Tessmer Coyle Engineering, Inc. Civil engineering, stormwater and transportation | New Philadelphia, Ohio Preliminary Decommissioning Plan and Cost Estimate Tamsin Ridge Solar and Storage Project, Harrison Township, Carroll County, Ohio Prepared for Northfold Energy Partners, LLC. March 20, 2023. 1. Purpose and requirements This plan describes how the 120 MW solar facility and the 60 MW / 240 MWh battery energy storage system will be removed and the land restored at the end of the Project's life. Under ORC 4906.21 to 4906.222, enacted by SB 52, the applicant must submit a comprehensive decommissioning plan prepared by a registered professional engineer to the OPSB at least 60 days before construction, with a schedule that ends within 12 months after the facility stops operating, and a full cost estimate recalculated every five years. Before construction it must post a performance bond, with the Board as obligee, equal to the estimate; the bond is updated every five years and is never reduced. The leases also require removal and restoration within 12 months after they end. 2. Decommissioning triggers and schedule Decommissioning starts when the facility has generated no electricity for 12 consecutive months, when the leases end, or when the owner decides to retire it. Removal and restoration will take about 9 months: equipment removal (months 1 to 6), foundations, cables and roads (months 4 to 8), and soil restoration and seeding (months 7 to 9). 3. Removal and restoration • Modules, trackers, inverters, the substation, the battery enclosures, fencing and the operations building are removed. • All piles are pulled completely. Concrete foundations are removed to 36 inches below grade. • Underground collection cables are removed to 36 inches; deeper cables are removed unless the landowner elects in writing to leave them. • Gravel roads are removed and the subsoil decompacted, unless a landowner keeps a road. • Topsoil is restored, compaction relieved by deep ripping, drain tile repaired, and the land seeded to a cover crop for return to farming. • Modules are sent for reuse or recycling. Battery enclosures are returned to the manufacturer or a licensed recycler under its take-back program; damaged batteries are handled as hazardous waste.
