Talkgroup 10864 - ID'ed as '1F - Emergency'.
Talkgroup 25040 - 'Plant', 'Lab', 'Security'. Seems to be a security channel at least primarily. Units affiliating with it do not seem to use any other talkgroups. Security (gate) calls lab for authorization to let delivery folks in, with things like caustics, FedEx deliveries.

Talkgroup 10864 - ID'ed as '1F - Emergency'.

SDUSD. When the emergency button on their radios is pressed the radio jumps to this TG.
