Which agency is likely responsible for regulating hazardous materials incidents?

The Environmental Protection Agency (EPA) is the agency primarily responsible for regulating hazardous materials incidents. The EPA's mission focuses on protecting human health and the environment, which includes enforcing regulations regarding the management, disposal, and remediation of hazardous substances. This agency develops and enforces laws to control pollutants and hazardous waste, ensuring that hazardous materials are handled safely and that the impact on the environment and public health is minimized.

In addition to its regulatory role, the EPA provides guidance and support for local agencies and responders when hazardous materials incidents occur. This involves monitoring, reporting, and responding to spills, leaks, and other hazardous material emergencies.

While local fire departments, OSHA, and the FBI have roles in emergency response, workplace safety, and law enforcement, respectively, their responsibilities do not specifically encompass the comprehensive regulation of hazardous materials incidents as the EPA does. The local fire department may respond to incidents and handle immediate emergencies, OSHA oversees workplace safety concerning hazardous substances, and the FBI typically handles criminal activities rather than environmental regulation.
