LOCATION: Piedmont Natural Gas—Wadesboro Compressor Station,259 Pleasant Grove Church Road,Wadesboro,NC, Anson County. II. DIRECTIONS: From FRO,take US Hwy 401 South through Raeford and Wagram. Just outside Wagram,turn right onto Old Wire Road(NC 144). Follow Old Wire Road across US 151501 and through Laurel Hill to US 74. Turn right onto US 74. Follow US 74 35 miles to Wadesboro,then turn right onto N. Greene St/NC Hwy 109. Drive 4.9 miles,then turn left onto Pleasant Grove Church Road. The Piedmont facility is located approximately 0.3 miles on the left side of the road. III. SAFETY CONSIDERATIONS: The usual FRO safety gear is required, including hard hat, safety shoes,safety glasses,and hearing protection. There may be numerous pieces of equipment operating on site,including forklifts,personnel lifts,trucks,cars, and other vehicles. At the time of this stack test,the compressors were not operating. The facility was operating only the emergency generator engine(EGO1). 7-1� 4, 4 ,;I, 1k ,- %,�,,-,', ,J'��;1-11-- �-4�1_-1.A Zz", 'M �,;�,q-t,,I..q V, N't wr -1-4-2..4 v E!"�1 -7 --g-p. v wnn� �1;74 6415 z�_;,-4 7,�We� ,;p ".

FACILITY DESCRIPTION: The facility is a large natural gas pipeline compressor station. The facility accepts natural gas from the Trans- Continental distribution pipeline at 500-800 psig pressure and compresses this gas to 800-1,000 psig for injection into the Piedmont pipeline to transport it to its destination. The gas pipeline leads eventually to the Duke Sutton electrical power generation plant in Wilmington. The Piedmont facility consists of four(4)natural gas-fired 4,735 HP compressors(8 are permitted at the facility),plus a 770 HP natural gas-fired emergency generator. All the engines are fueled by natural gas pulled directly from the gas transmission pipeline. The facility operates only as needed to supply the gas demand downstream of the compressor station,usually in the colder winter months. V. TEST CHRONOLOGY: 09/22/2021 Piedmont submitted a request for testing of only one of the four compressor engines as representative of all four. 12/21/2021 SSCB issued an approval letter for the waiver to test only one compressor engine. 02/08/2022 SSCB received a letter from the company with testing protocols and stack test notification for the Wadesboro facility. Stack testing was proposed for the four-cycle lean burn stationary reciprocating internal combustion engines(COMPO 1 through COMP04)and the emergency generator engine(EGO1)at this location. The proposed date for the test was during the week of 4 April 2022. 02/14/2022 The facility was granted a revised"Waiver for Emissions Testing of One Natural Gas Engine as Representative of Emissions for Engines COMPO I-COMPO4 and EGO 1" in a letter from Mr. Stephen Hall. This waiver exempts COMPO 1 from the 2022 subject testing. Engines COMP02 through COMP04 are all tested in 2022 since none of these engines have been tested since 2016. After the 2022 testing is completed,at least half of the subject engines are tested once every three years with all engines being tested at least once every 6 years. 03/30/2022 DAQ SSCB reviewed the testing protocol and deemed it acceptable. Testing is for the periodic performance testing required under NSPS Subpart JJJJ. 05/10/2022 Stack testing commenced on emergency generator engine(EGO1). VI. PURPOSE OF STACK TEST: The purpose of this test is to demonstrate continuing compliance with the NSPS Subpart JJJJ emission limits for the emergency generator natural gas-fired reciprocating internal combustion engine. This engine is not an EPA "certified" engine, and thus a stack test is required to demonstrate compliance with the NOx, CO, and VOC emission standards under the NSPS regulation. The testing is required every 8,760 hours of operation or every three years,whichever comes first. This engine is seldom run except for short periods for testing every week.

