<br />Pit A is presently being mined in the North 1/3 with stripping being <br />done in the center 1/3. Mining in the pit is done in benches ranging from <br />10' to 36' in height. When the North 1/3 is mined out, the waste and excess <br />material from the South 2/3 will be placed in the open excavation. At <br />present, waste and excess material is hauled south across the county line <br />road to fill in a low swampy area. Water seepage into the pit is utilized <br />in dust control with the excess being pumped into the Highland Ditch which <br />feeds the foothills Reservoir. This water then reverts back to the origi- <br />nal destination of flow. <br />Pit B is presently being mined with approximately 25 percent ore re- <br />maining. The northern 3/4 have been mined. This area is used for plant <br />waste disposal. The plant waste is dust. Approximately 25 percent is <br />under reclamation at the time. 4Jaste and excess material is removed from <br />the top of the ore body and placed into an area to the southwest of the pit. <br />This is a low lying area that will be leveled up to make more suitable <br />pasture or cropland. The Boulder Feeder Canal and the Staede Ditch is pro- <br />posed to be relocated into the mined-out area of Pit B. <br />During the ditch relocation project, Pit D will be mined. The method <br />of mining will be the same as for Pit B with the exception that the waste <br />material will be put into the mined-out area of Pit B. This pit protrudes <br />• and makes a sizable knob. When mining is complete, the knob will be leveled <br />off to make suitable pasture or cropland. <br />While mining is taking place in Pit D, stripping and development will <br />take place in Pit C. Development will start on the west side and proceed <br />to the east. Initial stripping will be put into Pits B and D. Once the <br />ore has progressed far enough to the east, the stripping material will be <br />placed into the mined-out area of Pit C. When this stage is reached, <br />reclamation will proceed right along with the mining operation. <br />From Pit C, the mining operation will proceed to Pit E. Overburden <br />and waste material will have to be stockpiled or moved to Pit C to begin <br />with. After enough ore is removed, overburden and waste material can be <br />placed into the mined-out area and reclamation will closely follow the <br />mining operation. This pit will complete the high grade limestone mining <br />operation. <br />Pit F will be mined in conjunction with Pit E. This pit is a continu- <br />ation of Pit A and will be mined like Pit A. Initial stripping and waste <br />material will be placed into Pit A. The remaining overburden and waste <br />material will be used to backfill the mined-out area of the pit. This pit <br />will complete the low grade limestone mining operation. <br />To get the proper perspective,one must observe the timetable, the <br />mining plan, and the pit and reclamation maps at the same time. Due to the <br />. continuous operation, it is impossible to portray on any one map a single <br />phase or a number of phases. <br />
