RALEIGH
SURFACE IRRIGATION 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
Colonial Pipeline Company
Guilford County
FOR THE
continued operation of a 7,140 gallon per day (GPD) surface irrigation treatment and disposal facility
consisting of a holding tank, an oil/water separator, an air stripping unit, a 257,000 gallon clay -lined
aerated lagoon with two 5 HP aerators, approximately 420 linear feet of three inch suction line, an 80
GPM pump station, approximately 2,511 linear feet of three inch distribution force main, 2,820 linear feet
of four inch force main, 17 spray heads, 3.69 acres of spray area, and all associated pipe fittings, valves,
and appurtenances to serve Colonial Pipeline Company, with no discharge of wastes to the surface waters,
pursuant to the application received January 9, 2002, and subsequent additional information received by
the Division, 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 September 30, 2010, shall void Permit
No. WQ0006317 issued July 15, 1997, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
The surface 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, 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 drainage ways 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 that 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 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 wastewater treatment and irrigation facilities by the Water Pollution
Control System Operators Certification Commission (WPCSOCC), the Permittee shall designate and
employ a certified operator to be in responsible charge (ORC) and one or more certified operator(s) to
be back-up ORC(s) of the facilities in accordance with 15A NCAC 8G .0201. The ORC shall visit
the facilities in accordance with 15A NCAC SG .0204 or as specified in this permit and shall comply
with all other conditions specified in these rules.
3. A suitable year round vegetative cover 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 irrigation field.
b. 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 33.75 inches over any twelve (12)
month period at an instantaneous application rate not to exceed 0.15 inches per hour.
8. No type of wastewater other than that from Colonial Pipeline Company shall be irrigated onto the
irrigation area.
9. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while
normal maintenance is being performed.
10. Public access to the land application sites shall be controlled during active site use. Such controls
may include the posting of signs showing the activities being conducted at each site.

11. A protective vegetative cover shall be established and maintained on all earthen basin: embankments
(outside toe of embankment to maximum pumping elevation), berms, pipe runs, erosion control areas,
and surface water diversions. Trees, shrubs, and other woody vegetation shall not be allowed to grow
on the earthen basin dikes or embankments. Earthen basin embankment areas shall be kept mowed or
otherwise controlled and accessible.
12. The soil in the spray areas shall be maintained above a pH of 6.5,

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
