(a) Notice shall be submitted on FAA Form 7480-1, copies of which may be obtained from an FAA Airport District/ Field Office or Regional Office, to one of those offices and shall be submitted at least - (1) In the cases prescribed in paragraphs (a) through (d) of Section 157.3, 90 days in advance of the day that work is to begin; or (2) In the cases prescribed in paragraphs (e) through (g) of Section 157.3, 90 days in advance of the planned implementation date. (b) Notwithstanding paragraph (a) of this section - (1) In an emergency involving essential public service, public health, or public safety or when the delay arising from the 90-day advance notice requirement would result in an unreasonable hardship, a proponent may provide notice to the appropriate FAA Airport District/Field Office or Regional Office by telephone or other expeditious means as soon as practicable in lieu of submitting FAA Form 7480-1. However, the proponent shall provide full notice, through the submission of FAA Form 7480-1, when otherwise requested or required by the FAA. (2) notice concerning the deactivation, discontinued use, or abandonment of an airport, an airport landing or takeoff area, or associated taxiway may be submitted by letter. Prior notice is not required; except that a 30day prior notice is required when an established instrument approach procedure is involved or when the affected property is subject to any agreement with the United States requiring that it be maintained and operated as a public-use airport. Section 157.7 FAA determinations. (a) The FAA will conduct an aeronautical study of an airport proposal and, after consultations with interested persons, as appropriate, issue a determination to the proponent and advise those concerned of the FAA determination. The FAA will consider matters such as the effects the proposed action would have on existing or contemplated traffic patterns of neighboring airports; the effects the proposed action would have on the existing airspace structure and projected programs of the FAA; and the effects that existing or proposed manmade objects (on file with the FAA) and natural objects within the affected area would have on the airport proposal. While determinations consider the effects of the proposed action on the safe and efficient use of airspace by aircraft and the safety of persons and property on the ground, the determinations are only advisory. Except for an objectionable determination, each determination will contain a determination-void date to facilitate efficient planning of the use of the navigable airspace. A determination does not relieve the proponent of responsibility for compliance with any local law, ordinance or regulation, or state or other Federal regulation. Aeronautical studies and determinations will not consider environmental or land use compatibility impacts. (b) An airport determination issued under this part will be one of the following: (1) No objection. (2) Conditional. A conditional determination will identify the objectionable aspects of a project or action and specify the conditions which must be met and sustained to preclude an objectionable determination. (3) Objectionable. An objectionable determination will specify the FAA-s reasons for issuing such a determination. (c) Determination void date. All work or action for which notice is required by this sub-part must be completed by the determination void date. Unless otherwise extended, revised, or terminated, an FAA determination becomes 753 VerDate Sep<11>2014 08:20 May 17, 2019 Jkt 247048 PO 00000 Frm 00763 Fmt 8010 Sfmt 8010 Y:\SGML\247048.XXX 247048
