<br />4.0 PLAN FOR AUG!ffiNR'ATSON <br />PCC is required by the State to conduct its mining <br />operations so as to not cause impact to any existing water <br />rights, and to Rave rights for all water that it <br />consumptiv¢ly uses. Five ponds were constructed and era <br />currently in operation in the vicinity of the NUCi.A mining <br />area. A sixth pond (Pond 007) will be constructed and <br />operated in conjunction with the NUCLA BAST mining area. <br />Water from the ponds will provide the water supply for dust <br />suppression and construction compaction make-up water. Pond <br />operation may result in out-of-priority storage and use of <br />this water. <br />• ~ The NUCLA EAST pit will be excavated in accordance with <br />PCC•s mine plan as described in the permit application. The <br />pit excavation will extend below the water table in the <br />overburden aquifer. Pit inflows will cause a drawdown of the <br />adjacent shallow water table which may impact surface-water <br />rights that depend on the shallow overburden aquifer for <br />their supply. <br />Section 4.1 presents an overview of the augmentation <br />plan to mitigate potential impacts to water rights affected <br />by the above facilities and mining operations. Section 4.2 <br />provides additional details about the augmentation water <br />Sa <br /> <br />GEO7RAN5. INC. <br />REVISED MARCN 2006 Attachment 2.05.6(3)(b)(v)-1-23 <br />
