RALEIGH
SPRAY IRRIGATION SYSTEM 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
Burnsville Car Wash
Yancey County
continued operation of a 1,000 GPD wastewater treatment facility consisting of a 30,000 gallon holding
pond, a 3 -inch discharge 5 HP pump, a 2 -inch discharge 3 HP pump, portable irrigation piping and spray
apparatus, and approximately one acre of irrigation field with enclosed berm, and all associated piping,
valves, controls, and appurtenances to serve the four wash bays of the Burnsville Car Wash with no
discharge of wastes to the surface waters, pursuant to the application received November 30, 1993, 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 December 31, 1998, and shall be
subject to the following specified conditions and limitations:
1. The spray irrigation facilities shall be effectively maintained and operated at all times so
that there is no discharge to the surface waters, nor any contamination of ground waters
which will render them unsatisfactory for normal use. In the event that the facilities fail to
perform satisfactorily, including the creation of nuisance conditions or failure of the
irrigation area to adequately absorb the wastewater, the Permittee shall take such immediate
corrective action to correct the problem, including actions as may be required by the
Division of Environmental Management.
2. 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.
3. The sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.
4. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.

5. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under
separate ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between wastewater treatment units and wells,
g) 50 feet between wastewater treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for
this waste treatment and disposal system. These buffers are not intended to prohibit or
prevent modifications, which are required by the Division, to improve performance of the
existing treatment facility. These buffers do, however, apply to modifications of the
treatment and disposal facilities which are for the purpose of increasing the flow that is
tributary to the facility. These buffers do apply to any expansion or modification of the
spray irrigation areas and apply in instances in which the sale of property would cause any
of the buffers now complied with, for the treatment and disposal facilities, to be violated.
The applicant is advised that any modifications to the existing facilities will require a permit
modification.
s
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 (ORC) of
the wastewater treatment facilities. The operator must hold a certificate of the type and
grade at least equivalent to or greater than the classification assigned to the wastewater
treatment facilities by the Certification Commission. The Permittee must also employ a
certified back-up operator of the appropriate type and grade to comply with the conditions
of Title 15A, Chapter SA, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter $A, .0202.
3. A suitable vegetative cover of the wastewater irrigation field shall be maintained.
4. Irrigation shall not be performed during inclement weather or when the ground is in a
condition that will cause runoff.
5. Adequate measures shall be taken to prevent wastewater runoff from the spray field.
6. 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.
7. The average annual weekly application rate shall not exceed 1.0 inches per acre at a daily
application rate not to exceed 0.25 inches per acre.
S. No type of wastewater other than that from $urnsville Car Wash's wash bays shall be
sprayed onto the irrigation area.
9. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
2

10. Public access to the land application sites shall be controlled during active site use. Such
controls may include the posting of signs showing the activities being conducted at each
site.
.��► is ► :►II :.'i: ► 1 �t � ►
1. Any monitoring (including groundwater, surface water, soil or plant tissue analyses)
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. Adequate records shall be maintained by the Permittee tracking the amount of wastewater
disposed. These records shall include, but are not necessarily limited to the following
information:
a) date of irrigation,
b) volume of wastewater irrigated,
C) field irrigated,
d) length of time field is irrigated,
e) continuous weekly, monthly, and year-to-date hydraulic (inches/acre) loadings for
each field,
f) weather conditions, and

4. Noncompliance Notification:
The Permittee shall report by telephone to the Asheville Regional Office, telephone no. 704/
251-6208 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 at the wastewater treatment facility which results in the treatment of
significant amounts of wastes which are abnormal in quantity or characteristic, such
as the dumping of the contents of a sludge digester; the known passage of a slug of
hazardous substance through the facility; or any other unusual circumstances.
b. Any process unit failure, due to known or unknown reasons, that render the facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, aerators, compressors, etc.
C. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass directly to receiving waters without treatment of all or any portion of the
influent to such station or facility.
d. Any time that self-monitoring information indicates that the facility has gone out of
compliance with its permit limitations.

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 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 leachate.
