(a) Operations shall be conducted in accordance with an approved plan of operations, except as provided in paragraph (b) of this section and in § 228.4 (a), (b), and (e). A proposed plan of operation shall be submitted to the District Ranger, who shall promptly acknowledge receipt thereof to the operator. The authorized officer shall, within thirty (30) days of such receipt, analyze the proposal, considering the economics of the operation along with the other factors in determining the reasonableness of the requirements for surface resource protection, and;
(4) Notify the operator that the plan is being reviewed, but that more time, not to exceed an additional sixty (60) days, is necessary to complete such review, setting forth the reasons why additional time is needed: Provided, however, That days during which the area of operations is inaccessible for inspection shall not be included when computing the sixty (60) day period; or
(b) Pending final approval of the plan of operations, the authorized officer will approve such operations as may be necessary for timely compliance with the requirements of Federal and State laws, so long as such operations are conducted so as to minimize environmental impacts as prescribed by the authorized officer in accordance with the standards contained in § 228.8.
(c) A supplemental plan or plans of operations provided for in § 228.4(d) and a modification of an approved operating plan as provided for in § 228.4(e) shall be subject to approval by the authorized officer in the same manner as the initial plan of operations: Provided, however, That a modification of an approved plan of operations under § 228.4(e) shall be subject to approval by the immediate superior of the authorized officer in cases where it has been determined that a modification is required.
(d) In the provisions for review of operating plans, the Forest Service will arrange for consultation with appropriate agencies of the Department of the Interior with respect to significant technical questions concerning the character of unique geologic conditions and special exploration and development systems, techniques, and equipment, and with respect to mineral values, mineral resources, and mineral reserves. Further, the operator may request the Forest Service to arrange for similar consultations with appropriate agencies of the U.S. Department of the Interior for a review of operating plans.
