MANAGEMENT <br />January 3, 2018 <br />Clayton Wein <br />Division of Reclamation, Mining & Safety <br />1313 Sherman St., Room 215 <br />Denver, CO 80203 RECEIVED <br />Re: Bowie Resources, LLC, Bowie No. 2 Mine JAN 1 2018 <br />Annual Hydrology Report <br />Adequacy Response #1 Division of &essafety <br />on, <br />i <br />Mining <br />Dear Mr. Wein: <br />DRMS' letter dated November 8, 2017 transmitted its adequacy review for the referenced <br />adequacy response. On behalf of Bowie Resources LLC, following are its responses to the DRMS' <br />comment and concerns. <br />1. DRMS: Rule 4.05.13(4) -The Division requires that the AHR include a written <br />interpretation of the data and analytical results to be tabulated on a site by <br />site basis. Please include in the 2017 AHR, the Maximum allowable Colorado <br />Water Quality and Control Commission (CWQCC) standards for all surface <br />and groundwater monitoring locations. The information can be included <br />on the monitoring location spreadsheets, next to the baseline data. This <br />will help illustrate the written narrative in the report detailing whether or <br />not mining related impacts have occurred. <br />BRL: We do not agree that this comparison is required. What is the point of <br />obtaining a years' worth of baseline data if the benchmark for comparison is <br />the State Water Quality Standard? <br />2. DRMS: During the review of the 2016 AHR it was observed that several monitoring <br />locations had recorded flows with no corresponding laboratory data. Please explain in <br />detail the reasoning for laboratory data not being conducted or included in the <br />2016AHR.
