A Contractor may at any time apply in writing to the Regional Director for modification of recommendations or determinations deemed necessary because of changed conditions, emergency, or hardship. Upon receipt of such written application identifying the reason for such requested modification, the Regional Director shall arrange for consultation with the Contractor with the objective of making such modifications as he may deem appropriate under the then existing conditions. The Regional Director may initiate efforts for further consultation with any Contractor on his own motion with the objective of modifying previous recommendations and determinations, but in the event such modifications are made, the Contractor shall have the same opportunity to object and appeal as provided in §417.3 of this part for the initial recommendations and determinations. The Regional Director shall afford the fullest practicable opportunity for consultation with a Contractor when acting under this section. Each modification under this section shall be transmitted to the Contractor by letter.
