Mobile Sources

Mobile engines burn fuel and generate air pollution that impacts the air we breathe.  The U.S. government is responsible for regulating mobile sources .  The DEQ Air Quality Division encourages public awareness and promotes emission reductions through clean air choices.

Pollutants 
Mobile source engines produce air pollutants through combustion or evaporation.  Key pollutants produced include:   Carbon Monoxide  , Hydrocarbons  , Nitrogen Oxides , Particulate Matter , Air toxics  including Diesel exhaust , and Greenhouse gases . 

  TRAFFIC 

Voluntary Programs 

Smartways 
A collaboration between U.S. EPA and the freight industry to increase energy efficiency, reduce greenhouse gases and air pollution

Clean Cities 
A locally-based government and industry partnership, coordinated by the U.S. Department of Energy ( DOE ) to expand the use of alternatives to gasoline and diesel fuel

Action Programs
Includes programs that seek to reduce specific pollutants by a variety of individual actions.  These include self-subscribe notification programs.

EcoDriving Tip Sheet 

Idle Reduction 

No-Idle-sign  


One of the easiest ways to control mobile source emissions is to adopt Idle Reduction policies.  The  Idle Reduction Fact Sheet for Schools  includes information and a draft policy that Michigan school districts are encouraged to implement. Businesses and communities are encouraged to promote savings and cleaner air by advocating for idle reduction policies.
 

Clean Diesel Grants  improve Michigan school Bus emissions.

Clean School Bus USA 
A program from U.S. EPA to reduce children's exposure to diesel exhaust and the amount of air pollution created by diesel school buses.  Since 2004, several Michigan schools have used grants from the Clean School Bus USA program to reduce diesel emissions from their fleets.  More information  is available on these efforts.

Michigan Clean Diesel Initiative  

Detroit Air Toxics Initiative

The Detroit Air Toxics Initiative (DATI) is an initiative to characterize air toxics exposure and health risks in the Detroit metropolitan area.   Funding for DATI was provided by a U.S. Environmental Protection Agency (USEPA) Fiscal Year 2003 Community Assistance and Risk Reduction grant.  A Stakeholder Group consisting of representatives from environmental groups, community groups, government, industry, and universities assisted the AQD throughout this process.  With input from the stakeholder group, a risk reduction project was chosen that would reduce exposure to diesel exhaust in the Detroit area.  To this end, the MDEQ is working with CSX Corporation on a project to reduce diesel emissions from railroad switchyards in the Detroit area.
 

Vehicles and Equipment 

On-road vehicles and Engines (e.g. cars and trucks)
     Heavy Trucks, Buses , and Engines and their emissions  

Non-road  (e.g., marine sources, construction equipment, farm, lawn and garden equipment) 

Fuels 

 

  Photo-of-fueling 

Gasoline  - An overview of EPA programs concerning gasoline fuels.  Another source of information on potential public health concerns from exposure to gasoline  is the Agency for Toxic Substances and Disease Registry.

Diesel   - EPA program information about diesel is available.   Information on concerns with emissions  is also available. 

Alternatives   - including biodiesel, electricity, ethanol, hydrogen, natural gas, and propane.  This site also includes information on fueling stations and alternative fuel vehicles. 


Transportation Planning 

Conformity 
Under the 1990 Clean Air Act Amendments, the U.S. Department of Transportation cannot fund, authorize, or approve Federal actions to support programs or projects which are not first found to conform to the Clean Air Act requirements. The FHWA and the FTA jointly make conformity determinations. 

Congestion Mitigation and Air Quality 
This program, jointly administered by the FHWA and the Federal Transit Administration, provides funds to state and local agencies and organizations to invest in projects that reduce criteria air pollutants from transportation-related sources.  The AQD is part of a collaborative effort along with MDOT and the U.S. EPA and FHWA. 

State and Local Resources 
Useful information, tools and links to resources that identify emission reduction strategies, national policies, regulations, incentive-based programs, funding sources, calculators and other assistance. 

It all adds up to cleaner air!
