Please note the following changes to e-GGRT effective September 19th, 2011. These changes affect the small number of e-GGRT users who used e-GGRT BEFORE September 19th and reported difficulty completing a portion of their reporting in very specific cases. EPA has provided a “know issues” page on its e-GGRT Help site (http://www.ccdsupport.com) The key updates are summarized below:
For Subpart Q (Iron and Steel) facilities reporting flares
Issue: e-GGRT had been directing users to use Equations Y-4 and Y-5 to calculate CH4 and N2Ofor subpart Q flares. However, the rule requires that users to calculate those emissions based on Equation C-9a. In addition, in certain cases annual reports for subpart Q were not in all cases including the CO2, CH4, and/or N2O emissions for each flare reported although the rolled-up subpart-level and facility-level emissions values were correct.
Workaround: The Subpart Q page for flares now references Equation C-9a and the associated optional calculation spreadsheet and the annual report will include all flare emissions values. Users who have prepared an annual report for Subpart Q that includes flares before September 19 should ensure their CH4 and N20 emission estimates are consistent with requirements of Equation C-9a and regenerate their report. If you are submitting emission Subpart Q Flares using the XML you should note that the “Fraction of Carbon in the Flare Gas” data element related to Equation Y-4, which was to be reported prior to the change, is no longer applicable.
For Subpart AA (Pulp and Paper) facilities with pulp mill lime kilns
Issue: Several of the optional calculation spreadsheets referenced by e-GGRT (for Eq. C-8, C-8a, C-8b, C-9a, and C-9b) did not provide emission factors for Table AA-2 which are used to calculate CH4 and N20 emissions.
Workaround: These spreadsheets have now been updated to include the emission factors listed in Table AA-2 and are available to be downloaded at: Using Subpart C Calculation Spreadsheets . If you have included emissions from pulp mill lime kilns in your annual report please ensure that you have used the correct emission factors.
For subpart HH (Municipal Landfills) with multiple gas monitoring locations
Issue: The “Equation HH-6, HH-7, and HH-8 Multi” tab of the Equation HH-6, HH-7, and HH-8 Optional Calculation Spreadsheet referenced by e-GGRT contained an error in cell C80.
Workaround: The spreadsheet for these equations has now been updated to correct this error and is available for download at: Using Subpart HH Calculation Spreadsheets. Please make sure you are using the most up to date spreadsheet by checking to ensure you are using version RY2010.R.03. If you have already run your calculation using an incorrect formula, please rerun the calculation using the correct formula, insert the correct value in e-GGRT, and then regenerate, submit, and certify your corrected report.
These changes along with a number of other cosmetic and explanatory modifications will make it easier for users to complete their reporting. As always, if you encounter difficulty the GHGRP Help Desk is available to help. Please call the help desk at 877-444-1188 or send a request via e-mail at help@ccdsupport.com. If you call outside of help desk hours (9am – 5pm EST, Monday thru Friday) please leave a voice mail and will return your call first thing in the morning.
