Are the following Orono State Police frequencies 42.120 and 42.140 valid frequencies?

I haven't heard any activity at all on these two frequencies. All of the other State Police frequencies come in great, and are often busy (such as 154.905 and 154.695) However with these two (42.120 and 42.140) That isn't the case, I haven't heard any such activity whatsoever, and it makes me wonder if these are still valid. Are these outdated frequencies? Or are they just for State Police emergencies or mutual aid backup? Any info on this would be very helpful.
