Under the Clean Air Act, who must be notified of uncontrolled discharges of oil or petroleum products?

The correct answer is the Coast Guard, as they are the federal agency that handles the response to oil spills in navigable waters under the Clean Water Act, which complements the Clean Air Act in addressing environmental protection issues. The Coast Guard is responsible for ensuring that any uncontrolled discharges of oil or petroleum products are managed properly, particularly those that could affect marine environments and public safety.

In contexts of spill response, the Coast Guard plays a critical role in coordinating efforts and providing necessary resources in case of significant oil-related incidents, particularly those that might occur in maritime areas. While other agencies, such as the Environmental Protection Agency and state environmental agencies, might be involved in the broader regulatory oversight or environmental assessments, the initial notification and response protocol for oil spills specifically falls within the jurisdiction of the Coast Guard.
