When a State agency learns, through its own reviews under section 2025 of this title or other reviews, or through other sources, that it has improperly denied, terminated, or underissued benefits to an eligible household, the State agency shall promptly restore any improperly denied benefits to the extent required by subsection (e)(11) and section 2023(b) of this title, and shall take other steps to prevent a recurrence of such errors where such error was caused by the application of State agency practices, rules or procedures inconsistent with the requirements of this chapter or with regulations or policies of the Secretary issued under the authority of this chapter.

The State agency (as defined in section 2012(s)(1) of this title) of each State desiring to participate in the supplemental nutrition assistance program shall submit for approval a plan of operation specifying the manner in which such program will be conducted within the State in every political subdivision. The Secretary may not, as a part of the approval process for a plan of operation, require a State to submit for prior approval by the Secretary the State agency instructions to staff, interpretations of existing policy, State agency methods of administration, forms used by the State agency, or any materials, documents, memoranda, bulletins, or other matter, unless the State determines that the materials, documents, memoranda, bulletins, or other matter alter or amend the State plan of operation or conflict with the rights and levels of benefits to which a household is entitled. In the case of all or part of an Indian reservation, the State agency as defined in section 2012(s)(1) of this title shall be responsible for conducting such program on such reservation unless the Secretary determines that the State agency (as defined in section 2012(s)(1) of this title) is failing, subsequent to August 31, 1964, properly to administer such program on such reservation in accordance with the purposes of this chapter and further determines that the State agency as defined in section 2012(s)(2) of this title is capable of effectively and efficiently conducting such program, in light of the distance of the reservation from State agency-operated certification and issuance centers, the previous experience of such tribal organization in the operation of programs authorized under the Indian Self-Determination Act (25 U.S.C. 450) ^[1] and similar Acts of Congress, the tribal organization’s management and fiscal capabilities, and the adequacy of measures taken by the tribal organization to ensure that there shall be no discrimination in the operation of the program on the basis of race, color, sex, or national origin, in which event such State agency shall be responsible for conducting such program and submitting for approval a plan of operation specifying the manner in which such program will be conducted. The Secretary, upon the request of a tribal organization, shall provide the designees of such organization with appropriate training and technical assistance to enable them to qualify as expeditiously as possible as a State agency pursuant to section 2012(s)(2) of this title. A State agency, as defined in section 2012(s)(1) of this title, before it submits its plan of operation to the Secretary for the administration of the supplemental nutrition assistance program on all or part of an Indian reservation, shall consult in good faith with the tribal organization about that portion of the State’s plan of operation pertaining to the implementation of the program for members of the tribe, and shall implement the program in a manner that is responsive to the needs of the Indians on the reservation as determined by ongoing consultation with the tribal organization.
