The remainder of this document is divided into logical sections. Section 2.0 provides results by mine <br />area (East Pit, Section 16, and West Pit) by revegetated unit. Each unit and resulting data/mapping is <br />separately presented along with a brief discussion of any pertinent observations and/or <br />recommendations. The East Pit unit, EP042, was sampled out of the normal monitoring sequence to <br />facilitate an examination of the annual grass population to determine if remedial action is needed. The <br />information gained during this examination is presented separately in Section 2.6 and has not been <br />included in the summary results along with the other monitoring units. Section 2.7 presents results of <br />data collected from the CSU Shrub Plots in East Pit. Section 3.0 presents pertinent conclusions and/or <br />recommendations. A description of field methods utilized in 2010 is presented as Appendix AA and raw <br />data tables and supporting tables and charts are presented in Appendix AB. In this manner, only the <br />most salient information is provided in the main body of this document. Acreages presented in this <br />document are determined by Colowyo's engineering and/or permitting department. <br />Precipitation data presented on Table P and Chart P (following Map 1) is the average of two weather <br />stations at the Colowyo Mine (SCN16 and WSTPT from 2001-2008 and SCN16 and SCN34 in 2009 and <br />2010). The West Pit station was moved to South Taylor in 2009, therefore SCN34, which is located near <br />the Colowyo offices, was substituted for the analysis of precipitation at the mine. This site is located at <br />approximately the same elevation as the old West Pit Station. Precipitation in the project area for the <br />2009/2010 growing season (September 2009 through August 2010) was determined to be 67% of <br />average when compared to the ten-year average. However, this ten-year average is potentially below <br />the actual long-term average for the mine given that 2001 through 2004 are recognized as below- <br />average precipitation years region wide (drought years). For example, the nearest official weather <br />station (Craig 4SW) received only 44% of its average precipitation in 2001, 61% in 2002, 86% in 2003, <br />and 83% in 2004. Given this analysis the long-term average precipitation at the Colowyo mine is most <br />likely in the 19-inch range as opposed to the recent ten-year average of 17.0 inches. Therefore, <br />precipitation during the 2009/2010 growing season (11.5 inches) was most likely well below average. <br />Cedar Creek Associates, Inc. 2 Colowyo Mine <br />2010 Revegetation Monitoring Report
