What's new for this Emissions Reporting Year

2023 is an 'Air Toxics’ reporting year. Facilities are asked to report Air Toxics in addition to the reporting of Criteria Air Pollutants and Greenhouse Gases which are reported every year. The Air Toxics List can be found here: https://www.pca.state.mn.us/sites/default/files/aq-ei4-32.xlsx.

e-Services Enhancements

  • A data file upload can be used to update data for one or more processes at a time for the Processes & Throughput data and the Process Emissions data. Guidance for using the data file upload can be found in the How to edit "Processes & Throughput” for one or more processes at a time section and in the How to edit “Process Emissions” for one or more processes at a time section.
  • QA/QC enhancements have been added to the Processes & Throughput Details page and to the Process Emissions Details page. The system will alert the user if the value entered for the current inventory year is either greater than twice the amount reported in the previous inventory year or less than half the amount reported in the previous inventory year.
  • A search box/filter has been added to the Add Pollutants page to make finding and selecting pollutants easier.
  • A PFAS review statement has been added to the Submit Emission Inventory page. This review statement will only be displayed for facilities that were identified as likely to use or emit any of the 51 PFAS pollutants listed in the MPCA PFAS Monitoring Plan. The facilities that are being asked to review the PFAS review statement have been notified by the MPCA.
  • ‘Design Capacity’ is now a required field when the emission unit type is one of the following; boiler, turbine, combined cycle (boiler/gas turbine), reciprocating IC engine, or process heater and the emission unit ‘Status’ is ‘Operating’.

Electronic Inventory

Large facility EI types will access Consolidated Emissions Data Repository (CEDR) via the MPCA e-Services Portal and enter data needed for the calculation of emissions. Hard copy forms will not be accepted.

CEDR will calculate emissions prior to submittal to the MPCA, allowing facilities to verify emissions. In addition, CEDR will display unit and fuel type from the previous year, which will ease data entry and verification and make submittal of data more seamless. As time allows, please review and update the non-required data fields in your inventory.

Fields with a red asterisk, "*", are required to be populated for a valid submittal (unless noted otherwise).

Control Equipment percentages directly from the permitting data base that were used in permitting the facility are pre-populated in the system. Some of the data may not be representative of what is actually at the facility. Some facilities will need to update control equipment percentages to be able to calculate emissions correctly.

General Information

Inventory Submittal Required

Under the emission inventory rule, Minn. R. 7019.3000, as the owner or operator of a facility needing an air quality permit, you are required to submit an annual air emission inventory. The Minnesota Pollution Control Agency (MPCA) calculates emissions for the following pollutants: carbon monoxide (CO), nitrogen oxide (NOx), filterable particulate matter (PM), filterable PM smaller than 10 micrometers in diameter (PM10), condensable particulate matter, sulfur dioxide (SO2), lead (Pb), volatile organic compounds (VOCs), ammonia (NH3), and filterable emissions of PM smaller than 2.5 micrometers in diameter (PM2.5). Submission of this information by April 1 of the year following the year being reported is required by Minn. R. 7019.3000, and Minn. Stat. § 116.091, subd. 1 and 116.07, subd. 9. If your facility does not submit an emission inventory on time, your facility may be subjected to an enforcement action and your next annual air fee will not be calculated using actual emissions, but rather using Minn. R. 7002.0025, subp. 3.

The MPCA uses the information you provide in this inventory to quantify emissions and calculate your annual Air Emission Fee. The fee rule, Minn. R. 7002.0015 to 7002.0085, gives the MPCA the authority to charge fees for air emissions.

Emission Calculation Hierarchy

Emissions must be calculated using the following hierarchy:

  1. Continuous emissions monitoring (CEM) data from reporting year.
  2. Stack test data may not be more than ten years older than the last date of the emission inventory period (example: a stack test performed between January 1, 2014 and December 31, 2023 can be used to report 2023 emissions data)
  3. VOC material balance and SO2 material balance. The calculations will only be accepted if they are based on the procedures listed in Minn. R. 7019.

If a facility cannot use the above methods for calculating their facility's actual emissions, default emission factors will be used.

Reporting Instructions

Notice: Before entering data

Only one person should work on the Emission Inventory (EI) at any point in time. If more than one person is editing the inventory, the system will only save the latest edits.

For all facilities

  1. The Emission Inventory is to be completed when your facility's processes are finished for the calendar year.
  2. Each field identified with an asterisk (*) must be filled out where applicable or the emission inventory is considered incomplete. Each page must be completed and saved.
  3. Please review the current data in the system and make changes/updates. Much of the information will only have to be updated when changes are made to the facility, including Contact Information, and Processes.
  4. If your facility did not operate in the current reporting year, you must still complete the inventory including entering zeros for throughputs and hours operated.
  5. All emission sources with the exception of insignificant activities identified in the air permit should be included in the emission inventory. Insignificant activities are defined in Minn. R. 7007.1300. Accidental discharges and releases of ammonia from pressurized tanks should be quantified and reported on the inventory.
  6. All fugitive emissions, with the exception of fugitive emissions resulting from insignificant activities, should be reported in the emission inventory.
  7. If your facility has emissions not included in normal calculations, including control equipment breakdown, report the uncontrolled emissions per unit/process by adding a Process in the Process & Throughput page and calculating the emissions on the Process Emissions page.
  8. To align control equipment data with those used in permitting, control equipment control and capture efficiencies shown reflect current permitting data base numbers, rather than generic default control percentages previously used in emission inventory calculations and summary sheets. Facilities can only take credit for the operation of air pollution control equipment if such equipment is required under the conditions of a current permit or an applicable rule (e.g., NSPS, MN Pollution Control Equipment Rule) (see Minn. R. 7019.3020(G)).

