Rochelle,

In response to the your request, attached please find a scanned image of the report from the 1993 testing 

conducted on a Potline Scrubber Stack and a Potline Roof Monitor.

Thanks,

Thanks Henk, but I sent you a follow-up e-mail. I got the 3 page summaries but we need the whole 

report, not just the summary. Thanks

Rochelle,

This CBI data that you are referring to is the production data from the Potline fluoride emissions test reports that 

were provided during the February 2010 site visit. David Green from RTI has requested that we pull the 

production information from these reports so that he can reference the test data without compromising CBI. We 

are evaluating his request.

I thought I had send you the metals data. The two PDF files are attached, one for a Potline Scrubber stack and one 

for a Potline roof monitor. This data was collected in 1993 for use with permitting of and compliance with air 

toxics emissions under South Carolina Standard 8. The data is also used for use in the annual emissions inventory.

The roof monitor samples were collected via the Method 14 down comer and then collected isokinetically using 

the sampling apparatus and methodology described in EPA Method 0012 “Methodology for the Determination of 

Metals Emissions in Exhaust Gases from Hazardous Waste Incineration and Similar Combustion Processes.” 

The scrubber stack samples were collected isokinetically using the sampling apparatus and methodology described 

in EPA Method 0012 “Methodology for the Determination of Metals Emissions in Exhaust Gases from Hazardous 

Waste Incineration and Similar Combustion Processes.”

Regards,

Henk

Hello Henk. The data that you are sending CBI is this the production data related to the metals testing or 

is it some other testing that was done, because I have not received the Stack test report yet? Thanks
