B. Stream Channel Diversions <br />The Division has approved the diversion of an ephemeral stream <br />draining at least one square mile. This decision is based on a finding <br />that the proposed diversion of a portion of Ciruela Canyon meets the <br />requirements of 4.05.18 and 4.05.4, applicable local, State, and <br />Federal statutes and regulations and that the diversion is designed to <br />safeguard public safety and to minimize adverse impacts to the <br />hydrologic balance (4.05.4{1) and {4)). <br />2. Channel lining structures, retention basins, and artificial channel <br />roughness structures are proposed for use to control erosion. The <br />Division approves these means since they are necessary to control <br />erosion, they are stable and will require infrequent maintenance <br />(4.05.4(2)(a)). <br />3. The Division has approved a permanent diversion of a portion of lower <br />Ciruela Canyon near the toe of the development waste pile. This <br />diversion is consistent with applicable state law, will not diminish <br />downstream water rights and meets the requirements of Rule 4.05.4 <br />(4.05.4(3)). <br />C. Surface and Ground Water Monitoring <br />The applicant will conduct monitoring of ground water in a manner <br />approved by the Division. The ground water monitoring plan is <br />presented in the permit application on pages 2.05-47b to 2.05-47f <br />(4.05.13(1)): <br />2. The applicant will conduct monitoring of surface water in a manner <br />approved by the Division. The surface water monitoring plan was <br />submitted under 2.05.6(3)(b)(iv) and is shown on pages 2.05-47b to <br />2.05-47f of the permit application (4.05.13(2)): <br />D. Probable Hydrologic Consequences <br />The probable hydrologic consequences concerning ground water of the <br />Golden Eagle mine were detailed for active mining operations and post- <br />mining conditions. Due to the Golden Eagle Mine now being in a reclaimed <br />condition, the ground water probable hydrologic consequences are detailed <br />for the post-mining condition only and are as follows: <br />^ Reduction of ground water discharge to streams <br />^ Reduction of overburden spring flow <br />^ Ion changes in the ground water system <br />14 <br />
