Shuey Subject: Craig Gravel, 112 Permit No. M 76-027 Inspection Report Mr. Shuey: In response to your Inspection Report of O1 August 2000 for our Craig Gravel Source Permit No. M 76-027 we wish to make the following statements. Reoon Item 1. in replacing the west boundary markers Mr. Olson found the marker signs (mounted on delineator posts) lying on the ground at the northwest and northeast corners of the reclaimed former stockpile/process area. Since the S/P azea has been reclaimed the landowner has been conducting agricultural operations thereon, that use of which is pan of the Reclamation Plan. Apparently he had removed the posts with the signs mounted on them to get them out of the way of his grass drilling and stone removal operations. We have temporarily replaced the marker posdsigns, until the area can be terminated from the permit area. We shall be mailing you some photos of the marked boundary. i CDUi~ lt:;ni ~ As l~iiii Illl)at alining Upefail UllJ, Life Uepil] u1 UJflU1C rC30UfCt Can only be estimated, particularly in deep deposits like the Craig source, where exploratory equipment cannot reach the bottom. As you know the bottom elevation of natural deposits tend to vary widely depending upon the depositional environment at that time. The mining plan had no intention of designating an absolute bottom elevation, but did intend to utilize all of the valuable resource. Obviously the reclamation cost analysis is in need of revision, based upon what is now known of the apparent depths of the gravel deposit. We are preparing a technical revision to address those changes. That T-R will also address the steep & deep high-wall mining technique used at the north boundazy of the permit area, and shall re-define the permit area boundaries, based upon recent accurate land surveys of those boundaries. Original permit boundaries were based upon aerial photographs, and assumptions concerning placement of existing fences. At that time areas of completed Nielsons. Inc. 22419 County Rd. G P.0.
