a. The Permittee shall use a continuous opacity monitoring system. (COMS) to monitor and record opacity, and a
continuous emissions monitoring system (CEMS) to monitor and record Sulfur Dioxide (SO,) emissions. Continuous
emissions monitoring and recordlceeping of opacity shall be performed as described in Paragraphs 2 and 3.1.1 through
3.1.5 of Appendix P of 40 CPR Part 5I.. Continuous emissions monitoring and recordlceeping of SO?, shall be
performed as described in Paragraphs 2 and 3.1.3 through 3.1.5 of Appendix P of 40 CFR Part 51. The monitoring
systems shall meet the minimum specifications described in Paragraphs 3.3 through 3.8 of Appendix P of 40 CPIZ Part
51.
b. Compliance with the sulfur dioxide emission standard is determined by averaging hourly continuous emission
monitoring system values over a 24-hour block period beginning at midnight. To compute the 24-hour block average,
the average hourly values are summed,and the sum is divided by 24. A minimum of four data points,equally spaced, is
required to determine a valid hour value unless the continuous emission monitoring system is installed to meet the
provisions of 40 CFR Part 75. If a continuous emission monitoring system is installed to meet the provisions of 40 CPR
Part 75,the minimum number of data points are determined by 40 CPR Part 75.
c. The quarterly excess emissions (EE) reports required under Appendix P of 40 CPR Part 51. shall be used as an
indication of good operation and maintenance of the electrostatic precipitators. These sources shall be deemed to be
properly operated and maintained according to the following requirements. For opacity, the percentage of time,
calculated on a 6-minute average, in excess of 40 percent (including startups, shutdowns, and malfunctions) does not
exceed 3.0 percent of the total operating tome for any given calendar quarter, adjusted for monitor downtime (MD) as
calculated below. In addition, these sources shall be deemed to be properly operated and maintained if the%,MD does
not exceed 2.0 percent. SO2 emissions in excess of 0.56 pounds per million Btu calculated on a 24-hour basis shall be.
deemed a violation of good operation and maintenance standards.

I. Purpose of Application:
Duke Energy Carolinas is requesting a modification to the Marshall Steam Station's current air permit to
conduct a short-term trial test study to evaluate the effectiveness of liquid calcium di-bromide (sorbent) on
the control of mercury emissions on Units I and 2. The study will be conducted over a two week period
where the calcium di-bromide(CaBr2) solution will he spray-applied to the coal going into tlae boilers at a
rate ranging from 0.25 —2.5 Ibs/tort of coal. Approximately 30,000 lbs of liquid CaBr2 (53% solution by
weight) will be spray-applied onto approximately 37,500 tons of coal. Mercury emissions before and after
the test will be monitored using a spectated mercury CEM.
This study is similar to a study on Marshall Unit 4 in the fall of 2010, where CaBr2 and powdered activated
carbon were both used to determine the effects on mercury emissions; except powdered activated carbon is
not being used for the Units I and 2 study.
Even though, as shown below, emissions are expected to be welt below PSD significance, Duke has
requested (permanent) PSD and NSR avoidance conditions rather than a condition under 2D .0530(u) only
requiring five years of reporting to determine if the change results in a significant PSD net emissions
increase. At this tune the change is for a short-term study and Duke states that if they pursue this sorbent
injection long term, they would reapply and,justify a change in the permit language based on data gathered
1

during the trial test. If they do not pursue sorbent injection long-term, they could apply to have the PSD
avoidance condition removed.
This is a significant Title V permit modification pursuant to rule 15A NCAC 2Q .0501(c)(2). Duke roust
subunit a Title V application for the changes made to permit Sections 2.EA.16 and 2.I.A.17 on or before^ 12
months after commencing operation. The permit shield described in General Condition R does not apply to
these changes.

IV. Summary of Changes to Emission Sources and Control Devices
There are no chances to emission sources or control devices_
V. Emission Evaluation
During combustion, vapor phase mercury in the coal along with the Ca Bi-2 will form HgBr and ILBr,,
which will adhere to the f7.yash and will he captured by the ESP with additional control provided by the wet
FGD. The calcium. may .reform as CaSO4, CaO2, or CaCO; which is a potential increase in particulate
emissions.
Duke has furnished what they say is a conservative(overestimated)calculation of the potential increase in
PM, PM10 and PM2.5 emissions from Ca compounds as shown below.
Assumptions: Total amount of CaBr2 during study: 30,000 lbs
Study to last 10 days at 24 lt.rs/day
Coal ash content 11%(front 2010 average fuel analysis)
Unit l and 2 heat input: 4230 anmBtulhr each
Coal usage(potential): 171 tons/hr each unit
Two cases were considered, one based on maximum coal usage at potential operating conditions and one
based on expected actual average Units 1 and 2 coal usage(worst case):
2

