Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until November 30, 2009, and shall be subject to
the following specified conditions and limitations:
This permit shall become voidable unless the facilities are constructed in accordance with the conditions of
this permit, the approved plans and specifications, and other supporting data.
2. This permit is effective only with respect to the nature and volume of wastes described in the application

established and an acceptable sampling reporting schedule shall be followed.
13. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to insure proper
operation of the subject facilities.
14. The Permittee or his designee shall inspect the wastewater recycle 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 maintain an inspection log or

groundwater, surface water, or leachate.
16. The annual administering and compliance fee must be paid by the Permittee within thirty (30) days after

life of this project.

20. Groundwater Requirements:
a. Well Construction / Abandonment Criteria:
Upon reactivation of this facility, all water supply wells within the compliance boundary shall be
permanently abandoned. Within thirty (30) days of abandonment, a Well Abandonment Record
(GW-30 form) shall be completed for each well abandoned and mailed to the address listed in the
"Reporting / Documentation" section of the Groundwater Requirements. The well(s) must be
abandoned by either a North Carolina Certified Well Contractor, the property owner, or the
property lessee according to General Statutes 87-98.4(b)(2). If the abandonment is not performed
by a certified well contractor, the property owner or lessee must physically perform the actual well
abandonment activities and the well(s) must be abandoned according to the North Carolina Well
Construction Standards (15A NCAC 2C .0113) and local county rules.
b. Sampling Criteria:
i. Upon reactivation of this facility, monitor wells MW-1, MW-2, and MW-3 shall be sampled
initially before reactivation, and thereafter every November for the parameters listed below. Prior
to sampling the parameters, the measurement of water levels must be taken. 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 relative to a common datum.
pH Total Organic Carbon Water Level
ii. For Total Organic Carbon (TOC), if concentrations greater than 10 mg/1 are detected in any dpwst-
gradient 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 down -gradient wells shall be subject to the additional sampling and analysis
as described above.
iii. Any laboratory selected to analyze parameters must be Division of Water Quality certified for those
parameters required.
c. Reporting / Documentation:
i. All reports and documentation (GW-30, GW-59) shall be mailed to the following address:
NCDENR-DWQ
Information Processing Unit
1617 Mail Service Center
Raleigh, NC 27699-1617
Updated blank forms (GW-30, GW-59) may be downloaded from the Aquifer Protection Section's
website at http://gw.ehnr.state.nc.us/ or requested from the address mentioned above.
ii. The results of the sampling and analysis must be received on Form GW-59 (Groundwater
Quality Monitoring: Compliance Report Form) by the Aquifer Protection Section (address
listed in the "Reporting / Documentation" section of the Groundwater Requirements), on or
before the last working day of the month following the sampling month. The data of all
groundwater sampling analyses required by the permit conditions must be reported using the
most recent GW-59 form along with attached copies of the laboratory analyses.

d. Applicable Boundaries:
i. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A
NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary for the disposal
system individually permitted prior to December 30, 1983 is established at either 500 feet from the
waste disposal area, or 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 remediation action according to 15A NCAC 2L .0106(d)(2).
ii. The 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 action in accordance with 15A NCAC 2L .0106(d)(1).
e. Additional Requirements:
i. Any additional water quality monitoring, as deemed necessary by the Division, shall be provided.
ii. Prior to plant reactivation, monitor wells MW-1, MW-2, and MW-3 shall be inspected every
November to ensure the wells are in compliance with 15A NCAC 02C .0108 Well Construction
Standards. Records of such inspections must be maintained. Each monitoring well must be labeled
as required by 15A NCAC 02C .0108 (c)(11).
iii. Results from groundwater samples collected at MW-1, MW-2, and MW-3 from 2000-2003 must be
submitted to the Aquifer Protection Section at the above address within 30 days of permit issuance.
21. Noncompliance Notification:
The Permittee shall report by telephone to the Raleigh 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 wastewater treatment facility which results in the treatment of significant
amounts of wastes 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 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; or
d. Any time that self -monitoring information indicates that the facility is not in compliance with its permit
limitations.
Occurrences outside normal business hours may also be reported to the Division's Emergency Management
personnel at telephone number [phone], or [phone]. 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.

22. Upon classification of the wastewater treatment and spray irrigation facilities by the Water Pollution
Control System Operators Certification Commission (WPCSOCC), the Permittee shall designate and
employ a certified operator to be in responsible charge (ORC) and one or more certified operator(s) to be
back-up ORC(s) of the facilities in accordance with 15A NCAC 8G .0201. The ORC shall visit the
facilities in accordance with 15A NCAC 8G .0204 or as specified in this permit and shall comply with all
other conditions specified in these rules.
23. The Permittee, at least six (6) months prior to the expiration of this permit, shall request its extension.

it may deem appropriate.
