Those statewide licenses only apply to trunked systems run by the state itself, and only cover the 700 band. Counties or other agencies would be required to license 700 MHz systems the same as any other license, including providing detailed site info.
Each state is allocated an exclusive 2.4 MHz block of frequencies in the band (192 12.5 kHz frequencies), which they can basically do what they want with as far as building out sites. They are supposed to have certain frequencies allocated for usage in specific counties, but I haven't yet seen a state hold to that. They basically just work with the regional planning committees and other states to mitigate interference at state borders.
