(1) Commence at least 30 minutes before the first SURTASS LFA sonar transmission;
(2) Continue between transmission pings; and
(3) Continue either for at least 15 minutes after completion of the SURTASS LFA sonar transmission exercise, or, if marine mammals are exhibiting unusual changes in behavioral patterns, for a period of time until behavior patterns return to normal or conditions prevent continued observations;
(c) Holders of Letters of Authorization for activities described in §216.180 are required to cooperate with the National Marine Fisheries Service and any other federal agency for monitoring the impacts of the activity on marine mammals.
