7) CR88 (Shelf Road) owned by Teller County <br /> This two lane dirt road is immediately east of the permit boundary but is within the 200 feet <br /> boundary for the affected area boundary. However, as is seen on Map C-la, the mine facilities <br /> that could affect the road, such as pit excavations, embankments, overburden or topsoil <br /> stockpiles, are well away from the Road to possibly adversely affect it. The closest mine facility <br /> to the road is the toe of the Squaw Gulch VLF, which lies to the east at a distance of 2000 feet. <br /> This VLF has been properly designed and it is too far away to affect the Shelf Road(Teller <br /> County Road 88). The Squaw Gulch VLF stability is evaluated for Structure 8 —Colorado <br /> Highway 67. <br /> 8) Colorado HWY 67 including bridge owned by CDOT <br /> This State I I ighway is a two lane paved road maintained by the Colorado Department of <br /> Transportation. It is the main road connecting Cripple Creek and Victor. This Road is within the <br /> permit boundary and affected area boundary in certain segments and is also very close to the <br /> Squaw Gulch Valley Leach Facility (VLF), as well as the toe of the Arequa VLF. This is seen on <br /> Map C-la. This road also includes a tall bridge above the original drainage of Arequa Gulch. <br /> Since Highway 67 is within 150 feet of both VLF's, both are evaluated for their long term slope <br /> stability. These evaluations are given below. <br /> Evaluation of Arequa Gulch Valley Leach Facility (AGVLF) <br /> This Valley Leach Facility is a lined leach pad where an impermeable liner was placed in the old <br /> Arequa Gulch valley, which was then filled with crushed ore and allowed to leach to extract the <br /> gold in solution, which is then recovered in a lined pond at the plant at the toe of the facility. The <br /> crushed ore is placed in 100 feet tall lifts at a maximum angle of approximately 1.31-1:LOV, <br /> followed by a horizontal bench of approximately 30 feet. Places along the perimeter of the pile <br /> are as mild as 2.OH1.OV. The crushed ore is generally less than 3/4 inch in size although some <br /> larger sizes may exist in small quantities. As of the end of 2016, no more ore material will be <br /> added to the facility but it will continue leaching for approximately 7 years, after such time the <br /> facility will be reclaimed in place. <br /> The original design and slope stability evaluation was done for the original permit in 1993 and <br /> was modified a number of times. The AGVLF began construction in 1994. Phases I and II were <br /> constructed from 1994 to 1996. The Phase III design was submitted in 1998 and, after approvals, <br /> was completed in 2000. Phase IV was approved in 2000, and was completed in 2004. The Phase <br /> 33 <br />
