Off-road Compression-Ignition (Mobile and Stationary) and Large Spark-Ignition Engine Emission Regulations — 25
Standards 25 (1) Despite sections 10 to 23 and subject to subsection (2), a replacement engine must, instead of conforming to the applicable standards referred to in those sections, conform to (a) if a replacement engine exists that is manufactured to the specifications, in respect of the control of emissions, of a model year subsequent to the model year of the original engine and that has the physical or performance characteristics necessary for the operation of the machine, the most stringent of the following: (i) the standards referred to in paragraph 10(1)(a) or (b) or subsection 11.1(2) of the Off-Road Compression-Ignition Engine Emission Regulations , as they read immediately before the coming into force of these Regulations, that are applicable to an engine manufactured to the specifications of that subsequent model year, (ii) if a replacement engine exists that conforms to standards that are applicable to a model year that is subsequent to the model year referred to in subparagraph (i), those standards, or (iii) if none of the standards referred to in subparagraph (i) or (ii) are applicable, the manufacturer’s specifications in respect of the control of emissions, if those specifications are at least as stringent as the specifications of the model year of the original engine; and (b) if no replacement engine exists that is manufactured to the specifications, in respect of the control of emissions, of a model year subsequent to the model year of the original engine and that has the physical or performance characteristics necessary for the operation of the machine, the most stringent of the following: (i) the standards referred to in paragraph 10(1)(a) or (b) or subsection 11.1(2) or 13(2) of the Off-Road Compression-Ignition Engine Emission Regulations , as they read immediately before the coming into force of these Regulations, that are applicable to the original engine, (ii) if a replacement engine exists that has the physical or performance characteristics necessary for the operation of the machine and conforms to standards that are applicable to the model year of the original engine and are more stringent than those referred to in subparagraph (i), those more stringent standards, or (iii) if none of the standards referred to in subparagraph (i) or (ii) are applicable, the manufacturer’s specifications in respect of the control of emissions, if those specifications are at least as stringent as the specifications of the model year of the original engine. References to CFR (2) For the purposes of subparagraphs (1)(a)(i) and (1)(b)(i), a reference in the Off-Road Compression-Ignition Engine Emission Regulations to a provision of the CFR is to be read as a reference to that provision as it read immediately before the day on which these Regulations come into force. Interpretation (3) For the purposes of subparagraph (1)(b)(i), the reference to subsection 13(2) of the Off-Road Compression-Ignition Engine Emission Regulations must be read as excluding the dates mentioned in that subsection. Limitation (4) An engine is a replacement engine only if it was manufactured to replace the engine of a machine that is located in Canada and that, on the day that the replacement engine is installed, had its manufacture completed (a) in the case of a machine in or on which a mobile engine is installed, 40 years ago or less; or (b) in the case of a machine in or on which a stationary engine is installed, less than 15 years ago.
