HB 1427 creates tax credits for Oklahoma taxpayers who invest in qualifying clean-burning motor vehicle fuel equipment. It directly affects vehicle owners and businesses that install or purchase equipment allowing vehicles to run on compressed natural gas, hydrogen, liquefied natural gas, or liquefied petroleum gas. The bill provides tiered credits: up to $5,500 for light vehicles (under 6,000 lbs), up to $100,000 for heavy trucks (over 26,500 lbs), and 45% of costs for commercial refueling stations. Credits are limited to new, certified equipment meeting safety standards and must be claimed against state income tax. Unused credits can be carried forward for up to five years.
HB 2976 requires Oklahoma's Department of Environmental Quality (DEQ) to create rules establishing safe water quality levels for aluminum. These rules would set maximum allowable concentrations of aluminum in water to protect aquatic ecosystems and drinking water sources. The bill, amended to take effect in 2028, directly impacts the DEQ (which must develop the rules) and industries discharging aluminum into waterways, such as manufacturing or mining operations.
HB 2100 exempts private lands enrolled in Oklahoma's Conservation Commission Cost-Share Program from eminent domain, meaning the government cannot take these lands for public projects without the landowner's consent. This protection applies to all lands in the program, with exceptions only for projects deemed essential to public health and safety. The bill, effective November 1, 2025, directly affects landowners participating in the Cost-Share Program by safeguarding their property rights during conservation efforts. It codifies this exemption into Oklahoma Statutes (Section 3-3-118 of Title 27A) to ensure long-term stability for conservation initiatives.
HB 4413 requires facilities burning hospital, medical, or infectious waste to comply with existing U.S. Environmental Protection Agency (EPA) air emission standards. It prohibits any facility not meeting current EPA standards, monitoring, reporting, and permitting requirements from burning such waste in Oklahoma. The bill directly affects municipal solid waste incinerators that handle medical waste, mandating they align with federal rules or cease this activity. The law takes effect November 1, 2026, and codifies EPA definitions for medical waste as used in 40 C.F.R. §60.51c.
HB 3402 creates a dedicated revolving fund called the "Biosolids Land Application Research Revolving Fund" within Oklahoma's Department of Environmental Quality (DEQ). The fund will use money the DEQ already receives to cover costs for equipment, staffing, and training related to testing biosolids (treated waste from wastewater processing). It operates as a continuous fund with no annual budget restrictions, allowing the DEQ to directly use these resources for its biosolids research and testing programs. The bill takes effect July 1, 2026.
HB 3724 regulates large energy users by defining "high-demand facilities" as commercial, industrial, or institutional sites using 75 megawatts or more of electricity. The bill prohibits these facilities from receiving taxpayer-funded subsidies (like tax credits or grants) and requires them to fully cover all grid infrastructure costs and water usage impacts. It mandates water recycling, limits daily water withdrawals to 25% of a provider’s current rate, and bans construction by foreign entities or on agricultural land. Additionally, facilities must submit decommissioning plans and comply with local noise rules without exceptions.
HB 1822 requires the Oklahoma Department of Transportation (ODOT) to create a program for identifying, removing, and managing invasive woody species (like Eastern Redcedar and salt cedar) within transportation rights-of-way. The program mandates surveys, prioritized removal plans, eco-friendly removal methods to protect native plants and soil, ongoing monitoring, and collaboration with other agencies. This directly affects ODOT’s operations and land adjacent to state roads. The bill would have taken effect November 1, 2025, but died in conference on May 30, 2025. (Note: The bill’s title references transportation but focuses on environmental management within road corridors.)
SB 263 expands Oklahoma's Terry Peach North Canadian Watershed Water Restoration Act to address harmful woody species like Eastern Redcedar and salt cedar. It creates a revolving fund for water restoration, allowing cost-sharing with landowners, state agencies, and nonprofits for removal methods such as prescribed burns and herbicides. The bill mandates the Oklahoma Conservation Commission to manage the program across at least three project areas in the North Canadian Watershed, focusing on improving water flow, reducing wildfire risks, and restoring grazing lands. It updates definitions, expands eligible participants, and requires studies comparing treated and untreated watersheds. The policy directly affects landowners and local entities managing watersheds in the North Canadian River basin.
HB 2162 creates the "Terry Peach North Canadian Watershed Water Restoration Act" to establish a pilot program for removing harmful woody species like Eastern Redcedar and salt cedar in Oklahoma's North Canadian Watershed. The Oklahoma Conservation Commission will administer the program using a new revolving fund, which can receive state, federal, and private funds, to cost-share with landowners for removal methods like prescribed burns and herbicides. The program aims to improve water flow into the North Canadian River, reduce wildfire risks, protect grazing lands, and restore wildlife habitat by targeting specific invasive plant species. The bill also designates two active project areas (above and below Canton Lake) and requires the Commission to measure species density, create comparison studies, and develop grant programs with local groups. The fund becomes effective November 1, 2025, but the bill died in conference committee on May 30, 2025.
SB 837 updates Oklahoma's rules for special license plates, affecting anyone applying for or displaying these plates. It requires Service Oklahoma to receive 100 prepaid applications within 180 days before issuing new plate types (like Firefighter or Wildlife Conservation plates), and mandates annual renewal with specific fee handling procedures. Funds collected from these plates will continue to support designated causes, such as the Oklahoma State Firefighters Museum, Wildlife Diversity Fund, and Child Abuse Prevention Fund. The bill also repeals outdated provisions and clarifies plate transfer rules, ensuring plates remain tied to the vehicle registration.
