June 14, 2011 C-2009-087/Peabody Sage Creek Mine JDM <br /> <br />Typical white top patch observed in BRB. <br />- White top patches were observed in the following locations with the largest patches observed along the western <br />facing slope of the SIIPM-6 drainage and should be managed to aid in the eradication of the species within the <br />bond release area. <br />revegetated area 99-1 f <br />revegetated area 03-1n <br />revegetated area 97-1b <br />revegetated area 03-1dd <br />revegetated 98-1e <br />revegetated area 03-1k <br />- Houndstounge rosettes were observed along SIIPM-16 and SIIPM6 in addition to the reclaimed haulroad <br />corridors of 03-1a, 03-lb, 98-If, and 02-1b that will need to managed. The majority of haul road corridors and <br />areas utilized for facilities are managed for noxious and invasive weeds on an as-need basis according to the Sage <br />Creek Mine weed management plan. <br />Based on the Division's guidelines for the management of noxious weeds, one of two criteria is used to determine <br />a infestation of noxious weeds is occurring; (1) noxious weeds exceeds three percent of relative cover in a <br />revegetated stand and (2) a patch of noxious weeds exceeds 25% relative cover and occupies an area larger than <br />100 square feet on a disturbed area. Based on this inspection, though noxious weeds were observed and noted, the <br />noxious weeds do not appear to meet the criteria of an infestation. A review of the revegetation evaluation <br />submitted with SL1 will help determine the actual percentage of noxious weeds identified through vegetation <br />sampling. <br />TOPSOIL - Rule 4.0611 ?Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; <br />Redistribution 4.06.4: <br />Topsoil depths were not verified during this inspection as depths were measured previously. Records of topsoil <br />depths are available at the Division offices and at the Sage Creek Mine offices. No evidence of inadequate topsoil <br />redistribution was observed during this inspection. <br />Number of Partial Inspection this Fiscal Year: 9 <br />Number of Complete Inspections this Fiscal Year: 4 <br />Page 4 of 5
