Protocol for Filterable,Particulate Matter, Condensible Particulate Matter;�'and Sulfur
Dioxide Emissions Testing of Hog Fuel Boiler No.I by TRC Environmental, Inc.
Proposed Test Date: Week of July 15, 2013
Tracking No. 2013-113ST
Dear Mr. Wynne:
The North Carolina Division of Air Quality (DAQ)has reviewed the protocol submittal form
(PSF)for emissions testing of filterable and condensible particulate matter(PM) and sulfur
dioxide(SO2). The source to be tested is the Hog Fuel Boiler No. 1 (ID No ES 64-25-0290),
which combusts hogged fuel, lignin, sludge distillate and residual fuel oil, and natural gas. In
addition, the boiler serves as a backup destruction device for the combustion of high volume, low
concentration non-condensible gas (HVLC NCG). Emissions from the boiler are controlled by a
primary and secondary multicyclone (I.D.Nos. CD-64-45-0100 and CD-64-45-0230,
respectively) and then by three parallel electroscrubbers (I.D. Nos. CD-64-60-0120, CD-64-60-
420, CD-64-60-0720). The proposed test is being conducted as a requirement of the permit after
lignin has been added to the fuel mix. The protocol requests that the test be conducted with the
use of natural gas in place of or in addition to oil to reflect future operations of this boiler with
supplemental natural gas. The proposed testingis's acceptable only as discussed below.
Testing will be performed in order to meet the permit requirements and emission limits:

The maximum permitted process rate is 1,021 million BTU/hr(MMBtu/hr) when firing any
combination of fuels. The normal process rate is between 200 to 375 thousand pounds of steam
per hour. The target rate is 250 and 350 thousand pounds of steam per hour. The proposed
process rate is acceptable. Process monitoring will be provided by the mill's information system,
IP21, Process Explorer. The PSF includes an indication that higher sample volumes will be
measured and therefore larger nozzle diameters will be used. This is acceptable.
The final test report should include the actual process rate data during the emission tests as well
as any control system parameters such as voltage across the electroscubbers. The test report
should clearly identify the test results as being representative of normal operations. One nm
must include sootblowing
In conclusion, the proposed test methods are acceptable. Approval of the testing protocols 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 the results
of this review,please contact me at(919) 707-8413 or at ary.saunders n,nedenngov
Sincerely,
