The Outfall 001 samples for March 2. 3. 9, and 10 that were submitted to Simalabs International laboratory for BOD5 were held longer than the 48-hour maximum hold time, thereby invalidating those samples. The cause of this error was due to a misunderstanding by the Simalab analvst with regard to the BODE hold time requirement. who has subsequently been Instructed on these requlrements. The BOD5 results for those samples were: 03/02/01 = "estimated 123 mg/V: 03/03/01 =145 mg/L: 03/09/01 = 5.7 ma/L: and 03/10/01 = 5.3 mg/L.

The thermal/alkaline treatment system was shutdown on March 18, 2001. Therefore, the last HFA-hydrate and trifluoroacetate samples taken as a requirement of DWQ was at 0600 on March 19, 2001. The entry of "NF" indicates that there was "no flow" at Outfall 001 at the specified time, so no grab sample could be taken.

This report includes an additional DMR page for Outfall 001 to report the special monitored parameters required by the DWQ Fayetteville Regional Office. Four daily samples of Outfall 001 submitted for BOD5 analysis to our commercial laboratory (Simalabs International) were started well after the 48-hour maximum hold time. Those samples were for March 2 (Sample ID E10302), March 3 (ID E10303), March 9 (ID E10309), and March 10 (ID E 10310). This exceedance of the maximum hold time invalidates those analytical results for their use on the Discharge Monitoring Report. See the attached letter from Simalabs addressing this issue. If you have any questions regarding this matter, please feel free to call me at (910) 678-1155. Michael E.

April 24, 2001 Mr. Michael Johnson DuPont Fayetteville 22828 NC Hwy 87 West Fayetteville, NC 28306 Dear Mr. Johnson, On Monday, March 5, 2001 SIMALABS International picked up DuPont Fayetteville Works samples labeled E10302, I10302, E10303, and I10303 and carried these samples back to the lab for BOD 5-day analyses. On Monday, March 12, 2001 SIMALABS International picked up DuPont Fayetteville Works samples labeled E10309, I10309, E 10310, and 110310 and carried these samples to the lab for BOD 5-day analyses. BOD analyses must be started within 48 hours of collection, as required by Standard Methods for the Examination of Water and Wastes, 18"' Edition. Unfortunately, all eight of these samples were started outside of the 48-hour hold time. The North Carolina Division of Water Quality Laboratory Certification Section requires us to qualify these results as being analyzed outside of the regulatory hold times. Method hold times, particularly for non -chemically preserved samples should be met to ensure accurate measurements of parameters, as present when the sample was collected. Samples tested outside of the hold times may have their validity questioned. I am very sorry to report this lab error to you. I can assure that this issue was discussed in length and detail with the laboratory analysts and the problem should not reoccur. Your business is very important to us and we plan to work hard in the future to ensure your trust in our testing results. If I can be of any further assistance to you, please call me in my office at (336) 570-4661. :sincerely, qo7nSledge, II General Manager SIMALABS International WAY ? 2 2001 Fj V 1302 13elIll 0n[ St ITCt, Burlington.

This report includes an additional DMR page for Outfall 001 to report the special monitored parameters required by the DWQ Fayetteville Regional Office. Four daily samples of Outfall 001 submitted for BOD5 analysis to our commercial laboratory (Simalabs International) were started well after the 48-hour maximum hold time. Those samples were for March 2 (Sample ID E10302), March 3 (ID E10303), March 9 (ID E10309), and March 10 (ID E 10310). This exceedance of the maximum hold time invalidates those analytical results for their use on the Discharge Monitoring Report. See the attached letter from Simalabs addressing this issue. If you have any questions regarding this matter, please feel free to call me at (910) 678-1155. Michael E. Johnson Environmental Manager Enclosures cc: Mr. Paul Rawls, NCDENR DWQ, Fayetteville Regional Office Ms. Kitty Kramer, NCDENR DWQ, Fayetteville Regional Office E.

On Monday, March 12, 2001 SIMALABS International picked up DuPont Fayetteville Works samples labeled E10309,110309, E10310, and I10310 and carried these samples to the lab for BOD 5-day analyses. BOD analyses must be started within 48 hours of collection, as required by Standard Methods for the Examination of Water and Wastes, 186' Edition. Unfortunately, all eight of these samples were started outside of the 48-hour hold time. The North Carolina Division of Water Quality Laboratory Certification Section requires us to qualify these results as being analyzed outside of the regulatory hold times. Method hold times, particularly for non -chemically preserved samples should be met to ensure accurate measurements of parameters, as present when the sample was collected. Samples tested outside of the hold times may have their validity questioned. I am very sorry to report this lab error to you. I can assure that this issue was discussed in length and detail with the laboratory analysts and the problem should not reoccur. Your business is very important to us and we plan to work hard in the future to ensure your trust in our testing results.

The Outfall 001 samples for March 2, 3, 9, and 10 that were submitted to Simalabs International laboratory for BODE were held longer than the 48-hour maximum hold time, thereby Invalidating those samples. The cause of this error was due to a misunderstanding by the Simalab analyst with regard to the BODS hold time requirement, who has _subsequently been Instructed on these requirements. The BODE results for those samples were: 03/02/01 = "estimated 123 ma/L": 03/03/01 =145 mo/L! 03/02/01 = 5.7 me/L! and 02/10/01 = 5.2 mn/L- "I certify, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

The thermal/alkaline treatment system was shutdown on March 18, 2001. Therefore, the last HFA-hydrate and trifluoroacetate samples taken as a requirement of DWO was at 0600 on March 19, 2001. The entry of "NF" Indicates that there was "no flow" at Outfall 001 at the specified time, so no arab sample could be taken.
