EVIDENCE NOTE
What the public record says
A manually verified transcription of equipment groups and permit limits stated in Virginia DEQ permit 74063-5, with one-based PDF page citations. Permitted terms do not establish actual operation or emissions.
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.
VERIFIED PERMIT TERMS
Equipment and limits, kept separate from actual use.
This is a conservative transcription of reviewed permit sections, not an exhaustive legal digest. Page numbers refer to the one-based position in the linked PDF. Blank values are not zero.
Permitted equipment
10 document-defined equipment groups. Counts and per-unit ratings are transcribed; combined capacity is not calculated.
