Environment (Air Quality)

HB 3150 requires the Air Conservation Commission to end all motor vehicle emissions inspection programs established under the Air Quality Attainment Act (sections 643.300-643.355) by January 1, 2028. This bill directly affects vehicle owners in jurisdictions currently requiring emissions testing and the agencies managing those programs. The key provision mandates a specific, mandatory suspension date for these inspections, replacing any existing requirements. The bill is pending in the legislature (introduced January 2026) and would eliminate a current regulatory requirement if passed. It does not create new programs but ends an existing one by a fixed deadline.

HB 1803 requires Missouri's Air Conservation Commission to suspend all motor vehicle emissions inspections by January 1, 2028. This affects all Missouri vehicle owners currently required to undergo emissions testing under the state's existing program. The bill mandates the suspension of the program established under Missouri's Air Quality Attainment Act. The change takes effect automatically on the specified deadline without further legislative action.

HB 2232 focuses on modernizing Missouri's vehicle registration and license renewal systems, not on emissions inspections as its title suggests. The bill repeals outdated vehicle registration sections and creates new provisions for online license renewals, allowing remote applications via the Department of Revenue website with specific vision certification requirements (e.g., optometrist verification within 12 months). It also establishes fleet vehicle registration rules, including special "Fleet Vehicle" license plates and biennial registration options for owners with 10+ vehicles. The bill directly affects drivers seeking remote license renewals, fleet vehicle owners, and the Department of Revenue, replacing in-person processes with digital alternatives. Note: The bill's title references emissions inspections, but the actual text addresses vehicle registration systems, indicating a possible title error.

HB 1873 requires Missouri's Air Conservation Commission to terminate the state's motor vehicle emissions inspection program by January 1, 2028, as established under the Air Quality Attainment Act. The bill repeals existing laws governing emissions inspections and replaces them with new sections focused on vehicle license renewal and fleet registration. This change eliminates the requirement for emissions inspections during vehicle registration, directly affecting vehicle owners who would have been subject to these inspections. The bill terminates the program without establishing a new emissions inspection system.

SB 1033 exempts farm vehicles over ten years old registered as local commercial vehicles for farming operations from Missouri's emissions inspection requirements. This specifically affects older farm equipment used primarily for agricultural transportation, as defined by state law. The bill adds this exemption to existing categories (like electric vehicles and historic cars) under Missouri's emissions inspection statute. It does not change inspection rules for other vehicles or create new requirements for farm operators. The change applies to vehicles meeting the age and registration criteria when sold or transferred.
