A preliminary environmental screening is being conducted as part of the ongoing site selection and feasibility studies. A comprehensive environmental review for each proposed site will be prepared by the FAA pursuant to the National Environmental Policy Act (NEPA). NEPA requires federal agencies to evaluate potential environmental impacts and applies to a federal agency’s decisions and actions, including the approval of the projects proposed by the MLI. The FAA’s environmental review will evaluate the potential environmental impacts and measures to avoid, minimize or mitigate them.
