Gratiot County commissioners send battery storage ordinance changes to planning commission after wide-ranging safety and setback debate
Summary
The board reviewed a proposed amendment to the county zoning ordinance addressing battery energy storage systems (BESS), asked planning staff to incorporate fire, drainage and emergency-response input, and voted to forward the draft with the board's requested changes to the planning commission for technical drafting and regulatory review.
Gratiot County commissioners directed staff to forward proposed changes to the county's zoning ordinance addressing battery energy storage systems to the planning commission for revision after a lengthy discussion over containment, setbacks, emergency response and regulatory reviews.
Sheila, the county planning staff member who led the briefing, told commissioners the draft ordinance is still an evolving document that must be coordinated with several agencies: "If you give us the changes, we will take those proposed changes to Spicer, have them write the language for it, and that new draft ordinance will go back to the planning commission," Sheila said, describing the next procedural step.
Commissioners and staff debated technical requirements the board wants written into the ordinance. Key topics discussed included: containment sizing (presenters recommended industry guidance such as a containment capacity of 1.5 times a spill volume), setbacks from nonparticipating property lines and dwellings (board discussion centered on 600 feet from nonparticipating property lines and an additional buffer for dwelling outer walls), restrictions near wetlands/ditches/shorelines and drain tiles, emergency shutdown and monitoring procedures, incident response and after-incident plans tied to the county emergency manager and local fire departments, sound and light standards (daytime 55 dBA / nighttime 45 dBA and dark-sky friendly lighting were discussed), and decommissioning financial assurances and schedule reviews (commissioners favored a three-year review cycle and a 25% decommissioning financial buffer).
Sheila emphasized the board needs to provide a definitive list of requested changes now so staff and the county's engineering consultants (Spicer) can draft ordinance text to circulate to regulatory stakeholders, including fire chiefs, the drain commissioner, the county emergency manager and state agencies.
After the discussion commissioners voted to send the draft, with the board's requested changes, back to the planning commission for technical drafting and coordinated review.
