March 31,2011FullCompliance EvaluationCompleted:April 1,2011 Purpose The above listed certificates of operation for Tennessee Valley Authority (TVA)are due to expire on July 17,2012.An annual inspection of the equipment that is covered by the certificates was made at Sequoyah Nuclear Plant on March 31,2011.The observations that were made during the inspection are summarized in this report.This report also includes discussions of the operation of the permitted equipment, the air pollutant emissions, and the applicable regulations.
Process Description TVA Sequoyah uses two nuclear reactors, which are referredtoas Reactor Units#1and#2,toheat pressurizedwater.Foreachreactorunit,thispressurizedwater,whichcirculatesinaclosedloop,isusedasasource ofheattoproducesteaminside of four parallelsteamgenerators.
The resulting steamfromthefoursteam generators ofeachunitissenttoa commonheaderand is then usedina high-pressure turbine followed by three low-pressure turbines in series to power a generator that produces electricity.
The steam is condensed after it exitsthefour turbines, andthewater,whetherintheliquidorgaseous(steam)state,circulatesinaclosedloopforeachunit.Thiswateris circulatedbytwo parallelfeedwaterpumpsthatareeachdrivenbyaturbine.These two turbines for eachunitare powered by"extraction"steamthatis divertedfromtheinitial high-pressure turbine.Water from the adjacent Tennessee Riverisusedto condense the steam.Reintroduction of this waterintothe river cannot resultinthe downstream temperature of the river being raised by more than 5.4°F during the months of April through Octoberand9.0°F during the months of November through March as averagedovera 24-hourperiod.The temperature ofthewaterthat is dischargedintothe river also cannotfluctuatebymorethan3.6°F duringanyhour.Holding ponds are sometimes sufficienttocoolthe watertothe desired temperature.
However,itisoften necessarytocool this water further in either of two cooling towers, which are designatedastheUnit#1 cooling tower (Certificate
-01C)andtheUnit#2 cooling tower (Certificate
-03C).In addition, reintroduction of the water into the river cannot result in the downstream river temperature exceeding an average of 86.9°Fovera 24-hour period unless the water is being cooledinone cooling tower per operating reactor unit.Water mist that is emittedfromthetwo cooling towers contains entrained particulatematter.These particulate emissions are uncontrolled and originatefromdirt,silt,etc.intheriverwater.
For each ofthetwo reactor units, the initial high-pressure turbineandthetwo feedwater pump turbines are each supplied with lubricatingoilbyanoil recirculationsystem.In addition, the electricity generator ofeachunitis suppliedwithsealoilbyanoil recirculationsystem.Each oftheseeight recirculation systems includesanoil reservoirthatis equippedwithanoil vapor extractor.
The extractors serve to vent oil vaporfromtheairspace abovetheoil reservoirs.
Each of the eight oil vapor extractorsalsoservestoremove waterfromtheoilthatresultsfrom inadvertent contact betweentheoilandsteam.
Hydrogengasis used to cool the bearings of the two electricity generators,andtheoil vapor extractorforthesealoil reservoir of each generatoralsoservesto remove dissolved hydrogenfromtheoil.
Hydrogenisnot consideredtobeanair pollutant.
Particulate emissions ofoilmist, whichisa VOC, result from each of the eight oil vapor extractors.Theoil mist emissionsfromthe extractorfortheoil reservoir of the initial high-pressure turbine of each unit are controlledbya demister,andtheoil mist emissions from the othersixoil vapor extractors are uncontrolled.
Oil vapor extractors for coal-fired steam generating facilities are classified as insignificant activities in accordance with§8(a)(l)a.
However, because such extractors for nuclear-powered steam generating facilitiesarenot specifically listed as insignificantactivities,TVAhasbeen informed that installationpermitsand initial certificates of operationwillbe issuedfortheUnit#1and Unit#2oil vapor extractors.

Each ofthetwo cooling towerswasusedfor814hoursduring calendaryear2009.The estimated particulate emissionsfromeach ofthesetowersaregiveninTableIattheend of thissection.The potential emissionsarebasedon continuous operation.
