<br />12. In the second paragraph on Page 15-10, the fourW sentence reads "in the summer of <br />1986, 13 new monitor wells (GW-N 13 ituough GW-N22) were completed in the <br />Nucla East mining area. ". Numerically, 13 to 22 would indicate a total of 10 wells, <br />not thirteen. Please explain the discrepanry, or correct if this is in error. <br />13. In the second paragraph on Page 15-10, a sentence near the end of the paragraph <br />reads "Monitor well GW-N4R was installed as a replacement monitor well for GW- <br />N4". However, in the 1995 AHR, WFC provided groundwater level data for both <br />wells, and provided water quality data from well GW-N4, but not from GW-N4R. <br />Please explain the discrepancy and then correct the deficienry. <br />14. There are currently two different maps that show water monitoring locations for <br />Mine 1 (Exhibit 7-1) and Mine 2 (Map 2.07-1-A), however, numerous discrepancies <br />exist between the two maps. Although having two separate maps showing the <br />locations of each mines respective monitoring stations is feasible, it is preferable to <br />have one map showing all the stations with a legend stating which stations have been <br />deleted, and which are currently used for Mine 1 and Mine 2. <br />If you have questions or need additional information, please contact me. <br />Sincerely, <br />~~~ ~ <br />Harry B.
