1 <br /> • 2.05. 3 (3 ) (c) <br /> ACCESS TO STATION TO STATION DRAWING NO. <br /> 1 ) Ponds A & B 75+00 to 99+00 123 <br /> 2 ) Topsoil Pile #1 100+00 to 103+00 124 <br /> 3 ) Pond C 104+00 to 119+00 123 <br /> 4 ) Pond E 120+00 to 125+00 123 <br /> 5 ) Pond D 126+00 to 140+00 124 <br /> 6) Topsoil Pile #2 141+00 to 145+00 124 <br /> 7 ) Office Area 146+00 to 149+00 124 <br /> Topsoil will be stripped from the haul road align- <br /> ment prior to the start of construction of the road. Borrow <br /> ditches typically 18' deep will be excavated on one or each side of <br /> the road to provide material for the subgrade of the road. Where <br /> necessary, depending on the subgrade condition and the intended use <br /> of the road, gravel surfacing will be placed on the road. The road <br /> surface will be 20 feet wide. Road #1 has a pitch grade of 15% for <br /> 600 feet and road #4 has a pitch grade of 12% for 150 feet. All <br /> other access road grades are less than 10% so the overall grade of <br /> the access roads is obviously not steeper than 10%. Cut and fill <br /> slopes will be constructed using 1. 5H: 1V slopes . <br /> Drainage for the access roads will be provided by <br /> borrow ditches and numerous culverts . The sizing calculations for <br /> • the ditches and culverts are presented in Exhibit 9 . One of two <br /> ditch and culvert sizes will be used for all of the access roads. <br /> Either an 18 inch culvert with an 18 inch deep borrow ditch or a 24 <br /> inch culvert with a 24 inch deep borrow ditch will be used. The <br /> culverts to be used are numbered 1 through 12 and are shown on the <br /> drawings and the sizing calculations are presented in Exhibit 9. <br /> Where borrow ditch drainage runs through a 18 inch culvert, an 18 <br /> inch borrow ditch will be constructed. Where borrow ditch drainage <br /> runs to a 24 inch culvert, a 24 inch borrow ditch will be <br /> constructed. <br /> To provide erosion control, the borrow ditches and <br /> cut and fill slopes will be seeded. The seed mix used will be that <br /> used to stabilize the topsoil stockpiles or other appropriate seed <br /> mix approved by the Division. Broadcast seeding will be used. <br /> Six of the seven access roads have been reclaimed or <br /> were never constructed. The No. 1 Access Road that provides access <br /> to Ponds A & B has not been reclaimed. The No. 1 Access road may <br /> remain in place to provide access to the ponds . By a letter dated <br /> August 1, 1991, the landowner requested that the two sediment ponds <br /> be left in place. They view the sediment ponds as an asset. The <br /> issue of leaving the ponds in place and not reclaiming the No. 1 <br /> access road will be addressed by a future permit action. The <br /> access road and ponds will be required on site until vegetation is <br /> • established and it is demonstrated that the requirements of Rule <br /> 4 .05.2 (2 ) are met. <br /> 2 . 05-7i January 1994 <br />
