I~~ • ~ Page 2 State of Colorado Mined Land Reclamation (ii) Exhibit C, page 2(d) mentions the reason the cement plant was excluded from affected land. This exclusion was approved by Mr. Schmieding after consultation with Mr. McCall. Portland cement is a separate manufactured product with cement plant equipment and buildings ex- cluded from affected land in several states with similar regulations. (iii) Exhibit D. Introduction mentions an average thick- ness of 35.4 feet of the lower Fort Hays limestone is quarried with 8 to 12 feet of the overlying Fort Hays. This 43 to 48 total feet of limestone has usually been quarried in one bench; however, a recent two-bench operation was initiated for quality control reasons. The quarry floor slopes about 25 feet per 1,000 feet to the southwest. The surface elevations as indicated by the 5-ft. interval topography shown on map pcc-1387 is primarily the erosional pattern of the limestone de- posit, with minor varying amounts of soil materials and gravels as generally located in Exhibit B (c), para- graph 3. The location and depths of these materials are not a matter of record other than the difference between surface and floor elevations at any given location. Limestone quality information is available from a few selected core drill holes for general estimation. Overall stripping ratio of the west quarry was calculated at about 1 to 1, but recent operation indicates this may approach 1.3 to 1. Bench depths vary according to the actual conditions encountered as the quarry ad- vances, amounts of cement types manufactured including factors mentioned in Exhibit D (e). Due to these fac- tors and the long range nature of the operation, only general information of bench depth and quarry advance can be given. The small (40,000 tons per year) amount of sandstone to be quarried will vary in depth of excavation up to about 8 feet, normally quarried to allow gravity drain- age of water from the excavation. II. Exhibit A - Legal Description Legal descriptions in Sections 8 and 9, references 10-acre tracts numbered 1 through 64 in each section in the same manner as sections within a township. For clarification purposes, these Section 8 and 9 lands can also be described as follows:
