Mr. Ben Langenfeld, P.E. <br />Page 3 of 5 <br />16 March 2021 <br />already been affected. Given this reporting, 50 acres does not cover the current level <br />of disturbance or the proposed new area to be affected. <br />Please clam as per above and as per question 6 as follows. <br />6. Please peruse the 1980 reclamation plan on file at DRMS and for additional <br />compliance requirements of Rule 3.1, updating the narrative with appropriate <br />information addressing both Rule 6.4.5 and Rule 3.1 as they pertain to the activities <br />associated with TR4 specifically addressing: <br />o timing associated with TR4 <br />o mining processes <br />o reclamation measures <br />o permanent features that may be a requested after mining the area associated <br />with TR4 has been completed <br />o reclamation cost estimate as per Rule 6.4.12, Exhibit L. <br />DRMS Response 2021 March <br />Table E-2 indicates the permit area is 236 acres. The approved permit area is 133 acres, <br />please clarify this discrepancy. <br />6a Please submit a revised page as appropriate. <br />6b. How many cottonwoods will be replanted per acre? Please revise the reclamation <br />plan narrative with this information. <br />6c. Cost Estimate, Exhibit L states 36 acres are affected as of January 2021, this does not <br />appear to be accurate given the last annual report submitted to the Division, please <br />clarify. <br />6d. The applicant is requesting to bond for a maximum disturbance of 40 acres. This is in <br />conflict with the proposed maximum disturbance of50 acres and does not appear to <br />account for all the current affected land at the site. Please update this reclamation cost <br />estimate to be reflective of onsite conditions and the proposed expansion of Pond 5. <br />6e. Given the uncertain nature ofappropriations ofwater for the basin with the Division <br />of Water Resources, the Division must hold a bond protective of current and future water <br />rights. Please provide a cost estimate to backfill the proposed expansion of Pond 5 to <br />cover the exposed groundwater with two feet offill. <br />Rule 6.4.7 Exhibit G Water Information <br />DRMS notes that the Yampa River is highly responsive to seasonal precipitation and snow <br />melt. High water, prevalent during spring snow melt is often maintained into late spring or <br />early summer followed by rapid drawdown. Under these hydrologic circumstances bank <br />stability and flood mitigation protecting neighboring properties as well as water quality are <br />essential components of DRMS's design review. <br />7. Please provide a narrative addressing sections(]) and (2) of the above mentioned rule. <br />Resolved <br />DRMS Response 2021 March <br />TR4 Bunn Ranch Pit March 2021 <br />ADQ #2 <br />
