Version 2July 28, 2010Frequently Asked Questions - TechnicalP. 1 of 19Question # Question ResponseQ A1-6 The coal-fired power plant has recently been retired andreplaced with new gas turbines and a new combined cycleplant. Should we answer "yes" to this question?Although the coal-fired generating units have been retired, answer“no” to Question A1-6, because the plant has not been retired.Q A1-8 We are currently in the process of making conversions tothe plant and have no intention to use fossil fuel in thefuture. However, we used coal in 2009. Should I continueto fill out the questionnaire or should I stop after thecompletion of this question?Although the plant has no intention of using fossil fuels in the future,the plant used coal as a fuel source in 2009; therefore, you shouldcontinue to fill out the questionnaire on the operations of the plant in2009. Please complete as much of the questionnaire as possible forthe time in 2009 that the plant used fossil fuels, and add a commentto Part A to elaborate on your current operations.A1-8 If the plant uses a little natural gas, but primarily uses blastfurnace gas, what should they report?They should select "gas" and add a comment in the comments pagefor the use of blast furnace gas.A1-8 If the plant is a coal-fired plant, but oil is used for start-upand stabilization, should I mark oil in Question A1-8?Fuels only used for start up or in emergency generators should not bereported in Question A1-8. If the plant uses a secondary fuel forother purposes (including stabilization that is not associated withstart-up activities), mark that fuel in Question A1-8.A1-10 If the facility only has one NAICS code, what do we putunder secondary and tertiary codes?If the facility only has one NAICS code, you may leave the answerblank for the secondary and tertiary codes.A1-10 How can a facility identify their NAICS code? Information about NAICS codes can be found atwww.census.gov/eos/www/naics/.A2-1 For Question A2-1 should the plant name (as listed in EIAForm 860, Schedule 2, Line 1) be provided or should theEIA Code number (listed in EIA Form 860 above Line 1)be provided?Provide the EIA Plant Identification Code, not the plant name.Section 2.2 If the facility did not discharge any flow through itsoutfalls in 2009, what do we enter for flow?Please enter "0" (zero) in the flow answer cells.Part AVersion 2July 28, 2010Frequently Asked Questions - TechnicalP. 2 of 19Question # Question ResponseSection 2.2 How should this section be completed if the facility has noNPDES permitted outfalls?Do not complete Part A, Section 2.2 if there are no NPDES permittedoutfalls and state in the comments section that there are no outfalls.However, if the plant has emergency outfalls present and permitted,such as an emergency outfall for a surface impoundment, you mustcomplete Part A, Section 2.2.Section 2.2 If one of the outfalls at the facility is a storm sewer inletand the plant does not measure the flow rate, how shouldthe plant answer Section 2.2?The plant should estimate this flow and report it in Section 2.2. Youmay reference design flow calculations that were completed when theplant storm sewer piping was designed, or you may use the numberof days of discharge in 2009 with an estimate of the average stormevent to estimate the stormwater flow. If the plant does not keepthese records, you can estimate flow by using precipitation data froma local rain gauge (available through USGS) and performing runoffcalculations based on the contributing area of the plant. One methodthat can be used to calculate runoff is the NRCS Curve NumberMethod; however, you may choose the method that is mostappropriate for your plant. Report all estimations used in theComments section.A2-4 If the facility has an industrial discharge permit through aPublicly Owned Treatment Works (POTW) does thiscount as a NPDES permit?No, this permit is not a NPDES permit and does not require reportingin Question A2-4 (Table A-2) or Section 2.2. However, questionsthroughout the survey may require the destination of a waste streamto be noted and, where appropriate, the plant should select "Indirectdischarge to a publicly or privately owned treatment works" (see, forexample, Question A9-6).Version 2July 28, 2010Frequently Asked Questions - TechnicalP. 3 of 19Question # Question ResponseA2-5, A3-2,and A4-2Do nuclear facilities still need to providelatitude/longitude for discharges, pond/impoundments,and landfills? There is concern that this information needsto be kept safe from disclosure.An exception will not be provided for these questions. All plants arerequired to provide latitude/longitude for all discharges,ponds/impoundments, and landfills located at the plant. If disclosureof this information is a high concern for nuclear plants, they shouldclaim their response as CBI.A2-10 For emergency outfalls on stormwater ponds, what shouldbe used for the percentages in Table A-3 if there was noactual discharge in 2009?Base the percentages on the relative contributions of wastewaters inthe pond (e.g., for stormwater ponds, enter 100% stormwater). Entercomments to describe the specific situation if necessary.Section 3 Should sedimentation