<br /> <br /> <br />Per Rule 2.04.6(3)(a)(iii), please acquire geochemical <br />information of the roof and floor. Per Table 3.B.2.b. of the <br />Division's Guidelines for the Collection of Baseline Water <br />Oualitv and Overburden Geochemistry Data, please obtain composite <br />samples from the first ten feet of strata overlying the coal seam <br />and the first five feet underlying the coal seam, and have them <br />analyzed for the following parameters: <br />pH <br />Electrical Conductivity <br />Total Combustible Solids <br />Lithologic Classification <br />Textural Analysis <br />% Sand <br />Silt <br />% Clay <br />Saturation Percentage <br />Sodium Adsorption Ratio <br />Calcium <br />Magnesium <br />Nitrate-Nitrite <br />Sodium <br />Sulfur <br />% pyritic sulfur <br />sulfate sulfur <br />% organic sulfur <br />Total Sulfur <br />Arsenic <br />Boron <br />Cadmium <br />Copper <br />Iron <br />Lead <br />Manganese <br />Mercury <br />Molybdenum <br />Selenium <br />Zinc <br />4. To characterize the physical properties of the aquifers at the <br />site per Rules 2.04.6(3)(a)(iii)(A) and 2.04.7(1)(b), please <br />perform aquifer pump tests on the Cliffhouse Sandstone, the <br />Menefee Formation and the Point Lookout Sandstone, to ascertain <br />the transmissivity, storativity, porosity, and both horizontal <br />and vertical permeability for each of these strata. <br />5. Per Rule 2.04.6(3)(a)(iii)(A), please provide lithologic logs for <br />all drill holes, including the location of subsurface water if <br />encountered, to supplement existing geological baseline data and <br />provide a framework for evaluating the geochemical data and water <br />monitoring data which is collected. <br />Per Rule 2.04.6 (3)(a)(iii)(A), additionally provide geophysical <br />logging of each hole for gamma, resistivity and density <br />measurements. <br />Per Rule 2.04.7(1)(a), please complete the drill holes to <br />establish one monitoring well in the Point Lookout Sandstone and <br />one in the Menefee Formation. We recommend additionally <br />submitting a set of generic completion diagrams to the Division <br />in advance of installation, to ensure agreement on the proper <br />method of establishing a monitoring well in the zone of interest. <br />
