HB 3386: Modifies provisions relating to the expenditure of moneys in certain funds by the Department of Natural Resources

HB 3386 creates the "Natural Resources Protection Fund" in the state treasury to hold pollution-related fees, including air and water permit fees, and new 5% of electric power sales tax revenue. It designates specific subaccounts for air pollution control (funded permanently by the tax transfer starting July 2027) and water pollution administration. The bill changes how unspent funds are handled: balances exceeding prior collections no longer revert to general revenue after 2027, and all interest accrues to the fund. These funds, subject to legislative appropriation, directly support the Department of Natural Resources' pollution control programs and enforcement under relevant statutes.

HB 3150: Requires the Air Conservation Commission to suspend by January 1, 2028, any motor vehicle emissions inspection program established under the Air Quality Attainment Act

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: Requires the Air Conservation Commission to terminate by January 1, 2028, the operation of any motor vehicle emissions inspection program established under the Air Quality Attainment Act

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 The bill repeals outdated vehicle registration sections and creates new provisions for online license renewals, allowing remote applications via the Department of Revenue website with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 the Air Conservation Commission to terminate by January 1, 2028, the operation of any motor vehicle emissions inspection program established under the Air Quality Attainment Act

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.

HB 1901: Modifies provisions relating to indoor air quality

HB 1901 replaces Missouri's outdated indoor air quality laws with a new "Missouri Clean Indoor Air Act" (sections 191.2710-191.2750). The bill prohibits smoking and vaping in most enclosed public areas - including bars, restaurants, and workplaces - while defining specific terms like "bar," "cigar-tobacco bar," and "electronic smoking device" (ESD) to clarify enforcement. It directly affects businesses (employers), employees, and public venues by requiring smoke-free environments, with strict rules for cigar-tobacco bars (e.g., freestanding locations and revenue limits). The law includes penalty provisions for violations and explicitly exempts entryways and certain medical devices.

SB 953: Modifies provisions relating to environmental programs within the Department of Natural Resources

SB 953 creates a "Natural Resources Protection Fund" to manage environmental fees, including a new "Missouri Air Emission Reduction Fund" for emissions inspection fees. It changes rules so unspent funds won’t revert to general revenue after 2027 (previously they did), and requires 5% of electric power tax revenue to fund air pollution programs. The Department of Natural Resources will use these funds for environmental programs, while emissions inspection stations must collect and remit fees to the state treasurer. The bill directly affects state environmental agencies, inspection stations, and public programs focused on air/water quality.

SB 1033: Creates provisions relating to the regulation of air quality

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.
