E :.V I • E The method of aeration that is being utilized is the "turned/ churned method". A pile of compost can be of almost any length. The height of pile will range from 3 to 4 feet for dense materials with poor structures like poultry manure. S.K.S.'s compost rows are approximately 3 feet in height, 20 feet in width, and 250 feet in length. Windrow composting consists of placing the compostable materials in a long narrow pile or windrow which is between two concrete stem walls. The compost is agitated or turned on a regular basis. Every day when new manure and wood shavings are added the pile is mixed and moves 7 feet. The windrow is aerated primarily by natural or passive air movement. The rate of air exchange depends on the porosity of the windrow. MOISTURE CONTENT OF MATERIALS AND MOISTURE MANAGEMENT Fresh poultry manure has a moisture content of approximately 75%. This manure is transported directly from the on-site Honen's to the on-site composting facility. The wood shavings consist of virtually no moisture. The lack of moisture in the wood product aids in quick absorption of moisture from the manure, minimizing of odor and increasing the composting process. The desired moisture content in the compost windrow is about 50%. FEEDSTOCK CHARACTERISTICS AND QUALITY Currently the feedstock consists of fresh poultry manure and fresh wood shavings. The poultry manure utilized in the compost is produced fresh daily on-site. The birds are fed a consistent balanced ration, therefore the poultry manure will always be of a consistent product. Wood shavings are delivered fresh approximately every two weeks. Wood shavings are inspected for odors or defects such as mold and/or any other noticeable visual abnormalities. All loads of wood shavings will be visually checked for any physical contaminants. Any unacceptable materials will either be removed or sent back to the destination of origin. If the wood shavings become contaminated prior to composting, they will be removed and disposed of in an appropriate manner. The approved and permissible site of disposal will be selected according to the contaminants and/or unacceptable material found in the wood chips. A record of every load received and the results of the inspection will be documented. If other feedstocks are utilized in the compost Swan Joaquin County Environmental Health department will be notified.
