112j Case-by-Case MACT Emissions Testing for Boilers Unit 1 and Unit 2
Submitted by Grace Consulting, Inc.
Proposed Test Date: Week of August 13, 2018
Tracking No. 2018-173st
Dear Ms. Grace:
The North Carolina Division of Air Quality(DAQ)has reviewed the protocol submittal form
(PSF) for the testing of the ES-1 and ES-2 boilers. The proposed testing is acceptable to
determine the particulate (PM),particulate matter less than 10 microns(PM10),hydrogen
chloride(HCl), and mercury(Hg) emissions for 112j Case-by-Case Maximum Achievable
Control Technology(MACT) compliance purposes.
The sources to be tested are ES-1 (Unit 1) and ES-2 (Unit 2). Unit 1 and Unit 2 are two
electricity generating units each consisting of three coal/natural gas/No. 2 and No. 4 fuel oil/tire
derived fuel (TDF)/pelletized paper fuel/flyash briquette/unadulterated wood/unadulterated
biomass/adulterated resinated woo&creosote treated wood-fired steam, electric generating
boilers, ES-14A, ES-14B and ES-14C (Unit 1) and ES-24A, ES-24B and ES-24C (Unit 2).
The permitted nominal boiler heat input is 223 million Btu per hour, each. Each boiler is
controlled by a bagfilter, a rotating overfire air system, a furnace sorbent injection system, and a
selective non-catalytic reduction system.
Grace Consulting has proposed the test methods as outlined in Table 1 to demonstrate
compliance with the applicable emissions standards and limitations as detailed in Table 2.

CPI proposes operating the six boilers at"normal operating load" during testing. Current
operation is 360,000 to 500,000 pounds of steam per hour. The proposed fuel mix for testing is
coal (10%-15%), TDF (35%-40%) and wood(45%-50%). The proposed test methods and
conditions are acceptable. The PSF indicates that the required audit sample analyses will be
performed in conjunction with the proposed testing. The audit sample must be on-site and
available for inspection by the DAQ observer. For additional audit information see
www.epa.gov/emc/emc-technical-supportftaudit.
Approval of this sampling protocol does not exempt the tester from minimum requirements of
the test methods. Any deviations remain subject to approval by DAQ. If you have any
questions,please contact me at 919-707-8416 or shannon.vo el ncdenr.�g�ov.
Sincerely, Yrom-nental
