The $791.00 fee is enclosed. <br />A total of 77,271 cubic yards (cy) of on-site gravel products were produced and <br />sold from the combined Hazeltine-Road Runners Rest mine sites in 2009. Due to the <br />slow economy, sales were down from 2008, and mining proceeded at a slower pace. The <br />breakdown of the sold products is shown below. The figures do not indicate material that <br />was mined and processed but not sold. <br />Topsoil : 10,082 cy <br />Structural fill: 47,321 cy <br />Base course: 141 cy <br />Pipe bedding: 8,512 cy <br />Class 57/67 material: 2,356 cy <br />No. 57 rock 4,608 cy <br />1" to 2" rock: 1,869 cy <br />2" to 4" rock 1,681 cy <br />4" to 6" rock: 701 cy <br />Total 77,271 cy <br />Approximately 167,728 cy of fill was removed from the site and used for <br />construction projects in the area. Removal of the fill allowed access to the underlying <br />alluvial deposits. <br />In preparation for the final reclamation of the site as a water storage reservoir, <br />approximately 254,831 cy of a mixed clay and sand material were mixed and stockpiled. <br />The material, called Zone 2, will be used to line the final reservoir side slopes. This slope <br />liner material was stockpiled in five areas scattered along the pit bottom. Additional <br />material will be mixed and stockpiled in 2010. <br />CONSERVE
