MMRR Quarry, M-2004-067 <br />Response to June 30 Adequacy Review (as amended) <br />August 19, 2005 <br />Page 11 <br />31. Fuel/Oil Storage. The applicant has specified that fuel and oil needed for equipment will be <br />stored on site and that primary containment will be an engineered impoundment enclosing the <br />tank site, with a volumetric capacity of at least 150% the capacity of the tank or combined tanks. <br />Please provide either designs and plans depicting the dimensions and materials of the <br />engineered impoundment or a commitment to provide such information via a technical revision at <br />some future date, and prior to any site disturbance, so the Division can calculate an itemized cost <br />for removal of these structures. <br />The applicant commits to providing detailed plans for fuel and oil containment, as <br />appropriate for the purposes of bonding, prior to any disturbance on the site. <br />Please note that, as previously stated, the operator will comply with all applicable <br />regulations pertaining to Spill Prevention, Control, and Countermeasures (SPCC) <br />plans. In terms of SPCC regulations, the Division of Minerals and Geology has <br />an adopted policy stating that, "It is not necessary to provide the Division a copy <br />of the SPCC plan, but it must be available for review at the facility or the nearest <br />field office during an inspection conducted during normal business hours. The <br />operator must submit a letter to the Division, on company letterhead, affirmatively <br />stating that the plan has been implemented." Operations at the MMRR Quarry <br />site will comply with DMG policy. <br />Please also see the attached letter from Project Attorney Chris Hayes for further <br />discussion of this item. <br />Exhibit E -Reclamation Plan <br />32. The applicant has specified the post-mining land use is wildlife habitat. Based on the <br />information provided to date, it appears the 500+ acre permit area has limited value for wildlife <br />habitat. Please indicate what specific measures the applicant will implement to enhance the <br />potential of the affected land for wildlife habitat and what species will be benefited by such <br />measures. <br />The proposed post-mining land use of wildlife habitat is consistent with plans for <br />the surrounding area of Gilpin County, as well as existing and likely future land <br />use in the vicinity (see Rule 6.4.5(2)(b)). <br />The existing conditions on the site are of limited wildlife value and will be <br />enhanced through the reclamation process. While the current landscape does <br />function in general as wildlife habitat, a number of existing conditions tend to <br />severely limit the types and quantity of wildlife that are supported on the site for <br />any duration of time. Lack of open water and poorly developed soils are the <br />fundamental limitation on current habitat capacities. As a result, grasses, trees, <br />and shrubs suitable as a food source for wildlife are relatively sparse. The <br />footprint of the proposed quarry area itself is highly exposed, and south and west <br />facing slopes throughout this footprint are generally poorly vegetated. <br />The goal of the reclamation plan is to enhance biological productivity in the post- <br />mining wildlife habitat. This condition will exceed the current wildlife value of the <br />
