 Proposed Rule: Mandatory Reporting of Greenhouse Gases
                                                                                           United States
                                                                                           Environmental Protection
                                                                                           Aaoncy
 The proposed Mandatory Reporting of Greenhouse Gases (GHGs) rule would require reporting of annual
 emissions of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), sulfur hexafluoride (SF6),
 hydrofluorocarbons (HFCs), perfluorochemicals (PFCs), and other fluorinated gases (e.g., nitrogen
 trifluoride, hydrofluorinated ethers [HFEs]). The proposed rule (40 CFR 98) would apply to certain facilities
 that emit GHGs and to suppliers of fossil fuels and industrial GHGs. Manufacturers of vehicles and engines
 would report GHG emissions under other existing rules,' and are not addressed further here. Reporting would
 be at the facility level, except for certain suppliers that would report at the corporate level.

 Facilities and suppliers that are subject to the proposed rule would have to comply with the General
 Provisions (40 CFR part 98, subpart A) and the provisions of all other applicable subparts of 40 CFR 98.

 Who Would Report?

 The proposed rule would apply to facilities that directly emit GHGs and to suppliers of fossil fuels and
 industrial GHGs.  Tables 1 through 3 describe the direct emitters that would report, and Tables 4 and 5 describe
 the suppliers that  would report under the proposed rule.
 Table 1. If the facility contains any of the source categories listed in this table in any calendar year starting in 2010,
 the facility would be required to report emissions from all source categories at the facility for which calculation
 methodologies are provided in any subpart of the proposed rule.

Table 2. If the facility does not contain any of the source categories listed in Table 1, then the facility would be
required to determine whether it emits 25,000 metric tons of carbon dioxide equivalent (CO2e) or more in
combined emissions from stationary fuel combustion, miscellaneous carbonate use, and the source categories listed
in this table in any calendar year starting in 2010. If so, the facility would be required to report emissions from all
source categories at the facility for which calculation methodologies are provided in any subpart of the proposed
rule.

Table 3. If the facility does not contain any of the source categories in Tables 1 or 2, then the facility would be
required to determine if the facility emits 25,000 metric tons of CO2e from stationary combustion in any calendar
year starting in 2010. If so, the facility would report emissions from stationary fuel combustion devices only.
                                              Boilers

Note: If the maximum rated heat input capacity for all stationary fuel combustion equipment is less than 30 million
British thermal units (Btu) per hour, then the facility is presumed to emit less than 25,000 metric tons of CO2e and
the facility does not have to calculate or report emissions.

Table 6 (see page 4) provides examples of how these applicability requirements would apply to different types
of facilities and suppliers.

What Information Would Be Reported?

Under the proposal, the annual emission report would include the following information:

    •   Total facility emissions in metric tons of CO2e aggregated for all source categories.
    •   Total emissions in metric tons of CO2e aggregated for all supply categories.
    •   Emissions from each source category and supply category expressed in metric tons of each GHG.
    •   Onsite electricity generation in kilowatt-hours.
    •   Total pounds of synthetic fertilizer produced and total nitrogen contained in the fertilizer.
    •   Any additional information, including unit- or process-level emissions, activity data (e.g., fuel use,
       feedstock inputs), or quality assurance/quality control data that are specified in an applicable subpart.

How Would Reports Be Submitted?

Under the proposal, the emission reports would be submitted electronically, in a format to be specified by the
EPA Administrator after publication of the final rule. Each report would be signed by a designated
representative of the owner or operator, certifying under penalty of law that the report has been prepared in
accordance with the requirements of the  rule.

What Records Would Be Retained?

