MEMORANDUM
To: Bruce Ingle,Mooresville Regional Office Supervisor
From: Brent W.Hall, Stationary Source Compliance Branch4*
Subject: Prysmian Cables and Systems USA, LLC
Claremont, Catawba County,North Carolina
Facility ID 1800419,Permit No. 07334T27
Nitrogen Oxides(NOx)Testing of Over-cladding Lines ES-9 and ES-9a
Performed February 6,2019 by McHale&Associates,Inc.
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. If there are any questions regarding this review,please contact me at 919-707-8427 or
