Tracking No. 2019-021 ST McHale&Associates performed EPA Method 7E NOx emissions testing of the ES-9 and ES-9a over- cladding units. The NOx emissions test results demonstrate compliance with the applicable permit limits as discussed below. Emissions Source ES-9 consists of over-cladding units: Cell 4 and four Cell 5 units venting to a hydrated lime injection dry scrubber fabric filter system IDS which vent to a selective catalytic reduction system 1 SCR. Emissions Source ES-9a consists of over-cladding units: Cells 6, 7, and remaining Cell 5 units venting to a hydrated lime injection fabric filter system 2DS which vent to an ammonia injected selective catalytic reduction system 2SCR. The NOx sampling was performed upstream of the baghouse and lime injection. 15A NCAC 2Q .0317 Avoidance Conditions for 15A NCAC 2D .0530 Prevention of Significant Deterioration applies. Permit Condition 2.2.A.La. states"Total emissions of nitrogen oxides from equipment in Cells 1,2, 3,and 4 and two boilers shall be less than 250 tons per consecutive 12-month period." Permit Condition 2.2.A.Lc requires"Uncontrolled NOx emissions from individual small and large torch Over-cladding Units(Cells 4;ID No.ES-9) shall be tested to determine emission rates in pounds of NOx per unit-hour to be used in demonstrating compliance with the PSD avoidance condition." Permit condition 2.2.B.La states"The nitrogen oxides emissions increase due to equipment operation shall be less than 250 tons per consecutive 12-month period." Permit condition 2.2.B.Le states"NOx uncontrolled emissions from individual new technology torch Over-cladding Units(Cells 5,6,and 7,ES-9a)shall be tested to determine emission rates in pounds of NOx per unit-hour to be used in demonstrating compliance with the PSD avoidance condition." The NO,,emissions results are shown in the table below. Pollutant Source Test Result' Emissions Limit Regulation Compliance ES-9 12.19 lb/hr 250 tpy NO. 53.4 2Q .0317 Yes ES-9a 49.72 lb/hr 250 tpy (214.97 tpy) 'tpy calculated based on 8760 hrs/yr The test results are acceptable for demonstrating compliance with the 2Q .0317 avoidance limitation for ES-9 and ES-9a.
