EPA Provides Updates on Emissions Standards, SmartWay Activities

The U.S. Environmental Protection Agency expects to issue a notice of proposed rulemaking later this year aimed at establishing new emissions standards for oxides of nitrogen (NOx) and other pollutants for highway heavy-duty engines, an EPA official told the S.11 study group of the Technology & Maintenance Council of American Trucking Associations during TMC’s virtual spring meeting.

Low rolling resistance tires are a key element of the SmartWay program. Dennis Johnson, director of EPA’s Technology Assessment Center says SmartWay is looking at the industry procedures for testing tire rolling resistance and making sure the procedures are repeatable enough. “Our intention is to circulate to the retread industry, the tire industry, these updated protocols, probably within a month,” Johnson said. “So over the next six months, we will be trying to finalize them.”
