Where the Director of Industry Operations has not ascertained whether the licensee or permittee has willfully violated the Federal explosives laws and where he believes the matter has the potential to be settled informally, i.e., without formal administrative proceedings, he shall, in accordance with section 5(b) of the Administrative Procedure Act, prior to the issuance of a notice of revocation or denial of renewal, give the licensee or permittee a contemplated notice of such action and an opportunity to show why the license or permit should not be revoked or denied renewal. The notice should inform the licensee or permittee of the charges on which the notice would be based, if issued, and afford him a period of 15 days from the date of the notice, or such longer period as the Director of Industry Operations deems necessary, in which to submit proposals of settlement to the Director of Industry Operations. Where informal settlement is not reached promptly because of inaction by the applicant, licensee, or permittee or proposals are made for the purpose of delay, a notice shall be issued in accordance with § 771.42 or § 771.43, as appropriate. The issuance of a notice of contemplated action does not entitle the recipient to a hearing before an administrative law judge.
