FEDERAL COMMUNICATIONS COMMISSION

47 CFR Part 90

[PR Docket No. 92-235; FCC 99-68]


Private Land Mobile Radio Services

AGENCY: Federal Communications Commission.

ACTION: Final rule; petitions for reconsideration.

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

SUMMARY: This document in PR Docket No. 92-235, addresses petitions for 
reconsideration of, and clarifies certain decisions made in, the Second 
Report and Order in PR Docket No. 92-235, 62 FR 18834, and, where 
necessary, makes appropriate modifications to the rules. Specifically, 
the Commission affirms the decision to limit the eligibility for the 
Public Safety Pool to those entities that were eligible under the 
former Public Safety Radio Services or Special Emergency Radio Service 
(SERS); and modifies the rules to provide that all frequencies--shared 
and exclusive--assigned to the former Power Radio Service, Petroleum 
Radio Service, Railroad Radio Service, and Automobile Emergency Radio 
Service must either be coordinated by the frequency coordinator 
responsible for the service in question prior to the adoption of the 
Second Report and Order, or be coordinated with that coordinator's 
prior written concurrence. The Commission also clarifies several 
aspects of the rules regarding the low power offset channels in the 
450-470 MHz band.

DATES: Effective August 5, 1999.

Summary of the Second Memorandum Opinion and Order

    1. The Second Report and Order consolidated twenty private land 
mobile radio (PLMR) services into two pools, a Public Safety Pool 
consisting of all former Public Safety Radio Services and the Special 
Emergency Radio Service (SERS), and an Industrial/Business Pool 
consisting of the former Industrial and Land Transportation Radio 
Services. It also established provisions designed to facilitate 
development of centralized trunked systems in the shared PLMR bands 
below 800 MHz, and adopted an approach for accommodating low power use 
of the 450-470 MHz band. The Commission received fifteen petitions for 
reconsideration or clarification of the Second Report and Order.
    2. The Commission denies a request to expand the categories 
eligible for the Public Safety Pool to include central station alarm 
companies, because public safety spectrum is scarce, and the requested 
expansion would be inconsistent with the definition of public safety in 
47 U.S.C. 337(f)(2).
    3. The Second Report and Order concluded that any frequency in the 
Industrial/Business Pool could be coordinated by any frequency 
coordinator designated to coordinate any of the services consolidated 
into that pool, except that frequencies formerly assigned exclusively 
to the Power, Petroleum, and Railroad Radio Services could be 
coordinated only by the coordinators for those services. As requested 
by those coordinators, the Second Memorandum Opinion and Order expands 
that exception to include frequencies that formerly were shared by any 
of those services and any other Industrial or Land Transportation Radio 
Services (except 12.5 kHz and 6.25 kHz channels in the 450-470 MHz 
band). In the alternative, the power, petroleum, and railroad 
coordinators may determine that such frequencies may be coordinated by 
any other Industrial/Business coordinator, provided that written 
concurrence is first received from the power, petroleum, or railroad 
coordinator.
    4. In addition, the Second Memorandum Opinion and Order expands the 
exception to include frequencies formerly assigned to the Automobile 
Emergency Radio Service (AERS), but denies requests for similar 
treatment of other frequencies, because only on the AERS are safety-
related communications sufficiently frequent and potentially serious to 
merit such treatment, which is consistent with the definition of public 
safety in 47 U.S.C. 309(j)(2).
    5. The Commission denies the request of the power and petroleum 
coordinators to suspend the acceptance of applications for frequencies 
adjacent to former power and petroleum channels, for there is no 
evidence of a serious adjacent channel interference problem.
    6. After the Commission accepts a proposed channel plan designating 
specific narrowband (12.5 kHz) offset frequencies in the 450-470 MHz 
band for low power operations, it will begin accepting full power 
applications for other the other narrowband offset frequencies in that 
band. Existing low power licensees may relocate to the designated 
frequencies, or may remain on the non-designated frequencies, but only 
on a secondary, non-interference basis. Wideband (25 kHz) operation 
will be permitted on the designated frequencies only on a secondary 
basis (unless a waiver is granted).
    7. The Second Memorandum Opinion and Order classifies as commercial 
mobile radio services (CMRS) all Industrial/Business Pool licensees 
that offer to the public for-profit service interconnected to the 
public switched telephone network. The eligibility requirements for the 
Industrial/Business Pool are the same as those for the former Business 
Radio Service (BRS), and BRS licensees that offered for-profit, 
interconnected service to the public were classified as CMRS. CMRS 
licensees are subject to part 20 of the Commission's rules and Title II 
of the Communications Act of 1934, as amended.
    8. The Second Memorandum Opinion and Order defers to a later date 
consideration of a request to suspend acceptance of applications for 
frequencies that formerly were shared by the Power or Petroleum Radio 
Services and other Industrial or Land Transportation Radio Services, 
issues associated with the trunking of frequencies in systems which 
operate below 800 MHz, and the issue of potential interference to 
medical telemetry systems from PLMR stations operating in the 450-470 
MHz band.

Regulatory Flexibility Act

Final Regulatory Flexibility Analysis

    9. As required by the Regulatory Flexibility Act (RFA), see 5 
U.S.C. 603, Initial Regulatory Flexibility Analyses (IRFA) were 
incorporated in the Notice of Proposed Rule Making and the Further 
Notice of Proposed Rule Making in PR Docket 92-235. The Commission 
sought written public comment on the rule making proposals in the 
Notice and Further Notice, including on the respective IRFAs. This 
present Supplemental Regulatory Flexibility Analysis (Supplemental 
FRFA) in this Second Memorandum Opinion and Order (Second MO&O) 
conforms to the RFA.
    10. Need for, and Objectives of, the Second MO&O. Our objective is 
to increase spectrum efficiency and facilitate the introduction of 
advanced technologies into the 150-174 MHz, 421-430 MHz, 450-470 MHz, 
and 470-512 MHz private land mobile radio (PLMR) bands. The Report and 
Order in this proceeding modified the Commission's rules to resolve 
many of the technical issues which inhibited the use of spectrally 
efficient technologies in these frequency bands. It also stated the 
Commission's intent to consolidate the twenty existing radio service 
pools. The Further Notice in this proceeding proposed several methods 
of introducing market based incentives into the PLMR bands, including 
exclusivity. In the Second R&O, the Commission consolidated the radio 
service frequency pools and addressed related issues such as frequency 
coordination, trunking, and low power frequencies. This Second MO&O 
address petitions for reconsideration and clarification received in 
response to the Second R&O.
    11. The Commission finds that the potential benefits to the PLMR 
community from the promulgation of rules for this purpose exceed any 
negative effects that may result. Thus, the Commission concludes that 
the public interest is served by modifying our rules to consolidate the 
PLMR services and increase the spectral efficiency of the PLMR bands.
    12. Summary of Significant Issues Raised by Public Comments in 
Response to the IRFA. No reconsideration petitions were submitted in 
direct response to the previous FRFAs. The Commission has, however, 
reviewed general comments that may impact small businesses. Much of the 
impact on small businesses arises from the central decision in this 
proceeding--determining the number of frequency pools and the 
eligibility criteria for each pool. This affects small businesses in 
the following way. A smaller number of pools provides a greater number 
of frequencies available for small businesses that use PLMR systems to 
meet their coordination needs. Additionally, by creating fewer pools, 
frequency coordinators will now be subject to competition. Thus, small 
businesses that use PLMR systems can expect to pay lower prices for 
frequency coordination while receiving equivalent or better service. 
Finally, consolidating

[[Page 36260]]

