CARB Proposes LCFS Verification Program
by John Sens (EcoEngineers/Ethanol Producer Magazine) Ethanol producers need to watch developments in the California Low Carbon Fuel Standard as the rules are updated. — … Ethanol producers can participate in the California LCFS program, if they complete a pathway application using the CA GREET2.0 model for a Tier 1 or Tier 2 pathway. Selling into California allows ethanol producers to get both state and federal credits for biofuel sold in the state, which has spurred biofuels growth in and outside of California.
CARB is creating a mandatory verification program to stabilize the LCFS that will go into effect in 2019 and holding a series of workshops and discussions this year to inform the public and solicit stakeholder feedback. The first public working meeting focused on ethanol was held Jan. 31. CARB staff discussed key changes to the mandatory verification program in development and the LCFS program. Meeting documents and the future meeting schedule can be found by searching for LCFS meetings at www.arb.ca.gov.
The mandatory verification program would validate the initial 24-month period of operations data needed when applying for a fuel pathway code (FPC) and would verify the average carbon intensity (CI) over a year’s compliance period for a facility to ensure it does not exceed the certified pathway CI value. The program would verify total ethanol production and volumes of ethanol sold using a mass balance and energy assessment and verify volumes claimed as imported or produced in California to ensure proper and accurate reporting. The program would also verify volumes exported out of California.
Ongoing third-party verification will be a central piece of the program. The required operational data and supporting records include:
• Feedstock inputs such as meter records and feedstock
• Process energy inputs such as utility invoices, meter records, etc.
• Ethanol production and sales volumes, adjusted to 60 degrees
Fahrenheit, such as meter records, contracts and sales invoices.
• Coproduct quantities and moisture content data such as
meter records, sales invoices.
• Full mass balance and yield analysis.
Separate distillers grains coproduct pathways are proposed, which would allow ethanol producers to account for different types of DGS produced, rather than using a composite pathway with the average make-up of DGS produced. Verification would include determining the split of energy use for the different types of DGS produced—the primary purpose of this change. READ MORE
