David,

Our test consultant confirmed that there was in fac t a typo in the entry for Total Hexa-CBs. The value in the Table 3Ap. 2 of 3

should be 1.79E-03, not the 1.79E+03. We will send a corrected version of the report.

Thanks for bringing this to our attention.

for ICR

Mr. Parent,

My contractor and I have been reviewing the test re port for the Massena East facility and have come across what appears to be simply a typo (wrong units used). Specificall y, if you look at Table 3A of the report (summary of PCB analyses for Run 1 on the South Scrubber - found on page 23 of 181 in the pdf file) you see that Total Hexa-CBs are re ported at 1,790 ug resulting in an emission rate of 0.109 lb per ton of aluminum for this pollutant. However, the la b data
sheet for this same test run indicates Total Hexa-C Bs at 0.00179 ug (see page 142 of 181 in the pdf file) wh ich would presumably result in an emission rate of 1.09 E-07 lb per ton for this pollutant.

Perhaps not such a big deal since it does not affec t the toxic equivalencies, but please keep in mind that t hep. 3 of 3

emission report will eventually go into the docket. If you want to send me a revised emission report with a co rrected Table 3A I would be happy to use the revised report for the
docket.

I also want to let you know that we have not finish ed reviewing the report yet, and we may have other que stions in the future. We are trying to resolve questions as we find them instead of holding them until the end.
