Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations — 23
Measured carbon content 23 (1) Subject to section 24 , the quantity of CO 2 emissions attributable to the combustion of a fuel in a unit during a calendar year, expressed in tonnes, is determined in accordance with the applicable formula, as follows: (a) for a solid fuel M f × CC A × 3.664 where M f is the mass of the fuel combusted during the calendar year as determined, as the case may be, on a wet or dry basis, expressed in tonnes and measured by a measuring device, and CC A is the weighted average, expressed in kg of carbon per kg of the fuel, of the carbon content of the fuel determined in accordance with subsection (2) on the same wet or dry basis as the one used in the determination of M f ; (b) for a liquid fuel V f × CC A × 3.664 where V f is the volume of the fuel combusted during the calendar year, expressed in kL, determined by using flow meters, and CC A is the weighted average, expressed in tonnes of carbon per kL of the fuel, of the carbon content of the fuel determined in accordance with subsection (2) at the same temperature as the one used in the determination of V f ; and (c) for a gaseous fuel The formula for determining the quantity of CO2 emissions attributable to a gaseous fuel is the product resulting from the multiplication of Vf, CCa, the constants of 3.664, the constant 0.001, and the quotient of MMa over MVcf. where V f is the volume of the fuel combusted during the calendar year, expressed in standard m 3 , determined by using flow meters, CC A is the weighted average, expressed in kg of carbon per kg of the fuel, of the carbon content of the fuel determined in accordance with subsection (2), MM A is the average molecular mass of the fuel, expressed in kg per kg-mole of the fuel, determined based on fuel samples collected in accordance with section 27 , and MV cf is the molar volume conversion factor, namely 23.645 standard m 3 per kg-mole of the fuel at standard conditions of 15°C and 101.325 kPa. Weighted average (2) The weighted average referred to in paragraphs (1)(a) to (c) as CC A is, based on fuel samples collected in accordance with section 27 , to be determined in accordance with the following 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 CC i is the carbon content of, as the case may be, the composite sample, or the sample, of the fuel for the i th sampling period expressed for solid fuels, liquid fuels and gaseous fuels, respectively, in the same unit of measure as the one set out in CC A , as provided by the supplier of the fuel to the responsible person and, if not so provided, as determined by the responsible person, and measured (a) for a solid fuel, on the same wet or dry basis as the one used in the determination of CC A , in accordance with, (i) for coal, biomass or solid fuel derived from waste, ASTM D5373 - 08, entitled Standard Test Methods for Instrumental Determination of Carbon, Hydrogen, and Nitrogen in Laboratory Samples of Coal , and (ii) for any other solid fuel, (A) an applicable ASTM standard for the measurement of the carbon content of the fuel, and (B) if no such ASTM standard applies, an applicable internationally recognized method for the measurement of the carbon content of the fuel, (b) for a liquid fuel, in accordance with any of the following standards or methods that applies for the measurement of the carbon content of the fuel: (i) ASTM D3238 - 95(2010), entitled Standard Test Method for Calculation of Carbon Distribution and Structural Group Analysis of Petroleum Oils by the n-d-M Method , along with either of the following applicable ASTM standards: (A) ASTM D2503 - 92(2007), entitled Standard Test Method for Relative Molecular Mass (Molecular Weight) of Hydrocarbons by Thermoelectric Measurement of Vapor Pressure , and (B) ASTM D2502 - 04(2009), e
