PERMISSION IS HEREBY GRANTED TO
Town of Pikeville
Wayne County
FOR THE
continued operation of a 0.099 MGD spray irrigation treatment and disposal facility consisting of two
lagoons with reserve storage capacity, post chlorination facilities, flow measuring, dual 80 GPM irrigation
pumps, approximately 11,150 linear feet of spray irrigation laterals, approximately 19 acres of spray area,
and all associated piping, valves, controls, spray heads, and appurtenances to serve the Town of Pikeville
with no discharge of wastes to the surface waters, pursuant to the application received January 10, 1997,
and in conformity with the project plan, specifications, and other supporting data subsequently filed and
approved by the Department of Environment, Health and Natural Resources and considered a part of this
permit.
This permit shall be effective from the date of issuance until March 31, 2002, shall void Permit
No. WQ0004898 issued October 30, 1992, and shall be subject to the following specified conditions and
Iimitations:
I. PERFORMANCE STANDARDS
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 Water Quality, such
as the construction of additional or replacement wastewater treatment and disposal facilities.
2. 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.
3. 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
Water Quality.
4. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.

5 . 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 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 apermit
modification.
11. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.

IV. GROUNDWATER REQUIREMENTS
Within sixty (60) days of permit reissuance, monitoring well MW-2 and MW-4 shall be
abandoned according to 15A NCAC 2C .0113 (Abandonment of Wells) in the 15A NCAC
2C .0100 Well Construction Standards.
2. Monitor wells MWA and MW-3 shall be sampled every April, August, and December for
the following parameters:
Nitrate (NO3-N)
Total Dissolved solids (TDS)
pH
Chloride
Total Ammonia
Total Organic Carbon (TOC)
Water Level
Fecal Coliforms
The measurement of water levels must be made prior to sampling for the remaining
parameters. The depth to 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 the relative elevation of the measuring point for each monitoring well.
If TOC concentrations greater than 10 mg/I 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/1, 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.
4

The results of the sampling and analysis must be received on Form GW-59 (Groundwater
Quality Monitoring: Compliance Report Form) by the Groundwater Section, Permits and
Compliance Unit, P.O. Box 29578 Raleigh, N.C. 27626-0578 on or before the last

500 feet from the waste disposal area, or (2) at the property boundary, whichever is closest
to the waste disposal area. An exceedance of Groundwater Quality Standards at or beyond
the Compliance Boundary is subject to immediate remediation action in addition to the
penalty provisions applicable under General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY 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.
V . INSPECTIONS
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal facilities
