Missouri Clean Diesel Program

traffic imageThe goal of Missouri's Clean Diesel Program is to improve air quality by reducing diesel emissions from on-road and off-road engines operating in the state.

Since 2008, the department has implemented state Diesel Emission Reduction Act (DERA) programs each year to help fund projects for diesel fleet owners and operators in Missouri to reduce their emissions. When opportunities under the state DERA program become available, they will be listed on this webpage.

2014 Missouri Clean Diesel Program (Tugboat Engine Repower Program)

Under the state allocated DERA funding for 2014, the Department of Natural Resources’ Air Pollution Control Program received a grant from the U.S. Environmental Protection Agency to fund a clean diesel program in Missouri.

The 2014 Missouri State Clean Diesel Program targets engine repower projects for tugboats that operate within or along the border of Missouri.  Many tugboats operate 24 hours a day, seven days week, stopping operations only a few times a year for maintenance and repairs.  Tugboats often operate near ports in large, densely populated metropolitan areas that receive disproportionately large amounts of diesel emissions.  For these reasons, repowering tugboat engines to reduce emissions maximizes public health benefits.  Tugboat fleets that repower their vessels often report large fuel efficiency improvements that help to reduce the consumption of diesel fuel, lowering dependence on fossil fuels.

The Selection Process

The Air Pollution Control Program developed a request for applications soliciting tugboat engine repower projects to be implemented through the 2014 Missouri State Clean Diesel Program.  Applications for tugboat engine repower projects were accepted through Aug. 29, 2014.  All tugboat fleet owners and operators with tugboats operating at least 50 percent of the time within or along the border of Missouri were eligible to apply for this funding opportunity.  Selected awardees are eligible to receive up to 50 percent of the cost of the parts and labor necessary to perform the engine repowers.  In order to ensure emissions reductions are achieved through this program, the engines being replaced must be permanently disabled after the new engines are installed. One applicant has been selected to receive funding through this program.  See below for information regarding the selected project.

Selected Project

St. Louis Regional Clean Cities and JB Marine Inc. are partnering to repower the auxiliary and propulsion engines on a tugboat owned by JB Marine that operates exclusively in the St. Louis area.  The project is expected to be completed in 2015.

Improving Air Quality

The Missouri Department of Natural Resources is committed to developing ways to reduce diesel emissions which contribute to ambient particle concentrations and the formation of ground-level ozone. Diesel emissions are known to cause and aggravate lung and respiratory diseases such as asthma. Reducing emissions is an important step toward protecting public health and improving the air quality in Missouri.
