According to the FCC that license expired almost 20 years ago. Are you close enough to hear them and verify that they are or are not on the same frequency? I am a county administrator on the east side of the state and can't change anything on that side of the state. I can research the license that they have if you verify by listening what they are using frequency wise.
Can't help you with verification of use, I'm only in the area a few times a year to visit the national forests and parks.
Being a county away, you may not be in a good location to hear these. They are identified in the RRDB as tactical use & licensed for mobile only. You would need the combination of a significant fire event that would warrant tactical channel use & also be close enough to the incident to hear mobile/handheld simplex traffic.
