7. TEC Consent Decree (CD) and Consent Final Judgement (CFJ)
TEC is required to repower F.J. Gannon Station, a coal fired electric generation facility, to Bayside Power Station, a natural gas fired electric generation facility
TEC is required to optimize the Electrostatic Precipitators (ESPs) at Big Bend Station
TEC is required to upgrade the removal efficiency and availability of the scrubbers (FGDs) at Big Bend Station
TEC is required to make substantial early and long term reductions in NOX emissions from the units at Big Bend Station by 2010
Upon completion of the above projects, emissions levels from all TEC units will be comparable to emissions levels from new units utilizing the same fuels

8. Nitrogen Oxides (NOX)
By 2010, TEC will have reduced NOX system wide by approximately 85%
Gannon NOX reductions: repower to natural gas
Big Bend NOX reductions: addition of Selective Catalytic Reduction (SCR) system
NOX emissions from Polk Unit 1 IGCC were already low, and were reduced again prior to July 2003

14. Mercury (Hg)
By 2010, TEC will have reduced Mercury system wide by approximately 73%
Gannon Hg reductions: repowering to natural gas
Big Bend Hg reductions: currently achieving co-benefits from existing pollution control technologies - electrostatic precipitators (ESPs) and flue gas desulfurization (FGDs or scrubbers) systems, additional co-benefits expected from addition of SCRs
Hg emissions from Polk Unit 1 IGCC are already low
