It's a contracted service. There are several tanker bases that are stood up around the state during wildfire season. The closest one to you would be Bedford. They also use Hazleton and Moshannon. There are fixed wing tankers and also some helicopters on contract for fire work, too. I don't know how many helibases there are right now. In the past, there has been one at Mount Pocono.
I think last year there were three tankers and one helo...probably the same this year, too. One plane at Bedford, Moshannon, and Hazleton and one helo at Mount Pocono. Maybe somebody else can chime in to confirm.
