Please refer to the Calculation Spreadsheet Archive to review obsolete calculation spreadsheets.

EPA is providing OPTIONAL calculation spreadsheets that you can use to perform the calculations called for in the emission equations. These Microsoft Excel spreadsheets can be downloaded and opened on your own computer. Just click the hyperlink on the web-form to view and download the appropriate calculation spreadsheet for the equation you are working on. You can enter the data, including equation inputs, necessary to perform the calculation for the equation, and the spreadsheets will calculate the result for you. Once you have calculated the result, enter the result onto the e-GGRT web form.

E-GGRT will NOT collect the calculation spreadsheets and you do NOT need to submit them outside of e-GGRT. The use of these calculation spreadsheets is voluntary. The spreadsheets are meant to support reporters as they complete the e-GGRT online reporting process. You do not need to use EPA’s spreadsheets to perform the calculations for the emissions equations, but you do need to keep records of these calculations (under 40 CFR 98 3(g) and additional subpart-specific provisions) whether or not you use the calculation spreadsheets provided by EPA. If you do use the spreadsheets, you may choose to maintain copies to help meet your record-keeping requirements.

Calculation spreadsheets include no rounding of results. All calculations in these spreadsheets are conducted using double decimal precision, as native in MS Excel.  The resultant values are presented on the spreadsheet in 7 decimals of precision. Users may copy the results from spreadsheets into e-GGRT manually or by using a copy and paste command.
