6.4.19 EXHIBIT S -Permanent Man-Made Structures <br />The mining operation will not adversely affect the stability of any significant, valuable or <br />permanent man-made structures located within two hundred (200) feet of the affected land. <br />The permanent man-made structures located within or adjacent to a line drawn two hundred (200) <br />feet from the affected land aze: <br />1. The Gurley Ditch, an irrigation ditch just east of the gravel pit and is crossed once by the <br />gravel pit access road. <br />2. The San Miguel Power Association 69 kV Transmission line that crosses the gravel pit <br />area. <br />3. Fences owned by Marilyn Allen. <br />4. Fences owned by Lila and Mazlyn Williams <br />5. Fences owned by Tom Farmer <br />6. A fence line owned by Dr. Michael DeJohn. <br />7. County Road 37.00 <br />8. McCallan Fence <br />All of these structures aze depicted on the mining plan map. <br />Damage agreements aze enclosed for items 1 through 4. An Engineering Evaluation is provided <br />for item 5 through 8. <br />The gravel pit is designed in accordance with design standazds supplied by San Miguel Power <br />Association for earthmoving adjacent to their power poles and vertical clearance required under <br />"Open supply conductors, over 750 V to 22kV: ungrounded guys exposed to 750 V to 22 kV" <br />where "Roads, streets, and other azeas subject to truck traffic" aze expected to occur.' <br />These standazds, as adjusted for elevation and current, require the operator to maintain vertical <br />clearance (as measured from the ground) of 22.8 feet or 23 feet. Additionally these standazds <br />require the operator to leave a 20 foot diameter of undisturbed earth around the power poles of a <br />transmission line, with slopes no greater than 2h:ly. <br />'Taken from PART 2.