the PLMR services provides each frequency coordinator, which currently 
provides service only for a narrowly defined type of user, with the 
ability to expand its business base.
    13. Description and Estimate of the Number of Small Entities to 
Which Rules Will Apply. The RFA directs agencies to provide a 
description of and, where feasible, an estimate of the number of small 
entities that may be affected by the rules adopted. The RFA generally 
defines the term ``small entity'' as having the same meaning as the 
terms ``small business,'' ``small organization,'' and ``small 
governmental jurisdiction.'' See 5 U.S.C. 601(6). In addition, the term 
``small business'' has the same meaning as the term ``small business 
concern'' under the Small Business Act. 5 U.S.C. 601(3). A small 
business concern is one which: (1) Is independently owned and operated; 
(2) is not dominant in its field of operation; and (3) satisfies any 
additional criteria established by the Small Business Administration 
(SBA). 5 U.S.C. 632. A small organization is generally ``any not-for-
profit enterprise which is independently owned and operated and is not 
dominant in its field.'' 5 U.S.C. 601(4). Nationwide, as of 1992, there 
were approximately 275,801 small organizations. 1992 Economic Census, 
U.S. Bureau of the Census, Table 6. ``Small governmental jurisdiction'' 
generally means ``governments of cities, counties, towns, townships, 
villages, school districts, or special districts, with a population of 
less than 50,000.'' 5 U.S.C. 601(5). As of 1992, there were 
approximately 85,006 such jurisdictions in the United States. U.S. 
Dept. of Commerce, Bureau of the Census, ``1992 Census of 
Governments.'' This number includes 38,978 counties, cities and towns; 
of these, 37,566, or 96 percent, have populations of fewer than 50,000. 
Id. The Census Bureau estimates that this ratio is approximately 
accurate for all governmental entities. Thus, of the 85,006 
governmental entities, the Commission estimates that 81,600 (91 
percent) are small entities.
    14. Estimates for PLMR Licensees. Private land mobile radio systems 
serve an essential role in a vast range of industrial, business, land 
transportation, and public safety activities. These radios are used by 
companies of all sizes operating in all U.S. business categories. 
Because of the vast array of PLMR users, the Commission has not 
developed, nor would it be possible to develop, a definition of small 
entities specifically applicable to PLMR users. For the purpose of 
determining whether a licensee is a small business as defined by the 
Small Business Administration (SBA), each licensee would need to be 
evaluated within its own business area. The Commission's fiscal year 
1994 annual report indicates that, at the end of fiscal year 1994, 
there were 1,101,711 licensees operating 12,882,623 transmitters in the 
PLMR bands below 512 MHz. See Federal Communications Commission, 60th 
Annual Report, Fiscal Year 1994 at 120-121. Further, because any entity 
engaged in a commercial activity is eligible to hold a PLMR license, 
these rules could potentially impact every small business in the U.S.
    15. Estimates for Frequency Coordinators. Neither the Commission 
nor the SBA have developed a definition of small entities specifically 
applicable to spectrum frequency coordinators. Therefore, the 
Commission concluded that the closest applicable definition under SBA 
rules is Business Associations (SIC 8611). See Second R&O, 12 FCC Rcd 
at 14355. The SBA defines a small business association as an entity 
with $5.0 million or less in annual receipts. There are 18 entities 
certified to perform frequency coordination functions under Part 90 of 
our Rules. However, the Commission is unable to ascertain how many of 
these frequency coordinators are classified as small entities under the 
SBA definition. The Census Bureau indicates that 97% of business 
associations have annual receipts of $4.999 million or less and would 
be classified as small entities. The Census Bureau category is very 
broad, and does not include specific figures for firms that are engaged 
in the frequency coordination. Therefore, for the purposes of this 
Supplemental FRFA, the Commission estimates that almost all of the 18 
spectrum frequency coordinators are small as defined by the SBA.
    16. Description of Projected Reporting, Recordkeeping, and Other 
Compliance Requirements. The rules adopted in this Second MO&O do not 
have any general reporting or recordkeeping requirements for PLMR 
licensees. There are, however, a few compliance requirements. First, 
frequency coordinators, when recommending frequencies that were 
formerly allocated on a shared basis to the Petroleum Radio Service, 
must obtain the concurrence of the former Petroleum Radio Service 
frequency coordinator. While the Commission wants to remove as many 
requirements on the licensing process as possible, the Commission 
believes that this requirement is necessary in order to protect 
critical safety-related communications systems. The American Petroleum 
Institute, supported by several commenters, petitioned for protection 
of existing petroleum stations based upon coverage contours. Rather 
than institute a complex requirement based on the computation of 
coverage contours, the Commission believes that the goals of protecting 
these systems can be achieved through a simple concurrence requirement.
    17. Second, the Commission is requiring each of the coordinators 
that have sole management authority over a group of frequencies to 
supply supporting reasons for denying any request for frequency 
coordination on those frequencies. The American Automobile Association 
petitioned for a clarification that would have held these coordinators 
to the same coordination procedures as previously were applicable under 
the former interservice sharing rules. The Commission believes that 
such procedures would be excessive under the new consolidated pool 
structure. Therefore, to guard against summary denials and to promote 
sharing to the greatest degree possible, the Commission believes that 
requiring the coordinators with sole management authority over certain 
frequencies to justify any denials of coordination on those frequencies 
will suffice.
    18. Steps Taken to Minimize Significant Economic Impact on Small 
Entities, and Significant Alternatives Considered. The Commission, in 
this Second MO&O, has considered petitions for reconsideration and 
clarification regarding its Second R&O in PR Docket No. 92-235, which 
consolidated the PLMR radio services below 512 MHz. In doing so, the 
Commission has adopted several proposals which minimize burdens placed 
on small entities. First, the Commission adopted a concurrence 
requirement on frequencies that were allocated to the former Petroleum 
Radio Service on a shared basis. Based on the need to provide 
additional protection to entities operating on these frequencies, 
concurrence is the simplest method of providing this protection. The 
alternative would be to require applicants and frequency coordinators, 
including those that are small businesses, to conduct complex and 
costly contour analyses. Second, the Commission did not expand the 
number of frequencies on which coordinators have sole management 
authority. This decision will ensure the continued benefits of 
consolidation. Namely, entities will have more frequency options than 
if more frequencies were restricted. The increase in frequency choices 
will provide a greater likelihood that licensees, including small 
entities, will share frequencies with fewer systems, enabling them to 
achieve more

