Dear Mr. Groves,
The Division of Air Quality(DAQ)has received the subject reports(CEMCR and EER) submitted by
The Capital Power Corporation in a letter dated January 27,2017.The reports were submitted for the
continuous emission monitoring system(CEMS)and continuous opacity monitoring system(COMS)
operating on electric generating Unit 1 and Unit 2,each consisting of three Boilers with the common
stack.
DAQ has reviewed the quarterly EERs for the ending December 31,2016. The percent excess emissions
(%EE)and percent monitor downtime(%MD)are summarized as follows:

A review of the quarterly excess emissions reports(EER) indicated there were no violations of the
applicable emissions standards.Please note that the S02 excess emissions of 48.12% and 40.13%for the
Unit 1 and Unit 2 are addressed in the Special Order by Consent(SOC 2016-001) signed on June 24,
2016 The other excess emissions noted above are excused pursuant to the applicable regulation. Please
note that each exceedance of the emission control standard unless excused by applicable regulation can be
credible evidence of a violation consistent with 40 CFR 60.11(g).
The reports were also reviewed with the general provision of 40 CFR 60.11(d), and 40 CFR 60.13 to
assess good operation and maintenance(O&M)practices for the facility and monitoring systems.As
summarized in the table on the previous page, the emission units and associated CEMS/COMS
appeared to have operated using good O&M practices since quarterly percent excess emissions(%EE)
and percent monitor downtime(%MD)were less than 3% for two consecutive quarters and 6%for any
single calendar quarter.
The CGA(NO., S02 and CO)result for the Unit 1 and Unit 2, conducted during fourth quarter were
within 15%specification given in 40 CFR 60,Appendix F.
The opacity monitor appears to meet the requirements of QA/QC rule(40 CFR Part 60,Appendix F,
Procedure 3).
If you have any questions,please contact me at(919) 707-8409 or samir. arekh ncdenr. ov.