ponds be reported? If the sedimentation ponds contain process wastewater, thensedimentation ponds should be reported. Note: contaminatedstormwater is considered to be process wastewater.A3-2 How should a pond be reported in Table A-4 if it wastaken out of service, lined, and brought back into serviceat a later date considering the pond had the samefootprint? Additionally, how should a pond be reported ifit was taken out of service, split into two impoundments(same total footprint), lined, and brought back into serviceat a later date?Identify each pond to be entered into Table A-4 based on the plant'scurrent configuration. For the first example, report the pond as linedand enter the year initially brought on line as the year the initialunlined pond was put into service. For the second example, reportthe two individual lined ponds and enter the year initially brought online as the year the original unlined pond was put into service. Add acomment for both ponds to say they were originally one pond.A3-2 Does a cooling water pond need to be reported? All ponds containing process wastewater (including including oncethrough cooling water and cooling tower blowdown) need to beincluded in Tables A-4 and A-5. However, cooling water ponds donot need to be reported in any of the tables in Part D.A3-2 How should a plant report latitude and longitude for apond that has no discharge outlets including no emergencyoutlets?The plant should provide the latitude and longitude of the pond itself(e.g., center point) and state in the comments section that the pondhas no outlets and the coordinates provided are for the pond itself.Version 2July 28, 2010Frequently Asked Questions - TechnicalP. 4 of 19Question # Question ResponseA3-2 Because the units requested are feet, how specific does thereported distance between the pond and the nearest surfacewater need to be? For example, if the plant only knowsthis distance is around 10 miles, what should be reported?The plant should report the distance by multiplying the distance inmiles by 5,280 feet.A3-2 Should a thermal mitigation pond only used to cool plantprocess wastewater prior to discharge be included in PartA Section 3?Yes, all pond/impoundment units should be reported in Table A-4, inPart A Section 3.A4-2 I store bottom ash and coal pile runoff sludge on a linedcoal pile storage pad. Should I identify this as a landfill inTable A-6.For the purpose of this questionnaire, the coal pile storage pad shouldnot be identified as a landfill in Table A-6.A4-3 If boiler blowdown is used to moisten fly ash beforesending it to the landfill, what should be included as wastestored or disposed of in the landfill?You should check both the "fly ash" and "other" boxes. Enter "boilerblowdown" in the "other, specify" field.A5-2 A5-2 requests that an “aerial map” be provided. Not surewhat an “aerial map” is; would you be referring to a UStopographic map? Or are you asking for an “aerialphotograph”?In Question A5-2, EPA is looking for an aerial depiction of the sitethat shows the property boundary of the plant site and relative layoutof buildings, ponds/impoundments, landfills, and other significantfeatures of the plant. You may submit an aerial photograph,supplemented with notes as necessary, or a topographic map, as longas the requested information is shown.A5-3 EPA requires flow rates to be reported in gpm or gpd. Canflows instead be provided in other units, such as mgd?Flow rates will have to be provided in gpm or gpd, as specified bythe specific questions in the questionnaire.Version 2July 28, 2010Frequently Asked Questions - TechnicalP. 5 of 19Question # Question ResponseA5-3 What if my plant only tracks total plant flows and does notkeep track of any internal flows necessary to complete thediagram for Part A?The plant should provide their best estimates of all internal flowsrequired for the diagram. Some flows can be determined usingestimates that involve tank volume and frequency of discharge. Anyestimation methods used should be explained in the Commentssection.A6-1 How should IDs for electrical generators be assigned whenyou have multiple boilers that can feed generators in anyconfiguration?Question A6-1 (Table A-8) should be completed on the generatorbasis. To complete question A8-1 (Table A-11) determine thecombination of fuels (from multiple boilers) that supplied thatgenerator with steam.A6-1 Does the total electric generation per unit in Part ASection 6 refer to net or gross?Table A-6 is requesting the total gross generation of per unit.A7-1 If a once-through cooling system has no blowdown, can aplant enter zero for amount of wastewater generated andduration/frequency?Question A7-1 requests the typical amount of process wastewatergenerated OR blow down from the cooling system. Once throughcooling water is considered a process wastewater. Therefore, theplant should supply the generation, duration, and frequency of theonce through cooling water.A7-1 For Question A7-1, Table A-10, should I include anychemicals that are added to the boilers in the heat recoverysteam generators (HRSGs)?In Part A Section 7, EPA is requesting chemical additions to coolingwater systems. This