An oil spill classified as 'Major' is defined as one that involves over 10,000 gallons of oil. This classification is crucial because the severity of an oil spill increases with the volume released, and spills above this threshold can have significant environmental impacts, potentially affecting marine life, ecosystems, and local economies.

Spills of this magnitude often require a coordinated response from various agencies and organizations, including federal, state, and local resources, to manage containment, cleanup, and mitigation efforts effectively. Understanding the classification helps responders prioritize resources and response strategies for effective management of the incident.

In contrast, spills less than this threshold would typically be categorized as minor, with responses being more localized and manageable. This distinction helps in defining the scale of resources and types of response actions necessary for incidents of varying severity.
