Permitted Maximum Process Rate: Max. Normal Operation Process Rate: Target Process Test Rate

Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Unit 40 discharges exhaust gases to two separate stacks. Testing was performed for each parameter of each grouping simultaneously on both stacks. Per EPA’s guidance, the test results are presented for each stack individually. The test results for each stack have not been combined or summed in this report. EPA will determine how the unit emissions will be summed following receipt of the test report and ERT submittal.
