Proposed Particulate Matter,Hydrogen Chloride, and Mercury Emissions Testing
Of Unit 1 Boilers
By Grace Consulting,Inc,June 26,2019
DAQ Tracking No. 2019-134ST
Grace Consulting,Inc.performed EPA Method 5 for filterable particulate matter(PM),EPA Method 26A for
hydrogen chloride(HCl),and EPA Method 30B for mercury(Hg)emissions from Unit 1 boilers. The
emissions test results demonstrate compliance with the applicable regulations.
Emission source ES-1 is an electricity generating unit consisting of three 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(ES-14A through 1C). 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. Testing was performed at the common stack for the boilers.
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(PM Io)
• 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
• 40 CFR 63 Subpart DDDDD National Emission Standards for Hazardous Air Pollutants for Major
Sources:Industrial, Commercial, and Institutional Boilers and Process Heaters
• NCGS 62-133.8(g)Senate Bill 3 (SB3)State Best Available Control Technology(BACT)
[PM10/PM2.5,Hg]
The emissions test results and limits are shown in the table on the following page.

Unit 1 boilers averaged 623 mmBtu/b during testing or 93%of maximum and this operation rate is
acceptable. An HCl audit analysis was conducted during testing and the results are acceptable. The emissions
test results demonstrate compliance with the applicable regulations. If there are any questions regarding this
