Dear Mr. Jones:
In accordance with your application received September 23, 1996, we are forwarding herewith
Permit No. WQ0002428, dated January 24, 1997, to Townsend Farms, Inc. for the continued operation
of the subject wastewater treatment and spray irrigation facilities. The only modification being made to
this permit at this time is the increased spray irrigation application rate which will give an ultimate treatment
and disposal rate of 24,840 GPD. The increased treatment and disposal rate is derived from the increase in
the annual spray irrigation rate from 5.0 inches per year to 12.2 inches per year.
This permit shall be effective from the date of issuance until May 31, 1999, shall void Permit No.
WQ0002428, issued June 13, 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 150B 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.

and considered a part of this permit.
This permit shall be effective from the date of issuance until May 31, 1999, shall void Permit No.
WQ0002428, issued June 13, 1994, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE 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 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. Therefore, the residuals generated from these treatment facilities shall not
be land applied on -site unless the proper permit has been obtained from the Division.
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.

outline the actions taken or proposed to be taken to ensure that the problem does not recur.
IV. GROUNDWATER REQUIREMENTS
1. Within 90 days of permit issuance, the applicant shall submit to the Groundwater Central
Office, a detailed written copy of the sampling protocol used to take groundwater samples
for review and evaluation. The sampling protocol should be sent to the following address:
Groundwater Section, Permits and Compliance Unit, P.O. Box 29578, Raleigh, North
Carolina, 27626-0578. The sampling protocol may be modified by the Groundwater
Section if modification is deemed necessary.
2. Within 90 days of permit issuance, the applicant shall submit a groundwater sampling and
analysis plan designed to investigate the apparent occurrence of elevated nitrogen levels in
Monitor Well MW-1. The groundwater sampling and analysis plan shall be sent to the
following address: Groundwater Section, Permits and Compliance Unit, P.O_ Box 29578,
Raleigh, North Carolina, 27626-0578. The Groundwater Section will review and evaluate
the sampling and analysis plan, and may require modifications, if deemed necessary.
3. The four existing monitoring wells (MW-1, MW-2, MW-3, and MW-4) shall be sampled
every April, August and November for the following parameters:
NO3 Ammonia Nitrogen
TDS TOC
pH Water Level
Chloride Fecal Coliforms
Arsenic
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.
4

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/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.
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
working day of the month following the sampling month.
4. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.

for the disposal system constructed after December 31, 1983 is established at either (1) 250
feet from the waste disposal area, or (2) 50 feet within 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 BOUMARY 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
I . 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
to prevent malfunctions and deterioration, operator errors and discharges which may cause
or lead to the release of wastes to the environment, a threat to human health, or a nuisance.
The Permittee shall keep an inspection log or summary including at least the date and time
of inspection, observations made, and any maintenance, repairs, or corrective actions taken
by the Permittee. This log of inspections shall be maintained by the Permittee for a period
of three years from the date of the inspection and shall be made available upon request to
the Division of Water Quality or other permitting authority.
3. Any duly authorized officer, employee, or representative of the Division of Water Quality
may, upon presentation of credentials, enter and inspect any property, premises or place on
or related to the disposal site or facility at any reasonable time for the purpose of
determining compliance with this permit, may inspect or copy any records that must be
maintained under the terms and conditions of this permit, and may obtain samples of
groundwater, surface water, or leachate.
V I . GENERAL CONDITIONS

ownership, or there is a name change of the Permittee, a formal permit request must be
submitted to the Division of Water Quality accompanied by an application fee,
documentation from the parties involved, and other supporting materials as may be
appropriate. The approval of this request will be considered on its merits and may or may
not be approved.
4. Failure to abide by the conditions and limitations contained in this permit may subject the
Permittee to an enforcement action by the Division of Water Quality in accordance with
North Carolina General Statute 143-215.6(a) to 143-215.6(c).
