RALEIGH
SPRAY IRRIGATION SYSTEM PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina
as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
The Town of Conway
Northampton County
FOR THE
continued operation of approximately 500 linear feet of 8 inch and 10 inch gravity sewer, a 260 GPM
pump station, and approximately 2,500 linear feet of 6 inch force main, a 0.15 MGD wastewater treatment
facility consisting of a 65 day storage/treatment lagoon, a gaseous chlorinator, a 600 GPM spray irrigation
pump station with approximately 18.5 acres of irrigation fields and three (3) groundwater monitoring wells
to serve the' Town of Conway Wastewater Treatment Plant with no discharge of wastes to the surface
waters, pursuant to the application received August 31, 1993 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 September 30, 1998, shall void Permit
No. WQ0001284 issued April 4, 1989, and shall be subject to the following specified conditions and
limitations:
I. PERFQRMANCE STANDARDS
1. 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 waterAhich
will render them unsatisfactory for normal use. In the event that the facilities.ail to.
perform satisfactorily, including the creation of nuisance conditions or fa�urecqr the
irrigation area to adequately absorb the wastewater, the Permittee shall take sucH imrKdiate
corrective action to correct the problem, including actions as may be required Ty the
Division of Environmental Management.
>
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 sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.

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,
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 a permit
modification.

treatment facilities by the Certification Comir�ission. The Permittee must also employ a
certified back-up operator of the appropriate type and grade to comply with the conditions
of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and

GROUNDWATER REQUIREMENTS
The three (3) existing monitor wells (MW's 1,2,3) shall be sampled every February, June,
and September for the following parameters:
NO3
NO2
'IDS
PH
Chloride
Volatile Organic Compounds -
Total Ammonia
Fecal Coliform
TOC
Water Level �3
r,
In February only (by Method 1 or�'Method 2
below)
�_'
Method l: Method 6230D (Capillary - Column), "Standard MetWds or the
Examination of Water and Wastewater", 17th edition, 1959 ;
C!

Method 2: Method 502.2 " Methods for the Determination of Organic Compounds
in Drinking Water", U.S. EPA - 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 monitoring 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 6230D, or the equivalent method
502.2, then EPA methods 604 and 611 must also be run 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 P.O. Box 29535 Raleigh, NC 27626-0535 on Form GW-59
(Compliance Monitoring Report Form) every March, July, and October.
2. The Compliance Boundary for the disposal system is specified by regulations in 15 NCAC
2L, Groundwater Classifications and Standards. The compliance boundary is established
at either (1) 500 feet from the waste disposal area, or (2) the property boundary, whichever
is closest to the waste disposal area. An exceedance of the 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 143-215.6(1)a.
Also in accordance with 15A NCAC 2L, a Review Boundary is established around
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 permitee.
3. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
V . INSPECTIONS

1. Adequate inspection, maintenance, and cleaning shall be provided by the Pirmftite to
insure proper operation of the subject facilities.
