Williams/Illinois CN-01 Adequacy Letter <br /> Page 3 of S <br /> August 11,2014 <br /> d. The overhead power line located within 200 feet of the southeast corner of the <br /> proposed site. <br /> 6.4.4 Exhibit D - Mining Plan <br /> 9. Please state if the Applicant intends to operate the site continuously or if the Division should <br /> consider the site an "intermittent operation" as defined in C.R.S 34-32.5-103(11)(b). <br /> 10. The Applicant states in the proposed Mining Plan, no more than 10 acres of land will be <br /> exposed at any given time. The Division considers all land affected by mining activities as <br /> disturbed acreage until the land is fully reclaimed and released by the Division. Since the <br /> current mining operation has disturbed 9.90 acres, the Division recommends the maximum <br /> allowed disturbance acreage be set at 14.98 to include the current mining area and Stage 1 <br /> of the proposed mining plan, at minimum. <br /> 11. During the pre-operational inspection, the Applicant discussed marking the boundaries of <br /> the next two mining stages as mining progresses. Please revise the Mining Plan to include <br /> the commitment to mark the next two stages ahead of the current mining stage as mining <br /> progresses at the site. <br /> 6.4.5 Exhibit E - Reclamation Plan <br /> 12. The Applicant states reclamation work will begin in the pit area during and after each stage is <br /> mined. An area of approximately 5 acres will be in reclamation during mining of each stage so <br /> that no more than 10 acres of land will be disturbed at any given time during the life of the <br /> 112 permit. As noted above, The Division considers all land affected by mining activities as <br /> disturbed acreage until the land is fully reclaimed and released by the Division. Since the <br /> current mining operation has disturbed 9.90 acres, the Division recommends the maximum <br /> allowed disturbance acreage be set at 14.98 to include the current mining area and Stage 1 <br /> of the proposed mining plan. <br /> 6.4.6 Exhibit F - Reclamation Plan Map <br /> 13. Please revise the Reclamation Plan Map to depict the expected physical appearance of the <br /> area of the affected land. The map must show the proposed topography of the area with <br /> contour lines of sufficient detail to portray the direction and rate of slope of all reclaimed <br /> land. <br /> 6.4.7 Exhibit G -Water Information <br /> 14. Please provide an estimate of the project water requirements including flow rates and annual <br /> volumes for the development, mining and reclamation phases of the project. <br />
