1. Railway Containment Area: Technical Revision No.15 <br />provided the necessary SAE demonstrations. The <br />area was fitted with a silt fence for sediment <br />drainage to the west with the approval of TR 17, <br />approved 12/1/93. <br />2. Southwest Sediment Trap: Located on the eastern <br />side of the loadout, the trap has been fitted with <br />a silt fence for sediment drainage with the <br />approval of TR 17. <br />3. Former truck-turn-around: Located on the eastern <br />side of the loadout, this area has also been fitted <br />with a silt fence for sediment control through TR <br />17 approval. <br />EFCI has submitted all hydrologic calculations and SEDCAD <br />predictions for the SAE's permitted both at the mine and <br />loadout sites which can be found in Exhibit 19, Appendix C of <br />the permit application. <br />All the remaining surface disturbed areas drain directly or <br />are routed indirectly through one of the three sediment ponds <br />on the mine site, or two at the loadout. Sediment ponds 1, 4 <br />and 5 are used for sediment settling at the mine site, while <br />sediment ponds L-1 and L-2 are used for sediment settling at <br />the loadout. <br />Sediment ponds 2 and 3 are part of a water recycling system <br />that are used primarily for storage of water pumped from the <br />Corley Well and used in the mine processing facility. <br />S. Stream Channel Diversions <br />1. The Division has approved the permanent diversion of <br />Magpie Creek, an ephemeral channel draining at least one <br />square mile. This decision is based on a finding that <br />the proposed diversion meets the requirements of Rule <br />4.05.18 and 4.05.4, applicable local, State, and Federal <br />statutes and regulations and that the diversion is <br />designed to safeguard public safety and to minimize <br />adverse impacts to the hydrologic balance. (4.05.4(1) and <br />(4))• <br />2. Therefore, the Division proposes to approve a permanent <br />diversion. This diversion is consistent with applicable <br />state law, will not diminish downstream water rights and <br />meets the requirements of Rule 4.05.4. (4.04.4(4)). <br />With the approval of Technical Revision No. 15 as part of <br />the Mid-term Review on 12/1/93, EFCI was granted approval <br />for the permanent diversion after the submitted <br />engineering plans and hydrologic calculations were <br />reviewed by the Division. With the submittal of plans <br />and their subsequent approval, Stipulation No. 17 was <br />28 <br />