Piedmont Natural Gas—Wadesboro Compressor Station Stack Test Observation Report Page 3 of 4 The engine being tested is a Waukesha 880 HP natural gas-fired engine, driving a 600 KW electrical generator (ID No. EGO 1). Under NSPS Subpart JJJJ,the emission limits for this engine(40 CFR 60, Subpart JJJJ,Table 1)are as follows: Emission Limit Emission Limit Pollutant glhp-hr ppmvd @ 15%Oa ._._................... NOx 2.0 160 CO 4.0 ; 540 VOC E (Non-Methane Hydrocarbon) 1.0 86 g/hp-hr=grams per horsepower—hour ppmvd=parts per million by volume,dry basis,corrected to 15%02 content Note that the owner or operator can choose to comply with either the emission limit in g/hp-hr OR the emission limit in ppmvd% 15%02. The approved test methods are as follows: Target Proposed Test Run Time Standard Emission Limit Pollutant Method ......... ..... ..._...,..._.-.. _._....___ x Volumetric 1 EPA Method 3 runs,60 minutes each Flow ! 1 &2 Concurrent with(320) Molecular 3A 3 runs,60 minutes each Weight Oxygen Concurrent with(320) Moisture EPA Method 320 --- --- Content NOx EPA Method 320 60 Subpart JJJJ (or160 ppmvd@15%02 3 runs,60 minutes each -- — - ---� CO 4.0 /HP-hr EPA Method 320 60 Subpart JJJJ g ° (or 540ppmvd @15/0 02 I VOC EPA Method 320 11 60 Subpart JJJJ (or 86 ppm 5%02 Testing is to be conducted at full load± 10%. Proposed testing rate was 804 HP. VII. STACK TEST OBSERVATIONS: On Tuesday May 10,2022,I,Evangelyn Lowery-Jacobs of the Fayetteville Regional Office,arrived at the Piedmont Natural Gas—Wadesboro Compressor Station site to observe stack testing of the emergency generator engine(EGO 1). I met with Mark Johnson, Senior Engineer Technologist and Kristen Belisario, Environmental Permitting and Compliance(919-546-4005 office,440-668-8785 mobile). Mostardi Platt out of Elmhurst,Illinois was performing the source test for Piedmont. The testing company contact is Eric Ehlers, Director of Project Development,at(630)993-2663 (eehlers@mp-mail.com). The Project Supervisor for Mostardi Platt on the day of testing was Ryan Simon. c -7 'All xo 2W, g� 'W"Ir-A.,_v_ W11, JL,Mild" 00 Ty mg, gg- 00` A�l MEMO*i CIA` 'All gg MR MW Ev illo MI-R- W.M!, M, 'A N, "An R R �ON.

Test run 2 started at approximately 11:25 AM and ended at approximately 12:25 PM. Test run 3 started at approximately 12:40 PM and ended at approximately 13:40 PM. No problems were noted during the test runs. The engine run time hours at the start of the test were approximately 229 hours. I departed the facility after completion of Test run 3 at approximately 14:10 PM. The generator was connected to a heat sink load that allows full load operation. The generator was operating at a load of approximately 552 KW,or approximately 92%of full load. The load remained steady during the test runs. Typical field data and field calculations for the run were as follows(further analysis will be done prior to the final report submittal): , :;A, .,. ....:,;,=�z....,_.,. .-ram,='... .. -,." ..., ,. .....,... -a... ..>.... >,. ...,.;,,... ..., . . ,... ... . ...t�.';-"`.r ..r.".......,..,, .... .... ., i i Oz 7.9% i 8.0% 8.0% , COz 6.3% �� �6.3% _ �� 6.3 NOx 204�ppm 207 ppm 200 ppm Co 382 ppm-'--',—. -- pm 395 ppm 394 ppm F— VOC —'F' -- 14 ppm 15 ppm 15 ppm Mr. Ryan Simon, Project Supervisor(Mostardi Platt)provided the following preliminary facility data for all runs: .....A-ERAG l.! of j NOx 100 ppm 93.7 ppm 88.2 ppm 93.1 ppm CO 170 ppm 180.7 ppm 178.9 ppm m b_.179.0 ppm j VOC 12.1 ppm 8.3 ppm 8.2 ppm "8 9 ppm VIII. COMPLIANCE STATEMENT: It appeared that the stack testing for emergency generator engine(EGO I)was conducted in accordance with the requirements of the EPA methods specified during the stack testing on 05/10/2022. Final results will be submitted by the company and are due within 60 days after completion of the test,per the NSPS JJJJ requirements. /elj cc: FRO Facility Files 3 k`k'- 9 ,:.,, c'"'s„ _r. 3 -. •3:,er r-.Y� :_:.-� r .n�... ,-.+),. 3 -�,+�.. ..,..a. a ..u. £: .,c a,. -f-•:t .� ��•.:,, �F r. - ae' ra:, .L - .:, ..._ -.. rz..<.. :. :.'N`, ,-9,S F.:_,...-.3`=•T-..._ x ..:;n. ,-tic,^.. ,.. .:�.; v ?• -.C:. r`k E r. :i ;.a --.,... a�.ti..._.. .:._.. a -.,... ... ... ,,,.��?''r_.....-_:4, .._. ..-:>.' .>-..R ._., -2< L._.r,., a'4 ''11,' �-• _ 'F .--Z; �:4 Tn 'r+..- s ...'T., ..s_ ...�., 3 .._.'R.,- ..i„,....'{,'-1.. ,. _,..,,,,.>r .:.n..,u ,.'-,'..,r r cei-,r ..,' �v. •^4 ''� - ,•G.. :_-r.:,...,.+ ._.k .r ..<_,.>~:.r,i _--� ,�" �., >•a >n. ._ �' .- -, 4.
