r <br /> �•'� C) <br /> Transit Mix Concrete Co. RPM,Inc. <br /> (2) (a) If the operations is expected to directly affect surface or <br /> ground water systems, ... <br /> This provision is not applicable. <br /> (b) Identify all known aquifers: <br /> From the 1992 Amendment, Mine Plan: <br /> "The sand is 90 to 100 feet thick and rests, usually, on top of about 10 to 20 feet of coarse gravel. <br /> The gravel rests on top of shale. In some places the gravel seems to be missing and is replaced <br /> by sand which rests on top of shale. The pattern of this variation has never been determined with <br /> accuracy, but is indicated by ground water patterns...The definition of this pattern would <br /> probably be academically interesting, but is of little practical value, as mining will not intercept <br /> the ground water." (In other sections of this revision we discuss how the construction of the <br /> waste disposal pond will prevent interception of ground water.) <br /> "Generally, the gravel acts as an aquifer. Where gravel occurs water is found. Where gravel is <br /> not found, the water is usually absent or is in small quantity." <br /> (The rest of Section 6.4.7 is not applicable) <br /> 6.4.12 Reclamation Costs: <br /> There is no proposed change in the reclamation cost. Once the embankment is constructed, it <br /> will be seeded. The embankment is to be part of the reclamation plan and post mining land use. <br /> The fines disposal impoundment is not actually a part of the on-going mining operation. It will <br /> be dedicated to the construction materials processing facility which is not part of the mining <br /> operation. (It receives material for process from a number of CMC/TMCC mining operations.) <br /> In addition, as the pond fills with fines, the slopes needing backfilling or regrading will decrease. <br /> 6.4.13 Other Permits and Licenses; <br /> To the best of our knowledge, no other permits or licenses are required to construct and operate <br /> the proposed wash fines disposal pond. This is an on-going mining operation and all necessary <br /> permits and licenses are in place. The Division of Water Resources has stated the embankment <br /> structure is non-jurisdictional, please see Exhibit 2. <br /> 6.5 Geotechnical Stability: <br /> 11 <br />
