The minimum annual rate is 50% of the average number of covered crewmembers unless the Coast Guard publishes a different rate (46 CFR 16.230). Random testing is for drugs; the Coast Guard MIS report counts drug tests only. Select at least once a quarter and notify people so they report immediately.
