Emission Release Point ID. Use the dropdown menu to select the PCWP process unit Emission Release Point ID tested. Reenter the Emission Release Point ID on a new row for every emissions test report and pollutant test that is provided for the release point. The Emission Release Point ID drop-down menu list is based on the PCWP Process Unit IDs you specified in the EquipDetail tab. The Emission Release Point ID you enter will prepopulate the shaded columns F, G and H containing the process unit ID(s), process unit type(s), and product(s) previously entered in the EquipDetail tab.
Air Pollution Control System and Inlet/Outlet. Specify the air pollution control system used during the emission test. This is the control system affecting emissions upstream of the emission point tested. For example, if a WESP/RTO system was tested at the WESP outlet prior to the RTO, enter "WESP" as the control system testing so it is clear that emissions were not influenced by the RTO. If the WESP/RTO system was tested at the RTO outlet you would enter "WESP/RTO" as the control system to reflect that emissions were influenced by both the WESP and RTO.
Specify whether inlet or outlet data are provided for the air pollution control system listed. If no control system was used during the test, select "Outlet." If the test measured percent reduction across the control system, select "Inlet and Outlet."
Pollutants and Test Methods. Select (or write in) the pollutant tested and the associated test method in columns K and L. The menu choices for pollutants to include on each row are:
Methanol
MDI
Formaldehyde
PM
Acetaldehyde
PM10
Acrolein
PM2.5
Phenol
Opacity (Method 9)
Propionaldehyde
HAP metals
THC (as carbon)
POM
THC (as carbon) minus methane

THC (as propane)

For a "total HAP" test, defined in the PCWP NESHAP as the sum of the 6 HAP: acetaldehyde, acrolein, formaldehyde, methanol, phenol, and propionaldehyde, you would enter 6 rows for each emission point tested - one row for each of the 6 HAP compounds included in the test.
For tests involving "other HAP" included in Appendix 3, write the pollutant tested in the "Pollutant" column - selections from the menu are limited for simplicity.
Tests involving HAP groups measured by the same test, including Method 29 HAP metals or Method 429 POM/PAH may be listed as "HAP metals" or "POM" on one row instead of listing every specific compound. The EPA will extract speciated data from the emissions test report at a later date.
Several "Pollutant" menu choices are available for THC:
Select "THC (as carbon)" for Method 25A tests where the result was reported as carbon consistent with how THC is measured to show compliance with the PCWP rule.
Select "THC (as carbon) minus methane" for Method 25A tests that involved simultaneous methane testing a where the result was reported as carbon minus methane. The PCWP rule allows subtraction of methane from the THC measurement.
Select "THC (as propane)" for tests where the result was reported as propane. While the EPA is not requesting VOC data obtained using the OTM-26 calculation procedure, the EPA is interested in receiving Method 25A THC (as propane) measurement data obtained for purposes of OTM-26. We can convert Method 25A results reported "as propane" to an "as carbon" basis.
The "other process units/pollutants included in the test report" column asks for you to list any additional PCWP process units or pollutants for which test data are available in the test report supplied. You do not need to note data for process units outside of the PCWP source category such as boilers. However, please note if emissions data for PCWP process units or pollutants beyond those requested are in the test report (e.g., dryer NOX or SO2 data). Although the EPA is not requesting these data it will be helpful to know which test reports contain data for additional pollutants. The EPA can use this data to evaluate secondary air impacts from control devices used to comply with the PCWP NESHAP.
Describing the Emission Unit Configuration. The EmTest tab contains multiple questions relating to the emission unit configuration during the test. One question asks if the emission point tested is "isolated from other nearby emission points" to provide a space for respondents to indicate if nearby emission sources may have influenced emissions during the test. This question is of importance for process units where emissions are not deliberately captured or isolated from other units through integral ductwork (e.g., for most dryers) or an enclosure (e.g., for a reconstituted wood products press). Select "Yes" if the emission point tested was isolated from other emissions points (e.g., via use of in-stack test ports). Select "No" if the emission point tested was not isolated from emissions from other nearby process units. An example of an emission point that is not isolated could be a fugitive vent tested that was very likely to have been drawing in air from multiple process. You are asked to explain how nearby emission points may have influenced the test results in the next column. Select "Unknown" if you are unsure.