Installation of the Unit#1and#2coolingtowerswas completedin1980.The particulate emissionsfromeach ofthetwo cooling towers are limitedbyRule10.3 (Schedule2)to115.2 lbs/hr, basedona process weight of139,690tons/hr.This limitationismore stringentthantheRule10.7particulate emission limit of 0.25 gr/scf(85,760lbs/hr)foreachtower.However,amorestringentparticulateemissionlimitation of7.2lbs/hrhasbeenpreviouslyestablishedforeachtowerbecauseithasbeendeterminedthatoperationattheRule10.3allowableemissionratewouldresultinthe creation of a particulate non-attainment area.TennesseeValleyAuthority-SequoyahNuclearPlantPage4 4150-30700804-06C Insulation Saws A and BInsulationSawAwasnotinoperationatthetime oftheinspection,andInsulationSawBisnotcurrentlyinuse.SawAanditstwoprefilters,twoHEPAfilters,twosettlingdrums,andtwobagfiltersandSawBanditsthreeprefiltersandthreeHEPAfiltersappearedtobeingoodcondition.ThetwosettlingdrumsandtwobagfiltersforusewithSawBwerenotinposition, and theywillbe replaced before the sawisusedagain.SawAisusedforanaverage of4hrs/day,5days/wk,and6wks/yr.SawBwaslastoperatednolaterthanin2003.EachHEPAfilterhasanestimatedparticulatecontrol efficiency of99.9%.Eachsettlingdrumandbagfilterinseriesisestimatedtobe94%efficientin controlling particulate emissions.Theestimatedparticulateemissionsfromeach ofthetwosawsaregiveninTableI.Theseemissionsareconservativelybasedoncontrolonlybyasettlingdrumfollowedbyabagfilter.Thepotentialemissionsarebasedoncontinuousoperation.InsulationSawAwasinstalledin1989.TheparticulateemissionsfromthissawarelimitedbyRule10.3(Schedule2)to0.49lb/hr,basedonaprocessweight of80lbs/hr.Inaddition,theparticulateemissionsfromeach oftheexhaustpoints ofthissawarelimitedbyRule10.7to0.25gr/scf.Thislimitationisequivalentto0.39lb/hrforeach ofthetwobagfilters.
This limitation cannot be converted into units of lbs/hr for the set of HEPA filters because the exhaustflowrate throughthefiltersisnotavailableatthistime.
Insulation Saw B was installed in about 1988.However, as of 2005, Insulation Saw Bwentfortwoyearswithoutbeingoperated,anditwasnolongerconsideredtobeanexisting source at that time, in accordance with§8(c)(l).Potential particulate emissions from Saw B,beforebeingcontrolled,are estimatedtobe9.7tons/yr.Therefore,theparticulateemissionsfromthissaware subjecttoRule27.3.Control of these emissionsbyasettlingdrumfollowedbyabagfilterhasbeen determinedtobereasonableandproper,in accordancewithRule27.3.Anappropriate reasonableandproperlimitationfortheparticulateemissionsfromSawBhas been previously determinedtobe0.20lb/hr.ThislimitationismorestringentthanboththeRule 10.3 (Schedule 2)particulate emission limit of0.49lb/hr,basedona process weight of80lbs/hr,andtheRule10.7 particulate emission limit of0.25gr/scf,whichis equivalentto0.39lb/hrfor each ofthetwobagfilters ofthissaw.TheRule10.7limit cannot be convertedintounits of lbs/hrfortheset of HEPA filters ofthissaw because the exhaustflowrate throughthefiltersis not available at this time.4150-10200501-08C Auxiliary BoilersAandB AuxiliaryBoilersAandBarenotcurrentlyinuse.Thesetwoboilers appearedtobeingoodcondition.Therequiredcertifications ofdieselfuelsulfurcontentandtherequiredlogs ofdailyhours ofoperationandmonthlydieselfuelusageforeachboilerwerebeingmaintained.TennesseeValleyAuthority-SequoyahNuclearPlant Page 5 Each ofthetwoboilershasaratedcapacity of54.5MMBtu/hr.Theyarenormallynotinuse.BoilerAwaslastoperatedbriefly(22minutes)fortestpurposesonSeptember 16,2004,andBoilerBwaslastoperatedonNovember14,2000.Theyarefueledexclusivelybydieselfuelthathasaverageandmaximumsulfurcontents of0.0015%and0.06%byweight, respectively.Theestimatedemissions of particulate (PM25,PMio,andtotal),NOx,SOx,CO,VOCs,methane,andC02(actualandC02e)thatresultfromdieselfuelcombustioninthetwoboilerscombinedaregiveninTableIIattheend of this section.TheseemissionswerecalculatedbyusingAP-42(1998)emission factors.Thepotentialemissionsarebasedon simultaneousoperationofthetwoboilersattheirrated capacitieswhileburningdieselfuelthathasthemaximumsulfurcontent.Thepotentialemissionsarealsobasedonthesum ofthetotalamountoftimethatBoilerAisin operationandthetotal amountoftimethatBoilerBisin operationbeingequalto2,000hrs/yr.47.0%and69.7%

Potential particulate emissionsfromeach ofBoilersAandBare estimatedtobe1.313 lbs/hrand5.7 tons/yr, based on continuous operation.
