Proposed Particulate Matter,Hydrogen Chloride,and Mercury Emissions Testing
Of Unit 1 and Unit 2 Boilers
By Grace Consulting,Inc, Proposed week of June 24,2019
DAQ Tracking No. 2019-134ST
Dear Ms. Grace:
The North Carolina Division of Air Quality(DAQ)has reviewed the protocol submittal form(PSF)for
particulate matter PM),hydrogen chloride(HCl),and mercury(Hg)emissions testing of ES-1 (Unit 1)
and ES-2 (Unit 2). Grace Consulting,Inc. (GCI)proposes EPA Method 5 for filterable PM,EPA Method
26A for HCl, and EPA Method 30B for Hg. The proposed testing is acceptable to demonstrate
compliance with the applicable regulations.
ES-1 (ES-14A throughlC)and ES-2(ES-2-2A through 2C)are two electricity generating units
consisting of six identical watertube design coal/natural gas/No.2 and No.4 fuel oil/tire derived
fuel/pelletized paper fuel/flyash briquette/unadulterated wood/unadulterated biomass/adulterated resinated
wood/creosote treated wood-fired steam,electric generating boilers. Each boiler is controlled by a
bagfilter,rotating overfire air, furnace sorbent injection, and selective non-catalytic reduction systems.
The permitted nominal heat input is 223 million Btu per hour(mmBtu/hr)for each boiler.
The following regulations apply:
• 40 CFR 60 Subpart Db Standards of Performance for Industrial-Commercial-Institutional Steam
Generating Units(PM-filterable only)
• 15A NCAC 2D .0501(c) Compliance with Emissions Control Standards(PMio)
• 15A NCAC 2D .0530 Prevention of Significant Deterioration (PSD) [PM]
• 15A NCAC 02D .0530(u)PSD Projected Actual Emissions(PM/PMIo)
• 15A NCAC 02D .0614 Compliance Assurance Monitoring
• 15A NCAC 2D .1109, 1120)Case-by-Case MACT(PM,Hg,HCl)through May 19,2019

A summary of the test methods and emission limits is shown in the table below.

0.027 lb/mmBtu' 2D .0530
Filterable PM EPA Method 5 0.0184 lb/mmBtu 2D .053 u

0.0371b/mmBtu3
HCl EPA Method 26A 0.022 lb/mmBtu 63 Subpart DDDDD
Hg EPA Method 30B 5.7E-06 lb/mmBtu
I Emission limit is per boiler
2 Limit is in effect through May 19,2019
3 Limit starts May 20,2019
The PSF indicates"normal operating load"as target process operating rate. Based on the previous test
conducted August 2018, ES-1 averaged 194.5 mmBtu/hr heat input per boiler and ES-2 averaged 198.5
mmBtu/hr per boiler. The final test report should indicate similar operating rates. An HCl audit sample
is required for the EPA Method 26A testing and the sample should be available for inspection.
The proposed testing is acceptable to demonstrate compliance with the applicable regulations. Approval
of the protocol does not exempt the tester from the minimum requirements of the test methods. Any
deviations from the methods remain subject to approval by DAQ. If you have any questions regarding
this review,please contact me at(919)707-8427 or Brent.Hall ncdenr. ov.
