• The remainder of this document is divided into logipl sections. Section 2.0 provides results by mine <br />area (East Pit, West Pit, Section 16, and Fre Area) by revegetated unit, and by year of seeding (1996, <br />1999, 2001, and 2002}, 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 2003 is presented as Appendix AA, and raw data tables and charts are presented in Appends A8. In <br />this manner, only the most salient information is provided in the main body of this document. It should <br />also be noted that acreages presented in this document are approximate based on Cedar Creek's <br />mapping software, although these values are most likely very close to actual value. Acreage values for <br />which Colowyo is legally responsible are dependent upon thane values determined by Colowyo's <br />engineering and/or permitting deparbnent. <br />Precipitation data presented on Table P and Chart P (following Map 1) are the average of two <br />weather stations at the Colowyo Mine (SCN16 and WSTPT). Precipitation in the project area was above <br />the three-year average for most of the 2002 / 2003 growing season (September 2002 through August <br />2003). However, this three-year averege is potentially far below the actual long-term average for the <br />mine given that both 2001 and 2002 are recognized as below-average precipitation years region wide <br />(drought years). For example, the nearest official weather station (Craig 4SW) received only 45% of its <br />averege precipitation in 2001 and 60% in 2002. In addition, precipitation during the 2002 / 2003 <br />• growl+ng season at the Craig weather station was somewhat below average (41%).. Given this analysis <br />the long-term average precipitation at the Colowyo mine is most likely in the 18 to 20 inch range as <br />opposed to the recent three-year drought average of 14.5 inches. Therefore, precipitation during the <br />2002 / 2003 growing season was most likely slightly below or ck>se to average. <br /> <br />Kenneeon Energy Co. r Cdowyo lnne Page 2 Revegeragon AAonitoring -2003 <br />
