Brian Watterson Page 2 04/29/05 provide the necessary data for the Yampa River (#4). For #7, please provide affirmative evidence that a Phase III bond release application is not currently under review nor will any Phase III application be submitted any time prior to January 1, 2007. 3. On Table 1 of the AHR, rather than a measurement of water level for WF-1, WF- 2and No. 1 Strip Pit, the Table should likely read "Flow" under Frequency of Measurement. 4. The Okie Plaza well was undermined in 1994 and therefore eliminated from the hydrologic monitoring plan. Page 2.05-23 requires that wells that will be mined through will be sealed prior to undermining. Please submit an abandonment report for this well in accordance with Rule 4.07.3. 5. Please submit a minor revision to include hardness in the parameter lists on Tables 8, 8A, and 9A. Monitoring Freguencv The monitoring frequency as determined by Appendix D, Temporary Cessation Monitoring Plan (TC Plan) pages D-1 and D-2, June 21, 2001 is as follows: NDPES Outfalls • All NDPES outfalls are monitored at a frequency that is the same as the active mining monitoring plan (pages 1-14 of Exhibit 29). 6. Please provide a copy of the current CDPS permit CO-0034142 for the Division copy of the mine records. 7. Please explain the statement under Section 3.2.2 Ponds, "There was no discharge from the sediment ponds in 2004." The Division understands that outtalls 003, 022, and 024 are point source discharge locations from sediment ponds. If this is not correct, please explain. The frequency of monitoring CDPS outfalls appears in compliance with the requirements of the CDPS permit. Surface Water Monitorino Two surface water sites, WF-1 and WF-2, are monitored along the Williams Fork River. During temporary cessation, the monthly and/or quarterly requirements are reduced to one annual visit to each station. 8. Please provide the lab sample sheets for the samples retrieved for the date 8/13/2004, or for another date between July 20 and August 30. It appears that 2003 data may have been inadvertently reported for 2004. . Until the operator provides this information, compliance with the sampling frequency cannot be determined for the two surface water sites.
