Proposed Rule: Mandatory Reporting of Greenhouse Gases                         Environmental Protection


Under the proposed Mandatory Reporting of Greenhouse Gases (GHGs) rule, owners or
operators of facilities that contain lead production processes (as defined below) and that emit
25,000 metric tons of GHGs per year or more (expressed as carbon dioxide equivalents) from
stationary combustion, miscellaneous use of carbonates, and other source categories (see
information sheet on General Provisions) would report emissions from all source categories
located at the facility for which emission calculation methods are defined in the rule.  Owners or
operators would collect emission data; calculate GHG emissions; and follow the specified
procedures for quality assurance, missing data,  recordkeeping, and reporting.

How  Is This Source Category Defined?

Under the proposal, the lead production source category consists of primary lead smelters and secondary
lead smelters. A primary lead smelter is a facility engaged in the production of lead metal from lead
sulfide ore concentrates through the use of pyrometallurgical techniques (smelting). A secondary lead
smelter is a facility at which lead-bearing scrap materials (including but not limited to lead-acid batteries)
are recycled by smelting into elemental lead or lead alloys.

What GHGs Would Be Reported?

The proposal calls for lead production facilities to report the following emissions:

       Carbon dioxide (CO2) process emissions from each smelting furnace used for lead production as
       required by this subpart.
       CO2, methane (CFL,), and nitrous oxide (N2O) emissions from fuel combustion at each blast
       furnace, rotary furnace, and reverberatory furnace, and at each stationary combustion unit by
       following the requirements of 40 CFRpart 98, subpart C (General Stationary Fuel Combustion
       Sources). The information sheet on general stationary fuel combustion sources summarizes the
       proposal for calculating and reporting emissions from these units.

In addition, each facility would report GHG emissions for any other source categories for which
calculation methods are provided in other subparts of the rule.

How  Would GHG Emissions Be Calculated?

For CO2 emissions from each smelting furnace, the proposal calls for facilities to use one of two methods
as appropriate:

       Lead smelting furnaces with certain types of continuous emissions monitors (CEMS) in place
       would report using the CEMS and follow the methodology of 40 CFR part 98, subpart C to report
       total  CO2 emissions from calcination and fuel combustion. At other lead smelting furnaces, the
       use of CEMS would be optional.

Greenhouse Gases Rule.

     Facilities without CEMS would calculate CO2 process emissions on the basis of monthly
       consumption of reducing agents and other carbon containing inputs using the following
       measurements:
           o  Total mass of each carbon-containing material (including ore, scrap, flux materials,
              carbonaceous materials, coke for blast and other smelting furnaces, and any other
              material) that is fed, charged, or otherwise introduced into each smelting furnace for each
              calendar month.
           o  Mass fraction of carbon in each carbon-containing material other than fuel that is fed,
              charged, or otherwise introduced into each smelting furnace used. Coke used in blast
              and/or smelting furnaces is included as a feedstock rather than as a fuel in this mass-
              balance procedure. The mass fraction would be determined either from information
              provided by the material supplier or by monthly measurements of a representative sample
              of carbon-containing materials.

What Information Would Be Reported?

In addition to the information required by the General Provisions at 40 CFR 98.3(c), the proposal calls for
each lead production facility to report the following information:

     Total annual CO2 emissions from each smelting furnace (metric tons) and the method used to
       estimate these emissions.
     Annual facility lead production capacity (metric tons).
     Annual facility production quantity (metric tons).
     Number of facility operating hours per calendar year.
     If the facility uses the carbon input mass-balance procedure, it would report the following
       information for each carbon-containing input material consumed or used (other than fuel) in the
       smelting furnaces:
           o  Annual material quantity (metric tons).
           o  Annual weighted-average carbon content, based on monthly carbon analysis, determined
              for each material and the method used for the determination (e.g., supplier provided
              information, analyses of representative samples collected).

Facilities that use CEMS would also report the data specified in 40 CFR 98.34(d) of subpart C (General
Stationary Fuel Combustion Sources).
