DRMS Response:The revised map must be certified by a qualified registered professional engineer <br /> or professional geologist,with assistance from experts in related fields such as land surveying and <br /> landscape architecture in accordance with Rule 2.10.3(2). Please revise the maps accordingly to <br /> include this certification. <br /> 18. Current page 2.04-11c states core holes were drilled in 2020 and 2010 however it does not indicate where in <br /> the permit the drill logs for these holes are located. Please revise this section of the permit to indicate where <br /> these drill logs can be found in the permit and please provide this information as an exhibit to the permit in <br /> accordance with Rule 2.04.6(3)(a)(iii)(A). <br /> a. NECC Response: The 2010 drilling logs are found Exhibit 4 1(confidential)of the PAP.Once the <br /> information for the 2021 drilling has been completed and complied,NECC will send in a revision <br /> adding the drill logs to Exhibit 41. <br /> b. DRMS Response:Please revise page 2.04-11e to indicate the drill logs are located in confidential <br /> Exhibit 41. <br /> Rule 2.04.7—Hvdrolo2v Description <br /> 20. The legend of Map 8 does not appear to be reflective of the various lines and symbols used on the map. For <br /> example the revised PR5 permit boundary appears to be a thick green line not an orange-yellow dashed line <br /> as the legend indicates. Also there is a red dashed line that appears to delineate the pre-PR5 boundary. <br /> Please revise the map so it features are accurately portrayed in the legend. <br /> a. NECC Response: The legend and information of Map 8 have been to be consistent with each <br /> other. <br /> b. DRMS Response:The revised map must be certified by a qualified registered professional engineer <br /> or professional geologist,with assistance from experts in related fields such as land surveying and <br /> landscape architecture in accordance with Rule 2.10.3(2). Please revise the maps accordingly to <br /> include this certification. <br /> c. DRMS Response: Map 8 depicts many features and items referenced throughout the Permit <br /> Application package. Many of the features and labels overlap and it is difficult to find the location of <br /> specific features such as the approved surface and groundwater monitoring points. DRMS <br /> recommends NECC submit several series of Map 8 so critical features can be easily identified. <br /> 21. Please update Section 2.04.7,Map 8,and Map 20 to depict and provide updated information required by Rule <br /> 2.04.7(1)(a)(iv)and(4)(a). <br /> a. NECC Response: Section 2.04.7 and Maps 8 and 20 have been updated to include the required <br /> information. <br /> b. DRMS Response: Please update the following with current information: <br /> i. Table 10 with a current groundwater user inventory. <br /> ii. Map 8 accordingly based on a current survey of groundwater resources. <br /> 22. Currently page 2.04-19 indicates dewatering of the Allen and Apache coal seams for mining is not expected <br /> to lower water levels in alluvial wells but may impact bedrock wells. Is dewatering necessary for mining in <br /> the Blue Seam? If so,what impact will it have on alluvial wells?What impact will it have on the bedrock <br /> wells? Please revise page 2.04-19 to include this information. <br /> a. NECC Response: Page 2.04-19 has been revised. <br />
