i • Rationale for Approval Recommendation Page 7 Application for Stone Gravel Pit Permit No. M-97-089 5. Exhibit F -- Reclamation P/an Map -- is inadequate tsriusl a. Details of final topography are absent, only 1 contour line indicated /Sril~s) b. Fina! land use for each portion of affected land is not portrayed /srillsl Response - 5.b. -The permit application indicates rangeland post-mining land use for all affected areas. Response - 5.a. -The Reclamation Plan Map indicated two contour lines, at 40' interval. Contour line 5840' was located immediately downslope of the mining limits line, and contour line 5880', located within affected areas and incorporated within the 3H:1 V backfilled area. Pursuant to Rule 6.4.61a1, DMG requested additional information describing final slope rate and slope direction for reclaimed areas. Operator clarified that except for the 3H:1 V highwall, reclaimed areas would be final graded to provide gentle east facing slopes, approximately 1 - 3 %. Reclamation Plan Map adequately portrays the final topography, as required by Rule 6.4.6. 6. Exhibit G -- Water /nformation -- is inadequate a. Surface drainage controls are absent b. Plans for protection of surface and/or groundwater are absent c. Type and scope of impacts to water quantity and qualify are unknown d. Stormwater control plan is absent e. Plan for isolating excavated materials from surface drainage is absent f. Acid generating potential not addressed g. Possible off-site impact to Bell property from affected area runoff h. Estimate of annual wafer requirement is absent i. Projected amount from each water source not indicated j. identification of wafer source is absent k. Indication that necessary water is available, is absent 1.
