amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
N.T. Cox Farm
Pitt County
FOR THE
continued operation of a 1,495 GPD groundwater remediation facility consisting of two recovery wells
pumping a total of 1.0 GPM, an 80 GPM sump/influent tank with water level alarms, dual 10 GPM
pumps, a 10 GPM backwash filtration system with two 12 inch diameter by 52 inch high filter-Ag non -
hydrous aluminum silicate filter tanks in parallel, a backwash tank, a 10 GPM activated carbon filter
treatment system with four activated carbon tanks (95 pounds each) piped as two parallel pairs in series, a
20 feet by 20 feet by 4 foot deep infiltration gallery with 5 laterals having slotted screening, and all
associated piping, valves, controls, and appurtenances to serve the N.T. Cox Farm with no discharge of
wastes to the surface waters, pursuant to the application received May 29, 1997 and in conformity with the
project plan, specifications, and other supporting data subsequently filed and approved by the Department
of Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until November 30, 2002, shall void Permit
No. WQ0006761 issued October 26, 1992, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. This permit shall become voidable if the soils fail to adequately assimilate the wastes and
may be rescinded unless the facilities are installed, maintained, and operated in a manner
which will protect the assigned water quality standards of the surface waters and ground
waters.
2. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those
actions that may be required by the Division of Water Quality (Division), such as the
construction of additional or replacement treatment or disposal facilities.
3. 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.
4. Any residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the Division.

5. Diversion or bypassing of the untreated groundwater from the treatment facilities is
prohibited.
II. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Water Pollution Control Systems 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 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 holidays, and must properly manage and
document daily operation and maintenance of the facility and must comply with all other
conditions of 15A NCAC 8A .0202.
3. 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.
4. The loading rate for the infiltration gallery shall be a maximum of 2.33 GPDlsquare foot.
III. MONITORING AND REPORTING REQUIREMENTS
Any monitoring deemed necessary by the Division to insure surface and ground water
protection will be established and an acceptable sampling reporting schedule shall be
followed. `
2. Noncompliance Notification:
The Permittee shall report by telephone to the Washington Regional Office, telephone
number [phone], as soon as possible, but in no case more than 24 hours or on the
next working day following the occurrence or first knowledge of the occurrence of any of
the following:
a. Any occurrence at the groundwater remediation facility which results in the treatment of
significant amounts of contaminated groundwaters which are abnormal in quantity or
characteristic, such as the dumping of the contents of a basin or tank, 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 renders the
groundwater treatment and disposal system incapable of adequate treatment and
disposal, 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; or
d . Any time that self -monitoring information indicates that the groundwater treatment and
disposal system is not in compliance with any specified 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
Monitor wells MW-1, MW-2, MW-4, and MW-5 shall be sampled every January and July
for the following parameters:
pH
BTEX - using EPA method 602
MTBE - using EPA method 602
2. The influent and effluent from the treatment system shall be sampled every month for the
parameters specified below:
Water Levels
pH
BTEX - using EPA method 602
MTBE - using EPA method 602
The water level shall be made prior to sampling for the remaining parameters.
3. 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

5. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is
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 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.
