5.13  Opening stock of degradable organic carbon for the first reporting period
 (1) For paragraph 5.4A(d), the amount of opening stock of degradable organic carbon at the landfill at the start of the first reporting period for the landfill must be estimated in accordance with subsection 5.4(4):
 (a) by using the details of the total tonnage of solid waste (broken down into waste stream and waste mix type and estimated in accordance with section 5.5) disposed of in the landfill each year over the lifetime of the landfill until the start of the first reporting period for the landfill; or
 (b) if the operator of a landfill is unable to comply with paragraph (a)—by using the following information in relation to the landfill:
 (i) the number of years that the landfill has been in operation;
 (ii) the estimated annual tonnage of solid waste disposed of in the landfill over the lifetime of the landfill until the start of the first reporting period for the landfill, worked out in accordance with subsection (2);
 (iii) the State or Territory in which the landfill is located.
 (2) For subparagraph (1)(b)(ii), the estimated annual tonnage of waste is to be worked out:
 (a) by using the average annual tonnage of solid waste disposed of in the landfill for the years for which data is available; or
 (b) by conducting a volumetric survey of the landfill in accordance with subsections (3) and (4); or
 (c) by using industry estimation practices (such as the use of accepted industry weighbridges, receipts, invoices, other documents or records or population and per‑capita waste generation rates).
 (3) For paragraph (2)(b), the survey:
 (a) must be a ground‑based survey or an aerial survey; and
 (b) must be conducted by a qualified surveyor.
 (4) For the volumetric survey, the volume of waste is to be converted to mass by using one of the following volume‑to‑mass conversion factors:
 (a) the landfill volume‑to‑mass conversion factors that were used during the most recent reporting year in order to comply with a landfill reporting requirement of the State or Territory in which the landfill is located;
 (b) if the factors mentioned in paragraph (a) were not used during the most recent reporting year in order to comply with a landfill reporting requirement of the State or Territory in which the landfill is located—the volume‑to‑mass conversion factors specified in column 3 of an item in the following table for a waste stream specified in column 2 of the item.
