PERFORMANCE STANDARDS 1. The subject non -discharge facilities shall be effectively maintained and operated at all tinges 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 irrigation 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 irrigation facilities. 2. This permit shall not relieve the Permittce of their responsibility for damages to groundwater or surface water resulting from the operation of this facility. 3. AlI 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.

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 low growing shrubbery. 7. The compliance boundary for the disposal system shall be specified in accordance with ISA 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 15A 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). 11. Except as provided for in 15A NCAC 02L .0107(g), the Permittee shall ensure any landowner who is not the Permittee and owns land within the compliance boundary shall execute and file with the Carteret County Register of Deeds an easement running with the land containing the following items: a. A notice of the permit and number or other description as allowed in 15A NCAC 02L .0107(f)(1); b. Prohibits construction and operation of water supply wells within the compliance boundary; and c. Reserves the right of the Permittee or the State to enter the property within the compliance boundary for purposes related to the permit. The Director may terminate the easement when its purpose has been fulfilled or is no longer needed. WQ0005233 Version 4.0 Shell Version 140324 Page 2 of 8 12.
