As was announced in 2009, beginning with the 2010 calendar year Emission Inventory process a new system would be used. This system 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 infromation as well as infromation about emission units, release points (stacks) and basic process information. The FI is designed for the facility to maintain on a contimnuous 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 ares of the FI be reviewed and updated or corrected to avoid submitting errors during the EI part of the process.
  
• Emission Inventory (EI) - The EI contains process 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 option to opt out of participating in the EI process is available after providing information about the facility and EI contact. The 2010 EI data will be prepopulated using data from the last Emission Inventory (2008 0r 2009) in which a facility participated.

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 last year due to 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 aalthough 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. The deadline for the 2010 calendar year Emission Inventory (EI) will be announced as soon as the EI part of the web application is ready to be used.

For assistance in calculating the PTE for a facility, please see the Potential to Emit Guidelines web page.

NOTE: Facilities identified by the Air Protection Branch (APB) as those that might need to participate in the Calendar Year 2011 emissions inventory will be receiving information about the process in the mail between late January and early February 2012.

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 - August 1, 2012. If your facility’s potential emissions of ALL the pollutants in the following table are less than the indicated thresholds, you may choose to opt out of participation in the emission inventory process. To opt out, choose the appropriate option on the web form after loging on and follow the provided instructions.
