Prior to the initiation of these connection activities, appropriate Division approval shall be received. WQ0009772 Version 2.5 Shell Version 141027 Page 2 of 1 1 H. PERFORMANCE STANDARDS I. The subject non -discharge facilities shall be effectively maintained and operated at all times so there is no discharge to surface waters, nor any contravention of groundwater or surface water standards. In the event the facilities fail to perform satisfactorily, including the creation of nuisance conditions due to improper operation and maintenance, or failure of the infiltration areas to adequately assimilate the effluent, the Permittee shall take immediate corrective actions including Division required actions, such as the construction of additional or replacement wastewater treatment or infiltration facilities. 2_ This permit shall not relieve the Permittee of their responsibility for damages to groundwater or surface water resulting from the operation of this facility. 3. All wells constructed for purposes of groundwater monitoring shall be constructed in accordance with 15A NCAC 02C .0108 (Standards of Construction for Wells Other than Water Supply), and any other jurisdictional laws and regulations pertaining to well construction. 4. Effluent quality shall not exceed the limitations specified in Attachment A_ 5. AppIication rates, whether hydraulic, nutrient or other pollutant, shall not exceed those specified in Attachment B. 6. A usable green area shall be maintained for effluent disposal. The green area shall have the capability of accommodating the facility's average daily flow without exceeding the green area loading rates. As defined in 15A NCAC 02H .0404(g)(7), a "green area" is an area suitable for waste disposal, either in its natural state or which has been modified by planting a vegetative cover of grasses or Iow growing shrubbery. 7. The compliance boundary for the disposal system shall be specified in accordance with 15A NCAC 02L .0107(b). This disposal system was individually permitted on or after December 30, 1983; therefore, the compliance boundary is established at either 250 feet from the effluent disposal area, or 50 feet within the property boundary, whichever is closest to the effluent disposal area. An exceedance of groundwater standards at or beyond the compliance boundary is subject to remediation action according to 15A NCAC 02L .0106(d)(2) as well as enforcement actions in accordance with North Carolina General Statute 143-215.6A through 143-215.6C. 8. In accordance with 15A NCAC 02L .0108, the review boundary is established midway between the compliance boundary and the effluent disposal area. Any exceedance of groundwater standards at the review boundary shall require action in accordance with 1 SA NCAC 02L .0106. 9. The Permittee shall apply for a permit modification to establish a new compliance boundary prior to any sale or transfer of property affecting a compliance boundary. 10_ In accordance with 15A NCAC 02L .0107(d), no wells, excluding Division approved monitoring wells, shall be constructed within the compliance boundary except as provided for in 15A NCAC 02L .0107(g). WQ0009772 Version 2.5 Shell Version 141027 Page 3 of 11 11. In accordance with 15A NCAC 02L .0107(f), except as provided for in 15A NCAC 02L .0107(g), for all permits issued or reissued after January 1, 1993 and the Permittee is not the owner of the land within the compliance boundary, it shall be a condition of this permit that the landowner of the land within the compliance boundary, if other than the Permittee, execute and file in the Register of Deeds in the county in which the land is located, an easement running with the land which: a. Contains either a notice of the permit, including the permit number, a description of the type of permit, and the name, address and telephone number of the permitting agency; or a reference to a notice of the permit with book and page number of its recordation if such notice is required to be filed by statute.- b. Prohibits the construction and operation of water supply wells within the compliance boundary; and c. Reserves the right to the Permittee and the State to enter on such property within the compliance boundary for groundwater monitoring and remediation purposes_ The easement may be terminated by the Director when its purpose has been fulfilled or the need for the easement no longer exists. Under those conditions the Director shall, upon request by the landowner, file a document terminating the easement with the appropriate Register of Deeds. 12. The facilities permitted herein shall be constructed according to the following setbacks: a.

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 he surveyed relative to a common datum. 4, Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods: a. Standard Method 6230D, PQL at 0.5 µg/L or less b. Standard Method 6210D, PQL at 0.5 µg/L or less C. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less d. EPA Method 8260, Low Concentration, PQL at 0.5 µg/L or less e. Another method with prior approval by the Water Quality Permitting Section Chief Any method used must meet the following qualifications: a. A laboratory must be DWR certified to run any method used. b. The method used must, at a minimum, include all the constituents listed in Table VIII 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 DWR. Any constituents detected above the MDL but below the PQL of 0.5 µg/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 supervisor, telephone number (252) 946-6481, must be contacted immediately for further instructions regarding any additional follow-up analyses required. 6. If TOG concentrations greater than 10 mg/L 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 rng/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.
