Introduction:
On August 25-27,2020,Mr. Thomas Gray, QSTI(I-IV),Environmental Specialist,of the Winston Salem Regional Office-Division of
Air Quality(WSRO-DAQ),contacted Ms.Kristie Hill,HR Manager,of Canfor Southern Pine-Graham plant,for the purpose of
observing stack testing being performed on the facility's wood fuel-fired boilers(B2,B3,134).All three boilers are each individually
controlled by two multicyclones and an electrostatic precipitator in series.The boilers have heat input capacities of 28.7,28.7 and 57.6
MMBtu/hour,respectively.Testing was required to demonstrate compliance with 40 CFR Part 63 Subpart DDDDD, "NESHAP for
Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters."listed in permit condition 2.2.C.1. Also,
Boilers B-2, B-3,and B-4 are subject to 40 CFR 60 Subpart Dc,"Standards of Performance for Small Industrial-Commercial-
Institutional Steam Generating Units,"listed in permit condition 2.1.A.4 and 15A NCAC 2D .0504,"Particulates from Wood Burning
Indirect Heat Exchangers,"listed in permit condition 2.1.A.1 (B-2 and B-3 only). Mr. Tyler Mills,of TRC Environmental Solutions,
1

was the leader of the test crew performing the sampling.Testing was conducted over the course of three days.Ms.Kathy Ferry,
Environmental Consultant for the facility,was also on site to aid in process data collection.
Previous Testing:
The facility previously conducted testing on Boilers 2-4 from September 10-12,2019.As detailed in the table below,Boiler 4
exceeded the filterable PM limit for both NSPS Subpart Dc and NESHAP 5D.However,using the weighted average and filterable PM
results from all three boilers,the facility was deemed in compliance with NESHAP 5D.After performing maintenance on the multi-
cyclone and ESP,the facility retested B-4 for filterable PM on January 30,2020.Results from that test indicated a filterable PM
emission rate of 0.01921b/mmBtu,in compliance with the filterable PM limit for both NSPS Dc and NESHAP 5D.

The PSF was forwarded to SSCB on June 11,2020 and subsequently approved by the SSCB on August 20,2020.No deviations
from the method were requested in the PSF.
Testing:
Testing commenced on August 25,2020 on Boiler 4.Method 1 criteria was met on each boiler,with maximum sampling points
being performed on each boiler(24 points).Boilers 2&3 each have stacks with 24"in diameter,with Boiler 4 having a stack
diameter of 36".To ensure minimum detection limits were met for the 30B sampling,and the minimum volume of 2 dscm were met
for filterable particulate as required by subpart DDDDD,test runs performed were 96 minutes in duration.Being that each stack had
two ports,and 24 points were being traversed,each point was sampled for 4 minutes each(96 minutes/24 points=4 minutes per
point).Methods 2 and 4 were performed in conjunction with the Method 5/26A train,and Method 3A for O2/CO2 and Method 10
for CO were completed using a CEMS system.All methods will be discussed in greater detail below.

