Tne baseline monitoring presently <br />conducted by the company can De reduced and still provide adequate <br />baseline data for permitting. The reductions are justifiable given the <br />proposed mine plan and the results of monitoring supplied to the Division. <br />I. t+lonitoring in the Alkalai Creek Drainage Basin <br />Previously, strip mine pits and surface facilities were planned in the <br />Alkalai Creek Drainage. Presently no strip mining is planned in Alkalai <br />Creek Drainage, antl all surface facilities are planned to oe placed on <br />upper terraces of the Colorado River and a small-ephemeral drainage to <br />the Colorado River. Permit baseline monitoring may De reduced on Nlkalai <br />Creek to the following: <br />a. Monitoring the downstream surface water flow and quality station <br />any Alkalai Creek (ALK-2) and eliminating the upstream station <br />(ALK-1) from monitoring. <br />b. Monitoring surface waters at the downstream station (ALK-2) monthly <br />for field parameters and quarterly for the reduced water chemistry <br />list. <br />c. Monitoring of Alkalai Greek alluvial gr <br />to only monitoring the downstream well <br />. water quality list. <br />d. All alluvial and talus monitoring wells <br />should be monitored monthly for ground <br />electro-conductivity, and temperature. <br />e. The bedrock well in Alkalai Creek basin <br />monthly for water levels and biannually <br />quality list. <br />ound quality may be reduced <br />quarterly for the reduced <br />(UW-2, OW-3 and OlJ-4) <br />water levels, pH, <br />(SK-2) should be monitored <br />for the reduced water <br /> <br />423 Cen!ennial Building, t313 Sherman Street Denver, Colorado 80203 Tel.
