In exercising its authority under this section, the department shall consider all of the following:
(a) Advances in technology available to fuel providers to achieve the further reduction.
(b) The need to maintain fuel quality and availability.
(c) The goals of the department's MI healthy climate plan.
(2) The department shall develop a mechanism that automatically adjusts the stringency of the schedule of annual standards if there is a sustained oversupply or undersupply of credits for 2 years.
Sec. 7. (1) The department shall establish a process to review fuel pathways submitted by credit generators. Fuel pathways must be calculated using the GREET model. The fuel pathway review process must meet both of the following requirements:

Sec. 9. (1) The department shall establish a fair and reasonable program for tradable credits and deficits. The generation of credits must use a life-cycle emissions performance-based approach that is technology and feedstock neutral to achieve fuel decarbonization. Credits must be provided for all carbon dioxide and carbon dioxide equivalent reductions as determined by the GREET model. The program must include all of the following:
(a) The registration of credit aggregators and of credit generators that have not designated a credit aggregator.
(b) A market mechanism that allows credits to be traded or banked for future use, including an exchange-based credit trading mechanism.
(c) Credit market transaction fees, established in the first year of the program, to cover the administrative costs of the program. The transaction fee schedule must be designed to generate more than 50% of the revenue from deficit generators. The department shall disclose the fee schedule before the deadline for registration under subdivision (a).
(d) Procedures to verify the validity of credits and deficits.
(e) The ability to carry over up to 5% of deficits each year if credits are unavailable under section 11.
(2) Beginning on the effective date of this act, the department shall allow the generation of credits associated with fuel produced through infrastructure that existed before the effective date of this act or the start date of program requirements.
(3) Aviation fuel is exempt from the standard, but sustainable aviation fuel is eligible to generate credits on an opt-in basis.
(4) Fuel used to power a marine vessel is exempt from the standard, but competitive fuel used to power a marine vessel is eligible to generate credits on an opt-in basis.
Sec. 11. (1) A fuel provider that is a deficit generator during a year shall eliminate the deficit by doing either or both of the following:
(a) Producing or importing transportation fuels whose carbon intensity is at or below the level of that year's annual standard.
(b) Purchasing credits to offset the deficit.
(2) A fuel provider that violates subsection (1) may be ordered to pay a civil fine of 200% of the value of the credits needed to offset the violation. The civil violation may be prosecuted by the prosecutor of the county in which the violation occurred or by the attorney general.
Sec. 13. The department shall collaborate with MDOT and the office to develop a compliance reporting process, including forms, for credit generators and deficit generators. The department shall regularly post on the department's website data on deficit and credit generation and credit prices.
Sec. 15. By 2 years after the effective date of the rules promulgated under section 17, the department shall submit a report detailing program implementation to the senate and house of representatives committees responsible for transportation, energy, and natural resources legislation. The department shall make summary information on the program available to the public.
Sec. 17. (1) By 18 months after the effective date of this section, the department shall promulgate rules to implement this act under the administrative procedures act of 1969, 1969 PA 306, MCL 24.201 to 24.328.
(2) In developing the rules, the department shall do all of the following:
(a) Consult with MDOT and the office.
(b) Solicit input from stakeholders, including, but not limited to, fuel providers, consumers, agricultural organizations, environmental and environmental justice organizations, technology providers, and rural, urban, and tribal communities, through a task force, working groups, public meetings, and other means.
(c) Endeavor to do all of the following:
(i) Support the growth and creation of high-paying jobs in the fuels and automotive industries in this state.
(ii) Ensure transparency and fair competition.
(iii) Complement and further both of the following:
(A) Existing state and federal fuel, transit and mobility, transportation decarbonization, infrastructure, and greenhouse gas emissions policies and programs.
(B) Existing efforts by the agricultural sector to increase the adoption of practices that improve soil health and water quality.
(3) The rules promulgated in accordance with this act must do at least all of the following:
(a) Establish energy economy ratios.
(b) Identify safeguards and incentives to protect biodiversity, reduce potential land use impacts, consider unintended consequences at scale, safeguard customer and farmer privacy, and promote equity.
(c) Provide credit price caps or other cost containment measures that the department considers necessary to harmonize market credit costs and ensure that credit prices do not significantly exceed credit prices in other jurisdictions with similar programs to reduce the carbon intensity of transportation fuels. The department shall design any cost containment measure to provide financial disincentives for regulated persons to rely on the measures for purposes of program compliance instead of seeking to generate or acquire sufficient credits.
(d) Establish procedures to allow credit generators to generate credits for electric vehicle charging that occurs in residences. The department shall set a goal for the percentage of the credit revenue generated under this subdivision to be spent to support transportation electrification and transportation emission reduction programs for the primary benefit of disadvantaged communities, low-income communities, or rural communities. The department shall develop projects and identify goals under this subdivision in consultation with credit generators, communities, community leaders, and environmental justice advocates, including members of the Michigan advisory council on environmental justice.
(e) Establish a process to create procedures for biofuel producers to calculate a unique carbon intensity score for biofuel feedstocks from cropland-derived biofuels. A biofuel producer may use the unique carbon intensity as an alternative to the statewide average carbon intensity scores. The procedures must use the GREET model and other models and must take into account the impacts on farm-related emissions and sequestration of greenhouse gases. The procedures must include a methodology for calculation, monitoring, and annual third-party auditing and verification, including the all of the following:
(i) Soil-healthy farming practices and fertilizer best-management practices that meet United States Department of Agriculture standards in effect on the effective date of this act or subsequent standards approved by the department and MDARD as reasonable and consistent with the purposes of this subdivision. The practices may include, but are not limited to, reduced tillage farming and no-till farming.
(ii) Reduced carbon inputs through practices including, but not limited to, reduced on-farm fuel use, reduced use of fertilizers and other inputs, and use of low-carbon-intensity fertilizer.
(iii) Practices that capture more carbon than traditional cropping methods, as established by the best available research and verified by the department or a land grant university. The practices include, but are not limited to, use of cover crops, use of continuous living cover cropping, and application of biochar.
(4) The department shall prepare and post on its publicly accessible website an annual report summarizing the results of third-party auditing and verification of on-farm practices under subsection (3)(e). Data collected and verified under subsection (3)(e) and this subsection is confidential and exempt from disclosure under the freedom of information act, 1976 PA 442, MCL 15.231 to 15.246.
