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
Mr. Russell A. Adams
Chatham County
FOR THE
construction and operation of a 480 GPD spray irrigation wastewater treatment and disposal system consisting
of a 1,000 gallon baffled septic tank, a 1,000 gallon pump tank (for the sand filter), a 144 square foot covered
surface sand filter (dual 72 square foot units which have free -access type covers), a tablet chlorinator, a 3,000
gallon storage/pump tank, a 1.5HP submersible irrigation pump, a 11,526 square foot spray irrigation area, and
all associated piping and appurtenances, to serve the Wendy Hill, Phase II (Lot 44), with no discharge of
wastes to the surface waters, pursuant to the application received October 8, 1999 and in conformity with the
project plan, specifications, and other supporting data subsequently filed and approved by the Department of
Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until May 31, 2000, shall void Permit No.
WQ0010882 issued 7une8, 1995, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
I 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, and other
supporting materials. If this project is to be completed_ in phases and dally certified, you shall
retain the responsibility to track further construction approved under the same permit, and shall
provide a final certificate of cam letion once the entire project has been completed. Mail the
Certification to the Non -Discharge Pernnitting Unit, 1617 Mail Service Center, Raleigh, NC
27599-1617.
2. The Raleigh Regional Office, telephone number [phone] shall be notified at least forty--
eight (48) hours in advance of operation of the installed facilities so that an in-place 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.
3. The actual spray irrigation area shall be left in a natural, wooded state, with the exception of any
vegetation adjacent to the individual sprinklers which would obstruct the sprinkler heads from

achieving their intended wetting diameter. The engineer's certification will serve as proof of
compliance with this condition_
4. In accordance with Division policy, a minimum chlorine contact time of 30 minutes shall be
provided for the treated wastewater for disinfection prior to its transference to the spray field. The
engineer shall evaluate the need for baffles in the 3,000 gallon storage/pump tank, or any other
design criteria which may be accessary to provide the minimum contact time. This evaluation (and
any resulting design changes) should be submitted to the Division with the Engineer's
certification.
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 Water Quality (Division), such as the construction
of additional or replacement wastewater treatment and disposal facilities.
b. 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.
7. The sand media of the surface sand filter must comply with the Division's sand specifications.
The engineer's certification will serve as evidence that these specifications have been met.
A leakage test shall be performed on the septic tank and dosing tank to insure that any exfiltration
occurs at a rate which does not exceed twenty (20) gallons per twenty-four (24) hours per 1,000
gallons of tank capacity. The engineer's certification will serve as proof of compliance with this
condition.
9. If excavation into bedrock is required for the installation of the septic tank or sand filter, the pit
shall be lined with a 10 mil synthetic liner.
10. A sanitary tee shall be installed on the effluent pipe of the septic tank. The engineer's certification
will serve as evidence that these specifications have been met.
11. 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 Division.
12. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
13. 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 treatment/storage units and any wells, and
g) 50 feet between 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.
II. OPERATION AND MAINTENANCE RE UIREMENTS
The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Water Pollution Control System Operators Certification
Commission (WPCSOCC), 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 Ieast equivalent to or greater than the classification
assigned to the wastewater treatment facilities by the WPCSOCC. The Permittee must also
employ a certified back-up operator of the appropriate type and grade to comply with the
conditions of 15A NCAC 8A .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class H, 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 15A NCAC 8A .0202. Once the facility is classified, the
Permittee must submit a letter to the WPCSOCC which designates the operator in responsible
charge within thirty days after the wastewater treatment facilities are 5007o complete.
A suitable year round vegetative cover of natural woodlands 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 application rate shall not exceed a cumulative loading of 25.98 inches over any twelve (12)
month period at an instantaneous application rate not to exceed 0.5 inches per hour.
7. 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.
No type of wastewater other than that from the residence on Lot 44 (Wendy Hill, Phase II) shall be
sprayed onto the irrigation area.
9. In the event that the sprinkler heads fail to achieve the design diameter of 68 feet due to
obstructions, the obstructions shall be removed or the sprinkler heads shall be raised and supported
to such height that the design diameter is achieved.
10. No traffic or equipment shall be allowed on the disposal area except while installation occurs or
while normal maintenance is being performed.
11. The Permittee is responsible for the operation and maintenance of the entire treatment and disposal
system including, but not limited to, the following items:
a. The septic tank shall be checked annually and pumped out as needed.
b. The tablet chlorinator shall be checked every week. Tablets shall be added so as to provide
proper chlorination.

c. The storage, pump, and alarm systems shall be inspected weekly. The scum layer shall be
removed at the same interval as the septic tank is cleaned out.
d. The spray system shall be inspected weekly to make certain of the sprayers proper operation,
that the vegetative growth allows a proper spray pattern, that the soil is assimilating the
disposed treated wastewater with no surface runoff, and that no objectionable odors are being
generated.
111. MONITORING AND REPORTING REQUIREMENTS
1. Any monitoring deemed necessary by the Division to insure surface and ground water protection
will be established and an acceptable sampling reporting schedule shall be followed_
2. The Permittee shall maintain records of all maintenance performed on the system and irrigation
area, as required in Condition II 11 for a minimum of five years. This information shall be
provided to the Division upon request.
3. Noncompliance Notification:
The Permittee shall report by telephone to the Raleigh Regional Office, telephone number (919)
