According to the DOT, how is a small spill defined?

A small spill, according to the Department of Transportation (DOT), is defined as a leaking container smaller than 55 gallons. This definition is important for understanding how to manage and respond to spills effectively. The threshold of 55 gallons helps ensure that response measures are appropriate for the scale of the spill and allows for a distinction between small and large spills, which can significantly influence the type of response required, regulatory requirements, and potentially the logistics involved in containment and cleanup. Recognizing a spill as small allows personnel to mobilize appropriate resources without escalating to higher levels of emergency management unless necessary.
