The EPA Helicopter is owned by the Environmental Protection Agency. The EPA used it to enforce its order that the Simpsons care for the Screamapillar. When Homer believes that he has accidentally killed the Screamapillar, he buries it both to avoid trouble and to be rid of it. Just as he finishes, however, the EPA Scientist arrives in the copter, catching him red-handed. In The Simpsons Movie, EPA Helicopters lower the Dome.
