Role of Technical Oversight Committee (TOC)
The Technical Oversight Committees responsible for SAMI's Integrated Assessment .  Its 35 members ensure that SAMI's assessment is based on sound scientific information.  Four subcommittees assist the Technical Oversight Committee in managing the assessment of air emissions, atmospheric transport, environmental effects, and socioeconomic consequences.  The Technical Committee works closely with the Policy Committee to develop and analyze responses to changes in emissions due to the 1990 Clean Air Act Amendments, recent revisions to the National Ambient Air Quality Standards, and alternative emissions management strategies that SAMI is considering.

Current TOC Projects
Emissions Inventory: By the end of December, Pechan will have finalized emissions inventories for Bold with Constraints, Bold, and Beyond Bold strategies and supplied seasonal files to the atmospheric modeling contractors for 2010 and 2040 Bold with Constraints strategy. In January Beyond Bold files will go to atmospheric modeling contractors and work will begin on direct costs.  The Subcommittee is beginning work on the direct cost of controls contained in the strategies.

Atmospheric Modeling: Georgia Tech and TVA have completed modeling for 8 of the 9 SAMI episodes for the base year and for the On the Way strategy for 2010 and 2040. Draft results have been delivered for the last episode. Model performance is quite good for sulfate and organics aerosols; uncertainties are greater for nitrate and ammonium. Results for 2010 and 2040 for the Bold with Constraints and Beyond Bold strategies will be delivered between January and April 2001.