Therefore, the particulate emissions from these boilers are subjecttoRule27.3.An appropriate reasonable and proper limitation, in accordancewithRule27.3,forthe particulate emissionsfromeach of BoilersAandBhasbeen previously determinedtobe0.030 lb/MMBtu,whichis equivalentto1.64 lbs/hrforeachboilerwhileitis operatingatitsratedcapacity.Nocontrolsarenecessaryinordertoachievethis Tennessee Valley Authority-SequoyahNuclearPlantPage6 limitation for eitherboiler.This limitation is equivalenttothe particulate emissionlimitthat,althoughnotapplicabletothetwoboilers,isstipulatedby
§60.43c(e)(l) ofSubpartDc.This limitationismore stringentthantheRule8.2(Schedule2) particulate emission limit of 12.72 lbs/hr for each boiler.This limitationisalso more stringent than the Rule 26.6 (RACT)particulate emission limit of0.15864lb/MMBtu,which,althoughitisnotapplicabletothetwoboilers,is equivalentto8.65 lbs/hrforeach boilerwhileitis operatingatitsratedcapacity.AnappropriatesulfurcontentlimitationforthedieselfuelthatisburnedinBoilersAandBhasbeenpreviouslydeterminedtobe0.06%byweight.TVArequestedthislimitationinordertoqualifyasasyntheticminorsource.Combustion ofdieselfuelwiththemaximumallowablesulfurcontentineither boileratitsratedcapacityresultsinpotentialSOxemissions of 3.44 lbs/hr.This SOx emission rate is the effective SOx emission limitation for each boiler.ThislimitationismorestringentthantheRule13.2 SO2emissionlimit of4lbs/MMBtu,whichisequivalentto218.0lbs/hrforeach ofthetwoboilerswhiletheyareoperatingattheirrated capacities.TheVOCemissionsfromBoilersAandBaresubjecttoBACT(Rule25.3).IthasbeendeterminedthatnocontrolsarenecessaryinordertosatisfyBACTfortheseemissions,andnoquantitativeBACTVOCemissionlimitationsarenecessary.Nolimitationsareapplicablefor the emissions of CO, methane, and CO2 from either of the two boilers.4150-30703099-09C Carpenter Shop None of the equipment ofthecarpentershopwasinoperationatthetime of theinspection.Thetwo radial-armsaws,tablesaw,bandsaw,planer,twofloorvents,andbaghouse appearedtobein good condition.
The carpentershopis operated for approximately4hrs/day,5days/wk,and6wks/yr.
The baghousehasan estimated particulatecontrolefficiency of99%.The estimated particulate emissionsfromthis carpentershopare giveninTableI.The potential emissions are based on continuous operation.
The carpenter shop was installedinMay1995.The particulate emissionsfromthis carpentershopare limitedbyRule10.3(Schedule2)to1.42lbs/hr,basedonaprocessweight of450lbs/hr.This limitationismorestringentthantheRule10.7 particulate emission limit of 0.25 gr/scf (3.43 lbs/hr).4150-30900203-10C Abrasive Blasting OperationAbrasiveblastingwasnotbeingperformedatthetime oftheinspection.Theroomthatit is performedinandthefilterpanelappearedtobeingoodcondition.

Potential particulate emissionsfromeach of Emergency Generators 1A, IB,2A,and2B are estimatedtobe 2.676 lbs/hr.The particulate emissions from each of these generators are limitedbyRule10.2 (Schedule1)to4.07lbs/hr, basedona process weight for each generator of1,976lbs/hr(38.4 MMBtu/hr-s-0.137MMBtu/galx7.05lbs/gal).This limitationismorestringentthantheRule10.7 particulate emission limit of 0.25 gr/scf(18.75lbs/hr)foreach emergency generator.
Potential particulate emissionsfromeach of Blackout Generators1and2are estimated tobe1.289lbs/hrand0.31ton/yr,basedonoperationfor480hrs/yr(theRule2.7limitation).Therefore,theparticulateemissionsfromthesegeneratorsaresubjecttoRule27.3.Anappropriatereasonableandproperlimitation,inaccordancewithRule27.3,fortheparticulateemissionsfromeach ofBlackoutGenerators1and2hasbeenpreviouslydeterminedtobe1.80lbs/hr.Nocontrolsarenecessaryinordertoachievethislimitationforeithergenerator.ThislimitationismorestringentthanboththeRule10.3(Schedule2)particulateemissionlimit of Tennessee Valley Authority-SequoyahNuclearPlantPage9 2.27 lbs/hr, basedona process weight for each blackout generator of 952 lbs/hr (18.5 MMBtu/hr-0.137 MMBtu/galx7.05 lbs/gal),andtheRule10.7 particulate emission limit of 0.25 gr/scf (12.10 lbs/hr)for each blackout generator.
An appropriate limitationforthe sulfur content of the diesel fuel that is burnedinthesix generators has been previously determinedtobe 0.06%by weight.TVA requested this limitation in order to qualifyasa synthetic minor source.Combustion of diesel fuel with the maximum allowable sulfur contentinthesixgeneratorsattheirrated capacitiesresultsin potential SOx emissions of 2.422 lbs/hrforeach ofthefour emergency generatorsand1.17 lbs/hr for each ofthetwo blackout generators.TheseSOx emissionratesarethe effective SOx emission limitationsforthesix generators.