Maximum coal use during test period: 10 days x 24 hrslday x 171 tons/hr x 2 units = 92,080 tons
Actual average Units I and 2 combined coal burn for 10 days in September 2010=37,500 tons
Conservatively assume all CaBr2 is converted to CaSO,,, Tlsen using the molecular weights:
Molecular wt. CaBr2= 199.88
Molecular wt. CaSO,.= 136.14
Each lb CaBr2 forms: CaSO4/CaBr2= 136.141199.88 =0.6811 Ihs of CaSO,j which adds to particulate
emissions.
Mass of ash in coal:
maxi.cn.urn: 82,080 tons x 2,000 lb/ton x 0.11 = 18,057,600 lb ash
expected (worst case): 37,500 tons x 2,000 lb/ton x 0,11 = 8,250,000 lh ash
Amount of ash increase=30,000 lb CaBr2 x 0.6811 lb CaSO41 lb CaBr,-20,430 Ih CaSO
In percentage terms:
maximum: 20,430 lbs CaSO4/ 18,057,600 lbs ash=0.1 1.3% increase
expected (worst case) 20,430 lbs CaSO4/8,250,000 lbs ash=0.248%increase
Current stack PM emissions are<0.03 lb/minBtu (post FGD PETS),therefore the increase is:
maximum: 0.03lb/mmBtu x 0.00113 =0.000034 lb/mmBtu PM
expected (worst case): 0.031b/mnnBtu x 0.00248= 0.000074 lblmmBtu PM
The worst-case increase in PM emissions is:
0.000074 lblmrnBtu x 4230 mmBtu/hr x 2 Units=0.63 lbs/hr
0.63 lbslhr x 10 days x 24 hrs/day 151.0 lbs
PM = 151.0 lbs/2000 lbs/ton-0,0754 tons PM.<25 tpy PSD threshold
Assume PM 10 is 90% of PM::
PM 10 =0,0754 tons PM x 0.90= 0.068 tons PM10< 15 tpy PSD threshold
...... .... ... .. ... .....
Assume PM2.5 is 29% of PM:
PM2.5 0.0754 tons PM x 0.29=0.022 tons PM2.5 < 10 tpy PSD threshold
Therefore,the above PM,PM10 and PM2.5 emissions are below PSD significance.
Long-term Potential Emissions If Permitted Based on 8760 lirs
For information, even though Duke is not seeking a long-term permit at this time, potential emissions based
on operation at 8760 hrlyr would still result in emissions below PSD significance of-,
PM: 0.63 lb/hr x 8760 hrlyr=5519 lblyr/2000 lb/ton =2.76 tpy PM
PM 10: 2.76 tpy x 0.90=2.48 tpy PM10
PM2.5: 2.76 tpy x 0.29=0.80 tpy PM2.5
Vt, Regulatory Evaluation
2Q.0317 to avoid apVIicability of 2D .0530
This condition stipulates that the amount of spray-applying calcium dibrornide used in the Units 1 and 2
boilers (ID Nos. ES-1 and ES-2) during the mercury control evaluation study shall not exceed 30,000 tbs.
This limit will prevent the particulate emissions as calculated above from being exceeded. The amount of
calci.uan dibrom.i.de used is to be reported after completion of the mercury control study.
3

20317 to avoid applicabi lily_Qf 2D 0531
Since Catawba County is currently in non-a.ttainrnent for i'M2.5, a separate-NSR condition is required for
PM2.5 emissions. The same CaBrz limits and reporting in the above PSD avoidance condition apply for
this condition..
2D .053G
Based on the recent particulate emission test showing emission rate below 0.03 lb/mmf3tu, the PM
emissions after this modification can be estimated as follows: = 0.03 lb/mmBtu 0.000074 lb/ninit3tu
0_030074 lb/million Btu, which is much less than the SIP limit of 0.20 lb/million Btu, `therefore,
compliance is expected.
Tox.ics
Duke has supplied the M:SDS for CaBrz. A concern at the tithe the Unit 4 CaBrz mercury control study was
permitted was the possibility that thermal decomposition products from the CaBr, may include toxic or
corrosive fumes of hydrogen bromide and/or bromine.
Bromine is a regulated potlutant under 2Q .0700. In addition, the spray-applied coal is burned at high
temperatures in the boiler, so the possibility of thermal decomposition of the sorhent, and formation and
emission of bromine was addressed_
Duke investigated this issue and offered the following:
After combustion at > -500 W. bromine will leave the WFCD as ba-omide._.Thus, most of the
bromine added to the coal as CaBr, is leaving a limestone-based WFGD once again as C al3r,
with its off water, Only a vet y small amount is emitted at the stack as FIBr (< 1 mg 118r/asem),
but not as bromine.
Halogen measurement methods (M20) are not sensitive enough to detect the levels of
concentration you (Bill H.) tiled for AIC requirements. Any halogen emitted at the stack is likely
to be HBr and not Brz, and HBr will be below detection limits. The practical detection limit for
bromides at the stack using M26 is—0.04 ppin. At the detection limit, it would be very difficult io
determine what the accurate speciation may be, The NC TPLR Level for bromine of 0.054
lb/hr is about 0.003 pprn for Marshall[Unit 4] (tissume 700 M[Ve), tis�al helow the 0.04 pprn
detection limit for bromides via M26. In addition, two EP.RI reports (not yet published)support
this stal'eaaaent and show bromides at the stack to he below detection limits by all practical
;purposes. These reports have not been o{fcrally published and are confidential tit tl�zs time.
After reviewing this issue, DAQ concluded that the formation and emission of bromine (Br2) is not
expected and therefore air toxics do not apply.
