George Tyson, President <br /> Food and Energy Breakthru Inc . <br /> 6400 Monona Drive <br /> Madison, WI 53716 <br /> SUBJECT: Proposed Deerfield Plant <br /> Liquid By-Product Disposal <br /> Dear Mr. Tyson: <br /> On June 9, 1987 I received a copy of a report on the analysis of liquid by-product <br /> material which is to be generated at the proposed Deerfield facility. The analysis <br /> was performed partly by the U.W. Soil and Plant Analysis Laboratory and partly by <br /> Strand Associates Inc . both located in Madison. ' <br /> Based on this one analysis and assuming this one analysis is representative of the <br /> material to be generated at the Deerfield facility, it appears the by-product <br /> material is biodegradable and can be applied to land based on its nutrient value. <br /> It also appears that the limiting constituent for controlling the rate of <br /> application to land sites is potassium. Reported potassium content of the material <br /> was 1 .07% which converts to 264 pounds of K20 per 1 ,000 gallons of material . <br /> Assuming a high potassium demanding crop such as alfalfa, the recommended annual <br /> application of this material should not be greater than 2,000 gallons per acre per <br /> year. The resulting nitrogen content at this annual rate is 45 pounds of nitrogen <br /> per acre while the phosphorus content is 28 pounds of P2 Os per acre. <br /> At the 2000 gallon per acre per year rates the reported heavy metal and cation <br /> loadings to the soil will be very low. Anticipated land area required for disposal <br /> of this material can be estimated based on a daily generation of 13,000 gallons per <br /> day of by-product material and assuming it is generated 365 days per year. The <br /> required area for disposal amounts to 2 ,372 acres . Please understand that this area <br /> requirement could be significantly reduced if the daily generation of 13,000 gallons <br /> per day is reduced or if future potassium analyses are less than the one reported. <br /> I will begin drafting a proposed Wisconsin Pollutant Discharge Elimination System <br /> WPDES discharge permit for your facility when we receive a completed application. <br /> If you have any additional questions please call me at (608)267-7644. <br /> Sincerely, <br /> �.,,' <br /> David K.
