Reporting schedule

First quarter reporting started May 1, 2023 and will be open through July 31, 2023.

Extended deadlines:

  • Fuel Supply Equipment (FSE) registration for Quarter 1 is now open through May 30, 2023 (previously April 30, 2023).
  • We accepted revised CARB- and OR DEQ-approved fuel pathways through May 15, 2023 (previously April 30, 2023).

As of Jan. 1, 2023, producers and suppliers of high-carbon-intensity fuels must register, report, and meet the requirements of the Clean Fuel Standard program. Producers and suppliers of low-carbon-intensity fuels may opt in and meet the requirements to generate credits.

Information on this page will help you meet the requirements:

Registration

Participants started registering in the Clean Fuel Standard program on Jan. 1, 2023. We developed the Washington Fuels Reporting System (WFRS) to manage all data and processes related to Clean Fuel Standard implementation, including:

  • Fuel pathway certification
  • Fuel transactions reporting and recordkeeping
  • Credit generation and transfers

The Washington Fuels Reporting System (WFRS) includes these modules:

  • Washington Fuels Reporting
  • Credit Bank & Transfer System (CBTS)
  • Alternative Fuel Portal (AFP)

Get started

To register in WFRS-CBTS:

  1. Use the step-by-step user guide in the guidance document library.
  2. Sign up for a Secure Access Washington (SAW) account. SAW is a platform used by Washington state agencies for information security. Skip this step if you already have a business account in SAW.
  3. Sign in to your SAW account.
  4. Add the Air Quality Application portal to your list of services in SAW.
  5. Create a profile in the Air Quality Application portal.
  6. Add the Washington Fuels Reporting System to your list of applications in the Air Quality Application portal.
  7. Open WFRS through the Air Quality Application portal to submit registration materials.
    You won't be able to access your account until we've approved your account. We review all registration materials and call you to verify account details. We may ask for more information. Account approval is the final step in the process and may take several weeks from the date of your initial submission.
  8. After your account is approved, access WFRS through the Air Quality Application Portal and log in.

Program fee

We charge a fee to participate in the Clean Fuel Standard program. This fee covers the cost of administering the program and is based on the estimated budget for the coming year.

The Air Quality Fee Rule — which includes clean fuels program fees — was adopted on Nov. 28, 2022, after 14 months of stakeholder meetings, an economic review, and informal and formal comment periods. This rule details the process for setting the fee in 2023 and beyond. In 2023, we will charge a participation fee for parties that register in the Washington Fuels Reporting System or the Alternative Fuels Portal. Credit generators have a uniform fee amount, which covers 5% of total program costs. Deficit generators have a uniform fee amount, which covers the remaining 95% of total program costs.

  • Deficit generators pay 95% of the program cost.
  • Credit generators pay 5% of the program cost.

2023 final fee, based on 130 registered participants on March 15, 2023:

  • Each deficit generator will pay: $50,649
  • Each credit generator will pay:       $982

Invoicing:

  • Deficit generators will be invoiced in the second quarter of 2023.
  • Credit generators will be invoiced in the third quarter of 2023.

All invoices will be due within 30 days of receipt and must be paid using our online payment system.

Estimated 2023 program budget: $1,865,999

Generators Number of participants
as of March 15, 2023		 Amount
(percent of program cost)
Deficit generators 35 $1,772,699 (95%)
Credit generator 95 $93,299 (5%)

Process for setting the fee

We posted the estimated budget and proposed fee for 2023 on Feb. 1, 2023, with a 30-day public comment period. The proposed fee is based on the number of registered participants on Jan. 30, 2023. We received seven comments during the public comment period.

