Diesel Engine Regulations

Do you meet current diesel engine regulations?

The Environmental Protection Agency (EPA) has identified reducing emissions from diesel engines as one of the most important air quality challenges facing the United States today.

According to a March 2014 EPA report, over 149 million Americans currently experience unhealthy levels of air pollutants which are linked to adverse health impacts such as hospital admissions, emergency room visits and premature mortality.

The World Health Organization estimates exposure to particulate matter (PM) less than 2.5 micrometers in diameter (PM2.5) claims an average of 8.6 months from the life of every person in Europe.

To address these issues, policies implemented in major markets across the globe have significantly reduced diesel emissions relative to prior regulations. Increased regulations are expected to further reduce emissions levels.

U.S. diesel emission reduction strategies drive the market.

The EPA has established the National Clean Diesel Campaign in order to promote diesel emission reduction strategies. This campaign oversees regulatory programs for new diesel engines and other innovative programs for the millions of diesel engines already in use.

In the United States, heavy duty diesel retrofits have been driven primarily by subsidy programs supported under the Diesel Emissions Reduction Act, or DERA, the American Recovery and Reconstruction Act, or ARRA, Proposition 1B in California, the U.S. Department of Transportation's Congestion Mitigation and Air Quality Improvement program, or CMAQ, and other state and local programs.

California emissions standards increasingly stringent.

Several U.S. state, county and city governments have ongoing retrofit programs for on- and off-road diesel engines, and California's Air Resources Board (CARB) has been a leader in driving increasingly tough emissions standards for heavy duty diesel vehicles.

Historically, most retrofitting in California has been done voluntarily with support from grant programs like those outlined above. However, in 2010, California passed the CARB Truck and Bus Regulation - mandating all 1996 through 2006 diesel trucks in Class 7 (gross vehicle weight of 26,001-33,000 pounds) and Class 8 (gross vehicle weight greater than 33,000 pounds) be retrofitted with diesel particulate filters, if not so equipped, to meet state emission standards between 2012 and 2016, with 90 percent required by 2014.
