In accordance with your application received February 5, 1992, and your request for permit
modification received July 6, 1992, we are forwarding herewith Permit No. WQ0006138, dated July 15,
1992, to Orange Water and Sewer Authority for the construction and operation of a 975 GPD LPP
subsurface wastewater disposal system. The modifications addressed by this permit are elimination of the
48 hour backfill notice, changing of the field loading rate from 0.075 GPD/sq. ft. to 0.3 GPD/sq. ft.,
elimination of LPP references, and elimination of water meter requirement in lieu of pump records.
This permit shall be effective from the date of issuance until May 31, 1997, and shall be subject to
the conditions and limitations as specified therein. Please pay particular attention to the monitoring
requirements in this permit. Failure to establish an adequate system for collecting and maintaining the

SUBSURFACE DISPOSAL 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
Orange Water and Sewer Authority
Orange County
FOR THE
construction and operation of a 975 GPD subsurface wastewater disposal system consisting of a 2000
gallon septic tank, 1500 gallon pump tank with duplex 35 GPM pumps and high water alarms, a 2 inch
force main to pressure manifold, and six 4 inch gravity feed 180 foot long nitrification laterals in a 3240
square foot nitrification field to serve Cane Creek Reservoir with no discharge of wastes to the surface
waters, pursuant to the application received February 5, 1992, and your request for permit modification
received July b, 1992, 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, 1997, and shall be subject to
the following specified conditions and limitations:
I. IERFORMANCE 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. Mail the Certification to the Permits and Engineering Unit, P.O. Box
29535, Raleigh, NC 27626-0535.
2. The Raleigh Regional Office and the Orange County Health Department shall be notified at
least 72 hours prior to initiation of construction of the system. No equipment shall allowed
on the site except that which is directly required for system installation. If other
construction is progressing around the site, the immediate nitrification field area shall be
fenced off to prohibit other traffic. The Raleigh Regional Office, phone no. 9191571-4700,
shall be notified of any significant changes made in the design or installation of the installed
facilities (including any changes ordered by other agencies) 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. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those
as may be required by this Division, such as construction of additional or replacement
wastewater treatment or 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. This permit shall become voidable if the soils fail to adequately absorb the wastes and may
be rescinded unless the facilities are installed, maintained, and operated in a manner which
will protect the assigned water quality standards of the surface waters and ground waters.
6. Adequate measures shall be taken to divert stormwater from the disposal area and prevent
wastewater runoff from the subsurface disposal field. This includes taking little or no extra
measures if naturally occurring measures are adequate.
7. 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.
8. A usable reserve area shall be maintained for wastewater disposal. The reserve area shall
have the capability of accommodating the average daily flow of the facility being served
without exceeding the loading rates of the reserve area while meeting all required buffer
requirements.
9. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
10. The following buffers shall be maintained:
a) 100 feet between disposal area and any public or private water supply including
wells
b) 100 feet between disposal area and "SA and SB" classified surface waters
C) 50 feet between disposal area and any stream, lake, river or natural drainageway
d) 50 feet between disposal area and property lines
e) 10 feet between disposal area and surface water interceptor drains or diversions
(upslope)
f) 25 feet between disposal area and surface water interceptor drains or diversions
(downslope) and groundwater drainage systems.
11. 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)
hour per 1,000 gallons of tank capacity. The engineer's certification will serve as proof of
compliance with this condition.
12. Due to the WS classification of the adjacent waters, an Operation and Maintenance manual
shall be completed and presented to all operation personnel prior to the system start up. The
O&M manual shall address but not be limited to power failure situations and what methods
will be taken to insure that no risks are posed to the reservoir. Standby power will be
required if portable water will be used at any time at these facilities, as the site is to be
served by an existing well with pumps. No portable water shall be used until standby
power is provided.

OPERATION AND MAINTENANCE REQUIREMENTS
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

prevent the discharge of any wastewater resulting from the operation of this facility.
5. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
