Sec. 22.163  Minor modifications to existing stations.

    Licensees may make modifications to existing stations without 
obtaining prior Commission approval provided:
    (a) Classification as minor. The modifications must be minor. 
Modifications to a station are minor if an application filed solely for 
the purpose of obtaining authorization for such modifications would not 
be classified as major in accordance with Sec. 22.123.
    (b) International coordination. The modifications are limited to 
those for which individual coordination of the channel assignment(s) 
with a foreign administration, under applicable international agreements 
and rules in this part, is not required.
    (c) Antenna structure clearance required. For any construction or 
alteration that would exceed the requirements of Sec. 17.7 of this 
chapter, licensees must notify the appropriate Regional Office of the 
Federal Aviation Administration (FAA Form 7460-1) and file a request for 
antenna height clearance and obstruction marking and lighting 
specifications (FCC Form 854) with the FCC, PRB, Support Services 
Branch, Gettysburg, PA 17325.
    (d) Provision of information upon request. Licensees must supply 
administrative or technical information concerning the modified 
facilities upon request by the FCC. At the time modifications are made 
pursuant to this section, licensees must make a record of the pertinent 
technical and administrative information so that such information is 
readily available. See Sec. 22.303.
    (e) Notification required for modifications affecting CGSA. 
Licensees in the Cellular Radiotelephone Service must notify the FCC 
(FCC Form 489) of any modifications made under this section that cause a 
change in the Cellular Geographic Service Area boundary (including the 
removal of a transmitter or transmitters). The notification must include 
full size and reduced maps, and supporting engineering, as described in 
Sec. 22.953(a)(5) (i) through (iii). If the modification involves a 
contract service area boundary (SAB) extension (see Sec. 22.912), the 
notification must include a statement as to whether the five year build-
out period for the system on the relevant channel block in the market 
into which the SAB extends has elapsed, and whether the SAB extends into 
any unserved area in that market. The notification must be mailed or 
delivered to the filing place (see Sec. 22.106) no later than 15 days 
after the modification is made.
