Final answer:
To report spills and storage of oil or oil products, the correct agency is the Environmental Protection Agency (EPA), in line with the SPCC Rule.
Step-by-step explanation:
When dealing with spills and storage of oil or oil products, the appropriate agency to report to is the Environmental Protection Agency (EPA). This is in accordance with the Spill Prevention, Control, and Countermeasure (SPCC) Rule, which is a part of the EPA's oil spill prevention program. The SPCC rule applies to all facilities that store, handle, process, or use oil and oil products, with specific requirements for facilities that store large quantities of oil. In the event of a spill, it's crucial to inform the EPA, as they are responsible for overseeing the compliance with environmental regulations designed to prevent oil spills and ensure containment and countermeasures are in place to protect navigable waters and adjoining shorelines.