Include results of capture efficiency testing and discussion of measures taken to isolate the process unit emission point tested from other nearby process unit emission points, as applicable. The EPA is also requesting reports of capture efficiency testing in conjunction with process units such as presses where a capture demonstration was required. Examples of capture demonstrations include use of a permanent total enclosure or wood products enclosure meeting the design criteria in the PCWP rule, 40 CFR part 51 Method 204A-F testing of a temporary total enclosure, and the use of the tracer gas method in Appendix A of the PCWP rule (subpart DDDD). Note that you are asked to provide the percent-capture result from such testing in the Press, BC, or EWPPress tabs (as applicable) in addition to submitting the capture testing report in conjunction with reports supplied with the EmTest tab.
The yes-no question asking if the "process unit production rate specified in the test report" is included to allow the EPA to easily determine which test reports may be useful for developing emission factors.
A question and explanation column asking if "the configuration of the process unit, combustion controls, collection system, or APCD changed since the test was conducted" is included to indicate whether the emissions test data remain representative of your current operations. Emission test reports for previous configurations are optional, but are requested because they may provide insights into emission reductions that may be gained through various process changes. For example, if a facility supplies test reports from before and after implementation of the CARB and TSCA rules limiting formaldehyde from panel products, these data will help the EPA evaluate the effect of such changes on PCWP press and board cooler emissions. Facilities may (but are not required to) supply emission test reports for configurations prior to installation of controls to meet the PCWP NESHAP.
An optional "process testing notes" column is included to allow space for you to indicate any information you believe would be useful for the EPA to know about the emissions test conducted.
Testing Frequency and Cost. Questions regarding testing frequency for the process unit and pollutant are asked to gauge how often facilities are required to test. Emissions testing costs are requested to help inform the EPA for purposes of evaluating ongoing emissions testing costs.
b. 	Emissions Estimates (HAP Emissions) tab
	1. HAP Emissions Tab Overview
Hazardous air pollutant emission estimates for the PCWP source-category process units listed in Appendix 2 are requested in the HAP Emissions tab in PCWP_survey.xlsx. Emission estimates are requested in units of tons per year (tons/year) and maximum pounds per hour (lb/hr). Emission estimates should be representative of actual mill production rates in the 2016 base year for the ICR.
Emission estimates must be provided in the HAP Emissions tab for every Release Point ID that emits HAP. Before this tab can be completed, Release Point IDs must be supplied in your EquipDetail tab responses. The Release Point IDs are carried through to the ReleasePt tab and then into the HAP Emissions tab. The EPA's risk model will combine the stack parameters and longitude/latitude coordinates specified in the ReleasePt tab with the emissions estimates specified in the HAP Emissions tab to calculate residual risk. Therefore, it is important that the information provided for each Release Point ID is as accurate as possible.
As noted above, the HAP Emissions tab is prepopulated with the Release Point IDs and other process unit descriptors from the EquipDetail tab. The process unit type and process unit ID are provided to aid in estimating emissions. Emission estimates using emission factors are often developed on a process unit basis, but must be apportioned to the appropriate Release Point IDs as described below.
Fifty rows are allotted for each Release Point ID in the HAP Emission tab. Each row will be used for a single pollutant that you select from the menu in column I. A block of 50 rows is provided for each emission release point to ensure there are enough rows for every pollutant. However, most release points will have far less than 50 pollutants. You may consider hiding the extra empty rows for easier viewing. Blank rows are provided at the end of the sheet in the unlikely case a particular release point requires more than 50 pollutant rows.
You are required to populate the columns for Start and End date, Pollutant, Method for Determining Emissions, Estimated Actual Emissions (tons/year), Estimated Allowable Emissions (tons/year), and Estimated Maximum Emissions (pounds/hour) as described in Section D4b2 below. The remaining columns in the HAP Emissions tab are for the Provisional Calculation Tool, which is an optional emission-factor calculation resource you may choose to use for estimating emissions in the absence of more-accurate site-specific information. Instructions for using the Provisional Calculation Tool are provided in Section D4b3 below. The columns and instructions pertaining to the Provisional Calculation Tool can be ignored if you are not using the tool.
Resources of Estimating HAP Emissions. Appendix 9 provides the list of the 187 HAP. Site-specific HAP emissions measurement data are the preferred basis for your emission estimates. Emission estimates may be calculated based on emission factors and site-specific operating data in the absence of measurements. If required by your delegated authority, you may already have an up-to-date HAP emissions inventory for your facility that could be used as the basis for completing the HAP Emissions tab.
