HB 259: Revise fish and wildlife commission techniques for gray wolf management

HB 259 revises Montana's gray wolf management rules to give the Fish and Wildlife Commission more flexibility in controlling wolf populations. It allows landowners to kill wolves threatening livestock or safety without a hunting license (subject to reporting and annual quotas), expands hunting/trapping on private land at night using thermal/infrared scopes, and permits unlimited wolf harvest in high-population areas. The bill directly affects landowners, hunters, and the Fish and Wildlife Commission, which must implement these changes. Key provisions include new landowner take rules, modified hunting seasons based on regional wolf numbers, and immediate implementation upon enactment.

SB 537: Generally revise marijuana tax laws

SB 537 revises Montana's marijuana tax revenue distribution, directing funds from the marijuana state special revenue account to new and existing state accounts. It requires transferring excess funds annually to specific accounts, including 12% to the HEART account for addiction treatment and mental health programs, 20% to wildlife habitat projects, and 14% to behavioral health initiatives. The bill also allocates funds for law enforcement canine training, sexual assault evidence kits, and homeless shelter support, while modifying existing transfer rules for agencies like the Department of Fish, Wildlife, and Parks. These changes apply to all state agencies receiving marijuana tax revenue under Montana law.

HB 283: Revise laws for hunting licenses lotteries

HB 283 would allow Montana's wildlife commission to issue one male mountain sheep and one male Shiras moose hunting license annually through a lottery or auction, instead of traditional methods. Hunters seeking these licenses would enter the lottery, and any proceeds from sales would fund conservation efforts for these species, with wildlife groups allowed to retain up to 10% of proceeds to cover lottery costs. The bill specifies that all remaining funds must directly benefit mountain sheep and moose management, supplementing existing department budgets. Note: This bill was vetoed by the governor and the legislature failed to override the veto, so it is not currently law.

HB 368: Generally revise water supply requirements for coal-fired generating units

HB 368 requires operators of coal-fired power plants (over 200 megawatts) in Montana to provide ongoing water access for residential and commercial use to the city or town where the plant is located if the plant closes. It mandates operators maintain water delivery systems until cleanup meets environmental standards, with financial assurance for water supply 30 years after closure. The bill directly affects plant operators and local governments, ensuring continued municipal water access even after plant retirement. Key provisions include revised definitions for "retired" plants, cleanup criteria, and requirements for operators to cover long-term water needs.

SB 472: Revise penalties for violations under 310 permit process

SB 472 removes the previous $250,000 cap on civil penalties for repeated violations of Montana's stream protection rules (under the Natural Streambed and Land Preservation Act). It specifically exempts forest activities that follow state forestry rules from these penalties. The bill affects developers, loggers, or others working in stream zones who violate permit requirements, allowing penalties to grow without limit for ongoing violations. It takes immediate effect upon approval.

SB 481: Prohibit motorboats and motorized watercraft on Class 2 waters

SB 481 prohibits motorboats and personal watercraft on designated Class II waters in Montana. It directly affects recreational users who operate motorized watercraft on these specific waterways, which are likely smaller or sensitive streams or rivers under state classification. The key provision amends Montana law to explicitly ban such motorized use on Class II waters, replacing previous language that only implied restrictions. The bill also requires the commission to adopt rules for managing recreational use on Class I and II waters, including procedures for limiting or restricting activities.

SB 403: Grant the fish and wildlife commission authority to set muzzleloader season

SB 403 would have granted Montana's Fish and Wildlife Commission the authority to set the specific dates and duration for the state's annual muzzleloader heritage hunting season, replacing a previously fixed schedule. This change would directly affect hunters using traditional muzzleloading rifles for deer and elk during this designated season. The bill would have allowed the Commission to adjust the season dates and length based on wildlife management needs, rather than requiring it to follow a fixed timeline (e.g., "second Saturday after regular season for 9 days"). The season itself would have permitted hunting deer or elk with muzzleloaders using specific ammunition and firearm types, as defined by existing regulations.

SB 427: Provide trapping setback distances for certain roads and trails

SB 427 establishes minimum distance requirements for trapping on Montana's public lands near developed areas. It requires trappers to set traps at least 50 feet from roads/trails, 1,000 feet from campgrounds/recreation sites (including boat ramps), and 300 feet from trailheads (with 1,000 feet for lethal traps). The bill directly affects trappers operating on public lands, particularly those near popular recreation areas, and gives the Fish, Wildlife and Parks Commission authority to adjust these distances in high-use zones. The provisions aim to reduce conflicts between trapping activities and public recreation by creating physical buffers around developed sites.

SB 473: Prohibit weather modification.

SB 473 prohibits most weather modification activities in Montana, specifically banning large-scale "geoengineering" projects like spraying particles into the atmosphere to alter climate (e.g., stratospheric aerosol injection or marine cloud brightening). It exempts established cloud seeding practices used for agriculture and snowmaking under existing law (85-3-101 through 85-3-424). The bill directly affects researchers, companies, or entities conducting weather-altering experiments within Montana’s borders. Key provisions ban intentionally releasing chemicals or devices for weather control, temperature modification, or sunlight intensity changes, except for permitted cloud seeding. The law takes immediate effect upon enactment.

HB 176: Require unlimited wolf hunting quota when population is at or above 450 wolves

House Bill 176 (HB 176) revises Montana's wolf hunting laws, primarily affecting the Fish and Wildlife Commission, wolf hunters, trappers, and landowners. The bill mandates an unlimited statewide gray wolf hunting quota when the state's wolf population reaches or exceeds 450 wolves. Under this quota, the Commission must authorize multiple hunting licenses per applicant, allow an individual to harvest an unlimited number of wolves, permit the use of bait for hunting or trapping, and allow night hunting on private lands with artificial light or night vision scopes. It also requires consistent data modeling for wolf population estimates.
