The facility is a Small, Type 3 Solid Waste Compost (SWC) Facility. It produces compost from the following feedstocks: animal manure, animal bedding, non-meat food waste, and yard waste. The following may also be added to the compost mix per the facility operations plan: paper, cardboard, and the compost site sediment basin dredged soil. 2. Material composted is received from the North Carolina Zoo. 3. The facility is not accessible to the public. It is operated weekdays from 7:00 am to 4:00 pm. 4. The facility permit and operations plan were discussed. 5. The compost created is used at the North Carolina Zoo in public areas and at animal exhibits. 6. Incoming material is stored in a pile until enough is obtained to create a windrow. A new windrow is generally formed monthly. 7. Material received is recorded in logbooks located at the compost site that correspond to where the material was obtained from on the property, as follows: Commissary, North Woods (North American exhibit area), Rocky Coast/Cypress Swamp (polar bear, seal, alligator, and mountain lion exhibit areas), Kids Zone, ZOG (zebra, ostrich, and giraffe exhibit areas), Elephant exhibit, Grasslands exhibit, Horticulture area, Sodexo (restaurants), the Arbor, and the Aviary. 8. The active compost area consists of small windrows. Commonly, there is one receiving pile and five or six windrows. 9. The windrows are rotated from the front of the active compost area to the rear when turned. 10. The windrow composting method requires that temperature data is recorded for at least 15 days maintained at > 131° F. The windrow shall be turned at least 5 times during the high temperature period. 11. Windrow temperatures are obtained soon after [windrow] construction. The temperatures are recorded throughout the high temperature period and continue to be recorded until 120° F is routinely attained. 12. The facility maintains windrow temperature records. Records were verified for windrow temperatures obtained during November 2015 and January 2016. The records document that the windrows were turned five times during the high temperature period. 13. The facility considers active composting to be complete in ~ 4 months. Cured compost is obtained in ~ 8 months or an additional 4 months. 14. Material to be cured is brought to the compost storage area located at the opposite side of the facility. Cured compost is stockpiled for ~ 6 months prior to use. 15. The facility annual report (FAR) was received by the SWS dated July 18, 2016. Material received for July 2015 through June 2016 is 1,809 tons. The amount of compost created is 535 tons, the amount used on site is 91 tons, and the amount stockpiled is 444 tons. 16. Compost shall be analyzed at intervals of every 20,000 tons or every six months, whichever comes first. 17. Manmade inerts testing was conducted on December 28, 2015 and June 30, 2016. 18. Metals concentration testing is conducted by the North Carolina Department of Agriculture & Consumer Services - Agronomic Services Division.
