Currently they are being reclaimed according to the <br />Colorado Department of Minerals and Geology regulations. <br />1 1. How are hazardous wastes disposed? Could this disposal practice affect water quality, <br />including groundwater? Please describe in detail. <br />Hazardous wastes are not disposed on-site. <br />SECTION E: MONITORING AND COMPLIANCE <br />Test <br />Performs the Testing <br />DMR testing Operator takes the sample and ships to CTE in Denver <br />WET test Operator takes the sample and ships to CTE in Denver <br />pH, Cond., Temp., Oil&Gas (Visual) Performed by Operator <br />12.

To be evaluated by Permits Unit <br />Powderhorn Coal has made a written request to the Permits Uuit for a new <br />discharge point into the Colorado River and waiting for a response. The operator <br />stated during the inspection that the new discharge point will allow underground <br />mine water to consolidate to the lowest spot in the mine and discharge at one point <br />instead of two. The site of the proposed discharge point was briefly reviewed during <br />the inspection and no environmental or physical problems were noted. The written <br />request for a new discharge point was not reviewed during the inspection. As a <br />inspection recommendation, the Permits Unit should assure that ample information <br />was supplied in the request to show that the new discharge point will have safe <br />access Cor sampling, have an accurate means of (low measurement, not be <br />detrimental to the receiving stream, and be constructed so river bank erosion will <br />not occur. <br />l3.
