The reports were reviewed for compliance with the applicable emission standards. There are opacity
excess emissions attributed to the"other known causes"during first quarter for the Unit land Unit 2.
Please note that these excess emissions are not excused pursuant to 40 CFR 60, Subpart A, and Subpart
Db. These unexcused excess emissions prevent you from certifying compliance in your Annual
Compliance Certification(ACC)for the calendar year 2020 pursuant to 15A NCAC 02Q .0508.
The other excess emissions noted above are excused pursuant to the applicable regulation.Please note
that the SOz excess emissions of 24.61% and 37.70%for the Unit 1 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).
In our e-mail dated June 4,2020,we requested to revise%MD for the first quarter. As you are aware
from our multiple communication that there is a software error with your data acquisition and handling
system(DAHS). It appears that DAHS under-reports the %MD for the applicable emission unit.
Ms. Ginny Grace of your staff in her e-mail dated July 15,has indicated that%MD issue should be
corrected in the second quarter reports.We will wait until the second quarter reports before making a final
review of the first quarter reports.
Also,please ensure that the DAHS is corrected for the Roxboro facility.
The CGA(NOx, SOz and CO)result for the Unit 1 and Unit 2, conducted during first 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. hi 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.parekligricderingov.
Sincerely,
Samir Parekh,P.E.,Environmental Engineer
