III. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. previously for the Coal Creek road and powerline). Workings were located beneath segments of Jerry Creek along a reach extending from the SE ~/a Section 20 downstream across Section 21, and a lower segment of Jerry Creek was undermined by workings in the NE Ya of Section 27. The lower segment of Jerry Creek that is within the release request area was inspected by the entire group in conjunction with the inspection along the Government Highline Canal. I walked the entire length of Jerry Creek that was potentially subject to subsidence damage, from the SE ~/a Section 20 downstream to the canal, and also checked the potentially affected segment of Coal Creek in the NW'/a of Section 28. Jerry Creek was carrying a small flow of silty runoff at the time of the inspection; Coal Creek was dry. Both streams are dry much of the year, and flaw primarily in response to precipitation events. These streams are located in asemi-desert, canyon environment. Moderately sinuous, "C" type channels with sandy substrates predominate. The streams do not support significant riparian communities, although stands of salt cedar have become established along some reaches of Jerry Creek, and greasewood communities along both drainages benefit from occasional over-bank flows during flood events. No areas of settling or cracking were observed along the stream reaches described, in or adjacent to the channels, that would possibly be related to mine subsidence. Any linear surface features observed adjacent to the channels were found to be rills or gullies caused by storm runoff from the steep, rocky, relatively barren canyon slopes. Man-made Structures-South Portals Area Two residences including a house constructed on the Sample property in 2004 and a house and shop constructed on the Edmonds property in 2007, both located in the NW'/< Section 1, are included in the bond release request area, and mining occurred beneath both properties at least 7 years prior to construction of the structures. The properties were viewed from adjacent roads during the inspection, and no obvious subsidence related features were observed. Owners of both properties had been notified of the bond release request and associated inspection, but neither party had contacted the Division with subsidence concerns or to request a site inspection. For this reason, the private residential structures were not closely scrutinized for possible subsidence features or damages during the bond release inspection. Additional structures described in permit text and depicted on the Man-made Features Map (Exhibit 46), which are included within the bond release area, include two buried raw water pipelines owned and maintained by the City of Palisade, which supply the Palisade water treatment plant located west of the permit area, and the Colorado-Ute 345KV transmission line constructed across the eastern portion of the South Mine Area, in 1985. The Palisade water lines are located along the Rapid Creek and Cottonwood Creek valleys, and both structures have been undermined. The 345KV transmission line has not been undermined; workings are located approximately 2000 feet from the nearest support tower (Tower #207). Calculated zone of subsidence influence would extend approximately 483 feet horizontally, based on the approved angle of draw for Roadside Portals Mine (12 degrees) and maximum (worst case) mining depth of 2300 feet in the South Portal Area. Substitution of an extremely conservative 25 degree angle of draw results in a horizontal distance of 1081 feet. Other structures included within the bond release request area include sections of the TransColorado Gas Pipeline and a second Colorado Ute Transmission Line, both of which are located in the extreme southeast corner of the permit area in Section 18, more than a mile removed from the nearest mine workings. Due to the fact that the gas pipeline and transmission tower structures are well outside the potential subsidence angle of draw, the structures were not inspected, although a segment of the 345KV powerline that crosses over the Rapid Creek Valley was viewed from a distance, from a vantage along the Rapid Creek Road. Inspection of the Palisade raw water pipelines was conducted, to the extent a buried pipeline can be inspected, by slowly driving along the Rapid Creek and Cottonwood Creek Roads, which closely parallel segments of the pipeline. No apparent subsidence cracks, settlement, or other features indicative of surface subsidence were observed along the roads or adjacent areas.
