The workshop was attended by all production personnel; the workshop agenda is attached. Quantitative monitoring was conducted on February 9 2010. Both the laboratory analysis report and the completed NCDFNR Discharge Outfall Monitoring Report form are tiled in Appendix F of the SWPPP notebook. All required copies were submitted to Central Files in February; additional copies are attached for your review. General Permit NCG140000 does not require semi-annual quantitative monitoring. It does require semi-annual qualitative monitoring which has been completed at the subject facility by this consultant. The next quantitative monitoring event will occur during the first quarter of 2011 as suggested by the extended General Permit NCG140000. We appreciate this opportunity to respond to your concerns. In the meantime, if you have any questions, do not hesitate to call. Sincerely, ST WATER SERVICES GROUP, LLC ames D. Frei Senior Project Manager RECEIVED Attachments. NOV " 2 NA cc: A.

RE: Notice of Violation Powell Ready Mixed Concrete Permit No. NCG140332 Dear'Mr. Schuster: 1251-6 Trillium Circle } .. Raleigh, North Carolina 27606 Phone i 919.816.0591 Fax: 919.816.0661 - Is 11 L (j �n 4 U 'JAN - 5 2005 In regards to your NOV letter dated December 29, 2004, I believe an error has been made by NCDENR-DWQ. Your letter indicates that the limit violation was of a Process Wastewater Discharge: Powell Ready Mixed Concrete does not generate nor discharge Process Wastewater at this site. The discharge monitoring report form submitted to NCDENR-DWQ (see attached copy) is for a stormwater discharge sample. According to NPDES General Permit NCG140000 Part 11 Section B.1. Table 2, the TSS cut-off limit is 100 mg/L for stormwater discharges. The Permittee understands that the cut-off limit is not a not -to -exceed -limit, and therefore cannot be violated. The cut-off value provides guidance in accessing the effectiveness of implemented BMPs and the need to improve certain BMPs. The Permittee will collect a stormwater discharge sample during Calendar Year 2005 as required by the Permit, and will continue to implement appropriate TSS-reducing BMPs. We request that NCDENR-DWQ withdraw this Notice of Violation as no violation has occurred. In the meantime, if you have any questions, do not hesitate to call.
