(virgin) petroleum contaminated soils (excluding waste oil and heavy fuel oils) from multiple
locations to a 12.4 acre treatment and disposal area located on the east side of NC Hwy 210
approximately 0.3 mile south of the junction with NCSR 2030 in southeastern Cumberland
County, the treatment and testing of the subject soils until the soil's contamination levels are
below 10 ppm (as defined by the Division of Environmental Management's 'GUIDELINES FOR
REMEDIATION OF SOIL CONTAMINATED BY PETROLEUM'), and once acceptable
contamination levels are achieved, the land application of additional (virgin) petroleum
contaminated soils to the approved site for treatment, with no discharge of wastes to the surface
waters, pursuant to the application received March 4, 1991, 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 July 31, 1996, and shall be subject
to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
r;
1. The Fayetteville Regional Office, phone no. 919/ 486-1541, 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wastes and may be rescinded unless the facilities are installed, maintained, and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 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.
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.
Areas which are to be dedicated as buffers or are otherwise unsuitable for
contaminated soil application shall be clearly identified and shall have a cover crop
maintained on them. Approval for the cover crop to be used shall be obtained from
the Fayetteville Regional Office.
II. OPERATION AND MAINTENANCE RE-01MEMENTS
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 der ifi -wastewater tr atmentDlant op, z for to be in responsible

the type and grade at least equivalent to the classification assigned to the remediation
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 maximum thickness of application shall not exceed three (3) inches. Only soils
contaminated with gasolines, diesel, kerosene or home heating oils may be land
applied.
5. The facilities shall be effectively maintained and operated as a non -discharge system
to prevent the discharge of any wastes 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 refilled 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.
4. 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
or in the process of the application of the soil to the site and at no time shall foreign
debris be land applied with the petroleum contaminated soils. Foreign debris
removed from the land applied soil shall be removed from the site within 48 hours
after initial soil application, unless specific approval is granted by the Fayetteville
Regional Office to only accommodate emergencies or extenuating circumstances.
This foreign debris must be disposed of in a manor consistent with all statutes,
rules, regulations, or ordinances which may be imposed by government agencies
(local, state, and federal) which have jurisdiction.
11. No solid object shall be left on site that has any dimension exceeding three inches.
12. For soil being land applied that has a fine clayey texture, the land application of the
soil shall be in very thin layers (one inch or less) and serially incorporated into the
upper six inches of the site soil before each following layer is added until a
maximum of three inches of contaminated soil has been applied.
111. MONITORING AND RFPORTING REQUIREMENTS
I . 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 Fayetteville Regional Office,
telephone no. 919/ 486-1541, 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.

K

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.
3. There shall be no land application of soils contaminated by a petroleum fuel source
not regulated under the Federal Underground Storage Tank Rules (40 CFR Part
280), unless both of the following stipulations have been met;
a. The contaminated soils have been tested in accordance with the Toxicity
Characteristic Revision Rules as specified in the March 29, 1990 Federal
Register (p. 11798 - 11877), and;
b. For any soil in which one or more constituents exceed the regulatory level
specified in (a), a written clearance is required from this Departments
Division of Solid Waste Management that the contaminated soil is not
subject to regulation by programs administered under its authority.
4. For each source of contaminated soil, the following information must be submitted
to the Fayetteville Regional Office;

n
not subject to the Underground Storage Tank Regulations (40 CFR part 280);
Nosourcga'of contaminated soils shall be land applied prior to receiving written
authorization from the Fayetteville Regional Office.
1V. GROUNDWATER REQUIREMENTS
Prior to beginning waste disposal operations, six (b) monitor wells, one (1)
upgradient and two (2) downgradient, one (1) at the compliance boundary nearest
the closest residential potable well (southwest), one (1) in the direction of
groundwater flow (northwest and north), and one on the southeast side closest to
the road and nearest house in that direction shall be installed at the location shown
on the attached map to monitor groundwater duality. The wells shall be constructed
such that the water level in the well is never above or below the screened (open)
portion of the well at any time during the year. However, the exact location and
construction details for these wells shall be approved by the Fayetteville Regional
Office, from which a well construction permit must be obtained.
4

