(b) The approximate volume of inert material to be placed. <br />(c) A signed affidavit certifying that the material is clean and inert as defined in <br />Rule 1.1.(20) <br />See Attached. <br />(d) The approximate dates the proposed activity will commence and end <br />The proposed fill activity will start as soon as approval is received from DRMS. All fill <br />activity is expected to be completed by April 30, 2010. <br />(e) Explanation of how the backfilled site will result in a post- mining configuration that is <br />compatible with the approved post- mining land use <br />The approved post- mining land use is a water storage reservoir. The reservoir site is <br />at the base of a hill and as a result it collects runoff. Since urban runoff carries <br />sediment and other pollutants that affect water quality, such runoff should be <br />rerouted around the reservoir to the extent practical. To do this, fill is needed to <br />raise the existing low areas to drain correctly. Since the pit area has already been <br />converted to water storage, no further fill materials can be excavated and imported <br />fill must be used. Fill is also needed to backfill and stabilize areas prone to erosion <br />and to flatten the ditch banks to allow for mowing.
