Amends, repeals, and adds to existing law to prohibit unauthorized weather modification activities and to provide penalties, enforcement, and exceptions.

This bill prohibits unauthorized weather modification and solar radiation management activities in Idaho to protect the state’s environment and public health. Weather modification, including cloud seeding and solar radiation management, could have significant negative impacts on agriculture, water supplies, and public welfare if left unregulated. The bill ensures that only authorized projects, such as those by the Idaho Water Resource Board, are allowed, providing oversight to mitigate risks associated with unauthorized weather manipulation. Additionally, the bill removes an unused taxing district related to weather modification that has not been utilized since the 1970s, eliminating unnecessary bureaucratic structures.
