(a) The Commission will forward rate or service inquiries to the Postal Service for investigation. The Postal Service will, within 45 days of receipt of such inquiry, advise the Commission in writing, with a copy to the inquiring party, of its resolution of the inquiry or its refusal or inability to do so.

(b) The Commission will monitor all rate or service inquiries to determine if Commission action under § 3023.12 is appropriate.

(c) Where there are clear indications from the Postal Service's report or from other communications between the parties that the inquiry has been resolved, the Commission may, in its discretion, consider such proceeding to be resolved, without response to the inquiring party.
