History

health and reduce emissions. In 2015, the EPA increased the ground-level ozone standards 
to 70 parts per billion(ppb) (EPA). This ozone standard currently designates Yuma and 
Phoenix-Mesa areas as nonattainment (ADEQ).

Arizona and asks the EPA to implement a state plan to achieve and maintain a relevant 
air standard. (Sec. 1)
