Subject: Piedmont Natural Gas,Wadesboro
Air Permit No.10097TO1,Facility ID 0400056
Proposed Performance Test for ID EG-01,NG-fired engine
Proposed Test Date: May 12, 2016
DAQ Tracking No.2016-087ST
Dear Mr.Vinzani:
North Carolina Division of Air Quality(DAQ)has reviewed the protocol submittal form(PSF)for the
subject testing and deemed it acceptable. The source is a 4-stroke lean burn natural gas engine emergency
generator rated at 804 horsepower(hp). The proposed testing is the periodic performance testing required
by applicable regulations for new sources every three years or 8,760 hours,whichever comes first. The
engine has not operated for 8,760 hours and this test will meet the third year requirement.
Applicable regulations:
• 40 CFR 63 Subpart ZZZZ National Emissions Standards for Hazardous Air Pollutants for
Stationary Reciprocating Internal Combustion Engines(RICE NESHAP)
• Permit including Section 3.0 General Conditions Section JJ General Emissions Testing and
Reporting Requirements
• 15A NCAC 2D .2600 Source Testing
• 40 CFR 60 Subpart JJJJ,Standards of Performance for Stationary Spark Ignition Internal
Combustion Engines
The primary purpose for testing is to demonstrate compliance with 40 CFR 60 Subpart JJJJ. Compliance
with 40 CFR 63 Subpart ZZZZ is met by complying with the emission limits in 40 CFR 60 Subpart JJJJ.

The following emission standards apply to new spark ignition, lean burn burn gas-fired engines
constructed after July 1, 2010.
Table 1: NSPS,40 CFR Part 60, Subpart JJJJ Standards for 4-stroke lean burn natural gas-fired
emergency engines> 130 h
Pollutant Emission Standard(g/h -hr) -or- Emission Standard(ppmvd at 15%02)
NO, 2.0 g/hp-hr 160 ppmvd at 15%02
CO 4.0 g,'hp-hr 540 ppmvd at 15%02
VOC 1.0 g/hp-hr 86 ppmvd at 15% 02
g/hp-hr= gramihorsepower-hour; ppmvd=parts per million by volume, dry basis

The proposed test methods are acceptable for the specified pollutants. Approval of the protocol does not
exempt the tester from the minimum requirements of the applicable methods and 60 Subpart JJJJ
requirements. Since no deviations from the applicable testing methodology were addressed in the test
protocol,the testing should be conducted in strict accordance with the requirements of EPA Methods
2,3A, 4, 7E, 10, 18, and 25A.
Testing must be conducted at full load f 10%. Testing proposed operating process rate of 804 hp is
acceptable. If you have questions,please contact me at(919) 707-8413 or gary.saundersCancdenr.gov.
