of these routes, they will be Snstalled per Attachment 13-9, LSght-Use Roads Generic __ <br />Culvert Design. Field work on both of these routes must begin one to two weeks prior • <br />to the dragline deadhead. Reclama tlon activities for both these routes will begin <br />immediately following the passage of the dragline and approximate the conditions prior to <br />the disturbance. Seneca anticipates that both of these deadhead routes will be reclaimed <br />within three to four weeks of Snltial disturbance, unless probl ears would occur during the <br />walking of the dragline. These roads will be revegetat ed with the seed mixes contained Sn <br />Tab 22. <br />The first construction activity will be the temporary deadhead/detour road to route <br />traffic along RCR 27 while the dragline crosses the road. This work will consist of two <br />separate roadways. The detour road for RCR 27 will begin approximately 300 feet from the <br />Sntersection of RCR 27 with the Yoast Road "A". The detour road will be 60 feet wide for <br />approximately B00 feet and then narrow to a 30-foot wide roadway. This road will tie back <br />into RCR 27, roughly 900 feet to the south of the intersection of RCR 27 and RCR 27A. The <br />detour road depicted on Exhibit 13-13 shows the `ti+o rst case" disturbance. If at all <br />possible, Seneca will try to shift this road Eu rther to the north and avoid having to <br />Snstall a temporary culvert and disturb the existing stockpond dam that is located Sn this <br /> <br />area <br />The second roadw <br />will be a 100-f <br />t wid <br />ction that h <br />s a l <br />th of 300 feet • <br />. <br />e se <br />a <br />. <br />ay <br />oo <br />eng <br />This roadway will be located at the Sntersection of RCR 27 and 27A and will tie into the <br />detour road where it narrows from 60 to 30 feet. This road section will be used to <br />stockpile the straw and dirt which will be used to cover RCR 27 to protect St while the <br />dragline crosses it. Once the dragline teaches Haul Road "A", it will continue towards <br />the mining area on St. Reclamation of these roads will then commence. <br />The second construction will be the deadhead route to cross under the PSCO/WAPA <br />powerllnes. This 4500-foot long section of road will start at Station 42+00 of Yoast Road <br />"A". The ex lsting ground profile for this deadhead route Ss shown on Exhlblt 13-19. It <br />will take off to the northwest for 1100 feet to the drainage just north of the "A" haul <br />road. The next 1100 feet of road will be constructed in this drainage Sn a southwesterly <br />direction. The reason for building the toad Sn the drainage Ss to maintain the minimum <br />distance required for walking the dragline under energized powerlines. The approximate <br />height of the dragline while walking will be 62 feet. According to 30 CFR 77,807.2, a <br />chart provides the minimum distances which must be maintained while operating equipment <br />within different ranges of voltages. To minimize the amount of disturbance assoclatetl <br />with this move and to obtain the necessary clearances, Seneca had to construct the __ <br />13-10-2 Revised 09/23/96 <br />
