Transit Mix Concrete Co. <br /> submitted with the application, these wells are described as being located within the <br /> proposed permit boundary. Please correct the locations for these two wells. <br /> Response: Figures C-I I and C-12 have been updated to include all the monitoring wells, <br /> and the wells have been adjusted to the correct locations. <br /> 37) In Figure C-12, on the Insert Plan View, Little Turkey Creek is located approximately 300 <br /> feet from the northern pit crest on section line C-C'. However, on the C-C' cross-section, it <br /> appears the northern pit crest is located approximately 200 feet from Little Turkey Creek. <br /> Which is the correct distance at that location? Please revise the cross-section and/or inset so <br /> that they are consistent and correct. Additionally, please provide clarification on whether <br /> the proposed operation intends to mine into the Little Turkey Creek fault zone. (The pit <br /> outline is difficult to make out on this cross-section due to the patterned background and <br /> other features present at that location.) <br /> Response: Figure C-12 has been updated to clearly show the locations of the pit crest, <br /> Little Turkey Creek, and the fault zone. Transit Mix does not intend to mine into the fault <br /> zone along Little Turkey Creek as this zone is located immediately adjacent to and below <br /> the creek and within the 100-foot setback. <br /> 38) For Figure C-12,please clarify the purpose of cross-section D-D'. <br /> Response: Cross-section D-D' was included on Figure C-12 to show the groundwater <br /> conditions in the sandstone aquifer east of the project area. <br /> 39) On Figures C-4 through C-8, please add the proposed 100-foot mining setback from Little <br /> Turkey Creek. <br /> Response: Figures C-4 through C-8 have been revised to include the 100-foot mining <br /> setback from Little Turkey Creek. <br /> EXHIBIT D <br /> 40) On page D-2, the Applicant states that final development elevations will remain a <br /> minimum of 10 feet above the level of Little Turkey Creek. Please also confirm the pit <br /> floor will remain a minimum of 10 feet above the thalweg of Little Turkey Creek during <br /> mining operations. <br /> Response: Correct. The pit floor and drainage control structures will remain at least 10 <br /> feet above the thalweg of Little Turkey Creek during mining operations and for closure. <br /> The only exception to this limit is the discharge pipe and channel connecting the pit area to <br /> Little Turkey Creek. Connecting these water conveyance structures requires disturbance to <br /> the creek highwater line. <br /> 41) On page D-3, the Applicant states that prior to commencing mining.... mining crest limits <br /> and affected lands boundary will be GPS surveyed and staked to delineate mining activity <br /> Hitch Rack Ranch Quarry(M-2017-049) <br /> Response to Comments—March 9,2018 <br />
