On April 10, 2019, President Trump issued two Executive Orders (EOs) to facilitate the construction of primarily energy-related infrastructure, including pipelines. EO 13867, Issuance of Permits with respect to Facilities and Land Transportation Crossings at International Borders, was issued to expedite permitting of facilities crossing the international border, such as oil and gas pipelines to and from Canada. EO 13868, Promoting Energy Infrastructure and Economic Growth, aims to promote efficient permitting processes, reduce regulatory uncertainties, and develop new energy infrastructure.
Additional details on the two EOs are available here.
