Sec. 90.164  Classification of filings as major or minor.

    Applications and amendments to applications are classified as major 
or minor when such filings concern facilities used to provide commercial 
mobile radio services. Categories of major and minor filings are listed 
in section 309 of the Communications Act of 1934, as amended (47 U.S.C. 
309). In general, a major filing is a request for a Commission action 
that has the potential to affect parties other than the applicant. The 
following are major filings:
    (a) Initial station authorization. Filings for an initial 
authorization as defined in Sec. 90.165(d)(2) are major.

    (b) Ownership or control change. Filings are major if they specify a 
substantial change in beneficial ownership or control (de jure or de 
facto), unless such change is involuntary or if the filing merely amends 
an application to reflect a change in ownership or control that has 
already been approved by the Commission.
    (c) Renewal. Applications for renewal of authorizations are major.
    (d) Environmental. Filings are major if they request authorization 
for a facility that would have a significant environmental effect, as 
defined by Secs. 1.1301 through 1.1319 of this chapter.
    (e) In the Specialized Mobile Radio Service, in addition to filings 
listed in paragraphs (a) through (d) of this section, filings are major 
if they:
    (1) Request a change in frequency;
    (2) Request an authorization that would increase the effective 
radiated power or antenna height above average terrain in any azimuth 
from an existing transmitter authorized to the filer;
    (3) Request an authorization that would relocate an existing fixed 
transmitter;
    (4) Amend a pending application to change a requested frequency;
    (5) Amend a pending application in a way that would increase the 
proposed effective radiated power or antenna height above average 
terrain in any azimuth from an existing transmitter authorized to the 
filer;
    (6) Amend a pending application to change the location of a fixed 
transmitter from that previously proposed in the application; or
    (7) Amend a pending application for which pre-filing coordination 
was required to change the technical proposal substantially from that 
which was coordinated with other users.
