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 41.90% and 49.97%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).
The CGA(NOx, SOz and CO)result for the Unit 1 and Unit 2, conducted during third 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
