They are <br />summazized as follows: <br />MR 126 <br />Minor Revision 126 BME proposes to recontour the intersection of County Road 65 and <+ <br />the haul road to improve traffic visibility and public safety. In the process of this .-, • . <br />recontouring we will use excess fill generated to replace soi] borrowed from the pad area <br />of RS-2 (approximately 440 CY) and to stockpile for the eventual sealing of RS-3 <br />(approximately 360 CY). <br />The attached orthophoto shows the areas where we propose to remove material and place <br />additional excess fill. Both areas proposed to receive excess fill are on existing <br />disturbances. The northern fill area is an area that would require fill placement upon final <br />closure. Thus, this fill would remain in place through final closure. We estimate that the <br />southern fill azea will receive 1550 cubic yards of material. This fill area will be fairly <br />shallow to avoid obscuring the visibility for traffic. Maps 58 and 71 were modified to <br />document the change in disturbance and fill storage (Blister 6). Changes pertinent to this <br />minor revision were also made to Map 147 but are included in the MR 127 submittal. <br />Areas disturbed will be ripped on contour and seeded to minimize erosion and <br />sedimentation potentials. The southeast cut area will slope approximately 6.25%; the <br />northwest cut area approximately 2.6%. Hydrologic modeling for the relatively flat drill <br />sites (Illustration 44) demonstrate negligible sediment generated from such sites. Water <br />quality and sedimentation modeling for Blister 6 is addressed by "Typical Topsoil Piles" <br />demonstration found in Illustration 44. <br />While topsoil thickness is very limited throughout these areas topsoil salvaged will be <br />placed in haul road topsoil stockpile R3. <br />... <br />3607 County RD q65 <br />Rangely, CO 81648 <br />970-6754300 <br />Fax 970-6754399 <br />
