(2) Approval or denial. The application Form 3624 together with any supporting papers will be sent to the postal services center. (Pending a decision, bulk mailings subject to the minimum per piece charge may be handled in accordance with paragraph (c) of this section.) The postmaster at the postal services center will approve or deny the application. The application Form 3624 and any supporting papers will be returned with the decision to the postmaster where the application was filed for notification of the applicant.

(3) Appeal. The decision of the postmaster at the postal services center may be appealed by the applicant, in writing to the postmaster where the application was filed. The postmaster will forward the appeal through the postal services center to the Bureau of Operations, Classification and Special Services Division. The appeal must be accompanied by the original application and all supporting papers.

(c) Temporary mailings. Until final action is taken on the application, postage paid on the mailings may be at the special rates, provided the mailer deposits with the postmaster an amount sufficient to cover the additional postage at the higher rates. See § 24.1(b) (1) and (2). This deposit will be returned to the mailer if the application is approved. If the application is denied, the deposit will not be returned. The deposit will be converted into postage-due stamps, and the stamps canceled and given to the mailer if no appeal is made. If appeal is made, action concerning the deposit will be deferred.

(d) Revocation. The approval may be revoked if the authorization was given to an organization or association which was not qualified or which becomes unqualified. The postmaster who approved the application will notify the organization of the pending cancellation of the authorization and of the reasons for the cancellation. The organization will be allowed 10 days within which to file a written statement why the authorization should not be canceled. When no answer is filed, the postmaster will cancel the authorization. If an answer is filed, decision will be made by the Bureau of Operations, Classification and Special Services Division, whether the authorization shall be continued in effect. No

tice of the decision will be given the organization through the postmaster. [28 F.R. 1470, Feb. 15, 1963] Prior Amendments
