Gentlemen: November 14, 2008

Mr. David Hearne Ohio EPA- Agency 13 (Cuyahoga) Cleveland Division ofAir Quality 1300 E. 9th Street Cleveland, OH 44114

In accordance with the requirements contained in OAC 3745-110,theNortheast Ohio Regional SewerDistrict conducted a NOx RACT Study for two mid-sizedpackage boilers (sources B002 and B003) located at its Southerly WastewaterTreatment Center. The study was conducted to determine whether ornot there are any technically feasible and cost-effective techniques for reducing NOxemissions from the two package boilers to meetthe newNOxRACT limit of0.10 lbs (NOx)/mmBTU input. The only technically feasible technique was the replacement ofthe existing low NOx burners with new ultra lowNOxburners. Quotations were obtained from three""'

## vendorsa~d the

## ann~~raveragec~st:effectiveness ofinstalling new ultra low NOx burners has been estimated to be $51,744/ton ofNOxreduced. Thecost-effectiveness ranges from a low of$39,831/ton ofNOxreduced to a high of$72,898/tonofNOx reduced. As a result, theNEORSD respectfully requests thatthe existing NOx limit for ! 

## sources B002 and B003 of0.15 lbs/mmBTU be retained. 

# '" It

## should also be noted thatthe Southerly WWTC has four multiple hearth incinerators in which biosolids (sewage sludge) is burned. TheNEORSD is getting ready to replace the multiple hearth incinerators with new fluidized bed incinerators.

## In February 2008, Ohio EPA personnel informedthe City ofCleveland Division ofAir Quality (CDAQ) that Southerly's new fluidized bed incinerators would be subject toNOxRACT requirements. In a letter dated February 25, 2008 (copy attached), we explained the reasons why the new fluidized bed incinerators should notbe subjectto NOxRACTrequirements. On AprillO, 2008, SarahRehner (CDAQ) informedmethatboth Ohio EPA and CDAQ personnel agree that Southerly's new fluidized bed incinerators are not subjectto NOx RACT requirements, due to the reasons contained in the attached letter. In addition, Ohio EPA and CDAQpersonnel also agreedthat Southerly's existing multiplehearth incinerators are not subjectto NOxRACT requirements since they are being replaced with new fluidized bedincinerators.
Please do not hesitate to contact me at 216-881-6600 ext. 6405 ifyou have any questions orrequire additional information.

When boiler No. B003 was placed into service in the early 1990s, it was equippedwith a lowNOxburnerto meet a permit limit of0.15 lbs/mmBTU input. Atthe same time a new lowNOx burner was installed in boilerNo. B002. Currentdiscussions with a number ofburner manufacturers indicated that burnertechnology has progressed to apointthatwe can meet the 0.1 lbs/mmBTU input limit by retrofittingthe existing boilers with new ultra low NOxburners. Below are calculations to determine the NOxreduction from both boilers in the event that new ultra lowNOx burners are installed in B002 and B003.

## Combustion control techniques reduce the amount ofNOxemission by limitingthe amount ofNOx formation duringthe combustionprocess. This is typically accomplished by lowering flame temperatures. Combustion control techniques are generally more economical thanpost combustion methods and have been used to for NOx emissionreduction in new and existing boilers with heat capacities less than 100 mmBtu/hr. Thecontrol techniques most frequently applied include burner modifications and flue gas recirculation.



## 5

## 1. Burner Modifications 

## Burner modifications for NOx control involve changing the design ofa standard burner in orderto create a larger flame. Enlarging the flame results in lower flame temperatures and lowerthermal NOx formation which, in tum, results in lower overall NOxemissions. Thetechnology canbe applied to most boiler types and sizes. Nearly all burner modifications or lowNOxburners use some method ofstaged air or staged fuel technique.

