With respect to administrative appeals involving a technical determination made by the Natural Resources Conservation Service, the Farm Service Agency, by rule with the concurrence of the Natural Resources Conservation Service, shall establish procedures for obtaining review by the Natural Resources Conservation Service of the technical determinations involved. Such rules shall ensure that technical criteria established by the Natural Resources Conservation Service shall be used by the Farm Service Agency as the basis for any decisions regarding technical determinations. If no review is requested, the technical determination of the Natural Resources Conservation Service shall be the technical basis for any decision rendered by a county or area committee established under section 590h(b)(5) of title 16. If the committee requests a review by the Natural Resources Conservation Service of a wetlands determination of the Service, the Farm Service Agency shall consult with other Federal agencies whenever required by law or under a memorandum of agreement in existence on October 13, 1994.
