Mr. Rolad G. Obering - 2 - December 13, 1991 <br />Exhibit C <br />Item 9: There are several issues where minimization of the disturbance <br />to the hydrologic balance is Involved. Since stripping of topsoil from <br />the western area 15 anticipated fn advance of mining and locations of <br />topsoil stockpiles are indicated to 11e along these boundaries, how <br />will runoff from these disturbed areas be prevented from moving <br />westward and southward downslope beyond permit boundaries. Describe <br />and then locate any proposed measures on map. <br />Since much of the lumber yard are <br />trucks and mining equipment, how <br />south of the berm and/or ditch a <br />prevented from moving across the <br />boundaries. Describe and locate <br />a will be subjected to use b.y haul <br />will runoff from these areas, east and <br />the base of the cut face, bye <br />work area and south beyond the permit <br />any proposed measures on map. <br />Since a berm is described in the narrative as the device to c~mtain <br />runoff from the cutslopes during mining but a ditch is indicated on <br />reclamation map E-2, some clarification in the narrative needs to be <br />made if control measures are different at different times during mining <br />and reclamation. Will the ditch indicated allow discharge beyond <br />permit boundaries or is it intended to retain all runoff within the <br />permit area as the berm is stated to provide? <br />Items 10 and 11: These are not referenced or addressed at all. Some <br />comment is necessary to insure that these issues were at least <br />considered by the application. <br />Item 12: These measures are presumably the same as requested under <br />Item 9. <br />Exhibit D <br />Item 2: The reclaimed slopes indicated on Map E-2, if approved, will <br />be required by the Division in order for the operator to secure release <br />of reclamation liability. The enclosed reclamation cost estimate, made <br />by the Division, 1s predicated on there being no grading and <br />backf1111ng necessary 1n the western active mining area, only in <br />achieving approved slopes in the eastern part of the site. A <br />commitment is therefore necessary on the part of the operator not to <br />exceed approved reclamation slopes in his mining of the western part of <br />the site in order that adjustment of the reclamation cost estimate, to <br />eliminate such steeper slopes, not be necessary. <br />Special Note, page 2 of Exhibit D: Any areas not intended to be <br />included by this application in the permit area should be omi~;ted from <br />the application and maps. If any possible use or disturbance of the <br />eastern area is anticipated, it would be wise to leave the ap~~lication <br />as is. <br />
