JAMES A. BECKWITH <br />LETTER TO BROCK BOWLES, CO DRMS / SNOWCAP COAL COMPANY RECLAMATION / PG. 10 <br />First, from 1981 to 2003, the lands at issue were owned by Powderhorn Coal Company or <br />Snowcap itself. Neither of these entities planted surface crops to prevent erosion. Both these <br />entities allowed the surface to "go to seed", as it were. In 1989, Powderhorn Coal Company <br />demanded cessation of irrigation on the Carey and 71 Tracts because sinkholes and sub -surface <br />fissures caused by the mining activities in these tracts were allowing the irrigation water to enter <br />the active mine chambers. Second, agricultural pursuits require water and irrigation. Efforts to <br />irrigate in 1989, and 2014, resulted in immediate and complete loss of irrigation water due to <br />sinkholes caused by Snowcap's collapsed mining caverns. Third, in the period 1880-1900, the <br />lands were owned and cultivated in orchards by Mr. George Crawford: founder of Grand <br />Junction. Fourth, aerial photos taken September 11, 1937 showed extensive orchard cultivation <br />of Tracts 71 and the Carey property. [Appendix N] Fifth, aerial photos taken in 1954 aerial <br />photo (from Mesa County GIS website) also showed continued cultivation of orchards in the <br />area. [Appendix O] Sixth, none of the water rights applicable to the Fontanari and Carey lands <br />have ever been determined to be "abandoned". But for Snowcap's sinkholes and subsurface <br />fissures, Fontanari and Carey would be farming surface crops of some relevant type at present. <br />The absence of current agricultural pursuits on Tract 71 can be set entirely at the feet of <br />Powderhorn and Snowcap coal companies. Roof and pillar collapses have created sub -surface <br />fissures and cracks and surface sinkholes. Application of irrigation water to the surface causes <br />the immediate loss of that water. To grow agricultural crops on the surface, Fontanari must <br />install cast iron pipe in all transmission ditches. This prevents water loss caused by subsidence <br />and sinkholes. Fontanari must then select a crop which the damaged condition of the land will <br />allow to be irrigated without losing the water. For example, Tract 71 would accept orchards <br />which can be irrigated by the drip system. The drip system localized water application and <br />prevents down -sinkhole loss associated with flood and sprinkler irrigation. <br />(E) Snowcap Does Not Accept HBET's Recommended Repair Plan <br />HBET recommends 25 ft deep excavations within a 100 foot radius of the air ventilation <br />shaft. After such digging, HBET recommends installation of compaction grouting to "plug" the <br />anomalies in the belief this will stop the loss of surface irrigation water. [Pgs. A-14-14-3] Each <br />grout hole will be more than 25 ft. in depth. [Id] There will be two sets of holes: primary and <br />secondary. Primary holes will be spaced 10-20 feet apart in a grid pattern. [Id] Secondary holes <br />would be half -spaced between the primary holes. [Id] This would constitute 50 +/- holes and <br />plugs within the 100 ft. radius. HBET then recommends even more grout holes around each <br />sinkhole: presumably, the irrigation ditch and the rock pile. [Pg. A14-14-4] Finally, HBET <br />recommends yet more grout compaction holes to "map" the pathways to the air ventilation shaft. <br />HBET does not make any other recommendations. [Id] Notably, HBET does not recommend <br />any action for the Carey Pond. Perhaps, this is because there was no identifiable connection <br />between the Carey Pond and any other surface subsidence. <br />HBET acknowledges that compaction grouting within grid pattern holes is "more <br />expensive that excavation...". [Id] Perhaps, for financial reasons only, Snowcap rejects HBET's <br />proposal and, instead, states it will dig only two holes: one at the air shaft and one 25 ft. <br />northwesterly from the air shaft. Each excavation will be only 16 feet deep and will be flared to <br />
