�r ;IVL <br /> a T ransit Mix Concrete Co. <br /> ,L <br /> EXHIBIT G <br /> 64) On page G-4, the Applicant refers to Exhibit E for more details on the reclamation drainage <br /> in the quarry area. However, very little information about this drainage is provided in <br /> Exhibit E. Please provide more details on all proposed drainages to remain for reclamation <br /> in either Exhibit E or G. Additionally, please provide clarification on how the locations of <br /> these drainages were chosen. <br /> Response: A discussion on the reclamation drainage network and the reclamation of <br /> stormwater management structures has been included in Exhibits E and G. <br /> 65) On Table G-2A, the value given for Phosphorus under 6/16/15 Results is 110 mg/L. <br /> However, the Segment 14d Standard for Phosphorus is 0.11 mg/L. Please explain or correct <br /> this error. <br /> Response: Table G-2A has been revised to report the correct Phosphorus value of 0.11 <br /> mg/L. <br /> 66) On page G-26, the Applicant states that water will most likely be purchased from Colorado <br /> Springs Utilities with water hauled from Colorado Springs and stored on site. Please <br /> provide an estimate of the project water requirements including flow rates and annual <br /> volumes for the development, mining, and reclamation phases of the project. <br /> Response: Transit Mix estimates that the operation will require varying amounts of water <br /> depending on the time of year and weather. Water will be hauled from Colorado Springs <br /> on an as-needed basis; Transit Mix estimates this will require an average of 4 to 6 <br /> truckloads per day using a 6,000 to 7,000-gallon tanker truck. Transit Mix plans to install 2 <br /> cisterns to hold water hauled from Colorado Springs: 1 — 5,000-gallon cistern at the scale <br /> house and 1 — 15,000-gallon cistern or tank at the plant site. <br /> 67) On page G-27, the Applicant states the 2017 drilling program identified the existence of <br /> saturated groundwater conditions within the granodiorite rocks above the level of Little <br /> Turkey Creek. Please expand the discussion, providing more details about these saturated <br /> conditions. Does the Applicant believe these conditions to represent the groundwater table <br /> for this area? <br /> Response: Section 3.2 of Attachment G-2 has been revised to expand on the discussion of <br /> saturated groundwater conditions in the quarry area. Potentiometric data indicate that <br /> saturated groundwater conditions exist in the granodiorite rocks of the South Ridge, where <br /> the proposed quarry will be located, above the elevation of Little Turkey Creek. Figure 3-2 <br /> of Attachment G-2 shows the distribution of potentiometric head elevations, that closely <br /> represent the water table. These are also shown on Figures C-11 and C-12. Within the <br /> quarry footprint, saturated conditions range from zero to 250 feet above the level of <br /> adjacent Little Turkey Creek and range from zero to 200 feet below ground surface. <br /> Hitch Rack Ranch Quarry(M-2017-049) <br /> Response to Comments—March 9,2018 <br />
