Key Takeaways
- Use this checklist as a pre-inspection self-audit tool — identify gaps before the inspector does.
- Each section maps to specific 49 CFR Part 192 requirements — citation references are included to help locate the underlying regulations.
- Pay particular attention to calibration records, OQ documentation, and written procedures — these are consistently the top three citation areas in gas distribution inspections.
- For each gap you find, document a corrective action plan with an owner and a target closure date.
- Inspect your record retrieval capability, not just record existence — slow retrieval looks like missing records to an inspector.
Section 1: Written Operations & Maintenance Procedures
Your O&M manual is typically one of the first things a PHMSA inspector reviews. Verify the following:
- Written O&M procedures exist for all required operational activities (§192.605)
- Procedures are current — reviewed and updated at intervals not exceeding 15 months
- Procedures are accessible to personnel in the field — not just in an office binder
- Emergency procedures are current and include all required response scenarios (§192.615)
- Distribution integrity management plan is current and approved by management
- All procedures reference applicable standards and regulatory citations
Section 2: Calibration Records
Calibration record deficiencies are cited in the majority of gas distribution inspections. Verify:
- Instrument inventory is current — all instruments in safety-critical service are identified and registered
- Calibration records exist for all instruments in the inventory with no gaps
- Records contain as-found and as-left readings, not just 'pass/fail' notations
- NIST traceability chain is documented — reference standard certificates are current
- No instruments are past their calibration interval without documented out-of-service or interval extension justification
- Calibration records are retrievable by instrument, date, and technician within a reasonable time
- Retention policy is defined and calibration records are maintained for required periods
Section 3: Operator Qualification Program
OQ is a primary inspection focus for distribution operators. Verify:
- Written OQ program exists and has been reviewed within the past year
- Covered task list is current and comprehensive — all safety-sensitive work activities are identified
- Individual qualification records exist for all employees performing covered tasks
- Qualification records document the evaluation method used, not just course completion
- No employees are performing covered tasks for which they are not documented as qualified
- Contractor OQ verification records are maintained — the operator can verify contractor personnel qualification
- Qualification renewal process exists for time-limited qualifications; no expired qualifications in active use
Section 4: Corrosion Control Records
Cathodic protection and corrosion monitoring records are frequently reviewed in transmission and distribution inspections:
- Annual cathodic protection surveys conducted and documented (§192.465)
- Rectifier and other impressed current system operating records current (§192.473)
- Remediation actions on identified corrosion documented and tracked to closure
- Corrosion control survey instrument calibration records current
- Atmospheric corrosion inspection records current for exposed pipe segments
Section 5: Leak Survey Records
Leak survey programs are a core distribution system safety requirement:
- Leak survey schedule is current and completed within required intervals by main type and business district classification
- Leak survey instrument calibration records are current and complete
- Leak reports documented for all identified leaks with classification, priority, and resolution tracking
- Grade 1 and Grade 2 leaks repaired or scheduled within required timeframes
- Survey route maps or GPS records available to document survey coverage
Section 6: Emergency Response
Emergency response program readiness is verified in every inspection:
- Emergency response plan is current — reviewed within the past 15 months
- Contact lists in the emergency plan are current (emergency contacts, utility notifications, mutual aid)
- Required emergency response drills conducted and documented within required intervals
- Personnel trained and familiar with emergency response procedures
- Emergency shutdown valve locations documented and valves exercised per required intervals
Section 7: Recordkeeping & Retrieval Capability
Compliance record organization and retrieval are evaluated in every inspection — often informally, through how quickly your team responds to documentation requests:
- All required records have a designated storage location and responsible custodian
- Retention schedules are defined for all record types
- Records can be retrieved by date, asset, or category within 30 minutes of a request
- Prior inspection findings and corrective action status are documented and accessible
- No records are stored exclusively on personal employee devices or personal email accounts
Expert Note: Compliance record retrieval speed is an indirect indicator of your compliance management maturity. Operators who produce well-organized, complete records quickly create a favorable inspection environment. Operators who struggle to find records invite a more comprehensive examination.