section does not include reporting of anychemical addition to the condensers within the boiler or the HRSGs.However, chemicals added directly to the cooling tower, the closedcooling water system which empties into the cooling tower, or anyother parts of the cooling water system should be included.A7-1 If a plant has four turbines and four condensers but justone cooling water pond. Should this be considered as oneor four cooling systems in Part A, Section 7? If it isconsidered four systems, all four systems would have thesame data.You may report this as one cooling system (for example, if all fourunits are serviced by the same once through cooling water) or fourseparate cooling systems (if they are operated independently),whichever makes more sense for your plant.Version 2July 28, 2010Frequently Asked Questions - TechnicalP. 6 of 19Question # Question ResponseA8-1 If a plant has a combined cycle unit with three generators(two gas turbines and one steam turbine), how should theycomplete Table A-11?First, the plant should identify the combined cycle unit (two gasturbines and one steam turbine) as one steam electric unit and NOTthree separate steam electric units in Question A6-1 (Table A-8).Then, in Question A8-1 (Table A-11), the plant should report thetotal fuel usage for the combined cycle unit as a whole (the two gasturbines and one steam turbine).A8-1 Should I enter an instantaneous or annual number for"BTU generated ..."?Enter the total BTU generated for 2009 (i.e., the annual total not aninstantaneous rate).A8-1 What should be provided for the "BTU generated by gas",and is there a difference between BTU generated andamount of natural gas?The BTU generated by burning the gas and the amount of natural gasburned are two separate requests in the questionnaire. The BTUcontent of the gas and the amount of gas burned in 2009 can be usedto determine the BTU generated.A9-1 How should the facility report different NOXcontrolsystems for different boilers serving the same generatingunit, particularly if the boilers have the same type ofsystem (e.g., overfire air)?Complete a row for each generator/boiler combination and add acomment on the Comments page.A10-1 If a plant has one type of flue gas mercury control on eachunit, do I complete Table A-14 for each control on eachunit?The plant should only report the types of flue gas mercury controlsystems at their plant once, and then use the third column todistinguish which steam electric units have that type of control.Part BVersion 2July 28, 2010Frequently Asked Questions - TechnicalP. 7 of 19Question # Question ResponseB1-1 Is the ash produced by the addition of limestone to acirculating fluidized bed boiler considered an FGDmaterial? No water is involved in any part of the process.The addition of limestone to the CFB boiler does not constitute anFGD system for the purpose of this questionnaire; therefore, the ashproduced is not considered an FGD material. If no FGD systems arepresent at the plant, answer QB1-1 as "no" and the plant does nothave to respond to the rest of Part B. Additionally, the plant shouldadd a comment to Part A, Question 6-1 indicating which generatingunits are CFB boilers and have limestone added.B6-2 TKN and Nitrate/Nitrite analytes do not have CASnumbers. What should be reported?Enter "No CAS" for these analytes.General If both bottom ash and fly ash are conveyed and stored dryin combination, how should Part C be completed?Complete Section 3 (bottom ash) rather than Section 2 (fly ash) andadd comments to both sections that the plant has a combined fly andbottom ash conveyance and storage system.General The plant may not have costs and design records prior tothe last 5-7 years for ash handling systems, or othersystems at the plant.Cost questions only require information for systems installed on orafter January 1, 2000. In the event that exact data are not available,provide your best engineering estimate and note the methods youused in the Comments page at the end of the Part.C1-1, C1-3 What is the difference between "ash" referenced in C1-1and "fly ash" referenced in C1-3?"Ash" in question C1-1 refers to any ash that is created by the unit(i.e., fly, bottom, economizer). EPA included this question to directplants with units that do not produce ash to skip completion of PartC. Question C1-3 "fly ash" is ash that is carried out of the furnace bythe gas stream (see the Questionnaire Instructions for a definition offly ash).Part CVersion 2July 28, 2010Frequently Asked Questions - TechnicalP. 