I'm getting it as well and the talk group and rid's match Bates-Burg PD.
24851 - BLV FD 1 is still active and in the clear. The FD 1 and PD 1 talk groups for Lexington county are internal channels for agencies as most use the shared talkgroups except BLVPD,WCPD,CAPD/CAFD. 24852 is currently still a valid TG and in my agencies radio's as BLVPD MA and is programmed for clear no encryption. 24856 is a new TG and as stated is fully E. Currently my TG's for Bates-Burg Leesville are
24851 - D - BLV FD 1 (Internal)
24852 - D - BLV PD MA
24856 - DE - BLV PD Dispatch
