undermining of approximately four (4) miles of Routt County Road No. 33. These four miles of road lie within the area affected by longwall panels 9R, 8R, 7R (PR-03), 6R and SR (PR04). There was no public response or concern voiced about undermining of the road. The applicant received all necessary approvals from Routt County to undermine County Road No. 33. Special Use Permit No. 92-233 issued by Routt County approved the undermining and subsidence of County Road No. 33 as long as the conditions addressing appropriate road warning signage, monitoring, and repairs are met by Twentymile Coal Company. Based on the above information, the Division finds Twentymile Coal Company in compliance with Rule (2.07.6(2)(d)(iv)) for the undermining of Routt County Road No. 33. Approval of PR-04, April 20, 1998, allowed for continued mining in the Eastern Mining District of Longwall panels 6R through 2R. Only panels 6R and SR had an impact to Routt County Road No. 33. Experience gained during subsidence of panels 9R through 7R demonstrated that traffic on County Road No. 33 was not interrupted as a result of the subsidence of the road. Subsidence of Longwall panels 6R and SR did not interrupt traffic on Routt County Road No. 33. Approval of PR-OS allowed longwall panel 12 Right to undermine a Twentymile sandstone outcrop in Section 14, TSN, R86W. Prior to approval TCC demonstrated there was a very slight potential for rock from this outcrop to reach Routt County Road 33 as a result of the undermining. TCC committed to scaling loose rock on the slope prior to undermining, using concrete barriers along the north side of Routt County Road 33 (as necessary), and draping chain link mesh over the outcrop. Mining proposed in PR-06 is more than one-quarter mile from public roads h) Three hundred feet of an occupied dwelling unless a written waiver from the owner has been provided. TCC successfully complied with Stipulation No. 36 for the Southwest Mining District on March 25, 1994 for the mobile home owned by Mr. Robert Perry. Three dwellings were undermined in the Eastern Mining District (Longwall Panels 6R-2R) during 1999. One had been occupied year round, one was vacant and is owned by Twentymile Coal Company, and the third was occupied only during portions of the yeaz. Twentymile Coal Company has a subsidence agreement with Mr. Kenneth Ashley regarding his dwellings. (2.07.6(2)(d)(v)). The full-time residents were moved by Twentymile Coal Company to alternative accommodations prior to subsidence of the house. Twentymile Coal Company took precautions with the home by bracing floor joists and door frames prior to undermining. The house was located near the center of Longwall panel 5 Right. After subsidence occurred, Twentymile Coal Company and the Ashley's agreed upon mitigation of the house by replacement of the structure. Twentymile Coal Company demolished the original structure, backfilled the foundation, constructed a new foundation and installed a modular home as agreed upon with the landowner. The smaller residence owned by the Ashley's overlay gateroad 6 Right, and experienced roughly 4 inches of subsidence. Twentymile Coal Company conducted repairs to the smaller residence in accordance with the subsidence agreement with the Ashley's in the fall of 1999. The residence owned by Twentymile Coal Company also overlay gateroad 6 Right. This structure was not monitored for subsidence impacts and will not undergo any mitigative measures as a result of subsidence. 5. On the basis of information obtained from the State Historic Preservation Office (SHPO) and archeological and cultural resource surveys submitted by the applicant, the Division finds that subject to valid existing rights as of August 3, 1977, the mining operation will not adversely affect any publicly owned pazk or place listed on or eligible for listing in the National Register 15
