Lont <br /> Division Dvecmr <br />1645 Court Place, Ste 309 <br />Denver, CO 80202 <br />Mr. Lewicki: <br />The Division has completed review of technical revision #16 (TR-16), Revision of Revegetation <br />Standazds, for the Rimrock mine. Please respond to the following question as soon as possible. <br />Please define how the upper limit of the diversity standazd will be applied, should <br />reclamation success sampling indicate an individual species is present in excess of 60% <br />relative cover. For example, if future bond release sampling indicates that the vegetative <br />community is comprised of 61% Side oats grams, 13% western wheatgrass, 2% <br />American vetch, 2.3% green needlegrass, and the balance 21.7% comprised of various <br />species all under 3% relative cover, how would Rimrock Coal Company apply the 60% <br />maximum exclusion to the diversity standazd? Furthermore, what measures would <br />Rimrock take, should relative cover for single species exceed the upper limit? <br />Sincerely, / <br />Kent Gorham <br />Environmental Protection Specialist <br />cc: Dan Hernandez, DMG <br />
