o Water level monitoring in any converted dissolution aquifer monitoring <br />wells shall be as specified for dissolution surface monitoring wells in the <br />Water Monitoring Plan (Appendix )). <br />If water-level monitoring indicates that the Injection Zone outside of the Injection <br />Interval is being pressurized, corrective action is required as specified in Part II D <br />(1) (k) of this Pemut. <br />«** <br />6. Injection of any hazardous waste as identified by EPA under 40 CFR § 261.3 <br />is prohibited.

MONITORING, RECORD KEEPING, AND REPORTING OF <br />RESULTS <br />MONITORING: <br />(1~` Paragraph) The permittee is required to cam out the activities described in the <br />monitoringplan. The data must be reported and maintained as provided in Section II D.4 <br />of the Permit. The Ground Water. Surface Water. and Process Monitoring Plan (Water <br />Monitoring Plan), dated September 2004, has been incorporated into the Permit as <br />Appendix I <br />(2nd pazagraph) The Water Monitoring Plan includes ground-water monitoring, for the <br />Piceance Site (solution well field and upper plant) and process monitoring for mining <br />operations at the Piceance Site. It also contains monitoring provisions for surface ponds <br />and the pipeline, which aze not covered by the Permit. <br />~*~ <br />(4'"paragraph, modified 5"'pazagraph replaces deleted 4'" paragraph) The Water <br />Monitoring Plan addresses monitoring for the current mining area (0-5 yeaz panel). <br />Subsequent monitoring plans, applicable to the future commercial mining azeas (6-30 <br />yeaz panels), will be developed prior to mining in those areas. As additional monitoring <br />data is collected and analyzed, changes (increase or decrease) to the monitoring plan may <br />be appropriate. Changes could include monitoring parameters, sampling or analytical <br />methods, frequency of monitoring, or. the number and location of monitoring points. A <br />reduction of the current monitoring requirements would be made only after a review of <br />the data demonstrates that the current monitoring requirements aze: <br />1) redundant <br />For example, where other monitoring locations or data already provide adequate <br />monitoring coverage, a reduction in monitoring could be appropriate. <br />Draft Modification No. 9 UIC Area Permit No. C030858-00000 Page 9 of 44 <br />
