Pipeline and Hazardous Materials Safety Administration

<h2 id="history">History</h2>
<p>Prior to 2005 the <a href="/facts/U.S._Department_of_Transportation/qgNCJ1tF">U.S. Department of Transportation</a> had no focused research organization and no separately operating administration for pipeline safety and <a href="/facts/Hazardous_material/mfe6Yv43">hazardous materials</a> <a href="/facts/Transportation_safety_in_the_United_States/E5Mfkzbk">transportation safety in the United States</a>. The <a href="/facts/Norman_Y._Mineta/rhr3SpWp">Norman Y. Mineta</a> Research and Special Programs Improvement Act of 2004 provided these, with an opportunity to establish mode government budget and information practices in support of then <a href="/facts/George_W._Bush/mYSgM515">president George Bush</a>'s "Management Agenda" initiatives.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> Prior to the Special Programs Act of 2004, PHMSA's hazmat and pipeline safety programs were housed within the Transportation Department's Research and Special Programs Administration, known as RSPA.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a>
</p>
<h2 id="office-of-hazardous-materials-safety">Office of Hazardous Materials Safety</h2>
<p>The Office of Hazardous Materials Safety is responsible for the oversight of the safe transportation of <a href="/facts/Dangerous_goods/mfe6Yv43">hazardous materials</a> by air, rail, highway, and vessel. More than 3.3 billion tons of hazardous materials valued at more than $1.9 trillion are transported annually by air, highway, rail, and vessel across the United States. On average, more than 1.2 million hazardous materials shipments occur every day. This includes everything from <a href="/facts/Nuclear_waste/MjYh5tlu">nuclear waste</a> to lithium-ion batteries, to explosives used in excavation, mining, and energy production. The program establishes policy, standards and regulations for classifying, packaging, hazard communication, handling, training and transporting hazardous materials via air, highway, rail and vessel. The program uses inspection, enforcement, outreach and incident analysis in efforts to reduce incidents, minimize fatalities and injuries, mitigate the consequences of incidents that occur, train and prepare first responders, and enhance safety.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a>
</p>
<h2 id="office-of-pipeline-safety">Office of Pipeline Safety</h2>

<p>As of 2022, the Office of Pipeline Safety regulated an expansive network of about 3.4 million miles of <a href="/facts/Natural_gas_pipeline_system_in_the_United_States/keSKGX3n">natural gas pipeline system in the United States</a> and its hazardous liquid pipelines.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a><a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> This includes 229,000 miles of hazardous liquid pipelines, 302,000 miles of gas transmission pipelines, 2,284,000 miles of gas distribution mains and services, and 17,000 miles of gas-gathering pipelines.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> PHMSA’s pipeline safety program promotes the safe delivery of energy products to market in a manner that protects people, property, and the environment. 
</p><p>The Office of Pipeline Safety is headquartered in Washington, D.C., with eight field offices located in <a href="/facts/West_Trenton%2c_New_Jersey/N3hqHs7a">West Trenton, New Jersey</a>; <a href="/facts/Atlanta%2c_GA/8hPVGb78">Atlanta, GA</a>; <a href="/facts/Kansas_City%2c_Missouri/N8GxbWWR">Kansas City, Missouri</a>; <a href="/facts/Houston%2c_Texas/1v8AwQUN">Houston, Texas</a>; <a href="/facts/Lakewood%2c_Colorado/n5GhcgVF">Lakewood, Colorado</a>; <a href="/facts/Des_Plaines%2c_Illinois/A3ty6UWd">Des Plaines, Illinois</a>; <a href="/facts/Ontario%2c_California/bKHFDXIU">Ontario, California</a>; and <a href="/facts/Anchorage%2c_Alaska/PwmVdJex">Anchorage, Alaska</a>. PHMSA also operates a national training center and accident investigation office located in <a href="/facts/Oklahoma_City/o7P8l8Cd">Oklahoma City</a>.
</p><p>In 2022, the PMHSA admitted that CO2 pipelines were underregulated and announced "new measures to strengthen its safety oversight".<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a>
