The assessor's 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.

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

2What the record shows

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.

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.
