Launch edition
Index architecture is live. Verified aggregates follow retained source snapshots.
The initial edition publishes the shared vocabulary, source routes and system boundaries first. Counts and rates will be added only after PipeMag can retain the file, checksum it, map its fields and reproduce the displayed result.
| View | Source system | What remains distinct |
|---|---|---|
| Gas distribution | PHMSA incident data, 2010–present | Incident definition and annual report fields |
| Transmission & gathering | PHMSA incident data, 2010–present | Transmission, gathering and facility scope |
| Hazardous liquid | PHMSA accident data, 2010–present | Accident threshold and release fields |
| LNG | PHMSA incident data, 2011–present | Facility context is not a mileage proxy |
What readers can verify now
PHMSA explains that incident files contain a data file and a field-description file. PipeMag will retain both, keep reported and normalized values side by side, and display a link to the originating official source. The methodology records the rules before numbers are published.
Use the failure-cause guide to understand why cause labels cannot always be pooled. For background on denominators, read U.S. pipeline mileage.
Official dataset collection is required before PipeMag displays an aggregate. This edition intentionally shows no incident total, rate, ranking or selected case match.
