<br /> <br />J. J. Dudash - 3 - January 17, 2001 <br />8. The Division requests that Bowie Resources amend their water monitoring plan to <br />include those analytes for which receiving stream standards exist for the North <br />Fork of the Gunnison River. These should be part of the regular monitoring <br />program and monitored once annually (in addition to the other planned <br />monitoring) during the month of August, when flows are relatively low and <br />irrigation withdrawals are still active. Both upstream and downstream samples <br />should include these analytes along with active discharge points. <br />This is necessary for the Division to prepare the Cumulative Hydrologic Impacts <br />Assessment of the North Fork as required by the Rules. <br />The list of analytes includes the following: <br />dissolved oxygen pH ammonia <br />sulfide boron nitrate <br />sulfate hardness arsenic <br />chromium 111 <br />iron (dissolved) <br />manganese (dissolved) <br />chromium VI lead <br />selenium silver <br />chlorine cyanide <br />nitrite chloride <br />cadmium copper <br />mercury nickel <br />zinc <br />iron (total) manganese (total) <br />These constituents, along with Total Dissolved Solids (TDS) should be monitored <br />in the upstream and downstream sites in the North Fork of the Gunnison, the <br />Deer Trail Ditch and at any point that discharges. The detection limits used for <br />the analyses should be lower than the published limit for the receiving stream. <br />BRL -Monitoring requirements were amended on pages 2.05-76, 77, 78 The list <br />of analyses was added to page 2.05-85. <br />Wells DH-13 and DH-34B have been removed from the approved monitoring plan <br />as indicated on revised page 2.05-76. The 1999 Annual Hydrology Report (AHR) <br />indicates that these wells were destroyed by the mining operation. If these wells <br />are no longer needed, then they should be properly sealed in accordance with <br />Rule 4.07 and an abandonment report should be submitted to the Division for <br />each of these wells. <br />BRL -The DMG's comment is noted. BRL should be able to seal the wells during <br />2001. <br />10. It appears that the nomenclature for wells DH-57a, DH-57b, and DH-58a, DH-58b <br />has been changed to DH-57, DH-57a, and DH-58, DH-58a, respectively. Please <br />clarify this and ensure that all maps, permit text, and AHR information reflect the <br />correct nomenclature for these wells. <br />BRL -The DH-57, DH-57a, DH-58, DH-58a nomenclature is correct. I believe all <br />of the appropriate permit pages and maps have been revised. <br />