Method 5/26A-
The Method 5 and Method 26A sampling were performed in conjunction with each other.TRC used a Teflon filter support,glass
probe liner/nozzle,and probe and filter bell temperatures were maintained between 248-273 degrees Fahrenheit to meet the
requirements of both Method 5 and Method 26A. The Method 5/26a testing was performed by sampling the stack gas isokinetically
with the filterable pm being captured in the front half M5 filter,the hydrogen halides being captured in the acid impingers(charged
each with 100 mL 0.1 N H2SO4),and the halogens captured in the basic impingers(each charged with 100 mL0.1 N NaOH). It should
be noted the testers used a split train, in which a jumper was used from the filter box to the first impinger. Following the sampling,and
the post run leak check,the probe,nozzle,and front half filter bell were rinsed and brushed in triplicate with acetone and captured in a
250 mL amber sample bottle.The jumper used during the testing,was rinsed with DI water to ensure all sample was recovered in
impingers.The front half prepared M5 filter was then recovered and sealed in a labeled petri dish. Both the acetone rinse and filter
will be analyzed by gravimetric analysis. The impingers were then weighed gravimetrically for moisture analysis(M4).Then the
back-half filter bell, as well as the acid impingers and connecting glassware,were rinsed with 100 mL 0.1 N H2SO4 and combined in
a 1000 mL PE bottle for analysis by IC(Ion Chromatography).The same recovery was performed for the basic impingers,however
using NaOH. Mr. Gray discussed with Mr. Mills that HC1 analysis was only required,Mr.Mills stated they would be archiving the
NaOH samples. At the time of the testing,no audit samples for HC1 were required.Per the EPA emission measurement center
technical support page,"the general provisions to 40 CFR Parts 60 and 63(see §60.8(g)(1)and§63.7(c)(2)(iii)(A))require that the
owner or operator obtain audit samples if the audit samples are"commercially available"and have defined"commercially available"
as two or more independent accredited audit sample providers(AASP)to have blind audit samples available for purchase." Since there
are no longer two providers,the requirement to obtain these audit samples is no longer in effect until such time as another independent
AASP has audit samples available for purchase.".The meter box utilized for this portion of the testing had a gamma of 0.9909,and a
delta H @1.924.As mentioned in the introduction, Subpart 5D requires a minimum volume of 2 dscm to be sampled during
particulate runs. Being that the runs were only 90 minutes in duration,Mr.Gray ran the preliminary method 5/26A data through
spreadsheets to confirm a minimum corrected volume of 2dscm was sampled. Isokinetics were also verified and were within the
method allowance of 90-110%for all the boilers.
Method 30B-
Method 30B for elemental and oxidized mercury(Hg)was also performed on the three boilers.Method 30B was performed by
extracting a known volume of stack gas through paired in stack carbon sorbent traps,using a heated 30B sampling probe(heated
sufficiently to prevent condensation in traps).The method required paired train sampling to determine measurement precision and
verify validity of test results. The method requires a field recovery test which assesses the recovery of an elemental Hg spike with a
(90-110)%spike recovery required for run validation. Each sorbent trap consists of two separate carbon sections for breakthrough
analysis.The method requires under normal circumstances that breakthrough be less than 10%of the front half value,for the run to
be considered valid. Paired traps are also required to have a relative deviation(RD)of less than 10%for Hg concentration
<0.1 µg/dscm,and less than 20%RD for Hg concentration<.20 µg/dscm.Also,total sample volume must be within 20%for the A
side and B side respectively. 30B sampling was performed on all 3 boilers with an ESS instruments 30B box that had an A side
gamma of 1.0117 and a B side gamma of 1.0211.B side spiked tubes(provided by Ohio Lumex)had a concentration of 50 ng,with
the average sampling rate for both sides being I LPM,with a final target volume of 96 L.As mentioned above,test runs were 96
minutes in duration to ensure the minimum detection limits of the method were met.All leak checks were observed and were well
within the method allowance of 4%of the total sampling rate(0.04 L),and conducted above the highest vacuum achieved during
the run.The 30B sampling probe was heated well above point of saturation,with trap temperatures on average around 260 degrees
Fahrenheit. Silica canisters were used for moisture knockouts before the sample was subsequently conveyed to the 30B box.

Methods 3A and 10-
Method 3A for O2/CO2 and Method 10 for CO were performed in conjunction with the above-mentioned methods on all 3 boilers.
Stack gas was extracted through a heated CEMS probe through an out of stack filter,followed by a heated sample line(maintained
248 degrees Fahrenheit plus)to a sampling conditioning system,were it is dried before entering the analyzers.All direct
calibrations,bias,and drift checks were within method allowances(Direct Cal<2%of span,bias<5%of direct cal response,drift
<3%of initial bias and final bias).All calibration gases were verified as EPA protocol 1 gases,with expiration dates on all gases
verified to be within range.A CO span of 2216 PPM CO was used on all three boilers,with an O2/CO2 span of 21.9 and 18.67,
respectively,also used.No deviations from the methods were observed during the testing of all three boilers.Calibration data and
bias information are provided in the NC DAQ CEMS Observation checklist provided below.A stratification check was conducted
during run 1 on each boiler.Results from the stratification check indicated a less than.5%deviation at each point using 02, allowing
single point sampling at the centroid of the stack for the remainder of the runs.

Process Information:
Process information for each boiler was recorded every 15 minutes which included the following parameters: steam pressure,steam
flow,sawdust reading count,multicyclone OP,and opacity(measured by COMs).Fuel samples were taken from the fuel feed at the j
beginning of each run.These samples will be sent to the lab for Fuel analysis to calculate a BTU value.Preliminary calculations
indicated the facility was around 85-90%maximum steam flow for the boilers as 3 run average for Boilers 2,3,and 4 were 87.4,
87.6,and 89.4%of their maximum rated steam flow,respectively.Being that the boilers are equipped with electrostatic
precipitators,primary and secondary voltage readings were also recorded for Fields 1 (B2-B4)and Field 2(B4 only).
