CONTAMINATED SOILS DISPOSAL PERMIT
-------------------------------------------------------------------
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
First Union National Bank
Wilkes County
FOR THE
operation of a contaminated soils remediation system consisting of disposing of approximately 500 cubic
yards of petroleum contaminated soil from the Oakwoods Complex to a 81,000 square foot disposal area
located at the Oakwood Complex with no discharge of wastes to the surface waters, pursuant to the
application received May 7, 1991 and in conformity wit,'t 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 June 30, 1996 and shall be subject to
the following specified conditions and limitations:
JERFORMANCE STANDARDS
The Winston-Salem 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.
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may be rescinded unless the facilities are installed, maintained, and operated in a manner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 Y(1ror1F3il
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 First Union National Bank 's Oakwoods
Complex shall be placed on the land disposal site.
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 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. [
3. Adequate measures shall be taken to prevent surface runoff from carrying any disposed
material into any surface waters.
4. The 500 cubic yards of contaminated soil shall be spread to a thickness not to exceed two
inches on at least 1.9 acres of Iand 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 lime 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 land farming 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 followin�(y:
2

IV.
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 P2O5 (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.
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 Winston-Salem 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 wastKwhich 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.
C. 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.
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 Iaboratoty results of the soil analysis will be submitted to the Winston-Salem
Regional Office, to the attention of the Regional Hydrogeological Supervisor, within 30
days of sample collection.

1. 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.
3. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the disposal site and facility at any reasonable time for the
