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 November 30, 2005, shall void Permit No.
WQ0004942 issued March 22, 1996, and shall be subject to the following specified conditions and limitations:
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 (Division), 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 Genera.
Statute 143-2I5.1 and in a manner approved by 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.
II. OPERATION AND MAINTENANCE REQUIREMENTS
The facilities shall be properly maintained and operated at all times.
Upon classification of the facility by the Water Pollution Control System Operators Certification
Commission (WPCSOCC), 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 WPCSOCC. The Permittee must also employ a certified back-up operator of the
appropriate type and grade to comply with the conditions of 15A NCAC 8G .0202. The ORC of the
facility must visit each Class I facility at least weekly and each Class II, III, and IV facility at Ieast 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 15A NCAC SG .0202.
A suitable year round vegetative cover of shall be maintained.
4. Irrigation shall not be performed during inclement weather or when the ground is in a condition that will
cause runoff.
Adequate measures shall be taken to prevent wastewater runoff from the spray field.
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 a cumulative loading of 52.0 inches over any twelve (12) month
period at an instantaneous application rate not to exceed 0.165 inches per hour.
No type of wastewater other than that from Perquimans Middle School 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 storage lagoon shall not be less than two feet at any time.
III. MONITORING AND REPORTING REQUIREMENTS
Any monitoring (including groundwater, surface water, soil or plant tissue analyses) deemed necessary by

values shall be calculated by dividing monthly flow volume by the number of days in the month.
4. The effluent from the subject facilities shall be monitored by the Permittee at the point prior to irrigation
every March for the following parameters:
BOD5 TSS
Fecal Coliform pH
NH3 as N
Three (3) copies of all operation and disposal records (as specified in condition III 2) on Form NDAR-1
and three (3) copies of all effluent monitoring data (as specified in condition III 3 and III 4) on Form
NTDMR-1 shall be submitted on or before the Iast day of the following month. All information shall be

contents of a sludge digester; the known passage of a slug of hazardous substance through the facility;
or any other unusual circumstances.
b. Any process unit failure, due to known or unknown reasons, that render the facility incapable of
adequate wastewater treatment such as mechanical or electrical failures of pumps, aerators,
compressors, etc.
c. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-pass directly to
receiving waters without treatment of all or any portion of the influent to such station or facility.
d. Any time that self -monitoring information indicates that the facility has gone out of compliance with
its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter form within five
(5) days following first knowledge of the occurrence. This report must outline the actions taken or
proposed to be taken to ensure that the problem does not recur.
IV. GROUNDWATER REQUIREMENTS
1. Monitor wells MW-1, MW-2, and MW-3 shall be sampled annually every March for the following
parameters:
Water Level pH
Chloride Total Dissolved Solids (TDS)
Fecal Coliforms Total Organic Carbon (TOC)
Nitrate (NO3) Total Ammonia
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.
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.
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, 1636
Mail Service Center Raleigh, N.C. 27699-1636 on or before the last working day of the month following

(2) 50 feet within the property boundary, whichever is closest to the waste disposal area. An exceedanc,.
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).
4. In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal systems

operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal facilities to prevent
