2. General Minim Plan <br />The property boundary has been surveyed on site and the permit area will be surveyed prior to any <br />site disturbance. Map C-2 shows the mining plan. <br />The permit area will be mined by first excavating soil/overburden and stockpiling the material both <br />in berms azound the perimeter of the area as well as temporary stockpiles which will be stored on <br />the next phase to be mined. The topsoil berms will be vegetated with a standard dryland seed mix to <br />stabilize them since they may be in place for more than 1 year, and will serve the purpose of <br />visually screening the operation from the roadways and nearby houses as well as create a physical <br />barrier to keep any waters from entering or leaving the site on the surface. Temporary topsoil berms <br />will be used around the perimeter of all active mining phases except for the south in order to fully <br />screen the operation at all times. This temporary mix which will be used to vegetate the topsoil <br />berms as well as the temporary stockpiles which will be described later will consist of 15 pounds <br />per an acre of an even mix of the following seed: Slender Wheatgrass, Western Wheatgrass, and <br />Thickspike Wheatgrass. The raw gravel material will be excavated and loaded with a loader into a <br />portable crusher/screen plant where various sizes of product will be made and kept in sepazate <br />stockpiles. The portable plant will operate approximately 10 hours per day, as mining requires. The <br />mining of the deposit will occur to the limits shown on Map C-2 and will be mined to a slope of <br />2H:1 V, unless otherwise mentioned. In the reclamation, all slopes will be backfilled to a 3H:1 V <br />slope. The average annual production from the site will be 400,000 tons, which may vary depending <br />on market conditions. The processed material will be sold in three different products, a breakdown <br />of these products can be seen below in Table D-1. <br />Table D-1: Estimated Annual Production <br />Avera a Annual Product Distribution <br />roduct ons Mined Tons Sold % Reject <br />oad Base <br />oncrete <br />shalt 50,000 <br />106,000 <br />0,600 250,000 <br />90,000 <br />60,000 0 <br />15 <br />15 <br />otal 26 600 400 000 <br />Haldorson Sand and Gravel Mine <br />
