Subpart PP supply reporting is different for four types of suppliers:

• Supplier Type A: Capture Facilities That Use Flow Meter(s) With or Without Segregation
• Supplier Type B: Importers, Exporters, and Extract Facilities That Use Flow Meter(s)
• Supplier Type C: Capture and Extract Facilities With Stream(s) That Deliver CO₂ to Containers
• Supplier Type D: Importers and Exporters That Use Containers

Capture Facilities that use one or more flow meters, with or without segregation, should proceed to the section titled "Supplier Type A: Capture Facilities That Use Flow Meters" and may disregard all other sections.

Importers, Exporters, and Extract Facilities that use one or more flow meters should proceed to the section titled “Supplier Type B: Importers, Exporters, and Extract Facilities That Use Flow Meters With No System Aggregation” and may disregard all other sections.

Capture and Extract Facilities with one or more streams that deliver CO₂ to containers should proceed to the section titled “Supplier Type C: Capture and Extract Facilities With Streams That Deliver CO₂ to Containers” and may disregard all other sections.

Importers and Exporters that use containers should proceed to the section titled “Supplier Type D: Importers and Exporters That Use Containers” and may disregard all other sections.

Supplier Type A:  Capture Facilities That Use Flow Meters

The supply information required for capture facilities that use flow meters includes three steps:

• A1: Flow Meter Information
• A2
  • A2.1: Equation PP-1 (mass-based measurements)
    OR
  • A2.2: Equation PP-2 (volume-based measurements)
• A3
  • A3.1: Equation PP-3a (aggregation for flow meters with no segregation)
    OR
  • A3.2: Equation PP-3b (aggregation for flow meters with segregation)

The steps required for Capture Facilities that use flow meters include the use of either Step A2.1 or Step A2.2, but not both and either Step A3.1 or Step A3.2, but not both.

Your selection of a flow meter type and measurement basis will determine whether e-GGRT uses Step A2.1 or Step A2.2 and A3.1 or A3.2 to calculate CO₂ quantities.

If measurements are reported on a mass basis, e-GGRT will use Step A2.1: Equation PP-1 to calculate CO₂ quantities.

If measurements are reported on a volumetric basis, e-GGRT will use Step A2.2: Equation PP-2 to calculate CO₂ quantities.

e-GGRT will use Step A3.1: Equation PP-3a to calculate facility-level CO₂ quantities for flow meters with no segregation by summing the annual mass of CO₂ measured by each individual flow meter.

e-GGRT will use Step A3.2: Equation PP-3b to calculate facility-level CO₂ quantities for flow meters with segregation by subtracting the total annual mass of CO₂ measured by all flow meters downstream of the point(s) of segregation from the total annual mass of CO₂ measured by all flow meters upstream of the point(s) of segregation.  For example, if your facility captures a portion of CO₂ for use onsite, and supplies the other portion for commercial applications or to inject or sequester it underground, e-GGRT would use the value you entered for total CO₂ captured (flow meter upstream of segregation) less the value you entered for CO₂ used onsite (flow meter downstream of segregation) to calculate the CO₂ quantity supplied.  If you supply captured CO₂ in containers, see Supplier Type C.

Each Step is described below.

Step A1: Flow Meter Information

To add a flow meter, click the link labeled “ADD a Flow Meter” located below the FLOW METERS table.

The following information is required for each individual flow meter on this screen:

• A unique flow meter name or ID
• The location of the flow meter in relation to dehydration equipment, compression equipment, and other processing equipment
• The percentage of the CO₂ stream that is biomass-based
• Measurement type
• If you use flow meters with segregation, you must also report the location of the flow meter in relation the point of segregation

Use the text boxes and radio buttons to enter all required information for each flow meter.

If you have “other processing equipment,” describe it in the text box. If you have more than one type of “other processing equipment,” describe each type in the text box, including whether it is upstream or downstream of the flow meter.

If you don't have all the data, you can enter some now, save it, then finish it later.

When finished, click SAVE. You will be returned to the OVERVIEW screen, which will display the flow meter information you just saved.

Repeat this step until you have added all flow meters. Once all flow meters used at your facility have been added to the table, click OPEN to enter measurement data for each flow meter.

For each flow meter measuring on a mass basis, e-GGRT will calculate GHGs using Equation PP-1 described in Step A2.1.

For each flow meter measuring on a volume basis, e-GGRT will calculate GHGs using Equation PP-2 described in Step A2.2.

Step A2.1: Equation PP-1 (mass-based measurements)

This page will be blank until you enter more data in subsequent screens. Use the radio buttons to select whether you would like to report results calculated by e-GGRT or enter your own results.

Express the concentration as a decimal fraction (e.g., enter 0.9 for a concentration of 90 percent). If you used more than one standard during the reporting year, enter them all.

When finished, click SUMMARY.

To view the validation page for Equation PP-1, click the link labeled “View Validation.”

Once all data has been entered for this flow meter, click FINISHED.

Step A2.2: Equation PP-2 (volume-based measurements)

If you selected the flow meter measurement type as “concentration in weight percentage” on the Add/Edit Flow Meter page, blank text boxes will be displayed, and you should enter the density of the CO₂ stream and the name of the standard used to measure CO₂ stream density. If you used more than one standard during the reporting year, enter them all.

If you selected the flow meter measurement type as “concentration in volume percentage” on the Add/Edit Flow Meter page, populated text boxes will be displayed with the density of CO₂ that is required in the rule (0.001868 metric tons per standard cubic meter). A text box for the standard used to measure CO₂ density will not be displayed.
