<br />t <br />-2- <br />3. Please describe more specifically how rock extraction will occur. If <br />rock is blasted, provide evidence that blasting plans will not adversely <br />affect any off-site structures. Also, you should contact the Colorado <br />Division of Mines and/or local Mine Safety Health Administration (MSHA) <br />office regarding blasting plans and quarry wall safety regulations. <br />4. If water is encountered during the course of the operation, a technical <br />revision will need to be submitted for the installation of a sediment <br />pond. <br />5. What will be the slope of the highwall during mining? Please discuss <br />the stability of the highwall. <br />Please provide the volume of topsoil on the site. <br />Exhibit F - Reclamation Plan <br />1. A seed mix and seedbed preparation plan were not submitted with the <br />permit application. Please submit the above items. <br />2. The mine site has been identified as a critical deer and elk habitat by <br />~he Division of Wildlife. The reclamation plan needs to reflect the <br />needs of the species impacted. Please discuss in detail the following <br />suggested changes to your reclamation plan. <br />a. Planting mountain mahogany and bitterbrush as part of your <br />revegetati on plan. r1d /7QQq~ ~ nG,nt <br />b. The proposed 40' highwall poses a /safety hazard to wildlife and <br />people. The highwall should be benched so that the maximum height <br /> <br />of the highwall would be between 10-15 feet. <br />c. Irregular benching and the use of keyways to enable wildlife to <br />access the site upon reclamation. <br />d. The bench areas should be backfilled with topsoil or an appropriate <br />growth medium and reseeded. <br />~~1n e. Mining activities will only occur between June and September of each <br />t' year. <br />4. Reclamation of the highwall should be concurrent with mining. The <br />highwall should be benched and contoured to its final configuration <br />during the mining process and revegetated. <br />Please provide a map which would show the final configuration of the <br />highwall, including benches and slopes. <br />Please discuss the stability of the reclaimed highwall. <br />
