| H3083 | Air Quality | Immediately | Sine die | |
| South Carolina's H. 3083 takes a minimalist approach to weather modification prohibition, adding a simple ban on intentional atmospheric emissions for climate purposes without specifying penalties, enforcement mechanisms, or exemptions—leaving implementation entirely to existing air quality regulations. |

| H3915 | South Carolina Clean Air Act | Immediately | Sine die | |
| 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. |

| H4010 | South Carolina Clean Air Act | Immediately | Sine die | |
| 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. |

| S0110 | Air Quality | Immediately | Sine die | |
| 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. |

| H4624 | South Carolina Clean Air Act | Immediately | Sine die | |
| 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. |
