A rock chaLover <br /> 1 need to be installed over the repaired hole to deflect the water from the <br /> intersection of thhe fill. The rock apron will be constructed using on-site rock material 18" <br /> to in size. The rock apron shall be approximately 5 feet wide, 10 feet long and 3 feet deep <br /> and keyed into the surrounding material to a depth of 2 feet on both sides of the apron. <br /> Measurement and Payment <br /> There will be no measurement for payment of Task 5, Portal Repair and Rock Apron <br /> construction. Payment for this Task will be reflected in a lump sum bid under Item 5 on the Bid <br /> Schedule. This lump sum bid will cover all costs for excavating, hauling, placing and <br /> compacting the rock material as described in these specifications. <br /> Task 6 <br /> Revegetation: <br /> All areas disturbed during reclamation construction work and any other areas specified by <br /> Project Manager will be revegetated. Contractor will supply fertilizer, mulch, labor and <br /> equipment necessary for completion of this Task. Owner will supply seed. <br /> The following requirements will be adhered to: <br /> Fertilizer: Biosol Plus(7-3-3), or approved equivalent,will be added to all ground surfaces <br /> disturbed during reclamation construction. This material will be applied in advance of seeding at <br /> the rate of eight hundred(800)pounds per acre. It is estimated that 800 pounds of Biosol Plus or <br /> approved equivalent will be required. <br /> Seedbed Preparation: Seedbed preparation was accomplished as a result of Surface <br /> Roughening operations. Surface roughening will be accomplished in the following manner: <br /> - Two(2)tons of certified weed free mulch per acre will be applied to the ground surface. <br /> Mulch will be provided by Contractor and must be certified as noxious weed free or noxious <br /> weed seed free by an authorized State or County Officer. Documentation of certification must <br /> be provided to Project Manager prior to application of mulch. <br /> The mulch will be evenly distributed over the ground surface. Surface roughening will occur <br /> simultaneously with distribution of the weed free mulch in order to prevent loss of the mulch due <br /> to wind. <br /> - Roughening, or scarification, of the surface using a track excavator bucket to create numerous <br /> gouges in the ground will follow mulch application. The excavator will pull the ground surface <br /> and mulch toward the machine in a manner that creates pockets twelve inches(12")deep, by <br /> the excavator bucket width by approximately eighteen inches(18")long. These gouges must be <br /> sufficiently close so that no more than eighteen inches(18")exists between the crest of one <br /> gouge and the crest of an adjacent gouge, in any direction, both vertical and horizontal. This <br /> spacing will result in a severely disrupted surface at the mine entry areas and the access road. <br /> Revegetation efforts will occur on approximately one(1)acre, which includes all areas disturbed <br /> during this project. <br /> - 10- <br />
