Baldwin planning board conditionally approves 995-kW Emerald Trail solar project, requires wetland confirmation and decommissioning bond

The Baldwin Planning Board on April 23 voted to approve a conditional use permit (CUP) for Emerald Trail LLC’s 995-kilowatt ground-mounted solar array, but set a package of conditions the applicant must satisfy before construction. The board’s approval was contingent on confirmation of wetland boundaries, completion of a state decommissioning permit and insurance bond naming the town as a beneficiary, and sign-off from the town road commissioner and the fire chief.

Mike Atkinson, representing Kadia Emerald and the Emerald Trail Solar Project, told the board the project would occupy about 13 acres, with approximately nine acres planted with solar panels and about 3,000 modules connecting to CMP on Route 113. "This is a just under one megawatt ground-mounted fixed tilt solar project," Atkinson said, and described planned 100-foot vegetation buffers along Route 113 and a minimum of roughly 130 feet of existing vegetation along Deacon Road to screen the array.

Why it matters: board members said the remaining outstanding items relate to legal and safety protections that affect the town’s long-term liability and neighbors’ access. The board identified wetlands confirmation and a state-required decommissioning bond — with the town listed as a beneficiary — as conditions to be verified before any building permit is issued.

Board members discussed specific conditions the applicant must meet. These include: - Submission of an updated wetland delineation and a commitment that any new wetland findings will reduce (not expand) the project footprint; - Proof that the applicant has obtained the state decommissioning permit and posted the required bond or insurance that names the town of Baldwin as a beneficiary; - Coordination with Baldwin Road Commissioner Chris Harrington to review and, if necessary, stabilize the Deacon Road entrance and the access route for heavy construction vehicles; - A requirement that the fire chief, Jacob Bradway, review rapid-shutdown procedures and firefighting access and that any agreed mitigation be in place before construction; and - Documentation showing general-contractor insurance and, if needed, local-contractor coverage, plus an annual notification to the town of the project owner and the company contracted for operations and maintenance.

Atkinson said the project team will send an environmental scientist to the property next week to confirm wetland boundaries mapped in 2020 and that, if boundaries differ, the project footprint would be adjusted inward. He also said the project would participate in Maine’s net energy billing program, allowing CMP account-holders to buy project energy credits at a discount.

Residents at the hearing raised environmental questions about panel composition and disposal. A commenter worried about cadmium compounds in panels and potential contamination if panels were damaged, saying, "Cadmium chloride is getting into water... we’re polluting ourselves." Atkinson said the site is not over water and that the project will research panel composition and attempt to avoid panels that contain telluride/cadmium where practicable. He also noted that state decommissioning rules require an estimated removal cost and a bond to cover removal if a project is abandoned.

The board moved and voted to accept the CUP with the conditions discussed and directed the planning-board secretary to reduce the conditions to writing; formal signatures will follow when the written package is complete. The board also emphasized that construction may not begin until all conditions — including the wetland confirmation, state decommissioning permit with the town named beneficiary, and required road and fire sign-offs — have been satisfied.

The board said it expects to receive the consolidated package in writing before the next steps are taken; the applicant said some administrative items could be ready earlier to preserve equipment-order windows for tax purposes.
