September 30, 1994, that has not occurred. Crest gage and sample station SW24-1 along Red Wash above the mine was washed out by a flash flood in the Spring of 1983. Grab samples were ' collected at SW24-1 until July 1986 when a new single stage sampler was installed. The stock water ponds at SW6-1 and SW33-1 are usually dry. Crest gage and sample collection stations ' SWi-1, SW11-1, and SW31-1 are monitored quarterly; however, run off events often contain such high quantities of suspended solids that sampler tubes are plugged and the gaging device silted in. Constant servicing of these stations is necessary with no guarantee that the next run off event will be measured and a sample collected. Kenney Reservoir has inundated the White River alluvium below Scullion Gulch and grab sample stations SW11-2 and SW12-1. ' Following review of the Second Annual Deserado Mine Hydrology Report, Colorado Mine Land Reclamation Division (CMLRD) suggested that surface water monitoring sites SW12-1 and SW11-2 be dropped from the monitoring program because they were inundated by Kenney Reservoir. Further, CMLRD suggested that monitoring of surface water sites SW6-1, SW31-1, and SW33-1 be discontinued until one year before mining related disturbance occurs in Federal Coal Lease ' C-8424. Accordingly, Western Fuels submitted an application far a Technical Revision on 7/22/87 to eliminate surface water monitoring at SW12-1 and SW11-2 and to discontinue surface water ' monitoring at sites SW6-1, SW31-1 and SW33-1. Surface water monitoring is to be resumed at SW6-1, SW31-1, and SW33-1 one year before surface related disturbance occurs in Federal Coal Lease C-8424. The Technical Revision request was approved. Surface monitoring stations currently being monitored are SW1-1, SW11-1, SW23-1 and SW24-1. ' Samples collected from the surface water stations are analyzed for the twenty-two (22) water quality parameters listed in Table 2-1. 2.1.2 The Deserado Mine groundwater monitoring program consists of monitoring water depths and water quality from bedrock strata, the White River alluvium and the alluvium of the Red Wash tributary north of Refuse Disposal Area 2/3. Bedrock hydrology monitoring is conducted at 15 holes on seven ' (7) locations while alluvial hydrology monitoring is conducted at two locations on two (2) locations - the one remaining after Kenney Reservoir was filled (QAL-5) and the alluvial monitoring hole RM-1 ' near the refuse disposal areas. The locations of each of the groundwater monitoring sites is shown on Plate 1 in the pocket of this report. Bedrock monitoring consists of collecting hydrologic data from monitoring holes and multiple completions at each location in order to monitor three zones: the ' Upper Sandstone Facies; the Coal and Siltstone Facies; and the Lower Sandstone Facies. The Upper Sandstone Facies, coal and Siltstone Facies, and Lower Sandstone Facies are referred to as upper, middle and lower respectively as a matter of simplicity. The Deserado Mine coal seams ' 3 J
