Monitoring and Recol'dl<eeping 1hqui•·cmcnts 

6. Ammonia: 

6. I. Ammonia emissions for compliance will be monitored by menns of periodic emissions 

testing utilizing Bny Area Air Qunlity Management District (BAAQMD) Method STI n 

or Environmental Protection Agency Conditional Test Method 027 (CTM-027). 'I he 

sampling point will be in the stack following the wet scrubber. Stack testing shnll occur 

on the following frequency: 

(J.l.l. Testing shall occur once each calendar quarter, with no consecutive tests less than 

80 lll' more than II 0 cnlendar days npnrt. 

6.1.2. 1!'3 consecutive tests arc each less than the ammonia limitation, then the tcstiug 

fi·equcney reduces to once every 6 calendar months, provided the nitrogen oxides 

emission limit is complied with during the test. 

Final 2011 Updates Supplernenll-36 

(d) EPA-Approved State of Washington Source Specific Requirements Page 96
TransAlta Centralia Gcncrntion LLC 

Page 7 of II 

6.1.3. If, nftcr there arc 3 consecutive tests less than the ammonia limitation, the next 2 

consecutive ksts are less than 50% of the ammonia emission limitation, then the 

testing frequency reduces to once annually, provitkd the nitrogen oxides emission 

limit is complied with during !he tests. 

6.1.4. If at any lime there is a test showing emissions above the emission limitation, then 

lhe testing rrcqucm.:y reverts to quarterly until the requirements in Conditions 

6.1.2 and 6.1.3 me met. 

6.1.5. The ammonia concentration measured during the periodic emissions testing is the 

30 opernting day rolling average value used for compliance starting on the date of 

the completion of the test unlil the completion of the next required periodic 

emission tesl. 

6.1.6. During the ammonia testing using BAAQMD tvlethod ST1 B (or CTl\·1-027), the 

30 rolling ammonia emission limit is to be treated as an hourly average for the 

purpose or Conditions G.l. and 6.2. 

6.2. For usc <IS a routine indicator orcompliant:c between the tests required in Condition (i, 1, 

ammonia emissions will be estimated. The estimate will be based on a calculation which 

uses as inputs the reagent concentration and tlow rate, a calculation or measurement of 

the uncontrolled nitrogen oxides rate, the continuous nitrogen oxides monitoring results 

measured in the stack, and other pnrameters as necessary. 

6.3. At TransAlla's option, an ammonia continuous monitoring system may be used instead 

of periodic emissions tests. A continuous ammonia monitoring system used for 

compliance must meet the monitor location requirements contained in 40 CFR Part 60 

Appendix 11, Pcrf<Jrmancc Specification l or 2, and the qunlity assurance and quality 

control requirements of 40 CFR Part 60 Appendix F as applicable. 

7. Nitrogen oxides monitoring ant! averaging 

7 .I. For any hour in which coal is com busted in a unit, the owner/operator or each unit shall 

calculate the hourly nitrogen oxides concentration in lb/MMBtu at the CEMS installed in 

accordance with the requirement~ o1'40 CFR Part 75. The 30-day average lb/MMIHu 

rate is calculated by summing the hourly emissions in pounds (unit lb/MMHtu times unit 

heat input) from all opcrnting units and dividing that by the sum or the hourly heat inputs 

in million Btul<.w all operating units. At the end of each boiler operating day, the 

owner/operator shall calculate and record ll ncw 30-day rolling average emission rate in 

lb/MMBtu from nll valid hourly data for tbat boiler operating day and the previous 29 

successive boiler operating dnys. 

7.2. ). An hourly average nitrogen oxides emission rate is valid only if the minimum number 

of data points, as spccilicd in 40 CFR Part 75, is acquired as necessary to calculate 

nitrogen oxides emissions and heat rate.

7.3. Data reported to meet the requirements of this section shall not include data substituted 

using the missing data substitution procedures of subpart D of 40 CFR part 75, nor shnll 

the data have been bins adjusted according to the procedures of 40 CFR pnrt 75. 

7.4. A boiler operating day is a 24-hour period between 12 midnight and the following 

midnight during which coal is com busted at any time in the boiler. It is no\ necessary for 

coal to be combustcd for the entire 24-hour period. 

S. Ammonia emission limitation compliance based on periodic slack sampling and parameter 

monitoring. 

R.I. Compliance with the ammonia emission limitntion is demonstrated by meeting the 

limitation dt~ring the stack testing pcrioJ. The average of the 3 discrete sampling nms 

will be used to determine compliance with the <Jmmonia emission limitation until the 

next periodic stack testing occurs. 

8.2. During each Ill~riodic stack test on t:ach boiler, the ummonia or urea reagent injection 

rate <Jnd the ammonia to nitrogen oxides ratio for each sampling nm shall be determined, 

recorded and reported as part ofthc testing report. 

R.3. During plant opcration between pcl'iodic stack testing, compliance with the ammonia 

emission limitation will be indicated by: 

X.J.l. Injecting <Jmmonia or men reagent at the injection rate tor ammonia or urea 

reagent used dming the most recent stack sampling at the appropriate operating rate; 

and 

8.3.2. Meeting the nitrogen oxides emission limit. 

9. Coal Quality Monitoring 

9.1. Coal nitrogen and sulfur content will be determined by taking a sampk of the coal from 

the transfer belts between the coni pile and coal silos. An alternate location that provides 

a sample representative of the coal !ired by the boilers may be proposed to Ecology hy 

TnmsAltn for approval ror usc. 

9.2. J\ sample ofconl ror nitrogen and sulfur content analysis will be taken allcust once per 

week when utlcust one coal fired hoilcr is in operation. The sample must be taken 

J()llowing ASTM tvfcthod D2234/D22J4M-07. 

9.3. Coal nitrogen and sulfur content will be determine<.! using ASTM Method DJ 176-Sl) (us 

rc<1pprovcd in 2002). Note, other ASTM methods related to sample collection and 

preparation may need to be followed in order to pcrlonn this test.

9.4. As an alternate to coal nitrogen ami sulfur content testing at the plant, certified results of 

testing by the coal mine operator of coal actually sent to the Centralia Power Plant may 

be used. Testing fn:quency should be no less frequent than required above. 

Reporting l{cquircmcnts

and 4 must be submitted to the Washington State Governor, Ecology, and SWCAi\ within :10 

days of achieving the milestone.

minimum, be documented in writing and submitted to S WCAA and Ecology with the 

emissions monitoring data per Condition 12. Additional rccordkecping and noli fications 

related to excess emissions may also be required by SWCAA or Ecology regulation. Excess 

emissions that TrunsAltu believes arc unavoidable must be dol:umentcd as required in WAC 

173-400-107 (or section I 09 alter that section is approved into the Washington SIP) and 

SWC;\1\'s unavoidable excess emissions requirements. 

12. Emission monitoring data will be reported to Ecology and to the S WCAA. 

12.1. Continuous emission monitoring reports \Viii be submitted within 30 days allcr the end 

of each calendar qumicr. The reports must contain the following information:
