With program management and administrative support from Virginia Clean Cities, Gloucester County Public Schools (GCPS) replaced five 16 – 17 year old diesel school buses with propane school buses meeting 2010 emission standards.   This was the first propane bus program in Virginia and it was part of the larger Clean School Bus USA Middle Peninsula Project.

Total Cost:  $448,836 ($227,481 grant funding)


According to GCPS School Board Chairperson, Anne Burruss, "The positive impact on cost savings, morale of both drivers and students, the benefits realized from a safety standpoint are major plusses in our purchase of the propane buses ... As a School Board member, it was and continues to be, a source of great pride in being first in the Commonwealth of Virginia for these vehicles to be in a school bus fleet." 

MARAMA supported this project with a grant from the the Virginia Department of Environmental Quality under the American Recovery and Reinvestment Act (ARRA), funding 50 percent of the bus purchase cost plus 100 percent of the cost of  diagnostic equipment and parts to assist in servicing the new propane buses.  Gloucester County Public Schools provided the remaining funding.







The Statewide Biodiesel Buy Down created a fund to compensate the Virginia Port Authority’s (VPA) cargo handling operations and fleets operating in the Commonwealth of Virginia for the cost differential between biodiesel and petroleum diesel and associated fuel change costs such as the cost of the initial fuel filter change.  This project promoted the use of biodiesel by providing up to $1.00/gallon differential cost depending on the blend of biodiesel used.  Blends from 2% to 99% biodiesel were eligible under the program.

In response to a Request for Proposals (RFP) issued to state government fleets operating in the Commonwealth of Virginia, MARAMA approved proposals from the Virginia Port Authority (VPA) and James Madison University (JMU) to reimburse the cost differential between B5 biodiesel and petroleum diesel at the Port of Virginia and between B5 and B20 biodiesel and diesel at JMU.

This project encouraged the use of cleaner and domestically produced alternative fuels by subsidizing the incremental cost over the cost of petroleum diesel.  An important lesson of the project was that all parties involved should discuss and agree on fuel use and cost documentation requirements before beginning the fuel switch.


Total Cost:  $11,110 (100% grant funded) 



With a subaward funded by an EPA Region 3 grant to MARAMA, the City of Philadelphia retrofitted 68 fire engines with diesel oxidation catalysts (DOCs).  The retrofitted fire trucks serve 53 fire house throughout Philadelphia.  This demonstration project highlighted the emission reduction capability of DOCs on fire trucks and addressed potential installation and operational barriers.   Philly fire truck

  Since the retrofits were done during routine comprehensive preventive maintenance (PM) and loaner engines are provided for use during PM, the retrofits were completed without compromising public safety, which was of concern because most of Philadelphia’s fire stations have only one pumper truck, and none possess more than two.

  Total cost: $148,447 ($89,000 grant funded)

The U.S. Environmental Protection Agency (EPA)  awarded the Mid-Atlantic Regional Air Management Association, Inc. (MARAMA) $1.3 million for clean diesel projects as part of the Diesel Emission Reduction Program (DERA) and its ongoing campaign to reduce harmful diesel exhaust that can lead to asthma attacks and premature deaths.

Grant funds repowered three marine vessels and retrofited drayage trucks. Award recipients were selected based on potential for maximizing health and environmental benefits by targeting areas that have significant air quality issues. Reduced air pollution from diesel engines in these areas can have a direct and significant impact on public health.


The Maryland Port Administration (MPA) was the first port to install diesel oxidation catalysts (DOCs) on ship-to-shore (STS) and rubber-tired gantry (RTG) cranes, and this project involved the first installation of DOCs on MPA cranes.  MPA's primary goal in installing the DOCs was to decrease the particulate matter (PM), volatile organic compounds (VOCs) and carbon monoxide (CO) emitted by the two cranes involved in the demonstration.  It was critical to MPA that the DOCs have no adverse effect on the cranes, either by damaging the cranes or by impairing the crane operations.    RubberTiredGanrtyCrane POB

   This demonstration project highlighted the emission reduction capability of DOCs on port cargo-handling equipment and addressed potential installation and operational barriers.  Based on the success of this demonstration, MPA applied for and was awarded a Recovery Act grant that included funding for additional cargo-handling equipment retrofits.
