EDEHNR
Subject: Permit No. WQ0003299
Town of Seaboard
Wastewater Treatment and
Spray Irrigation Disposal
Northampton County
In accordance with your application received November 14, 1994, we are forwarding herewith
Permit No. WQ0003299 dated April 13, 1995, to the Town of Seaboard for the continued operation of the
subject wastewater treatment and spray irrigation facilities. The Division's Raleigh Regional Office reports
the spray irrigation fields are still experiencing problems with runoff at several locations. The Division's
Groundwater Section reports exceedances of nitrate, TDS, and chlorides in groundwater monitoring data,
which may be attributable to overloading the spray irrigation fields and possibly the location of monitoring
wells. A moratorium against the addition of wastewater flow to this facility has been in effect for a year
and a half. At this time, the Town and the Division are negotiating a Special Order by Consent (SOC),
which may require additional treatment facilities, additional spray fields, and/or upgrades and repairs to the
Town's sewer collection system to reduce infiltration and inflow (I/I). If this becomes the case, the Town
will be required to submit a request for modification of this permit. The Town of Seaboard is required to
take all necessary action to meet and maintain the limits and standards required by this permit.
This permit shall be effective from the date of issuance until March 31, 2000, shall void Permit
No. WQ0003299 issued January 14, 1994, and shall be subject to the conditions and limitations as
specified therein. Please pay particular attention to the monitoring requirements in this permit. Failure to
establish an adequate system for collecting and -maintaining the required operational information will result
in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150E of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer
27447, Raleigh, NC 27611-7447. Unless such demands are made this permit shall be final and binding.

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
Town of Seaboard
Northampton County
FOR THE
continued operation of approximately 2,825 lineal feet of 10 inch sewer lines and a 72,000 GPD spray
irrigation treatment and disposal facility consisting of a bar screen, a flow meter, two (2) 1.5 acre
stabilization lagoons in series, chlorination facilities, a 1.5 million gallon holding basin, dual 260 GPM
irrigation pumps, approximately 12 acres of grassed land spray irrigation fields with associated piping,
irrigation fixtures, monitoring wells, laboratory facilities, and appurtenances to serve the Town of
Seaboard with no discharge of wastes to the surface waters, pursuant to the application received
November 14, 1994, 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, 2000, shall void Permit
No. WQ0003299 issued January 14, 1994, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. The spray irrigation facilitie$ 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.
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
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, 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 a permit
modification.
11. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of
the wastewater treatment facilities. The operator must hold a certificate of the type and
grade at least equivalent to or greater than the classification assigned to the wastewater
treatment facilities by the Certification Commission. 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 11, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter 8A, .0202.
3. A suitable vegetative cover over the spray fields and where needed to control erosion and
structural integrity shall be maintained. _r
4. Irrigation shall not be performed during inclement weather or when the ground is in a
condition that will cause runoff.
5. Adequate measures shall be taken to prevent wastewater runoff from the
spray fields.
6. The facilities shall be effectively maintained and operated as a non -
discharge system to prevent the discharge of any wastewater resulting from
the operation of this facility.
7. The application rate shall not exceed 104 inches per year at an instantaneous application rate
not to allow any runoff.
8. No type of wastewater other than that from the Town of Seaboard shall be sprayed onto the
irrigation area.

9. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
10. Public access to the land application sites shall be controlled during active site use. Such
controls may include the posting of signs showing the activities being conducted at each
site.
11. Freeboard in the treatment lagoons and the storage basin shall not be less than two feet at
any time.
III. MONITORINGMONITORUNG AND REPORTING REQUIREMENTS

IV, GROUNDWATER REQUIREMENTS
1. Monitoring Wells MW-1, 3, and 4 shall be abandoned in accordance with 15A NCAC 2C
(Well Construction Standards).
2. Within 90 days of permit issuance,the permittee shall construct three replacement
monitoring wells (designated as MW-la, 3a, and 4a) at the review boundary. The well(s)
shall be constructed such that the water level in the well is never above or below the
screened (open.) portion of the well at any time during the year. The exact location for each
well shall be determined by the Raleigh Regional Office. Each monitoring well shall be
located at the review boundary, constructed in accordance with this permit, and approved
by the Raleigh Regional Office.
3. Monitor wells MW-1a, MW-2, MW-3a, MW-4a, and MW-5 shall be sampled every
March, July, and November for the following parameters:: --
Nitrates Total Ammonia
Nitrites TOC
pH Water Level
Chloride Fecal Coliforms
Total Dissolved Solids
Volatile Organic Compounds - In November only (by Method 1 or 2 below)
Method 1: Method 6230D (Capillary - Column), "Standard Methods For The
Examination of Water and Wastewater", 17th ed., 1989
Method 2: Method 502.2 "Methods For The Determination Of Organic Compounds
In Drinking Water", U.S. EPA-600/4-88/039
4

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/1 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 the Raleigh Regional Office Groundwater Supervisor, telephone number 919/
571-4700 must be contacted immediately for further instructions regarding any additional
follow-up analyses required. The results of all initial and follow-up analyses must be
submitted simultaneously.
The results of the sampling and analysis shall be sent to the Groundwater Section, Permits
and Compliance Unit, P.O. Box 29535 Raleigh, N.C. 27626-0535 on Form GW-59
[Compliance Monitoring Report Form] every April, August, and December.
4. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
5. The OMPLIAN E BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary
for the disposal system constructed prior to December 31, 1983 is established at either (1)
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.
6. Within ninety (90) days of completion of. all monitoring wells, the permittee shall submit
two original copies of a scaled topographic map (scale no greater than 1":100') signed and
sealed by a professional engineer or a state licensed land surveyor that indicates all of the
following information:
a. the location and identity of each monitoring well,
b. the location of the waste disposal system,
c. the location of all property boundaries,
d. the latitude and longitude of the established horizontal control monument,
e. the relative elevation of the top of the well casing (which shall be known as the
"measuring point"), and
f. the depth of water below the measuring point at the time the measuring point is
established.

The survey shall be conducted using approved practices outlined in North Carolina General
Statutes Chapter 89C and the North Carolina Administrative Code Title 21, Chapter 56.
The surveyor shall establish a horizontal control monument on the property of the waste
disposal system and determine the latitude and longitude of this horizontal control
monument to a horizontal positional accuracy of +/- 10 feet. All other features listed in a.
through e. above shall be surveyed relative to this horizontal control monument. The
positional accuracy of features listed in a. through e. above shall have a ratio of precision
not to exceed an error of closure of 1 foot per 10,000 feet of perimeter of the survey. Any
features located by the radial method will be located from a minimum of two points.
Horizontal control monument 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 map shall also be surveyed using the North American Datum of 1983
coordinate system and shall indicate the datum on the map. All bearings or azimuths shall
be based on. either the true or NAD 83 grid meridian. If a Global Positioning System
(GPS) is used to determine the latitude and longitude of the horizontal control monument, a
GPS receiver that has the capability to perform differential GPS shall be used and all data
collected by the GPS receiver will be differentially corrected.
The maps and any supporting documentation shall be sent to the Groundwater Section,
N.C. Division of Environmental Management P.O. Box 29535 Raleigh, N.C. 27626-
0535.
