(b) Requests for Regional review must include:
(4) A concise statement of the objections to the State decision.
The request must be filed by registered mail, return receipt requested, within thirty days of the date of the State decision or within a reasonable time if the State fails to respond in writing to the request for review.
(c) The Region shall determine whether the State's review is comparable to a dispute decision official's (DDO) review pursuant to 2 CFR part 1500, subpart E. If the State's review is comparable, Regional review of the State's decision will be conducted by the Regional Administrator. If the State's review is not comparable, the DDO will review the State's decision and issue a written decision. Review of either a Regional Administrator or DDO decision may be requested pursuant to 2 CFR part 1500, subpart E.
