OVERVIEW OF AMENDMENT Loveland Ready Mix Concrete, Inc. is applying for an amendment to our mining permit #M-1974-069 in order to implement an augmentation plan. The revised mining and reclamation plan will incorporate the lining of two ponds, which will be used for yeaz- azound storage and return for augmentation water. The two lined storage ponds will not expose groundwater surface that would require augmentation to replace evaporative loss. In general, the mining plan remains essentially the same. The same area we originally planned to mine will still be mined. The difference is that mining cells 4 and 5 will be combined into one cell and mining cells 6 and 7 will be combined into another cell. The reclamation of these two combined mining cells will be lined with an impervious liner in accordance with the design by Earth Engineering Consultants. The result will be the construction of two water storage ponds in the area immediately west of Namaqua Road (CR 19E). Storage Pond #1 will be constructed from mining cells 4 and 5 and Storage Pond #2 will be constructed from mining cells 6 and 7. We have filed an augmentation plan with the water court. This plan outlines storing water in the newly constructed storage pond and releasing it back to the river each month as required to meet the augmentation depletion demand. The water supply for the plan will be a new storage decree for 550 acre-feet and a change of use decree for 120 inches of Barnes Ditch water that Loveland Ready Mix owns. This stored replacement water will provide augmentation water for the Larimer Pits and for other existing and future mining operations. The revised reclamation plan also includes backfilling some of the existing pond areas to reduce the exposed groundwater surface area requiring augmentation. We plan to mine cell 9 before cell 8 and partially backfill it with excess overburden and inert fill materials. )n general, the overall mining and reclamation plan will follow the original plan with the exceptions noted above. Details of the proposed amendment aze included in the following exhibits. The current status of the site has cells 4 & 5 lined and reclaimed forming Storage Pond #1. Cells 6 & 7 are 90 to 95 percent mined and the lining is 60 to 70 percent complete and some reclamation has been completed. No activity has occurred on mining cells 8 and 9. Our proposed amended mining, reclamation, and augmentation plans together with supporting documents are described in the fogowing plans and narrative and constitute the requested amendment.
