1. Diesel Retrofit Projects: An Introduction National Tribal Forum on Air Quality April 19, 2007 Ken Cronin

2. 1 Overview Why Diesel Retrofits? What funding is available? Diesel Retrofit Boot Camps

3. 2 Why Reduce Emissions from Diesel Engines? Diesel engines contribute to air pollution – PM 2.5 – Ultra-fine solid particles – NO x – Toxic HC – SO x Increased stringency of EPA air quality regulations to reduce above pollutants Benefits to society in reducing emissions from diesel engines –Better protect the public health (e.g. reduce asthma attacks) –Reduce visibility impairment –Protect agriculture –And much more

5. 4 U.S. Diesel Fuel & Vehicle Programs 2000 Heavy-duty 2007-10 Standards: – Diesel sulfur control (15 ppm maximum) – Stringent heavy-duty diesel vehicle standards (90% reduction) 2004 Nonroad Tier 4 Standards: – Diesel sulfur control (2 steps - 500 ppm in 2008, 15 ppm in 2011) – Stringent emission standards, based on on-highway standards (in most cases 90% reduction) Locomotive and Marine Diesel Standards: – Marine diesel sulfur control (15 ppm maximum in 2011) as part of nonroad rule – Same type technologies as on-highway and nonroad expected – Proposed rulemaking in late 2006 or early 2007

7. 6 But What About Existing Offroad Diesel Engines? Public health cannot wait 25 years Approximately 11 million total diesel engines of which approximately 5 million offroad diesel engines are in operation today in the U.S. Diesel Engines are extremely durable – 2030 before existing fleet turns over Retrofit technologies, clean fuels and operational changes can make a difference

8. 7 Funding Diesel retrofit project popular with current administration Approximately $50-$70 Million Available for diesel retrofit projects

9. 8 Examples of Federal Grants for Tribal Retrofit-Related Activities U.S. Dept of Agriculture – Scientific Cooperation Research Program U.S. Dept. of Agriculture – Environmental Quality Incentive Program (EQIP) U.S. Dept. of Agriculture – Pollution Prevention Grant Program U.S. Department of Transportation – Tribal Technical Assistance Program U.S. Environmental Protection Agency – Pollution Prevention Grant Program U.S. Environmental Protection Agency – Tribal Air Pollution Control Program U.S. Environmental Protection Agency – State and Tribal Assistance Grants (STAG) U.S. Environmental Protection Agency – Community Action for a Renewed Environment Source: EPA

10. 9 What is the Diesel Retrofit Boot Camp™ A comprehensive, interactive training approach for those interested or involved in planning, implementing, and evaluating programs to reduce emissions from existing diesel engines, as well as those who are considering using retrofit products The Boot Camp is designed as a two-day program, but can easily be modified to fit the particular needs and time availability of those attending The Boot Camp was developed for the Western Regional Air Partnership (WRAP) by Emissions Advantage, LLC, –Seven Boot Camps were presented in 2006 with a combined attendance of over 300 participants

11. 10 What Retrofit Strategies are Covered in the Diesel Retrofit Boot Camp™ Retrofit – Exhaust emission control technology, crankcase emission control, engine control modules Refuel – ULSD, biodiesel, emulsions, additives, electrification, alternative fuels Repair/Rebuild – maintenance, repair, engine component upgrade, Repower – Install new engine in existing vehicle/equipment Replace – Replace existing vehicle/equipment Reduce – Limit idling, and other operational changes

12. 11 Subjects Covered in the Diesel Retrofit Boot Camp™ The Retrofit Program Development Process Retrofit Program Experience and lessons Learned Identifying and Acquiring Funding Developing Retrofit Partners Fundamentals of Diesel Engine Operation Technology-Based Retrofit Strategies and Applications Fuel-Based Strategies and Applications Operational-Based Strategies and Applications Choosing Emission Reduction Strategies, Acquiring Products, and Implementing Programs Interactive Program Planning Training Session

13. 12 What are the Benefits of Attending the Diesel Retrofit Boot Camp™ Learn how to: Plan, design, and implement a successful retrofit project Select the right retrofit technologies and strategies to meet your program objectives –Understand the basics of each retrofit strategy, when it can be applied, the benefits and the application limitations Identify sources of funding for your retrofit project Use proven techniques in writing a request for grant funding Build partnerships and recruit fleet participants Develop methods to evaluate your retrofit project
