New Report by EPA Details Cost-Effectiveness of Diesel Retrofits

The EPA has released "Diesel Retrofit Technology: An Analysis of the Cost Effectiveness of Reducing Particulate Matter and Nitrogen Oxides Emissions from Heavy-Duty Nonroad Diesel Engines Through Retrofits." Available online as a 17-page PDF, the report discusses retrofit options, how they can be a cost-effective strategy for off-road diesel vehicles in reducing emissions, and estimates for various retrofit scenarios.

From the report:
Retrofit projects can begin producing emission reductions immediately and can help State and local governments reduce emissions of PM2.5, nitrogen oxides (NOx), and volatile organic compounds (VOC) in the near term. Retrofits include a wide range of emission reduction strategies available for diesel vehicles and equipment, including:

• Retrofitting engines with verified technologies
• Using cleaner fuels
• Replacing older equipment
• Repowering (replacing old engines with new, cleaner engines
• Reducing idling
• Properly maintaining equipment
• Gaining operational efficiencies

Retrofit technologies are advancing at a rapid pace. The use of established technologies, such as diesel oxidation catalysts (DOCs) and diesel particulate filters (DPFs), continues to grow exponentially, while new, emerging technologies such as Lean NOx (LNC) catalysts, are steadily improving. Retrofit technologies often vary in the type of pollutant reduced. DOCs and DPFs remove PM from the exhaust, but do not reduce NOx. However, DOCs or DPFs can be combined with a NOx reduction strategy – such as a cleaner fuel – to enhance the emission reduction benefits.