Pollutant Specific Guidance

Particulates

Particulates are separated into Filterable (PM-FIL, PM10-FIL, PM25-FIL) and Total Condensable (PM-CON) fractions. If your facility has performed a performance test on particulates please separate. Performance test Method 5 identifies filterable, which is equal to PM-FIL and PM10-FIL. Method 202 identifies total (filterable + total condensable). Subtract the filterable portion from the 202 total to get the total condensable.

Performance Test Example: Method 5 has a 5.50 lb/hr filterable emission factor, Method 202 has a 7.25 lb/hr total emission factor. The PM-FIL and PM10-FIL emission factor is 5.50 lb/hr. The PM-CON emission factor (7.25 – 5.50 = 1.75) is 1.75 lb/hr.

Greenhouse Gases

Facilities holding a Capped Permit are required to report GHG emissions in order to comply with the requirements of Minn. R. 7007.1146 subpart 2, item E. Facilities holding a Title V permit are required to report GHG emissions to the MPCA under the Minn. Statute 216H.021 Subd. 2. (b) (1).

The MPCA’s electronic reporting system will automatically calculate GHG combustion emissions for all large EI type facilities. The MPCA will calculate emissions for carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4) using emission factors from title 40, part 98, EPA Mandatory Reporting Rule. Facilities will have the ability to review and edit the combustion emissions data with site specific information if available. Additionally, facilities will also be able to report non-combustion GHG emissions (if applicable) through the MPCA e-Services electronic reporting website.

The MPCA has added about one hundred additional fluorinated greenhouse gases (F-GHGs) and fluorinated heat transfer fluids (F-HTFs) to the list of available GHGs for reporting. For more details and to see the list of newly added GHGs, their CAS numbers and Global Warming Potentials (GWPs) please check the emissions reporting website.

Mercury

Reporting requirements for Emission inventory rule, Minn. R. 7019.3000 subp.3

In 2014, the emissions inventory rule was amended to adopt new rules relating to mercury air emissions reporting; Minn. R. 7019.3000 subp.3. The rule requires facilities with actual mercury emissions of three pounds per year or more to submit an annual mercury emissions inventory to the MPCA.

Below are some answers to common questions regarding this new rule language.

Does my facility need to report mercury emissions?

  • If your facility exceeds three pounds of mercury emissions per year after controls you must report mercury emissions every year beginning with the 2015 inventory year.
  • If your facility has less than three pounds of mercury emissions per year after controls you must report mercury emissions every three years beginning with the 2017 inventory year.

Mercury Emissions Consumer Information Act, Minn. Stat. & 116.925

Electric utilities that produce electricity in Minnesota are required to report mercury emissions annually for the Mercury Emissions Consumer Information Act, Minn. Stat. & 116.925. To report mercury emissions select “add new pollutants” and select “Mercury” on the “Process Emissions” page on the e-Services electronic reporting website. Give all required information and include Megawatts in the comment section.

Air Toxics

There are 204 individual air toxic (AT) chemicals and 830 chemicals within 29 groups included in the air toxics emission inventory. This list includes the 188 hazardous air pollutants (HAPs) identified by the Environmental Protection Agency (EPA) and other individual pollutants that are part of HAP groups, pollutants in the Great Lakes regional air toxics emission inventory project, and pollutants of concern in Minnesota’s outdoor air. The list also includes 428 new per- and polyfluoroalkyl substances (PFAS). The MPCA collects data on air toxics emissions every three years. The 2023 reporting year is an air toxics reporting year. The MPCA does not charge fees for air toxics. The Air Toxics List can be found here: https://www.pca.state.mn.us/sites/default/files/aq-ei4-32.xlsx..

2023 Air Toxics updates

  • EPA added 1-bromopropane CAS No. 106-94-5 (also known as 1-BP, n-propyl bromide, and nPB) to the list of Hazardous Air Pollutants (HAPs).
  • EPA added a number of individual pollutants classified under the Polycyclic Organic Matter (POM) group. These pollutants were added to be consistent with all TRI listed chemicals and are shown on the air toxic pollutants list.
  • EPA also added individual isomers of Lindane. In the past emissions from Lindane were only reportable under “Lindane (All isomers).” All isomers of Lindane are shown on the air toxic pollutants list.
  • EPA added salts and esters of 2,4-D (2,4-Dichlorophenoxy Acetic Acid (2,4-D)). All salts and esters of 2,4-D are shown on the air toxic pollutants list.
  • MPCA added Chlorine Dioxide and Sulfuryl Fluoride to the list of reportable pollutants to be consistent with the EPA pollutant list.
  • MPCA added new PFAS pollutants to the air toxic pollutants list.
  • MPCA added some pollutants to the list of reportable pollutants because of potential inhalation risk.


If your facility is required to keep records of HAP emissions as a condition of its permit, then you should submit HAP emission data. If your facility is not required to keep HAP emission records, then you are strongly encouraged to join the majority of individual air permit holders and submit air toxics emission data voluntarily.

