Terri, 

Thank you for submitting the additional information. As you know, we are are trying to determine a 

conservative analytical concentration of NMP in the waste samples. I feel we have exhausted our review 

of the NMP analysis and at this point we will require one last calculation submittal from the laboratory . We 

found that there is evidence that the chromatographic peak just before the first internal standard may be a 

derivative of the NMP analyte. Can you have the laboratory integrate this peak (approximately retention 

time 7.825 min.) for all four of the composite samples. Please submit these calculations in the same 

format as the last submission. 

• 

It looks like this may double the concentration of NMP in the samples but that these results will still be well 

below the DRAS limits. 

Please let me know if you have any questions. 

-Chris

Rick, 

Thanks for this data. One last request, can you send me the same chromatogram 

and ion abundance scans for sample 1003151-03, peaks at RT 

7.82 and RT 8.42 minutes? Thanks.
