Dear Mr. Hayward,
The Division of Air Quality(DAQ)has received the subject reports (CEMCR and EER) submitted by
The Capital Power Corporation in a letter dated July 27, 2020. The reports were submitted for the
continuous emission monitoring system(CEMS)and continuous opacity monitoring system(COMS)

stack.
DAQ has reviewed the quarterly reports for the period ending June 30,2020. The highest 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. The other excess emissions noted above are excused pursuant to the
applicable regulation.Please note that the S02 excess emissions of 40.22%and 61.35%for the Unit I
and Unit 2 are addressed in the Special Order by Consent(SOC 2016-001)signed on June 24, 2016
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).
Please note that emission limits specified in permit condition 2.1.A.I O.g are on a per boiler basis.
Therefore,please submit the EER for CO limit of 720 ppm by volume on a dry basis corrected to 3
percent oxygen 30-day rolling average, on a per boiler basis instead of a common stack.
Also,please submit the EER for the opacity operating limit specified in permit condition 2.1.A.I O.h.
The CGA(NOx, S02 and CO)result for the Unit 1 and Unit 2, conducted during second 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).
Due to COVID-19 restrictions on DAQ staff and our office operations,the mailing of this letter may be
delayed. In the meantime, an electronic copy(e-copy)is being provided for your records. If you should
have any questions,please contact me at(919) 707-8409 or samir.parekligncderingov.