All facilities with individual air permits are included in the ATEI, even if the facility does not submit data. MPCA staff will estimate air toxics emissions for facilities not required to submit air toxics data using any of the following:

  • Emission Factors from AP-42 or Factor Information REtrieval (FIRE) Data System
  • Data from the Toxic Release Inventory (TRI) database
  • Information in air permits and air permit applications
  • Information in other documents
  • MPCA staff judgment

Directly reported emissions data from facilities is preferred over MPCA staff estimates. Using data submitted by facilities results in a more reliable emission inventory.

For boilers, heaters, and internal combustion engines, it is not necessary to report air toxics emissions if your facility does not have process-specific emission factors calculated from performance test results. The MPCA can estimate air toxic emissions from combustion processes for you by using the most current emission factors in the EPA’s FIRE database and your fuel usage data reported to the MPCA for the this year’s air toxics emission inventory (ATEI). Process-specific fuel heating values, however, can be used to derive more accurate estimates.

If you are among the majority of air permit holders that provide data for the ATEI, the MPCA thanks you and your organization for contributing to a higher quality emission inventory that is increasingly relied on for a wide variety of purposes. If you have not submitted an inventory in the past, please consider making this your first year.

To report Air Toxics emissions from permitted units, facilities will be able to add air toxic pollutants on the "Process Emissions" page.

Material Balance Calculations Use the maximum of the composition range when calculating air toxics using a material balance approach. To report Air Toxics emissions from non-permitted units, facilities will have to add emissions information under the Emission Unit 000 "(EU000) Non-Permitted Emissions for AT and GHG" on the "Process Emissions" page.

Recommendations for reporting data for specific groups of compounds

Recommendations for reporting data for specific groups of compounds are summarized below in a hierarchy of the most preferred method to the least preferred method. For pollutant groups, only one reporting strategy per group per process should be used. Simultaneous use of more than one reporting strategy (e.g., reporting both individual chromium compounds and total chromium for the same source) will result in double counting.

Metal and cyanide groups:

  1. Within a process, and for a given metal or cyanide group, separately report emissions of all individual metal or cyanide compounds [e.g., report emissions of arsenic trioxide (ARSENIC 03, CAS No. 1327-53-3) if the process only has one compound in a metal/cyanide group and it can be reported under that compound]. Do not report it under the group [e.g., arsenic (ARSENIC CAS No. 7440-38-2)]. All individual compounds should be reported as the mass of the total compounds, not just the metal within the compound.
  2. Report only emissions of metal or cyanide within the compound. To estimate the amount of metal in a compound divide the mass of the metal in 1 mole of the compound by the compound's molar mass and multiply the result by 100. For example if you have 1 lb emissions of ARSENIC O3 CAS No. 127-53-3 and you wish to report only ARSENIC CAS No. 7440-38-2, (molar mass of ARSENIC is 149.84, and molar mass of ARSENIC O3 is 197.841 g/mole, therefore ARSENIC is (149.84/197.841)*100 = 75.74% of the compound. If you are emitting 1 lb of ARSENIC O3, the amount of ARSENIC reported would be 0.7574 lbs. Use PubMed (nih.gov) to determine the mass of a compound.
    • Chromium - Since there is widely varying toxicity, you need to separate chromium compounds into trivalent (CHROMIUM III, CAS No. 16065-83-1) and hexavalent chromium (CHROMIUM VI, CAS No. 18540-29-9) if possible. You may report emissions for CHROMIUM, CAS No. 7440-47-3 if you cannot separate emissions. If the emissions are reported for CHROMIUM, CAS No. 7440-47-3 the emissions will be allocated to CHROMIUM III and CHROMIUM VI based on generic information when the data are used.
    • Do not include metals or cyanide already reported using the more preferred method in number 1. For example, CHROMIUM III, CAS No. 16065-83-1 and CHROMIUM CAS No. 7440-47-3 cannot be reported under the same process. The e-Services website will give an error message if both are reported.

Dioxins/furans:

Report mass emissions of the following 17 individual congeners of chlorinated dibenzodioxins (CDDs) and chlorinated dibenzofurans (CDFs):
Pollutant code Short Description Cas No.
HPCDD1234678 1,2,3,4,6,7,8- HEPTACHLORODIBENZODIOXIN 35822-46-9

TCDF,2378 2,3,7,8-TETRACHLORODIBENZOFURAN 51207-31-9

Glycol ethers:

  1. Report emissions for individual glycol ethers. All individual glycol ethers are shown on the air toxics pollutant list. EPA uses the Toxics Release Inventory (TRI) List of Toxic Chemicals within the Glycol Ethers Category to determine if a chemical falls into a glycol ether category. If the chemical is not listed in Table 1 of the above guidance please use the structural definition provided by EPA to determine if the chemical is a glycol ether. The definition is:
R - (OCH2CH2)n - OR' where
n = 1, 2 or 3
R = alkyl C7 or less; or R = phenyl or alkyl substituted phenyl;
R' = H or alkyl C7 or less; or OR' consisting of carboxylic acid ester, sulfate, phosphate, nitrate, or sulfonate.
  1. If you cannot report individual glycol ether emissions, report total emissions of glycol ethers as a group under pollutant code GLYCOL ETHRS. You should not report emissions of one pollutant under both the individual pollutant name and GLYCOL ETHRS. The e-services website will give an error message if both are reported.


