• CONCLUSIONS <br />Hydrologic sampling of two natural springs occurring below the mine site, one spring <br />within the mine site, and groundwater wells above, within, and below the mine site <br />showed no significant changes in parameter values during the 1999 water yeaz that would <br />indicate concerns with water associated with the azea of the coal mining operation. <br />Springs 3 and 4 both flowed during the second sampling event in April of 1999, though <br />Spring 4 was dry in October 1998. Flow from the Haukoad Spring was very minimal <br />during the sampling in November 1998. Groundwater well levels were not significantly <br />affected by the surface water moisture regime. Depth to water in well 94-1 increased to <br />76 feet in April 1999, however this magnitude in change in depth occurred the prior water <br />yeaz also. No significant changes were observed in the chemical composition of the <br />springs or groundwater wells. <br />SEDIMENT POND INSPECTIONS AND DISCHARGES <br />The Cazbon Junction Mine has two sediment ponds. 001 and 002. Jim Hendricks of <br />Oakridge Energy inspected both sediment ponds during January 1999, April 1999, and <br />July 1999. No quarterly inspection occurred during the fourth water yeaz quarter. <br />Sediment pond inspection reports are included for water yeaz 1999. No significant <br />concerns were identified during the inspections. <br />Neither sediment pond discharged during water yeaz 1999 as reported on CDPS discharge <br />monitoring reports. These reports are appended for the 1999 water year to the end of this <br />report. No reports were filed for the fourth water year quarter of 1999. The stormwater <br />management plan report to the Colorado Department of Heal[h and Environment is being <br />sent under sepazate cover. <br />i <br />-~- <br />
