INTEROFFICE MEMORANDUM <br /> TO: ROB ZUBER <br /> FROM: JANET BINNS <br /> SUBJECT: KEENESBURG MINE RN8 VEGETATION REVIEW <br /> DATE: 12/20/2021 <br /> CC: <br /> I have reviewed CEC's application for Permit Renewal No. 8,RN8, Section 2.05.4;Revegetation, <br /> Vegetation Sampling and Revegetation Success standards. I compared the RN8 text with the <br /> previously approved permit text in Laser fiche. I also review the RN8 submitted text changes in <br /> accordance with the Coal regulations and Guidelines. <br /> CEC has reformatted the pagination of this section and revised some of the text. The <br /> repagination is appropriate and all the previously approved sections are included in the revised <br /> format. <br /> CEC has also removed some of the excessive verbiage in the Revegetation Plan, Interim <br /> Vegetation Monitoring, and Determining Final Revegetation Success sections of the permit. This <br /> proposed revision of text clears up confusing text,yet does not alter the previously approved <br /> permit commitments, sampling methodology,or reclamation success standards. The revised text <br /> is appropriate. <br /> No changes were made to the approved reclamation seed mix. However, CEC is now including <br /> the seed mix as a list within the permit text, and no longer including the seed mix as a table. No <br /> information is lost with this change. <br /> One text change that the Division recommends CEC correct, <br /> On page 15 of the RN08 revised page: in the Species Composition paragraph,please <br /> remove "a"from the final sentence, so it reads; "Any perennial grass species may be used <br /> in the calculation of species composition except for those species defined as noxious by <br /> the Colorado Department of Agriculture." <br /> I have no other concerns. <br />
