They point this out and, of course, indicate that the material will <br />require cover by a more suitable growth medium. <br />cc: Sandy Brown <br />COLORADO <br />DIVISION OF <br />MIN&RALS <br />GEOLOGY <br />RECLANATION•NIN ING <br />SAFETY•SCIEN CE <br />Bill Owens <br />Governor <br />Greg E.
