June 6, 2007 <br />Permit Section 780.23 Post-mining Land use =Rangeland. <br />On reclaimed areas Pre-1986, 1995, and 1996 reclamation success criteria have been achieved for cover, production. woody <br />plant density and species diversity. On the 1999 reclaimed area cover and productivity reclamation success criteria were <br />achieved. 2005 vegetation sampling data show that cover, productivity, woody plant density and species composition have <br />been achieved for the Tipple area. The Tipple was reclaimed in 1999 ,and is not yet eligible for Phase III bond release. <br />Page 21 of the 2005 Revegetation Monitoring report for the Marr Mine implies that all criteria for revegetation success have <br />been met for the 2005 sampling event. The 1999 reclaimed area does not meet Phase III liability timeframe, nor woody <br />plant density requirement or species composition criteria for Phase III success. <br />achives <br />2006 reference areas success? <br />Big sage %cover 35.13 <br />g/1/4 MZ 8.67 <br />Alkalai sage %cover 31 <br />g/1/4 MZ 5.71 <br />2006 sampling reclaimed areas <br />Pre-1986 %cover <br />g/1/4 MZ <br />wpd <br />sp comp <br />1995 %cover <br />g/1/4 MZ <br />wpd <br />sp.
