Which regulatory body oversees aerial surveillance for pipelines in the United States?

The Federal Energy Regulatory Commission (FERC) is the correct answer because it is primarily responsible for regulating aspects of the transmission of energy resources, including the oversight of pipeline safety and integrity. Part of this responsibility encompasses ensuring that operators have proper surveillance and monitoring practices for pipelines to minimize risks and enhance safety.

FERC sets guidelines and regulations that pipeline operators must follow, which can include measures for aerial surveillance to effectively monitor pipeline conditions and detect potential issues. This focus on safety and oversight aligns closely with FERC's mission to ensure the reliability of energy services.

While the other agencies mentioned have important roles in different aspects of pipeline operations or air travel, they do not directly oversee aerial surveillance for pipelines. The FAA primarily regulates aviation standards and safety, the EPA focuses on environmental protection and regulations, and the TSA is concerned with transportation security rather than pipeline oversight. Therefore, FERC's specific mandate regarding pipeline safety makes it the appropriate regulatory body for overseeing aerial surveillance efforts related to pipelines in the U.S.
