Marginal note:If using a CEMS

  •  (1) A responsible person who uses a CEMS must ensure compliance with the Reference Method.

  • Marginal note:Auditor’s report

Fuel-based Method

Marginal note:Quantification

 The quantity of CO2 emissions resulting from the combustion of fossil fuels in a unit in a calendar year, that is not measured using a CEMS, is determined by the formula

The formula for determining the quantity of CO2 emissions from the combustion of fossil fuels in a unit for a calendar year using a fuel-based method is Es plus the sum of Ei for each fossil fuel “i” combusted in the unit during the calendar year.

where

i
is the ith fossil fuel type that is combusted in the calendar year in a unit, where “i” goes from the number 1 to n and where n is the number of those fossil fuel types;
Ei
is the quantity of CO2 emissions that is attributable to the combustion of fossil fuels of type “i” in the unit in the calendar year, expressed in tonnes, as determined for that fuel type in accordance with section 18; and
Es
is the quantity of CO2 emissions that is released from the sorbent used to control the emission of sulphur dioxide from the unit in the calendar year, expressed in tonnes, as determined by the formula

S × R × (44/MMs)

where

S
is the quantity of sorbent material, such as calcium carbonate (CaCO3) , expressed in tonnes,
R
is the stoichiometric ratio, on a mole fraction basis, of CO2 released on usage of 1 mole of sorbent material, which is equal to 1 if the sorbent material is CaCO3, and
MMs
is the molecular mass of the sorbent material, which is equal to 100 if the sorbent material is CaCO3.

Marginal note:Measured carbon content

  •  (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,

      Vf × CCA × (MMA/MVcf) × 3.664 × 0.001

      where

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

      Vf × CCA × 3.664

      where

      Vf
      is the volume of the fuel combusted in the calendar year, determined using flow meters, expressed in kL , and
      CCA
      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 Vf, expressed in tonnes of carbon per kL of the fuel; and
    • (c) for a solid fuel,

      Mf × CCA × 3.664

      where

      Mf
      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
      CCA
      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 Mf, expressed in kg of carbon per kg of the fuel.
  • Marginal note:Weighted average

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

    The formula for determining the weighted average CCa is the quotient of the following two sums: the sum of the product resulting from the multiplication of Qi and CCi for each sampling period “i” and the sum of Qi for each sampling period “i”.

    where

    CCi
    is the carbon content of each sample or composite sample, as the case may be, of the fuel for the ith sampling period, expressed for gaseous fuels, liquid fuels and solid fuels, respectively, in the same unit of measure as that set out in CCA, 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:

  • Marginal note:Carbon content provided by the supplier

    (2) If the supplier of the fuel has provided the carbon content of the fuel, the responsible person can obtain from that supplier the carbon content of the fuel for the specified sampling period and at the specified minimum sampling frequency rather than taking samples in accordance with subsection (3).

  • Marginal note:Frequency

    (3) Each fuel sample must be taken at a time and location in the fuel handling system of the facility that provides the following representative samples of the fuel combusted at the applicable minimum frequency:

    • (a) for natural gas, during each sampling period consisting of each year that the unit generates electricity or produces useful thermal energy, two samples taken that year, with each of those samples being taken at least four months after any previous sample has been taken, in accordance with whichever of the following standard that applies:

      • (i) ASTM D4057-12, entitled Standard Practice for Manual Sampling of Petroleum and Petroleum Products,

      • (ii) ASTM D4177-16e1, entitled Standard Practice for Automatic Sampling of Petroleum and Petroleum Products,

    • (c) for a type of liquid fuel or of a gaseous fuel other than refinery gas and natural gas, during each sampling period consisting of each month that the unit generates electricity or produces useful thermal energy, one sample per month that is taken at least two weeks after any previous sample has been taken, in accordance with any of the standards referred to in paragraph (a); and

    • (d) for a solid fuel, one composite sample per month that consists of sub-samples, each having the same mass, that are taken from the fuel that is fed for combustion during each week that begins in that month and during which the unit generates electricity or produces useful thermal energy, and after all fuel treatment operations have been carried out but before any mixing of the fuel from which the sub-sample is taken with other fuels, and at least 72 hours after any previous sub-sample has been taken.

  • Marginal note:Additional samples

    (4) For greater certainty, the responsible person who, for the purposes of these Regulations, takes more samples than the minimum required under subsection (3) must make the determination referred to in subsection (1) based on each sample taken — and in the case of composite samples, each sub-sample taken — including those additional samples.

  • Marginal note:Significantly modified boiler units

    (5) In the case of a boiler unit referred to in subsection 3(4), one fuel sample is required for the initial performance test and each subsequent performance test and it must be taken in accordance with one of the applicable standards set out in subparagraphs (3)(a)(i) to (iv).
