Subpart PP Supply Information

Created by John Gilchrist, last modified by Isaac Locke on Dec 31, 2019

This page provides a step-by-step description of how to enter subpart PP Suppliers of Carbon Dioxide supply data.

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
