Oregon's Department of Environmental Quality has also ordered a ban on self-service gasoline due to inexperienced pumpers being a significant source of groundwater and air pollution. Oregon's state fire marshal has also ordered a ban on self-service gasoline. Today, these states enforce the law because of the rapid increase of drive-offs[citation needed], where people fill up their car and drive away without paying for gas. In 1982, Oregon voters rejected a ballot measure sponsored by the service station owners, which would have legalized self-service gas.
