Restricting weather modification activities.

HB 2222 prohibits any activity that intentionally alters weather, climate, or atmospheric conditions within Washington State, including cloud seeding, stratospheric aerosol injections, or dispersing substances like nano-particulates. It directly affects entities conducting such activities - such as corporations, drones, aircraft, or other equipment operators - by banning these practices under penalty of felony charges (up to $1 million fines and 10 years in prison for repeat violations). The bill establishes a reporting system for the Department of Ecology to investigate violations and allows civil lawsuits to enforce compliance. Key provisions define "weather modification" broadly to cover technologies like 5G, lasers, or radar used for atmospheric manipulation. The bill repeals multiple existing statutes to implement these restrictions.
