1 <br />' monitored only if there is discharge from the sediment pond (RP-1) located below the refuse <br />disposal area. To date, September 30, 1990, that has not occurred. Crest gage and sample <br />' station SW24-1 along Red Wash above the mine was washed out by a flash flood in fhe Spring <br />of 1983. Grab samples were collected at SW24-1 until July 1986 when a new single stage <br />t sampler was installed. The stock water ponds at SW6-1 and SW33-1 are usually dry. Crest <br />gage and sample collection stations SWi-1, SW11-1, and SW31-1 are monitored quarterly; <br />however, run off events often contain such high quantities of suspended solids that sampler tubes <br />' are plugged and the gaging device silted in. Constant servicing of these stations is necessary <br />with no guarantee that the next run off event will be measured and a sample collected. Kenney <br />' Reservoir has inundated the White River alluvium below Scullion Gulch and grab sample stations <br />SW11-2 and SW12-1. <br />' Following review of the Second Annual Deserado Mine Hydrology Report, Colorado Mine Land <br />Reclamation Division (CMLRD) suggested that surface water monitoring sites SW12-1 and <br />' SW11-2 be dropped from the monitoring program because they were inundated by Kenney <br />Reservoir. Further, CMLRD suggested that monitor g of surface water sites SW6-1, SW31-1, <br />and SW33-1 be discontinued until one year before r~iining related disturbance occurs in Federal <br />' Coal Lease C-8424. Accordingly, Western Fuelsl submitted an application for a Technical <br />Revision on 7/22/87 to eliminate surface water monitoring at SW12-1 and SW11-2 and to <br />discontinue surface water monitoring at sites SW6~1, SW31-1 and SW33-1. Surface water <br />' monitoring is to be resumed at SW6-1, SW31-1, arjd SW33-1 one year before surface related <br />disturbance occurs in Federal Coal Lease C-84$4. The Technical Revision request has <br />' subsequently been approved. <br />' Samples collected from the surface water stations 2re analyzed for the twenty-lwo (22) water <br />quality parameters listed in Table 2-1. <br />' 2.1.2 Ground Water Monitoring Program <br />' The Deserado Mine groundwater monitoring program consists of monitoring water depths and <br />water quality from bedrock strata, the White River alluvium and the alluvium of the Red Wash <br />tributary north of Refuse Disposal Area 2/3. Bedrock hydrology monitoring is conducted at seven <br />' (7) locations while alluvial hydrology monitoring is c~nducted at the two (2) locations -the one <br />remaining after Kenney Reservoir was filled and the~ew alluvial monitoring hole near the refuse <br />' disposal areas. The locations of each of the grown water monitoring sites is shown on Plate 1 <br />in the pocket of this report. Bedrock monitoring donsists of collecting hydrologic data from <br />monitoring holes and multiple completions at each I~cation in order to monitor three zones: the <br /> <br />' 3 <br /> <br />
