Code computed the rating from the assessor's inputs:

- Agencies not in the register or the evidence: Ohio EPA

Conclusion withheld
- Question
- What is the NAAQS attainment status of Carroll County, OH, and does the project need an air permit or exemption?
- Missing evidence
- EPA Green Book or Ohio EPA attainment record; Ohio EPA air permit, registration or exemption determination.
- Consequence
- Without it, nonattainment or conformity constraints and generator permitting cannot be ruled in or out.
- Information request
- Provide any air quality review, attainment designation record, and equipment list showing emergency generators.
- Blocks the decision
- No
Worst case
If what is pending at the cut-off went badly, the same rule gives a higher rating.
- Scenario
Area is in attainment but a permitted emission source such as an emergency generator requires an Ohio EPA registration or permit-by-rule; nothing in the evidence suggests a nonattainment designation.
- Step still pending
- Attainment status check and air permit applicability review for any emergency generator
- Inputs in the worst case
- Extent peripheral · Avoidable partly · Pathway standard · Impact likely yes
- The rule on the worst case
- point Unknown; worst case: impact_likely=yes -> 2
Revision
Not revised.
The five inputs
Present: unknown
No attainment-status record, air permit determination or other claim on air quality is in the data room, so the area's NAAQS status is not established.
Cites no claim.
Extent: unknown
No evidence on whether the site lies in a nonattainment or maintenance area.
Cites no claim.
Avoidable: unknown
No evidence on designations or on proposed emission sources such as emergency generators.
Cites no claim.
Pathway: none
Placeholder because present is unknown.
Cites no claim.
Impact likely: no
Placeholder because present is unknown.
Cites no claim.
Critique
- Verdict
- upheld
- Suggested direction for the rating
- same
- Summary
Abstention is correct because the data room has no air quality evidence. Only minor wording problems: the worst case asserts attainment and a generator pathway without support, and the next steps omit open-burning and fugitive-dust rules. The category stays Unknown.

Issues
Severity minor · Kind unsupported_statement
The worst-case scenario states 'Area is in attainment' and 'nothing in the evidence suggests a nonattainment designation'. The data room has no air quality evidence, so this is silence, not support. The point rows correctly abstain, but the worst case treats attainment as the baseline. It should be framed as a hypothetical to be confirmed by the Green Book check.
Severity minor · Kind unsupported_statement
The worst case and the comments assume an emergency generator comes with the battery storage and that an Ohio EPA registration or permit-by-rule applies. No claim or requirement supports a generator or that pathway; it is model knowledge. Phrase it as 'if any generator is proposed'. The worst case is also arguably understated: a nonattainment or maintenance designation is not considered, and the pending check could find one.
Severity minor · Kind missing_next_step
Next steps omit Ohio open-burning and fugitive-dust restrictions for construction, which the row names. They also omit confirming whether the project needs any Ohio EPA air permit or exemption beyond generators. Both are small additions.

IR-d977f3a3e8 · Medium priority
What is the NAAQS attainment status of Carroll County, OH, and does the project need an air permit or exemption?
- Missing evidence
- EPA Green Book or Ohio EPA attainment record; Ohio EPA air permit, registration or exemption determination.
- Consequence
- Without it, nonattainment or conformity constraints and generator permitting cannot be ruled in or out.
- Blocks the decision
- No
- Raised by
- abstention
Next steps
- Confirm Carroll County NAAQS attainment status via USEPA Green Book and Ohio EPA.
- Confirm whether any emergency generator needs an Ohio EPA permit or exemption.
- Apply standard construction dust controls.
Agencies
- Ohio EPA
- USEPA
Cost and impact
- Impact
- None given.
- Potential cost level
- N/A
- Why
Abstaining; no cost exposure can be assessed without attainment status.
Impact: C = cost, S = schedule. Potential cost level: L, L-M, M, M-H, H (relative to a utility-scale solar budget).
Comments
No air quality review is included in the data room. Attainment status for Carroll County and any air permit or exemption need (e.g., emergency generators with the battery storage) are not addressed. Review of the USEPA Green Book and Ohio EPA requirements would settle it.
