Battle Mountain Gold Company - San Luis MLRD Permit No. M-88-112 Technical Revision No. 11 Responses to Division's Adequacy Comments (1) Is the proposed storage area intended to accommodate both empty and full cyanide flo-bin hoppers? Both empty and full cyanide bins will be stored in the new structure. (2) What precautions will be taken to ensure containment of cyanide during the unloading and loading of the flo-bins for transport to and from the site? As noted during the Division's recent inspection, the transport trucks cannot drive into the storage area. The trucks will be parked as close to the area as possible during loading and unloading. The bins arrive on-site in a locked, sealed gate position. Prior to unloading, all bins will be visually checked to ensure that the locked position is intact and that the bins are structurally sound. The forklift operator will then transfer the bins into the storage area. The empty bins will be visually checked prior to loading to ensure that they are in a locked position and that the bins are structurally sound. The empty bins will then be loaded onto the transport trucks. During loading and unloading other traffic in the vicinity will be minimized to the extent possible to lessen the potential for collisions. Forklift operators will be trained in the proper emergency responses and reporting, as outlined in the approved Emergency Response Plan, in the unlikely event that a spill occurs during loading and unloading of the bins. (3) Is the cyanide feed system equipment within the new storage area? If not, what precautions exist to ensure containment during the transport of the full flo-bins From storage to the injection apparatus, and the return of the empty flo-bins to storage? The cyanide mix tank is located at the north end of the mill facility, while the storage area is located at the southwest end, several hundred feet away. The bins are transferred from the storage area to the mix tank using forklifts in a similar manner to the unloading/loading procedures described earlier. The containers will be visually examined prior to transport to and from the mix tank. In addition, the outside of empty tanks will be thoroughly washed before moving from the mix area to the storage area.
