the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.

3. The spray irrigation facilities shall be effectively maintained and operated at all times so that
there is no discharge to the surface waters, nor any contamination of ground waters which
will render them unsatisfactory for normal use. In the event that the facilities fail to
perform satisfactorily, including the creation of nuisance conditions or failure of the
irrigation area to adequately assimilate the wastewater, the Permittee shall take immediate
corrective actions including those actions that may be required by the Division of
Environmental Management, such as the construction of additional or replacement
wastewater treatment and disposal facilities.
4. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
5. The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.
6. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
7. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or,places of public assembly under
separate ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between wastewater treatment units and wells, and
g) 50 feet between wastewater treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for
this waste treatment and disposal system. These buffers are not intended to prohibit or
prevent modifications, which are required by the Division, to improve performance of the
existing treatment facility. These buffers do, however, apply to unconstructed facilities or
to modifications of the treatment and disposal facilities which are for the purpose of
increasing the flow that is tributary to the facility. These buffers do apply to any expansion
or modification of the spray irrigation areas and apply in instances in which the sale of
property would cause any of the buffers now complied with, for the treatment and disposal
facilities, to be violated. The applicant is advised that any modifications to the existing
facilities will require a permit modification.

2. The six (6) monitor wells must be sampled initially after construction and thereafter every
March, July andNovember for the following parameters:
NO3
TOC
Ammonia Nitrogen
Water Level
Total Suspended Solids
Volatile Organic Compounds -
TDS
pH
Chloride
Fecal Coliforms
In November only (by Method 1 or Method 2 below)
Method 1: Method 6230D (Capillary - Column), "Standard Methods for the
Examination of Water and Wastewater", 17th edition, 1989
Method 2: Method 502.2 "Methods for the Determination of Organic Compounds in
Drinking Water", United States Environmental Protection Agency - 600/4-
88/039
The measurement of water level must be made prior to sampling for the remaining
parameters. The depth of water in each well shall be measured from the surveyed point on
the top of the casing.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide relative elevations of the measuring point for each monitor well.
If TOC 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 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.
If any volatile organic compounds are detected by method 6234D, or the equivalent method
502.2, then EPA methods 604 and 611 must also be ran to detect other organic compounds
which may be present. The results of all analysis specified in the monitoring requirements,
including 604 and 611 if required, must be submitted simultaneously.
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management Post Office Box 29535 Raleigh, N.C. 27626-0535 on Form
GW -59 (Compliance Monitoring Report Form) every April, August and December.
3. The Com liance BoundM for the disposal system is specified by regulations in 15 NCAC
2L, Groundwater Classifications and Standards. The Compliance Boundary is established
at either (1) 250 feet from the waste disposal area, or (2) 50 feet within the property
boundary, whichever is closet to the waste disposal area. An exceedance of Groundwater
Quality Standards at or beyond the Compliance Boundary is subject to immediate
remediation action on addition to the penalty provisions applicable under General Statute
143-215.6A(a)(1).
Also in accordance with 15A NCAC 2L, a REVIEW BOUNDARY, delineated on the
attached site map, is established around the disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. Any exceedance of
standards at the Review Boundary shall require remediation action on the part of the
permittee.
