(1) For the purposes of this section, “military security zones” are specific portion/s within any of the restricted areas identified in this section that are defined by the safety vessels accompanying each training exercise. The mission of the safety vessels is to maximize safety conditions for both military and civilian personnel during exercises conducted within the restricted area by intercepting any waterbased activity occurring within the active military security zone/s and offering navigational advice to ensure the activity remains clear of the exercise.

(2) All areas identified in this section have the potential to be active at any time. The normal/routine activation of any area will be noticed to the public via a General Local Notice to Mariners. Activation of any area for significant exercises and training events will be noticed, in advance and during the event, to the public via Notice to Mariners and Broadcast Notice to Mariners.
