ATTACHMENT -" <br /> Project Description—Microgy/Lodi Feed Systems, LLC <br /> Microgy/Lodi Feed Systems, LLC intends to construct and operate an anaerobic <br /> digester and a paddle dryer to dry animal feed on the de Snayer Dairy (the"Dairy") <br /> located at 23243 North Rond Road, Lodi, CA 95242. The digester will digest dairy cow <br /> manure from the Dairy's operation to produce biogas (60-70% methane and 30-40% <br /> carbon dioxide). The dryer will combust the biogas to dehydrate one or more agricultural <br /> products to form an animal feed supplement. <br /> Anaerobic digestion is a biological process where microorganisms- in the <br /> absence of oxygen - convert organic compounds to methane, carbon dioxide, cellular <br /> materials, and other compounds. The liquid effluent of the process is a biologically <br /> stable effluent with reduced organic nitrogen compounds and BOD, thus reducing the <br /> potential for ground and surface water contamination. <br /> Microgy Cogeneration Systems, Inc. ("Microgy") will construct and operate the <br /> digester. At the heart of the Microgy System is the enhanced anaerobic digester system <br /> developed over the past 15 years by Microgy's partner in Denmark. Microgy's Danish <br /> partner currently has over 28 similar plants operating throughout Europe. The system co- <br /> digests certain agricultural organic byproducts with the manure ("substrates")to enhance <br /> the biological activity and to create significantly more biogas than other anaerobic <br /> digestion technologies currently on the U.S. market. <br /> The Microgy system is comprised of the following main components: a mix tank <br /> that holds three to five days of manure; an above-ground, welded steel digester; a <br /> substrate tank; dual-fuel water heater; biogas flare; and a pump and control ("PLC") <br /> module. The PLC control system incorporates many safety features and will be <br /> monitored locally as well as remotely by Microgy and Danish engineers. <br /> The general environmental benefits of anaerobically digesting manure and other <br /> organic byproducts are well documented by the US and European experiences. Those <br /> benefits can be separated into benefits to the general public and benefits to the farm. <br /> Benefits to the public include: reduced BOD/COD of organic slurry; odor reduction; <br /> pathogen reduction; reduced greenhouse gas emissions; and reduced energy demand to <br /> produce commercial fertilizers. Benefits to the farm include: nutrients (esp. nitrogen) are <br /> more available for plant uptake; fertilizer value of nitrogen is more predictable than <br /> organically bound nitrogen; reduced use/cost of mineral (commercial) fertilizer; weed <br /> seeds destroyed–reduced pesticide use; and reduction of phytotoxic substances. <br /> The dryer is a tubular paddle dryer that combusts the biogas to produce a hot, dry <br /> process air stream. Within the dryer three several discreet zones created by internal air <br /> dams and adjustable paddles. The Inlet Zone achieves size reduction and the majority of <br /> the moisture evaporation by creating a highly turbulent and efficient mixing environment. <br /> The purpose of the Retention Zone is to ensure the product remains in the dryer long <br /> enough to achieve the desired drying action. The Discharge Zone achieves additional <br /> retention and drying, but its paddles are oriented to discharge the product. <br /> ATTACHMENT <br /> Project Description—Microgy/Lodi Feed Systems, LLC <br /> Typical materials that will enter the dryer may include whey permeate and other <br /> dairy solids, sugar beet byproducts, potato residuals, and other grain byproducts that may <br /> otherwise have to be land-applied for disposal currently. Final products are appropriate <br /> for animal feed. Their energy and nutrient values will depend on the entering materials, <br /> and may be appropriate for beef cattle, dairy cows, swine, poultry and/or specialty pet <br /> food. The Scoular Company is responsible for sourcing the feed inputs and marketing <br /> the feed products. <br /> 2 <br />
