St. Louis Diesel Retrofit Program
The Missouri Department of Natural Resources has received a $55,000 grant to reduce diesel emissions through a diesel equipment retrofitting pilot project in St. Louis. The department has partnered with the Grace Hill Clean Air Program in St. Louis to use a portion of the grant to retrofit five trucks, in five different trucking fleets in the St. Louis area.
The trucks will be equipped with SmartWay℠ packages that consist of diesel oxidation catalysts and diesel particulate filters that have been developed to reduce diesel emissions. Idle-free zones will also be established by participating companies. Studies have shown that SmartWay℠ packages pay for themselves in terms of fuel savings, over and above the diesel emissions reductions that they are designed to achieve. Fuel cost savings of up to 40 percent are estimated, and an equivalent reduction in greenhouse gas emissions is expected.
The St. Louis Diesel Retrofit Workshop and Expo presented SmartWay℠ diesel retrofit equipment and idle reduction strategies. Trucking, industrial, commercial and service fleet operators were invited to attend. Improving fuel efficiency, air quality and reducing greenhouse gas emissions go hand in hand.
Air pollution is a known factor influencing the development and expression of asthma. It is Documented that the closer children live to a freeway, the greater their chances of being diagnosed with asthma. The National Institutes of Health reported that increased pollution levels, particularly of respirable particulates and ozone and also of Sulfur Dioxide and Nitrogen Oxide, have been reported to trigger symptoms of asthma and to increase emergency department visits and hospitalizations for asthma. The St. Louis Regional Asthma Consortium strongly supports local efforts to reduce these harmful diesel emissions.
Ozone is also a primary pollutant of concern in Missouri. When pollution from vehicle emissions combines in the presence of heat and sunlight, ground-level ozone, commonly known as smog, is created. Ground-level ozone is an irritant that damages lung tissue, aggravates heart and respiratory disease and can even cause problems for healthy individuals who spend a lot of time outdoors. Air quality in St. Louis, measured against the National Ambient Air Quality Standards, shows that we are not yet attaining this health-based standard. As a nonattainment area, the St. Louis community must continue to take actions to prevent the formation of ground-level ozone. Control devices, such as diesel retrofitting and vehicle emissions testing, are an important part of protecting air quality. Controlling harmful emissions and making air conscious decisions are necessary in order to protect public health and prevent the formation of ground-level ozone.Presentations

Particulate matter filters can achieve 60 to 90 percent reductions in diesel particulate matter, hydrocarbon, and carbon monoxide emissions. They can only now begin to be installed since the introduction of ultra-low sulfur diesel fuel in October 2006.
Diesel oxidation catalysts - Diesel oxidation catalyst, also known as DOC's, reduce emissions of diesel particulate matter by at least 20 percent, hydrocarbons by 50 percent and carbon dioxide by 40 percent.
Newer technology such as the Peterbilt-Eaton Hydraulic Launch Assist® will be made available, if possible, for use on local trucks and buses that make frequent stops and starts, such as refuse trucks and city buses:
