In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended,
and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Burlington Industries, Inc.
Gaston County
FOR THE
continued operation of a 9,000 GPD evaporative lagoon system consisting of 9,000 GPD extended aeration
package plant with a barscreen, aeration, clarification, tablet chlorination with a 285 gallon chlorine contact tank,
and a 0.5 acre evaporative lagoon to serve the Burlington Industries, Inc.'s Gaston Terminal, with no discharge of
wastes to the surface waters, pursuant to the renewal request received March 5, 1998, 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 April 30, 2003, shall void Permit No.
WQ0000612 issued November 15, 1993, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
The evaporative lagoon system 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, 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.
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.
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.
Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.

The following buffers shall be maintained:
a) 400 feet between the evaporative lagoon and any residence or places of public assembly under
separate ownership,
b) 150 feet between the evaporative lagoon and property lines,
c) 100 feet between the evaporative lagoon and wells,
d) 100 feet between the evaporative lagoon and drainageways or surface water bodies,
e) 50 feet between the evaporative lagoon 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.
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 11, 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 8A.0202.
The facilities shall be effectively maintained and operated as a non -discharge system to preventthe
discharge of any wastewater resulting from the operation of this facility.
4. Freeboard in the evaporative lagoon shall not be less than two feet at any time.
No type of wastewater other than that from Burlington Industries, Inc.'s Gaston Terminal shall be
disposed in the evaporative lagoon.
Public access to the evaporative lagoon shall be controlled during active site use. Such controls may
include the posting of signs showing the activities being conducted at each site.
III. MONITORING AND REPORTING REQUIREMENTS
1. 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 Mooresville Regional Office, telephone number (704)
663-1699, 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
The two existing monitor wells, MW -1 and MW -2, shall be sampled every November for the
following parameters:
Water Level
pH .
Volatile Organic Compounds
(A) Standard Method 6230D, PQL at 0.5 ug/L or less
(B) Standard Method 621 OD, PQL at 0.5 ug/L or less
(C) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or less
(D) EPA Method 8260, Low Concentration, PQL at 0.5 ug/L or less
(E) Another method with prior approval by the Groundwater Section Chief
Any method used must meet the following qualifications:
(1) A laboratory must be DWQ certified to run any method used.
(2) The method used must, at a minimum, include all the constituents listed in Table VIII of
Standard Method 6230D.
(3) The method used must provided a PQL at 0.5 ug/L or less which must be supported by
laboratory proficiency studies as required by the DWQ Laboratory Certification Unit.
Any constituents detected above the MDL but below the PQL at 0.5 ug/L must be
qualified (estimated) and reported.
If any volatile organic compounds are detected by the methods listed, then the Mooresville Regional
Office Groundwater Supervisor, telephone number [phone], must be contacted immediately
for further instructions regarding any additional follow-up analyses required. The results of all initial
and follow-up analyses must be submitted simultaneously.

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.
If TOC concentrations greater than 10 mg/I 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 TQC
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.
2. 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

The following definitions shall apply throughout this Subchapter.
(t) Activated Carbon Beds. A physicallchemical method for raducing soluble organic malarial- from wastewater effluent; The column -type beds used in this
method will have a flow rate varying from two to eight gallons per minute per square ioot and may be either upflow or downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatmant plant she;
(2) Aerated Lagoons. A basin In which all solids are maintained In suspension and by which biological oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow-through basls;
(3) Aeration. A process of bringing about intimate contact between air or high purity oxygen in a liquid by spraying, agitation or diffusion;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(4) Agriculturally managed site. Any site on which a crop Is produced, managed,.and harvested (Crop includes grasses, grains, trees, etc.);
(5) Air Stripping. A process by which the ammonium Ion is first convened to dissolved ammonia (pH adjustment) with the ammonia then 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 extremely high tampermures which volatilize and oxidize the
absorbed Impurities;
(7) Carbonaceous Stage. A stage of wastewater treatment designed to achieve 'secondary effluent Ilmhs;
(8) Centrifuge. A mechanical device in which centrifugal force Is used to separate solids from Slquids or to separate flqulds of different densNas;
(9) Chemical Addition Systems- The addition of chemical(s) to wastewater at an application point for purposes of Improving solids removal, pH adjustment,
alkalinity control, etc.; the capability to experiment with different chemicals and cNierern application pofnts to achieve a spacft result will be considered one
system; the capability to add chemicals) to dvaJ units will be rated as one system; capablitty to add a chemical at a different application points for different
purposes will rasuft In the systems being rated as separate systems;
(10) Chemical Sludge'Conditloning. The addition of a chemical compound such as lime, ferric chloride, or a polymer to wet sludge to Coalesce the mass prior to
Its appiicatlon to a dewatering device;
(t 1) Closed Cycle Systema. Use of holding ponds or holding tanks for containment of wastewater containing Inorganic, non-toxlc materlafs from sand, gravel,
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping facilities or any other appurtenances;
(12) Combined Removal of Carbonaceous 1300 and Nitrogenous Removal by Nitrification- A single stage system required to achieve permit effluent tknits on BOO
and ammonia nitrogen within the same biological reactor,
(13) DecNorinatlon. The partial or complete reduction of residual chlorine In a llquld by any chemical or physical process;
