Book Description
Diesel engines play a vital role in key industry sectors such as goods movement, public transportation, construction, and agriculture. A unique combination of efficiency, power, reliability, and durability make diesel the technology of choice for these sectors. However, the durability of the technology does not lend itself to rapid fleet turnover and investment in new equipment that meets more stringent environmental standards. Because of this, the full air quality benefits of the very stringent new engine emission standards in the US2007 Diesel Rule ("Heavy-Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur Control Requirements.") and the Nonroad Diesel Rule ("Clean Air Nonroad Diesel Rule.") will likely take decades to achieve. Further, the regulatory authority of EPA and states to address the existing fleet of over 11 million diesel engines is rather limited. In response, EPA began the Voluntary Diesel Retrofit Program in 2000 to discuss broad initiatives to modernize and upgrade (i.e., retrofit) current engines with modern emission control equipment or to accelerate the replacement of these engines with newer ones. Given the diversity of applications and engines, as well as significant technical and funding issues, the Clean Diesel Retrofit Work Group was formed in 2004 under the auspices of the EPA Clean Air Act Advisory Committee (CAAAC) to advise EPA on how best to expand the initiative.This report is the culmination of the work of the Clean Diesel and Retrofit Work Group since April 2004. It provides consensus-based recommendations as well as other recommendations. Some recommendations are sector-specific; others apply more broadly. It is our hope that this report will substantially further our Nation's efforts to achieve healthy air for its citizens.

Book Description
Air pollution from diesel emissions is a public health concern that reaches every part of the country. There are two main pollutants of concern in diesel exhaust that affect human health: nitrogen oxide (NOx) and particulate matter (PM). NOx is one of the main ingredients in the formation of ground-level ozone, which can trigger respiratory problems. Ozone can aggravate asthma and other respiratory diseases, leading to more visits to the emergency room and increased hospitalizations. Ozone can inflame and damage the lining of the lungs. This may lead to permanent changes in lung tissue and to irreversible reductions in lung function if the inflammation occurs repeatedly over a long time period. PM has been associated with an increased risk of premature mortality, hospital admissions for heart and lung disease, and increased respiratory symptoms. Long-term exposure to diesel exhaust is likely to pose a lung cancer hazard. In addition, PM, NOx, and ozone adversely affect the environment in various ways including visibility impairment, crop damage, and acid rain. The construction sector is a significant contributor to these emissions, creating 32 percent of all mobile source NOx emissions and 37 percent of PM emissions. While stringent new emissions standards are scheduled to significantly reduce emissions from new nonroad equipment starting in 2008, much of the equipment in the current nonroad diesel fleet will continue to operate for many years to come. Therefore, reducing emissions from the existing legacy construction equipment fleet is an important component of EPA's emissions control strategy. The construction sector is highly diverse and is made up predominately of smaller companies. Approximately 92 percent of construction companies have 20 or fewer employees. They tend to be low-margin businesses, with much of their business value accumulated in their capital equipment. Consequently, construction companies resist modifications that they believe will restrict their equipment's operability or increase maintenance. Small companies may not have the ability to spend significant resources to reduce emissions from their equipment. The purpose of this research project was to study and identify low cost ways to reduce emissions from nonroad construction equipment. The report documents the costs and benefits of a number of these strategies - actions that may be taken by small companies (and medium or larger ones as well) in the construction sector to reduce their emissions.

Book Description
Reducing emissions from diesel engines is one of the most important public health challenges facing the country. Despite EPA's stringent diesel engine and fuel standards taking effect over the next decade, the 20 million engines already in use will continue to emit large amounts of nitrogen oxides (NOX) and particulate matter (PM)-both of which will contribute to serious public health problems for years to come. Fortunately, a variety of cost-effective technologies can dramatically reduce harmful emissions, save fuel, and help our nation meet its clean air and sustainability goals. To meet these challenges, the U.S. Environmental Protection Agency (EPA) established the National Clean Diesel Campaign (NCDC). NCDC consists of both regulatory programs to address new engines and innovative nonregulatory programs to address the millions of diesel engines already in use. EPA standards apply to new diesel engines, and because these engines can last a long time, solutions are needed to reduce harmful emissions from the existing fleet. These innovative approaches promote a variety of emission reduction strategies such as retrofitting, repairing, replacing, and repowering engines; reducing idling; and switching to cleaner fuels. Through a dynamic network of Regional Collaboratives, whose development EPA initiated, environmental groups, industry, and government were inspired and motivated-despite their sometimes conflicting perspectives-to unite behind a common goal. NCDC mobilized diverse and unusual partners with historic differences to work together, creating broad support based on the urgency of the public health problem and bringing new technologies into use years earlier than would otherwise have occurred.

Book Description
"This report provides information on the environmental performance of some of America's leading manufacturing and nonmanufacturing sectors. Together, the 12 sectors profiled represent more than 856,000 entities, employ more than 12.6 million people, and contribute more than $3.5 trillion annually to the U.S. economy. This report is an important tool for measuring the performance of these sectors and for determining how we can build on that progress going forward"--Page 2 of cover

Book Description
Medium- and heavy-duty trucks, motor coaches, and transit buses - collectively, "medium- and heavy-duty vehicles", or MHDVs - are used in every sector of the economy. The fuel consumption and greenhouse gas emissions of MHDVs have become a focus of legislative and regulatory action in the past few years. Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two is a follow-on to the National Research Council's 2010 report, Technologies and Approaches to Reducing the Fuel Consumption of Medium-and Heavy-Duty Vehicles. That report provided a series of findings and recommendations on the development of regulations for reducing fuel consumption of MHDVs. This report comprises the first periodic, five-year follow-on to the 2010 report. Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two reviews NHTSA fuel consumption regulations and considers the technological, market and regulatory factors that may be of relevance to a revised and updated regulatory regime taking effect for model years 2019-2022. The report analyzes and provides options for improvements to the certification and compliance procedures for medium- and heavy-duty vehicles; reviews an updated analysis of the makeup and characterization of the medium- and heavy-duty truck fleet; examines the barriers to and the potential applications of natural gas in class 2b through class 8 vehicles; and addresses uncertainties and performs sensitivity analyses for the fuel consumption and cost/benefit estimates.
