Susan Burgmaier <br />- 3 - February 15, 2013 <br />BRL - Comment noted for items a. and b. Soils information was updated on Map 4a. <br />Soil descriptions were updated on Pages 2.04 -76 -103. Vegetation boundaries were <br />updated on Map 3 based on boundaries shown on Bowie No. 1 Mine Map 9A -1. <br />4. DRMS - On permit page 2.04 -32i BRL describes monitoring well TC -03 -03 and <br />indicates that this well has a pinched casing and is scheduled to be abandoned. <br />Based on recent conversations with J. E. Stover & Associates this well has since <br />been abandoned. Please revise the permit text accordingly and submit an <br />abandonment report to the Division in accordance with Rule 4.07.3. Map 09 <br />Hydrological Monitoring Location Map still shows well TC -03 -03 as an Active <br />Monitoring Point and this should also be updated. <br />BRL - An abandonment report for well TC -03 -03 was submitted to the DRMS under <br />separate cover. <br />5. DRMS - Please revise Map 09 to differentiate between wells that are inactive versus <br />those that have been sealed and abandoned. It appears that there are a few wells <br />that have been abandoned and permanently sealed but are still designated on Map <br />09 as Inactive Monitoring Points. Wells that have been permanently sealed but that <br />are described in the permit text or listed in AHRs with regard to water quality data or <br />other pertinent information should remain on Map 09 with the designation of <br />permanently sealed. It will be necessary to locate these wells during future <br />groundwater reviews. <br />BRL - Requested changes were made to Map 9. <br />6. DRMS - The two monitoring wells installed in 2011 to provide down gradient <br />monitoring for the western mining district are shown on Map 09 as 2010 -1 Proposed <br />Monitoring Well. This designation should be changed to Active Monitoring Point and <br />the two wells at this location should be identified separately on the map to show that <br />there are actually two wells. These wells are described on page 2.04 -32i. One <br />monitoring well (2010-1B) is completed in the B -Seam with a screened interval of <br />1,190 to 1,220 feet. The second well (2010 -1 SS) is completed in a sandstone water <br />bearing zone located above the B -Seam with a screened interval of 1,120 to 1,140 <br />feet. Please add the Well Completion Diagrams for these wells into the permit <br />application package. <br />BRL - The two wells are shown separately on Map 9. Well completion diagrams for <br />these two wells are attached. <br />7. DRMS - The Active Monitoring Wells Completion Summary Table that is provided in <br />the PAP on page 2.05 -125i needs to be updated with the wells drilled in 2011. It also <br />appears that well TC -03 -03 is no longer active. Please ensure that the information <br />contained on this table is updated and accurate for the current monitoring program. <br />
