A satellite detected a methane cloud over Wyoming much larger than the gas plant from which it likely originated disclosed to regulators.
Tallgrass Energy’s Douglas Gas Plant told regulators it accidentally vented 2.1 metric tons of methane over five separate releases on December 6 and 7, and NASA’s Landsat 9 satellite detected the cloud just before the last release ended. The 4.6-mile cloud required methane to have been released at 76 to184 metric tons per hour, scientists estimated.
