Subpart L Inputs Form Destruction of Previously Produced Tab

Created by Laurel Snapper on Dec 17, 2020

Subpart L facilities are required to report information on the destruction of fluorinated GHGs previously produced, including the identity and quantity of each fluorinated GHG destroyed. Enter this information using the following steps.

In the Subpart L inputs Form spreadsheet, go to the "Destruction of Prev. Produced" tab.

Part 5 - Destruction of F-GHGs that were Previously Produced

First, enter information in columns C through I, shown below.

Data Element	Instructions
Destruction Device	Enter an identifier for each destruction device.
F-GHG	Select an f-GHG from the dropdown list. The "f-GHG List for Subpart L" tab of the spreadsheet contains a detailed list of the gases associated with fluorinated gas production. If not listed, select "Other f-GHG chemical not listed" and enter the information in the appropriate columns.
CASRN	This field will autofill with the Chemical Abstracts Service Registry Number (CASRN) based on the F-GHG selection.
Other f-GHG (columns F through I): F. Other F-GHG Not Listed G. Other CASRN H. Other Chemical Formula I. Specify F-GHG Group for Other F-GHG Not Listed for Purposes of Estimating GWP	Provide the following information if "Other f-GHG chemical not listed” was selected in the “F-GHG” field: F. Enter the name of the Fluorinated GHG emitted (e.g., Nitrogen trifluoride) G. Enter the Chemical Abstracts Service Registry Number (CASRN) (e.g., 7783-54-2) H. Enter the gas chemical formula (e.g., NF3) I. Select the Fluorinated GHG (F-GHG) Group of which this "Other" F-GHG is a member from the dropdown list of f-GHG groups.

Equation L-31

Continue entering information in columns K and L. Column M contains a formula that will calculate the Total Mass Emitted using Equation L-31 and will autofill
