What the Commission did
- Notice of Violation 15
From the Commission's inspection and violation files, covering Aug 1 2015 to Aug 7 2026. The two are separate files with no key between them, so the violations here are not a subset of the 12 inspections that found this operator out of compliance — they are counted from their own file. 3 of the violations were still uncorrected when the inspector returned.
The Railroad Commission's docket file published 2025-02-05 names no case against this operator. That is what the file holds. It is not a statement that none exists.
Leases
Every lease is a page of its own: the monthly volumes the state published, multiplied by the monthly price. Value is lifetime, from Jan 1993.
