HB0899 Sine die

AN ACT to amend Tennessee Code Annotated, Title 47, Chapter 18 and Title 68, Chapter 201, relative to weather modification.

Tennessee's bill takes an unusual enforcement approach by routing weather modification violations through consumer protection law rather than creating direct criminal prohibitions, treating cloud seeding as essentially a form of commercial fraud. The narrow application only to "weather-related companies" makes a significant gap—the same activities would remain legal if conducted by entities outside this defined category.

HB1112 Sine die

AN ACT to amend Tennessee Code Annotated, Title 58, Chapter 2 and Title 68, Chapter 201, relative to weather modification.

Tennessee's HB 1112 creates one of the more aggressive enforcement frameworks among state weather modification bills, combining criminal misdemeanour charges with a substantial $100,000-per-violation administrative fine and extending liability up the supply chain to anyone providing materials with knowledge of their intended use. The bill has already passed the House 69-21 and crossed over to the Senate.

HB2063 Substituted by SB2691

AN ACT to amend Tennessee Code Annotated, Title 4; Title 5; Title 6; Title 7; Title 8; Title 39; Title 42; Title 43; Title 44; Title 55; Title 58; Title 59; Title 60; Title 65; Title 68 and Title 69, relative to environmental protection.

Tennessee transformed a technical caption bill about permit timelines into a comprehensive atmospheric intervention ban through floor amendment, with enforcement tied to existing air quality violations rather than creating new criminal statutes.

Substituted by SB2691.

Last action Effective: 1 Jul 2024
SB2691 Passed

AN ACT to amend Tennessee Code Annotated, Title 4; Title 5; Title 6; Title 7; Title 8; Title 39; Title 42; Title 43; Title 44; Title 55; Title 58; Title 59; Title 60; Title 65; Title 68 and Title 69, relative to environmental protection.

Tennessee's geoengineering ban includes legislative findings asserting that federal atmospheric experiments may occur in the state, while its own fiscal analysis assumes no such activities are happening or will occur, creating an unusual disconnect between the stated justification and the projected impact.

Tennessee SB2691 passed both chambers and became Public Chapter 709 effective July 1, 2024.
