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 utilization 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 ground
or surface waters resulting from the operation of this facility. .
3. All wells that are constructed for purposes of groundwater monitoring shall be constructed in
accordance with 15A NCAC 02C .0108 (Standards of Construction for Wells Other than Water
Supply) and any other state and local laws and regulations pertaining to well construction.
4. Effluent limitations shall not exceed those specified in Attachment A.
5. Application rate(s), whether hydraulic, nutrient, or other pollutant shall not exceed those specified in
Attachment B.
6. The COMPLIANCE and REVIEW BOUNDARIES for the reclaimed utilization system are
established at the property boundary. Any exceedance of standards at the Compliance or Review
Boundary shall require action in accordance with 15A NCAC 02L .0106.
7. The Permittee shall apply for a permit modification prior to any sale or transfer of property that
affects a compliance boundary to establish a new compliance boundary.

10. The following shall be requirements for the reclaimed water distribution, storage, and utilization
facilities:
a. All reclaimed water valves, storage facilities, and outlets shall be tagged or labeled to warn the
public or employees that the water is not intended for drinking. Where appropriate, such warning
shall inform the public or employees to avoid contact with the water.

or otherwise marked to identify the source of the water as being reclaimed water.
i. All reclaimed water piping and appurtenances shall be either colored purple (i.e., Pantone
522) and embossed or integrally stamped or marked "CAUTION: RECLAIMED WATER —
DO NOT DRINK" or be installed with a purple (i.e., Pantone 522) identification tape or
polyethylene vinyl wrap. The warning shall be stamped on opposite sides of the pipe and
repeated every three feet or less.
ii. Identification tape shall be at least three inches wide and have white or black lettering on
purple (i.e., Pantone 522) field stating "CAUTION: RECLAIMED WATER — DO NOT
DRINK." Identification tape shall be installed on top of reclaimed water pipelines, fastened

integrity testing procedures meet water main standards in accordance with 15A NCAC 18C, but no
case shall they be less than 25 feet from a private well or 50 feet from a public well.
13. Reclaimed water distribution lines shall meet the separation distances to sewer lines in accordance
with Rule .0305 of Subchapter 02T.
14. The reclaimed water utilization system shall be connected to a rain or moisture sensor that shall
indicate when reclaimed water application is not appropriate in accordance with Condition IIIA. and
III.5. of this permit.
15. A usable green area shall be maintained for wastewater disposal. The green area shall have the
capability of accommodating the average daily flow of the facility being served without exceeding the
loading rates of the green area. A "green area", as defined in 15A NCAC 02H .0404 (g)(7), is an area
suitable for waste disposal, either in its natural state or which has been modified by planting a
vegetative cover of grasses or low growing shrubbery.

1. Adequate inspection and maintenance shall be provided by the Permittee to ensure proper operation
of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal facilities to prevent
malfunctions and deterioration, operator errors and discharges which may cause or lead to the release
of wastes to the environment, a threat to human health, or a nuisance. The Permittee shall --keep an
inspection log or summary including at least the date and time of inspection, observations made, and
any maintenance, repairs, or corrective actions taken by the Permittee. This log of inspections shall
be maintained by the Permittee for a period of five years from the date of the inspection and shall be
made available upon request to the Division or other permitting authority.
3. Any duly authorized officer, employee, or representative of the Division may, upon presentation of
credentials, enter and inspect any property, premises or place on or related to the disposal site or
facility at any reasonable time for the purpose of determining compliance with this permit; may
inspect or copy any records that must be maintained under the terms and conditions of this permit,
and may obtain samples of groundwater, surface water, or leachate.
VI. GENERAL CONDITIONS
1. Failure to abide by the conditions and limitations contained in this permit may subject the Penmittee
to an enforcement action by the Division in accordance with North Carolina General Statute 143-
215.6A to 143-215.6C.
2. This permit shall become voidable unless the facilities are constructed in accordance with the
conditions of this permit, the approved plans and specifications, and other supporting data.
3. This permit is effective only with respect to the nature and volume of wastes described in the
application and other supporting data. No variances to applicable rules governing the construction
and / or operation of the permitted facilities are granted unless specifically requested and granted in
this permit.
WQ0018755 Version 2.0 Shell Version 070320 Page 7 of ##

4. The Division accepts the data -based design flow rate of 94 gallons per day per bedroom (gpd/br) for
the community served by this system. Regardless of the adjusted design daily wastewater flow rate,
at no time shall the wastewater flows exceed the limits defined in this permit for the subject facility or
exceed the capacity of the sewers downstream of any new sewer extension or service connection(s).
The Permittee shall report the actual (measured) monthly average amount of wastewater flow
contributed per unit (gpd/pb) for the 12 months prior to renewal. If any of these values are within
20% of the approved 94 gallons per bedroom (78 gpd/pb), the permittee shall re-evaluate the
approved value using the methodology used to determine the approved flow rate and submit this
information within eighteen months of renewal. The Division may change the design flow rate for
connections to the system at that time, and upon each renewal cycle, pending an evaluation of the
submitted flow information.
The issuance of this permit does not exempt the Permittee from complying with any and all statutes,
rules, regulations, or ordinances, which may be imposed by other government agencies (local, state,
and federal) that have jurisdiction. Of particular concern to the Division are applicable river buffer
rules in 15A NCAC 02B .0200, erosion and sedimentation control requirements in 15A NCAC
Chapter 4 and under the Division's General Permit NCGO10000, and any requirements pertaining to
wetlands under 15A NCAC 02B .0200 and 02H .0500.
6. In the event there is a desire for the facilities to change ownership, or there is a name change of the
Permittee, a formal permit request must be submitted to the Division on official Division forms,
documentation from the parties involved, and other supporting materials as may be appropriate. The
approval of this request will be considered on its merits and may or may not be approved. The
Permittee of record shall remain fully responsible for compliance until a permit is issued to the new
owner.
7. The Permittee shall retain a set of approved plans and specifications for the life of the facilities
permitted herein.
8. The Permittee shall maintain this permit until all permitted facilities herein are properly closed or
permitted under another permit issued by the appropriate permitting authority.
9. The Permittee must pay the annual fee within 30 days after being billed by the Division. Failure to
pay the fee accordingly may cause the Division to initiate action to revoke this permit pursuant to
15A NCAC 02T .0105(e).
