Transit Mix Concrete Co. <br /> 81) On page H-5, under Mitigation Measures, the Applicant states that no mining will occur <br /> within 100 feet of Little Turkey Creek besides construction necessary to create the <br /> reclamation channel discussed in Exhibits G and F. The Applicant then states that any <br /> development or surface disturbance within this 100-foot setback will be minimized to the <br /> extent possible and will only occur where necessary for mining operations. Please explain <br /> this contradictory language, clarifying the type of development or surface disturbance <br /> (other than the drainage mentioned) that might occur within the 100-foot setback. <br /> Response: The text in Exhibit H has been revised to more clearly discuss that disturbances <br /> within the 100-foot setback are limited to the discharge pipe from the Plant sediment <br /> detention basin and the reclamation channel. The pipe and the channel will have the same <br /> alignment and discharge to Little Turkey Creek in the same location to minimize <br /> disturbances in this area. No other surface disturbances are planned within this 100-foot <br /> setback; however, should a disturbance be required, it will be minimized to the extent <br /> possible and will only occur where necessary to support mining operations. All <br /> disturbances will remain within the affected lands boundary. <br /> EXHIBIT L <br /> 82) On page L-4, Table L-1 includes 20.41 acres of highwall slopes to be reclaimed for mining <br /> phase III, and Table L-2 includes 20.41 acres of highwall slopes to be revegetated for <br /> mining phase III. However, the application states that highwall slopes will not be <br /> reclaimed. Please explain why highwall slope acreage is included in these tables. If <br /> highwall slopes will not be reclaimed, these areas need not be included in reclamation <br /> acreages (only in affected land acreages in Exhibit D). <br /> Response: The highwall slopes will remain as bedrock outcrop faces and will not be <br /> revegetated, and the highwall slope acres have been removed from the revegetation area <br /> calculations in Exhibit L to address this comment. <br /> 83) On page L-4, Table L-1, please explain the category of Pit Floor/Stockpile Tops, which <br /> totals 36.17 acres. Why are these two features combined here? Does this acreage include all <br /> surfaces to be reclaimed on the pit floor and the F2 and F3 backfill areas for mining phase <br /> III? <br /> Response: The areas in Table L-1 include all areas disturbed through mining Phase III. <br /> This includes the areas for fines stockpiles F1, F2, and F3 and the pit floor. The pit floor <br /> and stockpile tops features are combined as they are both flat surfaces and the planned <br /> reclamation activities are the same. The acreage includes the pit floor area (minus the plant <br /> area) and the area associated with F2 and F3. <br /> 84) On page L-4, Table L-1, please explain what type of disturbance is included in the category <br /> of Mining Related Area, which totals 32.64 acres. <br /> Hitch Rack Ranch Quarry(M-2017-049) <br /> Response to Comments—March 9,2018 <br />
