Keith,

Based on the revised table, the percent of THC represented by the listed 

organic HAP is 35%.

The previous table was revised with the following changes:

-“BDL” was replaced by the reported detection limits.

-Added one additional row of data for Ash Grove, Montana.

-Revised some of the previous concentrations after QA of the conversions 

(from the Test Data Details tab).

Also, note the following:

-the THC concentrations for Ash Grove Seattle (38.87) and Ash Grove 

Durkee (30.84) are from different test reports than those containing the 

organic HAP results. Is that a problem?

-phenol and hexane results are all BDL – indicates there is not much 

there; they could be dropped.

-Naphthalene detection limits are very high for 3 out of 5 kilns.

Keith,

I compiled all the organic HAP test data I could find that we got with 

the 

114 ICR responses. In most of the cases, I was able to convert the data 

to 

ppmvd@7%O2. I ended up with about 15 useable data sets. In some cases, 

only one organic HAP was reported, but in others several organic HAP were 

measured. Where they also reported THC, I included that. I incorporated 

these data into the table we have that summarizes the THC test data. In 

just a couple of instances did I find organic HAP data for kilns in our 

THC data sets. I was able to calculate the HAP concentration as a 

percentage of THC for 5 sets of data (two tests were for the same kiln, 

but the results of the two tests were quite different, so I kept them 

separate for now). Lots of the totals are below 5 ppm, with the average 

being 3.4. The average percentage of THC that is HAP is 24%, pretty close 

to the earlier report of 23%.
