Lightering activities, or STS Operations, must remain suspended until corrective action has been completed.

(g) If any vessel not involved in the lightering operation, STS Operation, or support activities approaches within 100 meters of vessels engaged in lightering or STS Operation, the vessel engaged in lightering or STS Operation shall warn the approaching vessel by sounding a loud hailer, ship's whistle, or any other appropriate means.

(h) Only a lightering tender, a supply boat, or a crew boat, equipped with a spark arrestor on its exhaust, or a tank vessel providing bunkers, may moor alongside a vessel engaged in lightering operations or STS Operations.
