portal and ventilation shaft development, will be used for the construction of <br />the mine facilities bench. The Division believes that this is an acceptable <br />discussion. The Division does have a question regarding the possible waste <br />from the crushing and screening plant. Although there is not a processing <br />plant at the site, a crushing and screening plant will create some form of <br />refuse. The refuse will be in the form of either rocks or off-spec coal. There <br />will need to be some plan in place for dealing with this waste product. Please <br />discuss how the Northfield Mine plans on dealing with the waste that will be <br />created by the crushing and screening plant. <br />23. There are no storage areas listed in the list of facilities in Section 2.05.3. It is <br />the opinion of the Division that the Northfield Mine will have at least one <br />storage area and probably at least one bone-yard at the facilities area. The <br />Division requests that the operator discuss the need (or lack thereof) for <br />these storage areas. If these storage areas are needed, please add them to <br />the list of facilities in Section 2.05.3 and add them to the appropriate map. In <br />the discussion of these storage areas (if required) please include a <br />description of the materials to be stored and the methods of reclamation. <br />Section 2.05.4 -Reclamation Plan <br />24. There is a typographical error on the second line of the first paragraph of <br />Page 2.05.4-1. The second sentence, that begins ..."operation is an <br />significant..." is in error. Please change the word "an" to "a". Please <br />resubmit the updated page. <br />25. Page 2.05.4-4 discusses Facilities Removal. Again, as in question 4 above, <br />Northfield states that demolition debris that is not salvaged will be buried on <br />site. Please note that while the burial of demolition debris does not a <br />certificate of designation (CD) from the CDPHE, both county and landowner <br />approvals are required. Although the commencement of final reclamation is <br />many years in the future, the Division requests that Northfield include a <br />statement in the text stating that all necessary county and landowner <br />approvals will be in place prior to burying any demolition debris on the site. <br />26. Page 2.05.4-6 discusses the Topsoil Removal, Storage and Redistribution <br />Plan. Again, as in question 18 above, there appears to be a discrepancy in <br />the volume of topsoil available for replacement. Please take a very close <br />look at this and provide a detailed discussion of how the volume in the topsoil <br />balance was derived. Additionally, please include a table for the topsoil <br />balance. <br />27. Pages 2.05.4-11 and 2.05.4-12 discuss the Sealing or Management of Mine <br />Openings and Boreholes. The discussion of the sealing of boreholes <br />appears to be adequate. The Division, however, requests that Northfield <br />