Xylenes and cresols:

  1. Report emissions for individual xylene and cresol isomers. If you report emissions for individual isomers do not report any emissions for total xylenes (XYLENES ISO, CAS No. 1330-20-7) or total cresols (CRESOLS MX IS, CAS No. 1319-77-3) to avoid double counting.
  2. If you cannot report individual emissions of xylenes or cresols, report total emissions of xylenes or cresols as a group under XYLENES ISO, CAS No. 1330-20-7 or CRESOLS MX IS, CAS No. 1319-77-3.


Polycylic organic matter (POM):

Report emissions of as many individual POM compounds as possible. All POMs are shown on the air toxic pollutants list. If you cannot report individual emissions of POM, report total emissions of POM.

Lindane

  1. Report emissions for individual lindane isomers. If you report emissions for individual isomers do not report any emissions for total Lindane (LINDANE ISO CAS No. 58-89-9) to avoid double counting.
  2. If you cannot report individual emissions of Lindane, report total emissions of Lindane as a group under (LINDANE ISO CAS No. 58-89-9).


Per- and Polyfluoroalkyl substances (PFAS)

For the 2023 emissions inventory year, MPCA added 428 PFAS pollutants to the list of reportable pollutants. As part of the PFAS Monitoring Plan, MPCA is asking approximately 160 facilities to report air emissions of 51 PFAS pollutants for the 2023 reporting year. These 51 PFAS pollutants can be identified in the air toxic pollutants list by filtering the ‘Notes for Group’ column for ‘PFAS Monitoring Plan, OTM-45’.

PFAS reporting expectations and references were emailed to the 160 affected facilities in December 2022. A recording of the MPCA’s November 2022 PFAS presentation can be found on the MPCA’s YouTube channel. The presentation includes ways to identify possible sources of PFAS emissions and estimate the emissions. MPCA’s PFAS industrial uses search tool (catalog) on its PFAS studies and reports page. For assistance identifying PFAS compounds in the materials you use, refer to the Air Emissions Reporting - PFAS Compound Identification fact sheet.

The OTM-45 pollutants and several hundred additional PFAS pollutants will be available in e-Services for any Large or Registration Option D facility to report 2023 emissions. This includes all salts and ions of OTM-45 analytes and all PFAS compounds EPA included in the Emissions Inventory System (EIS) and Toxics Release Inventory (TRI).

PFAS compounds can be identified in the air toxic pollutants list by filtering the ‘Pollutant Group’ column for ‘PFAS’.

There is no ‘PFAS’ pollutant group under which multiple PFAS can be reported for 2023. If you have individual PFAS compounds to report that are not in the air toxic pollutants list, please contact us.

For questions about PFAS reporting, or if you would like to be included on the PFAS air emissions email list, contact Joe Miller at joseph.j.miller@state.mn.us or call 651-757-2570.

How to edit "Processes & Throughput" for a single process

  1. Select "Processes & Throughput" on the “Select Task” page.
  2. The system will display a data grid view of the "Processes."
  3. Select a "Process ID."
  4. The system will display an editable form view of selected "Process ID."
  5. Edit data and select:
    • "<< Previous Process": Save data and go to previous process.
    • "Next Process >>": Save data and go to the next process.
    • “Save” Save data and go back to the grid view(2).
    • “Cancel” Undo any changes and go back to the grid view.
  6. The system will validate data before saving.

Notes:

  • If the throughput unit is not the appropriate throughput unit for a particular throughput, please enter 0.00 for the throughput, go to the ‘Process Emissions Details’ page, change the emission calculation method to ‘Other’, select the throughput units you wish to use, and enter the throughput value.
  • SCCs identified as “99999999” are used with new emission units that have not yet had emissions calculated (for example, new units/processes from a new permit action). An SCC of ‘99999999’ is not valid if emissions should be calculated from this new process. Please use the list generated by clicking on “Source Classification Code” as guidance to select the correct SCC.
  • For existing emission units that are part of a group in which the activity from all units is aggregated and assigned to a different emission unit within the group, a valid SCC code must be selected and a site specific emission factor of zero must be identified in the “Process Emissions Details” page. This will ensure that emissions are only calculated for one unit within the group.

Control Equipment (Submitter and Preparers)

Field Name Description
Control Equipment ID This is a combination of a 2 digit letter code, 'CE' and a 3 digit number (001, 002, 003...) that is assigned to each control equipment.
Type The control equipment type code and control equipment description for the related control equipment ID.
Start Date The date on which the identifier became effective. Format of Date = 'mm/dd/yyyy'. (For example start date of emission unit)
End Date The date on which the identifier is no longer applicable. Format of Date = 'mm/dd/yyyy'. (For example date when emission unit was physically removed)
Pollutants Controlled Identifies the pollutants reduced by the control equipment. (Ammonia, CO, Lead, NOx, PM-FIL, PM-CON, PM10-FIL, SO2, VOC)
Capture Efficiency (%) The capture efficiency is the portion of the pollutants emitted that are routed via ducting to the control equipment (e.g., a fabric filter). Capture Efficiency will be within a range of 0-100%. (Total enclosure will be 100%)
Control Efficiency (%) The control efficiency is the portion of the pollutant that retained in the control equipment or is destroyed by the control equipment. Control Efficiency will be within a range of 0-99.999%.

