Q103. How should inert wastes be accounted for in Equation HH-1?
A103. If a facility receives a segregated waste shipment that is known to contain only inert waste materials, the waste-specific values in Table HH-1 (‘waste composition option’), could be used for that shipment quantity, and the value of zero would be assigned for the DOC and k values for that waste quantity. Often inert waste (glass, plastics, metal, etc) is co-mingled with degradable waste in a waste shipment. The DOC and k values for bulk waste in Table HH-1 account for some volume of inert wastes in the bulk waste shipments, so it is generally appropriate to use the bulk waste DOC and k values for that shipment quantity. Please note that segregated inert waste quantities are considered to be included in Equation HH-1 even though they do not contribute to methane generation. Therefore, you must report these inert waste quantities, as required in §98.346(a).
