A bill for an act relating to the prohibition of geoengineering activities, providing penalties, and including effective date provisions.

This bill prohibits activities like cloud seeding and weather modification that deliberately release substances into the atmosphere, affecting anyone conducting such practices in Iowa. It defines "polluting atmospheric activity" broadly to include chemical dispersal, electromagnetic emissions, and other deliberate environmental alterations. Violators face a class D felony charge (up to 5 years in prison and fines up to $10,245), with each day of violation treated as a separate offense. The Department of Public Safety enforces the ban through immediate cease-and-desist orders carrying court-like authority and can refer federal programs to the Iowa Air National Guard if needed.
