VI. GENERAL CONDMONS Failure to abide by the conditions and limitations contained in this permit may subject the Permittee to an enforcement action by the Division in accordance with North Carolina General Statute 143- 215.6A to 143-215.6C. 2. This permit shall become voidable unless the facilities are constructed in accordance with the conditions of this permit, the approved plans and specifications, and other supporting data. WQ32930 Version 1.1 Shell Version 080229 Page 8 of 10 3. This permit is effective only with respect to the nature and volume of wastes described in the application and other supporting data. No variances to applicable rules governing the construction and / or operation of the permitted facilities are granted unless specifically requested and granted in this permit. 4. The Division accepts the data -based design flow rate of 6.8 gallons per day per student (GPD/student) for the community served by this system. Regardless of the adjusted design daily wastewater flow rate, at no time shall the wastewater flows exceed the limits defined in this permit for the subject facility or exceed the capacity of the sewers downstream of any new sewer extension or service connection(s). The Permittee shall report the actual (measured) monthly average amount of wastewater now contributed per unit (GPD/student) for the 12 months prior to renewal. If any of these values are within 1.4 GPD/student (20% of the approved value), the permittee shall re-evaluate the approved value using the methodology used to determine the approved flow rate of 6.8 GPD/student and submit this information within eighteen months of renewal. The Division may change the design flow rate for connections to the system at that time, and upon each renewal cycle, pending an evaluation of the submitted flow information. The issuance of this permit does not exempt the Permittee from complying with any and all statutes, rules, regulations, or ordinances, which may be imposed by other government agencies (local, state, and federal) that have jurisdiction. Of particular concern to the Division are applicable river buffer rules in 15A NCAC 02B .0200, erosion and sedimentation control requirements in 15A NCAC Chapter 4 and under the Division's General Permit NCG010000, and any requirements pertaining to wetlands under 15A NCAC 02B .0200 and 02H .0500. 6.

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. c. 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. d. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods: I. Standard Method 6230D, PQL at 0.5 µg/L or less 2. Standard Method 621 OD, PQL at 0.5 µg/L or less 3. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less 4. EPA Method 8260, Low Concentration, PQL at 0.5 pg/L or less 5_ Another method with prior approval by the Aquifer Protection Section Chief Any method used must meet the following qualifications: a. A laboratory must be DWQ certified to run any method used. b. The method used must- at a minimum, include all the constituents listed in Table Vlll of Standard Method 6230D. c. The method used must provide a PQL of 0.5 µg/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 µg/L must be qualified (estimated) and reported. e. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C. then the Wilmington Regional Office Aquifer Protection Supervisor, telephone number (910) 796-7215, must be contacted immediately for further instructions regarding any additional follow-up analyses required. If TOC concentrations greater than 10 mg/l are detected in any downgradient monitoring well, additional sampling mud analysis must be conducted to identify the individual constituents comprising this TUC 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 acid analysis as described above. g. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 1 and this attachment.
