(C) acquiring an interest in land or airspace, including land for future airport development, that is needed— (i) to carry out airport development described in subclause (A) or (B) of this clause; or (ii) to remove or mitigate an existing airport hazard or prevent or limit the creation of a new airport hazard. (D) acquiring land for, or constructing, a burn area training structure on or off the airport to provide live fire drill training for aircraft rescue and firefighting personnel required to receive the training under regulations the Secretary prescribes, including basic equipment and minimum structures to support the training under standards the Administrator of the Federal Aviation Administration prescribes. (E) relocating after December 31, 1991 , an air traffic control tower and any navigational aid (including radar) if the relocation is necessary to carry out a project approved by the Secretary under this subchapter or under section 40117. (F) constructing, reconstructing, repairing, or improving an airport, or purchasing capital equipment for an airport, if necessary for compliance with the responsibilities of the operator or owner of the airport under the Americans with Disabilities Act of 1990 ( 42 U.S.C. 12101 et seq.), the Clean Air Act ( 42 U.S.C. 7401 et seq.), and the Federal Water Pollution Control Act ( 33 U.S.C. 1251 et seq.), except constructing or purchasing capital equipment that would benefit primarily a revenue-producing area of the airport used by a nonaeronautical business. (G) acquiring land for, or work necessary to construct, a pad suitable for deicing aircraft before takeoff at a commercial service airport, including constructing or reconstructing paved areas, drainage collection structures, treatment and discharge systems, appropriate lighting, paved access for deicing vehicles and aircraft, and including acquiring glycol recovery vehicles, but not including acquiring aircraft deicing fluids or constructing or reconstructing storage facilities for aircraft deicing equipment or fluids. (H) routine work to preserve and extend the useful life of runways, taxiways, and aprons at nonhub airports and airports that are not primary airports, under guidelines issued by the Administrator of the Federal Aviation Administration. (I) constructing, reconstructing, or improving an airport, or purchasing nonrevenue generating capital equipment to be owned by an airport, for the purpose of transferring passengers, cargo, or baggage between the aeronautical and ground transportation modes on airport property. (J) constructing an air traffic control tower or acquiring and installing air traffic control, communications, and related equipment at an air traffic control tower under the terms specified in section 47124(b)(4). (K) work necessary to construct or modify airport facilities to provide low-emission fuel systems, gate electrification, and other related air quality improvements at a commercial service airport if the airport is located in an air quality nonattainment or maintenance area (as defined in sections 171(2) and 175A of the Clean Air Act ( 42 U.S.C. 7501(2) ; 7505a)) and if the airport would be able to receive emission credits, as described in section 47139. (L) a project by a commercial service airport for the acquisition of airport-owned vehicles or ground support equipment equipped with low-emission technology if the airport is located in an air quality nonattainment or maintenance area (as defined in sections 171(2) and 175A of the Clean Air Act ( 42 U.S.C. 7501(2) ; 7505a)), if the airport would be able to receive appropriate emission credits (as described in section 47139), and the vehicles are; (i) used exclusively on airport property; or (ii) used exclusively to transport passengers and employees between the airport and the airport’s consolidated rental car facility or an intermodal surface transportation facility adjacent to the airport. (M) construction of mobile refueler parking within a fuel farm at a nonprimary airport meeting the requirements of section 112.8 of title 40, Code of Federal Regulations . (N) terminal development under section 47119(a). (O) acquiring and installing facilities and equipment to provide air conditioning, heating, or electric power from terminal-based, nonexclusive use facilities to aircraft parked at a public use airport for the purpose of reducing energy use or harmful emissions as compared to the provision of such air conditioning, heating, or electric power from aircraft-based systems. (P) an on-airport project to improve the reliability and efficiency of the airport’s power supply and to prevent power disruptions to the airfield, passenger terminal, and any other airport facilities, including the acquisition and installation of electrical generators, separation of the airport’s main power supply from its redundant power supply, and the construction or modification of airport facilities to install a microgrid (as defined in section 641 of the United States Energy Storage Competitiveness Act of 2007 ( 42 U.S.C. 17231 )).