Estimated 2023 program budget: $1,865,999

This estimate includes:

  • Agency staffing costs: $1,018,919
  • Other costs (e.g., developing WFRS, fuel-supply forecast, cost-benefit analysis): $847,080

Estimated 2023 fee, based on 64 registered participants as of Jan. 30, 2023:

  • Each deficit generator may pay: $77,074
  • Each credit generator may pay:    $2,276
Generators Number of participants
as of Jan. 30, 2023		 Amount
(percentage of program cost)
Deficit generators 23 $1,772,699 (95%)
Credit generators 41 $93,299 (5%)

All participants will pay a small, flat participation fee, to be determined. Deficit generators will pay an additional fee based on the quantity of deficits they generate. The structure will be:

  • Category 1 (highest fee) — top 30% of deficit generators, 70% of fee amount.
  • Category 2 (middle fee) — middle 30% of deficit generators, 20% of fee amount.
  • Category 3 (lowest fee) — lower 30% of deficit generators, 10% of fee amount.
  • The lowest 10% of deficit generators will only pay the flat participation fee.

Why charge a fee for program participation?

We may collect a fee to support program administration, according to RCW 70A.535.130. The Legislature directed us to collect a fee.

Why charge a fee to credit generators?

Credit generators participate voluntarily in the program. We structured the fee to minimize financial barriers to participation. However, we have administrative costs associated with each credit generator’s participation in the program. We determined that a credit-generator fee was an equitable way to recover those costs.

In response to comments and concerns that the fee could be burdensome to small credit generators, we are delaying invoicing credit generators until the third quarter of 2023, to allow more time to prepare payment.

Why charge a flat participation fee instead of a tiered fee based on the number of credits or deficits generated, or number of gallons supplied to Washington?

We must assess the fee by mid-March 2023 for fiscal purposes. Since reporting does not begin until April 2023, no credits or deficits have been generated yet. For 2023, registration information is the only piece of data we have to base the fee on. The rule for clean fuels program fees structured the 2023 fee as a participation fee only.

In the future, 5% of the program cost will be covered by a flat participation fee split equally between deficit and credit generators. The remaining 95% of the program cost will be covered by deficit generators in tiers, based on the number of deficits generated the previous year.

Will you adjust the fee if more participants register after March 15, 2023?

No. For fiscal purposes, we must set the fee on this date to accurately account for program costs. If the amount collected is higher than the actual program costs at the end of 2023, the 2024 fee will be adjusted to account for that difference. If we adjusted the fee as more parties registered throughout the year, then that could penalize participants who registered earlier in the year.

Why charge the fee to designators instead of credit aggregators?

The fee rule determined that the fee will be paid by credit and deficit generators. Credit generators may choose to designate a credit aggregator to report on their behalf, but the registered credit generator must pay the participation fee.

  • "Credit generator" means a person eligible to generate credits by providing clean fuels for use in Washington and who voluntarily registers to participate in the clean fuels program. (WAC 173‑424‑110(42))
  • "Deficit generator" means a fuel-reporting entity who generates deficits in the CFP program. (WAC 173‑424‑110(47))

Therefore, the party generating the credits or deficits must pay the fee — not the credit aggregator representing them.

When will I be invoiced for my fee?

  • Deficit generators will be invoiced in the second quarter of 2023.
  • Credit generators will be invoiced in the third quarter of 2023.

All invoices will be due within 30 days of receipt and must be paid using our online payment system.

Reporting and compliance

Regulated parties and credit-generating entities that opt into the program must:

  • Register with us to:
    • Produce fuel in Washington.
    • Import fuel into Washington.
    • Generate or transact credits for fuels supplied in Washington​.
  • Keep records for each transaction of transportation fuel imported, sold, or supplied for use in Washington.
  • Submit quarterly and annual reports using the Washington Fuels Reporting System. Use the WFRS-CBTS user guide for a step-by-step guide to submit a quarterly report.​

Regulated parties must comply with the Clean Fuel Standard by purchasing a sufficient number of credits to cancel out their deficit balance for each calendar year. Regulated parties can retire credits they generated themselves or purchase credits from other entities. A Credit Clearance Market will provide an additional opportunity for regulated parties to comply with the Clean Fuel Standard if they cannot generate or purchase sufficient credits by the annual report deadline. The Clean Fuel Standard guidance document library has more information about reporting and compliance.

Reporting schedule

Starting May 1, 2023, program participants can report fuel transactions for Quarter 1 of 2023. Reporting for Quarter 1 will be open through July 31, 2023. Reporting for Quarter 2 will start July 1, 2023.

