The FAA’s Proposed Action is to issue licenses to SpaceX for Falcon 9 launch operations that include boost-backs and landings of the first stage at VAFB or in the Pacific Ocean. The Proposed Action analyzed in the 2016 EA includes construction of a new concrete landing pad and improving infrastructure at SLC-4W, as well as boost-backs and landings of the Falcon 9 first stage on the new pad. The Proposed Action also includes offshore barge landing of the first stage as an option.1 A barge landing would take place no less than 31 miles offshore of VAFB. Under the Proposed Action, launches including boost-backs and landings would occur up to six times per year. The Proposed Action would not change the number of launches (takeoffs) occurring at VAFB.
