which is 20 ft x 15 ft x I ft (L x W x D) and cell B which is 20 ft x 15 ft x 2 ft, flow level control
structures to serve the wetland cells, a Model 100 Jet -Chlor tablet chlorinator, a 1,500 gallon pump tank
with a 24 GPM submersible pump with high water alarms, a spray field with 12 sprinklers each with a
spray diameter of 50 ft, and all the associated piping, valves, and appurtenances to serve the Doris King
Residence, with no discharge of wastes to the surface waters, pursuant to the application received October
7, 1993, and in conformity with the project plan, specifications, and other supporting data subsequently

No. WQ0004512 issued July 7, 1992, and shall be subject to the following specified conditions and
limitations:
I . 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 assimilate the wastewater, the Permittee shall take immediate
corrective actions including those actions that may be required by the Division of
Environmental Management, such as the construction of additional or replacement
wastewater treatment and disposal facilities.
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 residuals generated from these treatment facilities must be disposed 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 existing residence or places of public assembly
under separate ownership,
b) 150 feet between wetted area and property lines with a minimum distance of 63 feet
between the spray field and the properties of Allphoradia Forman and Anzilia K.
Andersoni,
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 treatment/storage units and any wells, and
g) 50 feet between treatment units and property lines.
The Permittee shall maintain a vegetative buffer of sufficient height to prevent the
occurrence of drift at all times between the spray field and the adjacent property
boundaries.
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.
H. QPER.A IIQN AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. A suitable vegetative cover shall be maintained.
3. Irrigation shall not be performed during inclement weather or when the ground is in a

Facilities having a rating of one through four points, inclusive,
do n.-1 require a certified operator. Classification of all other
facilities requires a comparable grade operator in responsible
charge.
Facilities having an activated sludge process will be assigned
a minimum classification of Class If.
Facilities having treatment processes for the removal of metal
or cyanide will be assigned a minimum classification of Class 11.
Faci#flies having treatment processes for the biological removal
of phosphorus will be assigned a minimum classification of Class
III.
In-planl processes and related control equipment which are an
integral part of induslriaE production shall not be considered waste
treatment. Likewise, discharges of wastewater from residences
having a design flow of 1,000 gpd or fess, shall not be subject to
ratinc.
