33 C.F.R. § 138.150 – Reporting requirements.

(a) Report changes of submitted information. When there is a change in any of the facts contained in an Application, a request for COFR renewal, evidence of financial responsibility, or other submission made under this subpart, the change must be reported, in writing, to the Director. The reports required by this section may be submitted with, but are in addition to, other submissions required by this subpart (for example, Applications, requests for COFR renewal, semi-annual and annual financial reports, Master Certificate reports).
(b) A 21-day prior reporting requirement of permanent vessel transfers and other changes requiring issuance of a new COFR. Current COFR Operators of vessels, and owners or operators of vessels not currently in U.S. navigable waters or the U.S. Exclusive Economic Zone, must report to the Director, and (if applicable) to the guarantor, the following information, no later than 21 business days before the new COFR is required:
1. (1) The number of the current COFR;
2. (2) The name of the covered vessel;
3. (3) The type of change planned;
4. (4) The date the change will take place;
5. (5) The reason for the change;
6. (6) For a vessel that will be located in U.S. navigable waters or U.S. Exclusive Economic Zone on the date the change is scheduled to take place, where the vessel will be located on that date (for example, name and location of port);
7. (7) For a vessel name change, the vessel's new legal name;
8. (8) For the planned transfer of a vessel to a new responsible party, and even if the transferee's intent is to scrap or otherwise dispose of the vessel, the name and contact information of the responsible party to whom the vessel is being transferred;
9. (9) For a change of COFR Operator, the name and contact information of the person who will replace the COFR Operator; and
10. (10) Any other changes in the information previously submitted to ensure the information on record at the NPFC is current.
(c) Three-day prior reporting of changes not requiring issuance of a new COFR. In addition to the prior reporting required by paragraph (b) of this section, the COFR Operator must report any change to information contained in a submission to the Director that does not require issuance of a new COFR, by no later than 3 business days before implementing the change, including, but not limited to: Changes to the U.S. agent for service of process (other than termination), a change of a non-operator vessel owner, new contact information, and changes in vessel particulars (for example, flag, measurement, type, and scheduled vessel scrapping).
(d) Reporting by guarantors. Each guarantor (or, if there are multiple guarantors, each lead guarantor) must give the Director 30 days notice before terminating a guaranty as provided in § 138.110(a)(3), explaining the reason for the intended termination, once known, or should have known, in the ordinary course of business.
(e) Enforcement; deadline exceptions. A failure to timely submit the reports required by this section may result in enforcement actions as provided in § 138.170. Exceptions to the reporting deadlines will only be granted as provided in § 138.60(e).
