May Day and Idaho Mine Complex 112 (d) Permit Application <br />• Mill will be salvaged, scrapped or buried in underground workings as approved by CDRMS <br />• Roads will remain as permanent and not require reclamation <br />• Affected areas identified on Figure C-4 will be reclaimed in accordance with Exhibit D. <br />• The new access road will be removed and reclaimed. <br />6 4 5(2) (e) (iii) An outline of the sequence for each phase of reclamation <br />Reclamation will be conducted in the phases one through six as outlined in Table E-1 and Sections <br />6.4.5(2)(e)(i) and 6.4.5(2)(e)(ii). <br />6 4 5(2 (?fl Specifications on Reveg_etation Factors <br />6 4 5(2) (fl 6) Final Grading <br />The maximum graded slope will be 1.5:1. <br />6 4 5(2) (fl (ii) Seeding <br />One native grass seed mix is sufficient for all revegetation projects within the affected lands. Table E-2 <br />provides the grass seed mix recommended by the U.S. Department of Agriculture Natural Resources <br />(USDA) Natural Resource Conservation Service (NRCS) divisions. This seed mix provides a good native <br />cover crop to stabilize soil surfaces and start the initial successional process to the montane forest. Alter- <br />natively, a montane seed mix suitable to the Colorado Plateau area could be obtained from a reputable <br />local seed supply company such as Western Native Seed6. <br />Table E-2.

The USDA recommends <br />6.5 pounds pure live seed per acre for reclamation purposes. However, also according to the USDA, <br />broadcast seeding methods should be used on steep sites and the seeding rate is doubled for broadcast me- <br />thod. Therefore, the seeding rate will be doubled to 13.0 pure live seed pounds per acre when the seed is <br />broadcast. The most desirable time for seeding is very late fall so the anticipated seeding time will be on <br />or near October 15. Access by wildlife and people will be limited until new vegetation is established. <br />5 Recommendation from Valerie J. Lovett, NRCS sheet, supplied 3-Sep-2010. <br />6 Western Native Seed; P.O.
