Titanium Dioxide Production
- United States
Final Rule: Mandatory Reporting of Greenhouse Gases ^aimrriental Prot9ction
Under the Mandatory Reporting of Greenhouse Gases (GHGs) rule, owners or operators of facilities that
contain titanium dioxide production processes (as defined below) must 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 are required to 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?
The titanium dioxide production source category consists of any facility that uses the chloride process to
produce titanium dioxide.
What GHGs Must Be Reported?
Each titanium dioxide production facility must report carbon dioxide (CO2) process emissions from each
chloride process line.
In addition, each facility must report GHG emissions for other source categories for which calculation
methods are provided in the rule. For example, facilities must 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 rule requirements for calculating and reporting emissions from
any other source categories at the facility.
How Must GHG Emissions Be Calculated?
Reporters must calculate CO2 process emissions using one of two methods, as appropriate:
• Installing and operating a continuous emission monitoring system (CEMS) according to the
requirements specified in 40 CFRpart 98, subpart C.
• Calculating the process CO2 emissions for each process line using monthly measurements of the
mass and carbon content of calcined petroleum coke.
However, if process CO2 emissions from titanium dioxide production are emitted through the same stack
as a combustion unit or process equipment that uses a CEMS and follows Tier 4 methodology in subpart
C to report CO2 emissions, then the reporter must use the CEMS to measure and report combined CO2
emissions from that stack instead of using the calculation procedures in subpart EE (Titanium Dioxide
Production).
A checklist for data that must be monitored is available at:

What Information Must Be Reported?
In addition to the information required by the General Provisions at 40 CFR 98.3(c), each annual report
must include the following information for each titanium dioxide production line:

-------
If a CEMS is used to measure emissions, then report under this subpart the relevant information required
under 40 CFR, subpart C for the Tier 4 Calculation Methodology and the following information for each
process line:
• Identification number of separate chloride process lines.
• Annual consumption of calcined petroleum coke (tons).
• Annual production of titanium dioxide (tons).
• Annual production capacity of titanium dioxide (tons).
• Annual production of carbon-containing waste (tons), if applicable.
If a CEMS is not used to measure emissions, then the following information must be reported:
• Identification number of each process line.
• Annual CO2 emissions from each chloride process line (metric tons/year).
• Annual consumption of calcined petroleum coke for each process line (tons).
• Annual production of titanium dioxide for each process line (tons).
• Annual production capacity of titanium dioxide for each process line (tons).
• Monthly consumption of calcined petroleum coke for each process line (tons).
• Annual production of carbon-containing waste for each process line (tons), if applicable.
• Monthly production of titanium dioxide for each process line (tons).
• Monthly carbon content factor of petroleum coke from the supplier (percent by weight expressed
as a decimal fraction).
• Whether monthly carbon content of the petroleum coke is based on reports from the supplier or
through self measurement using applicable American Society for Testing and Materials (ASTM)
Standard Test Methods.
• Carbon content for carbon-containing waste (percent by weight expressed as a decimal fraction).
• If carbon content of petroleum coke is based on self measurement, the ASTM Standard Test
Methods used.
• Sampling analysis results of carbon content of petroleum coke as determined for QA/QC of
supplier data under 98.314(d) (percent by weight expressed as a decimal fraction).
• Number of separate chloride process lines located at the facility.
• The number of times in the reporting year that missing data procedures were followed to measure
the carbon content of petroleum coke (number of months); petroleum coke consumption (number
of months); carbon-containing waste generated (number of months); and carbon content of the
carbon-containing waste (number of times during year).
