Site drainage to flow gently as sheet flow to east, consistent with pre -development <br />drainage. <br />4.5 SLOPE STABILITY <br />Permanent slopes at the Site fill areas will be no steeper than 3:1. Temporary <br />excavation slopes and temporary stockpiled material slopes may be steeper, as they are <br />temporary. All slopes will be maintained for Site safety and to minimize material erosion. <br />4.6 RECLAMATION PLAN <br />The mining and reclamation of the Site will be completed consistent with DRMS mining <br />reclamation permit #M2001-038 (Appendix 1). The mining permit and this DOP will allow <br />the reclamation of the Site into usable property, including filling portions of the Site <br />mined areas with inert fill. <br />The Site reclamation plan calls for phased reclamation, with reclamation phases <br />progressing from north to south. Reclamation phase areas will generally be less than 10 <br />acres, but will not exceed 15 acres. <br />Reclamation will include the placement and seeding of cover material overfill areas, with <br />the exception of permanent private road areas. Permanent private roads will be <br />maintained to allow Site access. <br />Additional reclamation plan information is included in the DRMS permit (Appendix 1). <br />4.7 SITE GEOLOGY <br />Site specific investigation of Site geology can be found in the Mining Plan Map (DRMS <br />mining reclamation permit #M2001-038, Appendix 1) Site test hole data indicates the <br />presence of surficial alluvial sediments, greater than 14 feet across the Site. Site test <br />holes indicate the alluvial sediments are generally composed of sand with some <br />overlying topsoil and also some interbedded clay material. The site specific investigation <br />provides data consistent with the geologic description presented in Section 3.8. <br />4.8 NEARBY WELLS <br />A listing of all the recorded wells within a one-half mile radius of the Site is presented in <br />Appendix III Wells outside of the Site should not be impacted by mining/excavation at <br />the Site, because excavations will not be advance below the water table. <br />4.9 SURFACE WATER CONTROL <br />Operational plans call for no discharge of water derived from aggregate material <br />processing, unless done so under a NPDES permit. During Site operations, all <br />stormwater will be collected on Site and typically used for dust suppression or treated <br />before being released, if the stormwater comes in contact with disturbed areas, as <br />required. <br />Bennett Sand & Gravel Pit#2 Inert Fill Page 11 of 30 <br />MOLEN & ASSOCIATES, LLC August 3, 2015 <br />
