The Off-road Compression-Ignition (Mobile and Stationary) and Large Spark-Ignition Engine Emission Regulations were recently published in the Canada Gazette, Part II. The Regulations is also available on the CEPA registry.
The purpose of the Regulations is to reduce smog caused by air pollutant emissions from large spark-ignition engines and stationary compression-ignition engines by establishing emission standards aligned with those of the United States (U.S.) Environmental Protection Agency (EPA). Specifically, the Regulations will introduce emission standards in alignment with the U.S. EPA’s Tier 2 standards for mobile large spark-ignition engines and the U.S. EPA’s Tier 4 standards for stationary compression-ignition engines. The Regulations will also provide flexibility in the form of less stringent Tier 2 or 3 standards for stationary compression-ignition engines destined for use in remote locations or as back-up or emergency sources of electricity. Emission standards for off-road mobile compression-ignition engines, as they exist in the Off-Road Compression-Ignition Engine Emission Regulations, are maintained in the Regulations.
What products would be subject to the Regulations?
The Regulations will apply to mobile compression-ignition (MCI) engines, large spark-ignition (LSI) engines, and stationary compression-ignition (SCI) engines that are imported into Canada or manufactured in Canada. MCI engines are typically found in machines used in agricultural, construction, forestry, and mining applications. LSI engines produce more than 19 kW (25 hp) of power and are commonly used in mobile off-road machines such as forklifts and ice resurfacers. SCI engines have a displacement of less than 30 litres per cylinder and are commonly used to provide electricity in remote communities, to drive fire pumps, as a back-up source of power for buildings, and to power irrigation systems, water pumps, compressors, etc.
The Regulations will come into force on June 4, 2021. The new standards will apply to LSI and SCI engines manufactured on or after that date. With regards to MCI engines, there are no changes to the standards in the Off-Road Compression-Ignition Engine Emission Regulations and MCI engines of the 2006 and later model years must meet the applicable emissions standards in place at their time of manufacture.
It should be noted that the current Off-Road Compression-Ignition Engine Emission Regulations continue to apply until the Regulations come into force.
Webinar invitation
We would like to invite you to a webinar, which will occur via Webex. The webinar will be offered in English on February 9, 2021 from 1:00pm – 2:30pm EST, and will be offered in French on February 11, 2021 from 1:00pm – 2:30pm EST. During this webinar, we will present an overview of the key changes that were made to the Regulations since the proposal was published in March 2019. The webinar will cover topics related to mobile diesel engines, large spark-ignition engines, and stationary diesel engines.
If you are interested in attending either of the webinars, please email by February 2, 2021 and indicate which session you would like to attend.
Please note that we will include an FAQ portion of the webinar. If you have any questions about the Regulations that you would like answered in the webinar, please submit those questions by email by February 2, 2021.
