potential new impact would be the development of a spoil spring in the pit area No springs <br />or seeps have ever been noted in the ten years since the water monitoring was discontinued. <br />Pre-law mining activities in the immediate and surrounding areas are much more likely to <br />have affected the ground water system than any impact due to mining at the Rimrock Mine. <br />The likelihood for future ground water pollution is negligible <br />Revegetahon <br />Statistically valid. vegetation sampling was conducted by Division personnel in 2002. 2003. <br />and 2004 This information was compiled and provided to the applicant for use In this bond <br />release application. Detailed reports prepared by the D~ws~on ~n 2003 and 2004 are a part of <br />this application Data collected m 2002 indicated the site did not meet the required <br />standards due to severe drought conditions and these data were not submitted with this <br />application. However, a summary of the results of the three consecutive years of sampling is <br />shown m the table below. <br />Table B <br />No Shrub <br />2004 sampling 37 7% ' 921 Ibs/acre <br />Diversity Standard At least three perennial grass species, each contributing at <br />but not greater than 60% relative cover. At least one of these species will be a warm <br />'ass and at least one shall be a cool season grass. <br />2003 Soeaes Oiversi <br />Twenty-three plant species were encountered in the vegetation cover sampling (see Tabte 1). <br />Nine species measured greater than 3% and less than 60% relative cover No species were <br />present at greater than 60% relative cover. Of the nine species. five speaes were perennial coo! <br />season grasses. three were warm season perennial grasses, and one was a perennial forb.

Ot the eight speaes. four species were perennial cool <br />season grasses, two were warm season perennial grasses, one was a perennial forb. and one <br />was a biennial forb The perennial forb was field bindweed, which is included on the Colorado <br />State Noxious Weed list but is not included on the Las Animas County weed list. The reclaimed <br />plant community achieved the approved speaes diversely standard. <br />
