Exhibit D — Mining Plan <br />Paul Banks and Associates, LLC <br />Overview <br />The St. Barbara Sand and Gravel Mine permit area is approximately 364 acres, of which <br />eventually 304 acres will be mined. A plant and product stockpile area of approximately <br />30 acres and a fresh water /settling pond area of approximately 18 acres will be placed in <br />the northwest area of the permit property. Both of these areas will be mined. The plant <br />area will contain product stockpiles, crushers, screens, conveyors, a wash plant, scale <br />house, office and associated outdoor storage and vehicle and equipment parking. <br />Sand and gravel products will be mined, processed and shipped at an undetermined <br />rate. Due to the economy the mine was shut down in 2008. There is currently no <br />production taking place. The originally planned rate of production would require mining <br />about 5 to 7 acres annually. There are currently no definite plans to re -open the mine <br />and a temporary cessation notice is included with this amendment application. This may <br />be a dry mine, and dewatering will take place continuously over the life of the mine. It is <br />possible that the operator may go to wet mining using either a dragline or suction <br />dredge. Topsoil, overburden, and sand and gravel will be excavated by front -end <br />loaders, dozers or scrapers, and will be transported to the plant site by truck, conveyor, <br />or front -end loaders. <br />The post- mining land use of this property will be Tined water storage comprising 210 <br />acres of water surface and 94 acres of reseeded dry land. <br />Schedule and Sequence <br />Mining commenced in summer of 2004 and will continue for at least 25 years, depending <br />on market demand and economic conditions. <br />The initial stage of operations will include construction of the plant and associated <br />facilities in the plant area and construction of the freshwater /settling pond area. The <br />process water ponds will remain in the same area until mining and processing of the <br />remainder of the property ceases. <br />Mining will then begin east of the plant area and proceed east to the eastern permit <br />boundary setback. Once excavation reaches this setback, mining will move to the west <br />St. Barbara Sand and Gravel Mine 10031 <br />Pete Lien & Sons, Inc. 8 June 15, 2011 <br />
