INTEROFFICE MEMORANDUM <br /> <br />TO: JIilI RURNELL <br />FROM: J,\NIi'1' RINNS <br />SUBJECT: 1f~\RR 1IIN RNOS ~ ~ 'IEW <br />DATE: 11 /25/2005 <br />CC: DAN 1-IERNANDI3'/. <br />1 have reviewed the Marr Mine permit for compliance with Rule: 4.15 and 3.02.2. <br />Text that discusses revegetation success is found in section 780.18(6) of the permit. There are two distinct <br />azeas associated with the Marr Mine with different sets of reclamation success standards. The first is the <br />Marr Mine consisting of the reclaimed 720 pit and Pit 1, facilities area, access roads, and sediment ponds. <br />The second area is the Marr loadout located in the town of Walden. The load out and mine site have been <br />reclaimed. Mine has applied for and received approval for phased bond release on several of the <br />reclaimed areas. For bond release purposes, the operator has divided the reclaimed mine into three blocks: <br />Reclaimed prior to 1986, 1995 reclamation, and 1996 reclamation. The reclamation success standazds <br />apply to each of the three blocks. <br />Reclamation Success standazds: <br />Mine site reclamation success standards: based on anacreage-weighted average of 4 reference areas <br />plus baseline information from one vegetation community. "Reference areas" will be taken to mean the 4- <br />acreage-weighted reference areas along with the data form the Salt Flat community. <br />Cover: The reclaimed area will achieve or exceed 90% of the cover measured on the reference areas. <br />Productivity: The reclaimed area will achieve or exceed 90% of the productivity measured on the <br />reference areas. <br />Woody stem density: 1500 stems per acre. <br />Diversity: The 4 dominant plant species will contribute no more than 83% relative cover combined. <br />No one species will contribute greater than 40% relative cover. At least one of the 4 dominant species <br />will be a shrub or a forb. <br />Load out reclamation success standards: Cover and productivity are compared to the load out reference <br />azea. <br />Cover: The reclaimed area will achieve or exceed 90% of the cover measured on the load out <br />reference area. <br />Productivity: The reclaimed area will achieve or exceed 90% of the productivity measured on the load <br />out reference azea. <br />Marr Mine, C-1980-006, RNS <br />
