<br />The location of each of these stations is shown on Plate 1 in the pocket of this report. Stations <br />SWi-1, SWit-1, SW31-1, SW23-1, and SW24-1 are crest stage gages with single stage <br />samplers and are designed to measure the crest of flow events and collect samples as the result <br />of those events. Stations SW6-1 and SW33-1 are the locations of stock watering ponds where grab <br />samples are to be collected. SW12-1 and SW11-2 are stations where grab samples from the White <br />' River were collected. At stations SW6-1, SW33-1, SW12-1 and SW11-2 only water samples are <br />collected for analysis. Crest gage and water sample station SW23-1 is to be monitored only if there <br />is discharge from the sediment pond (RP-1) located below the refuse disposal area. This occurred <br />1 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, SW11-1, 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 was to resume 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 was approved. Monitoring of these sites began in <br />' April, 1996 with an anticipation that mining within the lease C-8424 would take place in the near <br />future. <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 />' In May 1997, DMG issued a NOV C-97-006 citing BME for failure to maintain surface water <br />monitoring devices (crest stage gages and single stage samplers) in accordance with the permitted <br />' monitoring program. However, because of the continued problem with the maintenance of the crest <br />gage, DMG recommended that BME amend the surface water monitoring program to address how <br />1 the data will reliably be collected. After further discussions, DMG Hydrologist questioned the <br />3 <br /> <br />
