(a) Reasons for amendments. A Certifying Officer may amend a certification. The Department retains the authority to amend a certification without a petition, where it has determined that an amendment is appropriate. Amendments must not extend the impact date more than 1 year prior to the petition date unless there is a statutory exception, as described in § 618.235(a)(1)(ii). Reasons for amendments include, but are not limited to:
(1) Identifying an ownership change affecting the applicable firm;
(2) Correcting technical errors; or
(3) Clarifying the identification of the worker group.
(b) Petition filing. Amendments must be requested through the regular petition process described in § 618.205.
(c) Notification of amendment. The Department will publish the amended certification in the Federal Register and on the Department's website. The Department will also notify the affected States and the State must notify any additional certified trade-affected workers, as required by § 618.820.