Revising Control Equipment, Capture and Control Efficiency Information:

Control Equipment percentages directly from the permitting data base are used. Some of the data may not be representative of what is actually at the facility. Facilities must update and add additional control equipment percentages per permit to be able to calculate emissions correctly.

For the purposes of the EI, you can only take credit for the operation of air pollution control equipment if such equipment is required under the conditions of a current permit or an applicable rule (e.g., NSPS, MN Pollution Control Equipment Rule) (see Minn. R. 7019.3020(G)). For any specific control device where you wish to revise the information, please provide a reference to either the location on the permit where the operation of the control is required or to the specific rule that requires its operation.

For revising or adding capture or control efficiency values, the proposed efficiency should be based on one of the following:

  • Stack test data (provide a reference to the MPCA approval).
  • Permit efficiency limit (provide reference as to where to find it in the permit) or
  • Rule limit (provide rule citation where efficiency can be found).

If your permit requires the operation of a specific control device but does not include a specific capture or control efficiency for a given pollutant (e.g., permit includes an efficiency for PM but not PM10, permit includes an emissions limit but not a control efficiency limit, etc.), you may propose a value for the purposes of the EI. You must include supporting information to justify your proposal. Some possible references for a proposal might be an applicable efficiency from Minn. R. 7011.0070, EPA guidance documents, control equipment manufacturer guarantees, etc. Keep in mind that any proposed value may later be reviewed by the MPCA and incorporated into your permit as a limit with corresponding testing and monitoring requirements.

For any facility the capture efficiency can only be:

  • A capture efficiency from an MPCA-approved performance test.
  • Any specific capture efficiency listed as a permit requirement (as discussed above).
  • 100%, if the device meets the definition in Minn. R. 7011.0060 for a total enclosure; or
  • 80% for any hood that is certified under Minn. R. 7011.0072.

  2. The system will display a data grid view of "Emissions."
  3. Select a "Process ID" to edit (for example “EU001/PD001”).
  4. The system will display an editable data grid view of "Pollutants."
  5. Select pollutant group wanted in “Filter by” drop down selection.
  6. Edit data and select buttons:
    • "<< Prev Process": Save data and go to previous emissions process
    • "Next Process >>": Save data and go to next emissions process
    • "Add New Pollutants": Add pollutants that are not calculated on screen, if an SCC does not have a default factor pollutants will not show
    • "Save & Close": Save data and go back to the grid view (2)
    • "Cancel": Undo any changes and go back to the grid view (2)
  7. The system will validate data before saving.

Notes:

  • The system may update selections and emissions automatically. Please check emission values.
  • If Throughput Amount and Emission Factors are present (remember zero is valid emission factor) the system will calculate emissions. Please check emission values.
  • Particulates are separated into Filterable (PM-FIL, PM10-FIL, PM25-FIL) and Total Condensable (PM-CON) fractions. If your facility has performed a performance test on particulates please separate. Performance test Method 5 identifies filterable, which is equal to PM-FIL and PM10-FIL. Method 202 identifies total (filterable + total condensable). Subtract the filterable portion from the 202 total to get the total condensable.
  • Performance Test Example: Method 5 has a 5.50 lb/hr filterable emission factor, Method 202 has a 7.25 lb/hr total emission factor. The PM-FIL and PM10-FIL emission factor is 5.50 lb/hr. The PM-CON emission factor (7.25 – 5.50 = 1.75) is 1.75 lb/hr.
  • GHG emissions will be calculated per process by the CEDR system if site specific information was not given.
  • CO2 biogenic emissions are calculated and identified as CO2-B.
  • If using an emission calculation method that does not use an emission factor (for example CEM, Material Balance or Engineering Judgment) the user must blank out/delete/null the emission factor to prevent the System from calculating emissions.
  • If using the TANKS program to calculate emissions, please select “Engineering Judgment” as Emission Calculation Method. Note: The TANKS Emissions Estimation Software, Version 4.09d is no longer supported by EPA. We suggest following the guidance in AP-42 Chapter 7 for estimating VOC emissions from tanks.
  • The “Filter by” dropdown list above the grid will default to “Criteria Air Pollutants’ the first time that you enter the “Process Emissions Details” page from the “Process Emissions” page. After you have accessed the “Process Emissions Details’ page once, every time that you return to this page it will default to the pollutant group that was last selected. If you enter the “Process Emissions Details” page from the “Add New Pollutants” page than the “Filter by” dropdown list will default to the pollutant group that was selected in the “Add New Pollutants” page.

Guidance on using the MPCA’s e-Services data file upload

General Guidelines for updating Processes Emissions data with the file upload

  • New emission units and processes cannot be added on import and will be ignored/not added to draft submittal in e-Services
  • Rows deleted from the import file will be ignored/not removed from the draft submittal in e-Services
  • New pollutants can be added to existing processes
  • Changes made to the ‘Unit ID’, ‘Subject Item’, ‘Process ID’, and ‘Source Classification Code’ do not get updated on file import and will be ignored/not added to draft submittal in e-Services.
  • Emissions that use an emission factor will be automatically calculated in e-Services upon file import, but a value must be present in the ‘Total Emissions (TON)’ column for all pollutants when importing. If the ‘Total Emissions’ value entered in the import file for a pollutant calculated with an emission factor is incorrect, it will be corrected upon file upload.
  • An emission factor with Emissions Calculation Method ‘USEPA Emission Factor’ or ‘S/L/T Emission Factor’ cannot be edited using the file upload.
  • The validation error; ‘Emissions throughput amounts are inconsistent for process EUXXX/PDXXX between pollutants POLLUTANT,X and POLLUTANT,Y to correct error, navigate to page ‘Process Emissions’ and click Save.’ cannot be fixed with the file upload. This error should be corrected clicking ‘Save’ on the ‘Process Emissions’ page in the user interface AFTER all data file uploads are completed. The error may reappear if another data file upload is performed after the errors are fixed.


