The Connolly Gathering System currently gathers crude oil from various points for delivery to a central delivery point at THPP’s existing Connolly Station. The proposed expansion capacity would provide similar gathering services from additional origin points. Interested shippers will also have an opportunity to make commitments during the open season for firm service on a tranche of expansion capacity on the Connolly Gathering System that THPP previously made available for commitment during an open season in 2014. The total proposed capacity that is available for commitment during the open season will depend on shipper commitments but is estimated to be between 70,000 and 100,000 barrels per day; the capacity of individual laterals will depend on shipper interest. The binding open season commences today and will end at 5:00 p.m. MST on December 15, 2021.
