The Federal Energy Regulatory Commission has extended until Aug. 27 the limit on emergency transactions by Manta Ray Offshore Gathering Co. LLC (MROG), which has been using its gathering system as an intermediate link in the delivery of natural gas within federal waters offshore Louisiana for nearly four months. On March 1, MROG notified FERC that on Feb. 29 it had initiated the emergency transportation activity to continue the flow of offshore deepwater gas produced in association with oil by Chevron U.S.A. Inc., BHP Billiton Petroleum (Deepwater) Inc. and ExxonMobil Gas & Power Marketing during an outage by Transcontinental Gas Pipe Line Co. LLC (Transco). The need for emergency service became effective Feb. 29 when Transco posted an exception to its resumption of Southeast Louisiana Crossover flow for producers located upstream of its production platform in South Timbalier Block 300. The production would flow on MROG’s gathering system as an alternate transportation route while platform modifications are undertaken, MROG said. MROG filed a notice April 14 to extend the action through June 28, and on June 16 filed a petition seeking a waiver in order to continue the emergency transportation arrangement until Aug. 27.
