EVIDENCE NOTE

What the public record says

A machine-extracted candidate of equipment groups and permit limits stated in Virginia DEQ permit 74079-5, with one-based PDF page citations. Permitted terms do not establish actual operation or emissions.

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.
