1.19GA  Volume of greenhouse gas stream—criterion BBB
  For subparagraph 1.19E(2)(b)(ii), criterion BBB is the estimation of the volume of the captured greenhouse gas stream from the operation of the facility during a year measured in accordance with industry practice, if the equipment used to measure the volume of the captured greenhouse gas stream does not meet the requirements of criterion AAA.
Note: An estimate obtained using industry practice must be considered with the principles in section 1.13.

1.19H  Volumetric measurement—compressed greenhouse gas stream
 (1) For subparagraph 1.19G(2)(a)(i), volumetric measurement of a compressed greenhouse gas stream must be in cubic metres at standard conditions.
 (1A) For this section and subparagraph 1.19G(2)(a)(i), a compressed greenhouse gas stream does not include either of the following:
 (a) a super‑compressed greenhouse gas stream;
 (b) a greenhouse gas stream that is compressed to a super‑critical state.
 (2) The volumetric measurement is to be calculated using a flow computer that measures and analyses flow signals and relative density:
 (a) if the greenhouse gas stream is captured by the relevant person and is neither transferred to the relevant person nor transferred by the relevant person to another person—at the point of capture of the greenhouse gas stream; or
 (b) if the greenhouse gas stream is transferred to a relevant person—at the point of transfer of the greenhouse gas stream.
 (3) The volumetric flow rate must be continuously recorded and integrated using an integration device that is isolated from the flow computer in such a way that if the computer fails, the integration device will retain the last reading, or the previously stored information, that was on the computer immediately before the failure.
 (4) Subject to subsection (5), 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 the instructions contained in the following:
 (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
