Seneca II-W Prelim. Adequacy - 7 - March 5, 1985 4. All state construction contracts require that the contractor keep a superintendent on the job at all times that labor is being performed. As such, the estimated figure provided on Page 13-76 for contractor`s supervision under the Miscellaneous Project Costs portion of the cost estimate should be adjusted to more accurately reflect the number of hours a superintendent will be required to be on the job. Reclamation Plan -Topsoil Redistribution - Rule 2.05.4(2)(d) 1. The application states on Page been replaced, the area will be This section of the application monitoring and contour ripping final graded areas prior to the 13-15, Volume IX that "after topsoil has monitored for slippage and erosion." should be revised to also provide for any slippage surfaces identified on the replacement of topsoil. Post-mining Land Uses - Rule 2.05.5 The post-mining land use plan portion of the application must be amended to include a copy of the comments concerning the proposed use by the legal or equitable owner of record of the surface of the proposed permit area and the State and local government agencies which would have to initiate, implement, approve, or authorize the proposed use of the land following reclamation. Probably Hydrologic Consequences - Rule 2.06.6(3) 1. 0n page 7-182 under Water Levels, the applicant talks about .. no ground water rights within the zone of influence that could be affected by the decline." The zone of influence appears to refer to the 100 foot limit established as the limit of maximum pit inflow. This is not the maximum drawdown (i.e, the cone of depression) and does not constitute the potential zone of influence. Peabody should estimate the maximum drawdown and specifically address the Temple Well and effects that mining could have on this well. 2. The Temple Well is not addressed on page 7-188. On page 7-58 it is stated that no determination could be made of the well depth or geologic aquifer, therefore this well cannot be ruled out as potentially being affected by mining. This should be addressed along with mitigative measures. 3. Are any of the water rights listed in Table 7-64 as domestic currently being used for domestic water supply? In particular, the Olson Spring is listed as domestic and is downstream of mining on Dry Creek. After mining, this water quality could be affected by spoils aquifer discharge to the surface water system.
