USCG Exam PracticeMMC application and renewal — 46 CFR Subchapter B
A mariner's MMC expired 8 months ago and has not been renewed. Which statement is correct regarding the credential?
- A. The credential is permanently invalid and the mariner must apply as an original applicant
- ✓ The credential may still be renewed because it is within the 12-month administrative grace periodCorrect
- C. The credential may be used for service because it is within the grace period
- D. The credential can only be renewed if the mariner presents evidence of sea service within the past 5 years
Why B is correct
46 CFR §10.227(h) allows a credential to be renewed up to 12 months after expiration. However, 46 CFR §10.205(c) and §10.227(h) make clear that the credential is not valid for use after its expiration date, even within the grace period. Eight months falls within the 12-month window, so renewal is still available.
