(c) The band 482-488 MHz (TV Channel 16) is available for use by eligibles in the Public Safety Radio Pool in the following areas: New York City; Nassau, Suffolk, and Westchester counties in New York State; and Bergen County, New Jersey. All part 90 rules shall apply to said operations, except that:

(1) *Location of stations.* Base stations shall be located in the areas specified in this [paragraph (c)](/on/2024-09-20/title-47/section-90.303#p-90.303(c)). Mobile stations may operate throughout the areas specified in this [paragraph (c)](/on/2024-09-20/title-47/section-90.303#p-90.303(c)) and may additionally operate in areas not specified in this [paragraph (c)](/on/2024-09-20/title-47/section-90.303#p-90.303(c)) provided that the distance from the Empire State Building (40° 44′ 54.4′′ N, 73° 59′ 8.4′′ W) does not exceed 48 kilometers (30 miles).

(2) *Protection criteria.* In order to provide co-channel television protection, the following height and power restrictions are required:

(i) Except as specified in [paragraph (c)(2)(ii)](/on/2024-09-20/title-47/section-90.303#p-90.303(c)(2)(ii)) of this section, base stations shall be limited to a maximum effective radiated power (ERP) of 225 watts at an antenna height of 152.5 meters (500 feet) above average terrain (AAT). Adjustment of the permitted power will be allowed provided it is in accordance with the “169 kilometer Distance Separation” entries specified in Table B in [47 CFR 90.309(a)](/on/2024-09-20/title-47/section-90.309#p-90.309(a)) or the “LM/TV Separation 110 miles (177 km)” curve in Figure B in [47 CFR 90.309(b)](/on/2024-09-20/title-47/section-90.309#p-90.309(b)).

(ii) For base stations located west of the Hudson River, Kill Van Kull, and Arthur Kill, the maximum ERP and antenna height shall be limited to the entries specified in Table B in [47 CFR 90.309(a)](/on/2024-09-20/title-47/section-90.309#p-90.309(a)) or in Figure B in [47 CFR 90.309(b)](/on/2024-09-20/title-47/section-90.309#p-90.309(b)) for the actual separation distance between the base station and the transmitter site of WNEP-TV in Scranton, PA (41° 10′ 58.0′′ N, 75° 52′ 20.0′′ W).
