ITEM 7 MIX WASTES,AMEND WITH LIMESTONE,AND PLACE <br /> The off-site waste rock will be amended with limestone crusher fines already delivered to the site <br /> in Bid Item 6. The combined materials will be amended by spreading the five cubic yards evenly <br /> over the waste rock surface and incorporating the limestone to a depth of 12 inches (12")to <br /> prevent the formation of acid and leaching of metals. <br /> After the waste has been amended it will be placed in an area specified by the Project Manager <br /> within the permit boundary and graded to match surrounding topography. The placed material <br /> will not exceed a slope of 3:1. <br /> It is estimated that as many as 500 cubic yards of material will be amended with limestone and <br /> regraded within the permit boundary area. <br /> Measurement and Payment <br /> Payment for this task will be made at the unit price established in Item 7 of the Bid <br /> Schedule. Measurement for payment will be made per cubic yard of waste amended with <br /> limestone and placed in the mill foundation area. Payment for this task will be upon <br /> completion of installation and upon approval of the PROJECT MANAGER. Such <br /> payment shall be considered full compensation for all labor,materials, equipment and all <br /> other items necessary and incidental to the completion of the Bid Item. <br /> ITEM 8 COVER WITH GROWTH MEDIA <br /> The entire area where waste rock has either(1)been removed or(2)been placed will be covered <br /> with two feet(2') of growth medium,which will consist of non-mined rock,native soil and other <br /> colluvial materials present on site, which lack mineralization. The growth media will be <br /> scavenged from already disturbed areas immediately adjacent(within 50— 100 feet)to the area <br /> that is being covered. <br /> The area that is expected to require cover material is 550 square feet. So, as many as 40 CY of <br /> native material will be used to cover the area. <br /> Measurement and Payment <br /> Payment for this task will be made at the unit price established in Item 8 of the Bid <br /> Schedule. Measurement for payment will be made per cubic yard of growth media placed <br /> on disturbed areas. Payment for this task will be upon completion of installation and <br /> upon approval of the PROJECT MANAGER. Such payment shall be considered full <br /> compensation for all labor, materials, equipment and all other items necessary and <br /> incidental to the completion of the Bid Item. <br /> Page 15 of 17 <br />