In addition, you may find some HAP emissions estimates for your facility submitted by your state or local air pollution control agency as part of the EPA's National Emissions Inventory (NEI). State and local air agencies are not required to supply HAP emissions data through the EPA's Emissions Inventory System used in creation of the NEI but may do so on a voluntary basis. The most recent version of the NEI is available at https://www.epa.gov/air-emissions-inventories/2014-national-emissions-inventory-nei-data for 2014. The NEI data set contains varying levels of HAP emissions detail for different PCWP facilities and would require substantial review and augmentation for purposes of the PCWP NESHAP residual risk review. Although the EPA determined that more recent and complete emissions estimates are preferable for the PCWP residual risk review, some facilities may choose to review their NEI data set as part of creating their 2016 emission estimates for inclusion in the HAP Emissions tab.
Appendix 10, Resources for Estimating Emissions, contains references to documents containing emission factors that you may find useful for developing your emission estimates. Furthermore, a Provisional Calculation Tool has been provided within the HAP Emissions tab for facilities that may not otherwise have a HAP emissions inventory and would need to create one for purposes of the ICR. The tool operates by looking up publicly-available emission factors based on the SCC code associated with each emission release point ID. Most of the emission factors in the tool are based on AP-42. Use of the provisional calculations is optional. You may use the provisional calculations for any pollutants for which you do not have site-specific or other more-representative emissions data. The provisional calculations should not be used when more-representative site-specific data are available.
To accompany the Provisional Calculation Tool, the EPA has provided a crosswalk of SCC codes indicating pollutants with publicly-available emission factors (e.g., from AP-42 Chapter 10), referred to as the "SCC Crosswalk." in Appendix 8 of these instructions.
CBI. There is no red CBI block in the HAP Emissions tab because emissions data are not considered to be CBI. If you plan to use the provisional calculations, it is important that you do not redact CBI production rates from the spreadsheet until after you have copied/pasted (as values) the results of the provisional calculations. Otherwise the necessary production data will not be available and the calculations will not work.
	2. Completing the Required Fields
To complete the required fields in the HAP Emissions tab, first note the prepopulated Release Point ID. The Process Unit Type and ID are also prepopulated. Emissions estimates are required for each Release Point ID. However, a release point may combine multiple process units.
Release Point ID. Looking at each release point ID, consider the following:
Are there HAP emissions associated with the Release point ID? If you do not already have site-specific data, you may find the SCC Crosswalk helpful for identifying HAP compounds expected to be emitted. The SCC for each emission release point is prepopulated in column P of the HAP Emissions tab for reference. If no HAP emissions are known to be associated with a Release Point ID, then you may select "NA-No known HAP emissions" from the "method for determining emissions" menu in column K and leave the remaining required columns blank.
Does a process unit have more than one Release Point ID? You can identify process units with multiple release point IDs by checking to see if the same Process Unit ID appears in more than one block of rows. If so, then the process unit most likely has multiple emission release points. In this case, emission-factor estimates for the whole process unit may need to be apportioned across the different Release Point IDs using engineering judgement. For example, a hardwood veneer dryer may have two zones with separate stacks with 50% of the dryer emissions occurring at each stack. In this case, you would assign 50% of the emissions to each Release Point ID. If you are using the Provisional Calculations, you would apportion emissions using the "release point emissions apportionment fraction" column.
Does the same Release Point ID appear in more than one block of rows in column F? If so, it is likely that multiple process units vent through the same emission point. In the HAP Emissions tab, you would provide an emission estimate for each process unit routed to the emission point. For many pollutants, it is likely that you would be estimating process-unit level emissions using emission factors and control efficiency. The emission estimates for multiple process units venting through the same release point would be additive, meaning the sum of the process-unit level emissions would be used by the EPA's residual risk model for the shared emission release point.
If you have stack test results for a pollutant reflecting total emissions from all process units venting to the release point, then you would need to apportion the total measured emissions across all process units venting to the release point using engineering judgment. For example, you might apportion emissions measured at the RTO outlet for 3 dryers using the throughput from the each to assign a portion of the measured emissions to each dryer.
For combinations of different types of process units with measured emissions that are cannot reasonably be apportioned (e.g., a press and a dryer venting to one release point), you could enter the total emissions on one row (for unit X) and indicate in the "pollutant" column (for unit Y) that "combined emissions are provided for process units X and Z in the row for unit X." In the comments column for unit X, you could also indicate that "This row contains combined emissions for process units X and Y." These notes would alert the EPA to the fact that combined emissions are provided in one row.
Regardless of the approach you choose, please take care not to double-count emissions by applying the measured emissions for a release point multiple times without apportioning properly.
