JAMES A.BECKWITH FONTANARI OBJECTIONS AND COMMENTS I SNOWCAP BOND APPLICATION SL-1 I I PG.8 Subsidence Event B 1 Tract No. 71 Central This subsidence depression is situated wholly within the boundaries of Tract No. 71, and situated just east of Snowcap's repair project area. It was documented via GPS; photographs; and survey plat in Mr. Eldridge's 2016 and Updated 2016 survey plats: both of which were submitted to DRMS in Docket No. TR-69 together with the photographs of the depression and sinkholes. This depression has numerous sinkholes along its northern boundary, which is situated generally along the south face of the historic rock wall. In 2018, Fontanari dug a 2 feet deep trench along the southern face of the rock wall in preparation for installation of a 10" irrigation pipeline. This is part of his project to mitigate damages caused by coal mine subsidence. The digging destroyed the stakes identifying the locations of the sinkholes. A copy of the photographs of the depression and sinkholes is contained in Fontanari Exhibit 8. This depression is 100 feet long; 45 feet wide and, 5-7 feet in depth. Subsidence Event C 1 Tract No. 71 East On August 15, 2018, the DRMS Inspection Team resumed its transect of Tract No 71, starting at the approximate center of the tract. At Fontanari's request, Mr. Wein logged and photographed various points. These included Subsidence A and Subsidence B depressions; sinkholes on the adjacent Carey property, and sinkholes on the north side of the historic rock wall in Tract No. 71. In addition, Mr. Wein logged SCP 1027 (found among stored tree trunks) and an unlabeled tetrahedron also found among stored tree trunks. Tonya Hammond, Snowcap's agent, claimed that the location of the unlabeled tetrahedron was also the location of a monitoring well. However, such a monitoring Well has never been identified by either Powderhorn Coal Company or Snowcap in any of the 1987-2018 Annual Hydrologic Reports filed with DRMS. While transecting Tract No. 71, a large surface subsidence trough was found at the tract's eastern edge. Sinkhole lines were found on the eastern rim of this trough by DRMS representatives Messrs. Hernandez and Bowles. On August 16, 2018, Mr. Eldridge returned to Tract No. 71 to GPS, log, and take elevations of the rim and crater of this trough. (Fontanari Exhibit 13) On August 24, 2018, photographs were taken of the trough and the sinkhole areas. (See Exhibit 9.) Subsidence Event D 1 Tract No.35 On August 14, 20181, the Fontanari team advised the DRMS inspectors of a potential subsidence depression in the North Decline. On August 24, 2018, Mr. Eldridge, PLS 119809 6 A brush fire along I-70 next to the Colorado River had interrupted the August 14th transect. 7 "SCP"—Subsidence Control Point as identified on the 1980 GEX Mine Map.
