Which regulatory body oversees gas utility operations?

The Federal Energy Regulatory Commission (FERC) is the regulatory body that oversees gas utility operations, which includes the interstate aspects of natural gas transmission and rates. FERC ensures that natural gas companies provide their services at just and reasonable rates, and it regulates the wholesale sale of natural gas in interstate commerce. Additionally, FERC is responsible for implementing regulations that promote the development of energy markets and maintain the reliability of the energy infrastructure.

In contrast, the Environmental Protection Agency (EPA) focuses primarily on environmental issues and enforcing regulations to protect public health and the environment but does not directly regulate gas utility operations. Similarly, the Occupational Safety and Health Administration (OSHA) is concerned with workplace safety and health regulations but does not oversee gas utilities specifically or their operational practices. The Nuclear Regulatory Commission (NRC) oversees the safety and regulation of nuclear power plants and materials rather than natural gas operations. Therefore, FERC is the correct answer as it is specifically tasked with regulating gas utility operations.
