ORDER OF MODIFICATION
Adopted: August 24, 2010 Released: August 24, 2010
By the Deputy Chief, Policy Division, Public Safety and Homeland Security Bureau:
I. INTRODUCTION 
1. By this Order of Modification, we modify the license of the State of Washington 
(Washington) for Private Land Mobile Radio (PLMR) station WPKU684 to reduce the Effective 
Radiated Power (ERP) of the base station, authorized under the referenced call sign, as detailed below.  
We take this action in furtherance of ensuring compliance with international obligations and the 
Commission’s rules.
II. BACKGROUND  
2. Washington is licensed to operate 800 MHz PLMR station WPKU684 at a fixed location in 
the State of Washington.  Because Station WPKU684 operates in the 800 MHz band and is located 
within 140 kilometers of the border with Canada, it is subject to the provisions of the bilateral annex 
(Arrangement F) with Canada, which specifies the conditions under which 800 MHz PLMR stations may 
operate along the border.1 Under Arrangement F, the ERP of stations in the border region is limited 
based on the height of the transmitting antenna.  These power and antenna height limits are also reflected 
in Section 90.619(c)(3) of the Commission’s rules.2  
3. On May 21, 2010, the Public Safety and Homeland Security Bureau, acting under delegated 
authority, issued Washington an Order Proposing Modification (OPM) which proposed reducing the 
ERP of the base station licensed under call sign WPKU684 from 528 watts to 500 watts.3 The reduction 
in ERP proposed in the OPM would bring this base station into compliance with the ERP limits of

the Use Along the US-Canada Border of the Band 806-890 MHz (Jan. 1994, addendum, Dec. 1994) (Arrangement 
F).  See also Arrangement Between the Dept. of Communications of Canada and the FCC of the United States 
Concerning the Use Along the US-Canada Border of the Bands 821-824 MHz and 866-869 MHz (Sep. 1990, 
addendum, Dec. 1994).

Section 90.619(c)(2) of the Commission’s rules and Arrangement F.4 Washington was afforded 30 days 
to protest the OPM.5
III. DISCUSSION  
4. Because Washington failed to protest the proposed modifications of its license within 30 
days,6 it is deemed to have consented to the proposed modification.7 Based on the record in this matter, 
we hereby modify the authorization for PLMR Station WPKU684, as proposed in the OPM, to ensure 
compliance with international obligations and Commission rules.  See Attachment I.
5. ACCORDINGLY, IT IS ORDERED, pursuant to Sections 4(i) and 316 of the 
Communications Act of 1934, as amended, 47 U.S.C. §§ 154(i), 316, and Sections 1.87 and 90.619(c)(2) 
of the Commission's Rules, 47 C.F.R. §§ 1.87, 90.619(c)(2) that the licenses for Private Land Mobile 
Radio Service Station WPKU684, held by the State of Washington, IS HEREBY MODIFIED by 
reducing the Effective Radiated Power at base station location 1 from 528 watts to 500 watts as indicated 
in Attachment I to comply with Section 90.619(c)(2) of the Commission’s rules and Arrangement F.
6. IT IS FURTHER ORDERED, that the Chief of the Licensing Branch, Policy Division, Public 
Safety and Homeland Security Bureau, SHALL CAUSE the records of the Commission’s Universal 
Licensing System for Private Land Mobile Radio Service Station WPKU684 be modified consistent with 
this Order of Modification.
7. IT IS FURTHER ORDERED that this Order of Modification shall be sent by certified mail, 
return receipt requested, to State of Washington, ATTN Clallam Correction CRT Steve Hans., 1830
