(c) A person may not employ or engage an individual in a position required to hold an MMC unless that individual maintains a current medical certificate. Medical certificates must be issued and will remain current for the following periods of time, unless otherwise noted on the certificate:

(1) After January 1, 2017, two years for individuals serving on vessels to which STCW applies unless the mariner is under the age of 18, in which case the maximum period of validity will be 1 year.

(2) Two years for individuals serving as a first-class pilot or those individuals serving as pilots on vessels of 1,600 GRT or more under §15.812 of this part.

(3) Five years for all other mariners.

(d) Each individual referred to in paragraph (a) of this section must hold an MMD or MMC that serves as identification, with an appropriate endorsement for the position in which the seaman serves, and the MMD or MMC, along with a valid medical certificate, must be presented to the master of the vessel at the time of employment or before signing Articles of Agreement.

(e) Each individual below the grades of officer and staff officer employed on any U.S. flag merchant vessel of 100 GRT or more must possess a valid MMD or MMC issued by the Coast Guard, except as noted below:

(1) Mariners on vessels navigating exclusively on rivers and lakes, except the Great Lakes, as defined in §10.107 of this subchapter.

(2) Mariners below the rank of officer employed on any non-self-propelled vessel, except seagoing barges and barges to which 46 U.S.C. chapter 37 applies.
