Subject: 
Coke Ovens - DLL designation for rows 969-1049

Hello,

We have reviewed the AM-Burnsharbor-IN Coke Battery No. 2 Underfire Stack SW846 Method 0031 data in rows 969-1049 that the COETF commented: 
"Basis for EPA-assigned DLL run flag designation unclear - stack test report indicates BDL (<); emission rate should be one-half listed value (see A-1.Air Stack Tests worksheet)"

The DLL flag came from the Industry provided file "U2 UF ERT.xlsx", tab `(6) Speciated Manual Data (2)'.
Please see attached file:
U2 UF ERT.xlsx

We also reviewed the "AMBH UNDERFIRE stack test report m162810b.pdf" file and found that the summary tables in pdf pages 22-24 do have a "<" next to each run and pollutant; however, the laboratory section in pdf pages 99-106 show the different sorbent tube fractions analyzed where some have a "<" symbol and some do not. The mix of BDL and ADL fractions results in the DLL designation for the run. 
Please see attached file:
-Pages from AMBH UNDERFIRE stack test report m162810b-2.pdf (summary tables in pdf pages 22-24 and laboratory section in pdf pages 99-106)

We are still reviewing the comments regarding DLL designation for the other rows identified in the COETF review comment file. 

We will add those responses along with the rest of the other responses to a copy of the COETF review comment file to be sent back to COETF once all comments are addressed.

Please let us know if there are any questions.
Thank you,
Gabrielle
