Pipeline accidents in North America: the shocking statistic you need to know
Over the past 20 years, North America has recorded more than 9,000 significant pipeline incidents, resulting in 548 deaths, 2,576 injuries, and over $8.5 billion in financial damages according to federal data from the Pipeline and Hazardous Materials Safety Administration (PHMSA). Despite industry claims of improving safety, liquids pipeline incidents decreased only 23% over the last five years, with 87 fewer incidents in 2023 compared to 2019.
Recent Pipeline Accident Statistics and Trends
The 2023 safety report reveals that while overall liquids pipeline incidents declined, incidents impacting people or the environment decreased by only 7% over the five-year period. PHMSA has been collecting pipeline incident reports since 1970, creating the most comprehensive historical safety database available for North American pipeline operations.
- Liquids pipeline incidents are down 23% over the last 5 years
- Incidents impacting people or the environment decreased 7% over the last 5 years
- Incorrect operation incidents causing human/environmental impact dropped 45% since 2019
- Equipment failure incidents causing human/environmental impact decreased 50% from 2019 to 2023
- Between 2012-2020, spill costs totaled $2.64 billion but operators paid only 3.78% ($101 million)
Deadliest Pipeline Accidents in North American History
The San Bruno catastrophe on September 9, 2010, remains one of the most devastating pipeline accidents, killing eight people and injuring 51 when a natural gas transmission pipeline exploded in California. The 2010 San Bruno explosion alone accounted for a significant portion of the 17 total deaths and 86 injuries from transmission pipeline explosions between 2010-2016.
From 2015 to 2017 alone, natural gas pipelines in the United States caused 12 deaths and 10 injuries, demonstrating that pipeline explosions continue to pose serious risks to communities. These explosions also cause millions of dollars in property damage and force widespread evacuations in affected neighborhoods.
- September 9, 2010: San Bruno, California - 8 killed, 51 injured, massive property destruction
- 2010-2016 period: 35 explosions and 32 ignitions at transmission pipelines nationwide
- 2015-2017: 12 deaths and 10 injuries from natural gas pipeline explosions
- Over 20 years: 548 total deaths and 2,576 injuries from all pipeline types
- 2023: 87 fewer liquids pipeline incidents compared to 2019 baseline
Pipeline Accident Data by Type and Cause
Federal tracking distinguishes between three major pipeline categories: gas transmission, gas distribution, and hazardous liquid pipelines, each with distinct risk profiles and incident patterns. Hazardous liquid pipelines include those delivering crude oil, refined products like gasoline and diesel, natural gas liquids such as propane, and carbon dioxide.
| Pipeline Type | Incident Trend (5 Years) | Primary Causes | Human Impact |
|---|---|---|---|
| Liquids Pipelines | Down 23% | Equipment failure, corrosion | 7% decrease in human/environmental impact |
| Gas Transmission | 35 explosions (2010-2016) | Equipment failure, material defects | 17 deaths, 86 injuries (2010-2016) |
| Gas Distribution | 32 ignitions (2010-2016) | Locating issues, third-party damage | 12 deaths, 10 injuries (2015-2017) |
| All Types (20 Years) | 9,000+ significant incidents | Corrosion, equipment, operation | 548 deaths, 2,576 injuries |
Geographic Distribution of Pipeline Accidents
The spread of accidents since 1986 is substantial across North America, with Texas consistently showing the highest concentration of pipeline incidents in recent PHMSA data. In 2025 alone, Texas accounted for numerous reported incidents including equipment failures at Plains Pipeline, corrosion failures, and locating issues affecting Atmos Energy Corporation.
Between 2012 and 2020, hazardous liquid spills on Native Lands showed an increase in monthly average numbers, raising environmental justice concerns for indigenous communities. The data can be filtered by date, state, county, and operator through PHMSA's machine-readable formats.
Root Causes of Pipeline Failures
PHMSA incident data from 2025 shows equipment failure remains the leading cause of pipeline accidents, followed by corrosion failure and locating issues. The industry's 2023 performance report highlights that incorrect operation incidents decreased 45% since 2019, while equipment failure incidents causing human or environmental impact dropped 50%.
Corrosion failure continues to threaten pipeline integrity, with recent incidents in Texas showing damages ranging from $1,200 to over $166,000 for single events. The reporting regulations have changed several times since 1970, affecting how incidents are classified and tracked over time.
Regulatory Framework and Safety Improvements
The Pipeline and Hazardous Materials Safety Administration (PHMSA) collects incident reports under regulations that require reporting accidents with gross loss greater than or equal to 50 barrels, any fatality or injury, or total costs greater than or equal to $50,000. Beginning in 2002, reporting thresholds were tightened to include only significant incidents meeting these criteria.
Industry groups like the Liquid Energy Pipeline Association (LEPA) and American Petroleum Institute (API) jointly released the 2023 Performance Report showing measurable safety improvements. The 2023-2025 Pipeline Excellence Strategic Plan outlines continued focus on reducing incidents impacting people or the environment.
Environmental and Community Impact
Since 1995, the overall amount of oil released to the environment has increased each year, contradicting some industry safety claims. Pipeline spills impact both human communities and ecosystems, with hazards ranging from explosions to groundwater contamination.
The probability of a spill from rail transport is greater on a per-barrel-mile basis, yet pipelines spill more both by sheer volume and on a per-ton-mile basis when comparing transportation methods. This data fuels ongoing debates about whether fossil fuels should be transported by pipeline versus alternative methods.
Accessing Pipeline Safety Data
Researchers and concerned citizens can access machine-readable pipeline incident data from PHMSA's official website, including distribution, transmission, gathering, LNG, and liquid accident datasets. The Pipeline Safety Trust maintains user-friendly incident data compilations covering hazardous liquid, natural gas transmission, and natural gas distribution pipelines from 1986 onward.
Interactive dashboards now allow filtering by program, year, state, operator, cause, consequences, and damage amounts, with 300 total incidents tracked in 2025 alone showing a 37.4% year-over-year decrease. This transparency enables better public accountability and informed decision-making about pipeline infrastructure investments.
Conclusion: The Path Forward for Pipeline Safety
The shocking statistic remains clear: 548 deaths and 2,576 injuries over two decades demonstrate that pipeline accidents continue posing serious risks despite safety improvements. While the 23% decrease in liquids pipeline incidents shows progress, the 7% reduction in human/environmental impact suggests more work remains.
Communities near pipeline infrastructure must remain vigilant, as equipment failure and corrosion continue causing preventable accidents across North America. The $8.5 billion in damages over 20 years represents not just economic loss but irreparable harm to families and communities affected by pipeline explosions.
