Question and Submission History

Decommissioning is a strict regulatory requirement at both the state and local levels. The developer is legally obligated to safely remove all battery equipment and restore the site to a stable, pre-development condition. To guarantee these funds are available, the project will establish a decommissioning bond or financial surety before construction begins. This bond runs with the project, remaining legally binding on any future owner or operator.

Three things are in progress. The Emergency Action Plan covers the response. The draft Community Benefits Plan proposes testing private wells within 1,000 feet of the work limit at the project's cost, with bottled water within 48 hours if a test shows a change linked to the site. It also proposes a payment if a home within 1,000 feet sells for less than an independent appraisal says it is worth without the facility. These are drafts and not promises yet.

The owner is responsible, and the decommissioning bond is there so that money exists even if an owner fails. The bond is required before construction, and the amount is not set yet. A third-party engineer works out the cost of removal, with the town's review. Battery systems are modular, so removal is relatively simple. The site would be restored toward forest.

The bond is meant to be reviewed on a schedule, with an engineer reassessing the cost, and the owner is responsible for keeping it adequate. We have not published the review schedule.

The estimate will be produced by an independent party and published, not generated internally, and it will be re-estimated on a set schedule across the facility's life so the figure stays current. The specific number does not exist yet; the commitments to an independent estimate, publication, and scheduled updates do.

Yes. The decommissioning bond is committed to be posted before construction, sized by the independent estimate, with no reduction for assumed scrap value. The specific form of the instrument and the town's access to it will be set during the approval process, in which the town participates with its own counsel and experts, at our cost.

The decommissioning bond covers this situation. It is posted before construction and is meant to stay with the project rather than the owner, so a sale does not remove it. The financial protection is funded up front and attached to the facility rather than to any particular owner, including ESA, because ownership is expected to change over time. The specific form of the instrument is set during the approval process.

Recovery rates vary by component and by processor, and the recycling industry will likely look different by the time this facility is decommissioned decades from now. What is committed is a decommissioning plan, filed with the application, covering removal and disposition. Verification of final battery disposition is a specific requirement we will build into the decommissioning conditions.

Removal and site restoration are covered by the decommissioning plan and bond, and tree replanting is already a committed item on the project record. The decommissioning plan filed with the application will state the restoration standard in enforceable terms.

Water use, wastewater, and chemical storage. Water use details have not been published. The facility is not a power plant and is not expected to need an ongoing supply from the town's drinking water for normal operation. Wastewater and chemical storage information has not been published. The only significant liquid in each battery unit is the coolant in its cooling system, and the coolant type has not been specified. The hydrology and stormwater studies are committed and will be published.

Stormwater, wells, and aquifers. The design being developed uses basins sized for storm events, with a commitment to no net increase in runoff and no wetland fill. A hydrogeologic study with a well inventory is underway. The draft Community Benefits Plan proposes testing wells within 1,000 feet of the work limit, with baseline testing before construction and retesting during and after it.

Emergency response. The Emergency Action Plan is being built with Charlton Fire and will be reviewed by an independent reviewer the town selects and the project pays for. It is not published yet.

Independent review and monitoring. The Energy Facilities Siting Board conducts the state review, which includes public hearings and environmental review. An independent third-party review of the Emergency Action Plan is committed. A separate independent review of the groundwater study has not been committed. Groundwater monitoring at the site is committed, with its terms in writing before construction. The state's Intervenor Support Grant Program, up to $150,000 per group for each proceeding, can pay for expert witnesses.

Financial assurance and accountability. A decommissioning bond is required before construction and stays with the project through any change of ownership. Pollution liability insurance is to be carried during construction and operation, and Massachusetts law keeps cleanup responsibility with the site's owner. Permit conditions bind any future owner. The decommissioning bond covers removal and restoration so the cost does not fall to the town.

The process. The project is in the state's required pre-filing engagement phase, with public meetings, a Citizen Advisory Committee, published records, and a comment period on the draft Community Benefits Plan that runs into 2027. Every comment receives a written response. A cumulative impact analysis, which looks at what is already in the area, is part of the state process and is in preparation.
