Discussion Topics

Hg control assumptions Aggregation/parsing operations Generations allowed Year groupings Retirement vs. off-line costs Time span (2030 end vs. 2015)

Prioritized Hg Control Suggested Changes

Update ACI cost and performance for ESPc (no SC, limited performance)

Offer more menu choices for ACI Update SCR-FGD co-control Update base case co-control

Separate lignite from subbit. Use latest ICR evaluations

Drop SNCR effects on Hg
