Wyoming's HB 12, the Clean Air and Geoengineering Prohibition Act, bans releasing substances into the state's airspace for climate, weather, or solar radiation modification (like stratospheric aerosol injection or solar radiation management). It directly affects entities conducting such atmospheric experiments, including research groups, corporations, or government agencies, while exempting commercial aviation, cloud seeding, agricultural operations, and fire suppression. The law requires the Wyoming Department of Environmental Quality to monitor airspace and enforce the ban by issuing cease-and-desist orders for violations. It explicitly permits existing activities like cloud seeding and standard aviation emissions, focusing only on intentional modifications not already authorized by law.
HB 18 authorizes the Wyoming State Museum to charge fees for nonresident admissions, museum events, and other services. Fees collected would be deposited into a dedicated "museum enterprise fund" (renamed from the previous department of commerce enterprise fund), which can only be spent with legislative approval. This bill directly affects nonresident visitors and changes how the museum's revenue is managed. It does not impact current admission policies for Wyoming residents or alter the museum's core operations.
This Wyoming bill (SF 40) changes the zoning protest process for cities and towns. It requires property owners to demonstrate specific harm and gather support from either 50% of owners within 500 feet of the proposed change or 50% of owners covering the affected area - raising the threshold from the previous 20% requirement. The change applies only to protests filed on or after July 1, 2025, and prevents zoning changes from taking effect without a 3/4 majority vote of the governing body. This directly affects property owners seeking to block local zoning modifications.
This bill establishes a uniform 9.5% property tax rate for all residential real property in Wyoming, including owner-occupied primary residences, single-family homes, condos, mobile homes, and related land (up to 35 acres). It defines "owner occupied primary residence" as property where the owner lives at least six months annually and clarifies "residential real property" to include dwellings for up to four families. The change applies to all residential property classes, replacing prior differentiated rates, and takes effect for tax year 2025. It directly affects Wyoming homeowners and property assessors by standardizing the tax calculation method.
Wyoming's HB 154 clarifies that voting more than once in the same federal election - including voting in another state and then voting in Wyoming - is considered illegal "false voting." It directly affects voters who attempt to cast multiple ballots across states for the same election and election officials responsible for enforcement. The bill adds specific language to the false voting statute and authorizes the Secretary of State to request investigations into such cases, requiring county sheriffs to investigate when requested and refer cases to prosecutors if warranted. The law takes effect on July 1, 2025.
HB 47 allows Wyoming's Secretary of State to charge a fee for expedited processing of specific government filings, such as business registrations or land records covered under Titles 17, 34, or 40 of Wyoming statutes. Filers requesting faster processing would pay a maximum fee of $5,000, with the exact fee determined by the Secretary of State based on actual costs. The bill clarifies that expedited filings do not change the legal timing or priority of the document compared to standard submissions. It takes effect on July 1, 2025.
HB 121, the "Hospital Price Transparency Act," requires Wyoming hospitals to publicly list detailed pricing for all services and items they provide. Specifically, hospitals must display a machine-readable online list showing standard charges - including gross charges, negotiated rates with insurers, and discounted cash prices - for every service, plus a simplified consumer-friendly list for common "shoppable" services like routine procedures. This applies to all licensed Wyoming hospitals and must be posted on their websites free of charge, without requiring login or personal information. The law also prohibits debt collection actions against patients from facilities that fail to comply and directs the Department of Health to monitor enforcement.
HB 183 amends Wyoming's net metering rules by setting a 25-kilowatt maximum per meter for residential systems and 200 kilowatts per meter for nonresidential systems. It allows customer-generators to combine multiple meters on their property under specific conditions, such as being physically located on the same premises, using the same electricity rate, and served by the same power line. Electric utilities must report annually by July 1 on the total installed capacity and peak demand of net metering systems, with additional reporting to a legislative committee when systems reach 5% of an utility's peak demand. The bill takes effect on July 1, 2025.
HB 144 clarifies the membership requirements for Wyoming county canvassing boards that certify election results. It specifies that boards must include the county clerk plus two voters from different political parties, appointed by the county clerk if major party committees fail to select members. The bill updates election code sections to require this bipartisan composition, sets compensation equal to election judges, and mandates that canvassing for special district elections be completed within seven business days. This affects county clerks, election boards, and voters in all counties conducting elections.
Wyoming's HB 286 establishes a fixed annual mountain lion hunting season running from September 1 to August 31 each year. It removes all previous restrictions, including hunt areas, mortality limits (statewide or per area), bag limits, and time restrictions - allowing mountain lions to be taken 24/7 with a valid license. Hunters holding valid antelope, deer, or elk licenses can now take mountain lions without needing a separate mountain lion permit, and the bill repeals prior "mountain lion pursuit seasons." The law also requires the Game and Fish Commission to issue possession tags for mountain lions taken and permits trapping/snaring under new rules. This bill directly affects hunters and wildlife management practices by significantly expanding hunting flexibility while removing regulatory limits.
HB 332 would have prohibited Wyoming counties from using public funds to pay for association membership fees, travel, lodging, or meals related to county participation in local or national county official associations. It would have required all documents related to county association activities (like agendas, financial reports, and communications) to be made public records and mandated that county officials document weekly time spent on such activities, submitting monthly reports to their county board. The bill directly affected county commissioners and elected county officials who engage with associations. It died in committee on March 4, 2025, and would have taken effect July 1, 2025, if enacted.
HB 322 clarifies that Wyoming's Secretary of State has the authority to create binding rules and directives for county election operations, directly affecting county clerks who serve as local election officers. The bill amends election statutes to require county clerks to follow all rules and written instructions issued by the Secretary of State under state election law. This establishes the Secretary of State as the central authority for uniform election administration across all counties. The bill takes effect July 1, 2025, but died in committee in March 2025.
