Submit an Emissions Inventory

Facility Inventory (FI) and the 2020 CY Emission Inventory (EI)

GECO EI application will open on January 25, 2021

CAERS EI (via EPA CDX) will open in March 2021

This year, Georgia will continue using the Combined Air Emissions Reporting System (CAERS) for the 2020 Emissions Inventory data collection instead of the GECO EI online application system.

To begin the 2020 EI application process, you are required to log into the GECO EI online application and provide us with your preparer(s) and certifier contact information.  If your facility does not meet or exceed any pollutant thresholds or if your facility did not operate from January 1 of 2020 to December 31 of 2020, you will be allowed to opt-out of the 2020 EI.  For all other facilities, you will be given a link through the GECO website to log on to CAERS via the EPA CDX website to work on the 2020 EI.

There are two new roles on the EPA CDX platform for the 2020 EI submission.  The "preparer" role is for any individual that creates and prepares reports but cannot certify the submittal on behalf of the facility.  The "certifier" role is for a representative of the facility that is authorized to submit an emissions report to the state of Georgia.

Georgia EPD and the U.S. EPA have prepared a user manual for CAERS (see “EI resources” below).   Webinars and live virtual help sessions are available to help transition facilities to CAERS.  Due to the uncertainty around COVID-19, in-person training will not be provided.  For additional information regarding the webinar and live virtual training, please visit https://geco.gaepd.org/EventRegistration/.

All Part 70 major source facilities must submit Emission Inventory data. The Emission Inventory System (EIS) consists of two parts - the Facility Inventory (FI) and the Emission Inventory (EI).

  • Facility Inventory (FI) - contains the emission units, release points, and process details that usually remain the same from year to year. The FI has been prepopulated with the most recently submitted facility information.
  • Emission Inventory (EI) - contains the annual process details, operating parameters, and emissions that usually change from year to year. During the Opt-In/Opt-Out process of the EI, you will be allowed to prepopulate the EI with data from your most recent submittal.

The emission inventory is required by federal regulation 40 CFR Part 51 - Air Emissions Reporting Requirements (AERR) and requires that emissions data be collected from certain facilities by all state agencies responsible for regulating air pollution. This is being conducted under the authority of Georgia Rule 391-3-1-.02(6)(b)1.(i).

Significant changes were made after the new AERR rule that was finalized in December 2008. The definition of a point source was changed to be more in line with a Title V major source based on potential emissions. Therefore, the threshold tables are based on potential emissions although actual emissions are reported in the data collection process. The State also has less time to submit the completed inventory to EPA, resulting in earlier facility submittal deadlines.

For assistance in calculating the PTE for a facility, please see the Potential to Emit Guidelines web page. Additionally, prior to 2015, the initial or renewal Title V application for the facility will have information on the facility wide PTE and can be found in the Title V Applications Online website.

NOTE: Facilities identified by the Air Protection Branch (APB) as those that might need to participate in the Calendar Year 2020 emissions inventory should have received information about the process by email on January 25, 2021.

Which Facilities Need to Submit Data for Calendar Year 2020?

Facilities whose potential emissions equal or exceed the thresholds shown in the table below for any of the indicated pollutants are required to submit emissions data by the deadline - June 30, 2021. To assist facilities in determining their need to participate in the NEI, participation questions have been introduced in GECO for the 2021 EI submittal.

Calendar Year 2020 Potential Emission Thresholds for all facilities in Georgia

Pollutant Triennial Year PTE Thresholds
(tons per year)
SOx ≥ 100
VOC ≥ 100
NOx ≥ 100
CO ≥ 1000
Pb ≥ 0.5 (actual)
Primary PM10 ≥ 100
Primary PM2.5 ≥ 100
NH3 ≥ 100

 

NOTE: Facilities whose NOx and/or VOC actual emissions are greater than 25 tons per year are required to submit an annual Emissions Statement if they are located in the following counties: Barrow, Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Newton, Paulding, Rockdale, Spalding, and Walton. For additional information, go to the Emissions Statement webpage.

If you have any questions regarding the 2020 EI or trouble accessing the GECO system or the EPA CDX platform, please contact Emissions.Inventory@dnr.ga.gov.
