cheyenne Connector is a subsidiary of Tallgrass Energy LP.
