The duties of which department include the adminstration of oil and gas pipelines?

The duties related to the administration of oil and gas pipelines typically fall under the jurisdiction of the Department of Transportation (DOT) in the United States, specifically through the Pipeline and Hazardous Materials Safety Administration (PHMSA). This department is responsible for ensuring the safe and efficient transportation of oil and gas through pipelines by enforcing regulations, conducting inspections, and overseeing safety practices. Additionally, state regulatory agencies may also play a role in the oversight of pipeline operations within their jurisdictions.
