The L.A. Times reports:

The ordinance, which by 2012 will cover 1,000 stores in unincorporated areas, also will require supermarkets and pharmacies to levy a 10-cent surcharge per paper bag. Proponents see it as a model for California.

The Los Angeles County Board of Supervisors voted Tuesday to ban plastic grocery  bags in areas of the county under its jurisdiction, endorsing a broadly worded measure that proponents hope could become a model for California.

The ban, which goes beyond ordinances adopted in Malibu and San Francisco, most directly affects 1.1 million people who live outside the county's incorporated cities. But anyone shopping at stores in such areas would encounter the new rules.
