H.
L Within sixty (60) days of permit issuance, the permittee shall submit two original copies of a scaled
site map (scale no greater than 1 '=100'); however, special provisions may be granted upon prior
approval for large properties. The map(s) must include the following information:
a. The location and identity of each monitoring well.
b. The location of major components of the waste disposal system.
c. The location of property boundaries within 500 feet of the disposal area(s).
d. The latitude and longitude of the established horizontal control monument.
c. The elevation of the top of the well casing (which shall be known as the "measuring point")
relative to a common datum.
f. The depth of water below the measuring point at the time the measuring point is established.
g. The location of review and compliance boundaries.
h. The date the map is prepared and/or revised.
Control monuments shall be installed in such a manner and made of such materials that the
monument will not be destroyed due to activities that may take place on the property. The maps and
any supporting documentation shall be sent to the N.C. Division of Water Quality, Aquifer Protection
Section, 1636 Mail Service Center, Raleigh, N.C. 27699-1636. The permittee is responsible for the
geographic accuracy of any map submitted, however produced.
2. If not already installed, waste -level gauges, to monitor waste levels in each of the two infiltration
basins, shall be installed within 60 days of issuance of this permit / prior to operation.
No later than six (6) months prior to the expiration of this permit, the Permittee shall request renewal
of this permit on official Division form(s), Upon receipt of the request, the Division will review the
adequacy of the facilities described therein, and if warranted, will extend the permit for such period of
time and under such conditions and limitations as it may deem appropriate. Please note that Rule
15A NCAC 02T .0105(d) requires an updated site map to be submitted with the permit renewal
application.
4. The subject wastewater treatment and disposal facilities shall be connected to an operational publicly
owned wastewater collection system within 180 days of its availability to the subject facilities, if the
subject wastewater treatment or disposal facilities are in noncompliance with the terms and conditions
of this non -discharge permit or the governing statutes or regulations. Prior to the initiation of these
connection activities, appropriate approval must be received from this Division.
PERFORMANCE STANDARDS
The surface infiltration facilities shall be effectively maintained and operated at all times so that there
is no discharge to the surface waters, nor any contravention of groundwater or surface water
standards. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions or failure of the infiltration

2. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be rescinded
unless the facilities are installed, maintained, and operate in a manner which will protect the assigned water
quality standards of the surface waters and ground waters. The ponding of wastewater on the surface of the
distribution field when the dosing cycle commences shall be considered as evidence of failure of the soils to
adequately assimilate the wastewater. Additionally, such failure shall be interpreted as a violation of this
permit condition.

1. 3 X/year monitoring shall be conducted in April, August and 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 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. If TOG concentrations greater than 10 mgll are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify
the individual constituents comprising this TOG concentration. If the TOG concentration as measured in the background monitor well exceeds 10 mgll, this
concentration will be taken to represent the naturally occurring TOG concentration. Any exceedances of this naturally occurring TOG concentration
in the downgradient wells shall be subject to the additional sampling and analysis as described above.
5. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 2 and this attachment.
