.~ Mr. Robert Stack April 22, 1997-Red Canyon Appl. Page 5 20) Rule 6.4.8 requires the submittal of an updated Exhibit H, since the existing exhibit does not address the presence of the Mexican Spotted Owl. 21) Rule 6.4.9 requires you to submit an updated Exhibit I, since the existing exhibit only applies to the "old quarry area" and does not address the general type, thickness and distribution of soil nor the suitability of topsoil (or other material) for establishment and maintenance of plant growth over the rest of the proposed affected land. 22) Rule 6.4.12 states that reclamation costs will be determined upon approval of the amendment application. 23) Rule 6.4.13 requires you to provide a list of all the other permits and licenses necessary to conduct the proposed mining and reclamationoperation.

The power line on the west side of the existing permit is considered a manmade structure, so, therefore, you need to comply with the requirements of Exhibit S. 25) Rule 6.5(1). On asite-specific basis, an applicant shall be required to provide a geotechnical evaluation of all geologic hazards within or in the vicinity of the affected lands that may be de-stabilized or exacerbated by mining or reclamation activities. Specifically, the dolomite beds appear to be underlain by a layer of ` shale (at the granite-dolomite contact) that may act as a failure surface, if exposed to the elements and the toe of the dolomite layer is undercut by mining. A massive slide could occur, if the dolomite is not mined properly. 26) Rule 6.5(4). At sites where blasting is part of the proposed mining or reclamation plan, the applicant shall demonstrate, through appropriate blasting, vibration, geotechnical, and structural engineering analyses, that off-site areas will not be adversely affected by blasting. Please provide sufficient information to demonstrate that the air and ground vibration thresholds are well within the standards set by the Office of Surface Mining and the U. S. Bureau of Mines. Pursuant to Rule 1.8, your response will constitute an amendment to your application. If necessary, within five (5) working days after receiving the amendment filing, the Division shall set a new date for the consideration of the application.
