<br />' September 30, 1992, that has not occurred. Crest gage and sample station SW24-1 along Red <br />Wash above the mine was washed out by a flash flood in the Spring of 1983. Grab samples were <br />' collected at SW24-1 until July 1986 when a new single stage sampler was installed. The stock <br />water ponds at SW6-1 and SW33-1 are usually dry. Crest gage and sample collection stations <br />SW1-1, SW11-1, and SW31-1 are monitored quartedy; however, run off events often contain such <br />high quantities of suspended solids that sampler tubes are plugged and the gaging device silted in. <br />Constant servicing of these stations is necessary with no guarantee that the next run off event will <br />be measured and a sample collected. Kenney Reservoir has inundated the White River alluvium <br />below Scullion Gulch and grab sample stations 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 SW11-2 <br />' be dropped from the monitoring program because they were inundated by Kenney Reservoir. <br />Further, CMLRD suggested that monitoring of surface water sites SW6-1, SW31-1, and SW33-1 <br />be discontinued until one year before mining related disturbance occurs in Federal Coal Lease <br />' C-8424. Accordingly, Western Fuels submitted an application for a Technical Revision on 7/22/87 <br />to eliminate surface water monitoring at SW12-1 and SW11-2 and to discontinue surface water <br />monitoring at sites SW6-1, SW31-1 and SW33-1. Surface water monitoring is to be resumed at <br />' SW6-1, SW31-1, and SW33-1 one year before surface related disturbance occurs in Federal Coal <br />Lease C-8424. The Technical Revision request has subsequently been approved. <br />Samples collected from the surface water stations are analyzed for the twenty-two (22) water quality <br />parameters listed in Table 2-1. <br />' 2.1.2 Ground Water Monltoring Program <br />' The Deserado Mine groundwater monitoring program consists of monitoring water depths and water <br />quality from bedrock strata, the White River alluvium and the alluvium of the Red Wash tributary <br />' north of Refuse Disposal Area 2/3. Bedrock hydrology monitoring is conducted at seven (7) <br />locations while alluvial hydrology monitoring is conducted at the two (2) locations -the one <br />' remaining after Kenney Reservoir was filled and the new alluvial monitoring hole near the refuse <br />disposal areas. The locations of each of the groundwater monitoring sites is shown on Plate 1 in <br />the pocket of this report. Bedrock monitoring consists of collecting hydrologic data from monitoring <br />holes and multiple completions at each location in order to monitor three zones: the <br /> <br /> <br />' 3 <br /> <br />
