Foidel Creek Mine <br />Dear Mr. Gorham; <br />As previously outlined in our letter pertaining to the supplemental <br />monitoring being done on wells GWB-1, GWB-2, and GWAP-7, TCC <br />intends to return to the normal schedule of one time per week in <br />accordance with the schedule outlined in our permit and as put <br />forth in our previous correspondence. This is based upon the water <br />levels observed in conjunction with these wells having shown very <br />little deviation, and it is anticipated that further fluctuations <br />can be monitored on a once-per-week basis as with the other sites <br />in the network. <br />TCC also wishes to notify the Division of our intent to cease <br />monitoring of well GWB-2, as the planned number of concurrent water <br />level readings have been collected for this and replacement well <br />GWB-2R. Well GWB-2R will be monitored in accordance with the <br />schedule outlined in the permit. <br />Should you have any questions or comments, please contact me at <br />your convenience. <br />Sincerely, <br />`~~~~ <br />Marcus A. iddleton <br />Environmental Specialist <br />file:\mam\tcc\fcavfmn2.not <br />
