TABLE 1 <br /> Martin Marietta Materials <br /> Duckworth Mine <br /> Packer Permeability Test Results by Olson Associates <br /> Interval Applied Calculated <br /> Date Boring Tested Lithology Pressure Permeability <br /> (feet) Range (cm/s) <br /> (psi) <br /> 9-11-2002 DW02-MW01 C 26.5—29.9 Siltstone 4—13 No Take <br /> 9-13-2002 DW02-MW03C 1 32.9—34.9 Siltstone 5—16 No Take <br /> Notes: <br /> 1. Packer permeability tests were performed in NX core intervals using a single packer inflated to <br /> 250 psi. <br /> 2. Packer permeability tests were run over the range of pressures outlined above as measured with <br /> a pressure gauge. Flow into the formation was measured with an in-line flow meter. <br /> 3. Packer tests were performed by Olson Associates. <br /> P.\24097\133-24097-14003\Docs\Reports\Design Memorandum\Table l.docx <br />
