In order to minimize the development of conditions that could lead to odor <br />problems, the compostable material handling areas of the site were designed <br />based on the nature and quantity of materials to be received and stored, <br />climatological factors, adjacent land use, grading, and drainage controls. <br />The primary sources of odors at this site occur during the hot dry summer <br />months. By composting the poultry manure the on-site odors should be reduced <br />since the waste storage ponds will not be receiving the bulk of the poultry <br />manure produced on-site; it will be going into compost. The initial mixing of the <br />poultry manure and the wood shavings will have the highest odors mainly due <br />to the fresh poultry manure. Once the compost process continues the odor will <br />be reduced. As a result, site personnel assess materials upon receipt for odor <br />generation potential. Site personnel have been trained to manage all <br />compostable material handling in a manner that minimizes the development of <br />conditions that could lead to objectionable odors. <br />MWE <br />The method of aeration that is being utilized is the "turned windrow method." <br />A windrow compost pile can be of any length. The height of windrows range <br />from 3 to 4 feet for dense materials with poor structures (e.g. manures). SKS <br />compost windrows are 3 feet high in height, 20 feet in width and 250 feet in <br />length. Windrow composting consists of placing the compostable materials in a <br />long narrow pile or windrow which are then agitated or turned on a regular <br />basis. The windrows aerate primarily by natural or passive air movements. The <br />rate of air exchange depends on the porosity of the windrow. <br />1 • • •, I • • <br />Fresh poultry manure has a moisture content of approximately 75%. This <br />manure is transported directly from the on-site houses to the on-site composting <br />facility. The purchased wood shavings received are from Stockton Wood <br />Shaving and they consist of virtually no moisture. The lack of moisture aids in <br />the minimization of odors as well as the composting process. The desired <br />moisture content in the compost windrow is about 50%. <br />7 <br />
