Long Dwision Director Re: Ophir Lode, File No. M-2001-063, 110(2) Permit Application, Second Adequacy Review Letter Dear Mr. Giesy, have reviewed your packet of adequacy response materials, and fmd that it satisfied most of the Division's concerns about the application named above. I still have a few questions, which appear in the paragraphs below. Yesterday, I spoke by phone with Barry Tollefson and Julie Coleman-Fike, both of BLM, about the ne~v material submitted in this application. Some of their concerns are echoed in my questions below, but concerns of theirs which do not fall within the Division's jurisdiction are not included in this letter. Again, I have arranged them according to the exhibits to which they pertain; their numbers, however, do not refer to those in my August 20, 2001, letter. Items in my former letter which are not included herein are considered adequate. Exhibit A -Location Map (Rule 6.3.1) 1. The new map submitted is correct except that its scale should read: "1:24,000." I have manually corrected it, and another one need not be submitted. Exhibit B -Site Description (Rule 6.3.21 2. You have named the two surface classes designated for the none location on the soils map, RO and RS, but have not provided any additional material descriptions. Lf description information exists, please provide it; if none exists in the soil survey, please state such. Exhibit C - Minine Plan (Rule 6 3 3J 3. The existing waste rock which will be removed and placed on the BLM-managed portion of the access road should be characterized before its removal from the permitted area. Prior to any removal activity, please provide a brief description of the rock, such as range of sizes, volume needed, color or degree of apparent mineralization, whether the rock .vas surficial or deeply buried in the dump, etc. I remember that the dump rock was not very mineralized, but please try to limit extraction to non-mineralized rock if possible. (Our staff geochemist visited the site last fall and noted minor amounts of galena, pyrite, sphalerite, manganese, and possibly carbonates showing on the dump. Using the dump rock, judiciously, might not adversely affect the watershed, but please do not fill any drainage areas with it.) 4. You have stated that as new rock is placed, the dump will be shaped. Please verify ifthis means shaped to a 3:1 slopes, and how often or a[ what point in your operating season it is to be shaped. Also please indicate how you will mark or maintain the 17-foot setback from Red Cloud Creek (as shown on the new maps).
