Air Pollution Control Devices

U.S. EPA, U.S. Justice Dept. & SCPSA March 16, 2004 settlement requires that SCPSA install and upgrade new flue gas desulfurization devices (scrubbers) for controlling SO2 & selective catalytic reduction devices for controlling NOx on Units 1, 2, 3 & 4. These controls need to be online by 2012.
(status as of June 2004, updated August 2009)
SO2: wet mixture of limestone flue gas desulfurization devices (scrubbers) on all Units.
NOx: Selective catalytic reduction (SCR) on all 4 units. low-NOx burners on Unit 1. Overfire air on Units 1 and 2.
Sources: Title V air permit, govt. agencies, industry, and/or media reports
Units -Year of operation (power)
Unit 1 - 1975 (295 Mw)
Unit 2 - 1977 (295 Mw)
Unit 3 - 1980 (295 Mw)
Unit 4 - 1981 (270 Mw)
