* Split: if 50% appears in this column, then the facility's emissions have been split among two 50/50% ownership parent companies.
** CBI: if Yes appears in this column, then one or more of the supplier CO2 amounts for the facility (excluding imports and exports) have been treated as confidential by EPA. Amounts that EPA has declared to be confidential are treated as zeroes. If there are confidential amounts, the actual supplier emissions would be larger than shown. Petroleum exports are not included as supplier amounts (we assume that they were also reported as production if they were produced in the US.)
