Clean Diesel Initiative in Michigan

Contact:  Donna Davis (517) 335-2784
Agency: Environmental Quality


What is the Michigan Clean Diesel Initiative (MiCDI)? 

The MiCDI is a group of government, industry, and nonprofit organizations working together to address diesel engine pollution in Michigan.  The objectives of the MiCDI are to help the state of Michigan achieve improvements in the federal air quality standards for particulate matter and ozone by:   

  • Working with specific geographic areas and industry sectors of Michigan to identify where environmental improvements can be made through diesel emission reductions, including reasons for the emission reductions and major sources in the affected areas. 
  • Encouraging the development and expansion of innovative technologies that can be used by these industry sectors as well as ways to implement diesel emission reductions at the local level. 
  • Acting as a conduit to help identify funding opportunities and resources that can be used to implement diesel reduction technologies and strategies, and to provide resources for the application process. 

Funding for Clean Diesel Projects

Congress appropriated funds under the auspices of the Energy Policy Act (2005) to help reduce harmful emissions from heavy duty diesel engines. The MDEQ awards grants to assist its eligible partners in building diesel emission reduction programs across the country that improve air quality and protect public health.

Diesel Emission Reduction Act (DERA) - State Clean Diesel Grant

Eligible Partners 

The MDEQ defines eligible partners as cities, townships, and villages; county government agencies; port authorities; public school districts; private schools; other non-profit organizations or institutions that promote transportation or air quality as their focus; metropolitan planning organizations and private business industry.

Types of Projects Eligible for Grant Awards 

Grant projects must include the application of a diesel emissions reduction solution that is an emission control technology that has been verified by either the U.S. EPA or California Air Resources Board (CARB). Examples of U.S. EPA or CARB-verified emission control technologies include:

  • Retrofit Technologies (i.e. oxidation catalysts, aerodynamic hoods and particulate matter filters)
  • Idle Reduction Technologies (i.e. auxillary power units and generator sets).
  • Engine Repowers (i.e. replacement with new or cleaner engine and scrappage of old engine).
  • Vehicle and Equipment Replacements (covering between 25-50% of cost).
  • Aerodynamic technologies (i.e. long haul truck side skirts, hoods, etc).

Eligible Vehicles and Equipment 

  • Medium to heavy duty diesel vehicles, engines and ground installations used for either on-road or non-road applications (i.e. trucks, buses and other diesel equipment used for construction, handling cargo, farming, mining and energy production).
  • Marine engines (i.e. tugboats and pushboats, ferries, excursion vessels , dredging equipment, container ships, tanker ships, bulk carrier ships and cruise ships).
  • On-road or non-road applications that provide heat, air conditioning or electricity service to vehicles and equipment that is stationary or temporarily parked (i.e. generator sets).

Meeting Schedule

The MiCDI meets approximately 3-4 times a year in different parts of the state.  The following is a list of past meetings and an upcoming meeting schedule:
