dissolved oxygen will be sampled for perennial streams (North Fork of the Gunnison and Hubbard <br />Creek). The 2007 AHR data sheets show that all of the streams were sampled for dissolved oxygen. In <br />order to avoid any possible confusion, please revise page 4 of the 2007 and future AHRs to show that all <br />streams being monitored will be sampled for dissolved oxygen. <br />The Division has no further concerns. The note on page 4 of the 2008 AHR was revised appropriately. <br />Hydrologic Pdonitoring Schedule <br />Wells B-6 and EC-7 appear in the hydrologic monitoring schedule on page 5 of the 2007 AHR but do <br />not need to be sampled since they do not appear on page 2.04-41 of the permit application. In order to <br />avoid any confusion, please delete these two stations from the AHR monitoring schedule or revise the <br />schedule to show that these two stations do not need to be sampled. <br />The Division has no further concerns. The two well notations were removed from page 5 of the 2008 <br />AHR. <br />6. Note 2 on page S of the 2007 AHR states that sites NF-I and NF-3 are to be sampled similar to the <br />sampling described in note 1, plus continuous monthly field parameters. However, page 2 of Exhibit <br />2.05-E7 states that sampling of sites NF-I and NF-3 include 4`" quarter water samples. The 2007 AHR <br />does, not contain full laboratory analyses for sites NF-I and NF-3 for the fourth quarter. Please revise <br />note 2 on page 5 of the 2007 and future AHRs to include fourth quarter full suite analyses for NF-I and <br />NF-3 and explain the absence of the fourth quarter full suite monitoring results for these two sites. <br />The Division has no further concerns. Note 2 on page 5 of the 2008 AHR was revised accordingly. <br />7. Note 8 on page 5 of the 2007 AHR states that only surface flow is to be measured at stations B-2 and B- <br />3. The surface flow information for these two stations is presented on page 7 of the 2007 AHR. <br />However, as stated on permit application page 2 of Exhibit 2.05-E7, these two stations are to be <br />sampled for flow and field parameters twice during June after tributary flow has ended. Please explain <br />why field parameters were not sampled and revise note 8 in the 2007 and future AHRs appropriately in <br />order to avoid any confusion. <br />Note: 8 on page 5 of the 2008 AHR was revised to include field parameters. However, in future AHRs, <br />please add to note 8 that the two sites will be sampled twice in June after tributary flow has ended. <br />As stated on permit application page I of Exhibit 2.05-E7 and on page 13 of the 2007 AHR, well B2D2 <br />is aground water monitoring site. However, well B2D2 does not appear in the hydrologic monitoring <br />schedule on page 5 of the 2007 AHR. Please revise page 5 to include well B2D2. <br />The Division has no further concerns. Page 5 was revised in the 2008 AHR to include the ground water <br />well D2B2 in the monitoring schedule. However, due to the sealing of the Hubbard Creek shaft in 2008 <br />and the cessation of pumping due to the sealing of the western district, Oxbow Mining stated that this <br />well will not be sampled after 2008. Oxbow stated that well D2B2 probably will be sealed in 2009. <br />Hydrologic Data Sheets <br />9. The hydrologic monitoring parameters list, on page 2.04-41 of the permit application and, also, on page <br />4 of the 2007 AHR, shows that dissolved iron and total recoverable iron are to be sampled when <br />laboratory analyses of surface water and ground water are performed. However, the 2007 AHR data <br />sheets for surface water monitoring sites only list one iron parameter. Please revise the hydrologic data <br />2
