Structure Description/notes Owners H. Highway, related US-160 (State Highway 160) is a 25-foot paved two-lane highway with paved CDOT features, and utilities shoulders. Various utilities are located within the right-of-way, including Empire Electric Assn. electrical and communications lines. The entrance road to the permit area Qwest includes decorative fencing and gate, and is partially paved. The right-of-way is fenced. A culvert under the highway is located approximately 300 feet to the west. The entire right-of-way is more than 500 feet from the affected land. Improvements to existing Access Road A are located more than 200 feet from the right-of-way. Evaluation The highway is built on engineered fill and has adequate drainage in both directions. Proposed mining activities, and improvements required by CDOT to access road entrance will not impact the highway and are located outside the permit area in the right-of-way. (Refer to access permit and application.) Gate is stable, adequately supported and constructed, and has adequate height and width for truck traffic. No overhead utilities lines must be relocated to provide safe clearance. Improvements to the roadway are of such a nature that there is no reasonable expectation of any damage or other impact on existing utilities or US-160. Although Road A will be improved, that portion of Road A within 200 feet of the right-of-way line of US- 160 requires no improvements that would meet the definition of "affected area" and therefore we , believe that no agreement with either CDOT or the utilities companies with structures located within the right-of-way are necessary. Even if this portion of Road A had significant improvements, there is no work which would be required that would have any impact whatsoever that might be considered by the engineer to threaten any geotechnical stability of the road or other structures in the right-of-way. Note: Portions of Access Road A in the affected area. Improvements to this road are based on requirements from CDOT for the Access Permit to US-160 which was issued by CDOT approximately 6 months ago, and required by any change in access use for commercial purposes (not just mining), and therefore, improvements are subject to a separate state-issued permit and therefore not subject to a mining and reclamation permit. Conclusion and These structures will not be damaged by proposed operations, based on distance from affected lands. recommendations Access improvements must be completed and accepted by CDOT prior to beginning full-scale mining operations. No action required. Structure Description/notes Owners J. The Hogan trading This is a commercial business (a trading post) with a large central building, Countess, Wm D & post and associated parking, landscaping, utilities, and several secondary buildings. It is located Judy M. structures approximately 500 feet from the affected land. All portions are more than 200 38651 US 160 feet from affected land. Evaluation Proposed mining and final grade slopes to match to undisturbed land in the buffer zone will adequately protect this property from any damage due to mining operations. The terrain and the distance from affected land protect these permanent structures from any significant physical impact. The south buffer zone was laid out in part to ensure that there was no impact on this property. All operations are downslope. Conclusion and These structures will not be damaged by proposed operations, based on terrain and distance from recommendations affected lands.
