MANAGEMENT <br />On behalf of Bowie Resources, LLC, enclosed is an application for a technical revision to revise the <br />revegetation success standard that will be used for Phase III bond release at the West Mine, Run -of -Mine <br />area, and East Mine. <br />Attached is a discussion from Cedar Creek Associates (CCA) detailing the proposed changes to the <br />revegetation success standards. These proposed changes are based upon data collected during the 2013 <br />and 2016 field surveys and document the pattern for revegetation based on the approved seed mixes. <br />CCA determined the initial success standards were not representative of actual revegetation <br />composition. CCA compares the species composition to the approved post -mining land use and <br />proposes a revised revegetation success criteria which lowers both the woody plant density standard <br />and revises the diversity standard. <br />Please feel free to contact me if you have any questions. <br />Sincerely, <br />C�./�� dg"QP4.� <br />06 Tamme Bishop, P.E. <br />Project Engineer <br />Attachments: Volume I, pages 74a & 75 <br />Volume 9A, Cedar Creek Associates "Phase III Bond Release Success Standards" <br />Volume 9A, Harner & Associates, July 1986, page 6 <br />Cc: Basil Bear <br />
