27 C.F.R. § 771.35
No license or permit shall be revoked or denied renewal unless, prior to the institution of proceedings, facts or conduct warranting such action shall have been called to the attention of the licensee or permittee by the Director of Industry Operations in writing in a contemplated notice, and the licensee or permittee shall have been accorded an opportunity to demonstrate or achieve compliance with all lawful requirements as set forth in section 9(b) of the Administrative Procedure Act. In cases in which the Director of Industry Operations alleges in his contemplated notice, with supporting reasons, willful violations or that the public interest requires otherwise, this section does not apply and the issuance of a contemplated notice is unnecessary.
