Cal. Code Regs. tit. 17, § 95488.9
(a) Substantiality Requirements.
(1) The substantiality requirement applies in the scenario listed below. The substantiality requirement does not apply when re-applying for a Provisional pathway with a new operational data period due to a process change, or pathways that qualify for Tier 2 due to the use of low-CI process energy sources, or use of carbon capture, as described in section 95488.9(c), or when replacing a certified CI after annual verification using the process described in section 95488.10(a)(6).
(2) The applicant seeking to apply under the scenario described in subsection (1), above, must demonstrate, to the Executive Officer's satisfaction, that the proposed pathway meets the following requirements:
(A) The source-to-tank carbon intensity of the fuel under the proposed pathway meets one of the following two criteria. “Source-to-tank” means all the steps involved in feedstock production and transport, finished fuel production and transport. A source-to-tank CI does not include the carbon intensity associated with the use of the fuel in a vehicle and does not include the LUC modifier.
(b) Temporary Fuel Pathways.
(4) New Temporary Fuel Pathways. An entity can apply for the use of a Temporary fuel pathway CI value if it appears in Table 8 in this subarticle or if the Executive Officer approves a new Temporary pathway (for a fuel or feedstock-fuel combination not found in Table 8) and publishes it on the LCFS website. Any new Temporary pathway proposed by the Executive Officer will be posted for 45 days for public comment prior to certification. The posted information will include the rationale for assigning the CI to that particular Temporary pathway. If these comments require significant revision of the originally published pathway, a revised pathway will be posted for public comment. Upon certification of a new Temporary pathway created by the Executive Officer, the pathway will be available for reporting for the quarter in which it is certified.

(c) Provisional Pathways. As set forth in sections 95488.6(a) and 95488.7(a), LCFS fuel pathways are generally developed based on 24 months of operational data. The Executive Officer may consider Provisional pathway applications from 1) facilities that have been in operation for less than 24 months, or 2) existing facilities that can demonstrate a process change has been implemented, based on at least three months of operational data. Based on timely reports, the fuel reporting entity may generate credits or deficits using a provisionally-certified CI.
(d) Substitute Pathways for Reporting Exports and Other Transaction Types. If a fuel reporting entity is unable to determine the pathway for reporting a fuel transaction type listed in subsection (1) below, a Substitute pathway corresponding to the fuel type must be used for reporting. Substitute pathways have CI values based on weighted average CIs of that fuel in the prior year, and are provided on the LCFS website.
(1) The Substitute pathways are only available in the LRT-CBTS for reporting the following transaction types:
(e) Design-based Pathways. As set forth in sections 95488.6(a) and 95488.7(a), LCFS fuel pathways are generally developed based on 24 months of operational data. However, in order to encourage the development of innovative fuel technologies, an applicant may submit a Design-based pathway application in the AFP for a fully engineered and designed facility with no operational data.
(f) Carbon Intensities that Reflect Avoided Methane Emissions from Dairy and Swine Manure or Organic Waste Diverted from Landfill Disposal.
(1) A fuel pathway that utilizes biomethane from dairy cattle or swine manure digestion may be certified with a CI that reflects the reduction of greenhouse gas emissions achieved by the voluntary capture of methane, provided that:
(2) A fuel pathway that utilizes an organic material may be certified with a CI that reflects the reduction of greenhouse gas emissions achieved by the voluntary diversion from decomposition in a landfill and the associated fugitive methane emissions, provided that:
(3) Carbon intensities that reflect avoided methane emissions from dairy and swine manure or organic waste projects are subject to the following requirements for credit generation:
(g) Sustainability Requirements for Biomass.
