Titanium  Dioxide Production
	      United Slates
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 titanium dioxide production processes (as defined below)
would report emissions from titanium dioxide production and all other source categories located
at the facility for which 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 titanium dioxide production source category consists of any facility that uses the
chloride process to produce titanium dioxide.

What GHGs Would Be Reported?

The proposal calls for each titanium dioxide production facility to report carbon dioxide (CO2) process
emissions from each chloride process line.

In addition, each facility would report GHG emissions for other source categories for which calculation
methods are provided in the rule. For example, facilities would report CO2, nitrous oxide (N2O), and
methane (CH4) emissions from each stationary combustion unit on site by following the requirements of
40 CFRpart 98, subpart C (General Stationary Fuel Combustion Sources). Please refer to the relevant
information sheet for a summary of the proposal for calculating and reporting emissions from any other
source categories at the facility.

How Would GHG Emissions Be Calculated?

Under the proposal, owners or operators of titanium dioxide production facilities would calculate CO2
process emissions using one of two methods, as appropriate:

   •   Facilities 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 facilities, the use of CEMS would be
       optional.
   •   Facilities without CEMS would calculate the process CO2 emissions using the equation provided
       in the rule and monthly determination of the mass of calcined petroleum coke consumed in each
       line. Petroleum coke consumption would be determined by either direct measurement or purchase
       records.

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 annual report to include the following information for each titanium dioxide production line:

   •   Annual CO2 emissions from each chloride process line (metric tons).
   •   Monthly measurements of calcined petroleum coke consumption (metric tons).
   •   Monthly production of titanium dioxide (metric tons).
   •   Monthly production capacity of titanium dioxide (metric tons).
   •   Annual operating hours for each titanium dioxide process line.
Facilities that use CEMS should also report the data specified in 40 CFR 98.34(d) of subpart C (General
Stationary Fuel Combustion Sources).