Updating 'Process Emissions' data with the file upload

  1. Click on the 'Download Review Workbook' button to download a file with the Process Emissions data for all processes.
  2. Save a copy of the downloaded file.
  3. Delete all worksheets in the copied file except for the 'Facility' and 'Emissions' worksheets.
  4. Unprotect the 'Emissions' worksheet. (In Excel, go to 'Review', select 'Unprotect Sheet')
  5. Make any needed revisions on the 'Emissions' worksheet and save the file. (Note: New units and processes cannot be added by file import)

Required Fields on the ‘Processes’ worksheet:

Key:

∗ - Required field

1 - Emission Factor requirement is contingent on ‘Emissions Calculation Method’ (Continuous Emission Monitoring, Material Balance and Engineering Judgement may have a null emission factor).

2 - System automatically converts fuel throughputs to heat (E6BTU) to use default emission factors which are in (LB/E6BTU). Automatic conversion uses the heat content provided by facility first, if no heat content is provided, a default heat content is used.

3 - Stack test date is required in the 'Stack Testing Date and Emission Factor Comment' field when the ‘Emissions Calculation Method’ is 'Stack Test'.

∗ Pollutant
∗ Emissions Calculation Method
∗ Throughput Material
∗ Throughput Amount

How to “Add New Pollutants”

From the “Process Emissions Details” page

  1. Select “Add New Pollutants.”
  2. The system will display a grid view of "Pollutant Codes" listed in alphabetical order.
    Note: The “Filter by” dropdown list above the grid will default to the pollutant group that was selected on the “Process Emissions Details” page.
  3. Choose the “Pollutant Codes” to display in the grid by selecting one of the pollutant groups: “Criteria Air Pollutants”, “Air Toxics”, or "Greenhouse Gases” listed in the “Filter by” dropdown list.
  4. The system will display all of the pollutant codes for the selected pollutant group provided that the pollutants do not already appear on the “Process Emissions Details” page.
  5. Select the check box next to the pollutant(s) that you wish to add to the pollutants displayed on the “Process Emissions Details” page.
  6. Select “Continue” after you have finished selecting pollutants.
Note: You can only add pollutants from one pollutant group at a time. If you wish to add pollutants from multiple pollutant groups you must repeat steps 1-6 until you have added all of the pollutants that you wish to add.

Process Emissions instructions if using site specific calculations other than default AP-42/WebFIRE emission factors.

  • DO NOT DELETE pollutants, if the pollutant should be identified as zero emissions please identify a site specific factor by selecting ‘Other’ as the calculation method and entering a 0.00 emission factor. If the pollutant is deleted, it will be calculated again with a default emission factor based in the SCC code.
  • If your facility uses CEM data, performance test data (CO, NOx, PM-FIL, PM10-FIL, PM-CON, SO2, Pb, VOCs), mass balance (SO2 and VOCs), permit limits, control equipment breakdown or other, alternative methods of emission calculation please identify on the Process Emissions task/tab. This site specific information must be given every year.
  • To record the results of stack tests, CEM data, VOC or SO2 material balance calculations, permit limits or other, alternative methods of emission calculation, read the appropriate parts of the 'Instructions For Reporting CEM, Stack Test, VOC or SO2 Material Balance Results' identified below in the next header. If a CEM or a stack test generated data for a number of different raw materials, the annual test data or annual CEM data should be apportioned to each type of raw material.
  • The emission inventory rule requires a facility to use continuous emission monitoring (CEM) data on the annual emission inventory if it's available.
  • You must use the results from a stack test if the test was performed in accordance to our performance test rules and if there is no CEM data available for that unit. Please include date of the test ('mm/dd/yyyy' in the Stack Test comment field), the test result itself and the emission calculations on the Process Emissions task/tab. If a unit was tested for the same pollutant(s) more than once in the past inventory year, please contact an Emission Inventory Coordinator and ask how to apply these stack test results.
  • Particulates are separated into Filterable (PM-FIL, PM10-FIL, PM25-FIL) and Total Condensable (PM-CON) fractions. If your facility has performed a performance test on particulates please separate. Performance test Method 5 identifies filterable, which is equal to PM-FIL and PM10-FIL. Method 202 identifies total (filterable + total condensable). Subtract the filterable portion from the 202 total to get the total condensable.
  • Performance Test Example: Method 5 has a 5.50 lb/hr filterable emission factor, Method 202 has a 7.25 lb/hr total emission factor. The PM-FIL and PM10-FIL emission factor is 5.50 lb/hr. The PM-CON emission factor (7.25 – 5.50 = 1.75) is 1.75 lb/hr.
  • GHG emissions will be calculated per process by the CEDR system, if site specific information was not given.
  • CO2 biogenic emissions are calculated and identified as CO2-B
  • If you calculate VOC emissions using a VOC material balance, please note that the VOC content and the density (if used in the calculation) must come directly from the product Safety Data Sheet (SDS). Estimations of VOC contents and densities are unacceptable. Additionally, include a sample calculation with the inventory as an attachment. Please note that MPCA staff may request the full calculation for all material balances.
  • If your facility uses AP-42 or WebFIRE emissions factors other than the default factors associated with the Source Classification Code (SCC) shown, please identify on the Process Emissions task/tab and reference the chapter and page number of the emission factor in the Stack Testing and Emission Factor comments column.
  • U.S. Environmental Protection Agency has changed the classification and reporting requirements for t-Butyl Acetate (tertiary butyl acetate or TBAC). TBAC is subject to the same requirements as Volatile Organic Compounds (VOCs) when reporting annual VOC emissions, except TBAC must be reported separately from other VOCs. Calculate all TBAC emissions and list them separately from VOC emissions. Attach TBAC emissions as a supplemental file to the emission inventory. For more information please see the TBAC factsheet on the MPCA website https://www.pca.state.mn.us/sites/default/files/aq7-01.pdf

