Removing Clarifying Language from the Proposed Phase 2 Medium- and Heavy-Duty Greenhouse Gas Standards

The final Phase 2 Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles will not contain clarifying language regarding modification for racing purposes.

EPA is committed to protecting public health by ensuring that cars driven on public roads meet pollution standards under the Clean Air Act. Congress required these standards for good reason: emissions from motor vehicles have been linked to premature death in people with heart or lung disease, aggravated asthma, decreased lung function, and increased respiratory problems.

And EPA supports motorsports and its contributions to the American economy and communities all across the country. EPA’s focus is not on vehicles built or used exclusively for racing, but on companies that don’t play by the rules and that make and sell products that disable pollution controls on motor vehicles used on public roads. These unlawful defeat devices pump dangerous and illegal pollution into the air we breathe.

The proposed language in the July 2015 proposal was never intended to represent any change in the law or in EPA’s policies or practices towards dedicated competition vehicles. Since our attempt to clarify led to confusion, EPA has decided to eliminate the proposed language from the final rule.

The Agency will continue to engage with the racing industry and others about ways to ensure that EPA supports racing and while maintaining the Agency’s focus where it has always been: reducing pollution from the cars and trucks that travel along America’s roadways and through our neighborhoods.

Proposed Rulemaking: Phase 2 Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles

The U.S. Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) are jointly proposing a national program that would establish the next phase of greenhouse gas (GHG) emissions and fuel efficiency standards for medium- and heavy-duty vehicles. This “Phase 2 program” would significantly reduce carbon emissions and improve the fuel efficiency of heavy-duty vehicles, helping to address the challenges of global climate change and energy security.

Notice of Data Availability

EPA and NHTSA have issued a Notice of Data Availability for the Heavy-Duty Greenhous Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles – Phase 2.

Comment Period Extended

EPA and NHTSA have extended the comment period to October 1, 2015.

Information on Public Hearings:
EPA and NHTSA jointly held a public hearing in Chicago, IL on Thursday, August 6, 2015, and a second hearing in Long Beach, CA on Tuesday, August 18, 2015.

Extending the Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles

EPA and NHTSA, in collaboration with the California ARB, plan to extend the Heavy-Duty National Program beyond model year 2018, to further reduce fuel consumption through the application of advanced cost-effective technologies and continue efforts to improve the efficiency of moving goods across the United States.

The complementary EPA and NHTSA standards that make up the Heavy-Duty National Program apply to combination tractors (semi trucks), heavy-duty pickup trucks and vans, and vocational vehicles (including buses and refuse or utility trucks). Together, these standards will cut greenhouse gas emissions and domestic oil use significantly. This program responds to President Obama’s 2010 request to jointly establish greenhouse gas emissions and fuel efficiency standards for the medium- and heavy-duty highway vehicle sector.