[[Page 36261]]

efficiency in their radio systems. Third, the Commission clarifies that 
a coordinator, at an applicant's request, who determines that the most 
appropriate frequency is one that is managed solely by another 
frequency coordinator can forward an application directly to that 
coordinator. The alternative would be to return applications which 
would foster inefficiency, add delays to the coordination process, and 
drive up costs. Fourth, the Commission clarifies and modifies the rules 
regarding designated low power frequencies to (1) allow existing users 
of low power systems that are not currently operating on designated low 
power frequencies to modify their operating frequency to one of the 
designated frequencies and obtain primary status while still using 
wideband equipment, and (2) allow new licensees on the designated low 
power frequencies, all of which are restricted to narrowband 
operations, to obtain authorizations for wideband equipment on a 
secondary basis. Many users and manufacturers of low power systems are 
small businesses and these actions allow for such entities to continue 
to use existing equipment and for manufacturers to deplete, rather than 
scrap, existing inventory. Fifth, the Commission amends the rules to 
require entities to operate in the semi-duplex mode when using former 
Taxicab Radio Service frequencies in metropolitan areas. Such action 
ensures that future authorizations on these channels will be compatible 
with existing taxicab users, many of which are small businesses. Sixth, 
the Commission amends the rules to extend until 2006, the date by which 
new licensees operating on the emergency medical (MED) channels must 
employ equipment capable of operating on all the newly created MED 
channels. Existing licensees on these channels are grandfathered using 
their existing radios. This provides relief to licensees, many of which 
are small businesses, which could not readily comply with the 
originally proposed rule because of lack of available equipment.
    19. The Commission will send a copy of this Second Memorandum 
Opinion and Order including this Supplemental FRFA, in a report to be 
sent to Congress pursuant to the Small Business Regulatory Enforcement 
Fairness Act of 1996, see 5 U.S.C. 801(a)(1)(A). In addition, the 
Commission will send a copy of the Second Memorandum Opinion and Order, 
including Supplemental FRFA, to the Chief Counsel for Advocacy of the 
Small Business Administration. A copy of the Second Memorandum Opinion 
and Order and Supplemental FRFA (or summaries thereof) will also be 
published in the Federal Register. See 5 U.S.C. 604(b).

    (6) Frequencies may be assigned in pairs with the separation 
between base and mobile transmit frequencies being 5.26 MHz. A mobile 
station may be assigned the frequency which would normally be assigned 
to a base station for single frequency operation. However, this single-
frequency operation may be subject to interference that would not occur 
to a two-frequency system. Base or mobile stations operating wholly 
within Standard Metropolitan Areas having 50,000 or more population 
(1950 Census) must be operated in the half-duplex mode.
* * * * *

    (79) Frequencies may be assigned in pairs with the separation 
between base and mobile transmit frequencies being 5.26 MHz. A mobile 
station may be assigned the frequency which would normally be assigned 
to a base station for single frequency operation. However, this single-
frequency operation may be subject to interference that would not occur 
to a two-frequency system. Base or mobile stations located 80.5 km (50 
miles) or less from the center or any urbanized area of 600,000 or more 
population (U.S. Census of Population, 1970) must be operated in the 
half-duplex mode.
    (80) Concurrence from the Petroleum Coordinator is required only 
for applications for this frequency that request authorization for 
transmitters in Arkansas, Louisiana, Oklahoma, or Texas.
    (81) Concurrence from the Petroleum Coordinator is required only 
for applications for this frequency that request authorization for 
transmitters in Arkansas, Louisiana, Oklahoma, Oregon, Texas, or

    6. Section 90.173 is amended by revising paragraph (a) and by 
adding paragraph (j) to read as follows:


Sec. 90.173  Policies governing the assignment of frequencies.

