of surface drainage with a discharge from underground workings will occur (4.05.2(3)(b)(ii)). <br /> The small areas to be exempted are located as follows: <br /> • SAE at slurry well site and other small areas on the west side of the permit area <br /> • Two SAEs for East Portal Water Tanks <br /> • SAE south of Pond 007A <br /> • SAE east of the Development Coal Waste Pile <br /> • SAE north of the river and west of the RDA belt(including Topsoil Stockpile 42) <br /> • Two SAEs east of the RDA <br /> • SAE approximately 1,500 feet east of Pond 08. <br /> Stream Channel Diversions <br /> During a previous permit term the operator submitted design details for permanent diversion of <br /> the Middle Fork of the Purgatoire River. This diversion was necessary to accommodate coal <br /> storage and preparation plant operations. The Division approved this permanent diversion and <br /> the operator completed the approximately 580-foot diversion in the spring and early summer of <br /> 1985. This decision is based on a finding that the proposed diversion meets the requirements of <br /> 4.05.18 and 4.05.4; applicable local, State, and Federal statutes and regulations; and that the <br /> diversion is designed to safeguard public safety and to minimize adverse impacts to the <br /> hydrologic balance (4.05.4(1) and (4)). The Division has found that this diversion will not <br /> diminish downstream water rights and meets the requirements of Rule 4.05.4(3). Exhibit 21 of <br /> the PAP (Supporting Information for Permanent Diversion) contains the pertinent design <br /> information. <br /> Channel linings, sediment ponds, and channel roughness structures are proposed for use to <br /> control erosion. These means are proposed to be approved by the Division since they are <br /> necessary to control erosion, they are stable, and will require infrequent maintenance <br /> (4.05.4(2)(a)). <br /> Sedimentation Ponds <br /> With TR-68 (issued February 2015),the Division approved the retention of Ponds 004A and 08. <br /> Surface and Ground Water Monitoring <br /> The applicant will conduct monitoring of water in a manner approved by the Division. The <br /> groundwater monitoring plan and surface water monitoring plan are described in Section 2.05 of <br /> the PAP. This section includes monitoring frequency in Table 27 and a water quality parameter <br /> list in Table 28 (4.05.13(1)). <br /> Transfer of Wells <br /> No exploration wells have been transferred to monitoring well status since RN-06. <br /> New Elk Mine <br /> November 2019 Findings for RN-07 <br /> 13 <br />
