The Assembly has advanced a bill extending a series of fees to pay for programs aimed at improving air quality. Democratic Assemblyman Henry Perea of Fresno said his legislation is needed to continue reducing air pollution. He says more than 90 percent of Californians live in counties with unhealthy air during some parts of the year.

Fees to be extended under AB8 include ones on new tires and vehicle and boat registrations. Those fees are scheduled to expire by 2016 but would be extended until 2024 under Perea's bill.
