,- <br />PRYDR MINE HAUL ROAD CERTIFICATION REPORT <br />Although I was not present during th• actual construction of the <br />haul road,YI was able to verify the necessary information to <br />complete a'report on the construction. <br />A summary of the important design specifications, each followed <br />by the relevant comments from the site inspection, is given <br />below. The design specifications are shown on the map entitled <br />"Pryor Mine Haul Road" of the Pryor Mine Permit. The map is <br />dated September 21, 1993 and was developed by J. F. Sato & <br />Associates. <br />1. ADEQUATE TOPSDIL AND VEGETATIDN REMOVAL <br />This could not be fully verified during the site inspection; <br />however, it was evident that in some areas the road was installed <br />on bedrock and there was no topsoil to salvage. Minor digging <br />below the road base showed no topsoil below, and the topsoil <br />stockpile appeared adequate to reclaim the entire disturbed area. <br />2. ROAD WIDTH <br />Specifications show a road width of 24 feet. Site inspection <br />revealed that the width from station 1 + 60 to 2 + 00 was <br />approximately 21.0 feet. The widening was subsequently performed <br />by mine personnel. <br />3. CUT AND FILL EMBANKMENT SLOPES <br />Specifications show a maximum of 3.0 H 1.0 V for any cut and <br />fill slopes. The road, as installed, contains only one minor cut <br />(3 to 4 feet high) and the slopes are less than the specification <br />noted above. <br />4. GRADE <br />Specifications show grades of between 3.3% and 7.7%. The site <br />inspection showed all sections of the road to be between these <br />limits. <br />5. COMPACTION <br />No specification given. Site inspection revealed that the road <br />base was adequately compacted and that the bedrock which was <br />immediately below the road base provided additional strength. <br />During operation of the mine, the road required little <br />maintenance and did not produce ruts or slumps. <br />
