Rule 2: Permits Alluvial Wells Alluvial wells designated for monitoring are listed in Table 2.05.6-14. TABLE 2.05.6-9 LORENCITO CANYON MINE ALLUVIAL WELL MONITORING SITES Site Reason for Monitorin Status MWJC-1 Surface Mine Active MWLC-1 Surface Mine Active MWLC-2 Surface Mine Active MWPC-1 Surface Mine Terminated MWLO-E Loadout AVF Active MWLO-W Loadout AVF Terminated These alluvial wells will be monitored on asemi-annual basis in the second and fourth quarters for field parameters and annually in the fourth quarter for analytical and calculated values during final reclamation. Site MWL0.W has been terminated. The surface owner constructed a gravel quarry west of the loadout location that resulted in the abandonment and excavation of this well site. Monitoring of site MWPC-1 has been terminated as the mine is now in final reclamation and mining related impacts never occurred within the area of influence affecting site MWPC-l. The Miae loadout area is • designated as a post mining industrial land use area. Upon achieving bond release for the loadout, monitoring of MWLO-E will be terminated. These sites will require monitoring for parameters as determined from the initial baseline sampling. To determine these parameter the ~n_da.rtc were compared to the values reported during the baseline period and those values which exceeded standards or were within 80.0 of the lowest standards value were selected. The list of parameters in Table 2.05.6-15 is deemed adequate to monitor springs and seeps. The parameters silver, cyanide, copper, mercury, and nitrate as N (dissolved) were not included in this list since either the standards are less than the diction limit or no analyses of these constituenLc were above the detection limits. Likewise lead (dissolved), selenium (dissolved), and zinc (dissolved) have been removed from the lisle • 2.05-108 (Revised 4/17/07)
