GIMP 7 <br />Compost Program Design Considerations <br />Composting of vegetal materials is conducted using the windrow method. <br />Materials delivered to the MRF for composting are received on a paved area and are <br />cleaned. Non -vegetal and undesirable materials are removed. The feedstock is then <br />ground and formed into windrows that are roughly 300 feet long, ten feet wide and five <br />feet high at inception. Windrows are located on a cement pad designed to contain process <br />water for collection in a clay -lined pond. <br />The following odor minimizing considerations apply: <br />1. Aeration is achieved by turning the windrows a minimum of five times each <br />fifteen days. Turning is accomplished using a Scarab® turning machine. <br />2. Moisture content of the windrows is maintained by testing to insure adequate <br />levels are extant and moisture is added as needed <br />3. Feedstock is limited to vegetal materials suitable for composting <br />4. Airborne emissions monitored and controlled by adding moisture <br />5. Process water is collected through runoff into a clay -lined pond and is recirculated <br />for use in adding moisture <br />6. Personnel are instructed in machine operation and material inspection <br />7. In the event of extended electrical utility failure, a generator will be made <br />available to power water pumps as needed <br />8. All appropriate efforts will be made to minimize the affect of unusual weather <br />events. <br />
