5. The text in several locations in this application indicates that no hazardous materials are to be <br />stored on site. However, this does not appear consistent with plans to operate an asphalt batch <br />plant. Please provide specifications for spill containment for all containers of hazardous materials <br />that may be stored on site. <br />6. A layer of loose material must be left on the pit floor and covered with topsoil to provide a rooting <br />zone for revegetation plants. Please specify if a minimum two foot layer of gravel will be left in <br />place over the underlying shale layer, if the shale layer will be ripped to a minimum two foot depth <br />prior to topsoil placement, or if a minimum two foot layer of overburden will be used to cover the <br />shale prior to topsoil placement. <br />7. Please verify than no explosives will be used in conjunction with the mining and reclamation <br />operations. <br />Exhibit E -Reclamation Plan <br />8. DMG does not recommend that the entire acreage be disturbed and mining completed before <br />reclamation (except slope grading) begins on the site. Weed infestation and erosion may become a <br />significant problem on affected areas left idle for long periods of time. Much of the current pit site <br />has been mined and left unreclaimed to date and has yet to be utilized for any storage. DMG <br />recommends that total unreclaimed acreage be maintained at no more than 20 acres. This would <br />allow for the site to be reclaimed in two phases. <br />9. Please specify a minimum topsoil replacement depth for affected areas. A minimum of six inches is <br />recommended. Additional thickness may help improve revegetation success and shorten the <br />timeframe to achieve this success. <br />Exhibit G -Water Information <br />10. If applicable, please submit the statement specified in Rule 6.4.7. The current statement is not the <br />equivalent. If this statement is not applicable, please submit all information required by Rule <br />6.4.7(2) <br />11. If water consumption is expected for operation of the asphalt batch plant, please include these <br />volumes and sources as required by Rule 6.4.7(3) and (4). <br />12. Please remove the statement that "tJo acid, toxic, nor waste products shall be involved in the <br />proposed action". This statement is not consistent with the proposal to operate an asphalt batch <br />plant. <br />Exhibit I -Soils Information <br />13. Please provide the soil descriptions for soil types Ru, Rr, and ShC and revise the mine plan map to <br />delineate all applicable soil types consistent with the Exhibit I Map. <br />14. Please ensure that soi4 descriptions for al{ soil types include thickness and suitability for plant <br />growth. <br />Exhibit J - Veoetation Description <br />15. Please provide an estimated figure for percent vegetative cover and average height for each <br />vegetation life-form type. Also include an estimated carrying capacity. <br />
