• <br /> <br /> <br />width. The road to the fan is used once a day to check the fan and the road to the <br />portals is used a couple of times a month for inspections of the site and the substation. <br />Drainage -Due to the limited use of the roads the drainage control primarily consists of <br />graveling natural drainages across the road. The location of these cross drains is <br />shown on Exhibit 57. <br />Surfacing -The road surface for most of this access road is dirt or existing rock <br />surfaces. <br />Maintenance -The road is graded occasionally to eliminate ruts and to promote <br />drainage. Additional water bars or gravel will be installed as necessary to minimize <br />erosion. <br />Structure <br />Location <br />Construction Dates <br />Access Road 4 CRDA 1, Exhibit 9B <br />(Formerly Access Road #g) <br />2002 <br />Description -This road is projected as access to Cameo Refuse Disposal Area <br />(CRDA) No. 1 for hauling final cover material. The 1,200' of road will extend from Haul <br />Road 4 near Coal Gulch, cross Coal Gulch and then up a hill to the south where it will <br />cross onto CRDA 1. <br />Design and Construction -The road will be constructed on a weathered sandstone <br />and shale hillside. Cut and fill methods will be used to construct a 20' roadway <br />including a MSHA berm along the outside edge of the road. The maximum cut slope <br />will be 1.5h:1v in unconsolidated material and 0.25h:1v in bed rock. The average <br />grade will be 10%. <br />Drainage -Drainage control for this road will involve grading the road to the inside to <br />collect runoff and direct it to Pond 11, see Appendix 13-1 for design. A 24" CMP <br />culvert will be installed where the road crosses CRDA 1's NW collection ditch, see <br />Appendix 13-2 for design. <br />Surfacing -Due to the high natural rock content of the road cut and the temporary <br />nature of the road, no roadbase will be used and a minimal amount of 3/4 roadbase <br />gravel will be used. <br />Maintenance -The road will be watered regularly during use and grading will be done <br />on the road to eliminate ruts and to promote drainage. <br />T13-2-8 <br />(Rev. 02/28/2002) <br />
