In the inputs spreadsheet, go to the "Production Transformation" tab. There are three tables on this tab: Part 1, Part 2, and Part 3.
- Part 1 and Part 2 - Required for all facilities reporting Subpart L
- Part 3 - Complete this table only if (1) your facility produces only one fluorinated gas product, (2) emissions consist of a major fluorinated GHG constituent of a fluorinated gas product, and (3) the product is sold or transferred to another person.
Worksheet Navigation
To navigate between tables, use the navigational buttons provided at the top of each table or use the scroll bars.
Enter the required f-GHG production emissions information by using the steps below.
