The Mining Plan for the Oaklands Ranch Gravel Pit is as follows (Please <br />also see map): <br />This will be typical open pit gravel mine located on an upland terrace gravel <br />deposit. <br />(a) This operation of this mine will be carried out in phases. Each phase <br />will repeat the steps below. <br />The initial preparation of the surface before extraction of the sand and <br />gravel will consist of stripping the vegetation and topsoil and placing it in <br />stockpiles for use later during reclamation. Front-end loaders, scrapers, <br />and Excavators or any other suitable surface equipment will be used. <br />Following the stripping of vegetation and topsoil and saving in stockpiles, <br />earthen berms will be constructed where needed to keep the stormwater <br />from running into the Plum Creek drainage this will be part of the <br />stormwater management plan. Amore detailed view of the mining area <br />can be seen on Exhibit "C" the Mining map. <br />Extraction of the Gravel will be accomplished with front-end loaders, <br />dozers, scrapers, backhoe excavators, or any surface mining type of <br />equipment that is economically feasible for this site. <br />This is an open pit surface mine, and mining and construction equipment <br />designed for this task will be used for earthmoving and transporting on <br />site. Mining Excavation will move West and then South in the pit Area. <br />The mining will be done in such a manner as to minimize any high walls <br />and as much as possible the pit walls will be left at a 3H:1V gradient, or <br />flatter if the terrain permits. <br />During all phases, Best Management Practices must and will be followed. <br />(b) All earthmoving will be done with machinery designed for the job, eg. <br />Dozer, front-end loaders, scrapers, excavators, etc. <br />G:\Drawings\2003\03-0025\docs\GRAVEL PIT (SIP)EXHIBIT D.doc <br />
