Long <br />Division Direcor <br />RE: 1993 and 1994 Annual Hydrology Reports, Somerset Mine, ~`C-81- <br />022 <br />As per your request, I reviewed the above-mentioned reports for the <br />Somerset Mine and have the following comments or questions. <br />General Comments <br />The operator should include a discussion of the results of <br />monitoring and how it supports or contradicts the probable <br />hydrologic consequences section of the permit. Currently, the <br />operator is only re-iterating the data collected for the year. <br />Apparently the changes in the monitoring program have made it <br />easier for the operator to comply with the approved plan as there <br />appears to be a marked improvement in compliance from 1993 to 1994. <br />Please have the operator explain the following ommissions. <br />1993 Annual Hvdroloav RePOrt <br />Monitorina Freauenc <br />1.
