<br />~, <br />~~ <br /> EXHIBIT ~ <br />PIINING PLAN <br /> ~ <br /> Mining of <br />material borrow area C will provide a pervious bedding <br />for construction of the Windy Gap pipeline from <br /> the diversion dam area to Lake Granby, and material for <br /> continued maintenance operations over a period of years. <br /> Mining operations will begin at the southerly end of the <br /> bench and continue northward. It is estimated that a maximum <br /> of 36,000 cubic yards of bedding material would be removed <br /> from this site. The site obviously has a capacity well in <br /> excess of 36,000 cubic yards. <br />MINING METHODS <br />Because the material is not compacted, no blasting is <br />anticipated to remove the aggregate material. Bulldozers, <br />scrapers, front loaders, and haul trucks will be the primary <br />instruments of mining. The topsoil will be removed from the <br />bench and stored as indicated on Figure C-2. It is estimated <br />that approximately 4 feet of overburden will have to be <br />removed from the top of the bench in those areas affected by <br />mining. The overburden material will be stored and seeded. <br />WATER RESOURCES <br />Development of this borrow area should not impact water <br />resources. No dewatering operations are anticipated because <br />of the relative elevation of the mining area to surrounding <br />water courses. Some application of water may be required for <br />control of fugitive dust. It is anticipated that the <br />contractor will purchase this water from a local source with <br />an established water right. Drainage will be effected in <br />such a manner so as not to cause sediment loading in Willow <br />Creek. It is anticipated that drainage will be towards Willow <br />1 Creek; however, a large, wide intervening meadow will filter <br />any runoff prior to its intercepting Willow Creek. <br />TIMETABLE <br /> The timetable for mining and reclamation activities is shown <br /> on Table D-1. The table is based on the assumption that the <br /> contract will be awarded in June, 1981, a nd that construction <br /> will begin in July, 1981. It is possible that the contract <br /> could be awarded as late <br />a delay of project initia as August, 1981, <br />tion if that occ and there could be <br />urs. Topsoil removal <br /> in the pervious borrow ar ea would begin i n July, 1981, and <br /> actual mining of the area may occur then. Active use of the <br /> <br />' D-1 <br />
