2. The applicant will conduct monitoring of surface water in a manner approved by <br />the Division. The monitoring plan was submitted under 2.05.6(3)(3)(b)(iv) and <br />can be found in Section ILC.2.e of permit application, Vol. I (4.05.13(2)). <br />Currently, surface water monitoring is currently limited to monitoring required <br />under the CDPS discharge permit, as necessary to demonstrate compliance with <br />water quality standards and effluent limitations pursuant to 4.05.2. Additional <br />surface water monitoring which had previously been required was terminated in <br />1997, pursuant to TR -47. <br />The Division has reviewed the surface and ground water monitoring plans as part of <br />the renewal process. These monitoring plans are adequate to monitor for development <br />of impacts, if any should develop. The 2008 Annual Hydrology Report stipulated that <br />the point of compliance for 2007 -2008 was monitoring well 294M. In subsequent <br />years, the point of compliance became monitoring well 22 -3M. <br />E. 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 and <br />quantity will not be adversely affected as a result of the disturbance, and <br />appropriate riparian vegetation will be reestablished upon final reclamation. The <br />buffer zone variance is granted for the raw water lagoon and dike along the <br />White River, at the mouth of Scullion Gulch. A riparian revegetation plan is <br />provided in Section V. 1.4.h of the permit application (4.05.18(1)). <br />F. Probable Hydrologic Consequences <br />The probable hydrologic consequences of mining within the Deserado Permit Area <br />are addressed within Section II.C.5 of the permit application. The permittee's <br />statement of hydrologic effects has been reviewed by the Division for compliance <br />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 -term <br />impacts which will occur as a result of surface facilities appurtenant to the under- <br />ground mine include reduction of water yield from the mine area to the White <br />River, increased sediment loads from disturbed areas, and water quality <br />degradation from the refuse disposal area and mine water discharge. Long -term <br />impacts will center on the effects of subsidence under Scullion Gulch and Red <br />Wash. See the subsidence section of this document for further discussion of <br />subsidence impacts. <br />Small, short -term surface water losses will occur as a result of two factors: <br />