8 of 19Question # Question ResponseC2-1 What is LOI and do I have to report it if I have nevermeasured it before?The loss on ignition (LOI) is defined as a measure of the amount ofunburnt fuel remaining in the ash/residue from the combustionprocess. For the combustion of coal, the loss on ignition is a measureof the carbon content remaining in the ash. The loss on ignition is aproperty of the ash (typically reported in mass percent) that isaffected by the type of coal burned, type of boiler, and certain typesof NOx controls (specifically, over fire air systems, and low NOxburners). Please use the following link for further backgroundinformation and to see the methods for measuring LOI provided bythe American Society for Testing and Materials (ASTM);http://www.astm.org/Standards/D7348.htm. Please note that EPA isnot requiring your company or plant to perform non-routine tests ormeasurements solely for the purpose of responding to thisquestionnaire (with the exception of Part G). In the event that exactdata are not available, provide your best engineering estimate andnote the methods you used in the Comments page at the end of thePart.C2-6 What is a wet vacuum pneumatic system? A wet vacuum system (pneumatic) refers to a system where thevacuum that pulls the ash is created from a water source (i.e., thesluice water). A completely dry pneumatic system does not use waterto create the vacuum or pressure that is the motive force for the ash.C2-6 How should this question be answered for a pneumaticsystem which is not wet?Depending on the configuration of your system, you would select"Dry vacuum system," "Pressure system," or "Combinedvacuum/pressure system" for "Type of Fly Ash Handling" in Q C2-1,then select "No" in Q C2-2 and Q C2-6.Version 2July 28, 2010Frequently Asked Questions - TechnicalP. 9 of 19Question # Question ResponseC5-4 Is there a mismatch of pond IDs available in Table A-4versus the dropdown box in Question C5-4?No. The pond IDs in Table A-4 refer to individual ponds. The pondID in Question C5-4 refers to the pond system IDs identified in TableD-1.Part DGeneral If the plant sends the wastewaters to a pond/impoundmentthat is located at and owned by another facility, does theplant have to fill out the information in Part D.Throughout the questionnaire, the plant should report that thewastewaters generated at the plant are sent off-site to a publicly orprivately owned treatment works, as appropriate. The plant shouldalso answer "no" to QD1-1 if no other pond/impoundments are usedor planned to be used (or begin construction/installation of) at theplant. The plant should make a comment in Part D explaining thesituation, reporting the types of wastewaters being sent, and whetherthe plant shares the cost of treatment with the other companyoperating the pond/impoundment.D2-6 If the plant has a pond that is primarily used for otherwastewaters at the facility (e.g., coal pile runoff, rainfall,floor wash water), should it be included in Part D if asmall amount of ash may be collected with the floor washwater?No, the pond does not have to be included in Part D.D3-1 When submitting the block diagram(s) for Question D3-1,what is meant by the pond/impoundment or wastewatertreatment system ID and the block diagram number?Use the checklist provided below D3-1 to complete the blockdiagram. The pond/impoundment system or wastewater treatmentsystem ID is the ID from the 1st column in Tables D-1 and D-2. Forexample, POND-1, POND-2, WWT-1. The block diagrams should benumbered in the upper right corner. The 1st block diagram should benumbered D-1, second D-2, etc. D-1 and D-2 are block diagramnumbers.Version 2July 28, 2010Frequently Asked Questions - TechnicalP. 10 of 19Question # Question ResponseD4-5 If the plant is currently dredging the pond, should theinformation be reported in Question D4-5?Yes, enter 2010 for the year dredged and supply all of theaccompanying information to the best of your ability (i.e., amount ofsolids dredged, number of days dredged), as well as all informationfor dredge operations in the last five years. If necessary, use thecomments section to document any notes about the dredging.NA If I have a landfill that is currently under construction, thathas not been previously in use (i.e., no materials added tothe landfill), do I complete Part F?Planned landfills, including those under construction that have nothad any materials added to date, are not required to be reported inPart F.General If I do not have a leachate collection system, but I do havestormwater runoff ponds and groundwater monitoringwells, do I have to answer Part G?The plant should not respond to Part G for groundwater monitoringwells as they are not a form of leachate collection. Stormwater runoffponds should only be included if the pond also collects leachate.Please contact the helpline for further clarification regarding thesituation at your facility.General If I have a pond configuration including two or moreponds, where should I collect leachate?Instructions to Question G3-1 state that the plant should collectsamples from eachleachate collection point for eachpond/impoundment and landfill. If a plant determines that a samplefrom one or more collection points are representative of an individualpond/impoundment or landfill, they may collect samples from onlythe representative sample point(s)for that pond/impoundment orlandfill.Section 4 Can the plant use local rainfall records to reportprecipitation instead of directly measuring it on site?Local rainfall measurements are acceptable.Part FPart GVersion 2July 28, 2010Frequently Asked Questions - TechnicalP. 