Mr. Thomas Schreiner - •~ Re: River Valley Resource, M-200/-090 December 9, 100! Ppge3of4~ same mix that is being proposed for use in the 404 application. It will consist of the grasses listed 'in Exhibit E on page 10. The final mix application rates-and species will be provided to the Division following approval of the 404 permit and prior to the relocation of the Suttle Ditch. ,Flows from the Swale area draining from south to north through the proposed project site will be diverted around the mining operation (please see response to Comment 17). The diversion will begin where the Swale currenfly crosses the southern project boundary and will. end where the drainage now crosses the northern project boundary. The diversion ditch will be sized and constructed to safely convey existing flows and potential dewatering flows around. the project site while minimizing excessive erosion. -Once directed back into the drainage area north of the proposed site, the estimated mine dewatering flows (0.3 to 0.7 cfs) would not be expected to adversely affect drainage within the Swale area. 6.4.7 EXHIBIT G -Water Information 19. Previously submitted Exhibit C-1, C-2 and Exhibit F show a potential new location for both the Suttle Ditch and the Little River. As discussed previously, the operator commits to relocating ~ ~4. the ditches in the same configuration and flow capacity as currently exists. y~.~irr,+r"` 6.4.12 EXHIBIT L -Reclamation Costs 20. The Swale area/Little River will need to be relocated during the early course of the mining. As the relocation will take place early, the total amount of disturbance to the site will be less than the maximum shown in .Exhibit L. There will be sufficient bond in the early phases of the mining to relocate and revegetate the Swale area/Little River. There will be approximately 2000 linear feet bf relocated Swale area. As some of the relocated Swale is part of the 404 permit application, the operator will provide the Division with the design and projected construction costs after the 404 permit is approved. .6.4.14 EXHIBIT N -Source of Leal RiEht to Enter n~~~Ul ~,p~} 21 On March 11, 2001, More Family Ranches, LLC and Western Mobile Northern, Inc. (Lafarge Corporation) entered into a lease to allow Lafarge Corporation to mine the property and More to receive royalties. Paragraph 1 of the Memorandum of Sand and Gravel Miriing Lease (Exhibit, N) plainly states that Lafarge Corporation may occupy the property and perform all the necessary activities to produce sand and gravel products. Both parties correctly executed the Lease and Memo of Lease.