Start/End dates. Enter the start and end dates for the emission estimates provided in YYYYMMDD format. For example, enter 20160101 to 20161231 for January 1 to December 31, 2016.
Pollutant. Select each pollutant emitted from the menu in the "Pollutant" column. If the pollutant is not listed in the menu, you may write it into the Pollutant column. Space if provided for 50 pollutants which will be more than enough rows for most emission release points. Use the blank rows at the bottom of the table should you need to add more than 50 pollutants for a give Release Point ID.
The "pollutant type note" column is needed for the provisional calculation formulas and will automatically display "organic," "metal," or "user-added" based on the pollutant you enter provided you use the exact spelling from the pollutant menu. There are no provisional calculations for user-added pollutants. If you intend to use the provisional calculations, please verify the "pollutant type note" column updates so the provisional formulas will work properly. Otherwise, you may ignore the "pollutant type note" column.
You may find the SCC crosswalk provided in Appendix 8 helpful for identifying pollutants based on process unit type. The SCC crosswalk lists the pollutants with available provisional calculations. Pollutants for which all data used in evaluating emission factors was non-detect are not included in the provisional calculations. It is not necessary to include emission estimates based on measurements that were always below the detection limit.
Certain pollutants may require speciation for more accurate risk modeling results, as described later in this section.
Method for Determining Emissions. For each pollutant entered, indicate the method used for determining actual emissions by selecting one of the following menu choices:
01 - CEMS
08 - Default Category Emissions Profile
02 - Source Test
09 - Manufacturer Specification
03 - Emission Models
10 - MSDS
04 - Information Collection Request
11 - Engineering Judgement
05 - Material Balance
99 - PCWP Provisional Calculation
06 - Speciation Profile
NA-No known HAP emissions
07 - Emission Factor

The "Method for Determining Emissions" column corresponds with the actual emissions column; there are no corresponding columns to mark for allowable or maximum emissions.
Actual, Allowable, and Maximum HAP Emissions. Actual HAP emission estimates (tons/year) must be provided for each individual HAP compound. Actual emissions account for the effects of any APCDs that may be installed to reduce emissions. For example, if an RTO reduces uncontrolled emissions you would provide emissions at the RTO outlet.
Allowable emissions data are also requested. Allowable emissions include emissions (tons/year) that are allowed under the PCWP NESHAP. For example, if actual emissions are 10 tons/year considering controls and compliance margin, but the facility is allowed to emit 15 tons/year under the PCWP NESHAP emission limit, then allowable emissions would be 15 tons/year. If the PCWP NESHAP does not currently limit HAP emissions for a given process unit, then the allowable emissions would equal the actual emissions.
Maximum emissions on a short-term basis (in lb/hr) are also requested for purposes of acute risk modeling. An example of maximum hourly emissions may be short term (peak) uncontrolled emissions during peak production rates or during a time when the RCDME is used (e.g., when the 90% control efficiency is not being achieved).
Enter your actual, allowable, and maximum HAP emissions estimates into columns M-O. As noted previously, site-specific emissions measurement data are preferred but emission estimates may be calculated based on emission factors and site-specific operating data, mass balance, or other means in the absence of measurements. If you use the Provisional Calculation Tool described below for the actual, allowable, or maximum emissions, after reviewing the calculated emissions for representativeness, you would paste the resulting calculated emissions as values into columns M-O.
Speciation of Selected HAPs. If emitted, compounds such as mercury, chromium, PAHs, and dioxin/furan would require speciation for more accurate risk modeling. If not speciated, the most potent form of the compound will be assumed by the EPA for risk modeling.
The different oxidation states of mercury compounds vary in toxicity, but also in exposure pathway (e.g., inhalation, ingestion). The most common mercury species are divalent mercury (Hg+2) (including both particulate and gaseous forms) and elemental gaseous mercury (Hg0). If mercury is emitted, in the absence of data on the specific oxidation state, the mercury emissions estimate can be speciated onto different pollutant rows in the HAP Emissions tab using the NEI default multipliers of 0.2 for particulate divalent mercury (pollutant code 202), 0.3 for gaseous divalent mercury (pollutant code 201), and 0.5 for elemental gaseous mercury (pollutant code 200).
For chromium, the default multipliers for PCWP SCC codes are 0.28 for hexavalent chromium and 0.72 for trivalent chromium.
