CLEAN AIR ACT HAZARDOUS AIR POLLUTANT LIST
David Constans and David Gossman

In the Clean Air Act (CAA) the EPA has chosen a number of compounds, primarily organics, that are deemed to be Hazardous Air Pollutants (HAPs) the emissions of which are to be controlled. GCI has tabulated this list and compared it with current regulations that already affect BIFs.

Before presenting the HAPs list, a few comments are appropriate. There are a number of compounds that are listed in Part 266, Appendix VIII (the BIF PIC list) that are not listed as HAPs. It seems curious that the CAA does not consider these compounds to be worthy of inclusion in the HAPs list. Also, very few of the HAPs have been determined to be in cement kiln stack emissions. Some of these HAPs are compounds that can not be formed in the cement process and/or could not exist in the exhaust of a cement kiln. They would either disassociate or react with common stack gas constituents such as water or alkali salts. A number of these compounds on the HAPs list do not have recognized and/or validated sampling and analytical methods. GCI has attempted to select a sampling method based on information from stack sampling contractors and by consulting EPA's "Stationary Sources Sampling and Analysis Guide." GCI makes no claim that the methods listed are appropriate for all stack gas sampling conditions, or that there is a validated analytical method that is compatible with the sample method. It is our intent, in presenting this data, to aid our clients in understanding the impact of the seemingly simple request: "Test the stack for HAPs emissions." GCI will continue to refine this list and encourage any comments or suggestions that would aid in this effort. The following are abbreviations used in the methods column of the table:

NMG - No Method Given
? - Questionable method
? V - Questionable validity of sample method or of the analysis of the sample
NV - Not Validated, sampling or analysis method has not been validated for this compound
