other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
County of Chatham
Chatham County
FOR THE
continued operation of a 300-GPD spray irrigation treatment and disposal facility consisting of 1,000-gallon baffled
septic tank, a 141-square foot pressure -dosed sand filter, a 1,000-gallon sand filter pump tank, a tablet chlorinator, a
2,000-gallon storage/pump tank, a 40-GPM pump with audible and visual alarms, and a 10,395-square foot spray
irrigation area to serve 12 employees at the County of Chatham's Jordan Lake Water Treatment Plant, with no
discharge of wastes to the surface waters, pursuant to the application received December 28, 1998, and in conformity
with the project plans, 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, 2004, shall void Permit No. WQ0009589
issued July 29, 1994, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
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.
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 Division.
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, and
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.
II. OPERATION AND MAINTENANCE REQUIREMENTS
1. 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, the Permittee shall employ a certified spray irrigation system operator to be in responsible
charge (ORC) of the spray irrigation system. The operator must hold a valid spray irrigation system
certificate and must visit the subject system as often as necessary to insure the proper operation of the
system but in no case less than twice per year with a six month interval between visits. The ORC must
properly manage and document the operation and maintenance of the system and must comply with all
other conditions of Title 15A, Chapter 8G, .0204.
3. A suitable year-round vegetative cover shall be maintained.
4. lmgation 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 application rate shall not exceed a cumulative loading of 16.9 inches over any 12-month period at an
instantaneous application rate not to exceed 0.20 inches per hour.
No type of wastewater other than that from the Jordan Lake Water Treatment Plant shall be sprayed onto
the irrigation area.
No traffic or equipment shall be allowed on the disposal area except while normal maintenance is being
performed.
10. The spray irrigation field shall be fenced with at least a two -strand wire fence.

III. MONITORING AND REPORTING REQUIREMENTS
Any monitoring (including groundwater, surface water, soil or plant tissue analyses) deemed necessary by
the Division to insure surface and ground water protection will be established and an acceptable sampling
reporting schedule shall be followed.
The Permittee shall maintain records of all maintenance performed on the system and irrigation area, as
required in Condition V. 2. 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 [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:
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 five
days following first knowledge of the occurrence. This report must outline the actions taken or proposed
to be taken to ensure that the problem does not recur.
IV. GROUNDWATER REQUIREMENTS
1. Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided.
