Brandt Road <br /> --- -_ - . <br /> -Lodi,-CA, Site-Approval Number.:PA-0400365 <br /> Dear Mike, <br /> Per our conversation on February 10, 2006,the following letter presents an additional nitrogen <br /> loading estimate which includes composted chicken manure generated from the facility. You <br /> have requested this information in addition to the Soil Suitability and Nitrate Loading Study <br /> prepared by our office on December 23, 2005. The information presented in this letter is based <br /> on information discussed in the report and new information presented here. The calculation is <br /> also based on the following important assumptions: <br /> 1) Only six chicken houses are planned to be built by SKS Enterprises. The site plan <br /> calls for nine chicken houses to be built. The revised information was provided to <br /> our office by SKS Enterprises. <br /> 2) Initially, a maximum of 50 percent of the compost will be applied to land <br /> according to SKS Enterprises. Later, 100 percent of the compost will be hauled <br /> off site for sale. <br /> 3) The nitrogen content of the chicken manure/compost was obtained from the <br /> average of three poultry facilities tested by Washington State University in 1996 <br /> i <br /> (www.csanr.wsu.edu/resources/compost/Cc2.pdf). The nitrogen of the three <br /> varied significantly and actual nitrogen content may differ somewhat. <br /> r <br /> 4) Additional assumptions regarding the calculations are noted on the attached work <br /> sheet. <br /> The nitrogen loading estimate should be viewed as a gross, initial calculation to estimate the <br /> pounds of nitrogen which may be generated at the site from all the different uses. The sources of <br /> nitrogen include an initial 50 percent land application of compost, septic uses, and nitrogen from <br /> LODI ■ SACRAMENTO ■ MODESTO <br /> ENVIRONMENTAL DIVISION 902 Industrial Way,Lodi,California 95240 ■209.367.3701 ■ 209.369.422$fax ■www.noanderson.com <br /> k <br /> 6 <br />
