Okay kiddo, imagine if you accidentally spilled your juice and it made a big mess on the floor. You would want someone to come and help clean it up, right? Well, sometimes grown-ups make big messes too, like when they spill oil or other dangerous stuff.
That's where the National Oil and Hazardous Substances Contingency Plan comes in. It's like a big book of rules that grown-ups have made to help clean up these big messes.
If someone spills something dangerous, they have to tell the grown-ups in charge, who will then follow the rules in the book to figure out how to clean it up. The book tells them what kind of equipment to use, how to keep people safe, and who to call for extra help if they need it.
It's really important to have this plan, so that we can keep our environment clean and safe for everyone to enjoy.
