Because the Applicant's <br />Discharge Pemrit and monitoring program apply to all offsite surface dischazges, this <br />would also include dischazges into North Cleaz Creek. Additional measures to control <br />dischazges, including radioactive disehazges, are described below in paaagraph 23. <br />22. The weight of the evidence demonsh~ates that the Applicant has met the minimum <br />requirements of Rule 6.4.7(2)(c). <br />23. Issue 7(k'), Adequate Assessment ofDLsturbances to Prevailing Hydroioglc Balance, <br />(Rule 3.I.~. As stated in the Division's Rationale, the Applicant has provided a detailed <br />assessment of potential impacts to both surface and groundwater in the affected land and <br />surrounding area. This assessment includes a hydrologic analysis prepared by Lyman <br />FIenn, Inc. ("Henn Groundwater Report"}, which indicates that although groundwater <br />will probably be exposed during excavation, groundwater is not anticipated in <br />appreciable accumulations and it should not be necessary to discharge or pump <br />goundwater from the quarry. The proposed operation is not expected to have negative <br />off-site impacts on groundwater. The Henn Groundwater Report concludes that adverse <br />water quality impacts will not be expected at nearby offsite goundwater wells. Atypical <br />quarry blast is not expected to disrupt the general pattern of groundwater hydrology. <br />Hypothetical "plugging" of groundwater pathways along interconnected fractures is <br />unlikely to be extensive or to seriously impact transmissivity, and it is unltlcEly that such <br />an effect would extend the radius of influence of groundwater drawdown to a point where <br />neazby wells would be effected. The Henn Groundwater Repor[ also concludes that <br />although there will be a localized effect on groundwater supply, the effect is not likely to <br />extend faz enough to physically affect offsite wells in the surrounding area.
