(a) An agency that seeks approval for a change to a publication that is approved for incorporation by reference must—

(1) Publish notice of the change in the *Federal Register* and amend the Code of Federal Regulations;

(2) Ensure that a copy of the amendment or revision is on file at the Office of the Federal Register; and

(3) Notify the Director of the Federal Register in writing that the change is being made.

(b) If a regulation containing an incorporation by reference fails to become effective or is removed from the Code of Federal Regulations, the agency must notify the Director of the Federal Register in writing of that fact within 5 working days of the occurrence.
