<br /> <br />other relevant facts that should be considered by the Board and that the petition explain <br />why airy new facts were not available at the original hearing. <br />Haldorson's Petition and Supplement and the Exhibits and Appendices attached to <br />each respectively, meets this standard for the following information in particular: <br />• The applicant is requesting permission to begin mining to a depth of 13 feet (3 <br />feet of topsoil and 10 feet of gravel), instead of committing to a maximum <br />depth of 20 feet, prior to the year's worth of groundwater level data; <br />• Irrigation water enters the aquifer on the terrace through a network of irrigation <br />channels, and travels down to the Mancos Shale, then flows along the dip of the <br />shale to the lower terrace floodplain of the river and enters the river system; <br />• It is likely that no groundwater exists on the mesa once irrigation ceases and the <br />gravels are allowed to drain (based on observations of similar areas in western <br />Colorado); <br />• Groundwater levels on the mesa are a function of gravel porosity and <br />permeability, the dip of the shale bedrock, the amount of water entering the <br />system, proximity of the infiltration water, and other factors; <br />• The Mancos Shale at the site dips to the northeast at between 1% and 5%; <br />• The 6 test holes dug in March of 2003 showed the depth of the gravel and the <br />strike and dip of the shale; <br />• Based on the author's experience, the conditions at the site and the proximity of <br />the imgation would result in water levels of only 5 to 6 feet above the shale <br />layer; <br />• An inspection of the mesa slope revealed no evidence of phreatophyte <br />vegetation, nor salt deposits that may be an indication that water had emanated <br />from the slope face; <br />• The only phreatophyte vegetation at the site -cottonwoods, willows, and water- <br />demanding grasses - is located within a few feet of the slope toe; <br />• The highwall of the Metcalf Pit, located west of the proposed site on the slope <br />edge of the upper terrace, has no history of groundwater emanating from it; <br />• The Spring Creek Mesa Pit located in the same gravel terrace deposit as the <br />proposed Haldorson Pit, and only 2/3 mile from Phase I, has mined to 30 to 35 <br />feet below ground surface, and groundwater has never been encountered; <br />• A test hole dug to approximately 60 feet at the Spring Creek site, during <br />irrigation season, never encountered groundwater; <br />• The Applehanz Base Products Pit, immediately east of the Spring Creek <br />operation was excavated to a depth of 40 feet below ground surface and has <br />never encountered groundwater; <br />• The reclaimed topography at the site will not affect surface runoff at the site <br />due to the minimal amount of precipitation at the site coupled with the aridity of <br />the climate. <br />
