#### § 101.31 Temporary and conditional authorizations.

(a) *Operation at temporary locations.*

(1) Authorizations may be issued upon proper application for rendition of temporary service to subscribers under the following conditions:

(i) When a fixed station, authorized to operate at temporary locations, is to remain at a single location for more than 6 months, an application for a station authorization designating that single location as the permanent location shall be filed at least 90 days prior to the expiration of the 6 month period;

(ii) The station shall be used only for rendition of communication service at a remote point where the provision of wire facilities is not practicable within the required time frame; and

(iii) The antenna structure height employed at any location shall not exceed the criteria set forth in [§ 17.7 of this chapter](/on/2024-09-20/title-47/section-17.7) unless, in each instance, authorization for use of a specific maximum antenna structure height for each location has been obtained from the Commission prior to erection of the antenna. See [§ 101.125](/on/2024-09-20/title-47/section-101.125).

(2) Applications for authorizations to operate stations at temporary locations under the provisions of this section shall be made upon FCC Form 601. Blanket applications may be submitted for the required number of transmitters. An application for authority to operate a fixed station at temporary locations must specify the precise geographic area within which the operation will be confined. The area specified must be defined as a radius of operation about a specific coordinate (latitude/longitude), or as a county, or as a State. Exception to this specific requirement may be made for exceptionally large areas, such as the continental United States. Sufficient data must be submitted to show the need for the proposed area of operation.

(3) Operations in the 17.8-19.7 GHz band for any services and in the 17.7-17.8 GHz band for MVPD operations are prohibited in the areas defined in [§ 1.924 of this chapter](/on/2024-09-20/title-47/section-1.924). Operations proposed in the areas defined in [§ 1.924 of this chapter](/on/2024-09-20/title-47/section-1.924) may not commence without prior specific notification to, and authorization from, the Commission.

(b) *Conditional authorization.*

(1) An applicant for a new point-to-point microwave radio station(s) or a modification of an existing station(s) in the 952.95-956.15 and 956.55-959.75 MHz band segments; the 3700-4200, 5925-6425, 6525-6875, and 6875-7125 MHz bands; the 10.550-10.680, 10.700-11.700, 12.700-13.150, 13.200-13.250, 17.700-18.300, and 19.300-19.700 GHz bands; and the 21.800-22.000 and 23.000-23.200 GHz band segments (see [§ 101.147(s)(8)](/on/2024-09-20/title-47/section-101.147#p-101.147(s)(8)) for specific service usage) may operate the proposed station(s) during the pendency of its applications(s) upon the filing of a properly completed formal application(s) that complies with [subpart B of this part](/on/2024-09-20/title-47/part-101/subpart-B), if the applicant certifies that the following conditions are satisfied:

(i) The frequency coordination procedures of [§ 101.103](/on/2024-09-20/title-47/section-101.103) have been successfully completed;

(ii) The antenna structure(s) has been previously studied by the Federal Aviation Administration and determined to pose no hazard to aviation safety as required by [subpart B of part 17 of this chapter](/on/2024-09-20/title-47/part-17/subpart-B); or the antenna or tower structure does not exceed 6.1 meters above ground level or above an existing man-made structure (other than an antenna structure), if the antenna or tower has not been previously studied by the Federal Aviation Administration and cleared by the FCC;

(iii) The grant of the application(s) does not require a waiver of the Commission's rules:

(iv) The applicant has determined that the facility(ies) will not significantly affect the environment as defined in [§ 1.1307 of this chapter](/on/2024-09-20/title-47/section-1.1307);

(v) The station site does not lie within 56.3 kilometers of any international border, within areas identified in [§§ 1.924(a)](/on/2024-09-20/title-47/section-1.924#p-1.924(a)) through [(d) of this chapter](/on/2024-09-20/title-47/section-1.924#p-1.924(d)) unless the affected entity consents in writing to conditional operation or, if for any services on frequencies in the 17.8-19.7 GHz band and for MVPD operations in the 17.7-17.8 GHz band, within any of the areas identified in [§ 1.924 of this chapter](/on/2024-09-20/title-47/section-1.924);

(vi) If operated on frequencies in the 10.6-10.68 GHz band, the station site does not lie within any of the following regions:
