HWY 141 and the utility poles may be within 200 feet. b. Per Rule 6.3.5(2)(c) -Update legend to include all features depicted on map.Blue line is labeled as midway but not described as to what it is,road,foot trail, etc.? c. Depict any other phases (midway project area) that interact with this phase. 29. Midway Project Area Map a. Per Rule 6.3.5(2)(c) - Clarify and label what are pre-existing trails/roads and what features will be created to support future phases. Update legend to include all features depicted on map.Blue line is labeled as midway but not described as to what it is,road,foot trail, etc.? b. Per Rule 6.3.5(2)(d) - Indicate direction(s) of mining. c. Depict any other phases (ridgetop and Siberia project area) that interact with this phase. 30. Connector Project Area - Are all aspects of the connector project area described on the Ridgetop Map? If not please create a map for the connector project area and address Rule 6.3.5(2). 31. Purple Pipe Project Area - Modify the Ridgetop Map to address the interactions between these two project areas or create a new map addressing Rule 6.3.5(2) and the prospecting of the Purple Pipe Project Area. 32. Unnamed Project Area map a. This appears to be a duplicate of the Project Areas map with a slightly different legend. b. Include a map to support the mining plan per Rule 6.3.5(2). Alternatively as previously stated this plan and map can later be submitted through a technical revision and for the time being just add in the acreage to the permit. 33. Reclamation Maps Per Rule 6.3.5(2)(a) - Show the gradient of all reclaimed slopes (horizontal:vertical) sufficient to describe the post mine topography; a. From your map it is unclear if each bench is 20 feet high by 30 feet deep or if the total slope with four interstitial benches is 20 x 30 feet. b. Will vertical slopes remain (i.e.benches)? Reclamation plan states a 2H: 1V slope but a 1.5H: 1V slope is depicted and no benches are mentioned. c. Provide the post mine topography for all project areas not just the midway project area. d. One map states"re-seed entire clearing after grading to 1%". 1%is nearly flat is this a typo or will there intentionally be a flat pad area created? If so the reclamation plan for the ridgetop project area also needs to state this. 34. Reclamation Maps Per Rule 6.3.5(2) (b) - Indicate where vegetation will not be established and the general area(s) for shrub or tree planting; Page 4 of 5
