Each site will be discussed individually. A work sheet was created to ensure that the same <br />questions and concerns were reviewed for each site. <br />JD-6 Mine, M-1977-310 <br />The JD-6 MINE is an underground mining operation that uses two adits from the Mineral Joe <br />Claims for access and emergency egress. <br />1) Waste materials from the JD-6 are currently being used to gob or backfill old workings <br />underground. There are no current plans to bring waste materials to the surface, but that <br />could change in the future. No geochemical analysis of the waste has been conducted at <br />this time. <br />2) The JD-6 is a dry mine with little water interception by current underground workings. No <br />CDPHE is required at this time. There is no dewatering or discharges from this mine. <br />3) Current surface disturbances are actually part of the Mineral Joe Claims and will be <br />discussed in that section. <br />4) The Division has maps for the permit area dated from .1-.977. Although not much has <br />changed updated maps and remarking of boundaries where-necessary will be required. <br />5) Reclamation standi3rds for waste piles and adits are cdvered under the Mineral Joe' <br />Claims. ~ - <br />Overall, most of the surface impact from the JD-6 is covered under the Mineral Joe Claims. The <br />Department of Energy originally required the operator to segregate waste from the JD-6 and <br />Mineral Joe Claims. Since that original request, DOE has relaxed that stipulation and no longer <br />requires segregation. <br />Mineral Joe Claims, M-1977-284 - -~ <br />The Mineral Joe Claims are associated with the mining activities at the JD-6. Mine structures <br />and surface disturbances at the Mineral Joe are directly connected to mining at the JD-6 Mine. <br />1) Current historical waste rock piles at the surface of the Mineral Joe Claims are currently <br />deposited along the eastern edge of permit boundaries. Waste rock piles are in a natural <br />angle of repose along the west side of a small drainage. Some major erosion has <br />occurred which was noted in a previous inspection in 2002. The area was impacted by a <br />major precipitation event, which caused problems for several mine sites and local <br />drainages. The operator has taken measures to redirect stormwater away from these <br />impacted areas and around the waste piles. Reclamation plans call for the waste rock <br />piles to be pulled back to a 2:1 slope in its final configuration. No visible signs of other <br />impacts to the drainage were observed. <br />2) A geochemical analysis has not been done on the waste generated from the JD-6 or <br />historic Mineral Joe. Staff has agreed with Cotter that a composite waste rock sample <br />from the JD-6, JD-8 and JD-9 will be sufficient to analyze constituents within the rock to <br />determine if there is anything detrimental to the environment. The reasoning for the <br />composite sample over individual samples is that all the mines are going through the <br />same geological formations within a relatively close geographical relationship. Therefore, <br />it appears to be a safe assumption that since the rock is rather homogenous in nature a <br />composite sample will be representative of the entire strata. <br />
