The approximate dimensions of the Extraction Site (including excavation area, stockpiles, etc.) <br /> are shown on Exhibit C-1. <br /> (g) Road Dimensions: <br /> The dimensions of the Existing Access Road are shown on Exhibit C-1. This road will not be <br /> included in the permitted acreage as it is a pre-existing structure and will remain for the <br /> landowner's use after mining. There will be no new drainage and runoff conveyance structures <br /> associated with the Existing Access Road. <br /> (h) Operation Water Use: <br /> As necessary, Applicant will purchase water for dust suppression and other nonsubstantive <br /> industrial uses on the site. Applicant estimates that it may use approximately 2000 gallons of <br /> water per operating day for these purposes when mining and or trucking is occurring. <br /> (i) Groundwater/Surface Water Disturbance: <br /> Groundwater will not be exposed by the mining activities. The Applicant expects that there will <br /> be no impact to groundwater from the proposed operation. In addition,the proposed operation <br /> will not result in any impact to surface waters. Stormwater runoff from disturbed areas will drain <br /> into the gravel pit and will seep into the ground within 72 hours. The gravel pit floor will be <br /> graded as extraction occurs at a 1-2% slope in order to direct runoff into the bermed sediment <br /> trap at the southeastern end of the Extraction Site. Applicant plans to manage storm water by <br /> utilizing best management practices based on guidance from the Colorado Department of <br /> Transportation Erosion Control and Storm Water Quality Guide.' Sediment transport from storm <br /> water will be minimal. Management practices can be found in Exhibit C-2, Storm Water <br /> Management Plan. - <br /> 0) Existing Water Rights: <br /> Existing water rights will not be affected by the mining activities. <br /> (k) Refuse and Acid or Toxic Materials: <br /> There are no known refuse, acid, or toxic-producing materials in the area of the proposed gravel <br /> pit. If they are encountered,operations will cease and the materials will be contained in <br /> accordance with applicable laws and regulations. <br /> (1) Measures to Minimize Disturbance to Hydrologic Balance, Off-Site Damage, and <br /> Provide for a Stable Configuration of the Reclaimed Area Consistent with the Proposed <br /> Future Land Use: <br /> 1 https://www.codot.gov/programs/environmental/water-quality/documents/erosion-storm-quality. <br /> Burton Farms LLLP Page 4 of 5 <br /> Construction Materials Limited Impact(I 10(c))Operation Reclamation Permit Application Form <br />
