I checked Columbia and surrounding counties in the FCC database and the only thing I see licensed there are low band frequencies. They're listed below.
In the southern tier, Tioga, Broome, Chenango, Cortland, Chemung, Steuben, & Tompkins counties they moved to P25 a few years ago. When I no longer heard them on the Low VHF frequencies I created a file for the BCD396T that contained all of the frequencies assigned to NYSEG in the entire state. That's how I located them. I'll attach that usd file and I also extracted just the frequencies to a text file. That should spare other's all of the searching.