Polycyclic organic matter is comprised of a large number of individual compounds, which can be divided into the subgroups of polycyclic aromatic hydrocarbons (PAHs) and PAH-derivatives. Each compound has its own toxicity level and can vary in exposure pathway. If POM data are reported, speciation into individual PAHs is needed, if a speciation profile is available.
Similarly, if dioxin/furan is emitted from any PCWP process units, individual dioxin/furan congeners, specifically those used to determine the 2,3,7,8-TCDD toxic equivalency (TEQ), are needed for the EPA's risk analyses. The congeners of interest are listed in Appendix 10, along with the toxic equivalency factor (TEF) used to express the mass of each congener in terms of its 2,3,7,8-TCDD TEQ.
	3. Using the Optional Provisional Calculation Tool
The two sections to the right of the HAP emission tab contain the Provisional Calculation Tool Parameters and the Provisional Emissions Calculations for optional use in the absence of more accurate data. Select "Yes" in the "View Provisional Emissions Calculations" column so the emissions calculations formulas will appear. Columns within these sections that are shaded light purple include operating data prepopulated from elsewhere in the ICR spreadsheet. Purple columns are not to be edited, but have been provided to allow you to review the calculation parameters for representativeness and accuracy before deciding whether to use each provisional calculation. To use the provisional calculations, you will enter information into the white columns for the release point apportionment fraction and control efficiency. The provisional calculations are based on publicly available emission factors (e.g., emission factors from AP-42 most closely associated with the applicable SCCs) and production data and control system data provided throughout the ICR spreadsheet. Within the provisional calculations, you have the choice of entering a more representative emission factor than the factor provided in the optional site-specific numeric emission factor column.
Caution! The Provisional Calculation Tool is comprised of formulas that extract respondent-provided data from the ICR and couple the data with the most closely related publicly available emission factors for each SCC to estimate emissions. Respondents using the tool are responsible for ensuring correct parameters are input into the tool and reviewing the resultant calculations for representativeness of their operations. Failing to input correct parameters will result in flawed emission calculations. The tool is only to be used in the absence of more site-specific, representative information.

Respondents using the tool are responsible for ensuring correct parameters are input into the tool and reviewing the resultant calculations for representativeness of their operations. Failing to input correct parameters will result in flawed emission calculations. The tool is only to be used in the absence of more site-specific, representative information.

If you are using the provisional calculation for actual emissions, select "99 - PCWP Provisional Calculation" in the column asking for the method used to determine emissions. You may use a provisional calculation for allowable or maximum emissions even if you do not use it for actual emissions.
The block of columns labeled "Provisional Calculation Tool Parameters" beginning in column P contains prepopulated production parameters used in the calculations. You will need to review the prepopulated information in the light purple shaded columns and enter parameters into the white columns in this area.
SCC, most closely related available emission factor description, and emission factor source  -  The SCC for each Release Point ID in the HAP Emissions tab is prepopulated with the SCC you selected in the ReleasePt tab.
The column labeled "Most Closely Related Available Emission Factor Description" provides a description of the set of emission factors used in the provisional calculations for each SCC. This column may differ from the SCC description because AP-42 emission factors are not available for every PCWP SCC. The list of SCCs was expanded in recent years to encompass more variations in PCWP process unit characteristics. In selecting the emission factors for each SCC, if no set of emission factors was available for a given SCC, then the most closely-related set of emission factors was used in the provisional calculation tool erring on the conservative side such that emissions would be more likely to be overestimated for purposes of the EPA's risk analysis than underestimated. Before deciding whether to use the provisional calculations, you need to review and consider whether the most closely related available emission factor provided is sufficiently representative of your operations. If you conclude that the emission factor is not representative, then you may enter a more-representative emission factor into the "Site-specific Numeric Emission Factor (Optional)" column or opt to use an approach other than the provisional calculations to provide your emissions estimates.
The "Organic HAP Emission Factor Source" column provides a reference for the most closely related organic HAP emission factor. The metals emission factors did not originate from AP-42, but were derived from wood/bark residual fuel analysis data collected from the forest products industry for boilers.
Throughput and units of measure  -  The numeric value for the process unit throughput and the throughput units of measure are prepopulated into columns S and T from the entries you provided previously in process-specific tabs including the various dryer, press, and other equipment tabs. Please review the numeric throughput values and units of measure provided to ensure they are representative of the process unit for purposes of calculating emissions. If not representative, these parameters would need to be changed in the relevant tab or a method other than the provisional calculations needs to be used to estimate emissions.
