AUGUSTA, Maine (AP) Maine legislators have passed a bill banning the intentional release of many balloons.

The measure now awaits the signature of Gov. Janet Mills.

The Sun Journal reports that the bill would create a fine for anyone who releases a large number of balloons on purpose out of concern for their impact on the environment. First-time offenders who release between 16 and 24 balloons would be fined between $100 and $500.

The proposal would not punish someone who accidentally lets go of a single balloon. It also exempts the release of balloons for scientific or meteorological purposes.
