Region 3 Vehicle Retrofit Projects

On February 23, 2005, EPA announced the 2004 voluntary diesel retrofit program demonstration grants to benefit sensitive populations by awarding $1.6 million to 18 grantees for projects designed to demonstrate effective reduction strategies for diesel fleets. The grantees are State and local governmental organizations, including air agencies and port authorities. These grants are part of EPA's new Clean Diesel Campaign. In Region 3, two grants were awarded:

  • Fairfax, Virginia - $75,000 was awarded to retrofit the County's solid waste collection vehicles (18 rear packers and 3 front loaders) and solid waste tractors (49 Class 8 semi-tractors) with diesel oxidation catalyst. In addition, 34 retrofits on other heavy duty diesel trucks of various types will be completed. The county is transitioning to the use of ultra-low sulfur diesel fuel early.

  • Baltimore, Maryland - $75,000 was awarded in partnership with the Baltimore Fire Department to retrofit 37 Fire Trucks and 26 ambulances with diesel oxidation catalyst (Docks) and crankcase filters.

For more information on the grantees and the retrofit projects, visit EPA's "Voluntary Diesel Retrofit Program Grants and Funding" web page.


As a result of a settlement agreement between the United States Environmental Protection Agency and several eastern States, the Virginia Electric Power Company (VEPCO),(now known as Dominion Resources, Incorporated), has agreed to fund numerous diesel retrofit projects in Region 3. These projects meet criteria in the settlement agreement to involve fleets in diverse areas and areas with poor air quality. In addition, these projects advocate the use of engine retrofit technology, replacement with cleaner engines, the use of cleaner fuels and strategies that will reduce engine idling.

  • Temple University: Temple University in Philadelphia, PA proposes to install 10 diesel oxidation catalysts on vehicles in its 20-vehicle fleet of vans, buses and trash trucks. Temple has five regional campuses, three of which are in urban neighborhoods. These urban facilities are embedded in poor neighborhoods that are more likely to show cases of untreated and undiagnosed asthma and other respiratory illnesses. There is a constant, daily sharing of service vehicles and heavy bus traffic moving students and staff, trash and supplies from one urban campus to another, resulting in a much larger emission profile than one would expect. The fleet includes 12 and 16 foot International vans, Cummins 5.9L equipped passenger buses, and International (DT466 7.6L) trash trucks. Model years range from 1985 to 1998. The vehicles targeted for retrofit will not be retired before 2007.

  • Coca-Cola Enterprises, Inc.: Coca-Cola Enterprises (CCE) proposes to reduce emissions from 32 medium heavy-duty delivery trucks that operate in the Harrisburg metropolitan area. The retrofits would include use of fuel borne catalyst (FBC) treated fuel and FBC/diesel oxidation catalysts. CCE has worked with Clean Diesel Technologies, Inc. on a multiple step approach to developing emission reduction strategies for its entire 20,000 vehicle national fleet and is a charter member of EPA's Smartway Transport Program. The FBC system will be used with ultra-low sulfur diesel when available in 2006 for additional reductions. CCE is asking for grant funds for three years of FBC fuel and the DOCs. CCE will install DOCs on 26 vehicles. CCE will keep all retrofitted vehicles at least 4 years.

  • Waste Management: Waste Management is the largest refuse hauler in North America and Pennsylvania. The company's trucks use medium heavy-duty diesel Mack engines that operate in urban areas with frequent stop-and-go traffic. Consequently, there are many accelerations and decelerations performed by a compactor truck, which contributes to particulate matter production. Waste Management has supported retrofit programs for their fleets in other states to alleviate the emissions problem. Total project cost is $358,200. The mitigation grant would cover $336,600 of that amount. The amount would cover purchase and installation of diesel oxidation catalysts, two years supply of a fuel borne catalyst, and a dosing system for installation into the fuel pumps. Waste Management owns and maintains its own fleet of 177 vehicles in the Gilbertsville, PA area. Their vehicles are centrally fueled at a Waste Management owned location. Ninety-four refuse compactor trucks are to be retrofitted with diesel oxidation catalysts. All 177 vehicles will operate on diesel fuel treated with a fuel borne catalyst.

  • The City of Philadelphia's Division of Water and Division of Waste Management proposes to install diesel oxidation catalysts on a mixed fleet of waste handling equipment. This project is envisioned as the first step in an ongoing commitment to achieve further emission reductions from the city's fleet of approximately 3,000 diesel vehicles. The project will begin the process of training city staff to work with pollution control equipment as well as provide a crucial example to other diesel fleets (public and private) for retrofit. The city's Department of Health, Air Management Services, is the convenor of a stakeholder's group, Philadelphia Diesel Difference, to encourage cleaner diesel vehicles in the metropolitan area.The vehicles proposed for retrofit are 1996 – 2002 MY vehicles. EPA-verified diesel oxidation catalysts supplied by Lubrizol/Engine Control Systems (ECS) will be installed on all retrofitted vehicles.

EPA awarded over $500,000 for diesel retrofit projects in several states in 2003. There are a total of six awardees, one located in Region 3.

  • The Maryland Department of the Environment (MDE) was awarded $100,000 to subsidize a one-year supply of ultra-low sulfur diesel (ULSD) fuel to the Maryland Mass Transit Administration's (MTA) Eastern Maintenance Facility, which services 165 diesel transit buses in the Baltimore Metropolitan region. The MDE is providing $39,614 in matching funds. The MTA is the primary transit agency in this area and operates an entire fleet of 829 diesel-powered buses that accumulate more than 22.5 million vehicle miles traveled per year. The MTA is very interested in cleaner fuels and retrofit technologies and will begin this process by converting the 165 buses at this one facility to ULSD fuel.