Operating Hours and APCD System  -  The process unit operating hours (hr/yr) and APCD system listed in the EquipDetail tab for the Process Unit ID are prepopulated into the columns U and V. The value for operating hours is used in the provisional emissions calculation. The APCD system is provided for reference to assist you in entering an estimate for the control efficiency. Please review the values provided to ensure they are representative of the process unit for purposes of calculating emissions. If not representative, these parameters would need to be changed in the EquipDetail tab or a method other than the provisional calculations needs to be used to estimate emissions.
Release point emissions apportionment fraction  -  The release point emissions apportionment fraction is used to apportion emissions from a single process unit across multiple release points. Emissions are calculated for a specific process unit type (using formulas provided in this section below). However, it may be necessary to divide the process unit emissions across multiple release points. For example, for a process unit with 2 stacks you might enter 0.5 to apportion half of the calculated emissions to each stack. In this example both stacks would appear as separate rows in the HAP emissions tab. An "IF" formula is included in the release point emissions apportionment fraction column to default the release point emissions apportionment fraction to 1 (or 100%). If you need to apportion emissions across multiple release points, simply overwrite the formula with the desired decimal fraction. The value you enter may not exceed 1.
Estimated combined HAP collection-control efficiency  -  If the process unit emission point is controlled to reduce HAP emissions, you would enter a combined collection and control efficiency. For most process units, the collection efficiency is assumed to be 100% (e.g., for dryers or presses with permanent total enclosures). However, if you are capturing, for example, only 80% of the emissions for a given process unit and delivering the captured emissions to control device that reduces the emissions by 90%, you would enter 0.8 x 0.9 = 72% for the combined collection and control efficiency. The value entered for the combined organic collection-control efficiency is a decimal percentage that cannot exceed 1 (for 100%). Leave the value blank or enter 0 for uncontrolled units.
Estimated PM control efficiency and Direct wood-fired dryer MMBtu/hr (for metal HAP only)  -  The provisional calculations estimate the potential for metal HAP emissions from direct wood-fired dryers. Metal HAP, as indicated in the "pollutant type note" column, require a different calculation formula than organic HAP. (The provisional calculation formulas are provided later in this section.) The provisional metal HAP emissions estimates are calculated using emission factors derived from wood/bark residual fuel analysis data, PM control device efficiency, and the MMBtu/hr of wood firing required by the dryer. The "estimated PM control efficiency" column will turn white when metal HAP pollutants are entered in the pollutant column and the calculated MMBtu/hr associated with wood firing for the dryer will appear in the purple "Direct wood-fired dryer MMBtu/hr" column. Enter an estimated PM control efficiency across the APCD system as a decimal percent (not to exceed 1) for use in the provisional HAP metals emissions estimates. If no site-specific (or otherwise representative) information is available you may assume 0.99 for wet or dry ESPs or baghouses, 0.95 for wet scrubbers, or 0.90 for cyclone or multiclone mechanical collectors. It may be assumed that HAP metals are emitted in particulate form and therefore are controlled as PM, with the exception of non-particulate (gaseous) forms of mercury. Enter zero for the PM control efficiency for non-particulate (gaseous) forms of mercury.
The MMBtu/hr value in column Z is pre-populated based on the total heat input capacity reported for wood or bark firing calculated from the information provided in the in the DFDryFuel tab. The responses provided in the DFDryFuel tab for MMBtu/hr, primary and supplemental fuel type, and approximate percent of annual heat input capacity are used to calculate the MMBtu/hr provided in the HAP Emissions tab. Only wood/bark fuels are included in the provisional calculation because the PCWP SCCs do not distinguish among fuels other than wood and natural gas, the most common dryer fuels in the PCWP industry.
The "Direct wood-fired dryer MMBtu/hr" column will remain blank if the pollutant entered on the row is not a metal HAP, or if no information is included in the DFDryFuel tab. For direct-fired dryers burning fuels other than wood, the wood-fired MMBtu/hr displays as zero, resulting in zero emissions. If you have HAP metals emissions estimates for direct-fired dryers burning non-wood fuels, then those emission estimates can be entered into the required columns of the HAP emissions tab directly without using the provisional calculations.
Emission Factors, Units, and Scalar  -  The default emission factor used in the provisional calculations appears in the "Provisional Numeric Emission Factor" column if a default emission factor is available. The corresponding units of measure for the default emission factor appear in the "Units for Numeric Emission Factor" column.
