JAMES A. BECKWITH <br />FONTANARI OBJECTIONS AND COMMENTS / SNOWCAP BOND APPLICATION SL -I I / PG. 8 <br />Subsidence Event B / Tract No. 71 Central <br />This subsidence depression is situated wholly within the boundaries of Tract No. 71, and <br />situated just east of Snowcap's repair project area. It was documented via GPS; photographs; <br />and survey plat in Mr. Eldridge's 2016 and Updated 2016 survey plats: both of which were <br />submitted to DRMS in Docket No. TR -69 together with the photographs of the depression and <br />sinkholes. <br />This depression has numerous sinkholes along its northern boundary, which is situated <br />generally along the south face of the historic rock wall. In 2018, Fontanari dug a 2 feet deep <br />trench along the southern face of the rock wall in preparation for installation of a 10" <br />irrigation pipeline. This is part of his project to mitigate damages caused by coal mine <br />subsidence. The digging destroyed the stakes identifying the locations of the sinkholes. A <br />copy of the photographs of the depression and sinkholes is contained in Fontanari Exhibit 8. <br />This depression is 100 feet long; 45 feet wide and, 5-7 feet in depth. <br />Subsidence Event C / Tract No. 71 East <br />On August 15, 2018, the DRMS Inspection Team resumed its transect of Tract No 71, <br />starting at the approximate center of the tract.6 At Fontanari's request, Mr. Wein logged and <br />photographed various points. These included Subsidence A and Subsidence B depressions; <br />sinkholes on the adjacent Carey property, and sinkholes on the north side of the historic rock <br />wall in Tract No. 71. In addition, Mr. Wein logged SCP 1027 (found among stored tree <br />trunks) and an unlabeled tetrahedron also found among stored tree trunks. Tonya Hammond, <br />Snowcap's agent, claimed that the location of the unlabeled tetrahedron was also the location <br />of a monitoring well. However, such a monitoring well has never been identified by either <br />Powderhorn Coal Company or Snowcap in any of the 1987-2018 Annual Hydrologic Reports <br />filed with DRMS. <br />While transecting Tract No. 71, a large surface subsidence trough was found at the tract's <br />eastern edge. Sinkhole lines were found on the eastern rim of this trough by DRMS <br />representatives Messrs. Hernandez and Bowles. On August 16, 2018, Mr. Eldridge returned to <br />Tract No. 71 to GPS, log, and take elevations of the rim and crater of this trough. (Fontanari <br />Exhibit 13) On August 24, 2018, photographs were taken of the trough and the sinkhole <br />areas. (See Exhibit 9.) <br />Subsidence Event D / Tract No. 35 <br />On August 14, 2018, the Fontanari team advised the DRMS inspectors of a potential <br />subsidence depression in the North Decline. On August 24, 2018, Mr. Eldridge, PLS 11980, <br />6 A brush fire along I-70 next to the Colorado River had interrupted the August 14th transect. <br />7 "SCP" — Subsidence Control Point as identified on the 1980 GEX Mine Map.