· Staged combustion burners achieve lowerNOxemissions by staging the injection

ofeither air or fuel inthe near burner region. The division ofcombustion air reduces the oxygen concentration inthe primary burner combustion zone, lowering the amount ofNOx formed**~;~nd** 

## increased the amount ofNOxreducing agents. Secondary and tertiary air completes the combustion downstream ofthe primary zone, lowering the peaktemperature and reducing thermal NOx formation. SinceNOx is highly dependent on peak flame temperature, this is an effective methodto moderate thermal NOx reductions. However, given thatthe existingburners are almost 20-years old, modification ofthe burners is not recommended. As a result, this option has been eliminated from further consideration. 2. Flue Gas Recirculation 

## Flue gas recirculation involves recycling a portion ofthe combustion gases / 

## ,.,c,e.c from the stacktothe boilerwindbox. Introducing some ofthe flue gas back into 

# IJ. the combustion airreduces peak flame temperatures. The incoming air is diluted 

## .1\f,./.**:}a~** , 

## and the oxygen concentration in the combustion zone is reduced. During 

## J.>csi,&lc. 

# d"c combustion, the recirculated flue gases also absorb some ofthe heat andthereby 

# +,, 

# rc**-l'l~·f.;+** reduce thepeak combustion temperatures. Substantial modifications are required "' to retrofit a boiler with flue gas recirculation and room to install the additional equipment, gas recirculation fan, dampers and ducting is not available. As a result, this option has been eliminated from further consideration

c. Post-Combustion Techniques 

## Post combustion control methods include Selective Non-Catalytic Reduction (SNCR) and Selective Catalytic Reduction (SCR).

6

## 1. 

## Selective Non-Catalytic Reduction Selective non-catalytic reduction involves the injection ofaNOx reducing agent, such as ammonia orurea, into the boiler exhaust gases at a temperature ofapproximately 1400- 1600°F. The ammonia or ureabreaks downtheNOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction can reduce NOxemissions up to 70%. However, the technology is extremely difficultto applyto industrial boilers that modulate or cycle frequently, since the ammonia (or urea) must be injected in the flue gases at a specific flue gas temperature. Inboilers (like Southerly's) that modulate or cycle frequently, the location ofthe exhaust gases at the specified temperature is constantly changing. Thus, it is notfeasible to apply selective non-catalytic reduction to industrial boilers thathave high turndown capabilities and modulate or cycle frequently. Accordingly, SNCRis not considered a technically feasible option for NOxemission reduction and has been dropped from further consideration. 

## 2. Selective Catalytic Reduction Selective Catalytic Reduction involves the injection ofammonia in the boiler exhaust gases in thepresence ofa catalyst. The catalyst allows the ammoniato reduce NOx levels at lower exhausttemperatures than selective non-catalytic reduction. Unlike selective non-catalytic reduction, where the exhaust gases -· must be approximately 1400-1600°F, SCRcan be utilized where exhaust gasses are between 400°F and 1200°F, depending on the catalyst used. SCR can result in NOxreductions ofup to 90%. However, it is_s_ost!Y to use and canrarely be costjustifiedon boilers with inputs less than 100 MMBtu/hr. As a result, this option has also been dropped from further consideration. 

## d. Other Options Investigated 1. 

## Close coupled or separated over-fire ports- NotApplicable 2. Burners out ofservice

### Typical Burner Installation Procedure Ref. : BR-9001 R1 Burner General arrangement Drawing. 

### 1. 

### Refractory throat. Natcom burnerthroat should b·e fabricated using a refractory material that can accommodate high temperatures and very low shrinkage when cured. Plastic poundable or castable refractory with 80% alumina content is recommended. The throat must be cylindrical in shape with the ID ofthe refractory material equal to the ID of the burner stainless steel throat liner. A qualified, experienced tradesman should perform the refractor work. He should determine: Procedure for installing the refractory. Type of refractory best suited for the application. Location and type ofanchors to be used. Need and location of Expansionjoints if necessary. Curing schedule and procedure. 2. 

### Positioning of burnercomponents: The geometry (positioning) ofthe burner components significantly influence the burner performance. Consequently it is important to locate the burner components correctly with respect tothe boilerfront wall. Please refer to the pertinent drawings for your burner in the instruction manual. Dimension 

### "A" locates: Flame stabilizer Oil Atomizer Guide pipe end Gas stabilizer injector. Dimension "B" locates: Primary gas injectors. Staged gas injectors. Mixed Gas injectors. Dimension "C" locates: Hyper-Mix impulse lance. Windbox is located per burner horizontal centerline axis. Front of Windbox must be perpendicular to the burner central axis. Circular opening at front ofwindbox must be centered about the boiler front wall opening. Frontface ofthe windbox must be parallel to the boiler front wall. 

