Using e-GGRT to Prepare your Subpart V Report

Created by Sokha Chea, last modified by Isaac Locke on Dec 17, 2020

Starting with reporting year 2014, you must upload a separate inputs to equations spreadsheet for Subpart V. The inputs to equations will be used by the Inputs Verifier Tool (IVT) to calculate N₂O emissions and for verification purposes, but will not be stored by EPA. The calculated emissions values and the results of the verification checks (the verification summary, viewable from the "Subpart Overview" page) will be stored by EPA.

This page provides an overview of Subpart V reporting through e-GGRT. More detailed information regarding Subpart V reporting can be found in the Subpart V Training Presentation

Once you have added Subpart V to the list of subparts you will report and have clicked on the "Open" link next to Subpart V, you will see the following screen:

Completed Subpart V Reporting Form and Inputs Form

Starting with reporting year 2014, you must upload a separate inputs to equations spreadsheet for Subpart V. The inputs to equations will be used by the IVT to calculate N₂O emissions and for verification purposes, but will not be stored by EPA. The calculated emissions values and the results of the verification checks (the verification summary, viewable from the "Subpart Overview" page) will be stored by EPA.

After you have successfully uploaded your completed Subpart V reporting form, the page will be updated to reflect the file you have uploaded. Then you will be able to upload the IVT file.

To upload your IVT file, click the BROWSE button in the UPLOAD COMPLETED INPUTS FORM section near the bottom of the screen.

In the File Upload window that appears, navigate to the folder containing your IVT file, select the file, and click the OPEN button in the lower right of the window. The filepath of your IVT file will appear in the text box immediately to the left of the BROWSE button.

To complete the upload process, click the blue UPLOAD button immediately to the right of the BROWSE button.

When you have successfully uploaded the IVT file, it will show a calculated result of annual N₂O emissions in metric tons under the file name. You also can overwrite the data by entering your own results and clicking SAVE. Additionally, all Annual annual N₂O emissions which have been estimated using an Administrator Approved Alternative Method will be calculated and displayed in metric tons below the review of annual N₂O emissions by other methods.

If you attempt to upload a file but your file is not accepted by e-GGRT, it may be because your file has a fatal flaw or is missing essential data. The reason why the file was not accepted is displayed as a screen error on the upload page. For an example of a screen error message, see below.

During the upload, e-GGRT will generate a validation report which will list potential deficiencies or issues with your reporting form. Click on the "Subpart V: View Validation" link to review your validation report. An explanation of the validation report and the process for correcting validation issues prior to submission is presented in Reporting Form Validation

Once you have addressed the validation issues to the extent you believe necessary, and once you have completed any other applicable subparts, you must generate, review, certify, and submit your annual report as described in How to Submit an Annual Report
