Revision to Addendum to Mobile Source Enforcement Memorandum 1A (PDF)
6/1/1998
The purpose of this document is to revise the U.S. Environmental Protection Agency's (EPA's) Addendum to Mobile Source Enforcement Memorandum 1A policy for motor vehicles and motor vehicle engines originally designed to operate on gasoline or diesel fuel and subsequently modified to operate exclusively or in conjunction with compressed natural gas (CNG) or liquefied petroleum gas (LPG or propane).
Using CNG Trucks in National Parks (PDF)
5/1/1998
The U.S. Department of the Interior (DOI) has successfully introduced cleaner-burning alternative fuel (in particular, compressed natural gas, or CNG) transit vehicles, such as refuse haulers electric trams, to relieve traffic congestion and help to protect the National Park System's (NPS) natural resources and historic sites. As part of this effort, NPS and DOI are working with DOE to implement alternative fuels in heavy trucks to attain goals of environmental sustainability and efficient operation. This report outlines the steps required to put CNG trucks in operation in the NPS fleet.
The Pierce Transit Story Case Study (PDF)
1/1/1998
In 1986, Pierce Transit made a commitment to the future of the transportation industry and to the environment by deciding to put buses powered by compressed natural gas (CNG) into everyday service. This case study outlines the company's success and how it was achieved.
The Governors' Ethanol Coalition Marketing Communications Plan (PDF)
12/15/1997
This marketing communications plan is designed to move drivers through the product buying process for gasoline so they seek out and are product loyal to ethanol as a component of their gasoline. Secondly, it is to educate constituents on the advantages of ethanol for the general economic and environmental welfare of the country, thereby enhancing favorable legislative and administrative policy toward ethanol. Some of the strategy used in this market planning document has been adapted from the experience of ethanol advoctes in the State of Minnesota.
The Governors' Ethanol Coalition Research Summary Report. Drivers Awareness, Attitudes & Usage Of Ethanol-Blended Fuel (PDF)
12/15/1997
This summary reports on research done in the Midwest to determine the awareness, usage, and attitudes of drivers toward gasoline blended with ethanol. The goal was to determine why consumers make the choices they do with regard to ethanol at the pump. The most effective key message to encourage driver use of ethanol is its ability to improve air quality, also that ethanol is safe for all engines. Most drivers do not know ethanol's principal features of improving air quality or increasing the octane level of gasoline.
Running Refuse Haulers on Compressed Natural Gas (Case Study) (PDF)
11/1/1997
Since 1992, six new refuse haulers have logged more than 60,000 miles--cleaner, quieter miles, with miles with good horsepower and speed as compared to their diesel counterparts. The U.S. Department of Energy sponsors this project. The Alternative Fuels Data Center at DOE's National Renewable Energy Laboratory has been gathering data on these trucks since they went into service.
Diethyl Ether (DEE as a Renewable Diesel Fuel) (PDF)
10/13/1997
Producing and using renewable fuels for transportation is one approach for a sustainable energy future for the United States, as wel l as the rest of the world. Renewable fuels may also substantially reduce contributions to global climate change. In the transportation sector, ethanol produced from biomass shows promise as a future fuel for spark-ignited engines because of its high octane quality. Ethanol, however, is not a high-quality compression-ignition fuel. Ethanol can be easily converted through a dehydration process to produce diethyl ether (DEE), which is an excellent compression-ignition fuel with higher energy density than ethanol.. DEE has long been known as a cold-start aid for engines, but little is known about using DEE as a significant component in a blend or as a complete replacement for diesel fuel. Dimethyl ether, the methanol analog to DEE, was recently reported to be a low-emission, high-quality diesel fuel replacement, but similar engine testing and process information on DEE is limited. To identify the potential of Dee as a transportation fuel, we conducted a comprehensive literature review of its utilization in engines and also conducted limited laboratory experiments. This paper presents the findings on fundamental engine and emissions performance of DEE, along with an estimated cost of producing DEE from biomass ethanol.

Addendum to Mobile Source Enforcement Memorandum 1A (PDF)
9/4/1997
The purpose of this document is to clarify and revise the U.S. Environmental Protection Agency's (EPA's) "tampering" enforcement policy for motor vehicles and motor vehicle engines originally designed to operate on gasoline or diesel fuel and subsequently modified to operate exclusively or in conjunction with compressed natural gas (CNG) or liquefied petroleum gas (LPG or propane).
The Ethanol Heavy-Duty Truck Fleet Demonstration Project (PDF)
5/1/1997
This report presents the results of an ethanol heavy-duty truck demonstration project. The four trucks were equipped with specially modified Detroit Diesel Corporation engines and ran on E95 (95% ethanol and 5% light hydrocarbon denaturant). They were owned and operated by Archer Daniels Midland Trucking, Incorporated, and were used almost every day for deliveries to points in Illinois, Indiana, Iowa, and Missouri. As a result of this project, a considerable amount of data was recorded, for the first time, on the performance, durability, economics, and emissions of heavy-duty trucks running on ethanol.
A Guide to the Congestion Mitigation and Air Quality Improvement Program (PDF)
4/1/1996
The Congestion Mitigation and Air Quality Improvement (CMAQ) program has been a hallmark of innovation and flexibility under the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). By targeting transportation funding to air quality improvement, it is also unique. The CMAQ program has transferred a far greater percentage of funds to transit improvements than any other "flexible funding" program in ISTEA. In addition, the CMAQ program has created opportunities to build new partnerships in the public and private sectors.
CMAQ Congestion Mitigation and Air Quality Improvement Program - Innovations in Transportation & Air Quality: Twelve Exemplary Projects (PDF)
4/1/1996
The Congestion Mitigation and Air Quality Improvement (CMAQ) program has been a hallmark of innovation and flexibility under the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). By targeting transportation funding to air quality improvement, it is also unique. The CMAQ program has transferred a far greater percentage of funds to transit improvements than any other "flexible funding" program in ISTEA. In addition, the CMAQ program has created opportunities to build new partnerships in the public and private sectors. This brochure highlights several exemplary projects that received CMAQ funds. These projects provide a range of benefits in addition to improved air quality and mobility.
