<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />1 <br /> <br /> <br />1 <br />1 <br /> <br /> <br />1 <br />Surface water monitoring consists of flow measurement and sampling of <br />selected surface stations, discharge points and sample sites on a weekly <br />basis from March through June, and on a monthly basis thereafter, until <br />flow ceases. Selected surface stations are equipped with water level re- <br />corders or crest staff gauges for continuous monitoring of flow. Discharge <br />points are also equipped with flow measuring devices. Sample sites are <br />shown in the attached table, 1985 Surface W;:ter Monitoring. At the time of <br />surface water sampling, temperature, pH, electrical conductivity and dis- <br />solved oxygen are measured, along with a v:~ual check for oil and grease. <br />The parameters analyzed for selected surface stations (SSS), discharge <br />points (SDP) and sample sites (SS) are sho!•~n in the attached table, 1985 <br />Surface Water Quality Analyses. <br />LIFE-OF-MINE MONITORING PLAN <br />As required by Colorado Rule 4.05.13, CYCC has coiamitted to the moni- <br />toring and reporting of certain data over the life of the mining and recla- <br />mation operations. Copies of the Discharge Monitoring Report (DMR) pre- <br />pared for the NPDES Permit are to be forwarded to the Colorado Department <br />of Health - Water Quality Control Division and the Colorado Mined Land Rec- <br />lamation Division on a quarterly basis. Data from the monitor sites shown <br />on the attached map are to be forwarded to the CMLRD on an annual basis. <br />The monitor sites listed below are included in the Annual Hydrologic <br />Monitoring Report. <br />Life-Of-Mine Monitoring Sites <br />Bedrock Wells Spoil Wells** <br />y~y~-:40c8 026-BRDH1[,..~. oB 026-SP-1 <br />y/a~-l8',PaB 026-79-4 W-c °6 026-SP-2 <br />~F~_~~p,ga 026-79-6 w't °y 026-SP-3 <br />9/fr-i~coa 026-79-7 w-a r, <br />~~~y~_~oaa 009-79-4 woa <br />Alluvial Wells Selected Surface Stations <br />001-5-5 8* / / <br />001-5-6 12 / ~ <br />006-AW-1 16 <br />006-AW-2 26 <br />009-5-10 33 / / <br /> 39 <br />' *Transferred to Twentymile Coal Company (TGC). <br />**Installed in the Fall 1984, sampling to begin 1935. <br /> <br />1 <br />
