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may be rescinded unless the facilities are installed, maintained, and operated in a manner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.
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 the 44,842 cubic feet of petroleum contaminated soil from
Eslon Thermoplastics shall be placed in the earthem bermed disposal area. Should
additional soil contamination be found written approval must be obtained from the
Mooresville Regional Supervisor prior to beginning remedial activities.
7. Upon completion of construction and prior to operation of this permitted facility, a
certification must be received from a professional engineer certifying that the permitted
facility has been installed in accordance with this permit, the approved plans and
specifications. Mail the Certification to the Permits and Engineering Unit, P.O. Box
29535, Raleigh, NC 27626-0535.
11. 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. Once the facility is classified, the Permittee must submit a letter
to the Certification Commission which designates the operator in responsible charge within
thirty days after the remediation facilities are 50% complete.
3. Adequate measures shall be taken to prevent surface runoff from carrying any disposed
material into any surface waters.
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 contaminated soils shall be adequately limed to a soil pH of at least 6.5 prior to being
placed in the treatment area. The lime shall be thoroughly incorporated into the
contaminated soils.

6. To ensure that sufficient oxygen is provided for waste biodegradation, the contaminated
soils shall be retilled at periods of one month, two months, and every six months thereafter
following initiation of treatment.
7. No food -chain crops shall be grown on the treatment/disposal sites for at least two years
following the completion of contaminated soil application and remediation.
Nutrients, in the form of nitrogen and phosphorus fertilizers, must be applied over the
treatment area and fully incorporated into the contaminated soil. To provide maximum
benefits, fertilization should occur no sooner than 15 days nor later than 30 days
subsequent to initiation of treatment.
Rate of fertilizer application should be the lesser 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).
9. All foreign debris shall be removed from the petroleum contaminated soil prior to land
initiation of treatment and at no time shall foreign debris be land applied or disposed of with
the petroleum contaminated soils.
III. MONITORING AND REPORTING REQUIREMENTS
1. 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 Mooresvile 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 contaminated soils' treatment program which results in the
treatment or land application of significant amounts of wastes which are abnormal
in quantity or characteristic.
b. Any failure of the contaminated soils' treatment program resulting in a discharge of
wastes to receiving waters.
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
