Spill response refers to the methods and measures used to prevent hazardous materials, petroleum products or common chemicals from endangering public health or the environment if they reach waterways. Spill response and prevention practices can help to prevent spills from happening and can minimize impacts when a spill does occur. A key practice is creating and implementing a spill response and prevention plan, which should clearly state how to prevent spills, stop the source of a spill, how to contain and clean up a spill, how to dispose of contaminated materials, and how to train personnel to prevent and control future spills1.
