The U.S. Environmental Protection Agency settled with Shell Gulf of Mexico Inc and Shell Offshore Inc. over violations of the Clean Air Act. The violations were tied to oil and gas exploration drilling off the Alaska’s North Slope.
The EPA said inspections showed excess emissions for Shell’s Discoverer and Kulluk drill ship fleets’ air permits. The violations date to the 2012 drilling season. Shell, in the settlement, agreed to pay $710,000 for Discoverer violations and $390,000 for Kulluk violations.
