EVIDENCE NOTE

What the public record says

A machine-extracted candidate of equipment groups and permit limits stated in Virginia DEQ permit 74114-3, with one-based PDF page citations. Permitted terms do not establish actual operation or emissions.

Summary fields cite p. 1 ↗, p. 3 ↗.

What this record does not establish

The source confirms the document and its stated fields. This profile does not infer actual emissions, compliance history, operating status, facility capacity or environmental impact where those facts are not established by the cited document.

How to read the status

Issued means the agency granted the permit subject to its conditions. It does not mean every permitted unit is operating, that maximum permitted emissions occur, or that later amendments do not exist.

MACHINE-EXTRACTED CANDIDATE

kept separate from actual use.

These page-cited rows are machine-extracted and still require a second manual review. Verify every reused value against the linked official PDF. Page numbers refer to the one-based position in the linked PDF. Blank values are not zero.

Permitted equipment

5 document-defined equipment groups. Counts and per-unit ratings are transcribed; combined capacity is not calculated.

QA NOTES

Ambiguity stays visible

Machine-extracted candidate. Verify every reused value against the cited official PDF page.
Verify table column grouping and any alternative models.
Confirm whether the limit is per unit, combined, or limited to testing/maintenance.
Confirm multi-row and merged-column header association.
Older-PDF text fallback; verify row and unit alignment.
