(a) The OHA will grant a petition that seeks an adjustment from a DOE rule, regulation or order under the authority of 42 U.S.C. 7194 only if it determines that doing so will alleviate or prevent serious hardship, gross inequity or unfair distribution of burdens.

(b) Except as provided by program, statute, rule, regulation, or DOE delegation of authority, the OHA will grant any other petition filed under this part upon a showing that the DOE acted arbitrarily, capriciously, or in violation of a law, rule, regulation, or delegation with respect to the final disposition of DOE that is the subject of the petition.

(c) Petitions shall be decided in a manner that is, to the extent possible, consistent with the disposition of previous petitions of the same kind.
