By the Chief, Policy and Licensing Division, Public Safety and Homeland Security Bureau:
1. On April 25, 2012, in conjunction with the Wireless Telecommunications Bureau, we 
waived, on our own motion, the January 1, 2013 deadline for private land mobile radio (PLMR) licensees

Communications Act of 1934, as amended, 47 U.S.C. §§ 154(i) and 303(r), and Section 1.925 of the 
Commission’s Rules, 47 C.F.R. § 1.925, that the Requests for Waiver of Sections 90.203(j)(10) and 
90.209(b)(5) of the Commission’s Rules, 47 C.F.R. §§ 90.203(j)(10), 90.209(b)(5), filed by the Maryland 
Department of Transportation on March 8, 2012 and Ocean County, New Jersey on December 22, 2011 
ARE DISMISSED AS MOOT.
