Emissions Management Strategies

Source sectors often discussed are stationary, mobile and area sources. Mobile sources are often divided into on-road and off-road. They include autos, trucks, weed-eaters and ocean liners. Stationary sources are typically utility or industrial boilers. Area sources include such sources as dry cleaners, agricultural emissions, and road dust.  More information is available under Emissions Inventory.

The Integrated Assessment model developed by the technical committee will test a series of strategies that represent emissions levels in 2010 and 2040.  The "On the Books" strategy represents implementation of the emissions controls required by the Clean Air Act when SAMI was formed in 1992.  This strategy will serve as the reference case against which emissions strategies are evaluated.  The second strategy, "On the Way", represents emissions reductions that have been mandated by the Environmental Protection Agency since SAMI began. Represented rules include EPA's call for regional NOx reductions through state implementation plans, the revised national ambient air quality standard for ozone, and Tier II and low sulfur fuel controls for mobile sources controls.   A third strategy termed "Maximum Control" will examine the effect of applying the most advanced technologies for emission controls to all source sectors. The regional haze rule and the revised national ambient air quality standard for fine particles will be considered in a separate strategy if sufficient information on state's plans for implementation becomes available in time to be included in SAMI's assessment. 

A total of nine strategies will be evaluated to help SAMI decide which controls to recommend to its eight member states that will "remedy existing and prevent future adverse effects from human-induced air pollution".

Policy Committee
The SAMI Policy Committee is responsible for developing strategies to be modeled by the Technical Committee and recommending the most promising of these to the Operations Committee for consideration by the Governing Body. The Policy Committee often meets with the Technical Committee to advise them on possible policy implications of technical decisions. It is composed of 35 members. Each SAMI state nominates three persons, one each from industry, government and the public interest sectors. EPA Region III, Region IV and Headquarters are represented. The USFS and National Park Service each are represented and jointly appoint a public interest and an industry representative.

Growth in the SAMI states:
In the eight SAMI states, population, energy demand, and vehicle use are projected to increase significantly between 1990, 2010, and 2040.  Emissions reductions are occurring for major pollutants (sulfur dioxide, nitrogen dioxides, volatile organic compounds) despite these increases in demand.
