ENVIRONMENTS INC. PAGE 2 DECEMBER 9, 2DO4 Rule 6.4.5 Exhlblt E -Reclamation Plan 5. As we discussed at the inspection, a fence will be located up hill from the working face to isolate the mining area. It will extend east to west across the site and be tied into the perimeter fences so no livestock can enter the mine. Ini- tially it will not enclose the entire permit area so the landowners can continue to use the unmined area for grazing. The fence will be moved as mining progresses until eventually it encloses the entire site. 6. The ditch is intended to keep the minor storm event water from entering the mine. The basin that would collect storm water on the site covers 44.0 acres t and is entirely on the mined area. In the case of a 100 year event the runoff would have to be retained on site and treated before it could be dis- charged. we estimate that this would amount to an accumula- tion of 1.76 of-ft of water that could potentially enter the mined area from the upgradient drainage basin. The pond shown on the map addressed in item 7 will be built to retain the amount noted above. Its approximate size will be 0.58 acres and 4.0 feet deep with 3:1 side slopes 7. The revised Mining Plan Map shows the approximate location of the stormwater retention pond. Rule 6.5 Geotechnica/ Stability Exhibit 8. I received this on 11/19/04 and will address Mr. Sorenson's review in the order presented. The three conditions proposed are acceptable. We understand the reasoning behind each and agree to limit charge weight to 1000# per 8 millisecond delay, having the stemming height a minimum of 15 times the hole diameter and will keep records for each shot on the supplied form. To clarify the mining plan, the benches will only be developed on the 40'x 40' configuration as stated. This will apply to the perimeter of the mine and working face during mine development. I any changes are made to this plan .will not be made until the necessary permit revision will be submitted to the Division of Minerals and Geology for review and approval. We concur with Mr. Sorensons suggestion to do additional rock analysis in the future. We are not sure how much time it will take to expose enough rock face to do a proper analysis so propose placing the analysis schedule on a physical condition. The floor area shown on the Mining Plan Map covers 20 acres and initial movement of the mine face creating the first 4 benches. However, by the time this 20.0 acres is established the first 40 foot bench/face will have been opened so the analysis can be done. We propose limiting the disturbance to 20.0 acres and doing the initial study when the first 40 foot cut is complete. This should expose enough rock to determine the necessary geotechnical conditions on the site. if needed at this time the mining and reclamation plans can be revised to assure the faces will be stable during mining and reclamation without causing any delays to mining.
