The perimeter of all azeas affected by surface disturbance will be clearly marked before initiating surface <br />disturbance activities. The proposed utility borehole pad area is approximately 0.92 acres in size with <br />minimal cut and fills. Temporazy drainage and sediment control measures (silt fence and/or straw wattles) <br />will be established prior to proceeding with surface disturbance activities. <br />Given an average topsoil depth of approximately 6 inches and a total pad disturbance area of <br />approximately 0.92 acres, approximately 740 cubic yards of topsoil will be salvaged from the pad azea. <br />Prior to initiating topsoil removal activities, stream and wetland buffer zones will be marked with <br />identifying signs to limit surface disturbance within these areas to the planned and approved activities. <br />Topsoil from the pad area will be placed in a stockpile or windrow on the upslope perimeter of the pad. <br />Topsoil salvage volumes are indicated on Table 49A. Natural vegetative materials (mulch) incorporated <br />into the topsoil, and seeding with the topsoil stockpile stabilization seed mixture identified on page 2.05- <br />121 will stabilize the stockpiled topsoil. Active use areas will be graveled to control dust and drainage, <br />other disturbed areas (including topsoil stockpiles) will be stabilized with temporary vegetation. <br />MROS-198 2.05-45.66 08/29/05 <br />
