SINGLE FAMILY SPRAY IRRIGATION 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
Mr. Thomas H. Naylor
Orange County
FOR THE
construction and operation of a 480 GPD wastewater spray irrigation wastewater treatment and disposal
system consisting of an existing 1,200 gallon baffled septic tank, an existing 1,200 gallon sand filter pump
tank with a 20 to 25 gpm capacity pump, a minimum total of 420 ft2 dual subsurface sand filters, a tablet
chlorinator, two 1,500 gallon storage/pump tanks (piped in series) with a 20 GPM irrigation pump, and a
13,500 ft2 spray irrigation area with eleven 2.2 gpm spray heads, and all associated piping, valves,
controls, alarms, and appurtenances to serve the Naylor Residence, with no discharge of wastes to the
surface waters, pursuant to the application received March 1, 1994, 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 May 31, 1999, and shall be subject to
the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. 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. Mail the Certification to the Water Quality
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
2. The Raleigh Regional Office, telephone number 919/ 571-4700 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 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.
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 sand media of the subsurface sand filter(s) must comply with the Division's sand
specifications. The engineer's certification will serve as evidence that these specifications
have been met.
6. 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.
7. 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.
8. 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.
9. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
10. The following buffers shall be maintained, with the only buffer variances being as agreed
to in the Adjacent Landowner Agreements, that are stated as part of this permit:
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.
* Due to hardship circumstances, specific buffer variances are granted as long as existing
and/or planted vegetation buffers are maintained between the sprayfield and adjoining
homes and property lines. Three existing houses will be within 400 feet of the subject
sprayfield. These houses will be at distances of 258, 265, and 275 feet. The subject
sprayfield is to be 10 feet from the Duke Forest property line. Waivers have been
signed by the effected property owners and are considered part of this permit.
H. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. A suitable vegetative cover of the spray field shall be maintained.
3. Irrigation shall not be performed during inclement weather or when the ground is in a
condition that will cause runoff.
4. Adequate measures shall be taken to prevent wastewater runoff from the spray field.
5. The application rate shall not exceed 0.40 inches per week at an instantaneous application
rate not to exceed 0.20 inches per hour.
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. No type of wastewater other than that from the Naylor Residence shall be sprayed onto the
irrigation area.
2

8. In the event that the sprinkler heads fail to achieve the design diameter of 45 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.
9. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
10. 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.
III. MONITORING AND REPORTIN,C 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. The Permittee shall maintain records of all maintenance performed on the system and
irrigation area, as required in Condition II.10 for a minimum of five years. This
information shall be provided to the Division of Environmental Management upon request.
