27 C.F.R. § 771.40
Whenever the Director of Industry Operations has reason to believe that an applicant for an original license or permit is not eligible to receive a license or permit under the provisions of § 555.49 of this chapter, the Director of Industry Operations shall issue a notice of denial on ATF Form 5400.11 (Notice of Denial of Application for License or Permit) (F 5400.11). The notice will set forth the matters of fact and law relied upon in determining that the application should be denied and will afford the applicant 15 days from the date of receipt of the notice in which to request a hearing to review the denial. If no request for a hearing is filed within that time, a copy of the application, marked "Disapproved," will be returned to the applicant.
