The assessor's comments
Nearby residences and farmsteads rely on private wells in the shale and sandstone aquifer. Ohio EPA mapping shows no source water protection area within the parcels. No fire hydrants in the area; nearest pressurized water is in Carrollton, about 4 miles away. No well survey is in the data room.
Worst case
If what is pending at the cut-off went badly, the same rule gives a higher rating.
- Scenario
The survey finds private wells within pile-driving offsets, or the BESS needs a new on-site well, so testing and restricted methods remain likely.

2What the record shows
The five inputs
Present: yes
Nearby residences and farmsteads rely on private wells in the shale and sandstone aquifer (C-ae204b1b36). Ohio EPA mapping shows no source water protection area within the parcels (C-afa9ffa993), which does not conflict: private wells are nearby, not protection areas. No hydrants exist and the nearest pressurized water is about 4 miles away (C-04a3f6e338), so fire water will need tanks or hauling.
Cites C-ae204b1b36, C-afa9ffa993, C-04a3f6e338
Extent: peripheral
Private wells are described as nearby, and no protection area lies within the parcels (C-afa9ffa993, C-ae204b1b36). No document places wells within the buildable area, so no protected resource governs the layout.
Cites C-ae204b1b36, C-afa9ffa993
Avoidable: yes
Offsets from wells, a pre-construction testing offer (C-5a262c9439) and hauled or tank-stored fire water (C-04a3f6e338) can remove the exposure. No documented limit on the aquifer or the water supply.
Cites C-5a262c9439, C-04a3f6e338
Pathway: standard
Well testing offer for private wells within 1,000 feet of pile driving (C-5a262c9439) and routine well or water-use registration if an on-site source is chosen. No contested approval is documented.
Cites C-5a262c9439
Impact likely: no
Wells are nearby but none is documented inside normal pile-driving offsets, and no protection area exists on the parcels (C-ae204b1b36, C-afa9ffa993). Solar pile driving and a hauled fire water supply are unlikely to affect neighbouring supplies. Testing is pathway and cost, not impact.

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.
