(a) The DOE may issue an order granting a stay if the DOE determines that an applicant has made a compelling showing that it would incur serious and irreparable injury unless immediate stay relief is granted pending determination of an application for review pursuant to this subpart. An application for a stay shall be labeled as such on the application and on the outside of the envelope in which the application is transmitted, and shall be in writing and signed by the firm filing the application. It shall include a description of the proceeding incident to which the stay is being sought and of the facts and circumstances which support the applicant's claim that it will incur irreparable injury unless immediate stay relief is granted. The applicant shall comply with the general filing requirements stated in 10 CFR 205.9 in addition to the requirements stated in this section. The DOE on its own initiative may also issue an order granting a stay upon a finding that a firm will incur irreparable injury if such an order is not granted.(b) An order granting a stay shall expire by its terms within such time after issuance, not to exceed 30 days as the DOE specifies in the order, except that it shall expire automatically 5 days following its issuance if the applicant fails within that period to file an application for review unless within that period the DOE for good cause shown, extends the time during which the applicant may file an application for review.(c) The order granting or denying a stay is not an order of the DOE subject to administrative review.
