Diesel moves approximately 90 percent of America’s freight. Diesel engines power nearly all delivery trucks, freight trucks, locomotives and commercial marine vessels. The Air Pollution Control Program wants those diesel engines to keep Missouri’s skies cleaner while they are moving our nation’s goods on down the road.
Under the State Allocated Diesel Emission Reduction Act Funding for 2012, the Air Pollution Control Program received a grant from the U.S. Environmental Protection Agency, or EPA, to fund a clean diesel program in Missouri.
The program used the grant to award subgrants to St. Louis Regional Clean Cities and to the Ozark Center for Sustainable Solutions at Drury University.
St. Louis Regional Clean Cities will receive a subgrant for $108,250. The St. Louis area project will include repowering the 1984 propulsion engines on a 600-horsepower tugboat with new cleaner and more efficient engines that meet more stringent federal emission standards. In addition, a 2000 model year class 8 long-haul tractor-trailer that is used to fulfill pick-up and delivery contracts in all of Missouri’s major metropolitan areas will be replaced with a new truck with an engine meeting the latest EPA emission standards for heavy-duty diesel vehicles.
The Ozark Center for Sustainable Solutions at Drury University will be receiving a subgrant for $82,000. The southwest Missouri area project will include the early replacement of two 1997-model year school buses owned by Logan-Rogersville and Hollister School District, respectively. The new bus engines will meet the latest EPA emission standards for school buses. In addition, one 1990 dump truck owned by APAC will be replaced with a new truck that will operate exclusively on compressed natural gas as opposed to conventional diesel fuel.
These projects are expected to keep more than 3,200 tons of diesel emissions from entering Missouri’s air through the life of the vehicles and engines that will be replaced or repowered. This is also expected to conserve thousands of gallons of diesel fuel each year for the combination of fleets included in the project.
The Air Pollution Control Program is committed to reducing diesel emissions in Missouri. Diesel emissions contain oxides of nitrogen as well as volatile organic compounds, which in the presence of sunlight, react to form ground-level ozone, the pollutant of most concern statewide in Missouri. Ozone is known to cause and aggravate respiratory diseases such as asthma.
Diesel emissions also contain fine particulate matter, which can penetrate deep into people’s lungs past their natural defenses. This can lead to a variety of different lung and respiratory disease including lung cancer. Reducing diesel emissions, particularly in areas with disproportionately high concentrations of air pollutants is vital to the Air Pollution Control Program’s mission of protecting public health.
