A BILL for an Act to create and enact a new chapter to title 23.1 of the North Dakota Century Code, relating to harmful atmospheric activity; and to provide a penalty.

HB 1514 would have prohibited "harmful atmospheric activity" in North Dakota, including weather modification techniques like cloud seeding, stratospheric aerosol injection, and unmarked aircraft operations that could harm humans or the environment. It defined specific prohibited actions, set a class C felony penalty with up to $500,000 fines for violations, and created a reporting system for citizens to document suspected incidents with evidence like photos or radiation measurements. The bill also established technical limits for electromagnetic radiation and required sheriffs or the environmental director to investigate reports within 24 hours. This bill failed to pass in the North Dakota legislature on February 24, 2025, with 28 votes in favor and 63 against.
