Greetings,
If you are looking for the Pine Ridge Vol Fire Dept, It is actually dispatched on the Berkeley County South Fire/EMS Channel. 154.2500 (CT127.3). They are Company 2. Just Remember though, that listening to this channel you will hear all the other Volunteer Fire Depts and EMS in the South End of Berkeley County.
If need a list of the other fire companies, let me know
Hope this helps,
Wally
