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.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 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.
19. 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 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 Title 15A, Chapter 8A, .0202.
20. Within 60 days of permit issuance, the Permittee shall inspect the dike wall and certify that
the physical integrity of the wall complies with permit requirements.
21. Monitoring wells MW-1, MW-2, and MW-3 (see attached map) shall be sampled every
April, August, and November for the following parameters:
Chloride Phosphorus
Fecal Coliform TDS
NOz TOC
NO3 Water Level
pH
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
3

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.
22. 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.
23. If any volatile organic compounds are detected by method 6230D, or the equivalent method
502.2, then EPA methods 604 and 611 must also be run to detect other organic compounds
which may be present The results of all analyses specified in the monitoring requirements,
including 604 and 611 if required, must be submitted simultaneously.
24. 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 May, September, and December.
25. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
26. The COMPLIANCE BOJINDARY 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.
27. Within sixty (60) days of permit issuance, the Permittee shall submit two original copies of
a scaled topographic map (scale no greater than V: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 all components 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.
11

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 +/- 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.
28. The Permittee, at least six (6) months prior to the expiration of this permit, shall request its
extension. Upon receipt of the request, the Commission will review the adequacy of the
facilities described therein, and if warranted, will extend the permit for such period of time
and under such conditions and limitations as it may deem appropriate.
29. The Permittee shall control the vegetation around the treatment lagoons.

A004 DEf1NMIONS
The following definitions shall apply throughout this Subchapter.
(1) Activated Carbon Beds. A physlcaVchem€cal method for reducing tolvble organic malarial from wastewater elllusM; The column -type beds used In this
rom method will have a flow rasa varying ftwo to eight parlors per minute per square w fool and may be shher upfioor downflow rarbon beds. Carbon may or
may not be ragenerated on the wastewater treatmarl plant she;
(2) Aerated Lagoons. A basin In which all solids are maintained In suspension and by which b€oioglcal oxidation or organic matter is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Asratlon. A process of bringing about Intimate contact between air or high purity oxygen In a liquid by spraying, aghation or cil luslon;(3a) blended
Aeration. An ac1€valed sludge process utilizing a minimum hydraulic detention time of 1$ hours.
(4) Agriculturally managed she. Any site on which a crop Is produced, managed, and harvested (Crop Includes grasses, grains, tract, atc.);
(5) Air Stripping, A process by which the ammonlum Ion Is first converted to dissotved ammonia (pH adjustment) with the Ammonia than released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene, toluene, and xylene;
(6) Carbon Regeneration The regeneration of exhausted carbon by the use of a furnace to provide extramsty i lempermures which volatilize and oxidize the
absorbed €mpurid";
(7) Carbonaceous Stage. A stsge of wastewater treatment designed to achieve 'secondary effluent Ilmhr,
(8) Centrifuge. A mechanical device In which centrffvgal force Is used to separate solids from liquids or to separate liquids of dfierertt deraMes;
(9). Chemical Addition Systems- The addhlon of chsmkal(s) to wastewater at an application point for purposes of Improving solids removal, pH ad]usimerl,
alkalinhy control, etc.; the capability to experiment with dtlisranl chemicals and eNfererrt application points to achieve a specfric result will be considered one
•,-Vam; the capability to add chemicals) to dual unlit will be rated as or* system; capability to add a chemical at a different applicatlon points for different
roses will result In the systems being rated as separate syslams;
Chemical Sludge Conditioning, The addhlon of a chemical compound such as lime, ferric chloride, or a polymer to wet sludge to aWasce the mass prior to
a application to a dewatering device-
(11) Closed Cycle Systems. Use of I iding ponds or holding links for containment of wastewater contalning inorganic, non -toxic materials from sand, gravel,
Crushed stone or other slmilar oparallons. Such systems shall Carty a rr,axlmum of two paints regardless of pumping facilities or any other appurtenances:
112) Combined Removal of Carbonaceous SOD and Nitrogenous Removal by Nhrtfication- A s ngls slage system required 10 achieve permit alliuert limt,s on BOD
and ammonia nllrogen within the same biological reactor,
(13) Dechlorinatlom The par€a3 or complete raduction of residual chlortre In a liquid by any chemical or physical process;
(14) DenhrHication Process. The conversion of nitrate-nhropen to nitrogen gas;
