Regulations Limiting Carbon Dioxide Emissions from Natural Gas-fired Generation of Electricity (SOR/2018-261)

Marginal note:Measured carbon content

• 18 (1) The quantity of CO₂ emissions, that is attributable to the combustion of a fossil fuel in a unit in a calendar year is determined by one of the following formulas, whichever applies:

  • (a) for a gaseous fuel,

    V_f × CC_A × (MM_A/MV_cf) × 3.664 × 0.001

    where

    V_f

    is the volume of the fuel combusted in the calendar year, determined using flow meters, expressed in standard m³,

    CC_A

    is the weighted average of the carbon content of the fuel, determined in accordance with subsection (2), expressed in kg of carbon per kg of the fuel,

    MM_A

    is the average molecular mass of the fuel, determined based on fuel samples taken in accordance with section 19, expressed in kg per kg-mole of the fuel, and

    MV_cf

    is the molar volume conversion factor of 23.645 standard m³ per kg-mole of the fuel at standard conditions;

  • (b) for a liquid fuel,

    V_f × CC_A × 3.664

    where

    V_f

    is the volume of the fuel combusted in the calendar year, determined using flow meters, expressed in kL , and

    CC_A

    is the weighted average of the carbon content of the fuel, determined in accordance with subsection (2), at the same temperature as that used in the determination of V_f, expressed in tonnes of carbon per kL of the fuel; and

  • (c) for a solid fuel,

    M_f × CC_A × 3.664

    where

    M_f

    is the mass of the fuel combusted in the calendar year, determined, as the case may be, on a wet or dry basis using a measuring device, expressed in tonnes, and

    CC_A

    is the weighted average of the carbon content of the fuel, determined in accordance with subsection (2), on the same wet or dry basis as that used in the determination of M_f, expressed in kg of carbon per kg of the fuel.

• Marginal note:Weighted average

  (2) The weighted average “CC_A” referred to in paragraphs (1)(a) to (c) is determined by the formula

  

  where

  CC_i

  is the carbon content of each sample or composite sample, as the case may be, of the fuel for the i^th sampling period, expressed for gaseous fuels, liquid fuels and solid fuels, respectively, in the same unit of measure as that set out in CC_A, as provided by the supplier of the fuel to the responsible person or, if not so provided, as determined by the responsible person in the following manner:

  • (a) for a gaseous fuel,

    • (i) in accordance with whichever of the following standards for the measurement of the carbon content of the fuel that applies:

      • (A) ASTM D1945-14, entitled Standard Test Method for Analysis of Natural Gas by Gas Chromatography,

      • (B) ASTM UOP539-12, entitled Refinery Gas Analysis by Gas Chromatography,

      • (C) ASTM D7833-14, entitled Standard Test Method for Determination of Hydrocarbons and Non-Hydrocarbon Gases in Gaseous Mixtures by Gas Chromatography, and

      • (D) API Technical Report 2572, 1st edition, published in May 2013 and entitled Carbon Content, Sampling, and Calculation, or

    • (ii) by means of a direct measuring device that measures the carbon content of the fuel,

  • (b) for a liquid fuel, in accordance with whichever of the following standards or methods for the measurement of the carbon content of the fuel that applies:

    • (i) API Technical Report 2572, 1st edition, published in May 2013 and entitled Carbon Content, Sampling, and Calculation,

    • (ii) ASTM D5291-16, entitled Standard Test Methods for Instrumental Determination of Carbon, Hydrogen, and Nitrogen in Petroleum Products and Lubricants,

    • (iii) the ASTM standard that applies to the type of fuel, or

    • (iv) if no ASTM standard applies, an applicable internationally recognized method, and

  • (c) for a solid fuel, on the same wet or dry basis as that used in the determination of CC_A, in accordance with,

    • (i) for a solid fuel derived from waste, ASTM E777-08, entitled Standard Test Method for Carbon and Hydrogen in the Analysis Sample of Refuse-Derived Fuel, and

    • (ii) for any other solid fuel, the following standard or method for the measurement of the carbon content of the fuel:

      • (A) the ASTM standard that applies to the type of fuel, and

      • (B) if no ASTM standard applies, an applicable internationally recognized method;

  i

  is the i^th sampling period that is referred to in section 19, where “i” goes from the number 1 to n and where n is the number of those sampling periods; and

  Q_i

  is the volume or mass, as the case may be, of the fuel combusted during the i^th sampling period, expressed

  • (a) in standard m³, for a gaseous fuel,

  • (b) in kL, for a liquid fuel, and

  • (c) in tonnes, for a solid fuel, on the same wet or dry basis as that used in the determination of CC_A.