Under the proposal, each facility and supplier would retain the following records for five years in electronic or
hard-copy format:

    •   A list of all units, operations, processes, and activities for which GHG emissions are calculated.
    •   The data used to calculate the GHG emissions for each unit, operation, process, and activity,
       categorized by fuel or material type.
    •   Documentation of the process used to collect the necessary data for the GHG emission calculations.
    •   The GHG emission calculations and methods used.
    •   All emission factors  used for the GHG emission calculations.
    •   Any facility operating data or process information used for the GHG emission calculations.
    •   Names and documentation of key facility personnel involved in calculating and reporting the GHG
       emissions.
    •   The annual GHG emission reports.
    •   A log book documenting any procedural changes to the GHG emission accounting methods and any
       changes to the instrumentation critical to GHG emission calculations.

Table 6. Examples of how the applicability criteria would apply at different types of facilities.
        Facility Description
 Required to
Submit a GHG
   Report?
                   Explanation
A lime manufacturing plant emits
22,000 tons per year (tpy) CO2e from
lime kilns.
     Yes
Because lime manufacturing is a source category that is
listed in Table 1, the facility would submit a report
regardless of the amount of GHGs emitted.	
A pulp mill emits 22,000 tpy CO2e in
combined emissions from stationary
fuel combustion, digester vessels,
carbonates, and wastewater treatment
operations.	
     No
Because pulp and paper manufacturing is a source
category listed in Table 2, the facility would report only
if emissions are 25,000 tpy CO2e or more.
A cheese manufacturing plant
contains:
• A gas-fired boiler that emits 15,000
  tpy CO2e;
• A biomass-fired boiler that emits
  10,000 tpy CO2e; and
• A wastewater treatment operation
  that emits 9,000 tpy CO2e.	
     No
Because food processing is a source category listed in
Table 2, the facility would report if emissions are 25,000
tpy CO2e or more. Because combustion of biogenic
fuels is excluded from the applicability computation,
nonbiogenic GHG emissions for the facility are 24,000
tpy CO2e.
An assembly plant emits 30,000 tpy
CO2e from a coal-fired boiler.
     Yes
Assembly plants are not a listed source category in
Tables 1 or 2, but the facility nevertheless would submit
a report because emissions from stationary fuel
combustion are 25,000 tpy CO2e or more.	
A university emits 24,000 tpy CO2e
from a cogeneration unit and 2,000
tpy CO2e from coal storage.
     No
Because the rule does not prescribe a method for
calculating GHG emissions from coal storage, coal
storage emissions are not counted in determining
applicability.	
An industrial gas company emits
24,000 tpy from the production of
SF6.
   Yes (as a
   supplier)

   No (as a
   facility)
The company would be subject to reporting as a supplier
(40 CFR part 98, subpart OO) because all industrial
GHG suppliers would report emissions from product
sales. The company would not report fugitive emissions
from the SF6 production processes (40 CFR part 98,
subpart L) because emissions are below 25,000 tpy
CO2e threshold for Table 2 source categories.	
A municipal solid waste landfill
generates an amount of CH4
equivalent to 40,000 tpy CO2e, but
collects and combusts 75 percent of
the CH4, emitting only 10,000 tpy
C02e.
     Yes
For a municipal landfill, the 25,000 tpy CO2e reporting
threshold is based on gas generation, not on actual
emissions.
A petrochemical plant also has an
onsite wastewater treatment operation
and stationary fuel combustion units.
Total facility emissions are 24,000 tpy
C02e.
     Yes
Because petrochemical production is a source category
listed in Table 1, the facility would report emissions
from all source categories for which the rule contains
calculation methods (including wastewater treatment
and stationary fuel combustion), regardless of the
magnitude of the emissions from the other collocated
source categories.	
A semiconductor manufacturing
facility produces 900 m2 of silicon per
year and operates fuel combustion
devices that collectively emit 26,000
tpy CO2e.
     Yes
Because the facility produces less than 1,080 m of
silicon per year, the silicon manufacturing process does
not meet the definition of semiconductor manufacturing,
as defined in Table  1. Therefore, it would evaluate
emissions from fuel combustion sources.  Because
emissions from stationary fuel combustion exceed
25,000 tpy CO2e, the facility would report emissions
from fuel combustion, but not from semiconductor
