emission factor for lime, measured in tonnes of emission of carbon dioxide per tonne of lime produced, as follows:
 (a) for commercial lime production—0.675;
 (b) for non‑commercial lime production—0.730;
 (c) for magnesian lime and dolomitic lime production—0.860.
 (2) In this section:
dolomitic lime is lime formed from limestone containing more than 35% magnesium carbonate.
magnesian lime is lime formed from limestone containing 5–35% magnesium carbonate.

4.14  Method 2—lime production
 (1) Method 2 is:

where:
Eij is the emissions of carbon dioxide (j) released from the production of lime (i) during the year, measured in CO2‑e tonnes.
Ai is the quantity of lime produced during the year, measured in tonnes and estimated under Division 4.2.5.
Alkd is the quantity of lime kiln dust lost as a result of the production of lime during the year, measured in tonnes and estimated under Division 4.2.5.
Flkd is:
 (a) the fraction of calcination achieved for lime kiln dust in the production of lime during the year; or
 (b) if the data in paragraph (a) is not available—the value 1.
EFij is worked out using the following formula:

          where:
          FCaO is the estimated fraction of lime that is calcium oxide derived from carbonate sources and produced from the operation of the facility.
          FMgO is the estimated fraction of lime that is magnesium oxide derived from carbonate sources and produced from the operation of the facility.
γ is the factor 1.861 × 10‑3 for converting a quantity of carbon dioxide from cubic metres at standard conditions of pressure and temperature to CO2‑e tonnes.
RCCSCO2 is carbon dioxide captured for permanent storage, measured in cubic metres in accordance with Division 1.2.3.
 (2) Method 2 requires lime to be sampled and analysed in accordance with sections 4.15 and 4.16.

4.15  General requirements for sampling
 (1) A sample of lime must be derived from a composite of amounts of the lime produced.
Note: Appropriate standards for sampling are:
 ASTM C25‑06, Standard Test Methods for Chemical Analysis of Limestone, Quicklime, and Hydrated Lime
 ASTM C50‑00 (2006), Standard Practice for Sampling, Sample Preparation, Packaging, and Marking of Lime and Limestone Products
 AS 4489.0–1997 Test methods for limes and limestones—General introduction and list of methods.
 (2) The samples must be collected on enough occasions to produce a representative sample.
 (3) The samples must also be free of bias so that any estimates are neither over nor under estimates of the true value.
 (4) Bias must be tested in accordance with an appropriate standard.
Note: An appropriate standard is AS 4264.4—1996 – Coal and coke – sampling – Determination of precision and bias.
 (5) The value obtained from the sample must only be used for the production period for which
