The permit will regulate air pollutant emissions from an exploratory drilling operation within the Eastern Gulf of Mexico (EGOM) of the OCS . The proposed project will mobilize the Transocean Discoverer Spirit and associated support vessels for exploratory dr illing and well completion and does not include the establishment of any permanent production platforms. The operation will last no more than two years, and is expected to operate no more than 208 calendar days per year.
