On July 1, 2020, the U.S. Court of Appeals for the Fourth Circuit dismissed Howard County, Maryland’s, petition to review the Federal Aviation Administration’s approval (FAA) of construction at Baltimore-Washington International (BWI) Airport as inconsistent with the National Environmental Policy Act (NEPA). NEPA requires the federal agencies to conduct environmental assessments of federally licensed projects to determine whether the project will have significant environmental effects. In 1994, Congress provided for a 60-day limitations period covering challenges to certain projects. This limitations period includes challenges to the adequacy of the NEPA review (NEPA does not contain a statute of limitations provision). 49 U.S.C. § 46110(a).
