January 2, 1969 ~a~ c lgee Mined Land Reclamation board Dept. of tvatural Resources, State of Colorado 215 Centennial B1dE., 1313 Sherman St Lenver, CD 80203-2273 Dear Sirs: R~CE~~E'D I.AIFIED ~,ND t5~0-~ (DECLAMATION b Pleeae accept this letter as a listing of my concerns regarding the Battle Mountain Gold Company mining plan. The reference in brackets at the end of each paragraph refers tc the mining plan section. 1. She stability of the East Pit xall due to its closeness to the Rito Seco Creek is unYnoxn. A potertiel serious hazard to people may exist as the heavily used road to Forbes property and P.ito Seco Fart. passes through this area. Amore thorough study must be conducted. [D 2.5] 2. Regarding possible eerthauake damage, the mining plan does not state that facilities are placed "on the foot xall block of the San Luis fault segment" as a study in the Appendix recommends. In the u.•zlikely even of an eerthauake, damage to the heap leach and/er mill facility xould present an extreme danger to the cosnunity dox~nstream. Probabilities do not suffice as protection schemes for the community. The Centennial School xhere I teach, is located about tv^ee miles docrnstream from the nrooosed tczic areas. [Sec. D] _ 3• The stability of Haste Rock Disposal E_ ens is not 1II compliance ~,-ith D.S. ~~}- Carps of ~:gineers rinimums. BMG should at least adopt these +-~^~r~s. [D-2'I] 4• The heap leach fac~'itq design utilizes the 1D0 veer, 24 hour storm event model. Considering the extreme hazard posed to residents in San Luis, the facilay design must use the most extreme storm concitioas es its parameters. As e life-long resident of San Luis, I have seen same terrifying flood conditions as lived in town next to the Rao Seco. The toxic areas, most u_-L{ortu.-ietely, ere tlanned to be in the P,ito Seco flood slain. Thousanes of tons of Sodium Cyanide sill be introduced into the area. The xell-being of the common=ty must be a very ii~Ch priority. [D-32]
