boundaries can be readily identified and ~dietinguished from one another. As an example, it is not clear whether mining activities will occur in areas outside of phases 2, 3, and 4 but within the "limits of mining" line shown on the Mine Flan map. After reviewing information shown on maps prepared for the County Master Plen for this operation, it. appears that at least one irrigation ditch exists within 200 ft. of the permit area boundary but is not shown on the Mine Plan Map. Also, a review of the Wildlife Mitigation Plan Map indicates that a creek or other type of drainage channel may be situated within the permit area immediately west of the phase 5 area but is not shown on the Mine Plan Map. For these types of features and regarding permanent man- made features in general, the Mine Plan Map may need to be updated to clearly show ell creeks, presently existing buildings, oil t~ gas wells and lines, power end communication lines, end other permanent man-made structures located within 200 ft. of the permit. area. It does not appear that either the Mine Plan Map or the Reclamation Plan Map show contour lines of sufficient detail to portray the direction end rate of slope of the affected land. Also, it does not appear that specific drainage control structures that. may be associated with the Stormwater Management Plan have been included on an appropriate map. Please provide this necessary information. It does not appear that adjoining surface owners of record have been shown on an appropriate map contained in the application materiels. Please clarify. GAS WELL & OTHER PERMANENT MAN-MADE STRUCTURES Due to the proximity of the gas well to the phase 7 extraction area, the operator will either need to: 1) Demonstrate that the mining operation will not adversely affect the stability of this structure; or 2) Provide the Division with sufficient evidence of an agreement between the operator and the persons having an interest in the structure that damage to the structure is to be compensated for by the operator. An agreement covering relocation of the gas pipeline may be in existence, however our files do not appear to contain any documentation regarding the above ground portion of the facility. This requirement also pertains to any other permanent men-made structures such as barns, houses, storage sheds, etc. existing on or within 200 ft. of the effected area. MINE PLAN DETAILS A section of the mine plan states that "most of the mining in the existing pit will occur primarily during the months of March through September with some year round work". This section of the application should be clarified to indicate whether this statement refers to the phase 5, 6, & 7 area es well end in addition should be worded to be consistent with any working schedule restrictions 2
