The remainder of this document is divided into logical sections. Section 2.0 provides results by mine <br />area (East Pit, West Pit, Section 16, and Fire Areas) by revegetated unit, and by year of seeding (1998, <br />2001, and 2003). Each unit and resulting data /mapping is separately presented along with a brief <br />discussion of any pertinent observations and/or recommendations. A description of field methods utilized <br />in 2005 is presented as Appendix AA, and raw data tables and charts are presented in Appendix AB. In <br />this manner, only the most salient information is provided in the main body of this document. Acreages <br />presented in this 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). Precipitation in the project area was above-average <br />when compared with the five-year average for the 2004 / 2005 growing season (September 2004 through <br />August 2005). However, this five-year average is potentially below the actual long-term average for the <br />mine given that 2001 through 2004 are recognized as below-average precipitation years region wide <br />(drought years). For example, the nearest official weather station (Craig 45W) received only 44% of its <br />average precipitation in 2001, 61% in 2002, 86% in 2003, and 83% in 2004. The average precipitation <br />for 2005 was above-average (117%) in Craig. Given this analysis the long-term average precipitation at <br />the Colowyo mine is most likely in the 19 inch range as opposed to the recent four-year average of 16.5 <br />inches. Therefore, precipitation during the 2004 / 2005 growing season (22.84 inches) was likely three <br />• inches above average as opposed to six inches above. <br />I~ <br />Kennecott Energy Co. / Colowyo Mine Page 2 Revegetation Monitoring - 2005 <br />
