Peabody Sage Creek Mine <br />SL -3 Phase 111 Bond Release Request <br />July 2014 <br />acreage) for current annual herbaceous production derived from sampling in the approved PSCM <br />sagebrush and mountain brush reference areas. The weighting contribution is mountain brush <br />83% and sagebrush 17 %. Based on the production sampling an allowable herbaceous production <br />value is determined by excluding noxious weeds and allowing no more than 10% relative <br />production of annual /biennial weeds. The allowable herbaceous production standard is <br />determined by weight averaging the values based on the percent contribution of the mountain <br />brush and sagebrush types. <br />Table 4. 2010 and 2011 Data and Sample Adequacy Summary for Total and Allowable <br />Herbaceous Production (pounds /acre), Phase III BRB PSCM -1. <br />Table 5. 2010 and 2011 Data and Sample Adequacy Summary for Total and Allowable <br />;Herbaceous Production (pounds /acre) in the Mountain Brush and Sagebrush Reference <br />Areas for the Phase III BRB PSCM -1 Herbaceous Production Performance Standard. <br />Vegetation Type <br />Total <br />Allowable <br />s <br />N <br />Nj. <br />t <br />Vegetation Type <br />Herbaceous <br />Herbaceous <br />s <br />N <br />Nm;n <br />t <br />Sagebrush 2010 <br />Production <br />Production <br />556.7 <br />30 <br />70 <br />1.311 <br />Phase III Bond Release <br />835.1 <br />835.1 <br />556.7 <br />30 <br />77 <br />1.311 <br />Sagebrush 2011 <br />1973.5 <br />1973.5 <br />1006.4 <br />30 <br />45 <br />1.311 <br />BRB PSCM -1 2010 <br />Phase III Bond Release <br />2815.8 <br />2815.8 <br />1356.1 <br />35 <br />40 <br />1.311 <br />BRB PSCM -1 2011 <br />Table 5. 2010 and 2011 Data and Sample Adequacy Summary for Total and Allowable <br />;Herbaceous Production (pounds /acre) in the Mountain Brush and Sagebrush Reference <br />Areas for the Phase III BRB PSCM -1 Herbaceous Production Performance Standard. <br />Vegetation Type <br />Total <br />Herbaceous <br />Production <br />Allowable <br />Herbaceous <br />Production <br />s <br />N <br />Nj. <br />t <br />Mountain Brush 2010 <br />483.6 <br />483.6 <br />356.9 <br />30 <br />94 <br />1.311 <br />Sagebrush 2010 <br />874.3 <br />874.3 <br />556.7 <br />30 <br />70 <br />1.311 <br />Mountain Brush 2011 <br />835.1 <br />835.1 <br />556.7 <br />30 <br />77 <br />1.311 <br />Sagebrush 2011 <br />1234.8 <br />1234.8 <br />417.5 <br />30 <br />20 <br />1.311 <br />11 <br />
