COLORADO <br /> Division of Reclamation, <br /> Mining and Safety <br /> Department of Natural Resources <br /> February 12,2020 <br /> Basil Bear <br /> Bowie Resources,LLC <br /> P.O. Box 1488 <br /> Paonia, CO 81428 <br /> Re: Bowie No.2 Mine,Permit C-1996-083, <br /> Review of BRL response to Division adequacy for 2018 AHR <br /> Dear Mr. Bear: <br /> On February 10,2020,the Division received the BRL adequacy response related to the 2018 AHR. (The <br /> response was submitted by Tamme Bishop of J.E. Stover&Associates on behalf of BRL.) The two item <br /> numbers below correspond to the numbers in the BRL response. <br /> 1. In my first adequacy letter,I stated: <br /> It is not clear to the Division why some ponds and drill holes were not monitored. Comparing the <br /> Hydrologic Monitoring Plan of the PAP to the sites included in the 2018 AHR, it appears that the <br /> following locations were omitted from data in the AHR:Ponds 36-3 and 36-6;Drill Holes 15, 25, 34B, <br /> and 38. Please explain. <br /> BRL responded that the approved pages in the PAP,namely 2.05-130 and 2.05-131,indicate that drill <br /> hole 34B was destroyed in 1999 and that other monitoring locations have been suspended. I partially <br /> agree with this. However,it is unclear where the PAP states that drill holes 15,25, and 38 were <br /> suspended. Please elaborate. <br /> 2. In my first adequacy letter,I stated: <br /> It is not clear to the Division why some parameters in the surface water list in the Hydrologic Monitoring <br /> Plan of the PAP are not included in the 2018 AHR data. Please explain. Examples include Dissolved <br /> Oxygen at Deer-low and Dissolved Iron at HUB-low. <br /> BRL responded that dissolved iron concentrations at the Deer-low site will be reported in future AHRs. <br /> In my initial review,it was my intent that a comprehensive comparison be made by BRL of the <br /> parameters approved for sampling and the parameters actually analyzed and reported to insure <br /> compliance with Rule 2.05.6(3)(b)(iv). This comparison, and adjustments to your monitoring <br /> activities, as necessary, should be done prior to additional sampling in the third quarter of 2020. <br /> Thank you, <br /> Robert D.
