channel rock will need to be repaired. Hand labor is required to repair the channel. <br />CONTRACTOR must supply the laborer and any hand tools required to complete the <br />-task. Rock washed immediately downstream will need to be moved back on the <br />drainage channel. A trench shall be constructed perpendicular to the channel to a depth <br />of 3 feet deep, 2 feet wide and 15 feet long under the direction of the PROJECT <br />MANAGER. Rip rap ranging from 18 inches to 24 inches in diameter will be placed in the <br />trench. All remaining rock shall be placed in the channel to achieve the specification <br />noted in Drawing 1, Slope Drainage Course Cross Section and Plan View <br />Measurement and Payment <br />There will be no measurement for payment of Task 4, Drainage Channel Repair. <br />Payment for this Task will be reflected in a lump sum bid under Item 4 on the Bid <br />Schedule. This lump sum bid will cover all costs for drainage channel repair as <br />described in these specifications. <br />Task 5 <br />Slope Scarification <br />The mine bench out slope and access roads will be hand scarified in order to disrupt the <br />slope surface, and to create small shelves and other areas for seed to germinate. Care <br />shall be taken not to disturb established shrubs or sustained patches of vegetation. See <br />Site Overview Plan Map for further detail. <br />Hand -crews will be used to create small benches or shelves on the out slopes. The <br />shelves will be ten inches (10 ") wide (perpendicular to the fall of the slope; on contour) <br />by approximately four inches (4 ") deep (cut into the slope) creating a backwall of <br />approximately four to six inches (4 " -6 ") in height. Each shelf must be constructed so that <br />the base is horizontal and flat. The benches will be created in an offset pattern from top <br />to bottom of the slope. Shelves will be no further than two feet (2') apart, from edge to <br />edge perpendicular to the fall of the slope (on contour), and no further than four feet (4') <br />apart as measured parallel to the fall of the slope. Crews must start at the top of the <br />slope crest, and work down slope. <br />Measurement and Payment <br />Scarified areas will be measured to the nearest 0.1 acre and paid at the unit price bid on <br />the Bid Schedule Item 5. The price bid shall include all costs for labor, materials, <br />equipment and all other items necessary for scarification as described in these <br />specifications. Payment for this task will be made only for the unit price shown under <br />Item 5 of the Bid Schedule. Payment shall be as this task is completed and approved <br />by the PROJECT MANAGER. <br />Task 6 <br />Revegetation <br />The #2 Portal Backfilled Area and access roads scarified during completion of Task 5, <br />Slope Scarification, will be revegetated according to the Revegetation Requirements in <br />the General Bid Specifications Section 20.0, except as modified by these Special <br />Conditions. Approximately one (1.0) acre on the Fruita Mine will require revegetation. <br />The areas include the #2 Portal Backfilled area (0.60 acres), 3 segments of the access <br />road (0.30 acres) and the lower pond trench area (0.10 acres). All seed, fertilizer and <br />As of 01/08/09 <br />
