Active compost is generating temperatures of at least 50 degrees <br /> Celsius (122 degrees Fahrenheit) during decomposition; or is releasing carbon dioxide at a rate <br /> of at least 15 milligrams per gram of compost per day, or the equivalent of oxygen uptake. <br /> (2) "Additives" means material mixed with feedstock or active compost in order to adjust the <br /> moisture level, carbon to nitrogen ratio, or porosity to create a favorable condition. Additives <br /> include, but are not limited to, fertilizers and urea.

Amendments do not include septage, biosolids, or compost feedstock. <br /> (8) "Anaerobic Decomposition" means the biological decomposition of organic substances in the <br /> absence of oxygen. <br /> (9) "Biosolids" means solid, semi-solid, or liquid residue generated during the treatment of <br /> domestic sewage in a treatment works. Biosolids includes, but is not limited to, treated domestic <br /> septage and scum or solids removed in primary, secondary, or advanced wastewater treatment <br /> processes.
