Control Strategies and Regulations
Although Wisconsin has yet to develop rules for stationary sources that directly address particle pollution, there are a number of control programs designed to meet other Clean Air Act requirements that provide reductions in the pollutants that form fine particles. Those programs include:
- Wisconsin's acid rain program, which limits emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from power plants;
- the EPA’s website on the Clean Air Interstate Rule [exit DNR], which further limits SO2 and NOx from power plants; and
- Reasonably Available Control Technolgy (RACT) for volatile organize compounds and NOx in southeastern Wisconsin, designed to address high ozone concentrations in the area.
Mobile Sources
There are several state and federal pollution-control programs aimed at mobile sources, including both highway vehicles, such as cars, and off-road equipment, such as all-terrain vehicles (ATVs). The federal government also regulates the fuels these vehicles and other equipment use, with a goal of having cleaner-burning fuels that do not contribute as much air pollution. Regulations include motor vehicle emission standards, vehicle inspection and maintenance, the required use of reformulated gasoline, ultra-low sulfur diesel fuel, low sulfur gasoline, and gasoline vapor-recovery programs.
For more information on mobile sources go to the DNR’s Mobile Source and Fuels webpage.
Voluntary Reduction Programs
Governments, businesses and partner organizations have developed local and regional voluntary programs to reduce air pollution. Find out more on our voluntary programs page.
