Environmental protection: air pollution; dispersion of substances or objects into atmosphere; prohibit for purposes of affecting weather. Amends 1994 PA 451 (MCL 324.101 - 324.90106) by adding sec. 5514b.

HB 4304 prohibits intentionally injecting, releasing, or dispersing chemicals or devices into the atmosphere to alter weather patterns or sunlight intensity. This directly affects individuals or entities conducting weather modification activities, such as cloud seeding or experimental atmospheric interventions. The bill adds this specific prohibition to Michigan's environmental protection law, making such actions illegal under state statute without requiring additional regulatory steps. It focuses on preventing intentional atmospheric interference for weather-related purposes.
