33 CFR 138.70 - Renewal of Certificates.
(a) The operator of a vessel required to have a Certificate under this subpart must submit a written or E-COFR request for renewal of the Certificate to the NPFC at least 21 days, but not earlier than 90 days, before the expiration date of the Certificate. A letter may be used for this purpose. The request for renewal must comply in all other respects with the requirements in § 138.60 concerning Applications. The Director, NPFC, may waive this 21-day requirement for good cause shown.
(b) The operator must identify in the request for renewal any changes which have occurred since the original Application for a Certificate was filed, and must set forth the correct information in full.
