Page 3 of 4 revised permit boundary and the proposed monitoring points for the expansion area. 3. This permit revision does not include any proposals for additional surface disturbance. Should BRL contemplate any future surface disturbance in the expansion area (gob vent borehole, fan shaft, escape shaft, etc.), the following will need to be addressed: a. The fish and wildlife information required by Rules 2.04.11 and 4.18 will need to be submitted. Specifically, BRL must address any potential Threatened and Endangered species present in the area prior to any ground disturbance. b. SHPO clearance must be obtained prior to any surface disturbance. C. The soils information required by Rules 2.04.9 and 4.06. The entire expansion area proposed in PR13 and previously approved expansion area of PR12 appear to be included in Map 9 -3 of the Bowie No. 1 permit application package. This information may be useful for insertion in the Bowie No. 2 permit. d. The vegetation information required by Rules 2.04.10 and 4.15. This information appears to have been addressed on Map 9A -1 (including supporting text) of the Bowie No. 1 permit application package, and may be useful for updating the Bowie No. 2 permit. 4. On permit page 2.04 -32i BRL describes monitoring well TC -03 -03 and indicates that this well has a pinched casing and is scheduled to be abandoned. Based on recent conversations with J.E. Stover & Associates this well has since been abandoned. Please revise the permit text accordingly and submit an abandonment report to the Division in accordance with Rule 4.07.3. Map 09 Hydrological Monitoring Location Map still shows well TC -03 -03 as an Active Monitoring Point and this should also be updated. 5. Please revise Map 09 to differentiate between wells that are inactive versus those that have been sealed and abandoned. It appears that there are a few wells that have been abandoned and permanently sealed but are still designated on Map 09 as Inactive Monitoring Points. Wells that have been permanently sealed but that are described in the permit text or listed in AHRs with regard to water quality data or other pertinent information should remain on Map 09 with the designation of permanently sealed. It will be necessary to locate these wells during future groundwater reviews. 6. The two monitoring wells installed in 2011 to provide down gradient monitoring for the western mining district are shown on Map 09 as 2010 -1 Proposed Monitoring Well. This designation should be changed to Active Monitoring Point and the two wells at this location should be identified separately on the map to show that there are actually two wells. These wells are described on page 2.04 -3 -2i. One monitoring well (2010 -113) is completed in the B -Seam with a screened interval of 1,190 to 1,220 feet. The second well (2010 -1SS) is completed in a sandstone water bearing zone located above the B -Seam with a screened interval of 1,120 to 1,140 feet. Please add the Well Completion Diagrams for these wells into the permit application package.
