V ~`- • (Page 2) MINE ID # OR PROSPECTING ID #: _M-2000-118 INSPECTION DATE: 10/7/00 INSPECTOR'S INITIALS: JCS OBSERVATIONS This inspection was pre-operational in nature brought about by the submittal of a 112 application by D.G. Huskin Construction. The applicant was represented during the inspection by Rick Pounds and consultants Joe Gagliano and Joe Gagliano Jr. The required on-site notice of the application had been posted near the entrance to the proposed permit area. In company with the applicant's representative, boundary markers for the proposed 112 permit area were located. The 112 permit area will contain the permit area of an existing 111 operation, i.e. Permit M- 2000-015. The area excavated during operations conducted under the 111 permit will apparently be expanded under the 112 permit, when issued. The initial adequacy review of the 112 application was faxed and mailed to the consultants on September 29, 2000, i.e. prior to this inspection. As a result of this inspection and discussions of the adequacy review that took place on-site, certain additional adequacy issues were identified and changes in the proposed operation were indicated. From file application, 2 fences and 1 access road could be identified as being permanent man-made structures within 200 feet of the area to be affected by the operation. On site inspection revealed that there is a power line situated along the access road which also lies within 200 feet of the area to be affected by the operation. All four structures should be listed and the owners identified under a revised Exhibit C narrative as required by Rule 6.4.3(g). The requirements of Exhibit S, i.e. Rule 6.4.19 must also be satisfied in regard to these structures. The adequacy review included the Division's estimate of the cost of reclaiming the site. Assumptions made for the Division's estimate included 20 acres of unreclaimed, excavated area; a maximum of 35 acres of mining related disturbance; over 3600 feet of vertical highwall 25 feet high; 4.5 feet of overburden; 0.5 feet of topsoil; and 15 acres of stockpiles, processing area, roads, etc. As a result of the discussion of the Division's estimate made on site, it is the Division's understanding that the applicant will now agree that no more than 10 acres of open pit and no more than 1000 feet of vertical, unreduced highwall will exist at any time. It is also the Division's understanding, from descriptions made during the inspection, that overburden and topsoil will be stripped prior to excavating the gravel deposit, that the overburden would be stockpiled along two margins of the area to be excavated and the topsoil on a third. The remaining pit margin would be a ramp down into the pit. Once the mining had reached the limits of the area to be excavated, e.g. a 10 acre area, mining would be down to an 3:1 slope to avoid reducing the highwall by backfill. Reclamation would then consist of "shingling" in the overburden on the 3:1 pit margins and spreading the topsoil on the replaced overburden, pit floor and the ramped fourth margin of the pit. The size of the stockpile/processing area will remain at 15 acres. Based on this understanding, which must be confirmed in the applicant's response to the Division's adequacy review, the Division will re-estimate a cost of reclamation which should reduce the amount of financial warranty required of the applicant. In addition to the above, agreement on various other adequacy issues were reached on-site. The more significant of these include 1) a commitment to maintain 300 feet of separation of the affected area and the Huerfano River and 2) to maintain boundary markers adequate to demonstrate that no more than 10 acres of open pit and no more that 35 acres of affected area exist at any time. A permit has not been issued for the proposed operation; there are no compliance problems at this point.
