humidity cell tests. How many of the tests involved interaction of acidic waste rock leachate with <br />geologic materials outside of the diatreme? <br />VI. T.: Flow rate will be irrelevant only if the uniform batch reactor concept proposed by the <br />Operator turns out to be correct, a concept that will only be validated through long-term post- <br />closure monitoring. <br />VI. U.: Assertions that mining will not and cannot increase the concentrations of constituents are <br />speculation that will only be proven via long-term monitoring. Exhumation of, and exposure of, <br />sulfide minerals to atmospheric conditions by mining activity invariably enhance and accelerate <br />oxidation of sulfide minerals. <br />VI. V.: Whether the oxidation and neutralization behave as predicted will have to be validated by <br />long-term monitoring. The comment on the movement of air is again speculation, and the true <br />response of the system to the mining and waste rock placement, assuming estimates of travel times <br />are accurate, will be proven through long-term monitoring. <br />REFERENCE <br />Eary, L.E., Runnells, D.D., and Esposito, K.J., 2003, Geochemical controls on ground water <br />composition at the Cripple Creek Mining District, Cripple Creek, Colorado; Applied Geochemistry, <br />18, p. 1-24.
