There are a number of decision points in crafting local legislation to ban plastic bags.  First is the thickness of the bag.  Some municipalities target bags over 1.5 mil thick; others target bags under 2.5, or 3.0, or even 4.0 mil thick.  Another is to determine which businesses are impacted, all retail establishments, or just businesses over a certain size (i.e. big box and grocery stores).  Many plastic bag bans also specify guidelines for paper bags.  Although no municipality in Massachusetts currently charges a mandatory levy for bags, cities in other states have imposed a 5 or 10 cent fee per bag in lieu of a total ban.  There are also the question of who will enforce the ban, and what fines will be levied for non-compliance.  Municipalities in Massachusetts and elsewhere have addressed these matters differently.  It is worth comparing legislation from several locations to determine what works best for your community.
