Plain-language change summary

In the latest version of SB 5932, legislators added a section clarifying that the carbon intensity and renewable attributes of energy used to produce alternative jet fuel must be properly assigned based on existing utility contracts and disclosures. This change is significant because it ensures transparency in how the energy is sourced for jet fuel production, helping to support the growth of alternative fuels while also fostering clarity for investors. Overall, these modifications aim to boost confidence in the alternative jet fuel market and encourage investment in this sector.

and (b) Provide clarity and a date certain for the availability of existing production tax incentives.
(3) The legislature further intends that the carbon intensity and renewable attributes of the energy purchased for alternative jet fuel production processes is assigned those attributes reported in the tariff, rate schedule, power purchase agreement, or utility-specific contract or that utility's fuel mix disclosure report under which the energy was purchased, and attributed for all processes using that energy in the alternative jet fuel production process.
RCW 70A.535.150 and 2023 c 232 s 3 are each amended to read as follows:
(1) By no later than December 31, 2023, the department must allow one or more carbon intensity pathways for alternative jet fuel.
(2) The department must allow biomethane to be claimed as the feedstock for renewable diesel and alternative jet fuel consistent with that allowable for compressed natural gas, liquefied natural gas, liquefied compressed natural gas, or hydrogen production.
The department must include in the report required by RCW 70A.535.090(1) information that includes the amount, generation date, and geographic origin of renewable thermal certificates representing the biomethane environmental attributes claimed by each reporting entity for the fuels described in this subsection.

2 SB 5932 (4)(a) Beginning for purposes of program year 2026 through 2037, and, after 2037 for all electricity compliant with chapter 19.405 RCW, the department must apply a carbon intensity for electricity that is supplied to an alternative jet fuel manufacturing facility as follows:
(i) The carbon intensity is as provided for the electricity supplied in the rate schedule, tariff, power purchase agreement, or utility-specific contract according to the fuel mix reported in the rate schedule, tariff, power purchase agreement, or utility-specific carbon intensity pursuant to the utility contract or fuel mix disclosure statement;
(ii) The carbon intensity is calculated pursuant to WAC 173-424-630(6), as it existed on January 1, 2026;
and (iii) The specific carbon intensity is applicable to all production processes of the alternative jet fuel manufacturing facility including, but not limited to, the electrolysis of water and carbon dioxide, involved in manufacturing or producing alternative jet fuel and any coproducts including, but not limited to, renewable naphtha, in that facility.
(b) The specific carbon intensity for electricity specified in (a) of this subsection must apply regardless of:
(i) When a renewable electricity product, or specific carbon intensity electricity product, power purchase agreement, rate schedule, or tariff was negotiated or contracted for;
(ii) The date on which the renewable electricity generating facility began operating;
and (iii) The utility's main utility-specific carbon intensity of electricity.
(c) This subsection (4) supersedes the requirements of WAC 173-424-610(9), as it existed on January 1, 2026, as they are applied to an alternative jet fuel manufacturing facility.
The department must update WAC 173-424-610 to conform with the requirements of this section at the department's next otherwise planned update of chapter 173-424 WAC.