    (a) Except as indicated in paragraph (j) of this section, the 
frequencies which ordinarily may be assigned to stations in the 
services governed by this part are listed in subparts B, C and F of 
this part. Except as otherwise specifically provided in this part, 
frequencies assigned to land mobile stations are available on a shared 
basis only and will not be assigned for the exclusive use of any 
licensee.
* * * * *
    (j) Frequencies other than those listed in subparts B and C of this 
part may be assigned in the 150-174 MHz, 421-430 MHz, 450-470 MHz, and 
470-512 MHz bands, provided the following conditions are met:
    (1) Such applications must be accompanied by a showing of frequency 
coordination in accordance with the requirements of Sec. 90.175;
    (2) The frequencies must not be available in any other rule part of 
this chapter; and
    (3) The authorized bandwidth of any system operating in accordance 
with this paragraph must not overlap spectrum available in other rule 
parts of this chapter unless that spectrum is also allocated in part 
90.
* * * * *
    7. Section 90.175 is amended by revising the first sentence of the

[[Page 36270]]

introductory text and by revising paragraph (b) to read as follows:


Sec. 90.175  Frequency coordination requirements.

    Except for applications listed in paragraph (i) of this section, 
each application for a new frequency assignment, for a change in 
existing facilities as listed in Sec. 90.135(a), or for operation at 
temporary locations in accordance with Sec. 90.137 must include a 
showing of frequency coordination as set forth below. * * *
* * * * *
    (b) For frequencies between 25 and 470 MHz: (1) A statement is 
required from the applicable frequency coordinator as specified in 
Secs. 90.20(c)(2) and 90.35(a)(2) recommending the most appropriate 
frequency. In addition, concurrence from the applicable frequency 
coordinator must be obtained on frequencies designated for such a 
requirement. The coordinator's recommendation may include comments on 
technical factors such as power, antenna height and gain, terrain, and 
other factors which may serve to minimize potential interference. In 
addition:
    (2) On frequencies designated for coordination or concurrence by a 
specific frequency coordinator as specified in Secs. 90.20(c)(3) and 
90.35(b)(3), the applicable frequency coordinator shall provide a 
written supporting statement in instances in which coordination or 
concurrence is denied. The supporting statement shall contain 
sufficient detail to permit discernment of the technical basis for the 
denial of coordination or concurrence.
    (3) In instances where a frequency coordinator determines that an 
applicant's requested frequency or the most appropriate frequency is 
one designated for coordination by a specific frequency coordinator as 
specified in Secs. 90.20(c)(3) and 90.35(b)(3), that frequency 
coordinator may forward the application directly to the appropriate 
frequency coordinator. A frequency coordinator may only forward an 
application as specified above if consent is obtained from the 
applicant.
* * * * *
    8. Section 90.187 is amended by revising paragraphs (b)(2)(i) and 
the second sentence of (b)(2)(ii) to read as follows:


Sec. 90.187  Trunking in the bands between 150 and 512 MHz.

* * * * *
    (b) * * *
    (2) * * *
    (i) Stations that have assigned frequencies (base and mobile) that 
are 15 kHz or less removed from proposed stations that will operate 
with a 25 kHz channel bandwidth; stations that have assigned 
frequencies (base and mobile) that are 7.5 kHz or less removed from 
proposed stations that will operate with a 12.5 kHz bandwidth; or 
stations that have assigned frequencies (base and mobile) 3.75 kHz or 
less removed from proposed stations that will operate with a 6.25 kHz 
bandwidth; and
    (ii) * * * Alternatively, applicants may submit an engineering 
analysis based upon generally accepted engineering practices and 
standards that demonstrates that the service area of the trunked system 
does not overlap the service area of any existing station.
* * * * *
    Section 90.207 is amended by revising the last sentence in 
paragraph (l) to read as follows:


Sec. 90.207  Types of emissions.
