Which agency regulates natural gas pipelines in the United States?

The correct answer is the Pipeline and Hazardous Materials Safety Administration (PHMSA), which is responsible for ensuring the safety of transportation systems for hazardous materials, including natural gas pipelines. PHMSA develops and enforces regulations that govern the design, construction, operation, and maintenance of pipeline facilities. This agency also provides oversight to ensure that pipeline operators maintain safety standards and respond effectively to incidents.

In the context of natural gas pipelines, PHMSA plays a crucial role in protecting public safety and the environment, making it the appropriate agency for this responsibility. Their regulations help minimize the risks associated with the transportation of natural gas and other hazardous materials.

While the Federal Energy Regulatory Commission (FERC) is involved in the oversight of the interstate transmission of electricity, natural gas, and oil, it does not directly regulate the safety aspects of natural gas pipelines. The Environmental Protection Agency (EPA) primarily focuses on environmental protection and does not manage pipeline safety. The Department of Energy (DOE) has roles related to energy production and regulation but is not specifically tasked with pipeline safety regulations.
