(c) Mobile and portable stations are 

limited to 2 watts EIRP and the 

equipment must employ a means for 

limiting power to the minimum 

necessary for successful 

communications. 

(d) Power measurements for 

transmissions by stations authorized 

under this section may be made either 

in accordance with a Commissionapproved average power technique or in 

compliance with paragraph (e) of this 

section. In both instances, equipment 

employed must be authorized in 

accordance with the provisions of 

§ 24.51. In measuring transmissions in 

this band using an average power 

technique, the peak-to-average ratio 

(PAR) of the transmission may not 

exceed 13 dB. 

(e) Peak transmit power must be 

measured over any interval of 

continuous transmission using 

instrumentation calibrated in terms of 

an rms-equivalent voltage. The 

measurement results shall be properly 

adjusted for any instrument limitations, 

such as detector response times, limited 

resolution bandwidth capability when 

compared to the emission bandwidth, 

sensitivity, etc., so as to obtain a true 

peak measurement for the emission in 

question over the full bandwidth of the 

channel. 

Note to § 24.232: Height above average 

terrain (HAAT) is to be calculated using the 

method set forth in § 24.53 of this part.

■ 4. Revise § 27.50(d) to read as follows: 

§ 27.50 Power and antenna height limits. 

* * * * * 

(d) The following power and antenna 

height requirements apply to stations 

transmitting in the 1710–1755 MHz and 

2110–2155 MHz bands: 

(1) The power of each fixed or base 

station transmitting in the 2110–2155 

MHz band and located in any county 

with population density of 100 or fewer 

persons per square mile, based upon the 

most recently available population 

statistics from the Bureau of the Census, 

is limited to: 

(A) an equivalent isotropically 

radiated power (EIRP) of 3280 watts 

when transmitting with an emission 

bandwidth of 1 MHz or less; 

(B) an EIRP of 3280 watts/MHz when 

transmitting with an emission 

bandwidth greater than 1 MHz. 

(2) The power of each fixed or base 

station transmitting in the 2110–2155 

MHz band and situated in any 

geographic location other than that 

described in paragraph (d)(1) is limited 

to: 

(A) an equivalent isotropically 

radiated power (EIRP) of 1640 watts 

when transmitting with an emission 

bandwidth of 1 MHz or less; 

(B) an EIRP of 1640 watts/MHz when 

transmitting with an emission 

bandwidth greater than 1 MHz. 

(3) A licensee operating a base or 

fixed station in the 2110–2155 MHz 

band utilizing a power greater than 1640 

watts EIRP and greater than 1640 watts/ 

MHz EIRP must coordinate such 

operations in advance with all 

Government and non-Government 

satellite entities in the 2025–2110 MHz 

band. Operations with power greater 

than 1640 watts EIRP and greater than 

1640 watts/MHz EIRP must be 

coordinated in advance with the 

following licensees authorized to 

operate within 120 kilometers (75 miles) 

of the base or fixed station operating in 

this band: all Broadband Radio Service 

(BRS) licensees authorized under part 

27 in the 2155–2160 MHz band and all 

advanced wireless services (AWS) 

licensees authorized to operate on 

adjacent frequency blocks in the 2110–

2155 MHz band. 

(4) Fixed, mobile, and portable (handheld) stations operating in the 1710–

1755 MHz band are limited to 1 watt 

EIRP. Fixed stations operating in this 

band are limited to a maximum antenna 

height of 10 meters above ground. 

Mobile and portable stations operating 

in this band must employ a means for 

limiting power to the minimum 

necessary for successful 

communications. 

(5) Equipment employed must be 

authorized in accordance with the 

provisions of § 24.51. Power 

measurements for transmissions by 

stations authorized under this section 

may be made either in accordance with 

a Commission-approved average power 

technique or in compliance with 

paragraph (d)(6) of this section. In 

measuring transmissions in this band 

using an average power technique, the 

peak-to-average ratio (PAR) of the 

transmission may not exceed 13 dB. 

(6) Peak transmit power must be 

measured over any interval of 

continuous transmission using 

instrumentation calibrated in terms of 

an rms-equivalent voltage. The 

measurement results shall be properly 

adjusted for any instrument limitations, 

such as detector response times, limited 

resolution bandwidth capability when 

compared to the emission bandwidth, 

sensitivity, etc., so as to obtain a true 

peak measurement for the emission in 

question over the full bandwidth of the 

channel.

