Mr. Bob Oswald Division of Minerals & Geology March 2, 1994 Page 3 10. Reclamation Map needs to show information on the applicant's best proaection of the extent of necessary recla- mation ofi fiinal contours, site drainage, stockpile locations. Present reclamation pro,iections are for a 3H:1V slope on the north perimeter to a level pit floor with approximately a 1% slope toward the south. The pit is proposed to daylight at the south perimeter. Site drainage will follow the 1'/. slope to the south, which will be flat enough to slow surface run- off. There will be no stockpiles when reclamation is complete. il. Exhibit G states the applicant has covered this op- eration's need for acquiring a NPDES permit through a Brick Institute ofi American Group Stormwater Discharge Permit *1024. Does this mean that the pit would otherwise require a NPDES Permit. It is this consultant's experience that this operation would not require a NPDES Permit. However, with the Federal Clean Water Act and Colorado's response in the Stormwater Discharge Permit requirements, it appears that only a Stormwater Dis- charge Permit permit will be required in this instance. 12. Reclamation costs should reflect any mobilization/ demobilization of equipment. This item was calculated at X600, based on moving equipment from Colorado Springs and was included in the Indirect Costs. If equipment could be leased in the Calhan area, this cost would be lower. The bond is calculated on a maximum of IOA, but the mining and reclamation plan will probably never af- fect that much at any one time. 13. Exhibit R must include proof of receipt of the notifica- tions sent to the County and SCD. Signed return receipts are an example of what is acceptable. Please provide this. My records indicate that the Paid receipt for mailing and signed Return Receipt have already been sent. If you do not find them, let me know and I will send another copy.
