Stipulation No. 3 required Eastside to provide a plan for locating the <br /> 60-percent sediment level in both sediment ponds. The plans are shown on <br /> Drawing 3 (SP-1 ) and Drawing 4 (SP-2) . This stipulation also requires <br /> maintenance of sediment accumulation below this level , which has been <br /> performed by the operator. Therefore, Stipulation 3 is modified, and remains <br /> in effect. <br /> Stipulation No. 3 <br /> SEDIMENT PONDS SP-1 AND SP-2 WILL BE MAINTAINED WITH SEDIMENT AT OR <br /> BELOW THE 60 PERCENT LEVEL. <br /> The Division's review of Annual Hydrologic Reports submitted by the operator <br /> indicates little or no surface water impact occurring. <br /> With acceptance of the above stipulations, the operation is in compliance with <br /> the requirements of this section. <br /> VI. Ground Water Hydrology - Rules 2.04.5, 2.04.7, 2.05.3(4) , 2.05.6(3) and <br /> 4.05 <br /> The Eastside Mine ground water monitoring program was modified by Technical <br /> Revision 3, approved in April , 1988. The mine wells 0.5 and 1 .5 (Stipulation <br /> No. 1 in previous section) are no longer sampled, as it had become clear that <br /> no off-site impacts were occurring. The permittee continues to conduct a <br /> yearly mine inflow study, and to monitor mine water discharge in accordance <br /> with Stipulation No. 1 . <br /> The refuse disposal area referred to in Stipulation No. 1 has not been <br /> constructed at the time of permit renewal . <br /> The operation is in compliance with the requirements of this section. <br /> VII. Water Rights and Replacement - Rules 2.04.7(3) and 4.05.15 <br /> Stipulation No. 4 of the Eastside permit required- that the operator quantify <br /> consumptive use of water at the mine, and that possible sources of <br /> augmentation water be identified. At maximum production, Eastside estimates <br /> that approximately 4 acre-feet of water would be consumed annually. Eastside <br /> has purchased one share of-the-Farmers Irrigation Ditch Company, which <br /> entitles them to 3.6 acre-feet of 'water _per ,year, to augment flow from Grass <br /> Valley Reservoir. Stipulation No. 4 is therefore satisfied. <br /> The operation is in compliance with the requirements of this section. <br /> VIII. Probable Hydrolooic Consequences-of Mining at the Eastside Mine <br /> The Probable Hydrologic Consequences section of the original Eastside Mine <br /> Findings Document described in detail the hydrologic and geologic environment <br /> at the mine, and is hereby incorporated into this document. Due to the <br /> extensive periods of inactivity, very little mine development has taken place <br /> at Eastside. For the same reason, there has been little or no hydrologic <br /> impact during the first permit term. <br /> -7- <br />
