To mitigate the impact caused by the partial lapse in appropriations and shutdown of
National Maritime Center (NMC) operations, the following actions are being taken:
• Merchant Mariner Credentials (MMC) (National Endorsements only) that expire
between December 22, 2018, and January 31, 2019, are extended as valid until March
31, 2019. Print the attached letter and carry it with your credential.
• Additional Information (AI) letters, sent to mariners, that expire in December 2018 or
January 2019 are extended to March 31, 2019.
• Approval to Test (ATT) letters and mariner training course certificates that expire in
the months of December 2018 or January 2019 are extended until March 31, 2019.
• For mariners whose 90-day testing cycles were interrupted by Regional Exam Center
(REC) closures (starting on December 24, 2018), the days the RECs were closed will
not count against the 90-day period. REC appointment calendars will be re-opened
immediately once appropriations are restored.
The NMC understands the partial shutdown may affect our industry customers and
stakeholders and we apologize for any potential inconvenience.
