49 CFR 192 vs 195: Key Differences for Pipeline Compliance

49 CFR Part 192 covers transportation of natural and other gas by pipeline. Part 195 covers hazardous liquids. Operators sometimes run both — and must keep procedure libraries, integrity programs, and reporting logic correctly separated.

Key differences show up in integrity management, reporting thresholds, and operational controls. Treating “pipeline compliance” as one undifferentiated pile of PDFs is how the wrong procedure gets cited in the wrong context.

For multi-commodity or multi-entity operators, workspace design matters: manuals, stations, and AI context should reflect which Part (and which state overlay) applies to each asset.

Training and field forms should also track the split. A gas patrol checklist is not a liquid integrity work order by another name.

When evaluating software, ask how it scopes answers and templates by regulatory domain — not just by keyword search across a single mega-library.
