Is there one map that shows all the approved culverts? Along the access road and the <br />sediment pond access roads, there are approved culverts that are NECC's responsibility <br />and have been designed for specific flows. On the ground, additional culverts have been <br />installed by a third party (oil and gas development) and are not NECC's responsibility for <br />maintenance. A map with all of the culverts on it, that defines which culverts are NECC's <br />responsibility and which are not has not been identified. This map would need to be <br />specific to the actual area of disturbance for the Jeff Canyon Surface mine. If one does <br />not already exist in the permit, NECC needs to provide a single map that provides this <br />information. <br />10. NECC is considering using topsoil substitute material for gully repair locations. The <br />permit currently does not describe use of alternate plant growth material. NECC needs to <br />describe this practice in the permit. In this description NECC needs to describe where the <br />substitute material would come from, and describe what soil chemical and structural <br />parameters the topsoil substitute will be tested for. Suggested parameters to demonstrate <br />topsoil suitability include; N, P, K, SAR, Electrical conductivity, Soil texture, and <br />Organic Matter. <br />NECC - The permit describes the use and testing of substitute topsoil material on pages <br />2.05 -56 and 2.05 -58. <br />11. Permit page 2.05 -63 states that, "contour furrows may be employed along the steeper <br />slopes of highwall reclamation areas." Several areas on the reclaimed slopes at the <br />Lorencito Canyon Mine continue to exhibit gully formation. NECC plans to conduct <br />gully repair on these slopes in 2012. The Division considers implementation of contour <br />furrows or straw bale dikes as approved in the permit appropriate to the repair efforts. <br />Please utilize approved erosion control methods in accordance with NECC's approved <br />reclamation plan. <br />12. Reclamation success criteria required 500 stems per acre of woody species on <br />approximately 10% of the approved disturbance area. This criterion applies to the post - <br />mining land use of Rangeland, and applies to the grassland community of the Jeff <br />Canyon surface mine. The currently permitted disturbance area for the Lorencito Canyon <br />Mine is 129.3 acres. 5.9 acres will be permanent roads. 123.4 acres have been reclaimed <br />(2011 ARR). Therefore, approximately 12 acres are required to be established shrub <br />plots, (permit page 2.05 -73) with 2 -3 shrub transplant areas established each successive <br />year of reclamation. Currently, 2012, there is one fenced shrub enclosure constructed on <br />