## 3. WELDING: Burnerthroat flange (Material SS304L) must be welded to the boiler front wall. Use ER309Lwelding rod. Burnerthroat (material SS304L) weld to burnerthroat flange after positioning per dimension A in section 2 above. Use welding rod ER308L or ER309L. Windbox (material G44.21-44W) to be seal welded to boiler front wall after having been positioned onto boiler front wall. Use E7018 welding rod. Hyper-Mix ring (material G44.21-44W, ASTM A36) to be tack welded to the burner throat using the guide tabs on the ring. Use ER309L welding rod. NB. To facilitate transportation some components are temporarily positioned and fastened using bracesthat are painted fluorescent green. These braces should be removed prior to installation.

## Street- Fourtb Floor · Cleveland, Ohio 44115 Re: Southerly Wastewater Treatment CenterFebruary 25, 2008

NOx RACT Applicability -NewFluidized BedIncinerators DearMs. Rehner: Thankyou very muchfor takingthetime lastweekto discusswithmethe reasons whythe City ofClevelandDivision ofAir Quality (CDAQ) and OhioEPAfeel thatthe NOxRACTRules (OAC 3745-110) apply to Southerly's new fluidized bedincinerators. The Northeast Ohio Regional SewerDistrict(NEORSD) agrees thatNOxRACT appliesto Southerly's four existing multiplehearth incinerators (MHis). As a result, we planto submit a NOx RACT Study for the existingMHis, unless OhioEPA approves a determination thatthe study is not necessary for incinerators (like Southerly'sMHis) that are beingreplaced. On the otherhand, after again reviewingthe terms and conditions contained in OAC 3745-110, we firmly believethatNOxRACT does not applyto Southerly's new fluidized bedincinerators forthe following reasons: 1. NOxRACTdoes not apply to modified sources that are notboilers, engines orturbines. Therule establishes two criteria for a new ormodified source at OAC rule 3745-110-02(A) (2): (a) The source, as defined in rule 3745-110-01 oftheAdministrative Code, is a very large boiler, large boiler, mid-sizeboiler, small boiler, stationary combustion turbine, or stationary internalcombustion engine; and

## (b) 

## Exceptwhere the emission limitations andrequirements ofan applicable new sourceperformance standard under 40CFRPart 60 are more stringentthanthe emission limitations andrequirements ofthis chapter, any new or modified source issued a permit-to-install after January 1, 2008, shall comply with the requirements ofthis chapter. Sincetherule uses the term "and" both ofthese criteria mustbe satisfied for the ruleto be applicable. Thatis, "any new or modified source" in (b) is necessarilylimitedbyhow a "source" is defined in (a). Therefore, modified sources, likethe Southerly incineratorreplacementproject,that are notboilers, engines orturbines should notbe subjecttoNOxRACT. 2. This does notmean thatnewandmodified sourceswillbe installed withouttechnically feasible and economicallyreasonableNOxcontrols. The same criteriathat are used to determineNOxRACTunder Section 110 shouldbe applied inthe PTIprocess to deterininetheBestAvailable Technology (BAT) for NOxreduction. NEORSD is proposing lowNOx burnertechnology for the fluidized bed incinerators, which is reflected in the proposedNOxrate in ourPTI application. 3. To interpret subsection2(b) ofthe NOxRACTrule as applying to any new ormodified sourcecould not havebeenthe intentoftherule since: (a) NOxRACT studies are only necessary for existing sources that are not conducting a BATanalysis associated with a PTIprocess. Requiring a NOxRACT study with certified engineers, in addition to a BAT analysis, is redundant. (b)NOxRACT studies require data from existing source operations (maximum annualproduction rates, maximum daily and annual NOx emission rates, documentation ofexisting control efficiency and any testing performed) that are not available from new sources or modified configurations. These studies were not intended for newsources. (c) NOxRACT studies require a schedule for retrofittingthe units. New and modified sources are required to implementNOxcontrols upon startup.

## (d) Aswe interprettheNOxRACTapplicability, onlythe new and modified boilers, engines andturbines thathave numericNOxRACT limits in the rule arerequiredtocomplywith the NOxRACTrule. These numeric standards are easily incorporatedinto the PTI along with

## the various recordkeeping andreportingrequirements. Other sources achieveNOx controls by employing BAT.
