Page 4 of 8 <br />caused extensive damage to the 83rd Joint Venture mine site located east of the Iverson Mine and <br />involved the Boyd Freeman Ditch located adjacent to the Iverson site. <br />17. The Applicant intends to install a conveyor structure to transport material to the 35th Avenue site, File <br />No. M-1977-036, for processing. The conceptual drawings included in Exhibit C are not adequate. <br />Please provide additional information regarding the conveyor structure (i.e. composition, length, <br />width, height, foundations, etc.) and a specific plan for reclamation of the structures. <br />6.4.5 Exhibit E - Reclamation Plan <br />18. The Applicant states Russian Olives existing prior to mining will not be removed by Lafarge. Russian <br />Olives are a B List noxious weed and must be eradicated from the site. Please commit to eradicating <br />the existing Russian Olives at the site as part of the weed control program. <br />19. The Applicant states the availability of the proposed seed mixtures may dictate the need for variety <br />substitutions. Once approved by the Division, a revision to the seed mixture would require the <br />Operator to submit and get approval for a technical revision, per Rule 1.9, to alter the seed mixture. <br />6.4.7 Exhibit G - Water Information <br />20. The application states the landowners are responsible for supplying all of the water required for <br />augmentation during mining and after the mine has been reclaimed. The Applicant should be aware a <br />permanent augmentation plan will need to be in place prior to release of the permit when reclamation <br />is complete. <br />21. The application states the landowner will file a Temporary Substitute Supply plan to address any <br />depletions due to operations on the Iverson property. The Applicant should be aware that this plan <br />needs to be in place prior to exposure of groundwater. <br />22. Please commit to providing the Division a copy of the approved Temporary Substitute Water Supply <br />Plan for the site. <br />23. The Applicant states dry mining will occur at the site, and a rather limited extent of drawdown due to <br />the mine dewatering operation is projected beyond the Iverson property. The Division requests the <br />Applicant quantitatively define or predict the cone of depression expected for any areas to be <br />dewatered and dry mined. The cone of depression and assessment of other effects should define, at a <br />minimum, the horizontal and vertical extent of expected impacts. <br />24. The Applicant has installed eight (8) monitoring wells in the area of the Iverson Mine. Monitoring wells <br />are required to be permitted by the Office of State Engineer. Please provide proof of monitoring well <br />permits to the Division. <br />4
