Issues and Workarounds for e-GGRT RY2024
If you submit GHG annual reports via the bulk XML upload method, see XML Known Issues.
Subject Area | Description
|
|---|---|
| Subpart Y | Error when editing Equation Y-1a CO2 emissions Issue: Subpart Y users will receive a dialog box when editing the Equation Y-1a CO2 emissions value for a flare, as follows:
However, the flare's Equation Y-4 CH4 emission calculation will not refresh. Workaround: You will need to delete that flare unit, add it back in, re-enter your data, and save. Reference: #571 |
| Optional Calculation Spreadsheets | Subpart C Optional Calculation Spreadsheets contain old GWP values Issue: Several Subpart C Optional Calculation Spreadsheets contain hard-coded GWP values for CH4 and N2O, and will not estimate RY2024 CO2 equivalent emissions correctly. The spreadsheets are found at https://ccdsupport.com/confluence/display/help/Optional+Calculation+Spreadsheet+Instructions. The Agency updated GWPs this year and in particular the RY2024 GWP for Methane is 28 and the RY2024 GWP for Nitrous Oxide is 265. While e-GGRT takes these new GWPs into consideration, users with their own calculation spreadsheets and XML reporters must incorporate revised GWP depending on the reporting year being submitted. For more information about changing GWPs please consult: https://www.epa.gov/system/files/documents/2024-07/gwp_update_2024.pdf. For more detail on the GWPs to be used by reporting year please consult: https://ccdsupport.com/confluence/display/help/Table+A-1+of+Subpart+A+of+Part+98+-+Global+Warming+Potentials. Workaround: Until the spreadsheets can be corrected, you must update the GWP values as appropriate (these workbooks are not locked) |
| Trend Report | RY2020 and RY2021 "Adjusted" CO2 equivalent values may be incorrect for Suppliers reporting under Subparts LL-QQ Issue: The "By CO2e" trend report calculates adjusted CO2 equivalent values by applying the new RY2024 GWP values (4/25/24 final rule) to prior year emissions values. These adjusted values are shown on the bottom half or the report in the "ADJUSTED" section of the report, which follows the "AS SUBMITTED" section of the report. RY2021 Adjusted values for "CO2e from products supplied (LL-QQ)" are incorrectly shown on the "CO2 sequestered (RR)" row, and RY2020 Adjusted values for "CO2e from products supplied (LL-QQ)" are not correctly included in the report. The RY2020 column incorrectly includes the RY2021 value for "for "CO2e from products supplied (LL-QQ)". Workaround: None. This issue will be addressed in a future e-GGRT maintenance release. Reference: #516 |
| Subpart O | Validation message 0-088 is incorrectly flagged Issue: Subpart O users will receive validation message O-088 which states "The annual HFC-23 emission for reporting year 2024 is NNN metric tons. This value is significantly different from the 2023 annual HFC-23 emissions of YYY metric tons" Workaround: You may ignore this message. Reference: #468 |
| Subpart W | Incorrect calculations in the RY24 Subpart W Optional Calculation Tool workbook with update date of 1/17/2025 Issue: Errors in calculation formulas for pneumatic devices, centrifugal compressors, and reciprocating compressors, equipment leaks in the Optional Calculation Workbook Resolved: Download revised version 4 (v4) of the Optional Calculation Workbook with an update date of 2/18/2025 at Optional Calculation Spreadsheet Instructions |
| Subpart W | In the supersized Subpart W form with last update last update prior to 3/20/2025, some fields do not auto populate data Issue: Missing formula to populate sub-basin ID in sections of Table AA.1.ii and Table F.2 in the supersized reporting form. Missing formula to populate the Unit ID or Name in sections of Tables D.3, D.4, and D.5 Resolved: Download revised version of the Subpart W reporting form with an last update date of 3/20/25 at Reporting Form Instructions |
| Subpart W | In the Subpart W form with last update prior to 3/20/2035, the Natural gas distribution industry segment calculated total emissions on worksheet (q,r) Equipment Leaks is incorrect Issue: The calculated total emissions on worksheet (q,r) Equipment leaks is counting emissions in for current year T-D Station emissions and T-D transfer station emissions in multi-year Resolved: Download revised version of the Subpart W reporting form with an last update date of 3/20/25 at Reporting Form Instructions |
