FOR THE
operation of a contaminated soils remediation system consisting of disposing of approximately 52
cubic yards of petroleum contaminated soil from an underground storage tank located at Southern
Bell Telephone's Selma facility to a 5,663 square foot disposal area located approximately 300
feet north of the junction of S.R. 1380 and S.R. 1386 with no discharge of wastes to the surface
waters, pursuant to the application received November 29, 1990 and in conformity with the
project plan, specifications, and other supporting data subsequently filed and approved by the
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 February 28, 1996, and shall be
subject to the following specified conditions and limitations:
1. PERFORMANCE STANDARDS
The Mooresville Regional Office, phone no. [phone], shall be notified at
least twenty-four (24) hours after land application of the contaminated soil so that
an inspection can be made. Such notification to the regional supervisor shall be
made during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday
through Friday, excluding State Holidays. In addition the Lincoln County Manager
shall be informed at least 24 hours prior to beginning remediation activities.
2. 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wastes and may be rescinded unless the facilities are installed, maintained, and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.
3. 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 as may be required by this Division, such as the construction of additional or
replacement treatment or disposal facilities.
4. 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.

5. The following buffers shall be maintained:
a) 100 feet between disposal area and any public or private water supply including
wells
b) 100 feet between disposal area and "SA and SB" classified surface waters
c) 50 feet between disposal area and any stream, lake, river or natural drainageway
d) 50 feet between disposal area and property lines
e} 10 feet between disposal area and surface water interceptor drains or diversions
(upslope)
f) 25 feet between disposal area and surface water interceptor drains or diversions
(downslope) and groundwater drainage systems.
6. No contaminated soil other than that from Southern Bell Telephone's Selma facility
shall be placed on the land disposal site.
I1. OPERATION AND MAINTENANCE RE UIREMENT
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Certification Commission, the Permittee
shall employ a certified wastewater treatment plant operator to be in responsible
charge of the wastewater treatment facilities. The operator must hold a certificate of
the type and grade at least equivalent to the classification assigned to the wastewater
treatment facilities by the Certification Commission. Once the facility is classified,
the Permittee must submit a letter to the Certification Commission which designates
the operator in responsible charge.
3. Adequate measures shall be taken to prevent surface runoff from carrying any
disposed material into any surface waters.
4. The 52 cubic yards of contaminated soil shall be spread to a thickness not to exceed
3 inches on at least 0.13 acres of land at the disposal site.
5. 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.
6. The site shall be adequately limed to a soil pH of at least 6.5 prior to disposal of the
contaminated soil. The contaminated soil and time shall be thoroughly incorporated
into the top six to eight inches of the native soils by tilling or disking.
7. To ensure that sufficient oxygen is provided for waste biodegradation, the site shall
be retilled at periods of one month, two months, and every six months thereafter
following disposal.
8. No food -chain crops shall be grown on the landfarming sites for at least two years
following the completion of contaminated soil application and remediation.
9. Nutrients, in the form of nitrogen and phosphorus fertilizers, must be applied over
the disposal area and fully incorporated into the mixed contaminated and native soil
layer. To provide maximum benefits, fertilization should occur no sooner than 15
days nor later than 30 days subsequent to disposal.
Rate of fertilizer application should be the lesser of the following:
2

a) For nitrogen, the tolerance level of the vegetative crop, as determined by a
knowledgeable party, or 75-100 pounds per acre plant available nitrogen
(PAN).
b) For phosphorus, the tolerance level of the vegetative crop, as determined by a
knowledgeable party, or 50-75 pounds per acre P205 (or equivalent).
10. All foreign debris shall be removed from the petroleum contaminated soil prior to
land application and at no time shall foreign debris be land applied with the
petroleum contaminated soils.
Ill. MONITORING AND REPORTING REQUIREMENTS
Any monitoring deemed necessary by the Division of Environmental Management
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 no. [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 with the land application program which results in the land
application of significant amounts of wastes which are abnormal in quantity or
characteristic.
b. Any failure of the land application program resulting in a discharge of wastes to
receiving waters.
c. Any time that self-monitoring information indicates that the facility is not in
compliance with the conditions and limitations of this permit or the parameters
on which the system was designed.
d. Any process unit failure, due to known or unknown reasons, that render the
facility incapable of adequate sludge treatment.
e. Any spillage or discharge from a vehicle or piping system transporting
contaminated soil to the application site.
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.
IV. GROUNDWATER REQUIREMENTS
Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
2. Soil samples will be collected, from a minimum of two (2) areas at the disposal site,
at intervals of six months and twelve months following disposal.
3

Each sample will be composed of the vertical column of soil, extending from land
surfaces to the maximum depth of waste incorporation, and collected by using a soil
auger, Shelby tube or split -spoon sampler.
Samples at each location will be thoroughly mixed and a representative portion
analyzed to determine the concentration of (1) Petroleum Fuel Hydrocarbons
(Method 3550) and (2) any Volatile Organic Aromatic (VOA) compounds present.
A copy of the laboratory results of the soil analysis will be submitted to the
Mooresville Regional Office, to the attention of the Regional Hydrogeological
Supervisor, within 30 days of sample collection.

collected from the underlying undisturbed soil to determine if any infiltration of
petroleum contamination has occurred. The samples shall be analyzed for TPH in
accordance with the GUIDELINES FOR REMEDIATION OF SOIL
CONTAMINATED BY PETROLEUM (August 1990). Results of TPH analysis
shall be submitted to the Mooresville Regional Office, to the attention of the
Regional Hydrogeological Supervisor, within 30 days of sample collection.
V. INSPECTIONS
Adequate inspection, maintenance, and cleaning shall be provided by the Permittee
to insure proper operation of the subject facilities.
2. The Permittee or designee shall inspect the contaminated soil area to prevent any
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 keep an inspection log or
summary including at least the date and time of inspection, observations made, and
any maintenance, repairs, or corrective actions taken by the Permittee. This log of
inspections shall be maintained by the Permittee for a period of three years from the
date of the inspection and shall be made available upon request to the Division of
Environmental Management or other permitting authority.
