### Although there are numbers in the application, I don't think it was driven by a $/ton or efficiency, in the end. At least nothing that would be helpful to you. Attached is the permit and response to comments. There is stuff about NOx in the comments Let me know if you want the whole file/application.

### Hello, Please direct this request to the appropriate person, as necessary. Thanks. I have two questions on information posted on the RACT/BACT/LAER Clearinghouse website concerning a BACT determination ADEQ made concerning the Southwest Electric Power Company, John W. Turk Jr. Power Plant, permit number 2123-AOP-RO, date 11/05/08. Mr. Rheaume is the listed contact. I would greatly appreciate a response in the next few days. Questions: 1. What did you determine to be the cost in dollars/ton of NOx removed for selective catalytic reduction (SCR)? 2. What did you determine to be the NOx removal efficiency for the SCR system? Please call me or email ifyou have questions. An email response will be appreciated. Thank you so much for your help.

### Here is the information you requested. Ifyou have any further questions please letus know.
1. Whatdid you determine to be the costin dollars/ton ofNOx removed for selective catalytic reduction (SCR)? No economic information was provided for NOx removal. Their last permit application addendum dated 3/31/2005 is EDMS Document ID: 32782742. The second paragraph ofPage 2 of5 states that no economic

. analysis was required for BACT control due to the fact that the most stringent control technology was

employed. 2. Whatdid you determine to be the NOx removal efficiency for the SCR system? Approximately 71 % using SCR

## + LNB. See Table at top ofPage 2 of5 on same EDMS document EDMS Document ID: 32782742.

- Not valid for construction or operation Main Boiler AECI
- Norborne is proposing to build a new supercritical pulverized coal fired (PCfired) boilerwith a steam turbine generator with a nominal (= 

### rated) net electrical output of 689 

### MW (780 

### MW gross output). The unit will provide base load electricity and is designed to operate continuously. Construction of the plant is scheduled to begin in the early part of 2008 

### with commercial operation starting in 2012. 

### Low sulfur sub-bituminous Powder River Basin (PRB) coal is the intended fuel. The fuel is pulverized to the consistency of talcum powder and pneumatically injected through the burners into the furnace. PC-boilers are of a watertube design, meaning that the heat from the combustion gases is used to heat water inside of tubes and convert it to steam. The unit will be a dry bottom unit; coals with high fusion temperatures are burned, resulting in dry ash. NOx emissions will be controlled by LNB, over-fire air (OFA) and SCR. Baghouses will be used for filterable PM10, acid gas and other inorganic HAP control; while DFGD using lime will limit S02 emissions. A combination of baghouses and DFGD will control total PM10 emissions. CO and VOC emissions will be controlled using good combustion practices. The following table provides a summary of the design parameters of the proposed boiler/generator. t M' B'I a e**eSI~ ~n**

- Not valid for construction or operation the primary flame zone. Although FGR may be considered as a potential control option, it is not typically installed on coal fired units due to the high hot particulate-laden flue gas with relatively high O2 

### concentrations. FGR on a coal-fired boiler is estimated to achieve a NOx 

### reduction efficiency of less than 20%, due to a relatively low contribution of thermal NOx 

### to total NOx 

### formation. It is considered less**~ffective** 

### than the alternative post-combustion NOx 

### control options (E.g., SCR and SNCR) and therefore will not be examined further.

• Reburning In reburning, up to 25% of the total fuel heat input is provided by injecting a secondary (or reburning) fuel above the main combustion zone to produce a slightly fuel-rich zone with a stoichiometry of about 90% theoretical air. Combustion of reburning fuel at fuelrich conditions result in hydrocarbon fragments, which react with a portion of incoming NOx 

### to form hydrogen cyanide, isocyanic acid, and other nitrogen-containing species. These species are ultimately reduced to nitrogen. Finally, completion air is added above the reburn zone to complete burnout of reburning fuel. It is estimated that a reburn technology could provide a 50% NOx 

### reduction in emissions.

• Selective Non-Catalytic Reduction (SNCR) SNCR involves the direct injection of ammonia or urea at high flue gas temperatures (approximately 1600 OF
- 1900 OF). The ammonia or urea reacts with NOx 

### in'the flue gas to produce N2 

### and water. Although an SNCR system has been used as a retrofit, SNCR systems have not been applied to large new pulverized coat (PC) units. PC**~"~"~,~~,~,~"~~-- ~.eeUeFsi3r-eseAt~se-ver-aj~eesf§fli3roelems-~tlTat-mak-e~it~cl-i#iel:lIH<:reflstlf-e4l1at4:he~r-ea§eflt-···~~~·~~~~_**

### will be injected at the'optimum flue gas temperature, and thatthere will be adequate mixing and residence time. Because of the difficulties associated with applying SNCR to a large PC boiler, it is estimated that an SNCR system could provide a 30% NOx 

### reduction in emissions.

• Selective Catalytic Reduction The SCR system involves injecting ammonia into the boiier flue gas in the presence of a catalyst to reduce NOx 

### to nitrogen and water. The performance of an SCR system is influenced by several factors including flue gas temperature, SCR inlet NOx 

### level, the catalyst surface area, volume and age of the catalyst, and the amount of ammonia slip that is acceptable. The SCR system has been demonstrated on several large PC boilers on a continuous basis and many boilers have been retrofitted with SCRs to control NOx 