In some cases, there may be no emission factor available for use in the provisional calculations either because no HAP data were available for use in developing emission factors or because all of the HAP data evaluated were below the test method detection limit (i.e., reflected as "BDL' in AP-42). If no emission factor is available for a given SCC, then "No EF for SCC" will appear in the Organic HAP Emission Factor Source column (column R). If no emission factor is available for a particular combination of pollutant and SCC then "No EF for pollutant" will appear in the "Provisional Numeric Emission Factor" column (column AC).
If no default emission factor is available or you are aware of a more-representative emission factor that you would like to plug into the provisional calculation, then you may enter the updated emission factor into the "Site-specific Numeric Emission Factor (Optional)" column as long the units of measure for the emission factor correspond with the throughput units of measure for the process unit in column T. (If the units of measure do not match, simply convert the numeric value for the site-specific factor to get matching units. See the formulas for the provisional emission factor calculations below).
Prepopulated "emission factor scalar" and "scalar units of measure (UOM)" columns displayed available for situations where the units of measure for the available emission factor need to be converted to match the "throughput units of measure" column. A value of 1 and "unity" will appear when the units of measure match. When units do not match, the appropriate conversion to be applied will display.
Site-specific Numeric Emission Factor (Optional)  -  You may enter a site-specific emission factor to replace the default emission factor if desired as long the units of measure are the same. Supplying a site-specific emission factor is optional. It is imperative for the units of measure to be the same as the default provisional emission factor for correct results.
Provisional Calculated Actual Emissions  -  Formulas for the provisional actual emissions calculation (tons/year) are provided below.
HAP type
Default Emission Factor (EF) formula
Site-specific EF formula
Organic
S x W x (1-X) x AC / 2000 x AD
S x W x (1-X) x AA / 2000
Metal
Z x U x W x (1-Y) x AC /2000
Z x U x W x (1-Y) x AA /2000

Where:
S= Throughput (amount/yr), where "amount" is a specific production unit of measure
W = Release point emissions apportionment fraction (dimensionless)
X = Estimated combined organic HAP collection-control efficiency (decimal percent)
AC = Provisional Numeric Emission Factor (lb/amount)
AD = Emission Factor Scalar
AA = Site-specific Numeric Emission Factor (lb/amount)
Z = Direct wood-fired dryer (MMBtu/hr)
U = Process Unit Operating Hours (hr/yr)
Y = Estimated PM control efficiency (decimal percent)
2000 lb/ton
Provisional Calculated Allowable Emissions  -  Formulas for the provisional allowable emissions calculation (tons/year) are provided below. "Allowable" emissions consider the compliance margin between actual emissions and applicable emission limit. The provisional calculation estimates emissions based on the difference in actual vs. and allowable organic HAP control efficiency of 90 percent. Actual = Allowable if no organic HAP control is used, and for all metals because the PCWP rule does not currently limit metal HAP emissions.
HAP type
Default and site-specific EF formulas
Organic
If organic HAP control efficiency [X] equal or less than 90%,
allowable emissions [AG] = actual emissions [AF]*

If organic HAP control efficiency is greater than 90% and less than 100%, allowable emissions (AG) = actual emissions (AF) x (1-0.9)/(1  -  X)

If organic HAP control efficiency = 100%, allowable emissions [AG] = 10% of uncontrolled emissions calculated as:  AG = S x W x (0.1) x AC / 2000 x AD
Metal
allowable emissions [AG] = actual emissions [AF]
AF = Provisional Calculated Actual Emissions (tons/yr)
AG = Provisional Calculated Allowable Emissions (tons/yr)
*Facilities using the production-based compliance option or with limits based on an emissions average should use a different approach for estimating allowable emissions considering allowable emissions under the applicable PCWP NESHAP emission limit.

Provisional Calculated Maximum Emissions  -  Formulas for the provisional maximum emissions calculation (lb/hr) are provided below. The maximum emissions reflect estimates of the highest short term emissions during the calendar year. The maximum short-term emissions are calculated as the annual uncontrolled emissions divided by annual operating hours to approximate maximum lb/hr assuming there is 1 hour when the process is operating but the control device is out of service (e.g., during the PCWP routine control device maintenance exemption).

Pollutants with Available Provisional Calculations for this SCC  -  This column of the spreadsheet lists the pollutants in the set of available provisional calculations for a given SCC. This column is provided for informational purposes. The same information is also provided in the SCC Crosswalk in Appendix 8 which identifies HAP for which provisional calculations are available. Pollutants for which all data used in evaluating emission factors was non-detect are not included in the provisional calculations. It is not necessary to include emission estimates based on measurements that were always below the detection limit. However, if your facility is known to emit a HAP not included in the list of pollutants for which provisional calculations are available, you would need to use another method to estimate emissions for that pollutant.