11 of 19Question # Question ResponseG4-1 The question asks for flow rate of the leachate stream, butthere is no entry field in the table for flow rate or units.Respondents should provide this information in the Commentssection for Part G.G5-1 Shouldn't the "Type and Amount of Waste" column referto "FGD Calcium Sulfite - Not Pozzolanic", rather than“FGD Calcium Sulfate – Not Pozzolanic”?If a pond/impoundment contains FGD calcium sulfite – notpozzolanic, respondents should select the "Other" checkbox and type“FGD calcium sulfite – not pozzolanic” as the description.Part HNA I received Part H on my disk, but I do not have any nuclearunits. What should I do?Answer "no" to question H1-1. You do not have to provide anyother information in the Part H file.H1-2 What is meant by the term "service water treatmentsystems"?A service water treatment system would be a system that treats lakeor river water, so that it could be used in the boiler or for other onsiteuses.I5-4 The table is requesting annual fuel costs in dollars, but anumber greater than 8,760 cannot be entered into the cells.Respondents should download the new revised version of Part I fromthe EPA website.Part IVersion 2July 28, 2010Frequently Asked Questions - ApplicabilityP. 12 of 19Question ResponseIf a plant has two coal units and two gas units, do they have to completeVersion 2 of the questionnaire for all units or can they complete Version2 for the coal units and Version 4 for the gas units?Respondents should complete Version 2 of the questionnaire for all unitsat the plant. There will be many questions that apply to all the units. Forquestions that only apply to certain types of units, the directions in thequestionnaire will clearly indicate which units plants should include intheir response.If the plant’s SIC is 4961 (steam and air conditioning supply) and theplant’s primary purpose is to provide steam, does the plant need tocomplete the questionnaire? The plant does have electric generationcapacity.The first questions in Part A of the questionnaire specify that if a plantdoes not meet certain requirements they do not need to complete theremainder of the questionnaire. For example, in this case, question A1-11 asks if the primary purpose of the plant is to generate electricity. Youwould state no, designate the primary purpose in the box provided, andnot complete the remainder of the questionnaire. The completedquestionnaire and signed certification must be returned to the addressspecified in the questionnaire instructions.If the operating company needs to get information from other owners ofthe plant, should the owners send the operating company the completedinformation or can each owner send the information to EPA directly?Respondents should NOT submit the questionnaire to EPA in pieces.Operating companies should obtain the required information fromowners, use this information to complete the questionnaire, and submitone complete copy to EPA.If a plant is scheduled for retirement, do they need to complete thequestionnaire?In Part A, question A1-6 asks about the retirement date and states thatplants that will be permanently retired by December 31, 2011 will notneed to answer questions beyond A1-6. The completed questionnaireand signed certification must be returned to the address specified in thequestionnaire instructions.If the plant only received certain files on their disk, are they required todownload the remaining files from EPA's web site?If the facility received Version 2, 3, or 4 of the questionnaire, they areonly required to complete a subset of the questionnaire. Please see yourcover letter or the general instructions for more details.Version 2July 28, 2010Frequently Asked Questions - ApplicabilityP. 13 of 19Question ResponseTwo of our facilities utilize the same generating technology andequipment and burn the same fuel; therefore, the plants have identicalinformation. Do we have to complete both questionnaires?The questionnaire must be completed for both facilities.If the plant stopped burning coal in the middle of 2009 and is in theprocess of switching to a different fuel source such as biofuels, do theyneed to complete the questionnaire?The plant must complete as much of the questionnaire as possible for allmonths it operated the coal units in 2009.If the plant's coal unit shut down in May 2010, and the plant is building anew gas unit, should the questionnaire be answered for the coal or thegas unit?The plant must complete the questionnaire for the coal unit because itwas in operation in 2009. The plant must also include all of theinformation available for the planned gas unit.Does surface water include on-site ponds/impoundments or are only offsite receiving waters included?On-site ponds/impoundments that are part of a wastewater treatmentsystem are not generally considered surface water, unless they areconsidered as such by the permitting authority for the purposes of theClean Water Act. Whether the location is on or off site is not thedetermining factor, because it is entirely possible that surface watersmay be located within the boundaries of a facility.Version 2July 28, 2010Frequently Asked Questions - GeneralP. 14 of 19Question ResponseEPA distributed this questionnaire to all coal-fired power plants and a subset ofother power plants that are likely subject to the Steam Electric Power Generatingeffluent guidelines (40 CFR Part 423).
