Double E pipeline, designed to deliver natural gas from northern Delaware Basin to Waha hub in west Texas, recently received a favorable environmental assessment from Federal Energy Regulatory Commission. FERC said the project will not significantly affect the human environment. The 135-mile pipeline is jointly owned by subsidiaries of Summit Midstream Partners (70 percent) and ExxonMobil (30 percent). Summit expects to commission the pipeline in 2021. It will include trunklines and laterals connecting production in New Mexico and Texas through Eddy and Lea counties in New Mexico and Loving, Pecos, Reeves and Ward counties in Texas. Shipping capacity is 1.35 billion cubic feet per day.
