13. It is stated in the 2007 AHR that well H-10 has been dry since 1999. However, there are no entries in <br />the hydrologic data tables for well H-10 that show any measurements during 2007 that would indicate <br />that the well was dry. Please revise the data page for well H-10 to include data for 2007. <br />14. There are no 2007 data in the hydrologic data section of the 2007 AHR for well BC-1. Please; revise the <br />hydrologic data sheets to include these data. <br />15. The discussion at the front of the 2007 AHR states that the surface water monitoring data are located in <br />Exhibit 1 and the ground water monitoring data are located in Exhibit 2. However, some of the data for <br />wells 1321) and B2D2 are located in the AHR discussion rather than in Exhibit 2. Also, the flow data for <br />sites B-2 and B-3 are located in the AHR discussion, rather than in Exhibit 1. In order to avoid any <br />confusion, the Division requests that these data either be moved to the Exhibits or their locations in the <br />discussion section be referenced in the Exhibits section. <br />16. Surface water locations S-1, C-1 and HN-1 are to have monthly flow and field parameters sampled, as <br />well as full suite analyses in the 2°d and 3`d quarters, if available. It appears that Oxbow performs the full <br />suite analyses in June and August of each year for the sites where this sampling is required. For most of <br />these sites, enough water is available during these two months to perform the full suite analyses. <br />However, at sites S-1, C-1 and HN-1, the historic data shows that no water is available during; June and <br />August, yet water is available during May. The Division requests that Oxbow attempt to perform the <br />required 2nd quarter full suite analyses in May at surface water sites S-l, C-1 and HN-1. <br />If you have any questions, please let me know. <br />Sincerely, <br />L,"4? <br />Hosep dash <br />Environmental Protection Specialist <br />cc: Marcia Talvitie (DRMS-Durango) <br />c:/word/elkcreek/2007ahradeq 1 <br />3
