Unless the Division Director grants a variance, expansion of the facilities permitted herein shall not occur if any of the following apply: a. The Permittee or any parent, subsidiary, or other affiliate of the Permittee has been convicted of environmental crimes under G.S. 143-215.613, or under Federal law that would otherwise be prosecuted under G.S. 143-215.613, and all appeals of this conviction have been abandoned or exhausted. b. The Permittee or any parent, subsidiary, or other affiliate of the Permittee has previously abandoned a wastewater treatment facility without properly closing the facility. c. The Permittee or any parent, subsidiary, or other affiliate of the Permittee has not paid a civil penalty, and all appeals of this penalty have been abandoned or exhausted. d.

The Division accepts the data -based design flow rate of 240 gallons per day per home (GPD/home) for the users served by this facility. At no time shall wastewater flows exceed the limits defined in this permit, or exceed the sewer capacity downstream of any new sewer extension or service connection. The Permittee shall report the measured monthly average amount of wastewater flow contributed per unit (GPD/home) for the 12 months prior to permit renewal. If any of these monthly averages are within 20% of the approved value, the Permittee shall reevaluate the approved value using the methodology applied to determine the approved flow rate of 240 GPD/home, and submit this information with the renewal application for reevaluation of the approve flow rate. [15A NCAC 02T .0114(f)] 12. The Permittee shall retain the Division's written approval of the authorized adjusted daily design flow rate for the life of this facility, and shall transfer this approval to any future Permittee.

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. 4. Volatile Organic Compounds (VOC) - In December only, analyze by one of the following methods: a. Standard Method 6230D, PQL at 0.5 gg/L or less b. Standard Method 6210D, PQL at 0.5 �tg/L or less c. EPA Method 8021, Low Concentration, PQL at 0.5 gg/L or less d. EPA Method 8260, Low Concentration, PQL at 0.5 gg/L or less e. Another method with prior approval by the Water Quality Permitting Section Chief Any method used shall meet the following qualifications: a. A laboratory shall be DWR certified to run any method used. b. The method used shall include all the constituents listed in Table VIII of Standard Method 6230D. c. The method used shall provide a PQL of 0.5 �tg/L or less that shall be supported by laboratory proficiency studies as required by the DWR Laboratory Certification Unit. Any constituents detected above the MDL but below the PQL of 0.5 gg/L shall 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 Raleigh Regional Office supervisor, telephone number (919) 791-4200, shall be contacted immediately for further instructions regarding any additional follow-up analyses required. 6. If TOC concentrations greater than 10 mg/L are detected in any downgradient monitoring well, additional sampling and analysis shall 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 1 and this attachment. WQ0021934 Version 4.0 Attachment C Page 1 of 1 vorp ve,
