A descendant of German and Norwegian immigrants that settled in Iowa between 1850 and 1873, Bryan Sievers, and his wife Lisa, are the current generation of owners and operators of the Sievers’ farm. Bryan is an enthusiastic environmental steward of the land and takes pride in using all available resources, including the air, land, water, and sun for their highest and best use. The Sievers’ 2,300-acre farming operation, 2,400 head beef cattle feedlot, and renewable energy facility is located in western Scott County, Iowa near Stockton.

In 2009, this philosophy became the motivation behind implementing the combined heat and power (CHP) anaerobic digester project. The Sievers were looking to dramatically expand the farm’s beef cattle feedlot but had concerns about any of the expansion’s effects on their carbon footprint, water quality, soil health, and the environment. The solution was a 1 MW CHP system fueled by the methane produced from two 970,000 gallon anaerobic digesters utilizing beef cattle manure, agricultural processing waste streams, cover crops, and other co-feeds.

AgriReNew, a company created by the Sievers and their partners, Dr. William and Judy Davidson, commissioned their digesters and CHP power plant in 2013. Today, the digesters process over 55,000 gallons per day of cattle manure and other off-site co-feeds in the complete-mix system. The electricity that’s generated, 24 hours per day 7 days per week, is sold to their local service provider, Interstate Power and Light (Alliant Energy).

In 2014, AgriReNew received the Agricultural Biogas Project of the Year Award from the American Biogas Council and received the 2014 Iowa Environmental Excellence Award for their anaerobic digester project.

Nathalie Hoffman has been advising clients on matters related to the LCFS since it first went into effect in 2011.

When the regulation underwent a major amendment in 2018, it added validation and verification functions required to be performed by professionals certified as LCFS verifiers. Nathalie became certified by CARB as such a verifier in 2020, in the first class ever.

The amended LCFS also included substantial new requirements for companies with existing certified fuel pathways and those wishing to get their pathways certified. Nathalie realized these companies would need assistance navigating the amended regulation and she founded LCFS Consulting Services, Inc. to provide that assistance.

While LCFS Consulting assists producers of traditional liquid biofuels like ethanol, biodiesel and renewable diesel, it specializes in RNG and innovative fuel pathways. Nathalie therefore joined the ABC and now serves as Co-Chair of the Agriculture Committee where she is working with others to expand the categories of livestock manure that can obtain an ultra-low carbon intensity score under the LCFS.

Typical projects for LCFS Consulting include determining the estimated CI of a proposed fuel pathway and advising project sponsors on ways to potentially lower it, preparing estimated CI reports for alternative fuel producers, their investors and bankers, assisting with the fuel pathway application process, including interface with appropriate CARB staff, creating the required monitoring plans and assisting in the preparation of the required quarterly and annual reports after certification.

Nathalie also understands alternative fuel production from the point of view of a project developer. With a background as a lawyer representing banks for project finance deals, she was the CEO of a company developing a utility-scale biorefinery in California’s Imperial Valley. The feedstock was locally-grown agricultural biomass.

Her educational background includes an undergraduate BS degree in Mathematics from the University of Michigan, a JD degree from UCLA School of Law and an MBA from UCLA’s Anderson School of Management. Nathalie is a member in good standing of the California Bar.

She’s located in Los Angeles, CA, with easy access to CARB in Sacramento.