2. The monitor wells must be sampled initially after construction ( and prior to waste
disposal operations) and thereafter every March, July, and November for the
following parameters:
TOC pH (6.5-8.5 Standard units)
Water Level Total Suspended Solids
TDs (500.0)
Volatile Organic Compounds - (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 "Method For The Determination Of Organic Compounds
In Drinking Water", U.S. EPA - 600/4-88/039
The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (top of well casing) of all monitoring wells shall be surveyed
to provide relative elevations of the measuring point for each of the monitoring
wells. The depth of water in each well shall be measured from the surveyed point
on the top of the casing.
The numbers in parentheses represent the maximum allowable concentrations in
groundwater for the various analytical parameters, as specified in 15 NCAC 2L
[Groundwater Classifications and Standards]. Unless otherwise noted, the
concentrations are given in parts per million.
If TOC concentrations greater than 10 mg/l 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 TQC
concentration as measured in the back rg ound 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.
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.
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management on Form GW -59 (Compliance Monitoring Report
Form) every April, August, and December.
3. The Com liance Boundary,delineated on the attached site map for the disposal
system is specified by regulations in 15 NCAC 2L, Classifications and Water
Quality Standards applicable to the groundwater of North Carolina. An exceedance
of Groundwater Quality Standards beyond the Compliance Boundary is subject to
penalty provisions applicable under ,Ueneral tatute 143-215.6(1)a. jThe sale of
eFf. oflrq�i property, by the Permittee, which is within or contiguous to disposal system
site may alter the location of the Compliance Boundary.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the land application area, or 50 feet
within the property boundary.
If the title to any property which may affect the location of the Compliance
5

Boundary is changed, the permittee shall notify the Division Director within 14
days. The Director shall then establish a modified Compliance Boundary which
will be done as a modification to the Permit.
The REVIEW BOUNDARY for the disposal system is specified by regulations in
15 NCAC 2L, Groundwater Classifications and Standards. A REVIEW
BOUNDARY is established around disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. When the
concentration of any substance equals or exceeds the maximum allowable
concentration of that substance at the REVIEW BOUNDARY, as determined by
monitoring, the permittee shall either (i) demonstrate, through predictive
calculations or modeling, that natural site conditions, facility design and
operational controls will prevent a violation of standards at the Compliance
Boundary; or, (ii) submit a plan for the alteration of existing site conditions, facility
design or operational controls that will prevent a violation of standards at the
Compliance Boundary, and implement that plan upon its approval by the Director.
4. Any additional groundwater quality monitoring, as deemed necessary by the
Division, shall be provided.
5. 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.
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
Fayetteville Regional Office, to the attention of the Regional Hydrogeological
Supervisor, within 30 days of sample collection.
6. Soils contaminated with petroleum products shall not be applied to an area which
has previously received petroleum contaminated soils unless analysis of soil
samples taken from the site indicates that contaminant levels have been reduced to
below 10 ppm.
7. The land application of petroleum contaminated soils shall be limited to the area
shown on the attached site map.
8. Within 45 days of permit issuance, Oak Hill Farms shall develop and submit to the
Fayetteville Regional Office a site management plan.
9. Separate land application areas shall be maintained for each disposal project,
separated by a 5 foot buffer. Each area will be labeled to correspond with a reap
identifying the source of the soil. This map shall be submitted to the Regional
Office along with other required monitoring reports.
10. A temporary cover crop shall be established on the land application areas after the
second month tilling and every subsequent tilling.
11. The land application of soils contaminated with any products other than Class I or
Class II gasolines, diesel, kerosene and/or home heating oils is prohibited.

12. All buffer zones as prescribed in 15A NCAC 2H.0219 shall be observed.
V. INSPECTIONS
I . 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 purpose of determining compliance with this permit;
may inspect or copy any records that must be kept under the terms and conditions
of this permit; or may obtain samples of groundwater, surface water, or Ieachate.
