The two upland <br />areas U1 and U2, are separated by an area conducive to a pathway that <br />could provide a migratory corridor (identified on the attached map, <br />identified as Figure 1) for the skipper butterfly to move past the mining <br />operation. No mining or disturbance except for a 25 foot wide access road, <br />the location of which to be reviewed and approved by the SUB Director, <br />will take place within this corridor. <br />3) With Area 1L removed, a majority of the mining will occur on land that is <br />either in the adjudicated reservoir site or in the most impacted piedmont <br />grassland that is currently characterized as primarily short-grass prairie <br />with only limited occurrences of typical piedmont grassland species. <br />Schmidt agrees to commence mining in the adjudicated reservoir site as <br />soon as practicable. <br />4) It is agreed that limiting excavations to those areas where sand is present <br />as shown in Figure 1, plus some land surrounding those areas fur <br />stockpiling topsoil and overburden (stockpiling is included in the 300 acre <br />limit) , the mining would be reduced to a point where the impact on <br />piedmont grassland and otter associated habitats would be acceptable to <br />SLB. <br />Figure 1 shows the allowable boundaries of the areas to be mined, the area to be <br />removed from the mining plan, and the various corridors that would remain. Some of <br />Area 1 L remains, but only that area within the estimated footprint of the reservoir dam. <br />The boundaries of the mining areas to remain in the plan are close, but not exact as the <br />full extent of the sand deposit and the amount of land needed to stockpile topsoil and <br />overburden are still difficult to precisely identify. However, the exploratory pits show a <br />pattern where mineable sand is present (yellow and green circles) and where sand is <br />either not present or of such low qualify it would not be worth mining (magenta circles). <br />The zones where mining would occur leave a suitable setback from the most significant <br />drainage course (about 200 feet wide at the narrowest) to protect most of the resources in <br />these areas. <br />A roadway will connect area 1 U and 2U crossing the drainage at the crossing <br />location. This road would be similar in size to the existing east west road that currently <br />passes through this area. It should be noted that there may be some minor disturbances <br />outside of the raining areas such as post storage for the fence building as a staging area, <br />but these would not destroy vegetation or remove soils. <br />The map also shows an acreage accounting for this area. In summary, the 635 <br />acres in all identified mining areas would be reduced to around 580 acres by the removal <br />most of Area M. The probable mining areas total 300 acres which leaves about 280 acres <br />ofthe 580 acres with little or no disturbance occurring. <br />It should be noted that this is a significant reduction from the originally
