Suppliers of Carbon Dioxide
                                                                                  United States
Final Rule: Mandatory Reporting of Greenhouse Gases                             ^aimrriental Prot9ction

Under the Mandatory Reporting of Greenhouse Gases (GHGs) rule, suppliers of carbon dioxide (CO 2)
that meet the applicability requirements of the rule (see information sheet on General Provisions) must
report CO2 emissions that would result from the complete release of the product that they place into
commerce.

How Is This Source Category Defined?

Suppliers of CO2 consist of the following:
   •   Facilities with production process units that capture and supply CO2 for commercial applications
       or that capture and maintain custody of a CO2 stream in order to sequester or otherwise inject it
       underground.

   •   Facilities with CO2 production wells that extract or produce a CO2 stream for purposes of
       supplying CO2 for commercial applications or that extract and maintain custody of a CO2 stream
       in order to sequester or otherwise inject it underground.

   •   Importers of bulk CO2, if total combined imports of CO2 and other GHGs exceed 25,000 tons of
       CO2 equivalents (CO2e) per year.

   •   Exporters of bulk CO2, if total combined exports of CO2 and other GHGs exceed 25,000 tons
       CO2e per year.

This source category does not include entities that:

   »   Store CO2 above ground or through geologic sequestration.

   »   Use CO2 in enhanced oil and gas recovery.

   »   Transport or distribute CO2.

   »   Purify, compress, or process CO2.

   »   Use CO2 on site that was captured on site.

   »   Import or export CO2 in equipment.

What GHGs Must Be Reported?

Suppliers of CO2 must report the mass of CO2 that is captured from production process units, extracted
from production wells, imported, and exported.

How Should GHG Emissions Be Calculated?

Choose from one of three different methods to calculate the annual mass of CO2 supplied:
40 CFR 98, subpart PP                           1                            EPA-430-F-09-016R

    •   If using mass flow meters, calculate CO2 supplied by multiplying the mass flow rate of the CO2
       stream by its CO2 concentration.

    •   If using volumetric flow meters, calculate CO2 supplied by multiplying the volumetric flow rate
       of the CO2 stream by its CO2 concentration and density.

    •   If using weigh bills, scales, or load cells, calculate CO2 supplied by adding the mass of CO2 in all
       containers.

These calculations must be based on CO2 stream or mass measurements made prior to any subsequent
purification, processing, or compressing of the gas.

A checklist for data that must be monitored is available at:
www.epa.gov/climatechange/emissions/downloads/checklists/supplierscarbondioxide.pdf.

What Information Must Be Reported?

In addition to the information required by the General Provisions at 40 CFR 98.3(c), report the following
information (at the corporate level for importers and exporters; at the facility level for all others):
    •   Annual mass in metric tons of CO2 for all flow meters.
    •   For each flow meter:
           o   Annual mass of CO2 (metric tons).
           o   Quarterly mass (metric  tons) or volumetric flow (standard cubic meters) of CO2
           o   Type of equipment used to measure the flow of the CO2 stream and the standard used to
               operate and calibrate the equipment.
           o   Quarterly concentration of the CO2 stream (weight percentage CO2).
           o   Standard used  to measure the concentration.
           o   Quarterly density of the CO2 stream (metric tons per standard cubic meter), for
               volumetric flow meters only.
           o   Method used to measure the density, for volumetric flow meters only.
    •   Annual mass of CO2 for all containers (metric tons).
    •   For containers of CO2  imported or exported, the type of equipment used to measure CO2 mass
       and the standard used to operate and calibrate the equipment.
    •   Number of days in the  reporting year for which substitute data procedures were used to measure
       quantity, concentration, and density.
    •   Percentage of the CO2  stream that is biomass-based.
    •   Annual quantity of CO2 transferred to the following end-use applications (if known):
           o   Food and beverage.
           o   Industrial and  municipal water/wastewater treatment.
           o   Metal fabrication, including welding and cutting.
           o   Greenhouse uses for plant growth.
           o   Fumigants (e.g., grain storage) and herbicides.
           o   Pulp and paper.
           o   Cleaning and solvent use.
           o   Fire fighting.
           o   Transportation and storage of explosives.
           o   Enhanced oil and natural gas recovery.
           o   Long-term storage (sequestration).
           o   Research and development.
           o   Other.
