MAXWELL TRINE <br /> File No. C-013081 <br /> Response to Draft Findings Document <br /> VI . hydrologic Pala.nce : Ground Water - Rules 2 .04 .5 , <br /> 2 .04 .7 , 2 .0 74 , 2_05_6 3 and 4 .05 <br /> Stipulation (Springs Pr Seeps) <br /> In conformance with Rule 2 .04 .7 ( 2) (a.) and (4) (d ) , CFpr.I <br /> herewith submits copies of unpublished UrG" compil.a.tion of: <br /> intermittent flow that originates as springs and seeps from <br /> bedrock n,nd abandoned mines feeding draina.ge.s north of the <br /> Purgatoire River and corresponding quality data.. Inventory and <br /> data were collected during thesummer of 1981 nee data packet <br /> (VI Iiydro_logic Ba.la.nce ) . <br /> CF&I offers this data collected over a much greater area <br /> than that covered by its permit application to assist the Tlined <br /> Land Reclamation Division with its finding that springs n.nd seeps <br /> regionally represent nn inconsequential contribution of <br /> groundwater to the surface water resources tra.versi_ng the area <br /> dedicated to mining. Further, the data supports CFP,I ' s findings <br /> from its investigation that the Raton form,a.tion sediments <br /> encountered in mining are low yield with respect to hydraulic <br /> conductivity . Consequently, the risk of material- damag- to the <br /> hydrologic bala.nce both within ,.nd without the permit arr)a. is <br /> severely restricted . <br /> Of the data, submitted , only that, collected in Sa.nti_stevan <br /> a.nd Wet Canyons are relative in the site specific senso . While <br /> spring discharges measured in Santistevan Canyon a.re reflected to <br /> be low ,yield , those measured in Wet Canyon a.re ref1pctn� to <br /> produce the highest yields of the entire survey. Yet , the <br /> corresponding quality measurements demonstrate the watr-r of those <br /> springs composed dominn.ntl_y of meteoric origin and an intimate <br /> part of the surface water regime . In light of th- quality data, <br /> bedrock contribution to the surface water flow of 'Jet Canyon can <br /> be regarded as negligible. Further , the data, demonstrates the <br /> interrupted cha.ra.cter of the stream during 1981 , an n,bnormal.ly <br /> high precipitation year. <br /> The USGS regional data, thus submitted should be sufficient <br /> for the division to conclude CF1-I ' s mining activities will have <br /> little, if any, effect on the minor contribution of springs and <br /> seeps to the State ' s water resources . <br /> a <br />