Instructions for Reporting CEM, Stack Test, VOC or SO2 Material Balance Results

Listed below are directions for several types of estimation methods allowed under the inventory rule. Please read the applicable sections thoroughly for each section.

Continuous Emissions Monitoring

Minn. R. 7019.3040 requires facilities with CEMs to use CEM data on the inventory.

On the “Process Emissions” task/tab – Process Emissions Details:

  1. Identify the Emission Calculation Method as ‘Continuous Emission Monitoring System.'
  2. Change the ‘Throughput Units’ from the drop down choices, if needed. Please note the emission factor units will update automatically.
  3. Update the Throughput Amount if needed.
  4. It is suggested to leave the emission factor blank in the Emission Factor column; if an emission factor is present the system will calculate emissions.
  5. Enter the emissions you calculated in the Total Emissions (Tons) column.
  6. Click ‘Save’ button (System will check for validation and return you to the Process ID list, ‘Process Emissions’ page). If errors, fix and click ‘Save’ again).
  7. Click on Process ID that was just updated to make sure it saved in the Process Emissions Details page.

Include the calculations showing how the emissions were calculated from the CEM data as an attachment to the emission inventory submittal. If multiple fuels or raw materials were used during the CEM operation, apportion the annual calculated emissions per process among each type of fuel or raw material. If the CEM was down for any period of time, the emissions for that time period must be calculated by one of the following methods: stack test data as specified in the inventory rule, EPA AP-42 emission factors, enforceable permit limitation, or the method of reporting CEM downtime specified by the US EPA in rules adopted under section 412 of the federal Clean Air Act Amendments of 1990, Public Law Number 101-549, Statutes at Large, volume 104. Please include a discussion and calculation of your down time estimates with the sample calculation on the inventory as an Attachment.

Stack Test

In the absence of CEM data, Stack test data from any test performed in the past 10 years that is in accordance with the performance test rules must be used before any other method of emission calculation. Please use Minn. R. 7019.3050 as guidance.

On the “Process Emissions” task/tab – Process Emissions Details:

  1. Identify The Emission Calculation Method as ‘Stack Test.’
  2. Change the ‘Throughput Units’ from the drop down choices, if needed. Please note the emission factor units will update automatically.
  3. Update the Throughput Amount if needed.
  4. Update Emission Factor if needed.
  5. Enter ‘Stack Test’ date ('mm/dd/yyyy') in the Stack Testing Date and Emission Factor Comment column.
  6. Click ‘Save’ button (System will check for validation and return you to the Process ID list, ‘Process Emissions’ page). If errors, fix and click ‘Save’ again.
  7. Click on Process ID that was just updated to make sure it saved in the Process Emissions Details page.

Include the calculations showing how the emissions were calculated from the test data as an Attachment to the emission inventory. If multiple fuels or raw materials were used during a stack test, apportion the total estimated emissions from the test among each type of fuel or raw material. If a unit was tested for the same pollutant(s) more than once in the past inventory year, please contact an Emissions Inventory Coordinator and ask how to apply these stack test results to the inventory.

If your facility has performed a performance test on particulates please separate. Performance test Method 5 identifies filterable, which is equal to PM-FIL and PM10-FIL. Method 202 identifies total (filterable + total condensable). Subtract the filterable portion from the 202 total to get the total condensable.

Performance Test Example: Method 5 has a 5.50 lb/hr filterable emission factor, Method 202 has a 7.25 lb/hr total emission factor. The PM-FIL and PM10-FIL emission factor is 5.50 lb/hr. The PM-CON emission factor (7.25 – 5.50 = 1.75) is 1.75 lb/hr.

Material Balance

For rules governing the use of VOC Material Balance on the Emission Inventory please use Minn R. 7019.3060 as guidance. Include a sample calculation with the inventory report as an attachment to the emission inventory.

