FEDERAL COMMUNICATIONS COMMISSION

47 CFR Parts 2 and 90

[ET Docket No. 04-243; FCC 04-156]


Narrowbanding for Private Land Mobile Radio Service

AGENCY: Federal Communications Commission.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: This document proposes to revise our transition plan for 
Private Land Mobile Radio (PLMR) licensees in the 150.05-150.8 MHz, 
162-174 MHz, and 406.1-420 MHz bands. This action will provide for an 
orderly transition from wideband to narrowband operations, increase 
spectrum efficiency, maintain compatibility with Federal operations, 
permit PLMR licensees to operate using existing equipment with greater 
confidence that their critical operations will not be suddenly required 
to cease transmissions, and significantly reduce the probability that 
wideband PLMR operations will interfere with new Federal operations.

DATES: Written comments are due September 2, 2004, and reply comments 
are due September 17, 2004.

ADDRESSES: Office of the Secretary, Federal Communications Commission, 
445 12th Street, SW., TW-A325, Washington, DC 20554.

FOR FURTHER INFORMATION CONTACT: Tom Mooring, Office of Engineering and 
Technology, (202) 418-2450, TTY (202) 418-2989, e-mail: 
[email protected].

    Pursuant to Sec. Sec.  1.415 and 1.419 of the Commission's rules, 
47 CFR 1.415, 1.419, interested parties may file comments on or before 
September 2, 2004, and reply comments on or before September 17, 2004. 
Comments may be filed using the Commission's Electronic Comment Filing 
System (ECFS) or by filing paper copies. See Electronic Filing of 
Documents in Rulemaking Proceedings, 63 FR 24121 (May 1, 1998). 
Comments filed through the ECFS can be sent as an electronic file via 
the Internet to http://www.fcc.gov/e-file/ecfs.html. Generally, only 
one copy of an electronic submission must be filed. If multiple docket 
or rulemaking numbers appear in the caption of this proceeding, 
however, commenters must transmit one electronic copy of the comments 
to each docket or rulemaking number referenced in the caption. In 
completing the transmittal screen, commenters should include their full 
name, U.S. Postal Service mailing address, and the applicable docket or 
rulemaking number. Parties may also submit an electronic comment by 
Internet e-mail. To get filing instructions for e-mail comments, 
commenters should send an e-mail to [email protected], and should include 
the following words in the body of the message, ``get form  PLMR licensees employing wideband channels for Hydro, 
forest fire-fighting, conservation, and public safety operations modify 
or discontinue operations if, after January 1, 2005, these wideband 
operations cause interference to new Federal operations in the 162-174 
MHz band, or if, after January 1, 2008, these wideband operations cause 
interference to new Federal operations in the 150.05-150.8 MHz and 
406.1-420 MHz bands;
     Hydro channel licensees operating on the center 
frequencies 169.575 MHz, 409.675 MHz, 409.725 MHz, and 412.625 MHz 
cease operations not later than January 1, 2013 for Industrial/Business 
Pool licensees and not later than January 1, 2018 for Public Safety 
Pool licensees;
     PLMR applicants requesting authority to operate Hydro, 
forest fire-fighting, conservation, public safety, and medical 
radiocommunication stations in the 162-174 MHz band use narrowband 
channels after January 1, 2005; and that these applicants use 
narrowband channels after January 1, 2008 in the 150.05-150.8 MHz and 
406-416 MHz bands; and
     New Hydro stations that would operate on the center 
frequencies 406.125 MHz and 406.175 MHz be limited to a transmitter 
output power of 125 watts and required to coordinate with the Radio 
Astronomy Observatory at Socorro, New Mexico.
    53. If a licensee is required to modify its operations, we believe 
that the licensee would either buy new narrowband equipment or that the 
licensee would hire a vendor to modify some or all of its wideband 
equipment. We are uncertain of the exact costs relating to the 
narrowbanding requirements. We request comment on the costs related to 
narrowbanding and whether these costs would be borne as part of the 
licensee's normal depreciation and replacement cycle. We are especially 
interested in comments dealing with whether small entities would be 
affected disproportionately.

E. Steps Taken To Minimize Significant Economic Impact on Small 
Entities, and Significant Alternatives Considered

    54. The RFA requires an agency to describe any significant 
alternatives that it has considered in reaching its proposed approach, 
which may include the following four alternatives (among others): (1) 
The establishment of differing compliance or reporting requirements or 
timetables that take into account the resources available to small 
entities; (2) the clarification, consolidation, or simplification of 
compliance or reporting requirements under the rule for small entities; 
(3) the use of performance, rather than design,

[[Page 46470]]

standards; and (4) an exemption from coverage of the rule, or any part 
thereof, for small entities.\13\
---------------------------------------------------------------------------

    \13\ 5 U.S.C. 603(c).
---------------------------------------------------------------------------

    55. So long as incompatibilities are not created with Federal 
narrowband operations, we propose to allow incumbent Public Safety Pool 
licensees to use existing equipment until January 1, 2018, and to allow 
incumbent Industrial/Business Pool licensees to use existing equipment 
until January 1, 2013. The Commission proposed that the 14 licensees of 
the six Hydro channels being deleted from the Hydro Channel Plan modify 
their equipment and station licenses and migrate to a center frequency 
listed in the new Hydro Channel Plan on a timetable as advised by the 
Hydro Committee and approved by NTIA and the Commission. The Commission 
proposed to grandfather indefinitely those incumbent stations that 
operate on the frequencies 150.7825 MHz and 150.7975 MHz.
    56. The Commission request comment on whether it should exempt 
equipment designed for use in these Federal bands from our current 6.25 
kHz equipment certification requirement, which is scheduled to commence 
on January 1, 2005. The purpose in providing this alternative is to 
determine whether such a policy would be beneficial or detrimental to 
enabling sharing between PLMR licensees and Federal users.

F. Federal Rules That May Duplicate, Overlap, or Conflict With the 
Proposed Rules

    57. None.

Ordering Clauses

    58. Pursuant to sections 1, 4(i), 7(a), 301, 302(a), 303(f),
