1. The applicant will conduct monitoring of ground water in a manner approved <br />by the Division. The ground water monitoring plan can be found in Section <br />ILC.3.h, Vol. I of the permit application (4.05.13(1)). <br />2. The applicant will conduct monitoring of surface water in a manner approved <br />by the Division. The monitoring plan was submitted under 2.05.6(3)(b)(iv) <br />and can be found in Section ILC.2.e of the permit application, Vol. I <br />(4.05.13(2)). Currently, surface water monitoring is limited to monitoring <br />required under the CDPS discharge permit, as necessary to demonstrate <br />compliance with water quality standards and effluent limitations pursuant to <br />4.05.2. Additional surface water monitoring, which had previously been <br />required, was terminated in 1997 pursuant to TR -47. <br />The Division reviewed the surface and ground water monitoring plans as part of <br />the Permit Renewal 05 process. These monitoring plans were determined to be <br />adequate to monitor for the development of impacts, if any should develop. The <br />2010 Annual Hydrology Report stipulated that the point of compliance will be <br />monitoring well 22 -3M. <br />F. Stream Buffer Zones <br />The Division approved underground mining activities within 100 feet of a <br />perennial stream with a biological community. This decision was based on a <br />finding that the original stream channel will not be affected, water quality <br />and quantity will not be adversely affected as a result of the disturbance, and <br />appropriate riparian vegetation will be reestablished upon final reclamation. <br />The buffer zone variance is granted for the raw water lagoon and dike along <br />the White River, at the mouth of Scullion Gulch. A riparian revegetation <br />plan is provided in Section V. 1.4h of Volume IV of the permit application <br />(4.05.18(1)). <br />G. Probable Hydrologic Consequences <br />The probable hydrologic consequences of mining within the Deserado Permit <br />Area are addressed within Section ILC.5 of Volume I of the permit application. <br />The permittee's statement of hydrologic effects has been reviewed by the Division <br />for compliance with Rule 4.05.1 and 2.05.6(3). <br />Surface Water Impacts <br />Impacts to the hydrologic balance will occur as a result of the mine. Short- <br />term impacts which will occur as a result of surface facilities appurtenant to <br />the underground mine include reduction of water yield from the mine area to <br />the White River, increased sediment loads from disturbed areas, and water <br />quality degradation from the refuse disposal area and mine water discharge. <br />31 <br />