  2. Do I have to calculate my emissions even if I don’t have site specific data to report such as a stack test or a mass balance?
    • No. CEDR will calculate your emissions based on the standard emission factors for the assigned SCC. However, it is highly suggested to review emission calculated before submittal
  3. I changed the pre-populated data and just want to “start over.” How do I restore the data that was originally populated in my facility’s online emission Inventory Reporting account?
    • From the "Air Emission Inventory - CEDR" page select "Delete Draft Submittal" from the "Manage Emission Inventory Submittals" menu. Select the facility that you wish to restore to the originally populated data and click on "Delete".
  4. How do I know which data fields I need to update?
    • Fields designated as required (red*) must be updated if the information in the field is inaccurate and populated if the field is blank (unless otherwise noted). You will need to update the data provided in previous inventories that changes from year to year such as throughput, hours of operation, etc.
    • If any of the following uneditable data have changed, your permit must be revised to reflect such changes: facility name, ownership or control of the facility, or any other facility contact information listed in the permit (e.g., mailing address). You must submit an application to the MPCA to change your permit. You can find the various permit application forms on the MPCA’s Web site at: http://www.pca.state.mn.us/changeforms.
  5. Why are stacks and control equipment tied to all of the processes of an emission unit instead of the unit itself? Is this redundant?
    • All control equipment capture efficiency and control efficiencies are taken directly from the database used by MPCA staff to permit your facility rather than generic default values. The default values may have misrepresented the efficiency values either positively or negatively for your facility in the past. These control efficiencies have been reviewed by MPCA staff during the permitting process and should better reflect control efficiencies of your equipment. These values will be able to be changed if better data is available (e.g. a performance test with both inlet and outlet emission rates), or if a pollutant is not identified as controlled and it should be. For example, if a PM filterable control efficiency is identified and a PM10 filterable efficiency is not identified, you may list a PM10 filterable efficiency and provide supporting rationale/ documentation. See the Help File section titled “Revising Control Equipment, Capture and Control Efficiency Information” for additional instructions.
  6. Can facilities use GHG emissions factors other than the ones used by the MPCA?
    • To calculate GHG combustion emissions MPCA is using generic emission factors from the EPA’s Mandatory Reporting Rule (MRR). The MPCA strives to be as consistent with the EPA as possible. If facilities have site specific emission factors, or want to use emission factors provided by a trade association or similar, they may change the factors provided in the CEDR application.

Inventory Report Submittal:

  1. If I notice an error in my emission inventory that I just submitted, what should I do? Resubmit or notify an EI staff?
    • The Submitter may submit the EI more than once, if necessary, until the EI submittal deadline. To minimize confusion for all involved, please ensure that your first EI submittal will be your best submittal. This intent adheres to the definition of the ‘legal certification’ in the signature block that the Submitter agrees to at the point of the EI submittal.
  2. Do I need to attach any files for the EI submittal to be valid?
    • Which attachments to include with the EI remains the same as the previous EI submittals. Attachments are documentation that adds value and/or clarity to the EI emission estimation methods, e.g. a pdf of the executive summary of performance (stack) tests, a VOC material balance spreadsheet.
  3. The inventory is due and I just hired a consultant to do my inventory submittal. How can I get an extension?
    • Extensions are not allowed. Please submit as soon as possible, or your next year's air fee will be calculated using Minn. R. 7002.0025, subp. 3.
  4. Since the system just calculated my annual emissions, couldn't it also calculate my annual air emission fee?
    • No, because the emissions calculated at the point of EI submittal are draft and are subject to change pending review by the MPCA EI staff.

Glossary of Terms

CROMERR: The Cross-Media Electronic Reporting Regulation (CROMERR) provides the legal framework for electronic reporting (ER) under all of the Environmental Protection Agency's (EPA) environmental regulations. CROMERR applies to: (a) regulated entities that submit reports and other documents to EPA under Title 40 of the Code of Federal Regulations, and (b) states, tribes, and local governments that are authorized to administer EPA programs under Title 40. CROMERR establishes standards for information systems that receive reports and other documents electronically (including email, but excluding disks, CD's, and other magnetic and optical media) that are submitted to satisfy requirements of a program that a state, tribe, or local government is authorized to administer under Title 40. These standards cover a variety of system functions, such as electronic signature validation. The standards are designed to provide electronic submittals with the same level of legal dependability as the corresponding paper submittals. Although CROMERR does not subject EPA systems to the standards, EPA has decided that all of its systems will conform to the standards when they operate to receive electronic submittals that are covered by the regulation.

Copy of Record: The copy of record is defined by the EPA as the document "that is submitted in lieu of paper to satisfy requirements under an authorized program. For such submissions, the copy of record is intended to serve as the electronic surrogate for what we refer to as the "original" of the document received where we are doing business on paper. The copy of record is meant to provide an authoritative answer to the question of what was actually submitted and, as applicable, what was signed and certified to in the particular case.

Electronic Signature: This means any information in digital form that is included in or logically associated with an electronic document for the purpose of expressing the same meaning and intention as would a handwritten signature if affixed to an equivalent paper document with the same reference to the same content. The electronic document bears or has on it a digital (or electronic) signature where it includes or has logically associated with it such information. For MPCA-CROMERR, the electronic signature is comprised of an account's password and one of the five challenge questions that are part of the account creation process.

Submittal Agreement: This means an electronic signature agreement signed by an individual with a handwritten signature. This agreement must be stored until five years after the associated electronic signature device has been deactivated. Note: The full name of the form is ‘Electronic Submittal Agreement for Air Emissions Inventory Report and Submitter Registration Form’. It is referred to throughout this document as the 'Submittal Agreement'.
