Circumstances may require that these minimum per- sonnel levels be increased so the diving operations can be conducted safely. NOTES: (a) Diving Supervisor may fill requirement for Comms and Logs for scuba operations. (b) Each additional surface-supplied diver or tended scuba diver will require an additional tender. The number of surface-sup- plied divers may be increased as necessary to the extent that the air system can support them. (c) Scuba divers, except SPECWAR divers and divers involved in Limpet operations (see paragraph 6-4.5 and paragraph 7-8.2 for more information), must be surface tended if direct ascent to surface is not available, such as when diving under the bilge keel. Situations may require that a diver be tended by a second diver situated at the bilge keel . (d) The EOD Diving Officer may authorize a single untethered EOD diver when disarming live ordnance in an operational (non-training) situation. (e) Submarines that have only three qualified scuba divers assigned are authorized to conduct dives with a non-diver Com- missioned Officer acting as the Diving Supervisor. In all cases, submarines will endeavor to obtain the prerequisite number of qualified divers to support their mission. All other commands are to conduct all scuba diving operations with a minimum of four divers. (f) EOD Diving Officers are required for all EOD operations involving Render Safe Procedures (RSP). (g) Manning levels for Multi-place Underwater Egress Trainer Device 9D5, are contained in the NASTP SOP. Use of qualified non-divers as Comms and Logs is authorized. (h) Chase boat is required for scuba diving operations when conditions exist where the diver could be displaced from the dive site (i.e. bottom search in a strong current or a long-duration swim). (i) If the standby diver is deployed, the Diving Supervisor shall tend the standby diver. (j) Comms and Logs may serve as Console Operator. (k) Standby diver can be deployed as a working diver in accordance with paragraph 6-9.8.2. Figure 6-16.  Minimum Personnel Levels for Air Diving Stations.
