Regulations Limiting Carbon Dioxide Emissions from Natural Gas-fired Generation of Electricity — 18
Measured carbon content 18 (1) The quantity of CO 2 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 m 3 , 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 m 3 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. Weighted average (2) The weighted average “CC A ” 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 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-Derive