The HAP metals with provisional calculations include: Antimony, Arsenic, Beryllium, Cadmium, Chromium, Cobalt, Lead, Manganese, Mercury, Nickel, Selenium, Chromium III, Chromium VI, Elemental Gaseous Mercury, Gaseous Divalent Mercury, and Particulate Divalent Mercury. The default chromium and mercury emission factors are speciated using the defaults described previously.
Copying/Pasting Provisional Calculations into the Required Emissions Columns  -  You are not finished with a provisional calculation until you have populated columns M-O!
To complete the use of a provisional calculation, after reviewing the prepopulated data for representativeness and entering the required information, you must copy and paste special as values the calculated actual, allowable, and/or maximum emissions results from columns AF-AH into the corresponding required columns M-O for each pollutant. It is extremely important that you paste the calculated results "as values" so that you do not copy/paste the underlying formulas. Copying the formulas will result in errant values when they are posted.
How do I paste as values?
To paste as values in Excel, select the cells you wish to copy and right click to copy them. Navigate to the destination cells, right click and select "Paste Special" and choose "Values."

c. 	CEMS data (PCWP_CEMS.xlsx)
You are not required to install or operate any new CEMS to respond to this survey. The EPA is requesting existing CEMS data for calendar year 2016 (CY2016) operations from facilities that have installed CEMS on APCD controlling process units currently subject to emission limits or work practices under the PCWP NESHAP. For example, provide CEMS data if you continuously monitor total hydrocarbon (THC) to demonstrate compliance with the 20 ppm limit from the add-on control compliance option 2 in Table 1B to Subpart DDDD of Part 63. You do not need to supply CEMS data for power boilers unless they were installed to show compliance with a PCWP NESHAP emission limit.
CEMS data that are representative of your current operations are requested. Continuously monitored emissions of THC, PM, carbon monoxide (CO), or specific HAPs are of interest. You are not required to supply CEMS data that are no longer representative of the current process unit and control system configuration.
The PCWP_CEMS.xlsx spreadsheet is divided into three tabs to reflect different averaging times. The CEMS tab reflects 1-hour averages while the CEMS3hr and CEMS24hr tabs reflect 3-hour and 24-hour averages. You only need to complete one of the tabs for each CEMS based on the averaging time used at your facility. Each worksheet is designed to accommodate data for one pollutant from one CEMS (including oxygen data, if applicable). If you have multiple pollutants or CEMS (e.g., two CEMS on different process units), then you must make multiple copies of the tab in order to enter data for the additional CEMS.
If providing oxygen correction data, please use the drop-down menu question at the top of column N to indicate whether the pollutant concentrations provided in column N are the O2-corrected concentrations or actual measured concentrations uncorrected by the O2 data provided.
Please use columns N and O to label data averages that were impacted by startup or shutdown conditions, or that would be considered invalid during calibrations, process unit downtime (e.g., periods of zero production, or when the process unit is offline but the CEMS may continue to operate), or for other reasons. This information provides valuable insights into how emissions may change during periods outside of normal operation.
Columns P through R provide optional space for inclusion of data in alternative units of measure should you wish to provide data in a different form.
What if my data are not in a form that can be inserted into the CEMS tab?

   It is very helpful for the EPA's data analysis purposes if data are entered into the CEMS template provided. However, we understand that some CEMS software may not be configured to provide output that can be easily converted to our preferred spreadsheet format. We also understand that, in some cases, the hourly production data requested in the CEMS spreadsheet may not be coupled with the CEMS data or may not be available in a manner to be easily linked to the CEMS data. If you face these or related issues, please note that EPA is not asking you to hand enter hard copy CEMS data into the spreadsheet. You may provide CEMS data in an alternative format if you are unable to convert it to our spreadsheet format within the timeframe for this survey. We ask only that you provide CEMS data in a form suitable for analysis (e.g., spreadsheet or data base format). We will accept more recent CEMS data (e.g., from the most recent 6 months) if 2016 CEMS data are no longer in electronic form due to company records retention policies. Further, you may omit the production data if they cannot reasonably be included in your CEMS spreadsheet. Estimates of production data are acceptable (e.g., if you have a daily production rate, you may divide by 24 operating hours in a day to estimate hourly production).
