material derived from a nearby source material that was originally to the south, extensive clay layering <br />would no[ be expected. It is likely that alluvial deposits extend [o a considerable depth before <br />encountering bed rock. The depth to bedrock which is probably an early Cenozoic sandstone is not <br />known. <br />Pre-Mining Issues of Importance <br />Permit Area, Affected Land Area, and Phasing <br />PERMIT AREA: The permit area is well defined by straight lines that are extensions of existing lines <br />marked by fences. The eastern boundary and part of the southern boundary are currently not marked by <br />fences. The eastem boundary begins 800 feet east of the current east fence of the current permit. This <br />boundary extends southward until it intersects a line extended eastward from the east-west fence that <br />currently defines the south boundary of the current permit. The remainder of the north, west, and south <br />boundaries are unchanged from the current permit. Those are all identified by existing fences. <br />AFFECTED LAND AREA: The affected land area is identical to [he permit area. It is expected that <br />disturbance within the amendment area will extend to the edge of the permit. However, if, in specific <br />locations, no mineable material is encountered then portions of the affected land may no[ be extensively <br />disturbed. Due to some question regarding the overall continuity of the deposit and indications that some <br />areas are devoid of mineable sand, some areas may experience little or no disturbance. <br />PHASING: This operation, being small and compact, has not been divided into phases. <br />General Groundwater Considerations <br />Groundwater is present deeper in [he deposit. Mining of [he sand is no[ expected [o encounter the <br />water table. As described below, if groundwater is encountered, mining must no[ extend deeper and [he <br />exposed groundwater is to be promptly covered so it is no longer exposed [o evaporative loss. <br />Wash water for processing of [he sand is obtained from the small wash pond which is connected <br />to the alluvial water of Running Creek. In [he future, as has been the case in [he past, this source and its <br />use is covered under a Substitute Water Supply Plan approved by the Slate Engineer and the Division of <br />Miller Gravel Pit Amendment (2007) Exhibit D Page 2 of 5 <br />