Quarter Dates for all participants Due dates for electric utilities
Quarter 1
(Jan. 1 – March 31)		 Program registration opens Notify us by Jan. 15, 2023, if they intend to generate credits.
In future years, utilities must notify us by Oct. 1.
Quarter 2
(April 1 – June 30)		 Quarter 1 report is due by the end of quarter 2. Provide daily average electric vehicle electricity use data for quarter 1 within 45 days (May 15).
Quarter 3
(July 1 – Sept. 30)		 Quarter 2 report is due by the end of quarter 3. Provide daily average electric vehicle electricity use data for quarter 2 within 45 days (Aug.15).
Quarter 4
(Oct. 1 – Dec. 31)		 Quarter 3 report due by the end of quarter 4. Provide daily average electric vehicle electricity use data for quarter 3 within 45 days (Nov. 15).

When to expect credits

We will assign credits based on the data that participants report each quarter. In 2023, we will assign credits after participants submit quarterly reports and after we verify the data. Credits will be issued after each reporting cycle.

To estimate the number of credits or deficits you may generate in the program, use the Clean Fuel Standard Obligation Calculator. This calculator is a tool for estimation only. It does not change any individual entity's obligations under the Clean Fuel Standard program.

Carbon intensity and fuel pathways

All transportation fuels need a carbon intensity (CI) score to participate in the Clean Fuel Standard program. The fuel type dictates which process is used to determine that carbon intensity. A fuel pathway carbon intensity consists of the sum of the greenhouse gases emitted throughout each stage of a fuel's production and use, also known as the "well-to-wheels" or life-cycle analysis for the fuel. Carbon intensity is expressed as the amount of life cycle greenhouse gas emissions per unit of fuel energy in grams of carbon dioxide equivalent per megajoule (g CO2e/MJ). Carbon intensity includes the direct effects of producing and using this fuel, as well as indirect effects that may be associated with how the fuel affects other products and markets.

Companies, account administrators, and owners or operators of fuel-supplying equipment must register in the Washington Fuels Reporting System (WFRS). Applications are submitted through the Alternative Fuels Portal (AFP). See the WFRS and AFP User Guide in the Clean Fuel Standard guidance document library for detailed information.

There are three ways to determine a carbon-intensity value for use in the Clean Fuel Standard:

  1. If the fuel has a carbon-intensity value approved by the California Air Resources Board (CARB) and/or the Oregon Department of Environmental Quality, the fuel producer can apply to us to accept that value with modifications as needed to reflect its destination to Washington. The fuel producer can submit the application packet sent to CARB or Oregon, and approval from CARB or Oregon. The applicant should also submit a version of the WA-GREET 3.0 model modified to reflect the transportation mode and distance to Washington (not to California nor Oregon). Fuel producers will submit their fuel pathway applications through the Washington Fuels Reporting System.

  2. If the fuel does not have a carbon-intensity value from California or Oregon, then the fuel producer can submit their fuel pathway application to us for certification. We have developed a series of simplified calculators for well-understood fuel types and the WA-GREET model for more complex fuel pathways. These are listed in the "WA-GREET" tab. Fuel producers will submit their fuel pathway applications through the Washington Fuels Reporting System.

  3. If an applicant has applied for a fuel pathway under the second option, but it hasn't been certified yet, they can use temporary carbon-intensity values. See Table 8 in WAC 173‑424‑900.

The Clean Fuels Program Rule (WAC 173-424-630) requires a unique carbon intensity for electricity generated by each electric utility in Washington. In coordination with the Washington State Department of Commerce's Fuel Mix Disclosure annual report (May 2023 annual report), we developed the 2023 Utility-Specific Carbon Intensity.

Washington determines the carbon intensity of fuels on a lifecycle basis using the GREET model. Each individual transportation fuel has a "fuel pathway" that describes how it is made and delivered to Washington for use in vehicles. Each pathway is assigned its own carbon-intensity value. Carbon-intensity values are shown in grams of carbon dioxide equivalent per megajoule of energy (gCO2e/MJ).
