The assessor's comments
Ohio SB 52 county veto power reaches the project; the PJM exemption does not apply. Commissioners may prohibit the facility or limit its boundaries within 90 days of the county meeting. No restricted-area resolution for Harrison Township was found as of 2023-03-28. Commissioners took no action at the 2023-05-12 meeting. Sources are not exhaustive.
Worst case
If what is pending at the cut-off went badly, the same rule gives a higher rating.
- Scenario
Commissioners adopt an ORC 303.62 resolution prohibiting the facility or designate Harrison Township a restricted area, barring the OPSB application.
- Step still pending
- Board of County Commissioners decision within 90 days of the 2023-05-12 county public meeting

2What the record shows
The five inputs
Present: yes
The SB 52 county veto and restricted-area power reaches the project: the PJM exemption does not apply because AH1-931 entered window AH1 (C-d95cdabeb7, C-5d2a9e4a3a). Commissioners may prohibit the facility or limit its boundaries within 90 days of the county meeting (C-33a9601349) and may designate restricted areas (C-a1e4999eda). Counsel found no restricted-area resolution for Harrison Township as of 2023-03-28 (C-0fe7f42a17). The absence of county and township zoning (C-09acff9294) does not touch the separate ORC 303.57-303.62 powers (C-68cb5c0292), so the absence claims do not conflict with presence of the veto power.
Cites C-d95cdabeb7, C-5d2a9e4a3a, C-33a9601349, C-a1e4999eda, C-0fe7f42a17, C-09acff9294, C-68cb5c0292
Extent: unknown
The veto power reaches the project, but the room holds no dated record of the county or adjoining counties using it, or of denials by the state siting authority, in the prior 24 months. The Board took no action at the 2023-05-12 meeting (C-27017a88b6). Core is not established and the record does not support peripheral, so extent is unknown.
Cites C-d95cdabeb7, C-27017a88b6
Avoidable: partly
The project has no exemption, grandfathering or vested protection (C-d95cdabeb7). The county could act before approval within the 90-day window (C-33a9601349, C-27017a88b6). No bar was found over the site as of 2023-03-28 (C-0fe7f42a17), so a bar is not yet shown. Residents have asked the Board to act (C-24271b647d); that opposition is rated in CO-02 and used here only as context.
Cites C-d95cdabeb7, C-33a9601349, C-27017a88b6, C-0fe7f42a17, C-24271b647d
Pathway: standard
No restriction covering the site was found as of 2023-03-28 (C-0fe7f42a17), and no denial by OPSB or the county of a same-technology project is recorded. Commissioners had taken no action at the meeting (C-27017a88b6). Individual and prohibition are not supported as of the cut-off.
Cites C-0fe7f42a17, C-27017a88b6
Impact likely: yes
A local veto/restriction power reaches the project, which is sufficient for yes under this row's guidance (C-d95cdabeb7). The county meeting under ORC 303.61 has occurred and a decision is pending (C-27017a88b6). Neighbours' stated intent to intervene is rated in CO-02 and not relied on here.

Under Ohio's SB 52 (effective 2021-10-11) the board of county commissioners may designate restricted areas that bar large solar facilities, and within 90 days of the required county public meeting may prohibit the facility or limit its boundaries; two voting ad hoc local members sit on the Power Siting Board. This power reaches the project: the SB 52 Section 4 PJM exemption does not apply, because position AH1-931 entered window AH1 (closed 2021-09-30); under the operator's published study timing its system impact study could not be complete before 2022-04-30.

6Basis and limits
This report is a desk review of the documents quoted above, as the engine read them for an information cut-off of 2023-08-01.
It is not a field survey and not a modelled study: this review made no site visit and ran no acoustic, hydraulic or other model. Where the record is silent, the report says what is missing; it does not fill the gap.
Every statement, figure and quote is the engine's record as written. The headings and connecting words are fixed text of this room, the same in every report.
