1. Agricultural Composting Operation - Agricultural composting operation means composting that takes place on a farm. Agricultural composting operation does not include an operation that involves nonorganic municipal solid waste or that composts municipal sludge, septage, industrial solid waste or industrial sludge. Agricultural composting operation does not include an operation that composts materials with a moderate or high risk of contamination from heavy metals, volatile and semi-volatile organic compounds, polychlorinated biphenyls or dioxin.

2. Agricultural Products - Agricultural products means those plants and animals and their products that are useful to humans and includes, but is not limited to, forages and sod crops, grains and feed crops, dairy and dairy products, poultry and poultry products, bees and bees' products, livestock and livestock products and fruits, berries, vegetables, flowers, seeds, grasses and other similar products, or any other plant, animal or plant or animal products that supply humans with food, feed, fiber or fur. Agricultural products does not include trees grown and harvested for forest products.

3. Air Curtain Incinerator- A portable or stationary combustion device that directs a plane of high velocity, forced air through a manifold head into a pit with vertical walls in such a manner as to maintain a curtain of air over the surface of the pit and a re-circulating motion of the air under the curtain. An air curtain incinerator is considered open burning.

4. Alkaline Hydrolysis- A process by which carcasses are treated in a vessel using high temperatures and pressure in a strong solution of sodium or potassium hydroxide.

6. Anaerobic Digestion- A process in which carcasses and other organic wastes are decomposed in a heated vessel in which there is no oxygen.

7. Animal Baiting Site - Locations at which offal, animal carcasses or other potential food sources are placed in order to attract wild animals. These are often used by coyote and bear hunters.

8. Animal Carcass(es)- Body(ies) or body parts of dead animals, including but not limited to pets, livestock and poultry. Carcasses may be mixed with manure and bedding or other organic materials which cannot be separated from the animal carcasses.

17. BPT- Best Practical (or Practicable) Treatment - A treatment technology or method that achieves the greatest reduction in pollution at a reasonable cost.

18. Burial - A process by which animal carcasses are disposed of by placement within an excavation into the soil or upon the soil surface where they are then covered by soil material.

19. Catastrophe (Catastrophic Event)- An unexpected occurrence or set of circumstances such as a fire, disease outbreak, flood or other disaster resulting in multiple animal carcasses demanding immediate action.

20. Commercial Composter (of carcasses or offal)- A business that receives and composts animal carcasses or offal from other farms, businesses or individuals.

21. Commissioner- Shall mean the Commissioner of the Department of Agriculture, Food and Rural Resources or his/her designee.

22. Compost Medium (pl Media)- The relatively dry bulky organic material that forms the matrix within which carcasses or offal are composted.

23. Composting- Composting is the natural biological degradation of plant and animal matter in a controlled, well aerated system. When oxygen, moisture, nitrogen and carbon are available in the right proportions, the degradation generates considerable quantities of heat, reaching temperatures of 130° to 170° F. This sustained high temperature is responsible for the virtually complete destruction of pathogenic organisms and weed seeds in the composted material. The process also results in a humus-like product that has its nutrients in a much more stable form than the uncomposted wastes making it safer and easier to store and use.

24. Composting, In-house - An emergency carcass disposal technique in which compost windrows are formed within the building(s) that housed the animals to be composted. This generally applies to poultry that are raised in open floor buildings on litter.

25. Composting, In-vessel - Compost systems that incorporate some type of vessel. Most of these systems use some form of active aeration to provide the needed oxygen. One system that has been used to compost poultry mortalities from an avian influenza outbreak utilized the large plastic 'bags' designed for feed storage with aeration tubes inside. Most of these systems are best suited to small carcasses or carcasses that have been ground or cut into pieces that can be managed by the system.

26. Composting, Precondition and Turn Method - A composting system that was developed specifically for disposal of animal carcasses and slaughterhouse wastes. In this method, the carcass or body parts are placed between layers of dry absorbent bedding or other compost media. The carcasses or body parts are then allowed to decompose without disturbance for a period of time, which varies with carcass size and other factors. Once this pre-conditioning period is done, the pile or windrow is then turned similar to the turned windrow system. This method may be used for both routine and emergency situations and for both large and small carcasses and slaughterhouse wastes (offal) of all types.

27. Composting,Static Pile - The static pile method of composting uses a pile of compostable material that is not agitated or turned. The initial mixing of the carcasses with the bulking agent must be sufficient to allow proper air flow and effective composting. Aerobic conditions are maintained by natural ventilation of the pile that is enhanced by using materials that maintain relatively high pile porosity. This approach applies primarily to poultry and other small carcasses.

28. Composting, Static Pile (Aerated) - In the aerated static pile method (also known as the Beltsville Method or Rutgers Method), the compost is not agitated or turned. The initial mixing of the carcasses with the bulking agent must be sufficient to allow proper air flow and effective composting. Aerobic conditions are maintained by mechanically drawing, or blowing air through the pile. This approach applies primarily to poultry and other small carcasses.

29. Composting, Turned Windrow - The turned windrow method is a compost system, in which the compost mixture is placed in rows and turned periodically during the compost cycle. The turning action supplies oxygen through gas exchange, thereby creating natural ventilation. This system only applies to small carcasses, small body parts or ground carcasses.

30. Composting,University of Maryland Bin Composting System- A composting system developed by the University of Maryland and the Delaware Cooperative Extension for disposing of the routine mortality from commercial broiler operations.This system utilizes covered bins and only applies to small or medium size carcasses or small body parts.

31. Contained Facilities- Structures built to house compost or curing piles thatinclude impervious surfaces and are covered so as to exclude precipitation.

77. Thermal Hydrolysis - A process in which ground carcasses or other organic material are heated to 180°C using saturated steam for 40 minutes or more while under high pressure (10 bar or higher). Early research into this technology suggests that prions may be deactivated in this process.

78. Transmissible Spongiform Encephalopathy (TSE) - One of several similar neurologic diseases thought to be caused by a mis-folded protein (prion) in the nervous tissue which results in slow degeneration of the nervous system and ultimately in death. These diseases include Scrapie, 'Mad Cow Disease' and Chronic Wasting Disease.