### emissions during ozone season. The SCR system is estimated to achieve an additional 50Ofcdo 90% reduction.

• Rotating opposed fired air (ROFA) and Rotamix® Rotating opposed fired air (ROFA) is a boosted overfire air system that includes a patented rotation process. Like typical OFA systems, ROFA stages the primary combustion zone to burn overall rich, with excess air added higher in the furnace to burnout products of incomplete combustion. The ROFA nozzles are designed to increase turbulence within the furnace, enabling the furnace volume to be used more effectively for the combustion process, and reduce the maximum temperatures of the combustion zone. A ROFA system was installed on an existing 80-MW (gross) bituminous-fired utility boiler in the summer of 2002. Test results showed that the

Through review of available technical publications and information as well as recently permitted and proposed limits contained in the RBLC and EPA's Modified Coal-Fired Utility Summary Spreadsheet, SCR with LNBs and OFA has been identified as the most commonly applied and effective technology for the control of NOx

### With regards to continuously operated Powder River Basin (PRB) coal-fired pulverized coal (PC) units, SCR is a relatively new control technology, and there are limited operating data available to evaluate long-term effectiveness of SCRs. Kansas City Power 

## & Lights' (KCPL's) Hawthorne Unit 5 ("Hawthorne") is the only new (not retrofitted) 'PRB coal-fired boiler currently operating in the U.S. which uses SCR technology. The Hawthorne unit had 

## a permitted limit at 0.12 Ib/MMBTU on a 30-day rolling average for the first 36 months following initial startup and a permitted limit of 0.08 Ib/mmBTU on a 30-day basis after the 36-month evaluation period. Hawthorne began operation around May 2001. AECI evaluated Hawthorne's performance for a period between July 1,2004 through March 31,2005 using the Clean Air Market database and determined that Hawthorn Unit 5 has achieved 0.079 Ib/MMBTU on a 30- day rolling average with 95% confidence (95% confidence equates to 2 standard deviations). In addition to the Hawthorne unit, W.A. Parish Generating Station in Houston, Texas also operates year-round subbituminous-fired PC units, Units 5 and 6. These units have been retrofitted with SCRs and LNBs with OFA. The SCR systems for Units 5 and 6 went into service in April 2003 and January 2003, respectively. Based on data evaluated by AECI for the period between June 1,2003 and June 30,2005, Parish Units 5 and 6 have consistently achieved a 30-day rolling average ofC.05 and 0.057 Ib/MMBTU (with 95% confidence), respectively.

### Based on the above research and analysis along with further evaluation by the Air Pollution Control Program during the Public Comment phase, the Air Pollution Control Program contends that the top level of control for operation of a PRB coal-fired boiler with LNB/OFA and SCR controls is 0.05 Ib/MMBTU on an annual basis. There are no other boilers either permitted or proposed with a lower limit than 0.05 Ib/MMBTU on an annual basis. In addition to the annual limit, a 3D-day rolling average is also included. The 3D-day rolling average was 0.07 Ib/MMBtu in the draft permit, but has been lowered to 0.065Ib/MMBtu. The addition of a 3D-day limit gives the facility flexibility in day to day operation and allows for small upset conditions as well as a small upswing toward the end of catalyst life where they may have some room to plan and allow for the least environmental unfavorable impact due to end of catalyst conditions. It also ensures that emission rates on a shorter time basis remain at a low, consistent level.**-~~-~"~""~."**

### Pollution Control Program is proposing both a 0.065 Ib/MMBTU 3D-day and an 0.05 Ib/MMBTU 12-month limits, the number of exceedances of a 0.65 Ib/MMBTU limit on a 24-hour basis is significantly limited by the annual limits and therefore a limit on a 24- hour basis is not included. The 3D-day and 12-month rolling averages are exclusive of startup and shutdown. In order to address the NOx 

### emissions emitted during these times of operation, AECI has proposed a 1,535 ton cap of NOx 

### per year. This is based on an emission rate of 0.051 Ib/MMBTU and a heat input rate of 6,872 mmBtu per hour. Lastly, AECI expects that the LNB/OFA controls will reduce the NOx 

### concentration in the flue gas to 250 ppmvd 

### @ 3% O2 

### which is equivalent to 0.35Ib/MMBTU (on a 3D-day rolling average basis) under all normal operating conditions on an on-going long-term basis, including low-load operations. Under optimal operating conditions, the LNB/OFA is expected to be operated at 140 ppmvd

- Not valid for construction or operation demonstrated on a long-term continuous basis. AECI conducted an economic evaluation of NOx 

### emission limits ranging from 0.0535 to 0.09 Ib/MMBTU (on a 3D-day rolling average). However, as per the draft of NSR Workshop manual, in the absence of unusual circumstance, the presumption is that sources within the same category are similar in nature, and that cost and other impacts that have been borne by one source of a given source category may be borne by another source of the same source category." Since AECI has not provided any data which differentiates this project from previously permitted units which have limits of 0.05 Ib/MMBTU on an annual basis, it is presumed that the costs these systems will incur can also be incurred by AECI. Therefore, the economic analysis provided by AECI was not considered in selecting the NOx 

### limit. Based on the performance data from other plants and NOx 

### BACT limits from other proposed and permitted units, the Department of Natural Resources proposes a BACT limit for NOx 

### emissions of 0.05 Ib/MMBTU on 12-month rolling average exclusive of startup and shutdown. A shorter term BACT limit of 0.065 Ib/MMBtu is also beir:l9 proposed on a 3D-day rolling average (also exclusive of startup and shutdown). This higher number for the 3D-day rolling average is viewed as acceptable such that it allows for shorter term variability, especially at end of catalyst life conditions. This level of control equals the lowest recently permitted facilities and has been demonstrated on at least two other PC boilers firing PRB coal.
