On July 3, 2024, Oregon Department of Environmental Quality Director Leah Feldon approved to delay implementation of the Heavy-Duty Low NOx Omnibus Rules for one year. The original Heavy-Duty Low NOx Omnibus Rules were adopted as part of the Clean Truck Rules<\/a> by the Environmental Quality Commission in November 2021. They require conventionally fueled heavy-duty vehicle and engine manufacturers to meet tougher NOx and particulate matter emission standards, overhaul engine testing procedures and further extend engine warranties to ensure NOx and PM emissions are reduced over the lifetime of each new vehicle and engine. The Omnibus Rules will now go into effect with engine model year 2025. This action makes permanent a similar temporary rule<\/a> the Environmental Quality Commission adopted on Nov. 16, 2023.<\/p>\n\n\n\n

Also, the new amendments include adoption of recent California updates<\/a> that provide additional compliance flexibility to engine manufacturers. They include allowing engine manufacturers to sell a larger volume of new federally certified internal combustion engines, referred to as \u201clegacy engines\u201d in the rule. As one of 17 states that has adopted California\u2019s new on-highway vehicle and engine emission standards, Oregon DEQ must periodically and routinely align its rules to remain identical to California\u2019s as required by the federal Clean Air Act<\/a>.<\/p>\n\n\n\n

The amendments went into effect on July 15, 2024.<\/p>\n\n\n\n
