Rating
Evidence insufficient to rate; an information request is listed
- The rule
Code computed the rating from the assessor's inputs:
present=unknown -> Unknown (abstain)
Set by the rule
- Decision
- Abstained (information request)
- The engine's reasons
- Agencies not in the register or the evidence: Indiana DNR
- Evidence state
- Missing · no evidence in hand
Conclusion withheld
- Question
- Are karst, abandoned mines, oil and gas wells, steep slopes or other geohazards present in the Brook Hollow Solar study area?
- Missing evidence
- Geotechnical investigation or desktop geotechnical study; karst, mine, or oil and gas well mapping.
- Consequence
- Foundation design, layout setbacks and possible cost or schedule exposure cannot be rated until hazards are screened.
- Information request
- Provide any geotechnical reports, state geological survey mapping, or oil and gas well and mine records covering the 1,356-acre Project Area.
- Blocks the decision
- No
Revision
Not revised.
The five inputs
Present: unknown
No evidence claims address karst, mines, oil and gas wells, steep slopes or other geohazards. Neither a geotechnical study nor hazard mapping is in the data room, so presence cannot be established or ruled out.
Cites no claim.
Extent: unknown
No evidence on any geohazard, so extent relative to the buildable area is not established.
Cites no claim.
Avoidable: unknown
No evidence on any geohazard, so avoidability by setbacks or siting is not established.
Cites no claim.
Pathway: none
Placeholder because presence is unknown; no evidence of any required approval.
Cites no claim.
Impact likely: no
Placeholder because presence is unknown.
Cites no claim.
Critique
- Verdict
- upheld
- Suggested direction for the rating
- unknown
- Summary
Abstention is correct: no claims, no as-of notes and no requirements address geohazards. Statements about the missing data room evidence are accurate. Only minor suggestions remain, such as naming specific Indiana datasets.

Issues
Severity minor · Kind missing_next_step
Next steps could name Indiana-specific sources, such as the IGWS karst and mine maps and the DNR oil and gas well database (Division of Oil and Gas). They could also add a check of the county's glacial-till setting. Coordinates 40.21,-85.69 are in east-central Indiana, where karst is unlikely, but that is not in the evidence, so abstention is still correct.
Severity minor · Kind other
The placeholder impact_likely 'no' and pathway 'none' are labelled as placeholders. Impact and cost are N/A, so they do not drive the category. The wording is acceptable.

IR-5439bed256 · Medium priority
Are karst, abandoned mines, oil and gas wells, steep slopes or other geohazards present in the Brook Hollow Solar study area?
- Missing evidence
- Geotechnical investigation or desktop geotechnical study; karst, mine, or oil and gas well mapping.
- Consequence
- Foundation design, layout setbacks and possible cost or schedule exposure cannot be rated until hazards are screened.
- Blocks the decision
- No
- Raised by
- abstention
Next steps
- Desktop review of state geological survey karst, mine and oil and gas well mapping for the Project Area.
- Commission geotechnical investigation, including pile load testing, and site visit to confirm hazards.
- Request any existing geotechnical data from the developer.
Agencies
- Indiana Geological and Water Survey
- Indiana DNR
Cost and impact
- Impact
- None given.
- Potential cost level
- N/A
- Why
Presence unknown, so cost exposure cannot be assessed.
Impact: C = cost, S = schedule. Potential cost level: L, L-M, M, M-H, H (relative to a utility-scale solar budget).
Comments
No geotechnical investigation or karst, mine, or oil and gas well mapping is included in the data room. Presence of geohazards in the Project Area is not addressed. Desktop geologic review and geotechnical investigation would settle it.
