Per commitment made in item 7 (D) on page 3 of this fax, a statement will be <br />included in the Exhibit D -Mining Plan that requires a technical revision and an <br />inaease in bond to be processed at such time as the flood management designs <br />are approved by UD&FCD, and that no mining will occur within 400' of the <br />riverbank as determined by UD&FCD until such a technical revision is processed. <br />20. I think eve adequately discussed on June 1 the terms of low flow channel, existing <br />high banks, floodplain, and floodway areas. If further clarification is needed, 1 can <br />add it into the Exhibit G naztative and show a representative location of each area <br />on the Exhibit C-1 -Pre-Mining Map. <br />21. Tuttle Applegate will prepare further analysis and discussion of the possible <br />`mounding" and `shadow" affects of the slurry wall. A summary of this analysis <br />and discussion will be included in Exhibit G -Water Information. <br />22. Tuttle Applegate will prepare further characterization of the average depth to <br />groundwater, hydraulic gradient and/or flow direction, and expected seepage <br />velocity or flow rate. A summary of this further characterization will be included <br />in Exhibit G -Water Information. <br />23. In response to Mr. Weber's comments, we will include in Exhibit E -Reclamation <br />Plan Map a specific number of willow and cottonwood saplings that will be <br />planted in degraded stream bank areas and along the County's proposed trail <br />easement area. <br />24. We K~II provide representative soil cores on the western portions of the property. <br />Please understand, this data should be considered confidential information. <br />Where appropriate we will change the text throughout the application to be <br />consistent with this data. <br />25. Per item 12 on page 5 of this fax, a wetlands inventory is being completed along <br />with specific plans for the 404 permit to mitigate wetlands removal with <br />replacement wetlands and provide a cost estimate for the replacement, and <br />incorporate these plans into Exhibit E -Reclamation Plan. In Exhibit D -Mining <br />Plan, the statement will be added that no wetlands area identified in the inventory <br />will be disturbed until the 404 permit is issued. In both Exhibit E -Reclamation <br />Plan and in Exhibit L -Reclamation Cosis, the statement will be included that if <br />the approved 404 mitigation plan is substantially different from what is <br />incorporated into these plans, a technical revision will be submitted and processed <br />to incorporate the approved 404 permit mitigation plan. <br />6 <br />
