Decommissioning and restoration requirements. The owner or operator of a wind energy facility or the landowner shall complete decommissioning within 12 months after the end of the useful life of a wind energy facility. Each wind turbine will be presumed to be at the end of its useful life if no electricity is generated for a continuous period of 12 months. All decommissioning expenses shall be the responsibility of the owner, operator or landowner and shall be so identified, in writing, as part of the approval process for any a wind energy facility. Decommissioning shall include the removal of each wind turbine, buildings, electrical components, and roads to a depth of 60 inches, as well as any other associated facilities. Any foundation shall be removed to a minimum depth of 60 inches below grade, or to the level of the bedrock if less than 60 inches below grade. Following removal, the location of any remaining wind turbine foundation shall be identified on a map as such and recorded with the deed to the property with the County Register of Deeds. All access roads to the wind turbine shall be removed, cleared, and graded by the owner, operator, or landowner unless the landowner requests, in writing, a desire to maintain the access road. The Township will not be assumed to take ownership of any access road unless through official action of the Township Supervisors. The site and any disturbed earth shall be stabilized, graded, and cleared of any debris by the owner, operator or landowner. An independent and certified professional engineer shall be retained by the Township to estimate the total cost of decommissioning ("decommissioning costs") with no regard to salvage value of the equipment, and the cost of decommissioning net salvage value of the equipment ("net decommission costs"). When determining this amount, the Township may also require an annual escalator or increase based on the Federal Consumer Price Index (or equivalent or its successor). Said estimates shall be submitted to the Township Zoning Officer after the first year of operation and every fifth year thereafter. The owner or operator shall post and maintain decommissioning funds in an amount equal to or greater than net decommissioning costs, provided that at no point shall decommissioning funds be less than 100% of decommissioning costs. The decommissioning funds shall be posted and maintained with a bonding company or federal or state chartered lending institution chosen by the owner or operator posting the financial security. The bonding company or lending institution must be authorized to conduct such business and be approved by the Township.
