SB 568: Investments; requiring all shareholder and ownership interest votes to be in the pecuniary interest of the beneficiary. Effective date. Emergency.

SB 568 requires Oklahoma state agencies and their investment managers to vote shares solely based on financial returns for pension beneficiaries, not social or environmental considerations. It prohibits following proxy adviser recommendations unless those advisers commit in writing to prioritize financial interests. Agencies must annually report all proxy votes - including management and adviser recommendations - to the State Treasurer via a public website. This applies to all state investments held for retirement plans, such as pension funds.

SB 621: Solid waste management; exempting combustor entities subject to certain state and federal oversight from certain subsequent regulation. Emergency.

SB 621 exempts municipal waste incinerators already regulated under federal rules (40 C.F.R. Part 60 Subpart Eb) and Oklahoma's Department of Environmental Quality from future state regulations covering specific waste types, including biomedical, hospital, commercial, and industrial waste incineration. The bill directly affects waste management facilities operating under existing federal and state oversight. It prevents the Department of Environmental Quality from imposing additional state rules on these facilities for the listed waste streams. The bill was introduced as an emergency measure to take immediate effect upon passage.

SB 311: Taxation; gross production tax on certain interests; modifying tax rate. Effective date.

This bill modifies Oklahoma's gross production tax rates for oil and gas. It reduces the tax rate from 7% to 5% for oil and gas production from wells spudded before July 18, 2018, for 36 months. It also creates two new exemptions: a 5-year tax exemption for secondary/tertiary recovery projects (approved after July 1, 2022) and a 24-month exemption for wells completed using recycled water (proportional to recycled water use). Refunds for these exemptions are capped at $15 million annually for recovery projects and $10 million for recycled water projects. The bill directly affects oil and gas producers operating in Oklahoma.

HB 4428: Public finance; terms; Board of Trustees; votes; proxy proposal; pecuniary factors; exception; report; publish; effective date.

HB 4428 requires Oklahoma's pension benefit plans (like state retirement funds) to vote on shareholder proposals solely based on financial impact, banning consideration of environmental, social, or political goals. It mandates that pension boards base all voting decisions on "pecuniary factors" (financial risk/return) to maximize shareholder value, and prohibits proxy advisors from providing recommendations that include non-financial considerations. Boards must annually report all votes, including their decision, management's stance, and any proxy advisor's recommendation, publishing the report online by March 1 each year. The law applies to all state pension systems and takes effect November 1, 2026.

SB 457: Motor vehicles; creating the Oklahoma Diesel Engine Freedom Act. Emergency.

SB 457, the Oklahoma Diesel Engine Freedom Act, invalidates federal rules requiring diesel exhaust fluid (DEF) in diesel engines used within Oklahoma, declaring such requirements unconstitutional under the 10th Amendment. It prohibits state agencies and officials from enforcing federal DEF mandates and legalizes the sale and use of diesel engines that do not require DEF in the state. The bill imposes fines up to $5,000 per violation for state entities enforcing federal rules and repeals an existing Oklahoma emission control law. It applies only to vehicles operating solely within Oklahoma, not to interstate commerce.

HJR 1003: Oklahoma Constitution; eminent domain; wind energy projects; ballot title; filing.

HJR 1003 proposes adding a new constitutional section to Oklahoma that restricts the use of eminent domain for specific wind and solar energy projects. It prohibits government from taking private land for wind turbine construction or associated transmission lines if the project receives U.S. government financial assistance exceeding 3% of its total cost, or if the transmission lines exclusively serve federally incentivized wind/solar projects. The bill does not affect voluntary land purchases or projects without federal funding or tax incentives. This would directly impact energy developers seeking to build wind/solar infrastructure relying on federal support, while preserving eminent domain for other projects.

SB 294: State fiscal affairs; the Oklahoma Quick Action Closing Fund; excluding certain industry from eligibility to receive funds. Effective date.

SB 294 amends Oklahoma's Oklahoma Quick Action Closing Fund to exclude electric vehicle manufacturing businesses (specifically those using NAICS code 336110) from eligibility for funding. This bill directly affects companies in the electric vehicle manufacturing industry, preventing them from receiving economic development funds intended for high-impact business projects. The change modifies existing eligibility rules under the fund's statutes without altering other provisions for qualifying industries or the fund's administration. The exclusion applies to all applications for the fund, including those seeking rebates under the Oklahoma Film Enhancement Rebate Program. The bill does not change the fund's purpose, which remains supporting job creation, capital investment, and economic development through targeted business incentives.

HB 1452: Revenue and taxation; Green Energy Subsidy Recapture Tax Act; definitions; purpose; tax levy; exemptions; reporting procedures; remittance; apportionment of revenues; effective date.

HB 1452 imposes a state tax on owners of wind, solar, geothermal, and hydroelectric facilities in Oklahoma, equal to the federal production tax credit amount they could have claimed. The tax applies regardless of whether the facility owner actually used the federal credit. Government-owned facilities are exempt from this tax, while private owners must report and pay the tax monthly to the Oklahoma Tax Commission. All revenue collected flows into the state's General Revenue Fund.

HB 1205: Revenue and taxation; repeal; small wind turbine tax credit; effective date.

HB 1205 repeals Oklahoma's tax credit for small wind turbine installations by removing Section 2357.32B from the state's tax code. This change directly affects small wind turbine owners and installers who previously qualified for the credit. The repeal takes effect on November 1, 2025, eliminating the tax incentive for new installations after that date. The bill is procedural and does not create new policy, only removing an existing tax provision.

SB 239: Income tax; limiting credit allowance for zero-emission facilities to certain tax years; limiting carry forward of credit. Effective date.

SB 239 modifies Oklahoma's tax credit for electricity generated by zero-emission facilities (like wind, solar, hydro, or geothermal power plants). It limits the credit to tax years ending by 2025, ending the ability to carry forward unused credits beyond that year. For credits claimed after July 2019, taxpayers must choose between receiving an 85% direct refund or carrying the credit forward for up to 10 years (ending in 2025). This bill directly affects businesses and entities generating eligible renewable electricity in Oklahoma, altering how they can use or access these tax credits.
