H. PERFORMANCE STANDARDS
1. 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 disposal 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 limitations shall not exceed those specified in Attachment A.
5. Application 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 low
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 15ANCAC 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
A 107(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 Dare
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.

1. 3 x Year monitoring shall he conducted in March, July & November: Annual monitoring shall be conducted every November.
2. 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 p11 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 veils shall be surveyed relative to a common datum.
Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods:
a_ Standard Method 6230D. PQI, at 0.5 pg/I, or less
b. Standard Method 62101), PQL at 0.5 ltg/L or less
c. EPA Method 8021. Low Concentration. PQI, at 0.5 pg/I, or less
d. EPA Method 8260, Low Concentration. PQL at 0.5 pg/L or less
e. 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 VIII of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 pg/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 belo%v the PQL of 0.5 lrg/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 [phone], shall be contacted immediately for further instructions regarding any additional follow-up analyses required.
If TOC concentrations greater than 10 mg/1 are detected in any downgradient monitoring well, additional sampling and analysis most be conducted to identify the individual constituents
domprising this TOC concentration_ If the TOC concentration as treasured in the background monitor well exceeds 10 mg/l, this concentration will be taken to represent the naturally occurring
TOC concentration. Any exceedarrces 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 I and this attachment.
