New Horizon Mine <br />2012 ARR Review <br />Annual Reporting, Permit <br />Revegetated Land Pasture Yields <br />Exhibit 2012 -11 depicts NH2 first cut yields. <br />Evaluated exhibit 2012 -11. PLEASE ADD AN ITEM TO THE LEGEND IN EXHIBIT 2012 -11 FOR PASTURE AREAS. THE ARR TEXT STATES THAT <br />page 2.05.4(2)(e) -74 <br />THE WEIGHTED AVERAGE FOR 1 CUTTING PRODUCTION FROM THE NH2 AREA WAS 1,472 IBS /AC - THIS DISAGREES WITH THE NUMBER <br />IN EXHIBIT 2012 - 11(1,562 IBS /AC). IT DOES NOT APPEAR FROM EXHIBIT 2012 -11 OR THE ARR REPORT THAT A 2ND CUTTING OCCURED, <br />HOWEVER, THE RECLAMATION MANAGEMENT TRACKING WORKSHEET- IRRIGATION FOR AUGUST 2012 INDICATES THAT SECOND <br />CUTTING OCCURRED BETWEEN 8/12/12 AND 9/15/12 WHEN THE IRRIGATION WAS SHUT OFF. ALSO, IN THE COMMENTS SECTION ON <br />THE WORKSHEET, IT APPEARS THAT ONLY "SOME' 2ND CUT DATA WERE COLLECTED. PLEASE PROVIDE THESE DATA IF COLLECTED. <br />? <br />Soil and Spoil Scarification <br />ARR Report indicates that prior to growth media soil replacement the final graded spoil was <br />This is consistent with wording/requirements in the Permit PR 6 MR 81.
