Caroline County planning commission forwards solar and battery-storage ordinance to supervisors after safety and decommissioning debate

Caroline County Planning and Zoning Commissioners voted June 18 to forward TXT-03-2602, a package of zoning amendments intended to implement recent General Assembly requirements for solar projects and associated energy storage, to the Board of Supervisors with a set of commission-recommended modifications.

The amendments would insert solar facilities and related uses into several zoning districts via the county's special-exception process, add or refine definitions (including agrivoltaics, private/public energy generation, substation and solar facility accessory), and re-adopt and revise Section 23 of the zoning ordinance to set application requirements, development standards, decommissioning rules and energy-storage safeguards. Leon Hughes, the county director, told the commission the changes are intended to make the county's ordinance comply with state law that takes effect July 1, 2026.

"The legislature said create a process for review ... and then make a determination essentially on a case-by-case basis," Hughes said, adding that mandatory review does not guarantee approval of any project. Staff also included new submission requirements: a generalized development plan, a preliminary decommissioning plan, a fiscal analysis, a real-estate-value impact study and a preliminary community outreach encouragement (state law prevents mandatory community meetings).

Fire and emergency officials described technical safety requirements the draft adds for battery-energy storage systems (BESS). Chief Lossing, the county's fire and emergency management chief, said the ordinance ties local permitting to nationally recognized standards by referencing NFPA 855 and by spelling out on-site containment and response expectations. "We don't want to put our people in there," he said, emphasizing separation distances and systems designed to limit propagation of thermal runaway. The draft requires features such as acid-proof liners for containers, concrete containment pads, minimum 50-foot separation between battery containers, a 300-foot isolation zone for incidents and NFPA 855-compliant fire-safety and monitoring systems.

Chief Lossing described response constraints in many parts of the county: "We don't have a municipal water system that covers the county," he said. "In some areas we have to bring our own water. We'd have to bring it through tankers." Commissioners discussed whether the 50-foot separation is sufficient or whether 100 feet should be required; Lossing said 50 feet was chosen as a balance between safety and site footprint but called very tight arrangements "too tight." He said deluging a container can slow heat propagation but that extinguishing depends on battery chemistry.

Residents attending the hearing urged the commission to add stricter protections. Carrie Clark of the Madison District urged the board to "make it as difficult as possible" for such facilities, citing abandoned solar projects elsewhere, visual impacts from 25-foot panels and firefighting water needs; she urged large bonds and required on-site water (she suggested 20,000 gallons). Other commenters cited long-term loss of agricultural land, groundwater and runoff concerns, and the county's limited volunteer firefighting capacity.

Commissioners and staff identified several points that the commission asked be strengthened in the draft before the Board review: clearer on-site water storage or capture provisions for firefighting (performance or tank-size standards), stronger language on decommissioning sureties and periodic recalculation of those sureties for inflation, explicit requirements for root-cause reporting after an incident and public disclosure, and a requirement that applicants provide detailed hazard mitigation and monitoring plans tied to NFPA 855.

At the meeting's close a commissioner moved to forward TXT-03-2602 to the Board of Supervisors with the commission's recommended modifications; the motion, seconded, passed by voice vote. The commission also voted to initiate companion comprehensive-plan amendments to provide policy guidance on siting and countywide caps or guidance on total acreage.

What happens next

The commission's action forwards the draft and the record of public comment to the Board of Supervisors, which will review (and may revise) the ordinance language and consider adoption. Staff emphasized the July 1 effective-date issue in state law: without a local ordinance in place by that date, energy storage accessory uses to approved solar projects could be subject only to the baseline rules in state law.

Key technical specifics recorded in the hearing

- Energy storage design: acid-proof liners on container pads; concrete pad with containment draining to lined holding; ventilation and suppression systems; NFPA 855 compliance; post-construction noise study. - Separation and setbacks: 50-foot separation between battery containers (discussed as possibly increasing); 300-foot isolation zone in incident response; substations minimum setbacks of 500 feet from principal structures and 250 feet for inverters/transformers, with the board authorized to modify setbacks on a project-specific basis. - Decommissioning and surety: preliminary decommissioning plan required with surety (escalation clause for CPI; five-year renewals noted in statute); operator financial responsibility and remediation at owner expense; requirement for a root-cause analysis and corrective-action report after an incident. - Application materials: project description, generalized development plan, fiscal analysis including local tax revenue and employment methodology, real-estate-value impact study, environmental and watershed/runoff mapping, and hazardous-materials information (material safety data sheets and a list of chemicals used were requested repeatedly by commissioners and commenters).

Representative quotes

"The legislature said create a process for review ... and then make a determination essentially on a case-by-case basis," Leon Hughes said, stressing that a review requirement does not mandate approval.

"We don't want to put our people in there," Chief Lossing said, describing firefighting tactics and the need to prevent thermal propagation between containers.

"Make it as difficult as possible for anyone to build this kind of a facility in Caroline County," public commenter Carrie Clark said, urging larger buffers, higher bonds and on-site water reserves.

The meeting record, staff packet and the public comments that were submitted with the agenda will be forwarded to the Board of Supervisors for its consideration.
