Kentucky Clean Diesel Programs

Reducing emissions from diesel engines is one of the most important air quality challenges facing the country. 

  • There are 20 million mobile source diesel engines in operation nationwide.
  • These engines emit some 300,000 tons of particulate matter (PM) and 6.4 million ton of nitrogen oxides (NOx) into the air each year.
  • These pollutants contribute to a range of public health problems, including asthma, lung cancer, and many serious cardiac and respiratory diseases.

Even with more stringent heavy-duty highway and non-road engine standards taking effect over the next decade, millions of diesel engines already in use - known as the "Legacy Fleet" - will continue to emit large amounts of PM, NOx and toxic air pollutants into the air we breathe.

 

What is Clean Diesel Technology?

 

Diesel engines are the work horses of our nation’s fleets, providing more power and fuel efficiency than engines that burn gasoline and natural gas.  “Clean diesel” refers to a number of advancing technologies that aim to reduce harmful emissions of PM, NOx, and toxic air pollutants from diesel exhaust.  Diesel particulate filters, auxiliary power units, and engine repowers are some of the technologies now available to help “clean and green” older vehicles.  It all adds up to cleaner air and healthier communities.

Crittenden County's Cleaner School Buses

Crittenden County Board of Education has been awarded approximately $95,000 to replace four old unretrofitted diesel school buses with four new propane autogas school buses. Crittenden County obtained the first propaned-powered bus for student transportation in the state last year and is thrilled with the cost savings and emissions reductions. The new propane buses produce 98 percent less NOx emissions and 100 percent less particulate matter emissions than the old diesel buses they are replacing. The addition of the four new propane buses will also save the school district an estimated $13,000 in fuel and maintenance in the upcoming school year alone.


Past Funding Awards
 

2012 Funding:  Crittenden County used about $70,000 to retrofit 14 school buses with diesel oxidation catalysts (DOCs) and closed crankcase ventilation (CCV) systems and to fund part of the cost of replacing a 1992 diesel bus with a 2014 propane school bus – the first in the state!  Louisville Metro Government used about $50,000 to retrofit two additional refuse haulers with diesel particulate filters (DPF) and purchase a DPF control panel, continuing their project from past years.
 
2010 – 2011 Funding:  Louisville Metro Government received $425,880 in these two years of clean diesel funding to retrofit 18 refuse haulers with DPFs and CCV systems.
 
2009 Funding:  Two projects were awarded a total of $235,000. The first of these was a truck replacement and idle-reduction project with an independent owner-operator long-haul trucking operation. The second was implemented by Lexington-Fayette Urban County Government, which led to the retrofit of 13 refuse haulers in the fleet.
 
In the spring of 2009, DAQ received $1.73 million in Diesel Emissions Reduction Act (DERA) funding through the 2009 American Recovery and Reinvestment Act, and the division chose to utilize this funding to expand 2008’s Kentucky Clean School Bus Grant Program.  Twenty-two school districts reduced diesel emissions in their districts through the installation of emission control devices in their bus fleets. The funded school districts included Ashland Independent, Corbin Independent, Daviess County, Elizabethtown Independent, Floyd County, Frankfort Independent, Franklin County, Gallatin County, Grayson County, Jefferson County, Lincoln County, Livingston County, Madison County, Marion County, Montgomery County, Owsley County, Pike County, Pulaski County, Somerset Independent, Spencer County, Taylor County and Warren County. In addition to the bus retrofits performed, each school district also implemented an idle-reduction policy in their school bus fleet. The division encouraged this as a component of participation in the Clean School Bus Grant Program, and DAQ staff provided educational materials, templates and support for the adoption and implementation of these policies.
 
2008 Funding:  During the inaugural year of the Kentucky Clean School Bus Grant Program, DAQ awarded $196,000 in DERA funds to six school districts in Kentucky to help reduce emissions in their districts through the installation of DOCs and CCV systems on their school buses. The following counties received funding: Bell, Boone, Fayette, Franklin, Jefferson and Paducah Independent Schools.
