3. The vast majority of sampling requirements was followed. However, there are several <br />field sampling omissions involving wells DH-67B, DH-67D, DH-67abv, DH-67b1w, TC- <br />03-01 East, TC-03-O1 Upper B and TC-03-03. These omissions occurred even though full <br />suite analyses were performed. Please explain. <br />4. Alluvial wells AW-15 and AW-16 appear to be nearly dry throughout their sampling <br />history. Please discuss whether or not these two alluvial wells need to be drilled deeper. <br />5. The 2005 AHR data sheets for alluvial wells AW-15, AW-16 and AW-17 have notes <br />which state that the three wells were not affected by mining in 2005 and that all of the <br />sampling is considered to be baseline. However, the placement of gob in gob pile no. 2 <br />began in mid 2004. Please explain. <br />6. The 2005 AHR data sheets show that water sampling is limited due to problems in three <br />wells. A baler can't be used in well DH-25 due to a broken casing, DH-38 has a lodged <br />baler and TC-03-02 is silted in. Does BRL intend to refurbish these three wells? In order <br />to avoid confusion, please revise, in the next appropriate revision, the Active Monitoring <br />Wells Complete Summary Table on page 2.05-83 of the permit application to show which <br />wells have limited sampling and what is the limitation. <br />2005 Annual Mine Inflow Report <br />This report is complete and the Division has no questions pertaining to this report. The report <br />shows that mine water inflow decreased from 15 gpm in 2004 down to being nearly dry for the <br />longwall panels mined in 2005. <br />The total consumptive water use at the mine rose from 212.7 acre-feet in 2004 up to 263.0 acre- <br />feet for 2005. This rise in consumptive water use is still below the predicted value of 326.6 acre- <br />feet stated in the permit application. The water usage rate at the mine, including pond <br />evaporation and dust suppression, rose from 45.4 acre-feet per one million tons of mined coal in <br />2004 up to 64.3 acre-feet per one million tons in 2005. <br />BRL points out that BRL can handle a sudden increase in mine water inflow by using the inflow <br />water, rather than the Deer Trail Ditch water, for dust suppression. <br />2005 Bi-Annual Subsidence Reports <br />The visual inspections contained in both of the bi-annual reports state that there were no new or <br />reactivated landslides in the area. Both reports also state that there were no observed impacts to <br />any hydrologic monitoring stations from subsidence due to mining activities. <br />The data for the subsidence monument surveys were also provided. The data show that the <br />measured subsidence magnitudes are less than the predicted maximum subsidence magnitudes, <br />
