Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The South Oak Creek Power Plant is an electric power generating station consisting of 4 boilers which use subbituminous coal with natural gas for coal flame stabilization at low loads and boiler startup. Boilers #5 and #6 are wall-fired boilers, while Boilers #7 and #8 are tangentially fired. Particulate matter emissions are controlled by electrostatic precipitators, which were installed in 1972 (Boilers #5 and #6) and 1991 and 1992 (Boiler #7 and #8, respectively).
