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 <br />hundred (200) feet from the affected land are: <br />1. The Gurley Ditch, an imgation ditch that defines the eastern boundary of the grave] pit and <br />is crossed twice by the gravel pit access road. <br />2. The San Miguel Power Association 69 kV Transmission line that crosses the gravel pit <br />azea. <br />3. Fences owned by Marilyn Allen <br />4. The Redvale Road, a county road. <br />All of these structures aze depicted on the Exhibit C-1 Pre-Mining Plan map. Damage agreements <br />are enclosed for items 1 through 3. The mining plan for the gravel pit has been designed to leave <br />200 foot buffers between the disturbance created by the pit and both the Redvale Road and the <br />privately owned headgates, listed below. These 200 foot buffers maybe further evaluated. <br />An agreement to install culverts and create ditch crossings for the access road to the Phase I of <br />the grave] pit is included in Exhibit N. <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.3 <br />These standards, as adjusted for elevation and cun•ent, require the operator to maintain vertical <br />cleazance (as measured from the ground) of 22.8 feet or 23 feet. Additionally these standards <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 />A Damage Agreement Between Louisiana Land and Gravel Company, LLC and San Miguel <br />Power Association, Inc. which provides a remedy for any damages done to the transmission line is <br />included in this Exhibit. <br />A Damage Agreement Between Louisiana Land and Gravel Company, LLC and the Farmer's <br />Water Development Company which provides for mine excavation within 50 of the centerline of <br />the ditch and also provides for stockpiling of material within 15-feet of the edge of the ditch is <br />included in this Exhibit. <br />'Taken from PART 2. SAFETY RULES FOR OVERHEAD LINES, Table 232-1, Titled <br />Vertical Clearance of Wires, Conductors, and Cables Above Ground, Roadway, Rail or Water <br />Surfaces. <br />S-1 <br />
