Subject: Piedmont Natural Gas, Wadesboro
Air Permit No.I0097R00, Facility ID 0400056
Proposed Performance Test for ID COM1101-COMP04,NG-fired engines
Proposed Test Date: February 7, 2014
DAQ Tracking No. 2014-007ST
Dear Mr. V 1 nzani:
North Carolina Division of Air Quality(DAQ)has reviewed the protocol submittal form(PSF)
for the subject testing and deemed it acceptable. The sources are 4-stroke lean burn natural gas
engine compressor engines rated at 4735 horsepower(hp). The proposed testing is the initial
performance testing required by applicable regulations for new sources.
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 non-
emergency engines constructed after July 1, 2010.

The proposed test methods are acceptable for the specified pollutants. Approval of the protocol
does not exempt the tester from the minimum requirements p q ements 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 3A, 4, 7E, 10, 18, and 25A.
Testing must be conducted at full load f 10%. Testing proposed operating process rate of 4735 hp
is acceptable. If you have questions,please contact me at(919) 707-8413 or
