The A.?R was received <br />on January ??, 2009 and contains water quantity and ?ualrty data for the 20??-2005 water year. <br />One report is submitted for both mines since they are in close proximity and the surface water <br />and groundwater monitoring programs are essentially combined for the two sites. <br />The frequency of data collection far surface and groundwater is in compliance with the appra?red <br />monitoring plan contained ?n the permit document. with exception of a few surface water <br />samples, all required monitoring data were collected and reported. During the 4`? quarter X007 <br />water quality samples were not obtained from surface water sites w-1 and -S due to low <br />flow conditions and water quality samples were not tal?en at sites -2 and Sw-5 due to dry <br />conditions In Mclane creek. <br />There was no discharge from the Munger sediment pond throughout the water year and only one <br />discharge from the Mc?lane sediment pond ?n February 200$. Mine inflow water was <br />discharged from the mine during the water year. Outfall ?02A at Mclane Mine provides for <br />discharge from the underground mine to East Snit Creel. According to the report mine water <br />was discharged to East salt Creep in February, March, May and June of 2005 totaling <br />approximately 1.1 rriilllon gallons with the rennainder ofmine inflow water being consumed in <br />the mine or used outside to water roads, Although there 1s also a permitted CDPS mine <br />discharge outfall at Munger banyan, there i no mine discharge to the surface from the Munger <br />Mine site. All discharge n]on?tor?ng and reporting is done 1n accordance with e ?? Permits <br />for each site. <br />The Probable ?ydrolagic Consequences ?PI?C} discussion in the permit document and the <br />Division's previous findings indicate that mine discharge will have a small impact on East Salt <br />Creek. The AHR states that the rn?nes well have no s1gn?ficant effect on the quantity and qua??ty <br />Office of 0{f ice oi: <br />Mined Land Reclamation Denver # Grand function ?
