(a) Before designation for hearing. Any application not designated for hearing may be dismissed without prejudice at any time upon request of the applicant. An applicant’s request for the return of an application that has been accepted for filing and consideration, but not designated for hearing, will be deemed a request for dismissal without prejudice. The Commission may dismiss an application without prejudice before it has been designated for hearing when the applicant fails to comply or justify noncompliance with Commission requests for additional information in connection with such application.

(b) After designation for hearing. A request to dismiss an application without prejudice after it has been designated for hearing shall be made by petition properly served upon all parties to the hearing and will be granted only for good cause shown. An application may be dismissed with prejudice after it has been designated for hearing when the applicant:

(1) Fails to comply with the requirements of § 1.221(c);

(2) Otherwise fails to prosecute his application; or

(3) Fails to comply or justify noncompliance with Commission requests for additional information in connection with such application.
