In Parma / Medina County / Ottawa County - The RadioReference Wiki I see Medina County and Ottawa County listed as "owners". I believe Parma "owns" the system and is letting Ottawa and Medina share the controller with Parma.
Also Medina County system frequencies are in the 700 MHz range not just 800 MHz for the system.
