Utah Code §10-9a-528 preempts Salt Lake City from banning polystyrene foam takeout containers. Restaurants may voluntarily switch to alternative materials, but no local mandate exists. Many SLC restaurants choose compostable or recyclable packaging.
Utah's 2019 auxiliary container preemption statute, codified at §10-9a-528, blocks Salt Lake City from prohibiting expanded polystyrene foam clamshells, cups, and trays used in restaurant takeout. While many west-coast cities like Portland and San Francisco enacted EPS bans, SLC cannot. Salt Lake City does encourage voluntary phaseout through its sustainability programs and 1.5 Climate Plan goals. Local restaurants and grocers may opt for paper, fiber, or compostable alternatives. The Utah Beverage Container Recycling industry has lobbied to maintain preemption. Federal agencies and university campuses may set their own foam policies independently.
No local violations exist for foam container use because state law preempts municipal regulation. Restaurants face no city penalty for using polystyrene takeout packaging.
