Facility ID 0100237,Air Permit No.06740T20
Filterable Particulate Matter,Carbon Monoxide,Hydrogen Chloride,and Mercury
Emissions Testing of Wood Boilers Nos.B-2,B-3, and B-4
By TRC Environmental Corporation, October 9, 15, and 16,2018
DAQ Tracking No. 2018-247ST
TRC Environmental Corporation(TRC)performed EPA Method 5 for filterable particulate matter(PM),
EPA Method 10 for carbon monoxide(CO),EPA Method 26A for hydrogen chloride(HCl),and EPA
Method 30B for mercury(Hg)emissions from wood-fired boilers B-2,B-3,and B-4. The emissions test
results demonstrate compliance with the applicable regulations.
Boilers B-2 and B-3 are wood fuel-fired boilers(28.7 million Btu per hour heat input capacity each)
controlled by two multicyclones each. Boiler B-4 is a wood fuel-fired boiler(57.6 million Btu per hour
heat input capacity)controlled by two multicyclones and an electrostatic precipitator ESP-4. Testing was
performed to demonstrate compliance with 15A NCAC 2D .1109 1126) Case-By-Case Maximum
Achievable Control Pechnology(until May 19,2019). Boilers B-2,B-3, and B-4 are also subject to 40
CFR 60 Subpart Dc Standards of Performance for Small Industrial-Commercial-Institutional Steam
Generating Units and 15A NCAC 2D .0504 Particulates from Wood Burning Indirect Heat Exchangers.
The test results are expressed in pounds per million Btu(lb/mmBtu)and parts per million volume dry
corrected to 7%oxygen(ppmvd@7%02). The emissions test results for the three boilers are shown in
the tables below.

The average heat input rate during testing for Boiler B-2 was 24.9 mmBtu/hr and 26.5 mmBtu/b for
Boiler B-3. The average heat input rate during testing for Boiler B-4 was 38.4 mmBtu/hr. An HCl audit
sample was performed during this test and the results are acceptable. The emissions test results
demonstrate compliance with the applicable regulations. If there are any questions regarding this review,
