(5) PHC: The impact of mining on the quantity of water in the White River will be <br />minimal. <br />This is true. The operator withdraws some water from the White River, using existing <br />water rights. Withdrawal from the river has been less than was predicted and planned. <br />(6) PHC: The local rate of runoff of surface water will increase. <br />There is no effect demonstrated in the AHR and really no way to prove this. <br />(7) PHC: There will be a temporary increase in total suspended solids (TSS) to the <br />receiving stream. <br />The temporary increase predicted in the probable hydrologic consequences section (PHC) <br />would have occurred during mine construction, but the prediction no longer applies. The <br />effect of the sedimentation ponds on the site is to make the TSS levels lower than they <br />would normally be in the area during a storm event. <br />(8) PHC: The effects of subsidence in Red Wash and Slumgullion Gulch will be <br />short-lived. <br />This proved to be true in the period 1995-97 when the azea was undermined. <br />(9) PHC: Refuse disposal effects on surface and groundwater will be minimal. <br />There are no data bearing on this prediction. <br />(10) PHC: The impact on groundwater quality will be minimal. <br />Water quality has not been sampled in the bedrock groundwater wells since 1995. Data <br />indicate that there has been no impact to alluvial groundwater. <br />low compazed to <br />Additional Comments: <br />Each year the AHR contains the comment that sampling from a list of wells was <br />discontinued. This happened in 1998. It may be good information for historical reasons, <br />but should be at least noted when they were discontinued and thus haven't been part of <br />the program for five yeazs. <br />Groundwater Points of Compliance: <br />The geologic and hydrologic situation at the Deserado Mine was reviewed with regard to <br />determining one or more appropriate "groundwater points of compliance." The Deserado <br />Mine workings lie on the south limb of a shallow syncline that plunges southeast towazd <br />the Piceance Basin. For any groundwater present, the downgradient flow will be a vector <br />resolution between the northwest dip of the beds and the southeast plunge of the syncline, <br />
