RE. Title VA nnual Ozone Season Nitrogen Oxide Emissions Report—Permit No. 10097T
Piedmont Natural Gas-- Wadesboro Compressor,Anson County
Facility ID: 0400056
Dear Ms. Carter:
Piedmont Natural Gas, Inc.(Piedmont)is submitting nitrogen oxide emissions during the 2021 ozone
season for the Wadesboro Compressor Station located at 379 Pleasant Grove Church Road in
Wadesboro, Anson County,North Carolina. These compressors, which operate under North Carolina
Division of Air Quality(DAQ)Permit No. 10097T, burn natural gas exclusively.
As stated in permit condition 2.LAAX,the facility is required to submit a report by October 31"of
each year documenting the total nitrogen oxide emissions from May 1 to September 30. This letter
serves as the annual ozone season nitrogen oxide emissions report for 2021.
A table listing the nitrogen oxide emissions for each of the internal combustion engines at the facility
is attached. Four(4)of the eight(8)permitted four-cycle lean burn internal combustion reciprocating
engines have not yet been installed at the Wadesboro Compressor Station. Therefore,there were no
emissions during the reporting period from these units. In addition,the emergency generator(EGO 1)
has a maximum horsepower rating below the requirement for this rule. Therefore,no emission data
for EGO1 is included.
As the responsible official, I certify that based on information and belief formed after reasonable
inquiry,the statements and information in the document are true,accurate,and complete. if you have
any questions,please contact Kristen Belisario at(440)668—8785 or via email

Sincerely,
