South Dakota Plastic Bag Preemption Framework

Under SDCL Title 9 Chapter 32 and SDCL 9-29 governing municipal powers, cities may regulate solid waste collection but lack express authority to ban auxiliary containers like plastic bags. Although South Dakota has not passed an explicit auxiliary container preemption statute like neighboring states, no city has enacted a plastic bag ban, and local ordinances regulating retail packaging would face challenges under Dillon's Rule limiting municipal authority to expressly granted powers.

If a city enacted a plastic bag ban, retailers could challenge it as ultra vires; courts would assess authority under Dillon's Rule and SDCL 9-32 solid waste provisions.
