America’s got a lot in the pipeline. More specifically, the United States hosts 2.7 million miles of pipelines that transport oil, natural gas, and other fossil fuels to create energy. These fuels are hazardous and potentially explosive, and in a March report the U.S. Congressional Research Service (CRS) argued that they are making pipeline security a national security issue.

“Ongoing threats against the nation’s natural gas, oil, and refined product pipelines have heightened concerns about the security risks,” wrote CRS in its report, Pipeline Security: Homeland Security Issues in the 116th Congress.
