The bill prohibits any public body in New Mexico from enacting or enforcing laws, ordinances, policies, or rules that restrict the use of plastic grocery bags by retail grocers. It defines key terms such as "public body," "local government," and "plastic grocery bag," clarifying that a plastic grocery bag is one provided by a retailer for transporting food or goods, made from synthetic materials or biologically based polymers.

This legislation aims to ensure that retail grocers can continue to use plastic grocery bags without interference from local or state regulations. By establishing this prohibition, the bill seeks to standardize the use of plastic bags across the state, preventing local governments from implementing their own restrictions.
