The ban on single-use, carryout plastic bags is now being enforced in Santa Monica, Calif. The ban became official March 1 but Sept. 1 marked the enforcement date.
All 1,875 retail establishments are prohibited from providing lightweight, single-use plastic carryout bags to customers at the point of sale, according to the City of Santa Monica.
Any plastic bag less than 2.25 mil thick is banned, including bio-based plastic bags made from plant sources such as corn.
Long Beach, Calif., also recently banned plastic bags for some retailers and others.
It is set to go into effect Jan. 1, 2012.
The Long Beach City Council voted to ban plastic bags and enact a 10-cents-per-bag charge for recyclable paper bags in May 2011, according to the L.A. Times.
The first phase—the portion effective Aug. 1—applies to large retailers. The second phase, which extends the ordinance to smaller stores—such as neighborhood markets, pharmacies, sandwich and coffee shops and liquor stores—will go into effect Jan. 1, 2012. City officials said they hoped the ban would inspire other Southern California cities to enact similar ordinances.
