EVIDENCE NOTE
What the public record says
A machine-extracted candidate of equipment groups and permit limits stated in Virginia DEQ permit 74162-5, 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.
MACHINE-EXTRACTED CANDIDATE
Equipment and limits, 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
6 document-defined equipment groups. Counts and per-unit ratings are transcribed; combined capacity is not calculated.
