Antifreeze and petroleum product enforcement.

This bill modifies Wyoming's enforcement procedures for antifreeze and petroleum products. It requires the state director to periodically collect samples from storage tanks and dispensing devices at retail facilities, mandating at least one annual sample per tank. The director must also ensure samples are taken after allowing at least one gallon to flow from dispensers. These changes apply to facilities handling these products and take effect July 1, 2019. The bill updates sampling protocols without altering product standards or creating new regulations.
