The page 2.05-164 <br />appears that something which <br />Please check your copies. <br />appreciated. <br />preceded by page 2.05-163(a) (Revised <br />starts in mid-sentence. Theref e, it <br />should precede the page is m~sing. <br />Your help in resolving this will be <br />RESPONSE: <br />Pages 2.05-161 through -163 were revised with Minor Revision 92-10 <br />(Hydrologic Monitoring Plan). The inconsistency has been corrected and the <br />pages are included for your reference. Additionally, page 2.05-162 has been <br />updated to reflect the change in the NPDES Permit Number for Pond M3N. <br />MLRD CONCERN: <br />Page (existing) 2.05-166 <br />1. Paragraph two of this page indicates that overburden dewatering is not <br />expected. In fact, some local drawdown did occur. <br />RESPONSE: <br />Two wells in the Wadge Overburden (which includes the Wadge Coal) have been <br />monitored since 1979. Data from these wells seem to indicate some impact on <br />water levels from mining. The water levels have been rising from 1980 to <br />1985, probably due to cessation of mining in the vicinity of the wells in <br />1979 or 1980. Due to the wells proximity to Foidel Creek, this trend may be <br />the result of a long-term climatological trend. The data indicates that the <br />water level in the Wadge overburden varies seasonally: water levels in the <br />summer are usually higher than in the winter. Page 2.05-166 (enclosed) has <br />been revised to reflect this information. <br />MLRD CONCERN: <br />Page (Existinq) 2.06-40 <br />1. This page indicates that neutron probes are used to monitor the local <br />alluvial valley floors. It is our understanding that this is no longer <br />true. Please revise the page accordingly. <br />RESPONSE: <br />The page has been revised to reflect current monitoring conditions, and is <br />enclosed. <br />MLRD CONCERN: <br />Page (Existinq 2.06-41) <br />1. The second paragraph of this page discusses collection of agricultural <br />production data. Did this pertain to previously completed alluvial <br />valley floor determinations? Please revise this page to reflect the <br />current situation. <br />
