The responses are provided in the order in which they were received in your letter. 1) Over the past several years, the shrub standard has been changed twice to its current standard of 500 stems per acre. While text of the permit on page 65A had been changed, the corresponding page 11 in Appendix F was not revised and the diversity standard was not adjusted to retlect the change of shrub density. As a result, pages 65 and 65A of the permit text and pages 10 and 11 of Appendix F have been revised and are attached for your review and approval. Slurco is revising the diversity standard to read "Slurco will establish a reclaimed vegetation community with a minimum of sin (6) principal species, of which three (3) will be cool season grasses, two (2) will be shrubs, and one (1) will be a forb. Within the post mining community, the three principal cool season grasses will contribute 7 to 60 percent of the relative cover, the principal forb will contribute 1 to 35 percent of the relative cover, and there will be no cover requirement for the two shrub species." 2) All of the information concerning ponds on pages 116a through 116j was removed during the renewal process in 1992. Please update your copy of the permit as per the revised materials submitted and approved under that renewal. 3) The acreage and dates of revegetation areas will be updated in the 1996 Annual Reclamation Report which will be submitted in January ]997. 4) Revised pages 1 through 3 of the permit document are attached which update the following ownership and control information: Exrcmrve Director Jerry Koblitz M,~,,,,ri u.
