A total of seven samples were collected at various sites located to the east of the <br />preparation plant pad. Composited samples were taken of highwall, fill, overburden, and mine portal <br />materials. The samples were analyzed by the Cooperative Extension Service soil laboratory on the CSU <br />~~ campus. The parameters for which samples were analyzed corresponded to those listed above, as <br />.. <br />routine, for the samples collected by Cedar Creek in July of 1994. Fertilizer recommendations were also <br />~ developed as a result of these analyses. <br />The results of these seven sampling programs were reviewed and analyzed for input into this report. <br />The endemic soil sample analyses provide data for a comparison of the characteristic of local soil materials <br />?~) <br />versus overburden materials proposed to be used as a surface cover. The results of the IME work provide <br />laboratory analysis results of direct importance to the assessment of the suitability of overburden materials <br />~~, <br />as a soil substitute. <br />,`3 <br /> <br />P'' <br />~.A <br />~e <br />21 <br />ri•'.. <br /> <br /> <br /> <br /> <br />h <br />5 <br />
