Potential to Emit

Forms: GI-07-R/GI-07

Note: If you are submitting an administrative amendment, you only need to provide information about individual units, tanks, fugitive sources, etc. affected by the amendment.

This page allows you to edit and add potential to emit information for individual emission sources at your facility. You may not continue until all mandatory fields are entered for each emission source. Include all criteria pollutants, greenhouse gases (GHGs) and hazardous air pollutants (HAPs) for each emission source.

If the source emits particulate matter, include emissions of total particulate matter (PM), particulate matter smaller than 10 microns (PM10), and particulate matter smaller than 2.5 microns (PM2.5). Include hazardous air pollutant emissions for all permitted combustion sources. Include greenhouse gas (GHG) emissions, listed as individual GHGs and as carbon dioxide equivalents (CO2e).

Before completing this step in the application process, you must compile the necessary emission calculations for existing equipment and complete emissions calculations for any equipment newly listed. For existing equipment, make sure to account for any changes that have occurred since your permit was issued (e.g., changes to fuels, raw material contents, new test data, etc.). If you do not have these calculations from previously-submitted applications, you must complete the emissions calculations now. After you have completed the calculations, transfer the appropriate information to the page.

You are required to attach the unlocked, editable calculation spreadsheet with your application.

For specific instructions to calculate potential to emit (PTE), visit the Emission Calculations webpage.

Click Add Row to add new pollutant information for an individual emission source. You may edit some information in existing rows. These are rows that have been populated by data you have entered previously.

Emission Source — Select a piece of equipment from the drop-down list to add PTE data. If the equipment you wish to select is not present, first save any progress you have made. Then, navigate to the appropriate page (most likely the emission units page) via the navigation panel on the left and make sure that the equipment is added there.

Note: If a subject item has no pollutants, do not select that source; instead select the blank option from the Emission Source drop-down list. For example, if you enter a pollutant/emissions at the unit level that has no emissions and then pick the stack/vent for that unit, the system won't let you continue without entering a pollutant at the stack/vent. As a workaround, change the selected source to the blank option.

Click Next Emission Source to go to the next emission source. This action will take you away from the current page if all mandatory fields are entered. You will not be able to move to the next subject item if you are currently viewing the last item.

Click Previous Emission Source to go back to the previous emission source. This action will take you away from the current page if all mandatory fields are entered. You will not be able to view the previous subject item if you are currently viewing the first item.

Click the Delete icon to erase a row that you have added. You may not delete existing rows (rows that you have not added during this application process). You may not delete the first pollutant listed even if you added it; you can, however, change the pollutant listed using the drop-down list.

Required fields for each emission source:

Pollutant Name — From the drop-down list, select the name of each pollutant being emitted from the emission source (one pollutant per row). Begin by filling in all of the criteria pollutants in alphabetical order, then fill in the HAPs in alphabetical order, then GHGs.

CAS Number — The CAS number for Hazardous Air Pollutants (HAPs) is auto-populated in this box.

Potential Emissions — In the three columns, express each emission source's potential-to-emit, for each pollutant (applies to both criteria and HAPs), in each of the following three ways:

In the Potential Lbs/Hr column, report the source's maximum controlled emissions rate (e.g., after taking into account pollution control equipment) in pounds per hour. If the source is subject to a state rule, federal regulation, or self-imposed limit which requires the source's emissions to be lower than the maximum controlled emission rate, fill in the maximum emission rate taking into account the rule, regulation, or self-imposed limit. For example a unit may have a maximum controlled particulate emission rate of 10 pounds per hour, but the state industrial process equipment rule may limit the emission rate from the source to 5 pounds per hour. In this case you would fill in 5 pounds per hour as your maximum controlled emission rate. The allowable values range from 0.000000000000 – 9,999,999,999.99999.

In the Unrestricted Potential (tons/yr) column, report the emission source's maximum uncontrolled emissions in tons per year. The allowable values range from 0.000000000000 – 9,999,999,999.99999.

In the Potential Limited (tons/yr) column, report the emission source's limited controlled emissions in tons per year. The allowable values range from 0.000000000000 – 9,999,999,999.99999.
