SB 146 Utah Senate · 2026 General Session

Industrial Byproduct Amendments

SB 146 modifies Utah's rules for reusing industrial byproducts like construction debris, ash, or mineral residues. It allows any project (not just public projects) to use an approved byproduct if the Waste Management Division director approves its reuse application. The bill exempts approved byproducts from requiring health risk assessments, ecological studies, or environmental covenants. It repeals an older restriction that limited reuse to public projects and updates definitions for clarity. This change affects businesses and contractors seeking to reuse industrial waste materials in construction or infrastructure projects.
