Air Permit Number: 95090047 Permitted Source ID/Name: Waukegan 883 Permitted Maximum Process Rate: 3262 mmBtu/hr Max. Normal Operation Process Rate: 3262 mmBtu/hr Target Process Test Rate 3200 mmBtu/hr

Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Unit 8 is a tangentially fired steam generator rated for 2,300,000 pounds of steam per hour. The boiler consists of coal pulverizers, an air supply system, two furnaces seperately set and individually fired, and a convective heat transfer system (superheater amd reheater, economizers and air heaters). Unit 8 utilizes natural gas ignition during startup. Heat produced in the boiler converts water to high-pressure steam in the boiler. Steam is forced through the turbine, causing the turbine blades and shaft to rotate. The turbine shaft turns the attached generator shaft, which produces electricity. Air emissions from Unit 8 result from combustion of fuel within the boiler. Combustion emissions include, but are not limited to, NOx, CO, particulates including PM/PM10/PM2.5, VOM, SO2, sulfuric acid (H2SO4) mist, lead, and various HAPs, including mercury (Hg) and hydrochloric acid (HCl). The emissions generated are controlled (for specific pollutants) through various methods before entering the air via the Unit 8 Stack (ST2). The various methods of control include low NOx burner technology, activated carbon injection (ACI), and electrostatic precipitation. Unit 8 burns low sulfur subbituminous PRB coal.
