UT HB0591

Abrogates common law civil rights of action for public and private nuisances in Utah, with an exception allowing the attorney general to bring such actions when there is substantial ongoing harm to a significant number of citizens

Redefines "public nuisance" as conditions that unlawfully interfere with public rights by endangering community safety or obstructing public passages, explicitly excluding lawful activities, government-authorized actions, legal product manufacturing/marketing, and firearms-related activities

Redefines "private nuisance" as conditions arising from real property use that are injurious to health/safety or obstruct neighboring property enjoyment, including drug houses, gambling, prostitution, gang activity, and party houses that create disturbances

Limits remedies in government-brought public nuisance actions to injunctive relief and abatement resources, prohibiting damages awards; private parties can only bring public nuisance claims if they prove "special injury" different in kind from general public harm

Creates specific defenses for agricultural operations, manufacturing facilities operating over three years, critical infrastructure materials operations, and shooting ranges against nuisance claims, and requires the attorney general to report to the Judiciary Interim Committee every four years on use of the common law nuisance exception
