Status message

There is 1 rule appearing in the Federal Register for 46 CFR 10. View below or at eCFR (GPOAccess)
§ 10.203 Requirement to hold a TWIC and a merchant mariner credential.
(a) Any mariner required to hold a license, MMD, COR, and/or an STCW endorsement by a regulation in 33 CFR chapter I or 46 CFR chapter I must hold an MMC. A mariner may continue to serve under the authority of and within any restriction on their license, MMD, COR, and/or STCW endorsement until the first renewal or upgrade of that credential, but not later than April 15, 2014.
(b) Failure to obtain or hold a valid TWIC serves as a basis for the denial of an application for an original, renewal, new endorsement, duplicate, or raise of grade of a mariner's credential and may serve as a basis for suspension and revocation under 46 U.S.C. 7702 and 7703.
(c) An MMC, license, MMD, COR, or STCW endorsement must be retained by the mariner to whom it was issued and, while valid, must be produced to verify qualifications when requested by an authorized official as identified in 33 CFR 101.515(d). Posting of the officer endorsement may be necessary as required in 46 U.S.C. 7110.
(d) Although an MMD and an MMC serve as certificates of identification, a TWIC must be retained by the mariner to whom it was issued and, while valid, serves as the mariner's primary identification document. The TWIC must be produced to verify identity when required by an authorized official as identified in 33 CFR 101.515(d).
