According to the FCC ULS system (ULS License - Public Safety Pool, Conventional License - WQA839 - CAMBRIA, COUNTY OF
), 453.2 is on a tower at "2KM INT TOWER RD & SR 2009, NEW GERMANY, PA CAMBRIA County" while 453.3 is on a tower at ".3KM INT W CUMBERLAND & ST BENEDICTSTS, CARROLLTOWN, PA CAMBRIA County"
They also list those frequencies on this license (ULS License - Public Safety Pool, Conventional License - WQHM852 - CAMBRIA, COUNTY OF
) with additional sites (FB2 would be the repeater site). Since this second license has the narrow-band emission types, it may be the one in use, but they could use either (or even both) depending on what they're doing on those frequencies.
Please note that with the second license, 453.2 is listed as a fixed base and a mobile frequency (not a repeater) so it may have changed to simplex or simply as a backup simplex channel if the repeater (from license 1 above) goes down. Hard to tell simply by looking at the licenses.
