<br />' March 1, 1995 for the first time since monitoring began. Crest gage and sample station SW24-1 <br />along Red Wash above the mine was washed out by a flash flood in the Spring of 1983. Grab <br />samples were collected at SW24-1 until July 1986 when a new single stage sampler was installed. <br />The stock water ponds at SW6-1 and SW33-1 are usually dry. Crest gage and sample collection <br />' stations SW1-1, SWii-1, and SW31-1 are monitored quarterly; however, run off events often <br />contain such high quantities of suspended solids that sampler tubes are plugged and the gaging <br />device silted in. Constant servicing of these stations is necessary with no guarantee that the next <br />' run off event will be measured and a sample collected. Kenney Reservoir has inundated the White <br />River alluvium 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 />!..ease C-8424. The Technical Revision request was approved. Surface monitoring stations <br />currently being monitored are SW1-1, SW11-1, SW23-1 and SW24-1. <br />Samples collected from the surface water stations are analyzed forthetwenty-two (22) water quality <br />parameters listed in Table 2-1. <br />' 2.1.2 <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 15 holes on seven <br />' (7) locations while alluvial hydrology monitoring is conducted at two locations on two (2) locations - <br />the one remaining after Kenney Reservoir was filled (QAL-5) and the alluvial monitoring hole RM-1 <br />near the refuse disposal areas. The locations of each of the groundwater monitoring sites is shown <br />' on Plate 1 in the pocket of this report. Bedrock monitoring consists of collecting hydrologic data from <br />monitoring holes and multiple completions at each location in order to monitor three zones: the <br />Upper Sandstone Facies; the Coal and Siltstone Facies; and the Lower Sandstone Facies. The <br />Upper Sandstone Facies, coal and Siltstone Facies, and Lower Sandstone Facies are referred to <br />as upper, middle and lower respectively as a matter of simplicity.
