A Branch of the Georgia Environmental Protection Division

Emissions Inventory System (EIS)

Facility Inventory (FI) and the 2016 CY Emission Inventory (EI)

Submittal Deadline: June 30, 2017

All Part 70 major source facilities must respond to the call for participation in the annual Emission Inventory data submittal. This process is called the Emission Inventory System (EIS) and consists of two parts - the Facility Inventory (FI) and the Emission Inventory (EI).

  • Facility Inventory (FI) - The FI contains the facility and contact information as well as information about emission units, release points (stacks) and basic process information. The FI is designed for the facility to maintain on a continuous basis during the year. The only periods of time that the FI may not be accessible is immediately after facility submittal of the annual Emission Inventory. During this brief period, the Air Protection Branch reviews the data submitted for completeness. It is important that all areas of the FI be reviewed, updated, or corrected to avoid submitting errors during the EI part of the process.
  • Emission Inventory (EI) - The EI contains information that may change from year to year and annual emissions information for pollutants from processes. The EI part of the EIS closes at the end of each annual EI collection process.

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. Georgia's Air Protection Branch is also collecting emissions data to obtain information necessary for the development of State Implementation Plans required by the 8-hr ozone NAAQS and the PM2.5 NAAQS. 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, the most recent 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 2016 emissions inventory will be receiving information about the process in the mail between January and early February 2017.

Which Facilities Need to Submit Data for Calendar Year 2016?

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, 2017. To assist facilities in determining their need to participate in the EIS, participation questions have been introduced for the 2016 EIS submittal.

NOTE: Facilities whose NOx and/or VOC actual emissions are greater than 25 tons per year and are in the Atlanta metro maintenance area are required to submit an annual Emissions Statement. For additional information, go to the Emissions Statement webpage.

To respond to Emission Inventory data request, all Part 70 major sources must use the Georgia Environmental Connections Online application or simply GECO. GECO was created to enable a user to access multiple facilities through one user login. GECO also provides additional facility information, as well as the online applications we have made available in the past, including the Emission Inventory. To activate your account, please register in GECO and follow the instructions. If you need assistance with your GECO registration, please contact the APB Emissions and Control Strategies Unit staff at (404)363-7000.
