7, 2003 log. In addition, the differential temperature from fluid level to 1650 FFS <br />increased from 10 to 18 degrees F. The temperature log indicates cement jobs <br />decreased or stopped the downward flow of aquifers and temperature profile was <br />similar to historical data. Also enclosed is a CBL indicating good to excellent <br />bond is present from 900 to 1650 FFS. <br />A work -over report ( #2) is attached from Mr. Rod Storey, NSI Drilling Supervisor, <br />which states "temperature log shows normal temperature increase" and "cement <br />bond log shows good cement and good isolation of aquifers from 900 - 1650" FFS. <br />Plugging and abandonment of several NSI wells (4 -3H, 3A -4H and 1A -4HI) is <br />planned in the next two months. During the P/A work, NSI will clean-out the <br />lower portion of 3M -TDR and fill casing to surface with water, and obtain more <br />complete logs. <br />In summary, temperature and CBL logs indicate 3M -TDR has been successfully <br />cemented and the Dissolution Surface, B- Groove, A- Groove and Perched aquifers <br />have been isolated in 3M -TDR. 3M -TDR cables #2 and 3 continue to be <br />monitored for subsidence data. <br />If there are any questions please contact Mr. Rod Storey or me. <br />Sincerely, <br />Ed Baker, REM <br />EHS Manager <br />CC: EPA <br />BLM <br />
