Jim McArdle October 30, 1980 Page 3 13. Climax expects to construct a new drainage system in and around the completed tailings area. Will this drainage system be capable of supporting a fishery? What is the anticipated final design of this system? What will prevent the new channel'(s) from cutting into the tailings? 14. Can wet meadows be created somewhere to replace those lost? 15. Will a water table develop in the abandoned tailings? At what depth - where? 16. Does Climax guarantee that certain water quality standards will be met upon completion of mining? Will they be class one standards? We see no real commitment on this and feel it to be important. It is our opinion that class one water quality standards must be guaranteed for the protection of Dillon Reservoir and to main- tain a respectable trout fishery in Ten Mile. 17. Of the total amount of water entering Ten Mile Creek (post mining), what percent is surface water and what percent ground water? Again. what are the ground water and surface water patterns in the Ten Mile and Arkansas basins expected to be - post mining? 18. On page 8-13, it is stated that post mining surface runoff water from tailings, etc. is expected to be of comparable quality to runoff from natural alpine terrain. What is the basis for this remark? It may be conjecture. 19. How many miles of stream and acres of riparian habitat have been lost to date? 20. What final reclamation is anticipated for the spill prevention dam? Will it become just another tailings pond? or, will it be designed for reservoir storage? 21. Ponds, reservoirs, etc. (i. e. , Glory Hole) are proposed or implied to be part of final reclamation. Yet, we find no commitment on the management and maintenance of these lakes. Will they be used for mitigation of wildlife resources and habitat lost? Will conservation pools be maintained? Will water within these lakes be used to maintain minimum stream flows?
