Dave, this is what I found:
Erie County multi agency tactical swat task force
4295 S. Buffalo St., Orchard Park
This is the address for the Town & Village of Orchard Park, NY PD/FD dispatch are located here.
The Erie County Sheriff Dept., at one time had a large presence at Chestnut Ridge Park.
I think they still dispatch from there. Not 100% sure, been away 20 years.
My guess is the Buffalo St address is for a station licensed to OPPD so they can communicate with the Sheriff's Dept. on that freq. I would have to search on that freq or multi-agency task force to see if there any licensed to the PD in Hamburg, Kenmore or Lancaster, NY etc.
