The Work, in Your Words.

Three Part 195 sections alone account for more federal cases than all of Part 192 outside the manual. Each is a screen in X3.

The procedural manual

The 195.402 manual for normal operations, maintenance, abnormal operations and emergencies, matched section by section in Procedure Coverage.

Integrity management in HCAs

Segments that could affect a high consequence area, the assessment plan, ILI runs, anomaly response and preventive and mitigative measures (195.452).

Control room management

Roles, shift handover, fatigue, alarm management and SCADA verification under 195.446.

Valves, overpressure and leak detection

Valve maintenance (195.420), overpressure safety devices (195.428), leak detection (195.444) and atmospheric corrosion inspections (195.583).

What PHMSA cites

The Part 195 Sections Cited Most.

239 of the 577 federal enforcement cases opened from 2023 to 2026 cite at least one Part 195 section. These are the sections cited in the most cases, and where X3 keeps the work each one asks for.
