H3083 Died for lack of action

H3915 Died for lack of action

South Carolina Clean Air Act

South Carolina's H. 3915 establishes a mid-tier enforcement approach to weather modification, combining federal-level felony penalties with whistleblower protections for citizens suing the government, while notably omitting the more aggressive airport employee prosecution and bounty provisions found in companion bill H. 4624.

Last action
H4010 Died for lack of action

South Carolina Clean Air Act

South Carolina's H. 4010 represents the most agriculture-friendly version of the state's weather modification bills, explicitly exempting both cloud seeding and crop dusting operations while notably omitting any criminal penalties or enforcement mechanisms for violations—essentially creating a prohibition without teeth.

Last action
H4624 Died for lack of action

South Carolina Clean Air Act

South Carolina's bill establishes the nation's most aggressive enforcement regime against weather modification activities, featuring life imprisonment for third-time offenders and an unprecedented private citizen lawsuit provision that awards damages without requiring proof of harm—creating a de facto bounty system against stratospheric aerosol injection operations.

Last action
S0110 Died for lack of action

Air Quality

South Carolina's S. 110 is the Senate companion to the minimalist House approach, creating a bare-bones weather modification prohibition without penalties or exemptions—but its referral to the Medical Affairs Committee rather than environmental or agriculture committees signals a unique legislative focus on public health impacts.
