 (5) Paragraph (3)(b) only applies if:
 (a) the change in the stockpile of the fuel for the facility for the year is less than 1% of total consumption on average for the facility during the year; and
 (b) the stockpile of the fuel for the facility at the beginning of the year is less than 5% of total consumption of the fuel from the operation of the facility during the year.

2.32  Volumetric measurement—all natural gases
 (1) For subparagraph 2.31(2)(a)(i) and (ii), volumetric measurement must be calculated at standard conditions and expressed in cubic metres.
 (2) The volumetric measurement must be calculated using a flow computer that measures and analyses the following at the delivery location of the gaseous fuel:
 (a) flow;
 (b) relative density;
 (c) gas composition.
 (3) The volumetric flow rate must be:
 (a) continuously recorded; and
 (b) continuously integrated using an integration device.
 (3A) The integration device must be isolated from the flow computer in such a way that, if the computer fails, the integration device will retain:
 (a) the last reading that was on the computer immediately before the failure; or
 (b) the previously stored information that was on the computer immediately before the failure.
 (4) All measurements, calculations and procedures used in determining volume (except for any correction for deviation from the ideal gas law) must be made in accordance with:
 (a) the instructions mentioned in subsection (5); or
 (b) an appropriate internationally recognised standard or code.
Note: An example of an internationally recognised equivalent standard is New Zealand standard NZS 5259:2004.
 (5) For paragraph (4)(a), the instructions are those mentioned in:
 (a) for orifice plate measuring systems:
 (i) the publication entitled AGA Report No. 3, Orifice Metering of Natural Gas and Other Related Hydrocarbon Fluids Part 3: Natural Gas Applications, published by the American Gas Association in August 1992; or
 (ii) Parts 1 to 4 of the publication entitled ANSI/API MPMS Chapter 14.3 Part 2 (R2011) Natural Gas Fluids Measurement: Concentric, Square‑Edged Orifice Meters ‑ Part 2: Specification and Installation Requirements, 4th edition, published by the American Petroleum Institute on 30 April 2000;
 (b) for turbine measuring systems—the publication entitled AGA Report No. 7, Measurement of Natural Gas by Turbine Meter (2006), published by the American Gas Association on 1 January 2006;
 (c) for positive displacement measuring systems—the publication entitled ANSI B109.3—2000, Rotary Type Gas Displacement Meters, published by the American Gas Association on 13 April 2000.
 (6) Measurements must comply with Australian legal units of measurement.
 (7) Standard conditions means, as measured on a dry gas basis:
 (a) air pressure of 101.325 kilopascals; and
 (b) air temperature of 15.0
