North River Gravel Pit Weldon Construction <br /> 5.3.1. Topsoil and Overburden Handling <br /> Topsoil and overburden on the site ranges from 1 inch to 3 feet thick. The upper 2-12 inches of <br /> previously undisturbed areas is likely useable soils/growth medium, and therefore would be <br /> salvaged for use in reclamation. No overburden (or very little overburden) is expected. Topsoil will <br /> be stored in and around the existing storage areas shown on Figure 5: Exhibit D - Mine Plan Map. <br /> These areas may contain a total volume of approximately 25,000 CY of topsoil. Any overburden or <br /> non-marketable subsoil would be kept separated from topsoil. Any overburden would be used as <br /> backfill for reclamation. <br /> 5.3.2. Water Handling <br /> As the pits are well over 100-feet above the White River, no dewatering of pits is anticipated. Given <br /> the xeric site conditions, no perimeter dewater ditches are anticipated; any pooled waters within the <br /> pits would be allowed to evaporate. <br /> Existing surface drainage will be maintained throughout mining operations. All mining and <br /> processing operations will be designed to manage storm runoff and prevent sediments flowing into <br /> existing drainages and the White River. <br /> 5.3.3. Schedule of Operations <br /> The North River Gravel Pit will operate from 7 am to 8 pm Monday through Saturday, as needed. <br /> No nighttime activities are anticipated. Occasional equipment repair, or maintenance may be <br /> conducted at night, but lighting will be kept to a minimum and directed inward; the site will not have <br /> ambient lighting. <br /> 12 <br />
