S) Mining Operations. Reference Exhibit C (e.g., sheet'/, MINING. EXCAVATION AND LAND LEVELING OPERATIONS, Section 4, paragraph 6), revise to specify portable processing operations. This is already explicitly stated in Exhibit D, page 1, in which the processing mechanism is described as a portable plan[. 6) Onsite Storage. Reference Exhibit C (e.g., sheet'/+, MINING, EXCAVATION AND LAND LEVELING OPERATIONS. Section 4, paragraph 7), stipulate that no storage of any fuels or otherlm,ardous materials onsite is planned per Mr. Phillips (Rule 3.1.7.(6)(b)(ii)(B)). Again, it is assuma:d in the absence of any statement to [he contrary that no such materials will be stored onsite; however, the Division is requesting that this be clarified. 7) Improved Mitigation. Require that complete climate information be provided, specifically as it relates to seasonal wind direction and velocity (Rule 6.4.1 I). Many of the following suggestions arose out of a June 26, 2000 meeting among interested parties and various representatives of interested county and state agencies. Require anemometer to monitor wind force & speed, noearth-moving operations when wind exceeds 30 mph. (Reference Lynn Robbio Wagner/Tri-County Health). There are no DM(i Regulations which specifically require these measures. Their inclusion in the Reclamation Plan is left to the discretion of the Applicant. Establish a living snow/wind fence. Awell-established fence will mitigate the impact of visual blight, noise and highly erosive winter winds; aid in containment of fugitive particulate; stabilize the buffer zone to mitigate water erosion of mined/reclaimed areas; and provide a natural screen to mitigate mine impact on area wildlife (Reference Lynn Robbio Wagner, Robert Zebroski, and Daniel Parker.) There are no DMC; Regulations which specifically requires these measures, as well. Their inclusion in the Reclamation Plan is again, left to the discretion of the Applicant. 8) Concurrent Reclamation. Although implied in the application and discussed in the Arapahoe County meeting of 6-26-00, nt:ed language in Exhibits C (e.g., Sheet r/a, MINING, EXCAVATION AND LAND LEVELING OPERATIONS, Section 4, paragraph 9), D and E that concurrent reclamation will be employed and that mute site will be regraded to historic contours. Limit the maximum acreage requiring reclamation at any one time to 24 acres. This would ensure concurrent reclamation and minimize topsoil loss due to erosion, soil-moisture loss due to exposure, topsoil degradation due to stockpiling, and the costs of stabilization (.Rule 3.1.5(1), (2), (3) and (5), 3.1.6(3), 3.19(1) and (3), and 6.4.4(2)(e}). The question regarding final contouring of the site is addressed in the Division's comments above, in Concern #3. The maximum acreage to be disturbed at any one time is left to the discretion of [he Applicant as long as sufficient Financial Warranty for the amount disturbed is posted with the Division, in accon~ance with Rules 4.1(4) and 6.4.3(d) of the Construction Materials Rules and Regulations. [mplement immediate soil stabilization for topsoil to be stockpiled more than one growing season; e.g., plant with perennial gt~ass cover (Rule 3.1.9(3)). The question of topsoil storage and stabilization at the site is addressed in the Division's comments above, in Concem #I.
