Due to a consolidation of data sources on these pages, the county-level mileage breakdowns are no longer available on this tab.

For information pertaining to the geographic locations of gas transmission and hazardous liquid pipelines, please go to PHMSA's National Pipeline Mapping System (NPMS) public viewer in order to locate these pipelines on actual county maps.

A user manual is available, along with a video tutorial. Note that gas gathering and gas distribution lines are not available on these maps.

Notes

  1. The miles of gas distribution service lines (the connection between the distribution line and the end user) are not included in the Gas distribution mileage. The total number of such services is provided.
  2. The costs for incidents in 2013 and prior are presented in 2013 dollars. Cost of Gas lost is indexed via the Energy Information Administration, Natural Gas City Gate Prices. All other costs are adjusted via the Bureau of Economic Analysis, Government Printing Office inflation values.
  3. For years 2002 and later, property damage is estimated as the sum of all public and private costs reported in the 30-day incident report. For years prior to 2002, accident report forms did not include a breakdown of public and private costs so property damage for these years is the reported total property damage field in the report.
  4. Starting Sept 2013, this column displays "volume released unintentionally" for all years after 2009. Before Sept 2013, the column displayed the sum of "volume released unintentionally" and "volume released intentionally" for all years after 2009.
  5. Net Barrels Lost applies only to Liquid incidents and is the difference between Gross Barrels Spilled and Barrels Recovered.
  6. Gas Distribution incidents where fire/explosion was the primary cause of failure, such as a house fire that subsequently resulted in - but was not caused by - a distribution line failure are excluded from 2004 onward. This exclusion has not been applied in years prior to 2004 due to difficulty in identifying these types of events with the older report formats.
