SB 1368 prohibits all weather modification activities in Missouri, defined as releasing chemicals or devices into the atmosphere to alter weather, climate, or sunlight. It makes violations a class E felony and imposes civil penalties up to $200,000. The bill requires airports to report aircraft equipped for potential weather modification starting in 2027 and establishes a public reporting system for violations. The Missouri Department of Natural Resources enforces the law, collects penalties into a conservation fund, and can seek court orders for violations.
SB 1788 - This act restricts expenditure of any local taxes collected by a political subdivision on aviation fuel or the revenues generated by an international airport that is the subject of federal assistance or the subject of assistance from the Missouri Department of Transportation for purposes other than the capital or operating costs of the airport, the local airport system, or any other local facility that is owned or operated by the person or entity that owns or operates the airport that is directly and substantially related to the air transportation of passengers or property. Provisions of this act do not apply to any taxes collected by a political subdivision for sale of a private airport to a public entity if the sale is approved by the Secretary of the U.S. Department of Transportation, funding is provided under federal law for any portion of the public entity's acquisition of airport land, and an amount described in the act under federal law to that airport for purposes other than land acquisition, is repaid to the Federal Department of Transportation by the private owner. Repayments referred to in this act shall be treated as a recovery of prior year obligations. Nothing in this act may be construed to prevent the use of a state tax on aviation fuel to support a state aviation program or the use of airport revenue on or off the airport for a noise mitigation purpose.

The bill's official abstract ("Modifies and creates new provisions relating to illegal immigrants") provides no substantive details about its content, provisions, or intended effects. No specific mechanisms, affected groups, or policy changes are described in the available information. Since the bill is only at the "S First Read" stage (2026-02-26) with no further details provided, a meaningful summary cannot be generated. The abstract alone is insufficient to describe what the bill does or who it would affect.
HB 3515 prohibits Missouri state and local governments from using taxpayer funds to enforce federal emissions regulations on diesel-powered commercial vehicles, including trucks, buses, and transporters. It directly affects state agencies, local officials, and businesses operating these vehicles by banning enforcement actions like inspections or fines related to emissions control devices. The law imposes $100,000 civil penalties on entities employing officials who knowingly enforce such federal rules, and allows lawsuits to recover attorney fees and costs. Violators must pay court costs if sued, with no immunity for government employees acting under federal authority.
HB 3463 limits the total length of trains operated by railroads on public main tracks or branch lines to 8,500 feet. This directly affects railroad companies operating within the state, requiring them to comply with the new length restriction. The bill grants the Department of Transportation authority to create specific rules for measuring train lengths, granting exemptions for certain routes, and imposing penalties for violations. These rules must follow state administrative procedures and will take effect only after meeting legal requirements.
SB 1084 modifies how Missouri allocates state funds to regional planning commissions. It requires a 50-50 match: for every $1 the state provides, local governments must contribute $1. The bill sets specific annual funding caps, limiting East-West Gateway and Mid-America Regional Councils to $130,000 each, and most other commissions to $50,000 each. Starting July 1, 2026, these caps will automatically adjust annually based on the consumer price index to account for inflation. This bill directly affects 18 regional planning commissions across Missouri by changing their funding structure and maximum allowable grants.
SB 1179 - This act provides that any tax, excise, license or fee upon, measured by or with respect to the importation, receipt, manufacture, storage, transportation, sale or use of fuel used for propelling motor vehicles authorized by a political subdivision shall expire five years after enactment unless reauthorized by a two-thirds majority vote of the people of the political subdivision. This act is identical to SB 831 (2025). TAYLOR MIDDLETON
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 2774 prohibits state or local laws, rules, or regulations that restrict the sale or use of specific items based solely on their fuel type. It directly affects owners and sellers of motor vehicles, common tools (like generators, lawn mowers, and leaf blowers), and farm equipment. The bill blocks restrictions targeting fuel sources - such as banning gasoline-powered equipment in certain areas - by preventing such rules from being enacted. This creates a statewide standard, ensuring these items cannot be regulated differently simply because they run on gasoline, diesel, or other fuels.
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.