Fisheries of the Exclusive Economic 

Zone Off Alaska; Pacific Ocean Perch 

by Vessels in the Bering Sea and

Fishery in the Eastern Aleutian District 

of the Bering Sea and Aleutian Islands 

Management Area 

AGENCY: National Marine Fisheries 

Service (NMFS), National Oceanic and 

Atmospheric Administration (NOAA), 

Commerce. 

ACTION: Temporary rule; closure. 

SUMMARY: NMFS is prohibiting directed 

fishing for Pacific ocean perch by 

vessels participating in the Bering Sea 

and Aleutian Islands (BSAI) trawl 


ebenthall on PRODPC60 with RULES
Federal Register / Vol. 73, No. 86 / Friday, May 2, 2008 / Rules and Regulations 24185 

limited access fishery in the Eastern 

Aleutian District of the BSAI. This 

action is necessary to prevent exceeding 

the 2008 Pacific ocean perch allowable 

catch (TAC) allocated to vessels 

participating in the BSAI trawl limited 

access fishery in the Eastern Aleutian 

District of the BSAI. 

DATES: Effective 1200 hrs, Alaska local 

time (A.l.t.), April 29, 2008, through 

2400 hrs, A.l.t., December 31, 2008. 

FOR FURTHER INFORMATION CONTACT: 

Jennifer Hogan, 907–586–7228. 

SUPPLEMENTARY INFORMATION: NMFS 

manages the groundfish fishery in the 

BSAI exclusive economic zone 

according to the Fishery Management 

Plan for Groundfish of the Bering Sea 

and Aleutian Islands Management Area 

(FMP) prepared by the North Pacific 

Fishery Management Council under 

authority of the Magnuson-Stevens 

Fishery Conservation and Management 

Act. Regulations governing fishing by 

U.S. vessels in accordance with the FMP 

appear at subpart H of 50 CFR part 600 

and 50 CFR part 679. 

The 2008 Pacific ocean perch TAC 

allocated as a directed fishing allowance 

to vessels participating in the BSAI 

trawl limited access fishery in the 

Eastern Aleutian District of the BSAI is 

214 metric tons (mt) as established by 

the 2008 and 2009 final harvest 

specifications for groundfish in the 

BSAI (73 FR 10160, February 26, 2008). 

In accordance with § 679.20(d)(1)(iii), 

the Administrator, Alaska Region, 

NMFS (Regional Administrator), has 

determined that the 2008 Pacific ocean 

perch TAC allocated to vessels 

participating in the BSAI trawl limited 

access fishery in the Eastern Aleutian 

District of the BSAI has been reached. 

Consequently, NMFS is prohibiting 

directed fishing for Pacific ocean perch 

by vessels participating in the BSAI 

trawl limited access fishery in the 

Eastern Aleutian District of the BSAI. 

After the effective date of this closure 

the maximum retainable amounts at 

§ 679.20(e) and (f) apply at any time 

during a trip. 

Classification 

This action responds to the best 

available information recently obtained 

from the fishery. The Assistant 

Administrator for Fisheries, NOAA, 

(AA), finds good cause to waive the 

requirement to provide prior notice and 

opportunity for public comment 

pursuant to the authority set forth at 5 

U.S.C. 553(b)(B) as such requirement is 

impracticable and contrary to the public 

interest. This requirement is 

impracticable and contrary to the public 

interest as it would prevent NMFS from 

responding to the most recent fisheries 

data in a timely fashion and would 

delay the closure of Pacific ocean perch 

by vessels participating in the BSAI 

trawl limited access fishery in the 

Eastern Aleutian District of the BSAI. 

NMFS was unable to publish a notice 

providing time for public comment 

because the most recent, relevant data 

only became available as of April 28, 

2008. 

The AA also finds good cause to 

waive the 30-day delay in the effective 

date of this action under 5 U.S.C. 

553(d)(3). This finding is based upon 

the reasons provided above for waiver of 

prior notice and opportunity for public 

comment. 

This action is required by § 679.20 

and § 679.91 and is exempt from review 

under Executive Order 12866. 

Authority: 16 U.S.C. 1801 et seq. 

Dated: April 29, 2008.

Acting Director, Office of Sustainable 

Fisheries, National Marine Fisheries Service.
