Carolina as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
E. T. Environmental Incorporated
Randolph County
W61191-110.
operation of a (virgin) petroleum contaminated soils disposal system consisting of land application
and treatment of tested (Class I and CLass II) (virgin) petroleum contaminated soils from multiple
locations to a six (6) acre treatment and disposal area located at NCSR 1406 approximately one
mile from the intersection of NCSR 1408 and NCSR 1406, near Archdale N.C., the treatment and
testing of the subject soils until the soil's contamination levels are below detection limits (as
defined by the Division of Environmental Management's 'GUIDELINES FOR REMEDIATION
OF SOIL CONTAMINATED BY PETROLEUM'), and once contamination levels below
detection limits 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 April 17, 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 March 31, 1996, and shall be
subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. The Winston-Salem Regional Office, phone no. 919/ 761-2351, shall be notified at

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wastes and may be rescinded unless the facilities are installed, maintained, and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.

€Y
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. The land application of soils contaminated with any products other than Class I or
Class II petroleum products is prohibited, unless specifically authorized by the
Division.
7. The Iand application of petroleum contaminated soils shall be limited to the 5.9
acres contained in the submitted EROSION CONTROL PLAN drawn by

4. 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.
5. The site shall be adequately limed to a soil pH of at least 6.5 and fertilized prior to
disposal of the contaminated soil. The contaminated soil, fertilizer and lime shall be
thoroughly incorporated into the top six to eight inches of the native soils by tilling
or disking.
6. 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.
7. 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.
8. Upon classification of the facility by the Certification Commission, the Permittee
shall employ a certified waste 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

ems. -
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 later than 30
days subsequent to disposal.
Rate of fertilizer application should be the Iesser of the following:
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).
III. 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

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
