Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Coleen H. Sullins, Director Division of Water Quality Subject: Permit No. WQ0007144 Correction Camp Seafarer Wastewater Surface Irrigation Pamlico County In accordance with a notification from Mr. William Hart (Washington Regional Office-DWQ/APS) received on November 6, 2007, we are forwarding herewith the corrected Attachment C of Permit No. WQ0007144, issued July 27, 2007, for the subject facility. The following corrections have been made to the permit: 1. The groundwater monitoring well MW-1 was abandoned a few years ago, therefore, is being removed from the permit. 2. The groundwater monitoring well MW-7 and MW-8 have been installed, therefore, are being added to the permit. Please replace Attachment C with the corrected Attachment C into Permit No. WQ0007144, issued July 27, 2007. If you have any questions regarding this request, please do not hesitate to contact Chonticha McDaniel at (919) 715-6188. Thank you for your cooperation. Coleen H.

The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measurement of pH shall be made after purging and prior to sampling for the remaining parameters. 3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top of casing) of all monitoring wells shall be surveyed relative to a common datum. 111nnnn7IQQ„n7n777 Attachment Page I of 4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods: (A) Standard Method 6230D, PQL at 0.5 ug/L or less (B) Standard Method 6210D, PQL at 0.5 ug/L or less (C) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or less (D) EPA Method 8260, Low Concentration, PQL at 0.5 ug/L or less (E) Another method with prior approval by the Aquifer Protection Section Chief Any method used must meet the following qualifications: (1) A laboratory must be DWQ certified to run any method used. (2) The method used must, at a minimum, include all the constituents listed in Table VIII of Standard Method 6230D. (3) The method used must provide a PQL of 0.5 ug/L or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents detected above the MDL but below the PQL of 0.5 ug/L must be qualified (estimated) and reported. 5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, 'then the Washington. Regional Office Aquifer Protection Supervisor, telephone number (252) 946-6481, must be contacted immediately for further instructions regarding any additional follow-up analyses required. If TOC concentrations greater than 10 mg/I are detected in any downgradient monitoring well, additional sampling and analysis must be conducted - to identify the individual constituents comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/l, this concentration will be taken, to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above. 7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 2, 3, and this attachment. WQ0007I44p070727 Attachment C Page 2 of 2
