11. Array support posts are generally lightweight "I" beam sections installed deep into the <br /> ground. Crew productivity is approximately 30 posts per hour, and the same crew and <br /> equipment should have similar productivity removing the posts, resulting in a per ton cost of <br /> approximately $13.38. When salvage values have not been recognized the costs for processing <br /> metal to size and the hauling cost to a more distant recycling facility are generally not included, <br /> but the minimum decommissioning financial security controls by such a large margin that the <br /> lower price for removals and freight are not shown. <br /> 12. The underground collector system cables are placed in trenches with a minimum of four <br /> feet of cover. <br /> 13. To reduce tracking of sediment off-site by trucks removing materials, we have included a <br /> stabilized construction entrance price to the "Site Restoration" section based on state DOT bid <br /> prices for similar items. <br /> 14. Perimeter control pricing is based on a sediment fence placed on the downgrade side of <br /> the work area perimeters and protecting wetlands and drainage swales within the project area. <br /> 15. No topsoil will be removed from the landowner's property or used on other landowner's <br /> property during decommissioning. The majority of the Project site is not anticipated to have <br /> been compacted by heavy truck or equipment traffic so no topsoil will need to be imported, <br /> and very few areas will need to be de-compacted. <br /> ENTERPRISE <br /> �7 ENERGY <br />
