Any officer or agency authorized to issue any rule or regulation, or any order having the applicability and effect of a rule as defined in section

(4) of title
5, pursuant to this chapter shall provide for the making of such adjustments, consistent with the other purposes of this chapter, as may be necessary to prevent special hardship, inequity, or unfair distribution of burdens and shall, by rule, establish procedures which are available to any person for the purpose of seeking an interpretation, modification, rescission of, exception to, or exemption from, such rules, regulations, and orders. Such officer or agency shall, within ninety days after August 14, 1976, establish criteria and guidelines by which such special hardship, inequity, or unfair distribution of burdens shall be evaluated. Such officer or agency shall additionally insure that each decision on any application or petition requesting an adjustment shall specify the standards of hardship, inequity, or unfair distribution of burden by which any disposition was made, and the specific application of such standards to the facts contained in any such application or petition. If any person is aggrieved or adversely affected by a denial of a request for adjustment under the preceding sentences, he may request a review of such denial by the agency and may obtain judicial review in accordance with subsection (c) of this section when such a denial becomes final. The agency shall, by rule, establish appropriate procedures, including a hearing when requested, for review of a denial, and where deemed advisable by the agency, for considering other requests for action under this paragraph, except that no review of a denial under this subparagraph shall be controlled by the same officer denying the adjustment pursuant to this subparagraph.
